+环境准备好后，接下来本文以Hi3861平台为例，演示如何利用HPM进行组件的安装、编译和打包。
+
+1.  执行以下命令，初始化安装目录（目录名可自行设置）：
+
+    ```
+    mkdir test3861
+    cd test3861
+    hpm init -t dist
+    ```
+
+    初始化成功则显示：
+
+    ```
+    Initialization finished.
+    ```
+
+2.  安装wifi\_iot发行版。
+
+    ```
+    hpm install @ohos/wifi_iot
+    ```
+
+    安装成功则显示：
+
+    ```
+    Installed.
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >Hi3516平台采用下述命令：
+    >```
+    >hpm install @ohos/ip_camera_hi3516dv300
+    >```
+    >Hi3518平台采用下述命令：
+    >```
+    >hpm install @ohos/ip_camera_hi3518ev300
+    >```
+
+3.  编译打包
+
+    ```
+    hpm dist
+    ```
+
+    编译成功会显示：
+
+    ```
+    {{name}}: distribution building completed.
+    ```
+
+4.  上述所有命令执行成功后，在 ./out 目录下会生成编译结果，开发者可以将编译结果烧录到对应的开发板上进行测试。

+## linux服务器<a name="section20979554791"></a>
+
+准备一台装有Ubuntu 16.04 及以上 64 位系统的linux服务器（hpm是支持windows的，但是目前OpenHarmony开源的Hi3861、Hi3516、Hi3518三个解决方案都只支持Ubuntu）。
+
+将linux shell改为bash：
+
+```
+ls -l $(which sh)
+# 如果指向的不是bash，则按以下方式修改：
+# 方法一：执行以下命令，然后选择no
+dpkg-reconfigure dash
+# 方法二：先删除sh，再重新创建软连接
+rm -f /bin/sh
+ln -s bash /bin/sh
+```
+
+## 安装Node.js<a name="section9954105413153"></a>
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>如果配置的源的nodejs版本太低，可以执行以下语句后再执行apt-get install：
+>```
+>curl -L https://deb.nodesource.com/setup_12.x | bash
+>```
+
+推荐安装 Node.js 12.x （包含 npm 6.14.4）或更高版本（推荐 12.13.0+）：
+
+```
+sudo apt-get install nodejs
+sudo apt-get install npm
+```
+
+查看版本：
+
+```
+node --version  # 查看nodejs版本
+npm --version   # 查看npm版本
+```
+
+## 安装HPM<a name="section15937194904819"></a>
+
+通过 Node.js 自带的 npm（使用默认的源 https://registry.npmjs.org/ ）安装 hpm-cli 命令行工具：
+
+```
+npm install -g @ohos/hpm-cli
+```
+
+安装完hpm-cli命令行工具后，执行以下命令可以查看hpm配置：
+
+```
+hpm config
+```
+
+上述命令执行后将会显示hpm的默认配置，您可以根据自己的喜好对默认配置进行修改，以下是hpm的常用配置：
+
+```
+registry = https://hpm.harmonyos.com              # hpm注册中心地址，下载组件必须
+strictSsl = true                                  # 通过https连接时，是否需要校验证书
+http_proxy = http://your-proxy-server:port        # 配置HTTP代理
+https_proxy = http://your-proxy-server:port       # 配置HTTPS代理
+```
+
+hpm-cli的命令介绍可以参考：[hpm操作命令](bundles-standard-rules.md)
+
+## 安装python环境<a name="section1621819180417"></a>
+
+需使用python3.7以上版本，采用以下命令进行安装：
+
+```
+sudo apt-get install python3.8
+sudo apt-get install python3-pip
+sudo pip3 install setuptools
+sudo pip3 install kconfiglib  # 建议安装kconfiglib 13.2.0+版本
+```
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>上述方式适用Hi3518和Hi3516两种平台，针对Hi3861平台采用以下方式安装python环境：
+>```
+>sudo apt-get install python3.8
+>sudo apt-get install python3-pip
+>sudo pip3 install setuptools
+>sudo pip3 install kconfiglib  # 建议安装kconfiglib 13.2.0+版本
+>sudo pip3 install pycryptodome
+>sudo pip3 install six --upgrade --ignore-installed six
+>sudo pip3 install ecdsa
+>```
+
+如果当前系统中既存在python2又存在python3，参考以下方法将默认python修改为python3：
+
+```
+ll `which python`
+rm /usr/bin/python
+ln -s python3.8 /usr/bin/python
+```
+
+## 安装文件打包工具<a name="section77617165913"></a>

+
+## 创建OpenHarmony组件<a name="section1976410130540"></a>
+
+创建OpenHarmony组件有如下几种方式：
+
+-   从头开发一个全新的组件。
+-   将一个现有的非组件的代码改造成组件。
+-   hpm提供了一些组件模板方便快速创建组件。
+
+## 新建组件<a name="section717481119145"></a>
+
+通常情况下，[HPM网站](https://hpm.harmonyOS.com)上能找到您开发常用的组件，如果现有的组件不能完全满足开发，这时可以自己动手开发一个组件。
+
+如果您愿意，可以将组件发布到HPM的仓库中供其他用户使用。假设要在D:/source目录下新建一个全新的组件my-bundle：
+
+可以使用hpm init 创建该组件的脚手架代码，例如，进入D:/source目录，执行如下命令：
+
+```
+hpm init -t default  -d demo my-bundle
+```
+
+会在 source 目录下生成如下文件：
+
+```
+mybundle
+├── bundle.json      # 组件元数据描述文件
+├── example          # 测试组件功能的示例
+│   └── main.c
+├── include            # 组件的内部头文件
+│   └── mybundle.h
+├── README.md        # 组件的简要说明
+└── src              # 组件的源代码
+     └─ mybundle.c
+```
+
+接下来根据您的业务需要，实现组件内部的功能代码，完成代码开发后，通过git将代码（包括bundle.json文件）提交到组件代码托管仓库中（如gitee）。
+
+## 改造组件<a name="section102861955201410"></a>
+
+如果您已经有了代码，只是还不满足OpenHarmony的组件结构，需要改造成为hpm的组件包，只需要在当前要改造的代码目录下（例如mybundle2），执行如下命令，会提示您输入组件名称和版本。
+
+```
+hpm init
+```
+
+1.  输入名称后回车（如mybundle2）。
+2.  输入版本后（如1.0.0）回车，在当前组件目录下会生成一个bundle.json文件。
+3.  打开bundle.json文件再添加其他的描述，这时候他已经是一个具备可发布的组件了。
+
+    ```
+    $ hpm init
+    Your bundle will be created in dirname E:\demo\mybundle2
+    ? bundle name mybundel2
+    ? version 1.0.0
+    Init finished!
+    ```
+
+
+1.  打开bundle.json文件修改其他信息（如作者，代码仓库，代码目录，命令脚本，依赖组件等），如下：
+
+    ```
+    {
+    "name": "mybundle2",
+    "version": "1.0.0",
+    "publishAs": "source",
+    "dirs":{
+    ".":[
+    "README.md"
+        ],
+    "src":[
+    "test.c"
+        ],
+    "header":[
+    "header/test.h"
+        ],    
+    "src/common":[
+    "src/common/foobar.txt"
+        ]
+      },
+    "scripts": {
+    "build": "make -${args}"
+      },
+    "dependencies": {
+    "@ohos/cjson": "^1.0.0",
+    "@ohos/": "^1.2.0"
+      }
+    }
+    ```
+
+
+## 从模板创建组件<a name="section15882846181510"></a>
+
+hpm 除了提供了默认模板 default和simple两个简单的模板之外，其他模板均存储在服务器端。
+
+可以使用命令hpm search -t template 从服务器端搜索模板。
+
+![](figure/zh-cn_image_0000001051452177.png)
+
+根据description简要中的描述，找到适合的模板，基于模板可以快速创建一个组件的脚手架，执行如下初始化命令（指定-t -d 参数）。
+
+```
+hpm init -t {templatename} -d dir name
+```
+
+-   \{templatename\} ：指的是模板名称。
+-   -d 后面的参数dir：是要创建的组件所存放的路径。
+-   name：为要创建的组件名称。
+
+## 编译组件<a name="section136732148541"></a>
+
+完成代码开发后，需要对组件进行编译。hpm提供了命令集成的能力，您可以选择任意的适合项目的编译工具（如make，gcc，gn等等）。只需在当前项目的bundle.json文件中定义scripts脚本中的build命令，就可以通过执行hpm build执行编译。
+
+## 定义编译脚本<a name="section10274147111610"></a>
+
+以编译一个app目录下helloworld可执行文件为例：
+
+```
+app
+├── BUILD.gn
+├── include
+│   └── helloworld.h
+└── src
+    └── helloworld.c
+```
+
+在helloworld.c同级目录下新建一个BUILD.gn
+
+```
+touch BUILD.gn
+vim BUILD.gn
+```
+
+以下是BUILD.gn的样例，仅供参考
+
+```
+executable("hello_world") {
+    sources = [
+        "src/helloworld.c"
+    ]
+
+    include_dirs = [
+        "include"
+    ]
+}
+```
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   “executable”是gn内置模板，可以用“gn help executable ”查看使用方法。
+>-   “sources ”是源码路径，“include\_dirs ”是头文件路径。
+
+## 执行编译<a name="section879301916172"></a>
+
+在当前文件夹下，执行编译命令：
+
+```
+hpm build
+```
+
+在完成一系列的编译动作后，显示build succeed。检查编译的输出结果：
+
+![](figure/zh-cn_image_0000001051770876.png)
+
+## 定义发行版<a name="section413216495619"></a>
+
+发行版是将一组组件组合起来的，编译生成可以运行的OpenHarmony解决方案，里面包含了较多依赖的组件，以及以脚本形式描述如何完整编译、链接这些组件。
+
+## 定义脚本<a name="section11503171219190"></a>
+
+bundle.json中定义
+
+```
+{
+"name": "my_dist",
+"version": "1.0.0",
+"publishAs": "distribution",
+"scripts": {
+"dist": "make -${args}"
+  },
+"base": {
+"name": "dist-bundle",
+"version": "1.0.0"
+  },
+"envs": {
+"args": "x86"
+  },
+"dependencies": {
+}
+}
+```
+
+## 发行<a name="section4694125521912"></a>
+
+在当前发行版根目录下，执行如下命令。
+
+```
+hpm dist
+```
+
+hpm-cli工具会自动执行编译，打包操作，将根据scripts定义的dist脚本生成镜像文件，如：
+
+```
+out
+|-xxdist.img
+|-xx.file
+```
+
+## 烧录<a name="section1746331545413"></a>
+
+发行版的编译结果可以烧录到设备中运行，例如使用hiburn工具进行烧录。在发行版的bundle.json文件配置烧录参数。
+
+```
+"scripts": {
+"flash": "{$DEP_HIBURN}/hiburn"
+},
+```
+
+配置烧录相关的参数（参考烧录工具的说明进行配置）。
+
+```
+hpm run flash
+```
+
+## 运行调试<a name="section6742131615549"></a>
+
+将发行版的镜像烧录到设备中后，就可以启动运行调试了，由于运行调试和具体的开发板和IDE调试工具相关，此处不再详细描述。

+
+## 安装Node.js和hpm命令行工具<a name="section106591616205311"></a>
+
+1.  安装Node.js。
+
+    从官网下载并在本地安装Node.js.
+
+    推荐安装  [Node.js](https://nodejs.org/)  12.x \(包含 npm 6.14.4\)或更高版本 \(推荐 12.13.0+\)。
+
+2.  通过Node.js自带的npm安装hpm-cli命令行工具。执行以下命令：
+
+    ```
+    npm install -g @ohos/hpm-cli
+    ```
+
+3.  安装完成后执行如下命令，显示hpm版本，即安装成功。
+
+    ```
+    hpm -V  或 hpm --version
+    ```
+
+4.  （可选）如果需要升级hpm版本，请执行如下命令：
+
+    ```
+    npm update -g @ohos/hpm-cli
+    ```
+
+
+## 更改hpm的配置（可选）<a name="section71821165412"></a>
+
+安装完hpm-cli命令行工具后，执行以下命令可以查看hpm配置：
+
+```
+hpm config
+```
+
+上述命令执行后将会显示hpm的默认配置，您可以根据自己的喜好对默认配置进行修改，以下是hpm的常用配置：
+
+```
+registry = https://hpm.harmonyos.com/hpm/registry/api              # hpm注册中心地址，下载组件必须
+login = https://hpm.harmonyos.com/hpm/auth/pk                      # hpm处理登录地址，发布组件必须
+loginUser = {your-account}                                         # 配置hpm登录账号，发布组件必须
+shellPath = C:\WINDOWS\System32\cmd.exe                            # hpm命令执行使用的shell
+globalRepo = C:\Users\yourname\.global                             # 配置全局安装的组件存放路径
+http_proxy = http://your-proxy-server:port                         # 配置HTTP代理
+https_proxy = http://your-proxy-server:port                        # 配置HTTPS代理
+```
+
+hpm-cli的命令介绍可以参考：[hpm操作命令](bundles-guide-overview.md)
+
+## 下载OpenHarmony代码<a name="section102338221707"></a>
+
+参考[《源码获取》](../get-code/sourcecode-acquire.md)。
+
+## 安装开发依赖的组件<a name="section19233183315020"></a>
+
+hpm包管理器将常用开发开发工具（如烧录，编译，压缩等）也发布成了组件。可以通过如下命令方式进行安装，执行完该命令后，系统会自动将开发依赖的工具下载安装，且这些组件只需全局安装一次。
+
+```
+hpm i -g @ohos/llvm
+hpm i -g @ohos/ninja
+hpm i -g @ohos/gn
+hpm i -g @ohos/hc_gen
+hpm i -g @ohos/sysroot
+```
+
+这是一组开发工具的组件包（如包含gn，ninja等工具），有了这些开发态的组件，就可以进行常规的源码组件的开发了。

+
+## 概述<a name="section1725818533344"></a>
+
+本文档将介绍组件的基本概念以及如何按照规范定义组件。
+
+### 定义<a name="section4821219183514"></a>
+
+OpenHarmony软件以组件\(bundle\)作为基本单元，从系统角度看，凡是运行在OpenHarmony上的软件都可以定义为组件；一般来讲，根据组件的应用范围，可以分为：
+
+-   板级组件：如board、arch、mcu这些与设备硬件相关的组件。
+-   系统组件：一组独立功能的集合，如内核、文件系统、框架等。
+-   应用组件：直接面向用户提供服务的应用\(如wifi\_iot，ip\_camera\)。
+
+从形式上看，组件是为复用而生，一切可以复用的模块都可以定义为组件，可以分为：
+
+-   源代码
+-   二进制
+-   代码片段
+-   发行版
+
+### 组件划分原则<a name="section1089794263513"></a>
+
+原则上应尽可能划分为细颗粒度的组件，以满足最大限度的复用。主要考虑以下几点：
+
+-   独立性：组件的功能应该相对独立，支持独立编译，可以单独对外提供接口和服务；
+-   耦合性：如果组件必须依赖其他的组件，才能对外提供服务，应考虑和被依赖的组件合并为一个组件。
+-   相关性：如果一组组件共同完成一项功能，且没有被其他组件依赖，未来也没有被依赖的可能，则可以考虑合并为一个组件。
+
+### 组件依赖<a name="section25701647163710"></a>
+
+组件的依赖关系分为两种：必选依赖和可选依赖。
+
+-   必选依赖：是指组件A在完成某个功能时，必须引入组件B，调用B的接口或服务配合才能完成。称B为A的必选依赖。
+-   可选依赖：是在组件A在完成某个功能时，可以引入组件C，也可以引入组件D。C和D可以相互替换，称C和D为A的可选依赖。
+
+## 组件构成<a name="section185538333914"></a>
+
+一个组件包一般包含如下内容：
+
+-   组件包的代码或库（src目录下的代码文件）
+-   ohos\_bundles文件夹（存放依赖的组件，安装组件时自动生成，无需提交到代码库）
+-   组件包的说明文件\(README.md\)
+-   组件包元数据声明文件\(bundle.json\)
+-   开源许可文件\(LICENSE\)
+
+    ```
+    my-bundle
+       |_ohos_bundles
+       |_src
+       |_bundle.json
+       |_README.md
+       |_LICENSE
+    ```
+
+
+### 代码文件<a name="section8431268393"></a>
+
+组件的代码文件和普通的代码目录没有差异。但要注意的是，组件中对外暴露的接口（头文件），会被其他组件所引用，需要单独在bundle.json的dirs中声明。
+
+### 说明文件<a name="section168121548173914"></a>
+
+README.md，为markdown格式的描述关于组件自述说明文件。（[语法参考](https://www.markdownguide.org/getting-started/)\)
+
+为了帮助他人在hpm上找到该组件，并更方便的使用它，在组件的根目录中包含一个README文件。
+
+README文件可能包括如何安装，配置和使用组件包中的实例代码说明，以及可能会对用户有所帮助的任何其他信息。
+
+每个组件的自述文件将显示在hpm系统的组件详情页面的描述中。
+
+### 元数据描述文件<a name="section7107181819406"></a>
+
+bundle.json文件是对当前组件的元数据描述，每个组件中必须包含一个bundle.json文件。
+
+```
+{
+  "name": "@myorg/demo-bundle",
+  "version": "1.0.0",
+  "license": "MIT",
+  "description": "bundle description",
+  "keywords": ["hos"],
+  "tags": ["applications", "drivers"],
+  "author": {"name":"","email":"","url":""},
+  "contributors":[{"name":"","email":"","url":""},{"name":"","email":"","url":""}],
+  "homepage": "http://www.foo.bar.com",
+  "repository": "https://git@gitee.com:foo/bar.git",
+  "publishAs": "code-segment",
+  "segment":{
+     "destPath":"/the/dest/path"
+  },
+  "dirs": {
+    "src": ["src/**/*.c"],
+    "headers": ["headers/**/*.h"],
+    "bin": ["bin/**/*.o"]
+  },
+  "scripts": {
+    "build": "make"
+  },
+  "envs": {},
+  "ohos": {
+    "os": "2.0.0",
+    "board": "hi3516",
+    "kernel": "liteos-a"
+  },
+ "rom": "10240",
+ "ram": "1024",
+ "dependencies": {
+    "@myorg/net":"1.0.0"
+ }
+}
+```
+
+bundle.json文件具有如下功能：
+
+-   name：定义组件的名称，放到组织下， 以@开头，/分割，如：@myorg/mybundle
+
+-   version：定义组件版本号，如1.0.0，需满足semver的标准。
+
+-   description：一句话对组件进行简要的描述。
+-   dependencies：定义组件的依赖组件。
+
+-   envs： 定义组件编译时所需要的参数，包括全局参数以及依赖所需的参数。
+
+-   scripts：定义在当前组件下能够执行的命令（如编译，构建，测试，烧录等）。
+
+-   publishAs：定义组件的发布类型（source：源码，binary：二进制，distribution：发行版，code-segment：代码片段）。
+
+-   segment: 仅针对code-segment类型的组件，定义组件的目标路径（即安装后，组件包中包含的文件复制到的目标路径）
+-   dirs：定义发布时打包的目录结构（如头文件）。
+
+-   ram&rom：统计相关信息：预计占用ROM和RAM信息。
+-   ohos：描述OpenHarmony系统版本、开发板及内核的匹配关系（多个请用英文逗号的“,”分割）。
+-   定义其他扩展信息：作者，主页，代码仓库，许可协议，标签，关键字。
+-   对于发行版类型，还有个base，可以定义继承自的发行版。
+
+## 组件管理<a name="section32061634104110"></a>
+
+### 依赖关系<a name="section791115242423"></a>
+
+生成基础bundle.json以后，需要继续添加组件依赖来实现更复杂的功能。此时需要知道所依赖组件的名称和版本号，并且把它们定义在bundle.json里面的dependencies字段中。
+
+```
+{
+    "name": "my-bundle",
+    "version": "1.0.0",
+    "dependencies": {
+        "net": "1.0.0"
+    }
+}
+```
+
+上述示例中，my-bundle组件依赖于net 1.0.0组件。在全局安装了 hpm CLI 工具之后，执行如下命令可以从远端仓库获取到依赖：
+
+```
+hpm install 
+```
+
+依赖获取以后，会保存到当前组件根目录下到ohos\_bundles文件夹中。组件以及依赖之间会形成一个依赖关系的树状结构。全局安装了 hpm CLI 工具之后，在组件根目录下执行如下命令：
+
+```
+username@server MINGW64 /f/showcase/demo/demo
+$ hpm list
++--demo@1.0.0
+| +--@huawei/media@1.0.2
+| +--@demo/sport_hi3518ev300_liteos_a@1.0.0
+| | +--@demo/app@4.0.1
+| | | +--@demo/build@4.0.1
+| | | +--@demo/arm_harmonyeabi_gcc@4.0.0   
+| | +--@demo/liteos_a@4.0.0
+| | | +--@demo/third_party_fatfs@4.0.0     
+| | | +--@demo/arm_harmonyeabi_gcc@4.0.0   
+| | +--@demo/init@4.0.0
+| | +--@demo/dist_tools@4.0.0
+```
+
+还可以使用可视化的形式，来查看当前组件的依赖关系，执行如下命令：
+
+```
+hpm ui
+```
+
+会在本地启动一个web服务（默认会打开浏览器并进入项目页），点击侧边栏的项目依赖图标，打开页面，可以看到项目的依赖组件列表，点击右侧按钮切换到树状视图，就可以看到依赖关系的图形化展示\(如下图\)。

+## 组件版本<a name="section12612142864316"></a>
+
+### 版本号命名规范<a name="section1487612416432"></a>
+
+名称需要为全小写字母，中间可以使用中划线或者下划线分隔。比如 "bundle", "my\_bundle"。
+
+版本号的格式为 "主版本号.次版本号.修订号" 或 "主版本号.次版本号.修订号-先行版本号"，比如 "1.0.0"， "1.0.0-beta"，详细规格可以参考  [https://semver.org](https://semver.org/)。
+
+### 版本发布<a name="section1548171014440"></a>
+
+为了使组件能被其他开发者使用，组件需要上传到远端仓库。组件上传使用如下命令：
+
+```
+hpm publish
+```
+
+命令执行以后，系统会对的整个依赖关系进行检查，下载缺失依赖组件。依赖检查完成后，如果发布类型为binary，系统会对整个组件进行编译，生成二进制文件，然后打包上传。如果使其他上传类型，则直接根据定义的打包规则进行打包，然后上传。
+
+注意：发布组件需要用户账号登录，需要先拥有hpm的系统账号后，并注册组织，申请组织认证通过后，才拥有发布的权限。
+
+## 发行版<a name="section1264139114413"></a>
+
+发行版通常是将一系列组件组合起来，成为编译可以运行的OpenHarmony解决方案镜像，里面包含了多个依赖的组件，以及脚本，用于描述如何完整编译、链接这些组件。
+
+发行版本身通常不需要包含功能实现代码，仅包含bundle.json描述（设置publishAs为distribution）和一些编译脚本组成。
+
+因为发行版编译的过程需要系统提供环境变量，所以发行版使用scripts脚本中内置的dist命令：
+
+```
+{
+    "publishAs":"distribution",
+    "scripts": {
+        "dist": "script compile command"
+    }
+}
+```
+
+编译执行使用如下命令：
+
+```
+hpm dist 
+```
+
+重新定义一个发行版所具有的功能是一个复杂的过程，所以系统允许对发行版进行继承，从而在现有功能的基础上进行定制。继承发行版需要在bundle.json中定义base字段。
+
+```
+{
+    "base": {
+        "name": "dist_wifi_iot",
+        "version": "1.0.0"
+    }
+}
+```
+
+上述定义表明当前组件继承自发行版组件dist-wifi-iot 1.0.0。
+
+发行版由很多的依赖组件组成，通过bundle.json中的dependencies段来描述，有些依赖是必须的，有些依赖则是根据可以需求增加或删除的。bundle.json中名称前带有？的依赖表示可选依赖，继承它的发行版，可以移除掉该可选组件，再增加别的组件进行替换。
+
+```
+{
+    "dependencies": {
+        "?my_bundle": "1.0.0"
+    }
+}
+```
+
+上述声明表示my\_bundle依赖可以被移除。如果想要移除my\_bundle，在上层依赖方需要使用excludes关键字来进行定义
+
+```
+{
+    "excludes": [ "my_bundle" ]
+}
+```
+
+依赖被移除后，就不会参入组件的构建过程。只有标记为可选的依赖才能够被移除，强行移除未被标记的依赖会出现错误提示。
+
+## 环境变量说明<a name="section15352105174512"></a>
+
+组件在编译的过程中需要依赖系统提供的环境变量来自定义输出，链接所需二进制文件等等。这里提出的环境变量均指根据需求把所需变量注入脚本执行的上下文中。所以在脚本中可以直接获取到变量的值。下面介绍当前系统存在的几种环境变量。
+
+全局变量由bundle.json中的envs属性来定义。整个组件中的依赖都可以获取到全局变量定义的值。
+
+```
+{
+    "envs": {
+        "compileEnv": "arm"
+    }
+}
+```
+
+不同组件在引入依赖的过程中可以传入不同的参数，从而使依赖的编译可以满足当前组件的需求。依赖中定义的参数可以在对应依赖脚本执行的上下文中获取到。
+
+```
+{
+    "dependencies": {
+        "my-bundle": {
+            "version": "1.0.0",
+            "mode": "debug"
+        }
+    }
+}
+```
+
+组件在链接二进制文件的时候，需要知道二进制文件在依赖中的路径，所以依赖的路径会作为环境变量传入编译组件中。
+
+传入的环境变量的格式为DEP\_BundleName，BundleName为依赖的名称，例如 DEP\_first\_bundle。
+
+依赖中可以定义标签，对引入的依赖进行分组。在脚本中可以根据标签，获得这一组依赖的路径。定义的标签以\#开头，具体定义的方式为：
+
+```
+{
+    "dependencies": {
+        "#tool": {
+            "first-bundle": "1.0.0",
+            "second-bundle": "1.0.0"
+        },
+        "#drivers": {
+            "xx-bundle": "1.0.0",
+            "yy-bundle": "1.0.0"
+        }
+    }
+}
+```
+
+系统中存在两个固定环境变量：
+
+-   DEP\_OHOS\_BUNDLES：表示ohos\_bundles文件夹所在的路径。
+-   DEP\_BUNDLE\_BASE：表示最外层组件的路径。

-
-## 安装Node.js和hpm命令行工具<a name="section106591616205311"></a>
-
-1.  安装Node.js。
-
-    从官网下载并在本地安装Node.js.
-
-    推荐安装  [Node.js](https://nodejs.org/)  12.x \(包含 npm 6.14.4\)或更高版本 \(推荐 12.13.0+\)。
-
-2.  通过Node.js自带的npm安装hpm-cli命令行工具。执行以下命令：
-
-    ```
-    npm install -g @ohos/hpm-cli
-    ```
-
-3.  安装完成后执行如下命令，显示hpm版本，即安装成功。
-
-    ```
-    hpm -V  或 hpm --version
-    ```
-
-4.  （可选）如果需要升级hpm版本，请执行如下命令：
-
-    ```
-    npm update -g @ohos/hpm-cli
-    ```
-
-
-## 更改hpm的配置（可选）<a name="section71821165412"></a>
-
-安装完hpm-cli命令行工具后，执行以下命令可以查看hpm配置：
-
-```
-hpm config
-```
-
-上述命令执行后将会显示hpm的默认配置，您可以根据自己的喜好对默认配置进行修改，以下是hpm的常用配置：
-
-```
-registry = https://hpm.harmonyos.com/hpm/registry/api              # hpm注册中心地址，下载组件必须
-login = https://hpm.harmonyos.com/hpm/auth/pk                      # hpm处理登录地址，发布组件必须
-loginUser = {your-account}                                         # 配置hpm登录账号，发布组件必须
-shellPath = C:\WINDOWS\System32\cmd.exe                            # hpm命令执行使用的shell
-globalRepo = C:\Users\yourname\.global                             # 配置全局安装的组件存放路径
-http_proxy = http://your-proxy-server:port                         # 配置HTTP代理
-https_proxy = http://your-proxy-server:port                        # 配置HTTPS代理
-```
-
-hpm-cli的命令介绍可以参考：[hpm操作命令](组件管理.md)
-
-## 下载OpenHarmony代码<a name="section102338221707"></a>
-
-参考[《源码获取》](../get-code/源码获取.md)
-
-## 安装开发依赖的组件<a name="section19233183315020"></a>
-
-hpm包管理器将常用开发开发工具（如烧录，编译，压缩等）也发布成了组件。可以通过如下命令方式进行安装，执行完该命令后，系统会自动将开发依赖的工具下载安装，且这些组件只需全局安装一次。
-
-```
-hpm i -g @ohos/llvm
-hpm i -g @ohos/ninja
-hpm i -g @ohos/gn
-hpm i -g @ohos/hc_gen
-hpm i -g @ohos/sysroot
-```
-
-这是一组开发工具的组件包（如包含gn，ninja等工具），有了这些开发态的组件，就可以进行常规的源码组件的开发了。

-# 概述<a name="ZH-CN_TOPIC_0000001051452100"></a>
-
-本章节将简要介绍如何开发OpenHarmony组件和发行版，并通过命令行工具方式完成组件创建、开发、编译、烧录、调试等开发过程。
-
--   一个组件（bundle）通常和一个代码仓库对应，在代码的基础上增加bundle.json、README文件、LICENSE描述文件。
--   一个发行版（distribution）是由多个组件构成的。发行版中集合了一个完整系统的各种组件（如驱动、内核、框架、应用），可以用于设备的烧录。

-
-本文档将介绍组件的基本概念以及如何按照规范定义组件。
-
-## 定义<a name="section177563344911"></a>
-
-OpenHarmony软件以组件\(bundle\)作为基本单元，从系统角度看，凡是运行在OpenHarmony上的软件都可以定义为组件；一般来讲，根据组件的应用范围，可以分为：
-
--   板级组件：如board、arch、mcu这些与设备硬件相关的组件。
--   系统组件：一组独立功能的集合，如内核、文件系统、框架等。
--   应用组件：直接面向用户提供服务的应用\(如wifi\_iot，ip\_camera\)。
-
-从形式上看，组件是为复用而生，一切可以复用的模块都可以定义为组件，可以分为：
-
--   源代码
--   二进制
--   代码片段
--   发行版
-
-## 组件划分原则<a name="section2487162541016"></a>
-
-原则上应尽可能划分为细颗粒度的组件，以满足最大限度的复用。主要考虑以下几点：
-
--   独立性：组件的功能应该相对独立，支持独立编译，可以单独对外提供接口和服务；
--   耦合性：如果组件必须依赖其他的组件，才能对外提供服务，应考虑和被依赖的组件合并为一个组件。
--   相关性：如果一组组件共同完成一项功能，且没有被其他组件依赖，未来也没有被依赖的可能，则可以考虑合并为一个组件。
-
-## 组件依赖<a name="section185955409107"></a>
-
-组件的依赖关系分为两种：必选依赖和可选依赖。
-
--   必选依赖：是指组件A在完成某个功能时，必须引入组件B，调用B的接口或服务配合才能完成。称B为A的必选依赖。
--   可选依赖：是在组件A在完成某个功能时，可以引入组件C，也可以引入组件D。C和D可以相互替换，称C和D为A的可选依赖。

-## linux服务器<a name="section20979554791"></a>
-
-准备一台装有Ubuntu 16.04 及以上 64 位系统的linux服务器（hpm是支持windows的，但是目前OpenHarmony开源的Hi3861、Hi3516、Hi3518三个解决方案都只支持Ubuntu）。
-
-将linux shell改为bash：
-
-```
-ls -l $(which sh)
-# 如果指向的不是bash，则按以下方式修改：
-# 方法一：执行以下命令，然后选择no
-dpkg-reconfigure dash
-# 方法二：先删除sh，再重新创建软连接
-rm -f /bin/sh
-ln -s bash /bin/sh
-```
-
-## 安装Node.js<a name="section9954105413153"></a>
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->如果配置的源的nodejs版本太低，可以执行以下语句后再执行apt-get install：
->```
->curl -L https://deb.nodesource.com/setup_12.x | bash
->```
-
-推荐安装 Node.js 12.x （包含 npm 6.14.4）或更高版本（推荐 12.13.0+）：
-
-```
-sudo apt-get install nodejs
-sudo apt-get install npm
-```
-
-查看版本：
-
-```
-node --version  # 查看nodejs版本
-npm --version   # 查看npm版本
-```
-
-## 安装HPM<a name="section15937194904819"></a>
-
-通过 Node.js 自带的 npm（使用默认的源 https://registry.npmjs.org/ ）安装 hpm-cli 命令行工具：
-
-```
-npm install -g @ohos/hpm-cli
-```
-
-安装完hpm-cli命令行工具后，执行以下命令可以查看hpm配置：
-
-```
-hpm config
-```
-
-上述命令执行后将会显示hpm的默认配置，您可以根据自己的喜好对默认配置进行修改，以下是hpm的常用配置：
-
-```
-registry = https://hpm.harmonyos.com              # hpm注册中心地址，下载组件必须
-strictSsl = true                                  # 通过https连接时，是否需要校验证书
-http_proxy = http://your-proxy-server:port        # 配置HTTP代理
-https_proxy = http://your-proxy-server:port       # 配置HTTPS代理
-```
-
-hpm-cli的命令介绍可以参考：[hpm操作命令](组件管理.md)
-
-## 安装python环境<a name="section1621819180417"></a>

-# 环境变量说明<a name="ZH-CN_TOPIC_0000001054807267"></a>
-
-组件在编译的过程中需要依赖系统提供的环境变量来自定义输出，链接所需二进制文件等等。这里提出的环境变量均指根据需求把所需变量注入脚本执行的上下文中。所以在脚本中可以直接获取到变量的值。下面介绍当前系统存在的几种环境变量。全局变量
-
-全局变量由bundle.json中的envs属性来定义。整个组件中的依赖都可以获取到全局变量定义的值。
-
-```
-{
-    "envs": {
-        "compileEnv": "arm"
-    }
-}
-```
-
-不同组件在引入依赖的过程中可以传入不同的参数，从而使依赖的编译可以满足当前组件的需求。依赖中定义的参数可以在对应依赖脚本执行的上下文中获取到。
-
-```
-{
-    "dependencies": {
-        "my-bundle": {
-            "version": "1.0.0",
-            "mode": "debug"
-        }
-    }
-}
-```
-
-组件在链接二进制文件的时候，需要知道二进制文件在依赖中的路径，所以依赖的路径会作为环境变量传入编译组件中。
-
-传入的环境变量的格式为DEP\_BundleName，BundleName为依赖的名称，例如 DEP\_first\_bundle。
-
-依赖中可以定义标签，对引入的依赖进行分组。在脚本中可以根据标签，获得这一组依赖的路径。定义的标签以\#开头，具体定义的方式为：
-
-```
-{
-    "dependencies": {
-        "#tool": {
-            "first-bundle": "1.0.0",
-            "second-bundle": "1.0.0"
-        },
-        "#drivers": {
-            "xx-bundle": "1.0.0",
-            "yy-bundle": "1.0.0"
-        }
-    }
-}
-```
-
-系统中存在两个固定环境变量：
-
--   DEP\_OHOS\_BUNDLES：表示ohos\_bundles文件夹所在的路径。
--   DEP\_BUNDLE\_BASE：表示最外层组件的路径。

-## 创建OpenHarmony组件<a name="section1976410130540"></a>
-
-创建OpenHarmony组件有如下几种方式：
-
--   从头开发一个全新的组件。
--   将一个现有的非组件的代码改造成组件。
-
--   hpm提供了一些组件模板方便快速创建组件。
-
-## 新建组件<a name="section717481119145"></a>
-
-通常情况下，[HPM网站](https://hpm.harmonyOS.com)上能找到您开发常用的组件，如果现有的组件不能完全满足开发，这时可以自己动手开发一个组件。
-
-如果您愿意，可以将组件发布到HPM的仓库中供其他用户使用。假设要在D:/source目录下新建一个全新的组件my-bundle：
-
-可以使用hpm init 创建该组件的脚手架代码，例如，进入D:/source目录，执行如下命令：
-
-```
-hpm init -t default  -d demo my-bundle
-```
-
-会在 source 目录下生成如下文件：
-
-```
-mybundle
-├── bundle.json      # 组件元数据描述文件
-├── example          # 测试组件功能的示例
-│   └── main.c
-├── include            # 组件的内部头文件
-│   └── mybundle.h
-├── README.md        # 组件的简要说明
-└── src              # 组件的源代码
-     └─ mybundle.c
-```
-
-接下来根据您的业务需要，实现组件内部的功能代码，完成代码开发后，通过git将代码（包括bundle.json文件）提交到组件代码托管仓库中（如gitee）。
-
-## 改造组件<a name="section102861955201410"></a>
-
-如果您已经有了代码，只是还不满足OpenHarmony的组件结构，需要改造成为hpm的组件包，只需要在当前要改造的代码目录下（例如mybundle2），执行如下命令，会提示您输入组件名称和版本。
-
-```
-hpm init
-```
-
-1.  输入名称后回车（如mybundle2）。
-2.  输入版本后（如1.0.0）回车，在当前组件目录下会生成一个bundle.json文件。
-3.  打开bundle.json文件再添加其他的描述，这时候他已经是一个具备可发布的组件了。
-
-    ```
-    $ hpm init
-    Your bundle will be created in dirname E:\demo\mybundle2
-    ? bundle name mybundel2
-    ? version 1.0.0
-    Init finished!
-    ```
-
-
-1.  打开bundle.json文件修改其他信息（如作者，代码仓库，代码目录，命令脚本，依赖组件等），如下：
-
-    ```
-    {
-    "name": "mybundle2",
-    "version": "1.0.0",
-    "publishAs": "source",
-    "dirs":{
-    ".":[
-    "README.md"
-        ],
-    "src":[
-    "test.c"
-        ],
-    "header":[
-    "header/test.h"
-        ],    
-    "src/common":[
-    "src/common/foobar.txt"
-        ]
-      },
-    "scripts": {
-    "build": "make -${args}"
-      },
-    "dependencies": {
-    "@ohos/cjson": "^1.0.0",
-    "@ohos/": "^1.2.0"
-      }
-    }
-    ```

-## 从模板创建组件<a name="section15882846181510"></a>
-
-hpm 除了提供了默认模板 default和simple两个简单的模板之外，其他模板均存储在服务器端。
-
-可以使用命令hpm search -t template 从服务器端搜索模板。
-
-![](figures/zh-cn_image_0000001051452177.png)
-
-根据description简要中的描述，找到适合的模板，基于模板可以快速创建一个组件的脚手架，执行如下初始化命令（指定-t -d 参数）。
-
-```
-hpm init -t {templatename} -d dir name
-```
-
--   \{templatename\} ：指的是模板名称。
--   -d 后面的参数dir：是要创建的组件所存放的路径。
--   name：为要创建的组件名称。
-
-## 编译组件<a name="section136732148541"></a>
-
-完成代码开发后，需要对组件进行编译。hpm提供了命令集成的能力，您可以选择任意的适合项目的编译工具（如make，gcc，gn等等）。只需在当前项目的bundle.json文件中定义scripts脚本中的build命令，就可以通过执行hpm build执行编译。
-
-## 定义编译脚本<a name="section10274147111610"></a>
-
-以编译一个app目录下helloworld可执行文件为例：
-
-```
-app
-├── BUILD.gn
-├── include
-│   └── helloworld.h
-└── src
-    └── helloworld.c
-```
-
-在helloworld.c同级目录下新建一个BUILD.gn
-
-```
-touch BUILD.gn
-vim BUILD.gn
-```
-
-以下是BUILD.gn的样例，仅供参考
-
-```
-executable("hello_world") {
-    sources = [
-        "src/helloworld.c"
-    ]
-
-    include_dirs = [
-        "include"
-    ]
-}
-```
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   “executable”是gn内置模板，可以用“gn help executable ”查看使用方法。
->-   “sources ”是源码路径，“include\_dirs ”是头文件路径。
-
-## 执行编译<a name="section879301916172"></a>
-
-在当前文件夹下，执行编译命令：
-
-```
-hpm build
-```
-
-在完成一系列的编译动作后，显示build succeed。检查编译的输出结果：
-
-![](figures/zh-cn_image_0000001051770876.png)
-
-## 定义发行版<a name="section413216495619"></a>
-
-发行版是将一组组件组合起来的，编译生成可以运行的OpenHarmony解决方案，里面包含了较多依赖的组件，以及以脚本形式描述如何完整编译、链接这些组件。
-
-## 定义脚本<a name="section11503171219190"></a>
-
-bundle.json中定义
-
-```
-{
-"name": "my_dist",
-"version": "1.0.0",
-"publishAs": "distribution",
-"scripts": {
-"dist": "make -${args}"
-  },
-"base": {
-"name": "dist-bundle",
-"version": "1.0.0"
-  },
-"envs": {
-"args": "x86"
-  },
-"dependencies": {
-}
-}
-```
-
-## 发行<a name="section4694125521912"></a>
-
-在当前发行版根目录下，执行如下命令。
-
-```
-hpm dist
-```
-
-hpm-cli工具会自动执行编译，打包操作，将根据scripts定义的dist脚本生成镜像文件，如：
-
-```
-out
-|-xxdist.img
-|-xx.file
-```
-
-## 烧录<a name="section1746331545413"></a>
-
-发行版的编译结果可以烧录到设备中运行，例如使用hiburn工具进行烧录。在发行版的bundle.json文件配置烧录参数。
-
-```
-"scripts": {
-"flash": "{$DEP_HIBURN}/hiburn"
-},
-```
-
-配置烧录相关的参数（参考烧录工具的说明进行配置）。
-
-```
-hpm run flash
-```
-
-## 运行调试<a name="section6742131615549"></a>
-
-将发行版的镜像烧录到设备中后，就可以启动运行调试了，由于运行调试和具体的开发板和IDE调试工具相关，此处不再详细描述。

-
-名称需要为全小写字母，中间可以使用中划线或者下划线分隔。比如 "bundle", "my\_bundle"。
-
-版本号的格式为 "主版本号.次版本号.修订号" 或 "主版本号.次版本号.修订号-先行版本号"，比如 "1.0.0"， "1.0.0-beta"，详细规格可以参考  [https://semver.org](https://semver.org/)。
-
-## 版本发布<a name="section43401320171420"></a>
-
-为了使组件能被其他开发者使用，组件需要上传到远端仓库。组件上传使用如下命令：
-
-```
-hpm publish
-```
-
-命令执行以后，系统会对的整个依赖关系进行检查，下载缺失依赖组件。依赖检查完成后，如果发布类型为binary，系统会对整个组件进行编译，生成二进制文件，然后打包上传。如果使其他上传类型，则直接根据定义的打包规则进行打包，然后上传。
-
-注意：发布组件需要用户账号登录，需要先拥有hpm的系统账号后，并注册组织，申请组织认证通过后，才拥有发布的权限。

-
-生成基础bundle.json以后，需要继续添加组件依赖来实现更复杂的功能。此时需要知道所依赖组件的名称和版本号，并且把它们定义在bundle.json里面的dependencies字段中。
-
-```
-{
-    "name": "my-bundle",
-    "version": "1.0.0",
-    "dependencies": {
-        "net": "1.0.0"
-    }
-}
-```
-
-上述示例中，my-bundle组件依赖于net 1.0.0组件。在全局安装了 hpm CLI 工具之后，执行如下命令可以从远端仓库获取到依赖：
-
-```
-hpm install 
-```
-
-依赖获取以后，会保存到当前组件根目录下到ohos\_bundles文件夹中。组件以及依赖之间会形成一个依赖关系的树状结构。全局安装了 hpm CLI 工具之后，在组件根目录下执行如下命令：
-
-```
-username@server MINGW64 /f/showcase/demo/demo
-$ hpm list
-+--demo@1.0.0
-| +--@huawei/media@1.0.2
-| +--@demo/sport_hi3518ev300_liteos_a@1.0.0

-
-还可以使用图的形式，来查看当前组件的依赖关系，执行如下命令：
-
-```
-hpm dependencies
-```
-
-在当前目录下会生成deps\_visual文件夹，里面包含两个文件，deps.html 和 deps-data.js。在浏览器中打开 deps.html 文件，就可以看到依赖关系的图形化展示\(如下图\)。
-
-根据不同的依赖类型，图形结点呈现出不同的颜色。鼠标悬浮在结点上，可以查看当前结点的状态。

-# GPIO使用实例<a name="ZH-CN_TOPIC_0000001052777597"></a>
-
-本实例程序中，我们将测试一个GPIO管脚的中断触发：为管脚设置中断服务函数，触发方式为边沿触发，然后通过交替写高低电平到管脚，产生电平波动，制造触发条件，观察中断服务函数的执行。
-
-首先需要选取一个空闲的GPIO管脚，本例程基于Hi3516DV300某开发板，GPIO管脚选择GPIO10\_3，换算成GPIO号为83。
-
-读者可以根据自己使用的开发板，参考其原理图，选择一个空闲的GPIO管脚即可。

-## 确定GPIO管脚号<a name="section135943361443"></a>
-
-不同SOC芯片由于其GPIO控制器型号、参数、以及控制器驱动的不同，GPIO管脚号的换算方式不一样。
-
--   Hi3516DV300
-
-    控制器管理12组GPIO管脚，每组8个。
-
-    GPIO号 = GPIO组索引 \(0\~11\) \* 每组GPIO管脚数\(8\) + 组内偏移
-
-    举例：GPIO10\_3的GPIO号 = 10 \* 8 + 3 = 83
-
--   Hi3518EV300
-
-    控制器管理10组GPIO管脚，每组10个。
-
-    GPIO号 = GPIO组索引 \(0\~9\) \* 每组GPIO管脚数\(10\) + 组内偏移
-
-    举例：GPIO7\_3的GPIO管脚号 = 7 \* 10 + 3 = 73

-## 简介<a name="section15318165672215"></a>
-
-GPIO（General-purpose input/output）即通用型输入输出。通常，GPIO控制器通过分组的方式管理所有GPIO管脚，每组GPIO有一个或多个寄存器与之关联，通过读写寄存器完成对GPIO管脚的操作。
-
-GPIO接口定义了操作GPIO管脚的标准方法集合，包括：
-
--   设置管脚方向： 方向可以是输入或者输出\(暂不支持高阻态\)
-
--   读写管脚电平值： 电平值可以是低电平或高电平
--   设置管脚中断服务函数：设置一个管脚的中断响应函数，以及中断触发方式
--   使能和禁止管脚中断：禁止或使能管脚中断

-# I2C使用实例<a name="ZH-CN_TOPIC_0000001052218252"></a>
-
-本例程以操作开发板上的I2C设备为例，详细展示I2C接口的完整使用流程。
-
-本例拟对Hi3516DV300某开发板上TouchPad设备进行简单的寄存器读写访问，基本硬件信息如下：
-
--   SOC：hi3516dv300。
-
--   Touch IC：I2C地址为0x38, IC内部寄存器位宽为1字节。
-
--   原理图信息：TouchPad设备挂接在3号I2C控制器下；IC的复位管脚为3号GPIO。
-
-本例程首先对Touch IC进行复位操作（开发板上电默认会给TouchIC供电，本例程不考虑供电），然后对其内部寄存器进行随机读写，测试I2C通路是否正常。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->本例程重点在于展示I2C设备访问流程，并验证I2C通路，所以对于设备寄存器读写值不做关注，读写寄存器导致的行为由设备自身决定。

--   I2C以主从方式工作，通常有一个主设备和一个或者多个从设备，主从设备通过SDA\(SerialData\)串行数据线以及SCL\(SerialClock\)串行时钟线两根线相连，如[图1 ](#fig1135561232714)所示。
-
--   I2C数据的传输必须以一个起始信号作为开始条件，以一个结束信号作为传输的停止条件。数据传输以字节为单位，高位在前，逐个bit进行传输。
--   I2C总线上的每一个设备都可以作为主设备或者从设备，而且每一个设备都会对应一个唯一的地址，当主设备需要和某一个从设备通信时，通过广播的方式，将从设备地址写到总线上，如果某个从设备符合此地址，将会发出应答信号，建立传输。
-
--   I2C接口定义了完成I2C传输的通用方法集合，包括：
-
-    -   I2C控制器管理:  打开或关闭I2C控制器
-    -   I2C消息传输：通过消息传输结构体数组进行自定义传输

-LCD（Liquid Crystal Display）液晶显示驱动，对LCD进行上电，并通过接口初始化LCD内部寄存器，使LCD正常工作。Display驱动模型基于HDF（ Hardware Driver Foundation）[驱动框架](HDF开发概述.md)开发，实现跨OS、跨平台，为LCD硬件提供上下电功能、发送初始化序列功能，使LCD进入正常的工作模式，显示芯片平台侧的图像数据，基于HDF驱动框架的Display驱动模型如[图1](#fig69138814229)。

--   **Display驱动模型介绍**
-
-    Display驱动模型主要由平台驱动层、芯片平台适配层、LCD器件驱动层三部分组成。驱动模型基于HDF驱动框架开发，通过Platform层和OSAL层提供的接口，屏蔽内核形态的差异，使得器件驱动可以便利的迁移到不同OS及芯片平台。模型向上对接Display公共hal层，支撑HDI接口的实现，通过Display-HDI（Hardware Display Interface）对图形服务提供各类驱动能力接口。
-
-    （1）Display平台驱动层：通过HDF提供的IOService数据通道，与公共Hal层对接，集中接收并处理各类上层调用指令；
-
-    （2）SOC平台驱动适配层：借助此SOC适配层，实现Display驱动和SOC侧驱动解耦，主要完成芯片平台相关的参数配置，并传递平台驱动层的调用到器件驱动层；
-
-    （3）LCD器件驱动层：在器件驱动层中，主要实现和器件自身强相关的驱动适配接口，例如发送初始化序列、上下电、背光设置等。
-
-    基于Display驱动模型开发LCD驱动，可以借助平台提供的各种能力及接口，较大程度的降低器件驱动的开发周期和难度，提升开发效率。

-## 接口说明<a name="section20280192712120"></a>
-
-LCD接口通常可分为MIPI DSI接口、TTL接口和LVDS接口，常用的是MIPI DSI接口和TTL接口，下面对常用的MIPI DSI接口和TTL接口作简要介绍。
-
--   MIPI DSI接口
-
-    **图 2**  MIPI DSI接口<a name="fig6936451331"></a>  
-    ![](figures/MIPI-DSI接口.png "MIPI-DSI接口")
-
-    MIPI DSI接口是MIPI（移动行业处理器接口）联盟定义的显示接口，主要用于移动终端显示屏接口，接口数据传输遵循MIPI协议，MIPI DSI接口为数据接口，传输图像数据，通常情况下MIPI DSI接口的控制信息以MIPI包形式通过MIPI DSI接口发送到对端IC，不需要额外的外设接口。
-
--   TTL接口
-
-    **图 3**  TTL接口<a name="fig141611855635"></a>  
-    ![](figures/TTL接口.png "TTL接口")
-
-    TTL（Transistor Transistor Logic）即晶体管-晶体管逻辑，TTL电平信号由TTL器件产生，TTL器件是数字集成电路的一大门类，它采用双极型工艺制造，具有高速度、低功耗和品种多等特点。
-
-    TTL接口是并行方式传输数据的接口，有数据信号、时钟信号和控制信号（行同步、帧同步、数据有效信号等），在控制信号控制下完成数据传输。通常TTL接口的LCD，内部寄存器读写需要额外的外设接口，比如SPI接口、I2C接口等。

-## 简介<a name="section1369320102013"></a>
-
--   DSI（Display Serial Interface）是由移动行业处理器接口联盟（Mobile Industry Processor Interface \(MIPI\) Alliance）制定的规范，旨在降低移动设备中显示控制器的成本。它以串行的方式发送像素数据或指令给外设\(通常是LCD或者类似的显示设备\)，或从外设中读取状态信息或像素信息；它定义了主机、图像数据源和目标设备之间的串行总线和通信协议。
-
--   MIPI-DSI具备高速模式和低速模式两种工作模式，全部数据通道都可以用于单向的高速传输，但只有第一个数据通道才可用于低速双向传输，从属端的状态信息、像素等是通过该数据通道返回。时钟通道专用于在高速传输数据的过程中传输同步时钟信号。
-    -   图1显示了简化的DSI接口。从概念上看，符合DSI的接口与基于DBI-2和DPI-2标准的接口具有相同的功能。它向外围设备传输像素或命令数据，并且可以从外围设备读取状态或像素信息。主要区别在于，DSI对所有像素数据、命令和事件进行序列化，而在传统接口中，这些像素数据、命令和事件通常需要附加控制信号才能在并行数据总线上传输。

-本实例提供RTC接口的完整使用流程：
-
-1.  系统启动，驱动管理模块会识别系统当前的RTC器件;
-2.  驱动管理模块完成RTC设备的初始化和设备创建；
-3.  用户通过不同API，对该RTC设备进行对应的操作；
-4.  关闭RTC设备，释放设备资源。
-
-示例如下：
-
-```

-## 简介<a name="section104842041574"></a>
-
-RTC\(real-time clock\)为操作系统中的实时时钟设备，为操作系统提供精准的实时时间和定时报警功能。当设备下电后，通过外置电池供电，RTC继续记录操作系统时间；设备上电后，RTC提供实时时钟给操作系统，确保断电后系统时间的连续性。

--   SDIO是安全数字输入输出接口（Secure Digital Input and Output）的缩写，是从SD内存卡接口的基础上演化出来的一种外设接口。SDIO接口兼容以前的SD内存卡，并且可以连接支持SDIO接口的设备。
--   SDIO的应用比较广泛，目前，有许多手机都支持SDIO功能，并且很多SDIO外设也被开发出来，使得手机外接外设更加容易。常见的SDIO外设有WLAN、GPS、CAMERA、蓝牙等。
--   SDIO总线有两端，其中一端是主机端（HOST），另一端是设备端（DEVICE）。所有的通信都是由HOST端发出命令开始的，在DEVICE端只要能解析HOST的命令，就可以同HOST进行通信了。SDIO的HOST可以连接多个DEVICE，如下图所示：
-
-    -   CLK信号：HOST给DEVICE的时钟信号。
-    -   VDD信号：电源信号。
-    -   VSS信号：Ground信号。
-    -   D0-3信号：4条数据线，其中，DAT1信号线复用为中断线，在1BIT模式下DAT0用来传输数据，在4BIT模式下DAT0-DAT3用来传输数据。
-    -   CMD信号：用于HOST发送命令和DEVICE回复响应。
-

-
--   SDIO接口定义了操作SDIO的通用方法集合，包括打开/关闭SDIO控制器、独占/释放HOST、使能/去使能设备、申请/释放中断、读写、获取/设置公共信息等。

-## 简介<a name="section9202632114011"></a>
-
--   SPI是串行外设接口（Serial Peripheral Interface）的缩写，是一种高速的，全双工，同步的通信总线。
--   SPI是由Motorola公司开发，用于在主设备和从设备之间进行通信，常用于与闪存、实时时钟、传感器以及模数转换器等进行通信。
--   SPI以主从方式工作，通常有一个主设备和一个或者多个从设备。主设备和从设备之间一般用4根线相连，它们分别是：
-    -   SCLK – 时钟信号，由主设备产生；
-    -   MOSI – 主设备数据输出，从设备数据输入；
-    -   MISO – 主设备数据输入，从设备数据输出；
-    -   CS – 片选，从设备使能信号，由主设备控制。
-
-
--   一个主设备和两个从设备的连接示意图如[图1](#fig15227181812587)所示，Device A和Device B共享主设备的SCLK、MISO和MOSI三根引脚，Device A的片选CS0连接主设备的CS0，Device B的片选CS1连接主设备的CS1。
-

-
-
-![](figures/zh-cn_image_0000001054142582.png)
-
--   SPI通信通常由主设备发起，通过以下步骤完成一次通信：
-
-1.  通过CS选中要通信的从设备，在任意时刻，一个主设备上最多只能有一个从设备被选中。
-2.  通过SCLK给选中的从设备提供时钟信号。
-3.  基于SCLK时钟信号，主设备数据通过MOSI发送给从设备，同时通过MISO接收从设备发送的数据，完成通信。
-
--   根据SCLK时钟信号的CPOL（Clock Polarity，时钟极性）和CPHA（Clock Phase，时钟相位）的不同组合，SPI有以下四种工作模式：
-    -   CPOL=0，CPHA=0 时钟信号idle状态为低电平，第一个时钟边沿采样数据。
-    -   CPOL=0，CPHA=1 时钟信号idle状态为低电平，第二个时钟边沿采样数据。
-    -   CPOL=1，CPHA=0 时钟信号idle状态为高电平，第一个时钟边沿采样数据。
-    -   CPOL=1，CPHA=1 时钟信号idle状态为高电平，第二个时钟边沿采样数据。
-
-
--   SPI接口定义了操作SPI设备的通用方法集合，包括：
-    -   SPI设备句柄获取和释放。
-    -   SPI读写:  从SPI设备读取或写入指定长度数据。
-    -   SPI自定义传输：通过消息传输结构体执行任意读写组合过程。
-    -   SPI设备配置：获取和设置SPI设备属性。

-
-Input驱动模型是基于HDF框架、Platform接口和OSAL接口开发，不区分操作系统和芯片平台，为touchscreen等输入器件提供统一的驱动开发架构。
-
--   如下以touchscreen器件驱动为例，说明input驱动模型的完整加载流程：
-
-    （1）设备描述配置：由开发者参考已有模板进行设备描述配置，包括驱动加载顺序、板级硬件信息、器件私有数据信息等。
-
-    （2）加载input设备管理驱动：input设备管理驱动由HDF驱动加载，完成设备manager的创建并对其初始化。
-
-    （3）加载平台驱动：平台驱动由HDF框架加载，主要完成板级配置解析及硬件初始化，并提供器件注册接口。
-
-    （4）加载器件驱动：器件驱动也由HDF框架加载，完成器件设备的实例化，包括器件私有配置解析和平台预留的差异化接口适配。
-
-    （5）器件设备向平台驱动注册：将实例化的器件设备向平台驱动注册，实现设备和驱动的绑定，并完成中断注册、上下电等器件初始化工作。
-
-    （6）input设备注册：在器件初始化完成后，实例化input设备，并将其注册到input manager进行管理。
-
-
-## 开发步骤<a name="section1255740132616"></a>
-
-1.  设备描述配置
-
-    目前Input驱动基于HDF驱动框架编写，驱动的加载启动由HDF驱动管理框架统一处理。首先需要在对应的配置文件中，将驱动信息注册进去，如是否加载、加载优先级，此后HDF驱动框架会逐一启动注册过的驱动模块。驱动的相关配置请参考[HDF驱动框架配置指导](驱动开发.md#section1969312275533)。
-
-2.  板级配置及Touchscreen器件私有配置
-
-    配置对应的IO管脚功能，例如对单板上为touchscreen设计预留的I2C Pin脚，需设置对应的寄存器，使其选择I2C的通信功能。
-
-3.  实现器件差异化适配接口
-
-    根据硬件单板设计的通信接口，使用Platform接口层提供的管脚操作接口配置对应的复位管脚、中断管脚以及电源操作，对于GPIO的操作，可参考[GPIO操作接口指导](GPIO使用指导.md)

--   **Touchscreen驱动主要任务**
-
-    Touchscreen驱动用于驱动触摸屏使其正常工作，该驱动主要完成如下工作：对触摸屏驱动IC进行上电、配置硬件管脚并初始化其状态、注册中断、配置通信接口（I2C或SPI）、设定input相关配置、下载及更新固件等操作。
-
-
--   **Touchscreen驱动层次说明**
-
-    本节主要介绍基于input驱动模型开发touchscreen器件驱动，其整体的框架模型如[图1](#fig6251184817261)。
-
-    Input驱动模型基于HDF驱动框架、PLATFORM接口、OSAL接口进行开发，向上对接规范化的驱动接口HDI（Hardware Driver Interface）层，通过Input-HDI层对外提供硬件能力，即上层input service可以通过HDI接口层获取相应的驱动能力，进而操控touchscreen等输入设备。
-

-
--   **Input驱动模型介绍**
-
-    Input驱动模型核心部分由设备管理层、公共驱动层、器件驱动层组成。器件产生的数据借助平台数据通道能力从内核传递到用户态，驱动模型通过配置文件适配不同器件及硬件平台，提高开发者的器件驱动开发效率。如下部分为模型各部分的说明：
-
-    （1）input设备管理：为各类输入设备驱动提供input设备的注册、注销接口，同时统一管理input设备列表；
-
-    （2）input平台驱动：指各类input设备的公共抽象驱动（例如触摸屏的公共驱动），负责对板级硬件进行初始化、硬件中断处理、向manager注册input设备等；
-
-    （3）input器件驱动：指各器件厂家的差异化驱动，通过适配平台驱动预留的差异化接口，实现器件驱动开发量最小化；
-
-    （4）input数据通道：提供一套通用的数据上报通道，各类别的input设备驱动均可用此通道上报input事件；
-
-    （5）input配置解析：负责对input设备的板级配置及器件私有配置进行解析及管理。
-
-
--   **基于HDF驱动框架开发器件驱动的优势**
-
-    在HDF（Hardware Driver Foundation）[驱动管理框架](驱动开发.md)的基础上，input驱动模型调用OSAL接口层和Platfom接口层提供的基础接口进行开发，包括bus通信接口、操作系统原生接口（memory、lock、thread、timer等）。由于OSAL接口和Platform接口屏蔽了芯片平台差异，所以基于input驱动模型实现的touchscreen驱动可以进行跨平台、跨OS迁移，以便逐步实现驱动的一次开发，多端部署。
-
-
-## 接口说明<a name="section10542625172618"></a>
-
-Touchscreen器件的硬件接口相对简单，根据PIN脚的属性，可以简单分为如下三类:
-
--   电源接口
--   IO控制接口
--   通信接口
-
-**图 2**  Touchscreen器件常用管脚<a name="fig1290384314416"></a>  
-![](figures/Touchscreen器件常用管脚.png "Touchscreen器件常用管脚")
-
-如上图所示的三类接口，分别做简要说明如下：
-
-1.  **电源接口**
-    -   LDO\_1P8：1.8v数字电路
-    -   LDO\_3P3：3.3v模拟电路
-
-        通常情况下，touchscreen驱动IC和LCD驱动IC是相互分离的，这种情况下，touchscreen驱动IC一般同时需要1.8v和3.3v两路供电。随着芯片演进，业内已有touchscreen驱动IC和LCD驱动IC集成在一颗IC中的芯片案例，对touchscreen而言，只需要关注1.8v供电即可，其内部需要的3.3v电源，会在驱动IC内部从LCD的VSP电源（典型值5.5V）中分出来。
-
-
-2.  **IO控制接口**
-    -   Reset：reset管脚，用于在系统休眠、唤醒时，由主机侧对驱动IC进行复位操作。
-    -   INT：中断管脚，需要在驱动初始化时，配置为输入上拉状态。在驱动IC检测到外部触摸信号后，通过操作中断管脚来触发中断，器件驱动则会在中断处理函数中进行报点数据读取等操作。
-
-3.  **通信接口**
-    -   I2C：由于touchscreen的报点数据量相对较少，所以一般选用I2C方式传输数据。I2C的具体协议及对应操作接口，可以参考Platform接口层中的[“I2C”使用指南](I2C使用指导.md)。
-    -   SPI：部分厂商，由于需要传递的数据不止报点坐标，而是需要获取基础容值，数据量较大，所以会选用SPI通信方式。SPI的具体协议及对应操作接口，可以参考Platform接口层中的[“SPI” 使用指南](SPI使用指导.md)。

--   UART是通用异步收发传输器（Universal Asynchronous Receiver/Transmitter）的缩写，是通用串行数据总线，用于异步通信。该总线双向通信，可以实现全双工传输。
--   UART应用比较广泛，常用于输出打印信息，也可以外接各种模块，如GPS、蓝牙等。
--   两个UART设备的连接示意图如下，UART与其他模块一般用2线（图1）或4线（图2）相连，它们分别是：
-    -   TX：发送数据端，和对端的RX相连；
-    -   RX：接收数据端，和对端的TX相连；
-    -   RTS：发送请求信号，用于指示本设备是否准备好，可接受数据，和对端CTS相连；
-    -   CTS：允许发送信号，用于判断是否可以向对端发送数据，和对端RTS相连；

-
--   UART通信之前，收发双方需要约定好一些参数：波特率、数据格式（起始位、数据位、校验位、停止位）等。通信过程中，UART通过TX发送给对端数据，通过RX接收对端发送的数据。当UART接收缓存达到预定的门限值时，RTS变为不可发送数据，对端的CTS检测到不可发送数据，则停止发送数据。
--   UART接口定义了操作UART端口的通用方法集合，包括获取、释放设备句柄、读写数据、获取和设置波特率、获取和设置设备属性。

-## 简介<a name="section23087361515"></a>
-
-WLAN是基于HDF（Hardware Driver Foundation）驱动框架开发的模块，该模块可实现跨操作系统迁移，自适应器件差异，模块化拼装编译等功能。各WLAN厂商驱动开发人员可根据WLAN模块提供的向下统一接口适配各自的驱动代码，实现如下能力：建立/关闭WLAN热点、扫描、关联WLAN热点等；对HDI层向上提供能力如下：设置MAC地址、设置发射功率、获取设备的MAC地址等。[WLAN模块框架图](#fig967034316227)如下：

-## WLAN驱动接口架构<a name="section1533192516212"></a>
-
-WLAN模块有三部分对外开放的API接口，如[下图2](#fig15016395217)所示：
-
-1. 对HDI层提供的能力接口。
-
-2. 驱动直接调用WLAN模块能力接口。
-
-3. 提供给各厂商实现的能力接口。

+## 驱动模型介绍<a name="section157425168112"></a>
+
+HDF框架以组件化的驱动模型作为核心设计思路，为开发者提供更精细化的驱动管理，让驱动开发和部署更加规范。HDF框架将一类设备驱动放在同一个host里面，开发者也可以将驱动功能分层独立开发和部署，支持一个驱动多个node，HDF驱动模型如下图所示：
+
+**图 1**  HDF驱动模型<a name="fig5487113011526"></a>  
+
+
+![](figure/zh-cn_image_0000001054564784.png)
+
+## 驱动开发步骤<a name="section1969312275533"></a>
+
+基于HDF框架进行驱动的开发主要分为两个部分，驱动实现和驱动配置，详细开发流程如下所示：
+
+1.  <a name="li35182436435"></a>驱动实现
+
+    驱动实现包含驱动业务代码和驱动入口注册，具体写法如下：
+
+    -   驱动业务代码
+
+        ```
+        #include "hdf_device_desc.h"  // HDF框架对驱动开放相关能力接口的头文件
+        #include "hdf_log.h"          // HDF 框架提供的日志接口头文件
+        
+        #define HDF_LOG_TAG "sample_driver"   // 打印日志所包含的标签，如果不定义则用默认定义的HDF_TAG标签
+        
+        //驱动对外提供的服务能力，将相关的服务接口绑定到HDF框架
+        int32_t HdfSampleDriverBind(struct HdfDeviceObject *deviceObject)
+        {
+            HDF_LOGD("Sample driver bind success");
+            return 0;
+        }
+        
+        // 驱动自身业务初始的接口
+        int32_t HdfSampleDriverInit(struct HdfDeviceObject *deviceObject)
+        {
+            HDF_LOGD("Sample driver Init success");
+            return 0;
+        }
+        
+        // 驱动资源释放的接口
+        void HdfSampleDriverRelease(struct HdfDeviceObject *deviceObject)
+        {
+            HDF_LOGD("Sample driver release success");
+            return;
+        }
+        ```
+
+    -   驱动入口注册到HDF框架
+
+        ```
+        // 定义驱动入口的对象，必须为HdfDriverEntry（在hdf_device_desc.h中定义）类型的全局变量
+        struct HdfDriverEntry g_sampleDriverEntry = {
+            .moduleVersion = 1,
+            .moduleName = "sample_driver",
+            .Bind = HdfSampleDriverBind,
+            .Init = HdfSampleDriverInit,
+            .Release = HdfSampleDriverRelease,
+        };
+        
+        // 调用HDF_INIT将驱动入口注册到HDF框架中，在加载驱动时HDF框架会先调用Bind函数,再调用Init函数加载该驱动，当Init调用异常时，HDF框架会调用Release释放驱动资源并退出。
+        HDF_INIT(g_sampleDriverEntry);
+        ```
+
+
+2.  驱动编译
+    -   驱动代码的编译必须要使用HDF框架提供的Makefile模板进行编译。
+
+        ```
+        include $(LITEOSTOPDIR)/../../drivers/adapter/lite/khdf/lite.mk #导入hdf预定义内容，必需
+        MODULE_NAME :=    #生成的结果文件
+        LOCAL_INCLUDE :=  #本驱动的头文件目录
+        LOCAL_SRCS :=     #本驱动的源代码文件
+        LOCAL_CFLAGS ：=  #自定义的编译选项
+        include $(HDF_DRIVER) #导入模板makefile完成编译
+        ```
+
+    -   编译结果文件链接到内核镜像，添加到vendor目录下的hdf\_vendor.mk里面，示例如下：
+
+        ```
+        LITEOS_BASELIB +=  -lxxx  #链接生成的静态库
+        LIB_SUBDIRS    +=         #驱动代码Makefile的目录
+        ```
+
+
+3.  驱动配置
+
+    HDF使用HCS作为配置描述源码，HCS详细介绍参考[配置管理](drive-hdf-manage.md)介绍。
+
+    驱动配置包含两部分，HDF框架定义的驱动设备描述和驱动的私有配置信息，具体写法如下：
+
+    -   驱动设备描述（必选）
+
+        HDF框架加载驱动所需要的信息来源于HDF框架定义的驱动设备描述，因此基于HDF框架开发的驱动必须要在HDF框架定义的device\_info.hcs配置文件中添加对应的设备描述，驱动的设备描述填写如下所示：
+
+        ```
+        root {
+            device_info {
+                match_attr = "hdf_manager";
+                template host {       // host模板，继承该模板的节点（如下sample_host）如果使用模板中的默认值，则节点字段可以缺省
+                    hostName = "";
+                    priority = 100;
+                    template device {
+                        template deviceNode {
+                            policy = 0;
+                            priority = 100;
+                            preload = 0;
+                            permission = 0664;
+                            moduleName = "";
+                            serviceName = "";
+                            deviceMatchAttr = "";
+                        }
+                    }
+                }
+                sample_host :: host{
+                    hostName = "host0";    // host名称，host节点是用来存放某一类驱动的容器
+                    priority = 100;        // host启动优先级（0-200），值越大优先级越低，建议默认配100，优先级相同则不保证host的加载顺序
+                    device_sample :: device {        // sample设备节点
+                        device0 :: deviceNode {      // sample驱动的DeviceNode节点
+                            policy = 1;              // policy字段是驱动服务发布的策略，在驱动服务管理章节有详细介绍
+                            priority = 100;          // 驱动启动优先级（0-200），值越大优先级越低，建议默认配100，优先级相同则不保证device的加载顺序
+                            preload = 0;             // 驱动按需加载字段，在本章节最后的说明有详细介绍
+                            permission = 0664;       // 驱动创建设备节点权限
+                            moduleName = "sample_driver";   // 驱动名称，该字段的值必须和驱动入口结构的moduleName值一致
+                            serviceName = "sample_service";    // 驱动对外发布服务的名称，必须唯一
+                            deviceMatchAttr = "sample_config"; // 驱动私有数据匹配的关键字，必须和驱动私有数据配置表中的match_attr值相等
+                        }
+                    }
+                }
+            }
+        }
+        ```
+
+    -   驱动私有配置信息（可选）
+
+        如果驱动有私有配置，则可以添加一个驱动的配置文件，用来填写一些驱动的默认配置信息，HDF框架在加载驱动的时候，会将对应的配置信息获取并保存在HdfDeviceObject 中的property里面，通过Bind和Init（参考[驱动开发](#li35182436435)）传递给驱动，驱动的配置信息示例如下：
+
+        ```
+        root {
+            SampleDriverConfig {
+                sample_version = 1;
+                sample_bus = "I2C_0";
+                match_attr = "sample_config";   //该字段的值必须和device_info.hcs中的deviceMatchAttr值一致
+            }
+        }
+        ```
+
+        配置信息定义之后，需要将该配置文件添加到板级配置入口文件hdf.hcs（这一块可以通过OpenHarmony驱动子系统在DevEco集成驱动开发套件工具一键式配置，具体使用方法参考驱动开发套件中的介绍），示例如下：
+
+        ```
+        #include "device_info/device_info.hcs"
+        #include "sample/sample_config.hcs"
+        ```
+
+
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>驱动加载方式支持按需加载和按序加载两种方式，具体使用方法如下：
+>-   按需加载
+>    ```
+>    typedef enum {
+>        DEVICE_PRELOAD_ENABLE = 0,
+>        DEVICE_PRELOAD_ENABLE_STEP2,
+>        DEVICE_PRELOAD_DISABLE,
+>        DEVICE_PRELOAD_INVALID
+>    } DevicePreload;
+>    ```
+>    配置文件中preload 字段配成 0 （DEVICE\_PRELOAD\_ENABLE ），则系统启动过程中默认加载；配成1（DEVICE\_PRELOAD\_ENABLE\_STEP2），当系统支持快启的时候，则在系统系统完成之后再加载这一类驱动，否则和DEVICE\_PRELOAD\_ENABLE 含义相同；配成2（DEVICE\_PRELOAD\_DISABLE），则系统启动过程中默认不加载，支持后续动态加载，当用户态获取驱动服务（参考[消息机制](drive-hdf-news.md)）时，如果驱动服务不存在时，HDF框架会尝试动态加载该驱动。
+>-   按序加载（需要驱动为默认加载）
+>    配置文件中的priority（取值范围为整数0到200）是用来表示host和驱动的优先级，不同的host内的驱动，host的priority值越小，驱动加载优先级越高；同一个host内驱动的priority值越小，加载优先级越高。

+## 配置概述<a name="section59914284576"></a>
+
+HCS\(**H**DF  **C**onfiguration  **S**ource\)是HDF驱动框架的配置描述源码，内容以Key-Value为主要形式。它实现了配置代码与驱动代码解耦，便于开发者进行配置管理。
+
+HC-GEN**\(H**DF  **C**onfiguration  **G**enerator**\)**是HCS配置转换工具，可以将HDF配置文件转换为软件可读取的文件格式：
+
+-   在弱性能环境中，转换为配置树源码，驱动可直接调用C代码获取配置。
+-   在高性能环境中，转换为HCB\(**H**DF  **C**onfiguration  **B**inary\)二进制文件，驱动可使用HDF框架提供的配置解析接口获取配置。
+
+以下是使用HCB模式的典型应用场景：
+
+**图 1**  配置使用流程图<a name="fig814111371944"></a>  
+
+
+![](figure/zh-cn_image_0000001053405727.png)
+
+HCS经过HC-GEN编译生成HCB文件，HDF驱动框架中的HCS Parser模块会从HCB文件中重建配置树，HDF驱动模块使用HCS Parser提供的配置读取接口获取配置内容。

+
+## 基本结构<a name="section173481622115918"></a>
+
+HCS主要分为属性\(Attribute\)和节点\(Node\)两种结构。
+
+**属性**
+
+属性即最小的配置单元，是一个独立的配置项。语法如下：
+
+```
+  attribute_name = value;
+```
+
+-   attribute\_name 是**字母、数字、下划线**的组合且必须以字母或下划线开头，字母区分大小写。
+
+-   value的可用格式如下：
+
+    -   数字常量，支持二进制、八进制、十进制、十六进制数，具体参考数据类型节。
+
+    -   字符串，内容使用双引号\(""\)引用。
+
+    -   节点引用。
+
+
+-   attribute 必须以分号\(;\)结束且必须属于一个node。
+
+
+**节点**
+
+节点是一组属性的集合，语法如下：
+
+```
+  node_name {
+      module = "sample";
+      ...
+  }
+```
+
+-   node\_name  是**字母、数字、下划线**的组合且必须以字母或下划线开头，字母区分大小写。
+
+-   大括号后无需添加结束符“;”。
+
+-   root为保留关键字，用于声明配置表的根节点。每个配置表必须以root节点开始。
+
+-   root节点中必须包含module属性，其值应该为一个字符串，用于表征该配置所属模块。
+
+-   节点中可以增加match\_attr属性，其值为一个全局唯一的字符串。在解析配置时可以调用查找接口以该属性的值查找到包含该属性的节点。
+
+## 数据类型<a name="section96521601302"></a>
+
+在属性定义中使用自动数据类型，不显式指定类型，属性支持的数据类型如下：
+
+**整型**
+
+整型长度自动推断，根据实际数据长度给与最小空间占用的类型。
+
+-   二进制，0b前缀，示例：0b1010。
+
+-   八进制，0前缀，示例：0664。
+-   十进制 ，无前缀，且支持有符号与无符号，示例：1024，+1024均合法。负值在读取时注意使用有符号数读取接口。
+
+-   十六进制，0x前缀，示例：0xff00、0xFF。
+
+
+**字符串**
+
+字符串使用双引号\(""\)表示。
+
+**数组**
+
+数组元素支持整型、字符串，不支持混合类型。整型数组中uint32\_t uint64\_t混用会向上转型为uint64\_t 数组。整型数组与字符串数组示例如下：
+
+```
+attr_foo = [0x01, 0x02, 0x03, 0x04];
+attr_bar = ["hello", "world"];
+```
+
+**bool类型**
+
+bool类型中**true**表示真，**false**表示假。
+
+## 预处理<a name="section8164295515"></a>
+
+**include**
+
+用于导入其他HCS文件。语法示例如下：
+
+```
+#include "foo.hcs"
+#include "../bar.hcs"
+```
+
+-   文件名必须使用双引号\(""\)，不在同一目录使用相对路径引用。被include文件也必须是合法的HCS文件。
+-   多个include，如果存在相同的节点，后者覆盖前者，其余的节点依次展开。
+
+## 注释<a name="section0338205819610"></a>
+
+支持两种注释风格。
+
+-   单行注释。
+
+    ```
+    // comment
+    ```
+
+-   多行注释。
+
+    ```
+    /*
+    comment
+    */
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >多行注释不支持嵌套。
+
+
+## 引用修改<a name="section179799204716"></a>
+
+引用修改可以实现修改另外任意一个节点的内容，语法为：
+
+```
+ node :& source_node
+```
+
+上述语句表示node中的内容是对source\_node节点内容的修改。示例如下：
+
+```
+root {
+    module = "sample";
+    foo {
+        foo_ :& root.bar{
+            attr = "foo";
+        }
+        foo1 :& foo2 {
+            attr = 0x2;
+        }
+        foo2 {
+            attr = 0x1;
+        }
+    }
+
+    bar {
+        attr = "bar";
+    }
+}
+```
+
+最终生成配置树为：
+
+```
+root {
+    module = "sample";
+    foo {
+        foo2 {
+            attr = 0x2;
+        }
+    }
+    bar {
+        attr = "foo";
+    }
+}
+```
+
+在以上示例中，可以看到foo.foo\_节点通过引用将bar.attr属性的值修改为了"foo"，foo.foo1节点通过引用将foo.foo2.attr属性的值修改为了0x2。foo.foo\_以及foo.foo1节点表示对目标节点内容的修改，其自身并不会存在最终生成的配置树中。
+
+-   引用同级node，可以直接使用node名称，否则被引用的节点必须使用绝对路径，节点间使用“.”分隔，root表示根节点，格式为root开始的节点路径序列，例如root.foo.bar即为一个合法的绝对路径。
+-   如果出现修改冲突（即多处修改同一个属性），编译器将提示warning，因为这种情况下只会生效某一个修改而导致最终结果不确定。
+
+## 节点复制<a name="section382424014712"></a>
+
+节点复制可以实现在节点定义时从另一个节点先复制内容，用于定义内容相似的节点。语法为：
+
+```
+ node : source_node
+```
+
+上述语句表示在定义"node"节点时将另一个节点"source\_node"的属性复制过来。示例如下：
+
+```
+root {
+	module = "sample";
+    foo {
+        attr_0 = 0x0;
+    }
+    bar:foo {
+        attr_1 = 0x1;
+    }
+}
+```
+
+上述代码的最终生成配置树为：
+
+```
+root {
+    module = "sample";
+    foo {
+        attr_0 = 0x0;
+    }
+    bar {
+        attr_1 = 0x1;
+        attr_0 = 0x0;
+    }
+}
+```
+
+在上述示例中，编译后bar节点即包含attr\_0属性也包含attr\_1属性，在bar中对attr\_0的修改不会影响到foo。
+
+在foo和bar在同级node中可不指定foo的路径，否则需要使用绝对路径引用，参考[引用修改](#section179799204716)。

+要对include导入的base配置树中不需要的节点或属性进行删除，可以使用delete关键字。下面的举例中sample1.hcs通过include导入了sample2.hcs中的配置内容，并使用delete删除了sample2.hcs中的attribute2属性和foo\_2节点，示例如下：
+
+```
+// sample2.hcs
+root {
+    attr_1 = 0x1;
+    attr_2 = 0x2;
+    foo_2 {
+        t = 0x1;
+    }
+}
+
+// sample1.hcs
+#include "sample2.hcs"
+root {
+    attr_2 = delete;
+    foo_2 : delete {
+    }
+}
+```
+
+上述代码在生成过程中将会删除root.foo\_2节点与attr\_2，最终生成配置树为：
+
+```
+root {
+    attr_1 = 0x1;
+}
+```
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>在同一个HCS文件中不允许使用delete，建议直接删除不需要的属性。
+
+## 属性引用<a name="section192841514490"></a>
+
+为了在解析配置时快速定位到关联的节点，可以把节点作为属性的右值，通过读取属性查找到对应节点。语法为：
+
+```
+ attribute = &node；
+```
+
+上述语句表示attribute的值是一个节点node的引用，在解析时可以用这个attribute快速定位到node，便于关联和查询其他node。示例如下：
+
+```
+node1 {
+    attributes;
+}
+
+node2 {
+    attr_1 = &node1;
+}
+```
+
+## 模板<a name="section520134294"></a>
+
+模板的用途在于生成严格一致的node结构，以便对同类型node进行遍历和管理。
+
+使用template关键字定义模板node，子node通过双冒号“::”声明继承关系。子节点可以改写但不能新增和删除template中的属性，子节点中没有定义的属性将使用template中的定义作为默认值。示例如下：
+
+```
+root {
+    module = "sample";
+    template foo {
+        attr_1 = 0x1;
+        attr_2 = 0x2;
+    }
+
+    bar :: foo {
+    }
+
+    bar_1 :: foo {
+        attr_1 = 0x2;
+    }
+}
+```
+
+生成配置树如下：
+
+```
+root {
+    module = "sample";
+    bar {
+        attr_1 = 0x1;
+        attr_2 = 0x2;
+    }
+    bar_1 {
+        attr_1 = 0x2;
+        attr_2 = 0x2;
+    }
+}
+```
+
+在上述示例中，bar和bar\_1节点继承了foo节点，生成配置树节点结构与foo保持了完全一致，只是属性的值不同。
+
+## 配置生成<a name="section106152531919"></a>
+
+hc-gen是配置生成的工具，可以对HCS配置语法进行检查并把HCS源文件转化成HCB二进制文件。
+
+## hc-gen介绍<a name="section8260625101012"></a>
+
+hc-gen参数说明：

+## 使用场景<a name="section33014541954"></a>
+
+当用户态应用和内核态驱动需要交互时，可以使用HDF框架的消息机制来实现。
+
+## 接口说明<a name="section538852311616"></a>
+
+消息机制的功能主要有以下两种：
+
+1.  用户态应用发送消息到驱动。
+2.  用户态应用接收驱动主动上报事件。
+

+
+## 开发步骤<a name="section946912121153"></a>
+
+1.  将驱动配置信息中服务策略policy字段设置为2（SERVICE\_POLICY\_CAPACITY，参考[policy定义](drive-hdf-servicemanage.md)）。
+
+    ```
+    device_sample :: Device {
+        policy = 2;
+        ...
+    }
+    ```
+
+2.  配置驱动信息中的服务设备节点权限（permission字段）是框架给驱动创建设备节点的权限，默认是0666，驱动开发者根据驱动的实际使用场景配置驱动设备节点的权限。
+3.  在服务实现过程中，实现服务基类成员IDeviceIoService中的Dispatch方法。
+
+    ```
+    // Dispatch是用来处理用户态发下来的消息
+    int32_t SampleDriverDispatch(struct HdfDeviceObject *device, int cmdCode, struct HdfSBuf *data, struct HdfSBuf *reply)
+    {
+        HDF_LOGE("sample driver lite A dispatch");
+        return 0;
+    }
+    int32_t SampleDriverBind(struct HdfDeviceObject *device)
+    {
+        HDF_LOGE("test for lite os sample driver A Open!");
+        if (device == NULL) {
+            HDF_LOGE("test for lite os sample driver A Open failed!");
+            return -1;
+        }
+        static struct ISampleDriverService sampleDriverA = {
+            .ioService.Dispatch = SampleDriverDispatch,
+            .ServiceA = SampleDriverServiceA,
+            .ServiceB = SampleDriverServiceB,
+        };
+        device->service = (struct IDeviceIoService *)(&sampleDriverA);
+        return 0;
+    }
+    ```
+
+4.  驱动定义消息处理函数中的cmd类型。
+
+    ```
+    #define SAMPLE_WRITE_READ 1    // 读写操作码1
+    ```
+
+5.  用户态获取服务接口并发送消息到驱动。
+
+    ```
+    int SendMsg(const char *testMsg)
+    {
+        if (testMsg == NULL) {
+            HDF_LOGE("test msg is null");
+            return -1;
+        }
+        struct HdfIoService *serv = HdfIoServiceBind("sample_driver");
+        if (serv == NULL) {
+            HDF_LOGE("fail to get service");
+            return -1;
+        }
+        struct HdfSBuf *data = HdfSBufObtainDefaultSize();
+        if (data == NULL) {
+            HDF_LOGE("fail to obtain sbuf data");
+            return -1;
+        }
+        struct HdfSBuf *reply = HdfSBufObtainDefaultSize();
+        if (reply == NULL) {
+            HDF_LOGE("fail to obtain sbuf reply");
+            ret = HDF_DEV_ERR_NO_MEMORY;
+            goto out;
+        }
+        if (!HdfSbufWriteString(data, testMsg)) {
+            HDF_LOGE("fail to write sbuf");
+            ret = HDF_FAILURE;
+            goto out;
+        }
+        int ret = serv->dispatcher->Dispatch(&serv->object, SAMPLE_WRITE_READ, data, reply);
+        if (ret != HDF_SUCCESS) {
+            HDF_LOGE("fail to send service call");
+            goto out;
+        }
+    out:
+        HdfSBufRecycle(data);
+        HdfSBufRecycle(reply);
+        HdfIoServiceRecycle(serv);
+        return ret;
+    }
+    ```
+
+6.  用户态接收该驱动上报的消息。
+    1.  用户态编写驱动上报消息的处理函数。
+
+        ```
+        static int OnDevEventReceived(void *priv,  uint32_t id, struct HdfSBuf *data)
+        {
+            OsalTimespec time;
+            OsalGetTime(&time);
+            HDF_LOGE("%s received event at %llu.%llu", (char *)priv, time.sec, time.usec);
+        
+            const char *string = HdfSbufReadString(data);
+            if (string == NULL) {
+                HDF_LOGE("fail to read string in event data");
+                return -1;
+            }
+            HDF_LOGE("%s: dev event received: %d %s",  (char *)priv, id, string);
+            return 0;
+        }
+        ```
+
+    2.  用户态注册接收驱动上报消息的操作方法。
+
+        ```
+        int RegisterListen()
+        {
+            struct HdfIoService *serv = HdfIoServiceBind("sample_driver");
+            if (serv == NULL) {
+                HDF_LOGE("fail to get service");
+                return -1;
+            }
+            static struct HdfDevEventlistener listener = {
+                .callBack = OnDevEventReceived,
+                .priv ="Service0"
+            };
+            if (HdfDeviceRegisterEventListener(serv, &listener) != 0) {
+                HDF_LOGE("fail to register event listener");
+                return -1;
+            }
+            ......
+            HdfDeviceUnregisterEventListener(serv, &listener);
+            HdfIoServiceRecycle(serv);
+            return 0;
+        }
+        ```
+
+    3.  驱动上报事件。
+
+        ```
+        int32_t SampleDriverDispatch(struct HdfDeviceObject *device, int cmdCode, struct HdfSBuf *data, struct HdfSBuf *reply)
+        {
+            ... // process api call here
+            return HdfDeviceSendEvent(deviceObject, cmdCode, data);
+        }
+        ```

+
+WLAN是基于HDF（Hardware Driver Foundation）驱动框架开发的模块，该模块可实现跨操作系统迁移，自适应器件差异，模块化拼装编译等功能。各WLAN厂商驱动开发人员可根据WLAN模块提供的向下统一接口适配各自的驱动代码，实现如下能力：建立/关闭WLAN热点、扫描、关联WLAN热点等；对HDI层向上提供能力如下：设置MAC地址、设置发射功率、获取设备的MAC地址等。[WLAN模块框架图](#fig967034316227)如下：

+### WLAN驱动接口架构<a name="section178022416377"></a>
+
+WLAN模块有三部分对外开放的API接口，如[下图2](#fig15016395217)所示：
+
+1. 对HDI层提供的能力接口。
+
+2. 驱动直接调用WLAN模块能力接口。
+
+3. 提供给各厂商实现的能力接口。

+## 开发指导<a name="section15957746172412"></a>
+
+WLAN驱动基于HDF框架和PLATFORM框架开发，不区分OS和芯片平台，为不同厂商的WLAN模组提供统一的驱动模型，各WLAN模组厂商根据如下指导适配WLAN驱动框架。
+
+### 开发步骤<a name="section11776186132513"></a>
+
+1.  通过wifi\_config.hcs文件，配置硬件参数：module\(不同feature\)，芯片等。
+2.  解析配置文件， 生成全量配置的结构体对象。
+3.  Module初始化，创建Module。
+4.  挂接chip，初始化chip。
+5.  总线初始化。
+6.  上层wpa业务挂接。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>以上驱动框架适配步骤一部分已经提供（详细见开发实例），待开发人员实现的部分有：1、根据硬件，修改配置参数；2、适配挂接chip；3、测试自验证。
+
+## 开发实例<a name="section1395253612512"></a>
+
+本例程提供WLAN模块初始化过程的完整使用流程。示例如下（以hi3881WLAN芯片为例）：
+
+1、根据硬件，修改配置参数。
+
+```
+/* 根据硬件参数，通过wlan_platform.hcs配置相关参数，以下是WLAN平台配置的示例 */

+            blockSize = 512; /* 读/写数据的块大小 */
+        }
+    }
+}
+/* 每一块芯片添加配置文件wlan_chip_<芯片名>.hcs（如：wlan_chip_hi3881.hcs），配置相关参数。以下是hi3881的配置示例 */
+root {
+    wlan_config {

+            chipHi3881 :: chipInst {
+                match_attr = "hdf_wlan_chips_hi3881";  /* 配置匹配标识 */
+                chipName = "hi3881";                   /* WLAN芯片的名称 */

+
+LCD（Liquid Crystal Display）液晶显示驱动，对LCD进行上电，并通过接口初始化LCD内部寄存器，使LCD正常工作。Display驱动模型基于HDF（ Hardware Driver Foundation）[驱动框架](drive-hdf-overview.md)开发，实现跨OS、跨平台，为LCD硬件提供上下电功能、发送初始化序列功能，使LCD进入正常的工作模式，显示芯片平台侧的图像数据，基于HDF驱动框架的Display驱动模型如[图1](#fig69138814229)。
+
+**图 1**  基于HDF驱动框架的Display驱动模型<a name="fig69138814229"></a>

+
+-   **Display驱动模型介绍**
+
+    Display驱动模型主要由平台驱动层、芯片平台适配层、LCD器件驱动层三部分组成。驱动模型基于HDF驱动框架开发，通过Platform层和OSAL层提供的接口，屏蔽内核形态的差异，使得器件驱动可以便利的迁移到不同OS及芯片平台。模型向上对接Display公共hal层，支撑HDI接口的实现，通过Display-HDI（Hardware Display Interface）对图形服务提供各类驱动能力接口。
+
+    （1）Display平台驱动层：通过HDF提供的IOService数据通道，与公共Hal层对接，集中接收并处理各类上层调用指令；
+
+    （2）SOC平台驱动适配层：借助此SOC适配层，实现Display驱动和SOC侧驱动解耦，主要完成芯片平台相关的参数配置，并传递平台驱动层的调用到器件驱动层；
+
+    （3）LCD器件驱动层：在器件驱动层中，主要实现和器件自身强相关的驱动适配接口，例如发送初始化序列、上下电、背光设置等。
+
+    基于Display驱动模型开发LCD驱动，可以借助平台提供的各种能力及接口，较大程度的降低器件驱动的开发周期和难度，提升开发效率。
+
+
+### 接口说明<a name="section14711163785519"></a>
+
+LCD接口通常可分为MIPI DSI接口、TTL接口和LVDS接口，常用的是MIPI DSI接口和TTL接口，下面对常用的MIPI DSI接口和TTL接口作简要介绍。
+
+-   MIPI DSI接口
+
+    **图 2**  MIPI DSI接口<a name="fig6936451331"></a>  
+    ![](figure/MIPI-DSI接口.png "MIPI-DSI接口")
+
+    MIPI DSI接口是MIPI（移动行业处理器接口）联盟定义的显示接口，主要用于移动终端显示屏接口，接口数据传输遵循MIPI协议，MIPI DSI接口为数据接口，传输图像数据，通常情况下MIPI DSI接口的控制信息以MIPI包形式通过MIPI DSI接口发送到对端IC，不需要额外的外设接口。
+
+-   TTL接口
+
+    **图 3**  TTL接口<a name="fig141611855635"></a>  
+    ![](figure/TTL接口.png "TTL接口")
+
+    TTL（Transistor Transistor Logic）即晶体管-晶体管逻辑，TTL电平信号由TTL器件产生，TTL器件是数字集成电路的一大门类，它采用双极型工艺制造，具有高速度、低功耗和品种多等特点。
+
+    TTL接口是并行方式传输数据的接口，有数据信号、时钟信号和控制信号（行同步、帧同步、数据有效信号等），在控制信号控制下完成数据传输。通常TTL接口的LCD，内部寄存器读写需要额外的外设接口，比如SPI接口、I2C接口等。
+
+
+## 开发指导<a name="section12394223125615"></a>
+
+Display驱动模型基于HDF驱动框架、Platform接口及OSAL接口开发，可以做到不区分OS（LiteOS、Linux）和芯片平台（Hi35xx、Hi38xx、V3S等），为LCD器件提供统一的驱动模型。
+
+### 开发步骤<a name="section515923045814"></a>
+
+1.  添加LCD驱动相关的设备描述配置。
+2.  在SOC平台驱动适配层中适配对应的芯片平台驱动。
+3.  添加器件驱动，并在驱动入口函数Init中注册Panel驱动数据，驱动数据接口主要包括如下接口：
+    -   LCD上下电
+
+        根据LCD硬件连接，使用Platform接口层提供的GPIO操作接口操作对应LCD管脚，例如复位管脚、IOVCC管脚，上电时序参考LCD供应商提供的SPEC。
+
+    -   发送初始化序列
+
+        根据LCD硬件接口，使用Platform接口层提供的I2C、SPI、MIPI等接口，下载LCD初始化序列，初始化参数序列可以参考LCD供应商提供的SPEC。
+
+
+4.  根据需求实现HDF框架其他接口，比如Release接口。
+5.  根据需求使用HDF框架可创建其他设备节点，用于业务逻辑或者调试功能。
+
+## 开发实例<a name="section7441155155813"></a>
+
+添加设备描述配置：
+
+```
+/* Display驱动相关的设备描述配置 */
+display :: host {
+    hostName = "display_host";
+    /* Display平台驱动设备描述 */
+    device_hdf_disp :: device {
+        device0 :: deviceNode {
+            policy = 2;
+            priority = 200;
+            permission = 0660;
+            moduleName = "HDF_DISP";
+            serviceName = "hdf_disp";
+        }
+    }
+    /* SOC适配层驱动设备描述 */
+    device_hi35xx_disp :: device {
+        device0 :: deviceNode {
+            policy = 0;
+            priority = 199;
+            moduleName = "HI351XX_DISP";
+        }
+    }
+    /* LCD器件驱动设备描述 */
+    device_lcd :: device {
+        device0 :: deviceNode {
+            policy = 0;
+            priority = 100;
+            preload = 0;
+            moduleName = "LCD_Sample";
+        }
+        device1 :: deviceNode {
+            policy = 0;
+            priority = 100;
+            preload = 2;
+            moduleName = "LCD_SampleXX";
+        }
+    }
+}
+```
+
+SOC适配层驱动，以Hi35xx系列芯片为例，需要在本层驱动中适配MIPI等和芯片平台相关的配置，示例如下：
+
+```
+static int32_t MipiDsiInit(struct PanelInfo *info)
+{
+    int32_t ret;
+    struct DevHandle *mipiHandle = NULL;
+    struct MipiCfg cfg;
+
+    mipiHandle = MipiDsiOpen(0);
+    if (mipiHandle == NULL) {
+        HDF_LOGE("%s: MipiDsiOpen failure", __func__);
+        return HDF_FAILURE;
+    }
+    cfg.lane = info->mipi.lane;
+    cfg.mode = info->mipi.mode;
+    cfg.format = info->mipi.format;
+    cfg.burstMode = info->mipi.burstMode;
+    cfg.timing.xPixels = info->width;
+    cfg.timing.hsaPixels = info->hsw;
+    cfg.timing.hbpPixels = info->hbp;
+    cfg.timing.hlinePixels = info->width + info->hbp + info->hfp + info->hsw;
+    cfg.timing.vsaLines = info->vsw;
+    cfg.timing.vbpLines = info->vbp;
+    cfg.timing.vfpLines = info->vfp;
+    cfg.timing.ylines = info->height;
+    /* 0 : no care */
+    cfg.timing.edpiCmdSize = 0;
+    cfg.pixelClk = CalcPixelClk(info);
+    cfg.phyDataRate = CalcDataRate(info);
+    /* config mipi device */
+    ret = MipiDsiSetCfg(mipiHandle, &cfg);
+    if (ret != HDF_SUCCESS) {
+        HDF_LOGE("%s:MipiDsiSetCfg failure", __func__);
+    }
+    MipiDsiClose(mipiHandle);
+    HDF_LOGI("%s:pixelClk = %d, phyDataRate = %d\n", __func__,
+        cfg.pixelClk, cfg.phyDataRate);
+    return ret;
+}
+```
+

+**图 1**  Sensor驱动模型图<a name="fig10451455446"></a>  
+![](figure/Sensor驱动模型图.png "Sensor驱动模型图")
+
+Sensor驱动模型对外开放的API接口能力如下：
+
+-   提供Sensor HDI（**H**ardware  **D**river  **I**nterface）能力接口，简化服务开发。
+-   提供Sensor驱动模型能力接口：依赖HDF驱动框架实现Sensor器件驱动的注册，加载，去注册，器件探测等能力，提供同一类型Sensor器件驱动归一接口, 寄存器配置解析操作接口，总线访问抽象接口，平台抽象接口。
+-   提供开发者实现的能力接口：依赖HDF驱动框架的HCS\(**H**DF  **C**onfiguration  **S**ource\)配置管理，根据同类型Sensor差异化配置，实现Sensor器件参数序列化配置和器件部分操作接口，简化Sensor器件驱动开发。

+## 开发指导<a name="section1140943382"></a>
+
+Sensor驱动是基于HDF框架、PLATFORM和OSAL基础接口进行开发，不区分操作系统和芯片平台，为不同Sensor器件提供统一的驱动模型。本篇开发指导以加速度计传感器为例，介绍传感器驱动开发。
+
+### 开发步骤<a name="section7893102915819"></a>
+
+1.  加速度计传感器驱动注册。HDF驱动框架会提供统一的驱动管理模型，通过加速计传感器模块配置信息，识别并加载对应模块驱动。
+2.  加速度计传感器驱动初始化和去初始化。HDF驱动框架通过init入口函数，依次启动传感器设备驱动加载和分配传感器设备数据配置资源。HDF驱动框架通过release函数，释放驱动加载的资源和配置。
+3.  加速度计传感器寄存器组配置解析。不同类型传感器需要在hcs里配置器件对应的HCS配置文件，然后再设备驱动启动过程中探测器件是否在位，然后加载对应的配置文件，生成配置的结构体对象。
+4.  加速度计传感器驱动操作接口实现。实现各个类型传感器归一化驱动接口，如init，GetInfo，Enable，Disable，SetBatch，SetMode，SetOption，ReadSensorData等函数，完成传感器驱动配置下发和数据上报功能。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>传感器驱动模型已经提供一部分能力集，包括驱动设备管理能力，抽象总线和平台操作接口能力，通用配置操作接口能力，配置解析操作接口能力，接口参考[表2](#table1156812588320)。需要开发人员实现部分有：1、传感器部分操作接口（[表3](#table1083014911336)）；2、传感器HCS差异化数据配置；3、驱动基本功能验证。
+
+## 开发实例<a name="section257750691"></a>
+
+基于HDF驱动模型，加载启动加速度计传感器驱动，代码形式如下，具体原理可参考[HDF驱动开发指南](drive-hdf-development.md)。加速度传感器选择通讯接口方式为I2C，厂家选择博世BMI160加速度传感器。
+
+1.  加速度计传感器驱动入口注册
+
+-   加速度计传感器驱动入口函数实现
+
+```
+/* 注册加速度计传感器入口数据结构体对象 */
+struct HdfDriverEntry g_sensorAccelDevEntry = {
+    .moduleVersion = 1, /* 加速度计传感器模块版本号 */
+    .moduleName = "HDF_SENSOR_ACCEL", /* 加速度计传感器模块名，要与device_info.hcs文件里的加速度计moduleName字段值一样*/
+    .Bind = BindAccelDriver, /* 加速度计传感器绑定函数 */
+    .Init = InitAccelDriver, /* 加速度计传感器初始化函数 */
+    .Release = ReleaseAccelDriver, /* 加速度计传感器资源释放函数 */
+};
+
+/* 调用HDF_INIT将驱动入口注册到HDF框架中，在加载驱动时HDF框架会先调用Bind函数,再调用Init函数加载该驱动，当Init调用异常时，HDF框架会调用Release释放驱动资源并退出 */
+HDF_INIT(g_sensorAccelDevEntry);
+```
+
+-   加速度计传感器设备配置描述
+
+加速度传感器模型使用HCS作为配置描述源码，HCS配置字段详细介绍参考[配置管理](drive-hdf-manage.md)介绍。
+
+```
+/* 加速度计传感器设备HCS配置 */
+device_sensor_accel :: device {
+    device0 :: deviceNode {
+        policy = 1; /* policy字段是驱动服务发布的策略 */
+        priority = 105; /* 驱动启动优先级（0-200），值越大优先级越低，建议默认配100，优先级相同则不保证device的加载顺序 */
+        preload = 2; /* 驱动按需加载字段，0表示加载，2表示不加载 */
+        permission = 0664; /* 驱动创建设备节点权限 */
+        moduleName = "HDF_SENSOR_ACCEL"; /* 驱动名称，该字段的值必须和驱动入口结构的moduleName值一致 */
+        serviceName = "sensor_accel"; /* 驱动对外发布服务的名称，必须唯一 */
+        deviceMatchAttr = "hdf_sensor_accel_driver"; /* 驱动私有数据匹配的关键字，必须和驱动私有数据配置表中的match_attr值相等 */
+    }

+## 概述<a name="section175431838101617"></a>
+
+-   **Touchscreen驱动主要任务**
+
+    Touchscreen驱动用于驱动触摸屏使其正常工作，该驱动主要完成如下工作：对触摸屏驱动IC进行上电、配置硬件管脚并初始化其状态、注册中断、配置通信接口（I2C或SPI）、设定input相关配置、下载及更新固件等操作。
+
+
+-   **Touchscreen驱动层次说明**
+
+    本节主要介绍基于input驱动模型开发touchscreen器件驱动，其整体的框架模型如[图1](#fig6251184817261)。
+
+    Input驱动模型基于HDF驱动框架、PLATFORM接口、OSAL接口进行开发，向上对接规范化的驱动接口HDI（Hardware Driver Interface）层，通过Input-HDI层对外提供硬件能力，即上层input service可以通过HDI接口层获取相应的驱动能力，进而操控touchscreen等输入设备。
+
+
+**图 1**  基于HDF驱动框架的input驱动模型<a name="fig6251184817261"></a>  
+![](figure/基于HDF驱动框架的input驱动模型.png "基于HDF驱动框架的input驱动模型")
+
+-   **Input驱动模型介绍**
+
+    Input驱动模型核心部分由设备管理层、公共驱动层、器件驱动层组成。器件产生的数据借助平台数据通道能力从内核传递到用户态，驱动模型通过配置文件适配不同器件及硬件平台，提高开发者的器件驱动开发效率。如下部分为模型各部分的说明：
+
+    （1）input设备管理：为各类输入设备驱动提供input设备的注册、注销接口，同时统一管理input设备列表；
+
+    （2）input平台驱动：指各类input设备的公共抽象驱动（例如触摸屏的公共驱动），负责对板级硬件进行初始化、硬件中断处理、向manager注册input设备等；
+
+    （3）input器件驱动：指各器件厂家的差异化驱动，通过适配平台驱动预留的差异化接口，实现器件驱动开发量最小化；
+
+    （4）input数据通道：提供一套通用的数据上报通道，各类别的input设备驱动均可用此通道上报input事件；
+
+    （5）input配置解析：负责对input设备的板级配置及器件私有配置进行解析及管理。
+
+
+-   **基于HDF驱动框架开发器件驱动的优势**
+
+    在HDF（Hardware Driver Foundation）[驱动管理框架](drive-hdf-development.md)的基础上，input驱动模型调用OSAL接口层和Platfom接口层提供的基础接口进行开发，包括bus通信接口、操作系统原生接口（memory、lock、thread、timer等）。由于OSAL接口和Platform接口屏蔽了芯片平台差异，所以基于input驱动模型实现的touchscreen驱动可以进行跨平台、跨OS迁移，以便逐步实现驱动的一次开发，多端部署。
+
+
+### 接口说明<a name="section17667171301711"></a>
+
+Touchscreen器件的硬件接口相对简单，根据PIN脚的属性，可以简单分为如下三类:
+
+-   电源接口
+-   IO控制接口
+-   通信接口
+
+**图 2**  Touchscreen器件常用管脚<a name="fig1290384314416"></a>  
+![](figure/Touchscreen器件常用管脚.png "Touchscreen器件常用管脚")
+
+如上图所示的三类接口，分别做简要说明如下：
+
+1.  **电源接口**
+    -   LDO\_1P8：1.8v数字电路
+    -   LDO\_3P3：3.3v模拟电路
+
+        通常情况下，touchscreen驱动IC和LCD驱动IC是相互分离的，这种情况下，touchscreen驱动IC一般同时需要1.8v和3.3v两路供电。随着芯片演进，业内已有touchscreen驱动IC和LCD驱动IC集成在一颗IC中的芯片案例，对touchscreen而言，只需要关注1.8v供电即可，其内部需要的3.3v电源，会在驱动IC内部从LCD的VSP电源（典型值5.5V）中分出来。
+
+
+2.  **IO控制接口**
+    -   Reset：reset管脚，用于在系统休眠、唤醒时，由主机侧对驱动IC进行复位操作。
+    -   INT：中断管脚，需要在驱动初始化时，配置为输入上拉状态。在驱动IC检测到外部触摸信号后，通过操作中断管脚来触发中断，器件驱动则会在中断处理函数中进行报点数据读取等操作。
+
+3.  **通信接口**
+    -   I2C：由于touchscreen的报点数据量相对较少，所以一般选用I2C方式传输数据。I2C的具体协议及对应操作接口，可以参考Platform接口层中的[“I2C”使用指南](drive-platform-i2c-des.md#section1695201514281)。
+    -   SPI：部分厂商，由于需要传递的数据不止报点坐标，而是需要获取基础容值，数据量较大，所以会选用SPI通信方式。SPI的具体协议及对应操作接口，可以参考Platform接口层中的[“SPI” 使用指南](drive-platform-spi-des.md#section71363452477)。
+
+
+## 开发指导<a name="section65745222184"></a>
+
+Input驱动模型是基于HDF框架、Platform接口和OSAL接口开发，不区分操作系统和芯片平台，为touchscreen等输入器件提供统一的驱动开发架构。
+
+-   如下以touchscreen器件驱动为例，说明input驱动模型的完整加载流程：
+
+    （1）设备描述配置：由开发者参考已有模板进行设备描述配置，包括驱动加载顺序、板级硬件信息、器件私有数据信息等。
+
+    （2）加载input设备管理驱动：input设备管理驱动由HDF驱动加载，完成设备manager的创建并对其初始化。
+
+    （3）加载平台驱动：平台驱动由HDF框架加载，主要完成板级配置解析及硬件初始化，并提供器件注册接口。
+
+    （4）加载器件驱动：器件驱动也由HDF框架加载，完成器件设备的实例化，包括器件私有配置解析和平台预留的差异化接口适配。
+
+    （5）器件设备向平台驱动注册：将实例化的器件设备向平台驱动注册，实现设备和驱动的绑定，并完成中断注册、上下电等器件初始化工作。
+
+    （6）input设备注册：在器件初始化完成后，实例化input设备，并将其注册到input manager进行管理。
+
+
+### 开发步骤<a name="section865734181916"></a>
+
+1.  设备描述配置
+
+    目前Input驱动基于HDF驱动框架编写，驱动的加载启动由HDF驱动管理框架统一处理。首先需要在对应的配置文件中，将驱动信息注册进去，如是否加载、加载优先级，此后HDF驱动框架会逐一启动注册过的驱动模块。驱动的相关配置请参考[HDF驱动框架配置指导](drive-hdf-development.md#section1969312275533)。
+
+2.  板级配置及Touchscreen器件私有配置
+
+    配置对应的IO管脚功能，例如对单板上为touchscreen设计预留的I2C Pin脚，需设置对应的寄存器，使其选择I2C的通信功能。
+
+3.  实现器件差异化适配接口
+
+    根据硬件单板设计的通信接口，使用Platform接口层提供的管脚操作接口配置对应的复位管脚、中断管脚以及电源操作，对于GPIO的操作，可参考[GPIO操作接口指导](drive-platform-gpio-des.md#section259614242196)

+## 概述<a name="section1635911016188"></a>
+
+GPIO（General-purpose input/output）即通用型输入输出。通常，GPIO控制器通过分组的方式管理所有GPIO管脚，每组GPIO有一个或多个寄存器与之关联，通过读写寄存器完成对GPIO管脚的操作。
+
+GPIO接口定义了操作GPIO管脚的标准方法集合，包括：
+
+-   设置管脚方向： 方向可以是输入或者输出\(暂不支持高阻态\)
+
+-   读写管脚电平值： 电平值可以是低电平或高电平
+-   设置管脚中断服务函数：设置一个管脚的中断响应函数，以及中断触发方式
+-   使能和禁止管脚中断：禁止或使能管脚中断

+
+-   Hi3516DV300
+
+    控制器管理12组GPIO管脚，每组8个。
+
+    GPIO号 = GPIO组索引 \(0\~11\) \* 每组GPIO管脚数\(8\) + 组内偏移
+
+    举例：GPIO10\_3的GPIO号 = 10 \* 8 + 3 = 83
+

+
+    控制器管理10组GPIO管脚，每组10个。
+
+    GPIO号 = GPIO组索引 \(0\~9\) \* 每组GPIO管脚数\(10\) + 组内偏移

+
+本实例程序中，我们将测试一个GPIO管脚的中断触发：为管脚设置中断服务函数，触发方式为边沿触发，然后通过交替写高低电平到管脚，产生电平波动，制造触发条件，观察中断服务函数的执行。
+
+首先需要选取一个空闲的GPIO管脚，本例程基于Hi3516DV300某开发板，GPIO管脚选择GPIO10\_3，换算成GPIO号为83。
+
+读者可以根据自己使用的开发板，参考其原理图，选择一个空闲的GPIO管脚即可。

+## 概述<a name="section5361140416"></a>
+
+-   I2C\(Inter Integrated Circuit\)总线是由Philips公司开发的一种简单、双向二线制同步串行总线。
+-   I2C以主从方式工作，通常有一个主设备和一个或者多个从设备，主从设备通过SDA\(SerialData\)串行数据线以及SCL\(SerialClock\)串行时钟线两根线相连，如[图1 ](#fig1135561232714)所示。
+
+-   I2C数据的传输必须以一个起始信号作为开始条件，以一个结束信号作为传输的停止条件。数据传输以字节为单位，高位在前，逐个bit进行传输。
+-   I2C总线上的每一个设备都可以作为主设备或者从设备，而且每一个设备都会对应一个唯一的地址，当主设备需要和某一个从设备通信时，通过广播的方式，将从设备地址写到总线上，如果某个从设备符合此地址，将会发出应答信号，建立传输。
+
+-   I2C接口定义了完成I2C传输的通用方法集合，包括：
+
+    -   I2C控制器管理:  打开或关闭I2C控制器
+    -   I2C消息传输：通过消息传输结构体数组进行自定义传输

+
+本例程以操作开发板上的I2C设备为例，详细展示I2C接口的完整使用流程。
+
+本例拟对Hi3516DV300某开发板上TouchPad设备进行简单的寄存器读写访问，基本硬件信息如下：
+
+-   SOC：hi3516dv300。
+
+-   Touch IC：I2C地址为0x38, IC内部寄存器位宽为1字节。
+
+-   原理图信息：TouchPad设备挂接在3号I2C控制器下；IC的复位管脚为3号GPIO。
+
+本例程首先对Touch IC进行复位操作（开发板上电默认会给TouchIC供电，本例程不考虑供电），然后对其内部寄存器进行随机读写，测试I2C通路是否正常。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>本例程重点在于展示I2C设备访问流程，并验证I2C通路，所以对于设备寄存器读写值不做关注，读写寄存器导致的行为由设备自身决定。

+## 概述<a name="section16806142183217"></a>
+
+-   DSI（Display Serial Interface）是由移动行业处理器接口联盟（Mobile Industry Processor Interface \(MIPI\) Alliance）制定的规范，旨在降低移动设备中显示控制器的成本。它以串行的方式发送像素数据或指令给外设\(通常是LCD或者类似的显示设备\)，或从外设中读取状态信息或像素信息；它定义了主机、图像数据源和目标设备之间的串行总线和通信协议。
+
+-   MIPI-DSI具备高速模式和低速模式两种工作模式，全部数据通道都可以用于单向的高速传输，但只有第一个数据通道才可用于低速双向传输，从属端的状态信息、像素等是通过该数据通道返回。时钟通道专用于在高速传输数据的过程中传输同步时钟信号。
+-   图1显示了简化的DSI接口。从概念上看，符合DSI的接口与基于DBI-2和DPI-2标准的接口具有相同的功能。它向外围设备传输像素或命令数据，并且可以从外围设备读取状态或像素信息。主要区别在于，DSI对所有像素数据、命令和事件进行序列化，而在传统接口中，这些像素数据、命令和事件通常需要附加控制信号才能在并行数据总线上传输。

+
+RTC\(real-time clock\)为操作系统中的实时时钟设备，为操作系统提供精准的实时时间和定时报警功能。当设备下电后，通过外置电池供电，RTC继续记录操作系统时间；设备上电后，RTC提供实时时钟给操作系统，确保断电后系统时间的连续性。

+## 概述<a name="section1155271783811"></a>
+
+-   SDIO是安全数字输入输出接口（Secure Digital Input and Output）的缩写，是从SD内存卡接口的基础上演化出来的一种外设接口。SDIO接口兼容以前的SD内存卡，并且可以连接支持SDIO接口的设备。
+-   SDIO的应用比较广泛，目前，有许多手机都支持SDIO功能，并且很多SDIO外设也被开发出来，使得手机外接外设更加容易。常见的SDIO外设有WLAN、GPS、CAMERA、蓝牙等。
+-   SDIO总线有两端，其中一端是主机端（HOST），另一端是设备端（DEVICE）。所有的通信都是由HOST端发出命令开始的，在DEVICE端只要能解析HOST的命令，就可以同HOST进行通信了。SDIO的HOST可以连接多个DEVICE，如下图所示：
+
+    -   CLK信号：HOST给DEVICE的时钟信号。
+    -   VDD信号：电源信号。
+    -   VSS信号：Ground信号。
+    -   D0-3信号：4条数据线，其中，DAT1信号线复用为中断线，在1BIT模式下DAT0用来传输数据，在4BIT模式下DAT0-DAT3用来传输数据。
+    -   CMD信号：用于HOST发送命令和DEVICE回复响应。
+
+    **图 1**  SDIO的HOST-DEVICE连接示意图<a name="fig1185316527498"></a>  
+    
+
+    ![](figure/zh-cn_image_0000001054280608.png)
+
+-   SDIO接口定义了操作SDIO的通用方法集合，包括打开/关闭SDIO控制器、独占/释放HOST、使能/去使能设备、申请/释放中断、读写、获取/设置公共信息等。

+## 概述<a name="section193356154511"></a>
+
+-   SPI是串行外设接口（Serial Peripheral Interface）的缩写，是一种高速的，全双工，同步的通信总线。
+-   SPI是由Motorola公司开发，用于在主设备和从设备之间进行通信，常用于与闪存、实时时钟、传感器以及模数转换器等进行通信。
+-   SPI以主从方式工作，通常有一个主设备和一个或者多个从设备。主设备和从设备之间一般用4根线相连，它们分别是：
+    -   SCLK – 时钟信号，由主设备产生；
+    -   MOSI – 主设备数据输出，从设备数据输入；
+    -   MISO – 主设备数据输入，从设备数据输出；
+    -   CS – 片选，从设备使能信号，由主设备控制。
+
+
+-   一个主设备和两个从设备的连接示意图如[图1](#fig15227181812587)所示，Device A和Device B共享主设备的SCLK、MISO和MOSI三根引脚，Device A的片选CS0连接主设备的CS0，Device B的片选CS1连接主设备的CS1。
+
+**图 1**  SPI主从设备连接示意图。<a name="fig15227181812587"></a>  
+
+
+![](figure/zh-cn_image_0000001123742254.png)
+
+-   SPI通信通常由主设备发起，通过以下步骤完成一次通信：
+
+1.  通过CS选中要通信的从设备，在任意时刻，一个主设备上最多只能有一个从设备被选中。
+2.  通过SCLK给选中的从设备提供时钟信号。
+3.  基于SCLK时钟信号，主设备数据通过MOSI发送给从设备，同时通过MISO接收从设备发送的数据，完成通信。
+
+-   根据SCLK时钟信号的CPOL（Clock Polarity，时钟极性）和CPHA（Clock Phase，时钟相位）的不同组合，SPI有以下四种工作模式：
+    -   CPOL=0，CPHA=0 时钟信号idle状态为低电平，第一个时钟边沿采样数据。
+    -   CPOL=0，CPHA=1 时钟信号idle状态为低电平，第二个时钟边沿采样数据。
+    -   CPOL=1，CPHA=0 时钟信号idle状态为高电平，第一个时钟边沿采样数据。
+    -   CPOL=1，CPHA=1 时钟信号idle状态为高电平，第二个时钟边沿采样数据。
+
+
+-   SPI接口定义了操作SPI设备的通用方法集合，包括：
+    -   SPI设备句柄获取和释放。
+    -   SPI读写:  从SPI设备读取或写入指定长度数据。
+    -   SPI自定义传输：通过消息传输结构体执行任意读写组合过程。
+    -   SPI设备配置：获取和设置SPI设备属性。

+## 概述<a name="section833012453535"></a>
+
+-   UART是通用异步收发传输器（Universal Asynchronous Receiver/Transmitter）的缩写，是通用串行数据总线，用于异步通信。该总线双向通信，可以实现全双工传输。
+-   UART应用比较广泛，常用于输出打印信息，也可以外接各种模块，如GPS、蓝牙等。
+-   两个UART设备的连接示意图如下，UART与其他模块一般用2线（图1）或4线（图2）相连，它们分别是：
+    -   TX：发送数据端，和对端的RX相连；
+    -   RX：接收数据端，和对端的TX相连；
+    -   RTS：发送请求信号，用于指示本设备是否准备好，可接受数据，和对端CTS相连；
+    -   CTS：允许发送信号，用于判断是否可以向对端发送数据，和对端RTS相连；
+
+        **图 1**  2线UART设备连接示意图<a name="fig209936401896"></a>  
+        
+
+        ![](figure/zh-cn_image_0000001170262141.png)
+
+        **图 2**  4线UART设备连接示意图<a name="fig1435614171015"></a>  
+        
+
+        ![](figure/zh-cn_image_0000001123582482.png)
+
+
+-   UART通信之前，收发双方需要约定好一些参数：波特率、数据格式（起始位、数据位、校验位、停止位）等。通信过程中，UART通过TX发送给对端数据，通过RX接收对端发送的数据。当UART接收缓存达到预定的门限值时，RTS变为不可发送数据，对端的CTS检测到不可发送数据，则停止发送数据。
+-   UART接口定义了操作UART端口的通用方法集合，包括获取、释放设备句柄、读写数据、获取和设置波特率、获取和设置设备属性。

+
+看门狗（watchdog），又叫看门狗计时器（watchdog timer），是一种硬件的计时设备，当系统的主程序发生某些错误时，导致未及时清除看门狗计时器的计时值，这时看门狗计时器就会对系统发出复位信号，使系统从悬停状态恢复到正常运作状态。

+在本例程中，我们打开一个看门狗设备，设置超时时间并启动计时:
+
+-   首先定期喂狗，即按时清除看门狗定时器，确保系统不会因定时器超时而复位。
+-   接着再停止喂狗，观察定时器到期后系统是否发生复位行为。
+
+示例如下：
+
+```
+#include "watchdog_if.h"

+#include "osal_irq.h"

-# 传感器驱动开发实例<a name="ZH-CN_TOPIC_0000001097057435"></a>
-
-基于HDF驱动模型，加载启动加速度计传感器驱动，代码形式如下，具体原理可参考[HDF驱动开发指南](驱动开发.md)。加速度传感器选择通讯接口方式为I2C，厂家选择博世BMI160加速度传感器。
-
-1.  加速度计传感器驱动入口注册
-
--   加速度计传感器驱动入口函数实现
-
-```
-/* 注册加速度计传感器入口数据结构体对象 */
-struct HdfDriverEntry g_sensorAccelDevEntry = {
-    .moduleVersion = 1, /* 加速度计传感器模块版本号 */
-    .moduleName = "HDF_SENSOR_ACCEL", /* 加速度计传感器模块名，要与device_info.hcs文件里的加速度计moduleName字段值一样*/
-    .Bind = BindAccelDriver, /* 加速度计传感器绑定函数 */
-    .Init = InitAccelDriver, /* 加速度计传感器初始化函数 */
-    .Release = ReleaseAccelDriver, /* 加速度计传感器资源释放函数 */
-};
-
-/* 调用HDF_INIT将驱动入口注册到HDF框架中，在加载驱动时HDF框架会先调用Bind函数,再调用Init函数加载该驱动，当Init调用异常时，HDF框架会调用Release释放驱动资源并退出 */
-HDF_INIT(g_sensorAccelDevEntry);
-```
-
--   加速度计传感器设备配置描述
-
-加速度传感器模型使用HCS作为配置描述源码，HCS配置字段详细介绍参考[配置管理](配置管理.md)介绍。
-
-```
-/* 加速度计传感器设备HCS配置 */
-device_sensor_accel :: device {
-    device0 :: deviceNode {
-        policy = 1; /* policy字段是驱动服务发布的策略 */
-        priority = 105; /* 驱动启动优先级（0-200），值越大优先级越低，建议默认配100，优先级相同则不保证device的加载顺序 */
-        preload = 2; /* 驱动按需加载字段，0表示加载，2表示不加载 */
-        permission = 0664; /* 驱动创建设备节点权限 */
-        moduleName = "HDF_SENSOR_ACCEL"; /* 驱动名称，该字段的值必须和驱动入口结构的moduleName值一致 */
-        serviceName = "sensor_accel"; /* 驱动对外发布服务的名称，必须唯一 */
-        deviceMatchAttr = "hdf_sensor_accel_driver"; /* 驱动私有数据匹配的关键字，必须和驱动私有数据配置表中的match_attr值相等 */
-    }
-} 
-```
-
-1.  加速度计传感器驱动初始化和去初始化
-

--   [开发步骤](#section18816105182315)
-
-Sensor驱动是基于HDF框架、PLATFORM和OSAL基础接口进行开发，不区分操作系统和芯片平台，为不同Sensor器件提供统一的驱动模型。本篇开发指导以加速度计传感器为例，介绍传感器驱动开发。
-
-## 开发步骤<a name="section18816105182315"></a>
-
-1.  加速度计传感器驱动注册。HDF驱动框架会提供统一的驱动管理模型，通过加速计传感器模块配置信息，识别并加载对应模块驱动。
-2.  加速度计传感器驱动初始化和去初始化。HDF驱动框架通过init入口函数，依次启动传感器设备驱动加载和分配传感器设备数据配置资源。HDF驱动框架通过release函数，释放驱动加载的资源和配置。
-3.  加速度计传感器寄存器组配置解析。不同类型传感器需要在hcs里配置器件对应的HCS配置文件，然后再设备驱动启动过程中探测器件是否在位，然后加载对应的配置文件，生成配置的结构体对象。
-4.  加速度计传感器驱动操作接口实现。实现各个类型传感器归一化驱动接口，如init，GetInfo，Enable，Disable，SetBatch，SetMode，SetOption，ReadSensorData等函数，完成传感器驱动配置下发和数据上报功能。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->传感器驱动模型已经提供一部分能力集，包括驱动设备管理能力，抽象总线和平台操作接口能力，通用配置操作接口能力，配置解析操作接口能力，接口参考[表2](传感器驱动开发概述.md#table1156812588320)。需要开发人员实现部分有：1、传感器部分操作接口（[表3](传感器驱动开发概述.md#table1083014911336)）；2、传感器HCS差异化数据配置；3、驱动基本功能验证。

-Sensor驱动模型对外开放的API接口能力如下：
-
--   提供Sensor HDI（**H**ardware  **D**river  **I**nterface）能力接口，简化服务开发。
--   提供Sensor驱动模型能力接口：依赖HDF驱动框架实现Sensor器件驱动的注册，加载，去注册，器件探测等能力，提供同一类型Sensor器件驱动归一接口, 寄存器配置解析操作接口，总线访问抽象接口，平台抽象接口。
--   提供开发者实现的能力接口：依赖HDF驱动框架的HCS\(**H**DF  **C**onfiguration  **S**ource\)配置管理，根据同类型Sensor差异化配置，实现Sensor器件参数序列化配置和器件部分操作接口，简化Sensor器件驱动开发。

-# 看门狗使用实例<a name="ZH-CN_TOPIC_0000001052657651"></a>
-
-本例程提供看门狗的完整使用流程。
-
-在本例程中，我们打开一个看门狗设备，设置超时时间并启动计时:
-
--   首先定期喂狗，即按时清除看门狗定时器，确保系统不会因定时器超时而复位。
--   接着再停止喂狗，观察定时器到期后系统是否发生复位行为。
-
-示例如下：
-
-```
-#include "watchdog_if.h"
-#include "hdf_log.h"
-#include "osal_irq.h"
-#include "osal_time.h"
-
-#define WATCHDOG_TEST_TIMEOUT     2
-#define WATCHDOG_TEST_FEED_TIME   6
-
-static int32_t TestCaseWatchdog(void)
-{
-    int32_t i;
-    int32_t ret;
-    uint32_t timeout;
-    DevHandle handle = NULL;
-
-    /* 打开0号看门狗设备 */
-    handle = WatchdogOpen(0);
-    if (handle == NULL) {
-        HDF_LOGE("Open watchdog fail!");
-        return -1;
-    }
-
-    /* 设置超时时间 */
-    ret = WatchdogSetTimeout(handle, WATCHDOG_TEST_TIMEOUT);
-    if (ret != HDF_SUCCESS) {
-        HDF_LOGE("%s: set timeout fail! ret:%d\n", __func__, ret);
-        WatchdogClose(handle);
-        return ret;
-    }
-
-    /* 回读设置的超时时间值 */
-    ret = WatchdogGetTimeout(handle, &timeout);
-    if (ret != HDF_SUCCESS) {

-        WatchdogClose(handle);
-        return ret;
-    }
-    HDF_LOGI("%s: read timeout back:%u\n", __func__, timeout);
-

-
-    /* 每隔1S喂狗一次 */

-            return ret;
-        }
-        OsalSleep(1);
-    }
-    /* 由于喂狗间隔小于超时时间，系统不会发生复位，此日志可以正常打印 */
-    HDF_LOGE("%s: no reset ... feeding test OK!!!\n", __func__);
-
-    /* 接下来持续不喂狗，使得看门狗计时器超时 */
-    for (i = 0; i < WATCHDOG_TEST_FEED_TIME; i++) {
-        HDF_LOGE("%s: watiting dog buck %d times... \n", __func__, i);
-        OsalSleep(1);

-## 简介<a name="section3579126111816"></a>
-
-看门狗（watchdog），又叫看门狗计时器（watchdog timer），是一种硬件的计时设备，当系统的主程序发生某些错误时，导致未及时清除看门狗计时器的计时值，这时看门狗计时器就会对系统发出复位信号，使系统从悬停状态恢复到正常运作状态。

-## 配置概述<a name="section59914284576"></a>
-
-HCS\(**H**DF  **C**onfiguration  **S**ource\)是HDF驱动框架的配置描述源码，内容以Key-Value为主要形式。它实现了配置代码与驱动代码解耦，便于开发者进行配置管理。
-
-HC-GEN**\(H**DF  **C**onfiguration  **G**enerator**\)**是HCS配置转换工具，可以将HDF配置文件转换为软件可读取的文件格式：
-
--   在弱性能环境中，转换为配置树源码，驱动可直接调用C代码获取配置。
--   在高性能环境中，转换为HCB\(**H**DF  **C**onfiguration  **B**inary\)二进制文件，驱动可使用HDF框架提供的配置解析接口获取配置。
-
-以下是使用HCB模式的典型应用场景：

-**图 1**  配置使用流程图<a name="fig814111371944"></a>  
-
-
-![](figures/zh-cn_image_0000001053405727.png)
-
-HCS经过HC-GEN编译生成HCB文件，HDF驱动框架中的HCS Parser模块会从HCB文件中重建配置树，HDF驱动模块使用HCS Parser提供的配置读取接口获取配置内容。

-## 基本结构<a name="section173481622115918"></a>
-
-HCS主要分为属性\(Attribute\)和节点\(Node\)两种结构。
-
-**属性**
-
-属性即最小的配置单元，是一个独立的配置项。语法如下：
-
-```
-  attribute_name = value;
-```
-
--   attribute\_name 是**字母、数字、下划线**的组合且必须以字母或下划线开头，字母区分大小写。
-
--   value的可用格式如下：
-
-    -   数字常量，支持二进制、八进制、十进制、十六进制数，具体参考数据类型节。
-
-    -   字符串，内容使用双引号\(""\)引用。
-
-    -   节点引用。
-
-
--   attribute 必须以分号\(;\)结束且必须属于一个node。
-
-
-**节点**
-
-节点是一组属性的集合，语法如下：
-
-```
-  node_name {
-      module = "sample";
-      ...
-  }
-```
-
--   node\_name  是**字母、数字、下划线**的组合且必须以字母或下划线开头，字母区分大小写。
-
--   大括号后无需添加结束符“;”。
-
--   root为保留关键字，用于声明配置表的根节点。每个配置表必须以root节点开始。
-
--   root节点中必须包含module属性，其值应该为一个字符串，用于表征该配置所属模块。
-
--   节点中可以增加match\_attr属性，其值为一个全局唯一的字符串。在解析配置时可以调用查找接口以该属性的值查找到包含该属性的节点。
-
-## 数据类型<a name="section96521601302"></a>
-
-在属性定义中使用自动数据类型，不显式指定类型，属性支持的数据类型如下：
-
-**整型**
-
-整型长度自动推断，根据实际数据长度给与最小空间占用的类型。
-
--   二进制，0b前缀，示例：0b1010。
-
--   八进制，0前缀，示例：0664。
--   十进制 ，无前缀，且支持有符号与无符号，示例：1024，+1024均合法。负值在读取时注意使用有符号数读取接口。
-
--   十六进制，0x前缀，示例：0xff00、0xFF。
-
-
-**字符串**
-
-字符串使用双引号\(""\)表示。
-
-**数组**
-
-数组元素支持整型、字符串，不支持混合类型。整型数组中uint32\_t uint64\_t混用会向上转型为uint64\_t 数组。整型数组与字符串数组示例如下：
-
-```
-attr_foo = [0x01, 0x02, 0x03, 0x04];
-attr_bar = ["hello", "world"];
-```
-
-**bool类型**
-
-bool类型中**true**表示真，**false**表示假。
-
-## 预处理<a name="section8164295515"></a>
-
-**include**
-
-用于导入其他HCS文件。语法示例如下：
-
-```
-#include "foo.hcs"
-#include "../bar.hcs"
-```
-
--   文件名必须使用双引号\(""\)，不在同一目录使用相对路径引用。被include文件也必须是合法的HCS文件。
--   多个include，如果存在相同的节点，后者覆盖前者，其余的节点依次展开。
-
-## 注释<a name="section0338205819610"></a>
-
-支持两种注释风格。
-
--   单行注释。
-
-    ```
-    // comment
-    ```
-
--   多行注释。
-
-    ```
-    /*
-    comment
-    */
-    ```
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >多行注释不支持嵌套。

-引用修改可以实现修改另外任意一个节点的内容，语法为：
-
-```
- node :& source_node
-```
-
-上述语句表示node中的内容是对source\_node节点内容的修改。示例如下：
-
-```
-root {
-    module = "sample";
-    foo {
-        foo_ :& root.bar{
-            attr = "foo";
-        }
-        foo1 :& foo2 {
-            attr = 0x2;
-        }
-        foo2 {
-            attr = 0x1;
-        }
-    }
-
-    bar {
-        attr = "bar";
-    }
-}
-```
-
-最终生成配置树为：
-
-```
-root {
-    module = "sample";
-    foo {
-        foo2 {
-            attr = 0x2;
-        }
-    }
-    bar {
-        attr = "foo";
-    }
-}
-```
-
-在以上示例中，可以看到foo.foo\_节点通过引用将bar.attr属性的值修改为了"foo"，foo.foo1节点通过引用将foo.foo2.attr属性的值修改为了0x2。foo.foo\_以及foo.foo1节点表示对目标节点内容的修改，其自身并不会存在最终生成的配置树中。
-
--   引用同级node，可以直接使用node名称，否则被引用的节点必须使用绝对路径，节点间使用“.”分隔，root表示根节点，格式为root开始的节点路径序列，例如root.foo.bar即为一个合法的绝对路径。
--   如果出现修改冲突（即多处修改同一个属性），编译器将提示warning，因为这种情况下只会生效某一个修改而导致最终结果不确定。
-
-## 节点复制<a name="section382424014712"></a>
-
-节点复制可以实现在节点定义时从另一个节点先复制内容，用于定义内容相似的节点。语法为：
-
-```
- node : source_node
-```
-
-上述语句表示在定义"node"节点时将另一个节点"source\_node"的属性复制过来。示例如下：
-
-```
-root {
-	module = "sample";
-    foo {
-        attr_0 = 0x0;
-    }
-    bar:foo {
-        attr_1 = 0x1;
-    }
-}
-```
-
-上述代码的最终生成配置树为：
-
-```
-root {
-    module = "sample";
-    foo {
-        attr_0 = 0x0;
-    }
-    bar {
-        attr_1 = 0x1;
-        attr_0 = 0x0;
-    }
-}
-```
-
-在上述示例中，编译后bar节点即包含attr\_0属性也包含attr\_1属性，在bar中对attr\_0的修改不会影响到foo。
-
-在foo和bar在同级node中可不指定foo的路径，否则需要使用绝对路径引用，参考[引用修改](#section179799204716)。
-
-## 删除<a name="section165211112586"></a>
-
-要对include导入的base配置树中不需要的节点或属性进行删除，可以使用delete关键字。下面的举例中sample1.hcs通过include导入了sample2.hcs中的配置内容，并使用delete删除了sample2.hcs中的attribute2属性和foo\_2节点，示例如下：
-
-```
-// sample2.hcs
-root {
-    attr_1 = 0x1;
-    attr_2 = 0x2;
-    foo_2 {
-        t = 0x1;
-    }
-}
-
-// sample1.hcs
-#include "sample2.hcs"
-root {
-    attr_2 = delete;
-    foo_2 : delete {
-    }
-}
-```
-
-上述代码在生成过程中将会删除root.foo\_2节点与attr\_2，最终生成配置树为：
-
-```
-root {
-    attr_1 = 0x1;
-}
-```
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->在同一个HCS文件中不允许使用delete，建议直接删除不需要的属性。
-
-## 属性引用<a name="section192841514490"></a>
-
-为了在解析配置时快速定位到关联的节点，可以把节点作为属性的右值，通过读取属性查找到对应节点。语法为：
-
-```
- attribute = &node；
-```
-
-上述语句表示attribute的值是一个节点node的引用，在解析时可以用这个attribute快速定位到node，便于关联和查询其他node。示例如下：
-
-```
-node1 {
-    attributes;
-}
-
-node2 {
-    attr_1 = &node1;
-}
-```
-
-## 模板<a name="section520134294"></a>
-
-模板的用途在于生成严格一致的node结构，以便对同类型node进行遍历和管理。
-
-使用template关键字定义模板node，子node通过双冒号“::”声明继承关系。子节点可以改写但不能新增和删除template中的属性，子节点中没有定义的属性将使用template中的定义作为默认值。示例如下：
-
-```
-root {
-    module = "sample";
-    template foo {
-        attr_1 = 0x1;
-        attr_2 = 0x2;
-    }
-
-    bar :: foo {
-    }
-
-    bar_1 :: foo {
-        attr_1 = 0x2;
-    }
-}
-```
-
-生成配置树如下：
-
-```
-root {
-    module = "sample";
-    bar {
-        attr_1 = 0x1;
-        attr_2 = 0x2;
-    }
-    bar_1 {
-        attr_1 = 0x2;
-        attr_2 = 0x2;
-    }
-}
-```
-
-在上述示例中，bar和bar\_1节点继承了foo节点，生成配置树节点结构与foo保持了完全一致，只是属性的值不同。
-
-## 配置生成<a name="section106152531919"></a>
-
-hc-gen是配置生成的工具，可以对HCS配置语法进行检查并把HCS源文件转化成HCB二进制文件。
-
-## hc-gen介绍<a name="section8260625101012"></a>
-
-hc-gen参数说明：

-## 驱动模型介绍<a name="section157425168112"></a>
-
-HDF框架以组件化的驱动模型作为核心设计思路，为开发者提供更精细化的驱动管理，让驱动开发和部署更加规范。HDF框架将一类设备驱动放在同一个host里面，开发者也可以将驱动功能分层独立开发和部署，支持一个驱动多个node，HDF框架管理驱动模型如下图所示：
-
-**图 1**  HDF框架管理驱动模型<a name="fig5487113011526"></a>  
-
-
-![](figures/zh-cn_image_0000001054564784.png)
-
-## 驱动开发步骤<a name="section1969312275533"></a>
-
-基于HDF框架进行驱动的开发主要分为两个部分，驱动实现和驱动配置，详细开发流程如下所示：
-
-1.  <a name="li35182436435"></a>驱动实现
-
-    驱动实现包含驱动业务代码和驱动入口注册，具体写法如下：
-
-    -   驱动业务代码
-
-        ```
-        #include "hdf_device_desc.h"  // HDF框架对驱动开放相关能力接口的头文件
-        #include "hdf_log.h"          // HDF 框架提供的日志接口头文件
-        
-        #define HDF_LOG_TAG "sample_driver"   // 打印日志所包含的标签，如果不定义则用默认定义的HDF_TAG标签
-        
-        //驱动对外提供的服务能力，将相关的服务接口绑定到HDF框架
-        int32_t HdfSampleDriverBind(struct HdfDeviceObject *deviceObject)
-        {
-            HDF_LOGD("Sample driver bind success");
-            return 0;
-        }
-        
-        // 驱动自身业务初始的接口
-        int32_t HdfSampleDriverInit(struct HdfDeviceObject *deviceObject)
-        {
-            HDF_LOGD("Sample driver Init success");
-            return 0;
-        }
-        
-        // 驱动资源释放的接口
-        void HdfSampleDriverRelease(struct HdfDeviceObject *deviceObject)
-        {
-            HDF_LOGD("Sample driver release success");
-            return;
-        }
-        ```
-
-    -   驱动入口注册到HDF框架
-
-        ```
-        // 定义驱动入口的对象，必须为HdfDriverEntry（在hdf_device_desc.h中定义）类型的全局变量
-        struct HdfDriverEntry g_sampleDriverEntry = {
-            .moduleVersion = 1,
-            .moduleName = "sample_driver",
-            .Bind = HdfSampleDriverBind,
-            .Init = HdfSampleDriverInit,
-            .Release = HdfSampleDriverRelease,
-        };
-        
-        // 调用HDF_INIT将驱动入口注册到HDF框架中，在加载驱动时HDF框架会先调用Bind函数,再调用Init函数加载该驱动，当Init调用异常时，HDF框架会调用Release释放驱动资源并退出。
-        HDF_INIT(g_sampleDriverEntry);
-        ```
-
-
-2.  驱动编译
-    -   驱动代码的编译必须要使用HDF框架提供的Makefile模板进行编译。
-
-        ```
-        include $(LITEOSTOPDIR)/../../drivers/adapter/lite/khdf/lite.mk #导入hdf预定义内容，必需
-        MODULE_NAME :=    #生成的结果文件
-        LOCAL_INCLUDE :=  #本驱动的头文件目录
-        LOCAL_SRCS :=     #本驱动的源代码文件
-        LOCAL_CFLAGS ：=  #自定义的编译选项
-        include $(HDF_DRIVER) #导入模板makefile完成编译
-        ```
-
-    -   编译结果文件链接到内核镜像，添加到vendor目录下的hdf\_vendor.mk里面，示例如下：
-
-        ```
-        LITEOS_BASELIB +=  -lxxx  #链接生成的静态库
-        LIB_SUBDIRS    +=         #驱动代码Makefile的目录
-        ```
-
-
-3.  驱动配置
-
-    HDF使用HCS作为配置描述源码，HCS详细介绍参考[配置管理](配置管理.md)介绍。
-
-    驱动配置包含两部分，HDF框架定义的驱动设备描述和驱动的私有配置信息，具体写法如下：
-
-    -   驱动设备描述（必选）
-
-        HDF框架加载驱动所需要的信息来源于HDF框架定义的驱动设备描述，因此基于HDF框架开发的驱动必须要在HDF框架定义的device\_info.hcs配置文件中添加对应的设备描述，驱动的设备描述填写如下所示：
-
-        ```
-        root {
-            device_info {
-                match_attr = "hdf_manager";
-                template host {       // host模板，继承该模板的节点（如下sample_host）如果使用模板中的默认值，则节点字段可以缺省
-                    hostName = "";
-                    priority = 100;
-                    template device {
-                        template deviceNode {
-                            policy = 0;
-                            priority = 100;
-                            preload = 0;
-                            permission = 0664;
-                            moduleName = "";
-                            serviceName = "";
-                            deviceMatchAttr = "";
-                        }
-                    }
-                }
-                sample_host :: host{
-                    hostName = "host0";    // host名称，host节点是用来存放某一类驱动的容器
-                    priority = 100;        // host启动优先级（0-200），值越大优先级越低，建议默认配100，优先级相同则不保证host的加载顺序
-                    device_sample :: device {        // sample设备节点
-                        device0 :: deviceNode {      // sample驱动的DeviceNode节点
-                            policy = 1;              // policy字段是驱动服务发布的策略，在驱动服务管理章节有详细介绍
-                            priority = 100;          // 驱动启动优先级（0-200），值越大优先级越低，建议默认配100，优先级相同则不保证device的加载顺序
-                            preload = 0;             // 驱动按需加载字段，在本章节最后的说明有详细介绍
-                            permission = 0664;       // 驱动创建设备节点权限
-                            moduleName = "sample_driver";   // 驱动名称，该字段的值必须和驱动入口结构的moduleName值一致
-                            serviceName = "sample_service";    // 驱动对外发布服务的名称，必须唯一
-                            deviceMatchAttr = "sample_config"; // 驱动私有数据匹配的关键字，必须和驱动私有数据配置表中的match_attr值相等
-                        }
-                    }
-                }
-            }
-        }
-        ```
-
-    -   驱动私有配置信息（可选）
-
-        如果驱动有私有配置，则可以添加一个驱动的配置文件，用来填写一些驱动的默认配置信息，HDF框架在加载驱动的时候，会将对应的配置信息获取并保存在HdfDeviceObject 中的property里面，通过Bind和Init（参考[驱动开发](#li35182436435)）传递给驱动，驱动的配置信息示例如下：
-
-        ```
-        root {
-            SampleDriverConfig {
-                sample_version = 1;
-                sample_bus = "I2C_0";
-                match_attr = "sample_config";   //该字段的值必须和device_info.hcs中的deviceMatchAttr值一致
-            }
-        }
-        ```
-
-        配置信息定义之后，需要将该配置文件添加到板级配置入口文件hdf.hcs（这一块可以通过OpenHarmony驱动子系统在DevEco集成驱动开发套件工具一键式配置，具体使用方法参考驱动开发套件中的介绍），示例如下：
-
-        ```
-        #include "device_info/device_info.hcs"
-        #include "sample/sample_config.hcs"
-        ```
-
-
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->驱动加载方式支持按需加载和按序加载两种方式，具体使用方法如下：
->-   按需加载
->    ```
->    typedef enum {
->        DEVICE_PRELOAD_ENABLE = 0,
->        DEVICE_PRELOAD_ENABLE_STEP2,
->        DEVICE_PRELOAD_DISABLE,
->        DEVICE_PRELOAD_INVALID
->    } DevicePreload;
->    ```
->    配置文件中preload 字段配成 0 （DEVICE\_PRELOAD\_ENABLE ），则系统启动过程中默认加载；配成1（DEVICE\_PRELOAD\_ENABLE\_STEP2），当系统支持快启的时候，则在系统系统完成之后再加载这一类驱动，否则和DEVICE\_PRELOAD\_ENABLE 含义相同；配成2（DEVICE\_PRELOAD\_DISABLE），则系统启动过程中默认不加载，支持后续动态加载，当用户态获取驱动服务（参考[消息机制](驱动消息机制管理.md)）时，如果驱动服务不存在时，HDF框架会尝试动态加载该驱动。
->-   按序加载（需要驱动为默认加载）
->    配置文件中的priority（取值范围为整数0到200）是用来表示host和驱动的优先级，不同的host内的驱动，host的priority值越小，驱动加载优先级越高；同一个host内驱动的priority值越小，加载优先级越高。

-## 开发步骤<a name="section946912121153"></a>
-
-1.  将驱动配置信息中服务策略policy字段设置为2（SERVICE\_POLICY\_CAPACITY，参考[policy定义](驱动服务管理.md)）。
-
-    ```
-    device_sample :: Device {
-        policy = 2;
-        ...
-    }
-    ```
-
-2.  配置驱动信息中的服务设备节点权限（permission字段）是框架给驱动创建设备节点的权限，默认是0666，驱动开发者根据驱动的实际使用场景配置驱动设备节点的权限。
-3.  在服务实现过程中，实现服务基类成员IDeviceIoService中的Dispatch方法。
-
-    ```
-    // Dispatch是用来处理用户态发下来的消息
-    int32_t SampleDriverDispatch(struct HdfDeviceObject *device, int cmdCode, struct HdfSBuf *data, struct HdfSBuf *reply)
-    {
-        HDF_LOGE("sample driver lite A dispatch");
-        return 0;
-    }
-    int32_t SampleDriverBind(struct HdfDeviceObject *device)
-    {
-        HDF_LOGE("test for lite os sample driver A Open!");
-        if (device == NULL) {
-            HDF_LOGE("test for lite os sample driver A Open failed!");
-            return -1;
-        }
-        static struct ISampleDriverService sampleDriverA = {
-            .ioService.Dispatch = SampleDriverDispatch,
-            .ServiceA = SampleDriverServiceA,
-            .ServiceB = SampleDriverServiceB,
-        };
-        device->service = (struct IDeviceIoService *)(&sampleDriverA);
-        return 0;
-    }
-    ```
-
-4.  驱动定义消息处理函数中的cmd类型。
-
-    ```
-    #define SAMPLE_WRITE_READ 1    // 读写操作码1
-    ```
-
-5.  用户态获取服务接口并发送消息到驱动。
-
-    ```
-    int SendMsg(const char *testMsg)
-    {
-        if (testMsg == NULL) {
-            HDF_LOGE("test msg is null");
-            return -1;
-        }
-        struct HdfIoService *serv = HdfIoServiceBind("sample_driver");
-        if (serv == NULL) {
-            HDF_LOGE("fail to get service");
-            return -1;
-        }
-        struct HdfSBuf *data = HdfSBufObtainDefaultSize();
-        if (data == NULL) {
-            HDF_LOGE("fail to obtain sbuf data");
-            return -1;
-        }
-        struct HdfSBuf *reply = HdfSBufObtainDefaultSize();
-        if (reply == NULL) {
-            HDF_LOGE("fail to obtain sbuf reply");
-            ret = HDF_DEV_ERR_NO_MEMORY;
-            goto out;
-        }
-        if (!HdfSbufWriteString(data, testMsg)) {
-            HDF_LOGE("fail to write sbuf");
-            ret = HDF_FAILURE;
-            goto out;
-        }
-        int ret = serv->dispatcher->Dispatch(&serv->object, SAMPLE_WRITE_READ, data, reply);
-        if (ret != HDF_SUCCESS) {
-            HDF_LOGE("fail to send service call");
-            goto out;
-        }
-    out:
-        HdfSBufRecycle(data);
-        HdfSBufRecycle(reply);
-        HdfIoServiceRecycle(serv);
-        return ret;
-    }
-    ```
-
-6.  用户态接收该驱动上报的消息。
-    1.  用户态编写驱动上报消息的处理函数。
-
-        ```
-        static int OnDevEventReceived(void *priv,  uint32_t id, struct HdfSBuf *data)
-        {
-            OsalTimespec time;
-            OsalGetTime(&time);
-            HDF_LOGE("%s received event at %llu.%llu", (char *)priv, time.sec, time.usec);
-        
-            const char *string = HdfSbufReadString(data);
-            if (string == NULL) {
-                HDF_LOGE("fail to read string in event data");
-                return -1;
-            }
-            HDF_LOGE("%s: dev event received: %d %s",  (char *)priv, id, string);
-            return 0;
-        }
-        ```
-
-    2.  用户态注册接收驱动上报消息的操作方法。
-
-        ```
-        int RegisterListen()
-        {
-            struct HdfIoService *serv = HdfIoServiceBind("sample_driver");
-            if (serv == NULL) {
-                HDF_LOGE("fail to get service");
-                return -1;
-            }
-            static struct HdfDevEventlistener listener = {
-                .callBack = OnDevEventReceived,
-                .priv ="Service0"
-            };
-            if (HdfDeviceRegisterEventListener(serv, &listener) != 0) {
-                HDF_LOGE("fail to register event listener");
-                return -1;
-            }
-            ......
-            HdfDeviceUnregisterEventListener(serv, &listener);
-            HdfIoServiceRecycle(serv);
-            return 0;
-        }
-        ```
-
-    3.  驱动上报事件。
-
-        ```
-        int32_t SampleDriverDispatch(struct HdfDeviceObject *device, int cmdCode, struct HdfSBuf *data, struct HdfSBuf *reply)
-        {
-            ... // process api call here
-            return HdfDeviceSendEvent(deviceObject, cmdCode, data);
-        }
-        ```

-### 搭建Docker环境-标准系统类设备（参考内存≥128MB）<a name="section13585262391"></a>
-
-**方式一：从HuaweiCloud SWR上直接获取Docker镜像进行构建：**
-
-1.  获取Docker镜像。
-
-    ```
-    docker pull swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.1
-    ```
-
-2.  进入OpenHarmony代码根目录执行如下命令，从而进入Docker构建环境。
-
-    ```
-    docker run -it -v $(pwd):/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.1
-    ```
-
-
-**方式二：通过Dockerfile 构建本地Docker镜像进行构建**
-
-1.  获取Dockerfile脚本文件，用来构建本地Docker镜像。
-
-    ```
-    git clone https://gitee.com/openharmony/docs.git
-    ```
-
-2.  进入Dockerfile代码目录路径执行Docker镜像构建命令。
-
-    ```
-    cd docs/docker/standard
-    ./build.sh
-    ```
-
-3.  进入OpenHarmony代码根目录执行如下命令，从而进入Docker构建环境。
-
-    ```
-    docker run -it -v $(pwd):/home/openharmony openharmony-docker-standard:0.0.1
-    ```
-
-
-### 编译源码-标准系统类设备（参考内存≥128MB）<a name="section193711513406"></a>
-
-1.  在源码的根目录执行预处理脚本。
-
-    ```
-    ../scripts/prepare.sh
-    ```
-
-2.  通过如下编译脚本启动标准系统类设备（参考内存≥128MB）的编译。
-
-    ```
-    ./build.sh --product-name {product_name}
-    ```
-
-    \{product\_name\}为当前版本支持的平台。比如：Hi3516DV300等。
-
-    编译所生成的文件都归档在out/ohos-arm-release/目录下，结果镜像输出在 out/ohos-arm-release/packages/phone/images/ 目录下。

-
-## 基于HPM的Docker环境<a name="section485713518337"></a>
-
-docker\_dist是一个[HPM](https://hpm.harmonyos.com/)系统中的模板组件，能够帮助用户快速初始化HPM工程，利用docker镜像来快速编译OpenHarmony发行版，在很大程度上简化了编译前的环境配置。开发者在配置好Ubuntu和[hpm-cli](https://device.harmonyos.com/cn/docs/develop/bundles/oem_bundle_guide_prepare-0000001050129846)开发环境后，可以通过以下步骤来使用我们提供的Docker环境。
-
-### 搭建Docker环境<a name="section3295842510"></a>
-
-1.  初始化安装模板。在任意工作目录中执行以下命令。
-
-    ```
-    hpm init -t @ohos/docker_dist
-    ```
-
-2.  修改publishAs。
-
-    因为获取到的是模板类型的包，要把包的类型改为需要的类型。 在当前目录下打开bundle.json文件，把"publishAs"字段的值由"template"改为"distribution"。
-
-
-### 获取及编译源码<a name="section69141039143518"></a>
-
-执行编译。自动安装docker只能在Ubuntu环境下执行，如果其他环境，需要用户自行安装docker，然后拉取镜像，执行编译。
-
--   **自动安装docker（Ubuntu环境）**
-
-    以下命令可以帮助用户自动安装docker, 拉取镜像，并且在容器中开始运行对应解决方案的拉取和编译。
-
-    **方式一：**
-
-    命令后接参数指定解决方案，格式如下：
-
-    ```
-    hpm run docker solution={product}
-    ```
-
-    \{product\}为需编译的解决方案，如：@ohos/hispark\_taurus、@ohos/hispark\_aries、@ohos/hispark\_pegasus。
-
-    **方式二：**
-
-    设置环境变量来选择解决方案，再执行编译命令。
-
-    1.  选择解决方案。
-
-        ```
-        export solution={product}
-        ```
-
-        \{product\}为需编译的解决方案，如：@ohos/hispark\_taurus、@ohos/hispark\_aries、@ohos/hispark\_pegasus。
-
-    2.  获取源码及执行编译。
-
-        ```
-        hpm run docker
-        ```
-
-
-    以上两种方式以@ohos/hispark\_taurus为例，执行成功结果如下：
-
-    ```
-    ......
-    ohos ipcamera_hispark_taurus build success!
-    @ohos/hispark_taurus: distribution building completed.
-    ```
-
-
--   **自行安装docker（非Ubuntu环境）**
-
-    自行安装docker相关操作如下：
-
-    ```
-    # 拉取镜像 
-    docker pull swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker:0.0.3# linux环境下的编译 
-    hpm run distWithDocker solution={product}
-    # windows下的编译，需要配置gitbash 
-    hpm config set shellPath "gitbash路径"
-    hpm run distWithDocker solution={product}
-    ```

+### 搭建Docker环境-标准系统类设备（参考内存≥128MB）<a name="section13585262391"></a>
+
+**方式一：从HuaweiCloud SWR上直接获取Docker镜像进行构建：**
+
+1.  获取Docker镜像。
+
+    ```
+    docker pull swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.1
+    ```
+
+2.  进入OpenHarmony代码根目录执行如下命令，从而进入Docker构建环境。
+
+    ```
+    docker run -it -v $(pwd):/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.1
+    ```
+
+
+**方式二：通过Dockerfile 构建本地Docker镜像进行构建**
+
+1.  获取Dockerfile脚本文件，用来构建本地Docker镜像。
+
+    ```
+    git clone https://gitee.com/openharmony/docs.git
+    ```
+
+2.  进入Dockerfile代码目录路径执行Docker镜像构建命令。
+
+    ```
+    cd docs/docker/standard
+    ./build.sh
+    ```
+
+3.  进入OpenHarmony代码根目录执行如下命令，从而进入Docker构建环境。
+
+    ```
+    docker run -it -v $(pwd):/home/openharmony openharmony-docker-standard:0.0.1
+    ```
+
+
+### 编译源码-标准系统类设备（参考内存≥128MB）<a name="section193711513406"></a>
+
+1.  在源码的根目录执行预处理脚本。
+
+    ```
+    ../scripts/prepare.sh
+    ```
+
+2.  通过如下编译脚本启动标准系统类设备（参考内存≥128MB）的编译。
+
+    ```
+    ./build.sh --product-name {product_name}
+    ```
+
+    \{product\_name\}为当前版本支持的平台。比如：Hi3516DV300等。
+
+    编译所生成的文件都归档在out/ohos-arm-release/目录下，结果镜像输出在 out/ohos-arm-release/packages/phone/images/ 目录下。
+
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>退出Docker执行exit命令即可。
+
+## 基于HPM的Docker环境<a name="section485713518337"></a>
+
+docker\_dist是一个[HPM](https://hpm.harmonyos.com/)系统中的模板组件，能够帮助用户快速初始化HPM工程，利用docker镜像来快速编译OpenHarmony发行版，在很大程度上简化了编译前的环境配置。开发者在配置好Ubuntu和[hpm-cli](../bundles/bundles-guide-prepare.md)开发环境后，可以通过以下步骤来使用我们提供的Docker环境。
+
+### 搭建Docker环境<a name="section3295842510"></a>
+
+1.  初始化安装模板。在任意工作目录中执行以下命令。
+
+    ```
+    hpm init -t @ohos/docker_dist
+    ```
+
+2.  修改publishAs。
+
+    因为获取到的是模板类型的包，要把包的类型改为需要的类型。 在当前目录下打开bundle.json文件，把"publishAs"字段的值由"template"改为"distribution"。
+
+
+### 获取及编译源码<a name="section69141039143518"></a>
+
+执行编译。自动安装docker只能在Ubuntu环境下执行，如果其他环境，需要用户自行安装docker，然后拉取镜像，执行编译。
+
+-   **自动安装docker（Ubuntu环境）**
+
+    以下命令可以帮助用户自动安装docker, 拉取镜像，并且在容器中开始运行对应解决方案的拉取和编译。
+
+    **方式一：**
+
+    命令后接参数指定解决方案，格式如下：
+
+    ```
+    hpm run docker solution={product}
+    ```
+
+    \{product\}为需编译的解决方案，如：@ohos/hispark\_taurus、@ohos/hispark\_aries、@ohos/hispark\_pegasus。
+
+    **方式二：**
+
+    设置环境变量来选择解决方案，再执行编译命令。
+
+    1.  选择解决方案。
+
+        ```
+        export solution={product}
+        ```
+
+        \{product\}为需编译的解决方案，如：@ohos/hispark\_taurus、@ohos/hispark\_aries、@ohos/hispark\_pegasus。
+
+    2.  获取源码及执行编译。
+
+        ```
+        hpm run docker
+        ```
+
+
+    以上两种方式以@ohos/hispark\_taurus为例，执行成功结果如下：
+
+    ```
+    ......
+    ohos ipcamera_hispark_taurus build success!
+    @ohos/hispark_taurus: distribution building completed.
+    ```
+
+
+-   **自行安装docker（非Ubuntu环境）**
+
+    自行安装docker相关操作如下：
+
+    ```
+    # 拉取镜像 
+    docker pull swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker:0.0.3# linux环境下的编译 
+    hpm run distWithDocker solution={product}
+    # windows下的编译，需要配置gitbash 
+    hpm config set shellPath "gitbash路径"
+    hpm run distWithDocker solution={product}
+    ```
+
+

-# Input模型简介<a name="ZH-CN_TOPIC_0000001111681966"></a>
-
-Input驱动模型核心部分由设备管理层、公共驱动层、器件驱动层组成。其中：
-
--   设备管理层：主要为各类输入设备驱动提供input设备的注册、注销接口，同时统一管理input设备列表；
--   公共驱动层：负责对板级硬件进行初始化、硬件中断处理、向manager注册input设备等；
--   器件驱动层：通过适配平台驱动预留的差异化接口，实现器件驱动开发量最小化；
-
-此外，Input模型预先实现了数据通道以及设备配置信息解析等函数。
-
-关于Input模型的详细介绍请参考《[Touchscreen开发概述](../driver/Touchscreen开发概述.md)》。

-基于Input模型适配一款触摸屏IC需要完成的工作有：
-
-1.配置设备描述信息。驱动注册到HDF框架所需要的设备驱动描述信息，如驱动是否加载以及加载次序等；
-
-2.配置器件私有信息、平台硬件信息。器件私有信息包括上下电时序等，平台硬件信息包括器件连接主板的GPIO端口信息等。
-
-3.适配器件私有驱动。 Input模型对Input设备开发流程进行了抽象，开发者只需要适配器件驱动层，无需改动管理驱动层以及公共驱动层。

+        void OnCreateFailed(const std::string cameraId, int32_t errorCode) override {}
+        void OnReleased(Camera &c) override {}
+    };
+    ```
+
+4.  创建CameraKit，用于创建和获取camera信息。
+
+    ```
+    CameraKit *camKit = CameraKit::GetInstance();
+    list<string> camList = camKit->GetCameraIds();
+    string camId;
+    for (auto &cam : camList) {
+        cout << "camera name:" << cam << endl;
+        const CameraAbility *ability = camKit->GetCameraAbility(cam);
+        /* find camera which fits user's ability */
+        list<CameraPicSize> sizeList = ability->GetSupportedSizes(0);
+        if (find(sizeList.begin(), sizeList.end(), CAM_PIC_1080P) != sizeList.end()) {
+            camId = cam;
+            break;
+        }
+    }
+    ```
+
+5.  创建Camera实例。
+
+    ```
+    EventHandler eventHdlr; // Create a thread to handle callback events
+    SampleCameraStateMng CamStateMng(eventHdlr);
+    
+    camKit->CreateCamera(camId, CamStateMng, eventHdlr);
+    ```
+
+6.  根据[步骤1](#zh-cn_topic_0000001052170554_li378084192111)、[步骤2](#zh-cn_topic_0000001052170554_li8716104682913)、[步骤3](#zh-cn_topic_0000001052170554_li6671035102514)中的回调设计，camera实例创建成功后会进行配置操作，主流程中app需要设计同步机制。
+
+    ```
+    void OnCreated(Camera &c) override
+    {
+        cout << "Sample recv OnCreate camera." << endl;
+        auto config = CameraConfig::CreateCameraConfig();
+        config->SetFrameStateCallback(&fsCb_, &eventHdlr_);
+        c.Configure(*config);
+        cam_ = &c;
+    }
+    
+    void Capture()
+    {
+        if (cam_ == nullptr) {
+            cout << "Camera is not ready." << endl;
+            return;
+        }
+        FrameConfig *fc = new FrameConfig(FRAME_CONFIG_CAPTURE);
+        Surface *surface = Surface::CreateSurface();
+        if (surface == nullptr) {
+            delete fc;
+            return;
+        }
+        surface->SetWidthAndHeight(1920, 1080); /* 1920:width,1080:height */
+        fc->AddSurface(*surface);
+        cam_->TriggerSingleCapture(*fc);
+    }
+    ```

+
+本示例将运行源码中的camera示例代码，通过本示例可以实现对开发板拍照、录像及预览功能的控制。
+
+-   本示例源码路径为“applications/sample/camera/media/camera\_sample.cpp”。
+-   在运行本示例前需先完成编译烧录、运行镜像等步骤，相关操作请参考[Hi3516快速入门](../quick-start/quickstart-lite-introduction-hi3516.md#section26131214194212)。
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >开发板启动后默认会加载launcher应用，应用的图形界面默认显示在媒体图层上方，会影响camera\_sample的演示结果，因此需要在编译或是打包时去掉launcher应用。
+    >**修改方法：**将“build/lite/components/applications.json”中camera\_sample\_app组件的targets中"//applications/sample/camera/launcher:launcher\_hap"整行注释或删除。
+
+-   本示例编译结果路径为“out/hi3516dv300/ipcamera\_hi3516dv300\_liteos/dev\_tools/bin”，为让文件能在单板中执行，可将示例文件通过读卡器复制至TF卡中，或者修改camera\_sample的编译脚本将结果文件复制至rootfs.img中。
+
+    修改源码路径“applications/sample/camera/media/BUILD.gn”中第一处的output\_dir。
+
+    -   修改前：output\_dir = "$root\_out\_dir/dev\_ools"
+    -   修改后：output\_dir = "$root\_out\_dir/"
+
+    重新执行源码仓编译并烧写入单板后，可在单板bin目录下找到camera\_sample文件。
+
+    >![](../public_sys-resources/icon-notice.gif) **须知：** 
+    >实例运行拍照和录像功能需要插入TF卡\(最大容量支持128GB\)，系统启动后自动将TF卡挂载至/sdcard目录，如果在启动后插入则需要手动挂载。查看拍照和录像内容可将TF卡中内容复制到电脑中进行查看，预览功能无需TF卡。
+
+-   接下来可通过以下步骤运行示例：
+
+1.  通过cd命令进入可执行程序的末端路径，启动camera\_sample，执行命令如下图。
+
+    **图 1**  启动示例<a name="fig380985885020"></a>  
+    ![](figure/启动示例.png "启动示例")
+
+    运行后的控制命令如串口打印所示，按s键停止当前操作（包括录像和预览），按q键退出示例程序。
+
+2.  按1进行拍照，拍照的文件格式为jpg，存储在/sdcard，文件名Capture\*
+
+    **图 2**  输入拍照指令后串口打印日志<a name="fig17819185018384"></a>  
+    ![](figure/输入拍照指令后串口打印日志.png "输入拍照指令后串口打印日志")
+
+    若想查看保存文件，可在退出程序后进入文件系统查看，退出后重新进入请回到步骤1。

+# 开发首页<a name="ZH-CN_TOPIC_0000001054927705"></a>
+
+应用首页主要展示城市的空气质量概况。首页总共有两屏（可以根据需求设置多屏），每屏显示一个城市的空气质量信息：主要包括AQI指数、城市名称、污染物指数、更新时间和信息来源等数据。
+
+从第一章节中的[显示效果图](device-camera-visual-overview.md#fig18250512195914)分析可知，首页由三部分组成：
+
+-   标题栏：位于页面正上方，位置固定，包括应用退出按钮和页面标题。
+-   信息栏：主要展示城市的空气信息指标等内容；该页面根据用户需求可设置多屏，且能循环滑动。
+-   页面位置指示器：主要功能是标识当前页面，位置固定在页面底部的中间。
+
+综上，我们可搭建一个纵向三行排列的弹性页面布局来实现首页的功能。
+
+1.  在hml文件中添加一个根节点div，注意每个hml文件中有且只能有一个根节点，代码如下：
+
+    ```
+    <div class="container">
+    </div>
+    ```
+
+    class="container"表示组件使用的样式，container是index.css文件中的一个样式类，代码如下：
+
+    ```
+    .container {    
+        flex-direction: column;
+        height: 480px;
+        width: 960px;
+    }
+    ```
+
+    在这个样式类中，我们分别设置了根组件div的高度和宽度（注意在应用的开发过程中，除部分组件（text）外必须显式指定组件的高度和宽度，否则可能无法显示）、并将flex-direction属性设置为column，该属性表示div的子组件是垂直方向从上到下排列；这样就可以实现本节开头所说的纵向三行排列的弹性页面布局。
+
+2.  实现标题栏：标题栏包括一个退出按钮和一个标题，两个控件是横向排列；首先添加一个div，并设置flex-direction的属性为row，表示子组件是水平方向从左往右排列；然后依次添加一个image和text组件，代码如下：
+
+    ```
+    <div class="container">    
+        <div class="header" onclick="exitApp">        
+            <image class="back" src="common/ic_back.png"></image>        
+            <text class="title">            
+                空气质量        
+             </text>    
+        </div>
+    </div>
+    ```
+
+    设置组件的高度、边距、颜色等属性。
+
+    ```
+    .header {    
+        width: 960px;
+        height: 72px;
+    }
+    .back {    
+        width: 36px;
+        height: 36px;
+        margin-left: 39px;
+        margin-top: 23px;
+    }
+    .title {    
+        width: 296px;
+        height: 40px;
+        margin-top: 20px;
+        margin-left: 21px;
+        color: #e6e6e6;
+    }
+    ```
+
+    onclick="exitApp" 设置了div组件的click事件，当在标题栏上触发点击事件时，就会执行函数exitApp，该函数位于index.js文件中，代码如下：
+
+    ```
+    exitApp() {  
+        console.log('start exit');  
+        app.terminate();  
+        console.log('end exit');
+    }
+    ```
+
+    app.terminate\(\)函数实现了程序退出功能；在使用该函数前，需要引入app模块，在js文件的最上方写如下代码：
+
+    ```
+    import app from '@system.app'
+    ```
+
+    代码编写完成后，在模拟器中运行项目，显示效果如下图所示：
+
+    **图 1**  标题栏效果<a name="fig14273162465317"></a>  
+    ![](figure/标题栏效果.png "标题栏效果")
+
+3.  实现城市空气质量信息的多屏左右滑动，需要使用“swiper”组件。
+
+    在根节点中添加一个子节点swiper，代码片段如下：
+
+    ```
+    <div class="container">    
+        <div class="header" onclick="exitApp">        
+            <image class="back" src="common/ic_back.png"></image>        
+            <text class="title">            
+                空气质量        
+            </text>    
+        </div>    
+        <swiper class="swiper" index="{{swiperPage}}" duration="500" onchange="swiperChange">
+        </swiper>
+    </div>
+    ```
+
+    -   class="swiper"设置了组件的高度和宽度，代码如下：
+
+        ```
+        .swiper {
+            height: 385px;
+            width: 960px;
+        }
+        ```
+
+
+    -   index="\{\{swiperPage\}\}" duration="500" onchange="swiperChange" 这些代码用来设置组件的属性和事件。其中，duration="500" 表示设置swiper的页面滑动的动画时长为500ms。
+    -   index="\{\{swiperPage\}\}"设置了swiper子组件索引值，\{\{swiperPage\}\}这种写法表示index的值是和js代码中的swiperPage变量动态绑定的，index的值会随着swiperPage变动而改变。
+    -   onchange="swiperChange" 设置了swiper组件的change事件和函数swiperChange绑定，对应的js代码如下：
+
+        ```
+        //引入router模块，用户页面跳转
+        import router from'@system.router'
+        import app from '@system.app'
+        
+        export default {
+            //定义参数
+            data: {
+              //默认是第一页
+              swiperPage: 0 
+            },
+            onInit () {
+            },
+            exitApp(){  
+                console.log('start exit');  
+                app.terminate();  
+                console.log('end exit');
+            },
+            //swiper滑动回调事件，保存当前swiper的index值，每次滑动都会将index值保存在swiperPage变量中
+            swiperChange (e) {
+                this.swiperPage = e.index;
+            }
+        }
+        ```
+
+
+4.  设置一个城市的空气质量信息为一屏，在一屏内，要展示多种信息，分别使用不同的控件进行展示。
+
+    在swiper中添加两个子组件stack（绝对布局），每个stack组件内分别添加text、image、progress等组件来显示对应的信息 ，页面结构如下：
+
+    ```
+     <swiper class="swiper" index="{{swiperPage}}" duration="500" onchange="swiperChange">
+        <!--第一屏-->
+        <stack class="swiper">
+            <text></text>------空气质量
+            <text></text>------城市名称
+            <progress></progress>-----进度条
+            <image></image>-------云朵图片
+            <text></text>--------AQI数值
+            <text>AQI</text>------AQI
+            <div>--------空气指标详细信息
+            </div>
+            <div>--------更新时间和网站等信息
+            </div>
+        </stack>
+        <!--第二屏-->
+        <stack class="container">
+            <text></text>
+            <text></text>
+            <progress></progress>
+            <image></image>
+            <text></text>
+            <text></text>
+            <div></div>    
+        </stack>
+    </swiper>
+    ```
+
+    代码编写完成后，模拟器运行效果如下：
+
+    **图 2**  标题栏和信息栏效果<a name="fig177003454238"></a>  
+    ![](figure/标题栏和信息栏效果.png "标题栏和信息栏效果")
+
+5.  添加页面位置指示器：由于当前swiper不支持设置indicator，需要开发者自己来实现该效果。在根节点中添加一个子组件div，并设置相应样式；然后在该div中添加两个子组件div，设置两个div的border-radius，并在swiper滑动事件中动态改变对应div的背景色来实现该效果。
+
+    ```
+    <div class="images">    
+        <div class="circle-div" style="background-color: {{iconcheckedColor}};"></div>    
+        <div class="circle-div" style="background-color: {{iconUncheckedColor}};margin-left: 36px;"></div>
+    </div>
+    ```

+    ![](figure/页面位置指示器效果图.png "页面位置指示器效果图")
+
+6.  所有组件设置样式、动画效果和数据动态绑定，完整代码如下所示：
+
+    -   **index.hml文件**
+
+    ```
+    <div class="container">
+        <div class="header" onclick="exitApp">
+            <image class="back" src="common/ic_back.png"></image>
+            <text class="title">
+                空气质量
+            </text>
+        </div>
+        <swiper class="swiper" index="{{swiperPage}}" duration="500" onchange="swiperChange">
+            <stack class="swiper">

+                </text>
+                <progress class="circle-progress" style="color: {{textColor1}};background-Color: {{bgColor1}};" type="arc"
+                        percent="{{percent1}}"></progress>
+                <image class="image" src="{{src1}}"></image>
+                <text class="aqi-value">{{airData[0].detailData}}
+                </text>
+                <text class="aqi">
+                    AQI

+    -   **index.css文件**
+
+    css文件中定义了许多class，每个class用于定义组件的位置、大小、字体、颜色、背景色等信息。同时，每一个子组件都叠加在父组件中，父组件的样式会影响子组件的呈现。

+
+
+## 概述<a name="section11522349121115"></a>
+
+本文将介绍如何快速搭建基于OpenHarmony标准系统（Hi3516DV300开发板）的应用开发环境，并基于一个时钟APP示例逐步展示应用的创建、开发、调试和安装等流程。示例代码可以通过[本链接](https://gitee.com/openharmony/app_samples/tree/master/common/Clock)获取。
+
+时钟App是一款显示实时时间的应用，显示效果如下图所示：
+
+**图 1**  时钟应用显示效果图<a name="fig7763172132019"></a>  
+
+
+![](figure/Clock.png)
+
+## 开发准备<a name="section6592121861218"></a>
+
+首先需要下载和配置DevEco Studio，具体操作请参考[DevEco Studio 使用指南](../../application-dev/quick-start/DevEco-Studio（OpenHarmony）使用指南.md)。
+
+## 开发步骤<a name="section19901741111312"></a>
+
+应用的功能是通过表盘和数字显示实时时间。
+
+从[显示效果图](device-clock-guide.md#fig7763172132019)分析可知，页面由两个部分组成：
+
+-   表盘栏：主要展示一个动态的钟表，且钟表指针能准确转动。
+-   数字时间栏：主要以数字形式显示当前时间。
+
+综上，我们可搭建一个纵向两行排列的弹性页面布局来实现界面的功能。具体开发步骤如下：
+
+1.  在hml文件中添加一个根节点div，注意每个hml文件中有且只能有一个根节点，代码如下：
+
+    ```
+    <div class="container">
+    </div>
+    ```
+
+    class="container"表示组件使用的样式，container是index.css文件中的一个样式类，代码如下：
+
+    ```
+    .container {     
+        flex-direction: column;
+        justify-content: center;
+        align-items: center;
+        width: 100%;
+        height: 100%;
+    }
+    ```
+
+    在这个样式类中，我们分别设置了根组件div的高度和宽度（注意在应用的开发过程中，除部分组件（text）外必须显式指定组件的高度和宽度，否则可能无法显示）、并将flex-direction属性设置为column，该属性表示div的子组件是垂直方向从上到下排列；这样就可以实现本节开头所说的纵向两行排列的弹性页面布局。
+
+2.  实现时钟转动，需要使用“stack”组件。“stack”组件的功能是堆叠容器，子组件按照顺序依次入栈，后一个子组件覆盖前一个子组件。
+
+    在根组件下添加一个stack容器，代码片段如下：
+
+    ```
+    <div class="container">    
+        <stack class="stack">
+            <image src="/common/clock_bg.png" class="clock-bg"></image> <!--设置表盘图片-->
+            <image src="/common/hour_hand.png" class="clock-hand"
+                   style="transform : rotate({{ hour * 30 + minute / 2 }}deg);"></image> <!--设置时钟图片，(hour * 30)一小时旋转30度，(minute / 2)时钟每分钟旋转的角度-->
+            <image src="/common/minute_hand.png" class="clock-hand"
+                   style="transform : rotate({{ minute * 6 + second / 10 }}deg);"></image> <!--设置分钟图片，(minute * 6)一分钟旋转6度，(second / 10)分钟每秒钟旋转的角度-->
+            <image src="/common/second_hand.png" class="clock-hand"
+                   style="transform : rotate({{ second * 6 }}deg);"></image> <!--设置秒钟图片，(second * 6)一秒旋转6度-->
+       </stack>
+    </div>
+    ```
+
+    style="transform : rotate\(\{\{ second \* 6 \}\}deg\) 这类代码用来设置组件的旋转事件。其中transform是设置动画平移/旋转/缩放的属性，rotate是旋转动画属性，支持设置x轴和y轴两个维度的选中参数。
+
+    在css文件中设置"stack"组件样式的高度、宽度、位置等属性，代码如下：
+
+    ```
+    .stack {
+        flex-direction: column;
+        justify-content: center;
+        align-items: center;
+        width: 100%;
+        height: 50%;
+    }
+    ```
+
+    在css文件中设置"clock-bg"组件样式的高度、宽度等属性，代码如下：
+
+    ```
+    .clock-bg {
+        width: 80%;
+        height: 80%;
+        object-fit: scale-down;
+    }
+    ```
+
+    在css文件中设置"clock-hand"组件为时针、分针和秒针的高度、宽度等属性，代码如下：
+
+    ```
+    .clock-hand {
+        width: 25%;
+        height: 65%;
+        object-fit: contain;
+    }
+    ```
+
+    index.js中会有一个定时器实时刷新时分秒变量，从而触发时间界面自动更新。对应的js代码如下：
+
+    ```
+    export default {
+        timer: undefined,
+        //定义参数
+        data: {
+          hour: 0,   //定义小时
+          minute: 0, //定义分钟
+          second: 0  //定义秒
+        },
+        onInit () {
+            this.updateTime();
+            this.timer = setInterval(this.updateTime, 1000)//设置1s的定时器
+        },  
+        updateTime: function () {       
+            var nowTime = new Date()    
+            this.hour = nowTime.getHours()    
+            this.minute = nowTime.getMinutes()   
+            this.second = nowTime.getSeconds()    
+            if (this.hour < 10) {        
+                this.hour = '0' + this.hour    
+            }  
+            if (this.minute < 10) {       
+                this.minute = '0' + this.minute   
+            }    
+            if (this.second < 10) {      
+                this.second = '0' + this.second   
+            }
+        },
+    }
+    ```
+
+3.  显示数字时间，在钟表下面以数字形式显示当前时间。在根布局内末尾加上text组件，页面结构如下：
+
+    ```
+    <text class="digit-clock"> {{ hour }}:{{ minute }}:{{ second }}</text>
+    ```
+
+    class="digit-clock"设置了组件的高度和宽度以及字体大小，其代码如下：
+
+    ```
+    .digit-clock {    
+        font-size: 58px;   
+        width: 100%;
+        margin-top: 0px;
+        text-align: center;
+    }
+    ```
+
+4.  所有组件设置样式、动画效果和数据动态绑定，完整代码如下所示：
+    -   **index.hml文件**
+
+        ```
+        <div class="container">
+            <stack class="stack">
+                <image src="/common/clock_bg.png" class="clock-bg"></image>
+                <image src="/common/hour_hand.png" class="clock-hand"
+                       style="transform : rotate({{ hour * 30 + minute / 2 }}deg);"></image>
+                <image src="/common/minute_hand.png" class="clock-hand"
+                       style="transform : rotate({{ minute * 6 + second / 10 }}deg);"></image>
+                <image src="/common/second_hand.png" class="clock-hand"
+                       style="transform : rotate({{ second * 6 }}deg);"></image>
+            </stack>
+            <text class="digit-clock">{{ hour }}:{{ minute }}:{{ second }}</text>
+        </div>
+        ```
+
+
+    -   **index.css文件**
+
+        ```
+        .container {
+            flex-direction: column;
+            justify-content: center;
+            align-items: center;
+            width: 100%;
+            height: 100%;
+        }
+        
+        .stack {
+            flex-direction: column;
+            justify-content: center;
+            align-items: center;
+            width: 100%;
+            height: 50%;
+        }
+        
+        .digit-clock {
+            font-size: 58px;
+            width: 100%;
+            margin-top: 0px;
+            text-align: center;
+        }
+        
+        .clock-bg {
+            width: 80%;
+            height: 80%;
+            object-fit: scale-down;
+        }
+        
+        .clock-hand {
+            width: 25%;
+            height: 65%;
+            object-fit: contain;
+        }
+        ```
+
+
+    -   **index.js:**
+
+        js文件主要用于实现App应用的逻辑交互。在本页面js文件中，需要实现如下功能：定时获取系统时间。
+
+        ```
+        export default {
+            timer: undefined,
+            data: {
+                hour: 0,
+                minute: 0,
+                second: 0
+            },
+            onInit() {
+                this.updateTime()
+                this.timer = setInterval(this.updateTime, 1000)
+            },
+            updateTime: function () {
+                var nowTime = new Date()
+                this.hour = nowTime.getHours()
+                this.minute = nowTime.getMinutes()
+                this.second = nowTime.getSeconds()
+                if (this.hour < 10) {
+                    this.hour = '0' + this.hour
+                }
+                if (this.minute < 10) {
+                    this.minute = '0' + this.minute
+                }
+                if (this.second < 10) {
+                    this.second = '0' + this.second
+                }
+            },
+            onDestroy() {
+                clearInterval(this.timer);
+            }
+        }
+        ```
+
+
+
+## 签名打包<a name="section10601181101516"></a>
+
+代码编写完成后，在真机设备上运行应用，需要先对应用进行签名，然后再进行打包，具体操作请参考[签名打包指导](../../application-dev/quick-start/配置OpenHarmony应用签名信息.md)。
+
+## 真机运行<a name="section092721731511"></a>
+
+应用签名打包后即可安装到开发板。安装应用前需要先完成[DevEco Device Tool的安装配置](https://device.harmonyos.com/cn/docs/ide/user-guides/service_introduction-0000001050166905)，然后将OpenHarmony系统烧录到开发板并运行。编译烧录、运行镜像的基本操作请参考快速入门手册：[标准系统Hi3516快速入门](../quick-start/quickstart-standard.md)。完成镜像运行，系统正常启动后，执行如下步骤安装或卸载应用。
+
+1.  从开发者工具代码仓路径中获取hdc客户端。
+
+    ```
+    developtools/hdc_standard/prebuilt/windows/hdc_std.exe
+    ```
+
+    修改名称为hdc.exe，并将工具路径加入系统环境path变量中。
+
+2.  启动cmd命令窗口，执行以下命令，推送hap应用包到设备目录下并安装。
+
+    ```
+    hdc smode
+    hdc target mount
+    hdc file send clock.hap /data/clock.hap
+    hdc shell chmod 666 /data/clock.hap
+    hdc shell bm install -p /data/clock.hap
+    ```
+
+3.  启动应用。执行以下命令，其中ohos.samples.clock为应用包名，MainAbility为应用启动的Ability。
+
+    ```
+    hdc shell aa start -d 123 -a ohos.samples.clock.MainAbility -b ohos.samples.clock
+    ```
+
+4.  卸载应用（可选）。执行以下命令，其中ohos.samples.clock为应用包名。
+
+    ```
+    hdc shell bm uninstall -n ohos.samples.clock
+    ```
+

+
+### hdc\_std连接不到设备<a name="section1922725151614"></a>
+
+-   **现象描述**
+
+    执行 "hdc\_std list targets"命令后结果为：\[Empty\]
+
+-   **可能原因和解决方法**
+    1.  设备没有被识别：
+
+        在设备管理器中查看是否有hdc设备，在通用串行总线设备中会有“HDC Device”信息。如果没有，hdc无法连接。此时需要插拔设备，或者烧写最新的镜像。
+
+    2.  hdc\_std工作异常：
+
+        可以执行"hdc kill"或者"hdc start -r"杀掉hdc服务或者重启hdc服务，然后再执行hdc list targets查看是否已经可以获取设备信息。
+
+    3.  hdc\_std与设备不匹配：
+
+        如果设备烧写的是最新镜像，hdc\_std也需要使用最新版本。由于hdc\_std会持续更新，请从开源仓developtools\_hdc\_standard中获取，具体位置在该开源仓的prebuilt目录。
+
+
+
+### hdc\_std运行不了<a name="section15657547131615"></a>
+
+-   **现象描述**
+
+    点击hdc\_std.exe文件无法运行。
+
+-   **可能原因和解决方法**
+
+    hdc\_std.exe不需要安装，直接放到磁盘上就能使用，也可以添加到环境变量中。通过打开cmd执行hdc\_std命令直接使用。

+## 概述<a name="section194201316174215"></a>
+
+本文档将以I2C驱动为例，介绍如何基于HDF驱动框架完成平台驱动开发。
+
+>![](../public_sys-resources/icon-caution.gif) **注意：** 
+>本例仅作为平台驱动开发示例参考，开发者不可直接用于商用集成。
+
+HDF驱动框架为常用外围设备提供了标准的驱动框架，驱动开发者只需将驱动适配至HDF驱动框架，即可通过HDF驱动框架提供的接口操作外围设备。
+
+本文以I2C为例。其时序流程如[图1](#fig148041484161)所示。

+
+### 实例化驱动入口<a name="section85325864412"></a>
+
+实例化一个HdfDriverEntry 对象作为驱动入口。驱动入口必须为HdfDriverEntry（在hdf\_device\_desc.h中定义）类型的全局变量，且moduleName要和device\_info.hcs中保持一致。在加载驱动时HDF框架会先调用Bind函数，再调用Init函数加载该驱动，当Init调用异常时，HDF框架会调用Release释放驱动资源并退出。
+
+I2C驱动中没有实现Bind方法，因为I2C控制器由manager管理，而在manager中已经实现了Bind方法，因此I2C驱动中无需再绑定服务。
+
+实例化驱动入口的示例代码如下：
+
+```
+/* 定义驱动入口的对象，必须为HdfDriverEntry（在hdf_device_desc.h中定义）类型的全局变量 */
+struct HdfDriverEntry g_sampleI2cDriverEntry = {
+    .moduleVersion = 1,
+    .Init = SampleI2cInit,
+    .Release = SampleI2cRelease,
+    .moduleName = "demo_i2c_driver",
+};
+/* 调用HDF_INIT将驱动入口注册到HDF框架中 */
+HDF_INIT(g_sampleI2cDriverEntry);
+```
+
+### 设置相关参数<a name="section8155172019453"></a>
+
+通过配置device\_info.hcs，并从HCS获取并解析设备的配置参数以确保驱动能够正确加载。
+
+1.  添加设备服务节点（必选）。
+
+    编辑device\_info.hcs，在device\_i2c :: device下添加驱动设备服务节点，示例如下：
+
+    ```
+     root {
+        device_info {
+            match_attr = "hdf_manager";
+                device_i2c :: device {                        // i2c设备节点
+    		device2 :: deviceNode {                   // i2c驱动的DeviceNode节点
+                        policy = 0;                           // policy字段是驱动服务发布的策略
+                        priority = 55;                        // 驱动启动优先级
+                        permission = 0644;                    // 驱动创建设备节点权限
+                        moduleName = "demo_i2c_driver";       // 驱动名称，该字段的值必须和驱动入口结构的moduleName值一致
+                        serviceName = "DEMO_I2C_DRIVER";      // 驱动对外发布服务的名称，必须唯一
+                        deviceMatchAttr = "demo_i2c_config";  // 驱动私有数据匹配的关键字，必须和驱动私有数据配置表中的
+                                                              // match_attr值相等
+                    }
+                }
+        }
+    }
+    
+    ```
+
+    >![](../public_sys-resources/icon-notice.gif) **须知：** 
+    >配置文件中的priority（取值范围为整数0到200）是用来表示host和驱动的优先级，不同的host内的驱动，host的priority值越小，驱动加载优先级越高；同一个host内驱动的priority值越小，加载优先级越高，驱动的priority值相同则不保证加载顺序。
+
+2.  添加配置参数（可选）。
+
+    有时驱动可能会需要私有配置信息，以确保寄存器的配置可以满足不同产品的需求。如需要私有配置信息，则可以添加一个驱动的配置文件，用来存放一些驱动的默认配置信息，HDF框架在加载驱动的时候，会将对应的配置信息获取并保存在HdfDeviceObject 中的property里面，通过Bind和Init（参考[驱动开发](../driver/drive-hdf-development.md)）传递给驱动。驱动开发者可新建配置文件，并在板级驱动hdf.hcs中引用新建的配置文件，本例中直接在原有的配置文件i2c\_config.hcs内添加配置参数。
+
+    本例中编辑i2c\_config.hcs，添加配置参数：
+
+    ```
+    root {
+        platform {
+                i2c_config_demo {                
+                match_attr = "demo_i2c_config";        // 该字段的值必须和device_info.hcs中的deviceMatchAttr值一致
+    
+                template i2c_controller {              // 参数模板
+                    bus = 0;
+                    reg_pbase = 0x120b0000;
+                    reg_size = 0xd1;
+                }
+    
+                controller_demo_0 :: i2c_controller {  // 两个I2C示例控制器
+                    bus = 8;
+                }
+                controller_demo_1 :: i2c_controller {
+                    bus = 9;
+                }
+            }
+        }
+    }
+    ```
+
+    match\_attr字段必须与device\_info.hcs中的deviceMatch\_Attr保持一致，在此文件中配置驱动需要的参数，通过match\_attr可匹配至对应的驱动，该驱动即可在Bind或Init中调用DeviceResourceGetIfaceInstance\(\)函数获取这些配置参数。
+
+    若配置文件为新文件，则需要在板级配置入口文件hdf.hcs中引用该配置文件，例如：
+
+    ```
+    #include "device_info/device_info.hcs"
+    #include "i2c/i2c_config.hcs"
+    ```
+
+    由于本例中在原有的i2c\_config.hcs内添加配置参数，没有新建配置文件，因此无需再将i2c\_config.hcs添加至板级配置入口文件中。
+
+3.  驱动从HCS获取配置参数。
+
+    在本例中，驱动需要通过HCS获取寄存器物理基地址、寄存器大小、总线号等参数，从而对控制器进行正确配置。
+
+    ```
+    /* 从HCS获取配置参数 */
+    static int32_t SampleI2cReadDrs(struct SampleI2cCntlr *sampleCntlr, const struct DeviceResourceNode *node)
+    {
+        int32_t ret;
+        struct DeviceResourceIface *drsOps = NULL;
+    
+        drsOps = DeviceResourceGetIfaceInstance(HDF_CONFIG_SOURCE);
+        if (drsOps == NULL || drsOps->GetUint32 == NULL) {                         // 确保GetUint32方法可用
+            HDF_LOGE("%s: invalid drs ops fail!", __func__);
+            return HDF_FAILURE;
+        }
+    
+        ret = drsOps->GetUint32(node, "reg_pbase", &sampleCntlr->regBasePhy, 0);   // 从HCS读取物理基地址reg_pbase
+        if (ret != HDF_SUCCESS) {
+            HDF_LOGE("%s: read regBase fail!", __func__);
+            return ret;
+        }
+    
+        ret = drsOps->GetUint16(node, "reg_size", &sampleCntlr->regSize, 0);       // 从HCS读取寄存器大小reg_size
+        if (ret != HDF_SUCCESS) {
+            HDF_LOGE("%s: read regsize fail!", __func__);
+            return ret;
+        }
+    
+        ret = drsOps->GetUint16(node, "bus", (uint16_t *)&sampleCntlr->bus, 0);    // 从HCS读取总线号bus
+        if (ret != HDF_SUCCESS) {
+            HDF_LOGE("%s: read bus fail!", __func__);
+            return ret;
+        }
+    
+        return HDF_SUCCESS;
+    }
+    ```
+
+
+### 添加控制器<a name="section1335374114452"></a>
+
+初始化控制器硬件，并调用核心层接口完成向核心层添加、删除设备，以及钩子函数的实现等。
+
+1.  定义结构体，实现钩子函数并赋值至函数指针。
+
+    I2cMethod结构体在i2c\_core.h中定义，其中通过函数指针的方式定义了I2C需要实现的方法，transfer方法为用于传输的钩子函数，在驱动中需要做具体实现并对函数指针赋值。
+
+    示例代码如下：
+
+    ```
+    /* 自定义设备结构体，继承父类I2cCntlr */
+    struct SampleI2cCntlr {
+        struct I2cCntlr cntlr;
+        OsalSpinlock spin;
+        volatile unsigned char  *regBase;
+        uint16_t regSize;
+        int16_t bus;
+        uint32_t regBasePhy;
+    };
+    
+    /* 消息结构体，继承父类I2cMsg */
+    struct SampleTransferData {
+        struct I2cMsg *msgs;
+        int16_t index;
+        int16_t count;
+    };
+    /* 钩子函数实现 */
+    static int32_t SampleI2cTransfer(struct I2cCntlr *cntlr, struct I2cMsg *msgs, int16_t count)
+    {
+        int32_t ret = HDF_SUCCESS;
+        struct SampleI2cCntlr *sampleCntlr = NULL;
+        struct SampleTransferData td;
+    
+        if (cntlr == NULL || cntlr->priv == NULL) {
+            HDF_LOGE("SampleI2cTransfer: cntlr lor sampleCntlr is null!");
+            return HDF_ERR_INVALID_OBJECT;
+        }
+        sampleCntlr = (struct SampleI2cCntlr *)cntlr;
+    
+        if (msgs == NULL || count <= 0) {
+            HDF_LOGE("SampleI2cTransfer: err parms! count:%d", count);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        td.msgs = msgs;
+        td.count = count;
+        td.index = 0;
+    
+        HDF_LOGE("Successfully transmitted!");  // 表示此处传输成功
+          
+        td.index = count;                       // 经过处理，最后实际发送msg个数等于count，返回已发送个数，此句代替已省略的处理过程
+        return (td.index > 0) ? td.index : ret;
+    }
+    /* 钩子函数赋值 */
+    static struct I2cMethod g_method = {
+        .transfer = SampleI2cTransfer,
+    };
+    ```
+
+2.  编写驱动初始化函数。
+
+    本例中使用SampleI2cInit作为驱动初始化函数的函数名（函数名称可由驱动开发者确定），该函数需要在驱动入口结构体中赋值给Init，以供HDF驱动框架调用从而达到初始化驱动的目的。该函数中需要对从HCS获取的配置参数进行解析，并按照这些参数创建控制器。示例如下：
+
+    ```
+    /* 解析参数，申请内存并创建控制器 */
+    static int32_t SampleI2cParseAndInit(struct HdfDeviceObject *device, const struct DeviceResourceNode *node)
+    {
+        int32_t ret;

+            sampleCntlr = NULL;
+        }
+        return ret;
+    }
+    /* 驱动入口初始化函数 */
+    static int32_t SampleI2cInit(struct HdfDeviceObject *device)
+    {
+        int32_t ret;
+        const struct DeviceResourceNode *childNode = NULL;
+    
+        HDF_LOGE("%s: Enter", __func__);
+        if (device == NULL || device->property == NULL) {
+            HDF_LOGE("%s: device or property is NULL", __func__);
+            return HDF_ERR_INVALID_OBJECT;
+        }
+    
+        ret = HDF_SUCCESS;

+            ret = SampleI2cParseAndInit(device, childNode);    // 调用解析参数和创建控制器的函数
+            if (ret != HDF_SUCCESS) {
+                break;
+            }
+        }
+        return ret;
+    }
+    ```
+
+3.  编写驱动释放函数。
+
+    本例中使用SampleI2cRelease作为驱动释放函数的函数名（函数名称可由驱动开发者确定），该函数需要在驱动入口结构体中赋值给Release，当HDF框架调用Init函数初始化驱动失败时，将调用Release释放驱动资源。该函数中需包含释放内存和删除控制器等操作。示例如下：
+
+    ```
+    /* 删除控制器函数 */
+    static void SampleI2cRemoveByNode(const struct DeviceResourceNode *node)
+    {
+        int32_t ret;
+        int16_t bus;
+        struct I2cCntlr *cntlr = NULL;
+        struct SampleI2cCntlr *sampleCntlr = NULL;
+        struct DeviceResourceIface *drsOps = NULL;
+    
+        drsOps = DeviceResourceGetIfaceInstance(HDF_CONFIG_SOURCE);
+        if (drsOps == NULL || drsOps->GetUint32 == NULL) {
+            HDF_LOGE("%s: invalid drs ops fail!", __func__);
+            return;
+        }
+    
+        ret = drsOps->GetUint16(node, "bus", (uint16_t *)&bus, 0); // 从HCS获取I2C总线号
+        if (ret != HDF_SUCCESS) {
+            HDF_LOGE("%s: read bus fail!", __func__);
+            return;
+        }
+    
+        cntlr = I2cCntlrGet(bus);
+        if (cntlr != NULL && cntlr->priv == node) {                // 根据I2C总线号删除控制器
+            I2cCntlrPut(cntlr);
+            I2cCntlrRemove(cntlr);
+            sampleCntlr = (struct SampleI2cCntlr *)cntlr;
+            OsalIoUnmap((void *)sampleCntlr->regBase);
+            OsalMemFree(sampleCntlr);
+        }
+        return;
+    }
+    /* 释放资源 */
+    static void SampleI2cRelease(struct HdfDeviceObject *device)
+    {
+        const struct DeviceResourceNode *childNode = NULL;
+    
+        HDF_LOGI("%s: enter", __func__);
+    
+        if (device == NULL || device->property == NULL) {
+            HDF_LOGE("%s: device or property is NULL", __func__);
+            return;
+        }
+    
+        DEV_RES_NODE_FOR_EACH_CHILD_NODE(device->property, childNode) {
+            SampleI2cRemoveByNode(childNode);                       // 调用删除控制器函数
+        }
+    }
+    ```
+
+
+## 编译及烧录<a name="section164824754712"></a>
+
+1.  编辑Makefile，添加源文件：
+
+    ```
+    include drivers/hdf/khdf/platform/platform.mk
+    
+    obj-y  += $(HDF_PLATFORM_FRAMEWORKS_ROOT)/src/i2c_core.o \
+              $(HDF_PLATFORM_FRAMEWORKS_ROOT)/src/i2c_if.o \
+              ./i2c_adapter.o \
+              ./i2c_sample.o
+    ```
+
+    "./i2c\_sample.o"为本示例中在Makefile中追加的内容。
+
+2.  编译及烧录。
+
+    具体操作请参考[标准系统快速入门编译及烧录章节](../quick-start/quickstart-standard.md)。

+            cam_ = &c;
+        }
+        void OnCreateFailed(const std::string cameraId, int32_t errorCode) override {}
+        void OnReleased(Camera &c) override {}
+    };
+    ```
+
+4.  创建CameraKit，用于创建和获取camera信息。
+
+    ```
+    CameraKit *camKit = CameraKit::GetInstance();
+    list<string> camList = camKit->GetCameraIds();
+    string camId;
+    for (auto &cam : camList) {
+        cout << "camera name:" << cam << endl;
+        const CameraAbility *ability = camKit->GetCameraAbility(cam);
+        /* find camera which fits user's ability */
+        list<CameraPicSize> sizeList = ability->GetSupportedSizes(0);
+        if (find(sizeList.begin(), sizeList.end(), CAM_PIC_1080P) != sizeList.end()) {
+            camId = cam;
+            break;
+        }
+    }
+    ```
+
+5.  创建Camera实例。
+
+    ```
+    EventHandler eventHdlr; // Create a thread to handle callback events
+    SampleCameraStateMng CamStateMng(eventHdlr);
+    
+    camKit->CreateCamera(camId, CamStateMng, eventHdlr);
+    ```
+
+6.  根据[步骤1](#zh-cn_topic_0000001052170554_li378084192111)、[步骤2](#zh-cn_topic_0000001052170554_li8716104682913)、[步骤3](#zh-cn_topic_0000001052170554_li6671035102514)中的回调设计，camera实例创建成功后会进行配置操作，主流程中app需要设计同步机制。
+
+    ```
+    void OnCreated(Camera &c) override
+    {
+        cout << "Sample recv OnCreate camera." << endl;
+        auto config = CameraConfig::CreateCameraConfig();
+        config->SetFrameStateCallback(&fsCb_, &eventHdlr_);
+        c.Configure(*config);
+        cam_ = &c;
+    }
+    
+    void Capture()
+    {
+        if (cam_ == nullptr) {
+            cout << "Camera is not ready." << endl;
+            return;
+        }
+        FrameConfig *fc = new FrameConfig(FRAME_CONFIG_CAPTURE);
+        Surface *surface = Surface::CreateSurface();
+        if (surface == nullptr) {
+            delete fc;
+            return;
+        }
+        surface->SetWidthAndHeight(1920, 1080); /* 1920:width,1080:height */
+        fc->AddSurface(*surface);
+        cam_->TriggerSingleCapture(*fc);
+    }
+    ```

+## 概述<a name="section86753818426"></a>
+
+本文档将介绍如何基于Hi3516DV300开发板完成基于HDF\_Input模型的触摸屏器件驱动开发，从而使开发者快速入门，进行基于的外设驱动开发。
+
+### 硬件资源简介<a name="section123071189431"></a>
+
+Hi3516DV300开发板套件所提供的触摸屏器件IC为GT911，该器件采用标准I2C与主机通信，通过6pin软排线与主板连接。6pin分布以及实物连接图如下图所示：
+
+![](figure/绘图1.png)
+
+### Input模型简介<a name="section53684425430"></a>
+
+Input驱动模型核心部分由设备管理层、公共驱动层、器件驱动层组成。其中：
+
+-   设备管理层：主要为各类输入设备驱动提供input设备的注册、注销接口，同时统一管理input设备列表；
+-   公共驱动层：负责对板级硬件进行初始化、硬件中断处理、向manager注册input设备等；
+-   器件驱动层：通过适配平台驱动预留的差异化接口，实现器件驱动开发量最小化；
+
+此外，Input模型预先实现了数据通道以及设备配置信息解析等函数。
+
+关于Input模型的详细介绍请参考《[Touchscreen开发概述](../driver/drive-peripherals-touch-des.md#section175431838101617)》。
+
+## 环境搭建<a name="section661075474418"></a>
+
+环境准备具体操作请参考[标准系统基础环境搭建](../quick-start/quickstart-standard.md)。
+
+>![](../public_sys-resources/icon-notice.gif) **须知：** 
+>本示例针对OpenHarmony轻量系统、小型系统、标准系统都适用，本文以标准系统为例。其他系统的开发者可参考对应系统的指导文档进行环境搭建。
+
+## TouchScreen器件驱动开发<a name="section15233162984520"></a>
+
+基于Input模型适配一款触摸屏IC需要完成的具体工作见下。
+
+### 配置设备描述信息<a name="section16761205604515"></a>
+
+驱动注册到HDF框架所需要的设备驱动描述信息，如驱动是否加载以及加载次序等。
+
+配置文件路径：./drivers/adapter/khdf/linux/hcs/device\_info/device\_info.hcs
+
+device\_info.hcs中的信息主要提供给HDF框架使用，包含了Input模型各层驱动注册到HDF框架所必需的信息，开发者无特殊场景需求无需改动。各驱动层私有配置信息通过“deviceMatchAttr”字段与input\_config.hcs中的“match\_attr”相关内容进行匹配。
+
+配置文件中与input模块相关的内容如下所示，相关字段的详细含义可以参考《[驱动配置](../driver/drive-hdf-development.md)》：
+
+```
+input :: host {
+            hostName = "input_host";
+            priority = 100;
+            device_input_manager :: device {              // Input管理层设备描述信息
+                device0 :: deviceNode {
+                    policy = 2;                           // 向内核用户态均发布服务
+                    priority = 100;                       // input管理层驱动优先级默认为100
+                    preload = 0;                          // 加载该驱动
+                    permission = 0660;                    // 驱动创建设备节点权限
+                    moduleName = "HDF_INPUT_MANAGER";     // 与驱动入口的moduleName匹配
+                    serviceName = "hdf_input_host";       // HDF框架生成的节点名
+                    deviceMatchAttr = "";                 // manager目前不需要私有配置，因此为空
+                }
+            }
+
+            device_hdf_touch :: device {                  // Input公共驱动层设备描述信息
+                device0 :: deviceNode {
+                    policy = 2;                           // 向内核用户态均发布服务
+                    priority = 120;                       // input公共驱动优先级默认为120
+                    preload = 0;                          // 加载该驱动
+                    permission = 0660;                    // 驱动创建设备节点权限
+                    moduleName = "HDF_TOUCH";             // 与驱动入口的moduleName匹配
+                    serviceName = "hdf_input_event1";     // HDF框架生成的节点名
+                    deviceMatchAttr = "touch_device1";    // 与私有配置信息中的“match_attr”字段保持一致
+                }
+            }
+
+            device_touch_chip :: device {                 // Input器件驱动层信息
+                device0 :: deviceNode {
+                    policy = 0;                           // 向内核用户态均不发布服务
+                    priority = 130;                       // input器件驱动优先级默认为130
+                    preload = 0;                          // 加载该驱动
+                    permission = 0660;                    // 驱动创建设备节点权限
+                    moduleName = "HDF_TOUCH_GT911";       // 与驱动入口的moduleName匹配
+                    serviceName = "hdf_touch_gt911_service";// HDF框架生成的节点名
+                    deviceMatchAttr = "zsj_gt911_5p5";    //与私有配置信息中的“match_attr”字段保持一致
+                }
+            }
+  }
+```
+
+该配置文件中需要重点关注的字段有：
+
+“priority”决定驱动加载顺序；
+
+“preload”决定驱动是否加载；
+
+“moduleName ”需要与驱动注册入口处的“moduleName ”字段保持一致；
+
+“serviceName ”HDF框架依据该字段创建节点名；
+
+“deviceMatchAttr ”需要与私有配置信息中的“match\_attr”字段保持一致。
+
+通过配置设备描述信息，使得HDF框架通过moduleName与注册至驱动入口的代码相匹配，保证了驱动的正常加载，通过priority字段保证了各驱动的加载顺序。
+
+### 配置Touchscreen器件信息<a name="section156331030144617"></a>
+
+器件私有信息包括上下电时序等，平台硬件信息包括器件连接主板的GPIO端口信息等。
+
+配置文件路径：./drivers/adapter/khdf/linux/hcs/input/input\_config.hcs
+
+input\_config.hcs中的信息由驱动代码进行读取解析，主要由公共驱动层的私有配置信息及器件驱动层的私有配置信息组成。文件中的配置包含板级硬件信息及器件私有配置信息，实际业务开发时，可根据具体需求增删及修改对应内容。
+
+```

+示例中“touchConfig”包含了“touch0”，"touch0"包含了“boardConfig”与“chipConfig”；“boardConfig”字段包含了Hi3516DV300板级硬件信息，“chipConfig”包含了触摸屏器件的私有信息，如果需要替换触摸屏器件，重新配置“chipConfig”对应的字段信息即可。同时产品可以配置多款触摸屏，示例中用“touch0”代表了套件中默认的触摸屏的硬件接口以及器件的配置信息，如产品需要配置副屏，可在与“touch0”并列的位置配置“touch1”的信息。

+### 适配器件私有驱动<a name="section17127331595"></a>
+
+Input模型对Input设备开发流程进行了抽象，开发者只需要适配器件驱动层，无需改动管理驱动层以及公共驱动层。
+
+Input模型由三层驱动组成，开发者适配一款全新触摸屏驱动只需要适配器件驱动层即可，重点实现差异化接口，本小节以代码示例的形式展示开发者需要重点完成的工作。
+
+1.  触摸屏器件差异化接口适配
+
+    示例代码路径：./drivers/framework/model/input/driver/touchscreen/touch\_gt911.c
+
+    ```
+    static struct TouchChipOps g_gt911ChipOps = {                                  // 器件IC接口
+        .Init = ChipInit,                                                          // 初始化
+        .Detect = ChipDetect,                                                      // 器件检测
+        .Resume = ChipResume,                                                      // 唤醒
+        .Suspend = ChipSuspend,                                                    // 休眠
+        .DataHandle = ChipDataHandle,                                              // 器件数据读取
+        .UpdateFirmware = UpdateFirmware,                                          // 固件升级
+    };
+    
+    /* 不同触摸屏厂家使用的IC不一样，对应的寄存器操作也不一样，因此器件驱动层代码重点适配差异化接口部分，如下示例代码展示了GT911的数据解析*/
+    
+    static int32_t ChipDataHandle(ChipDevice *device)
+    {
+        ...
+        /*  GT911获取坐标之前需先读取状态寄存器  */
+        reg[0] = (GT_BUF_STATE_ADDR >> ONE_BYTE_OFFSET) & ONE_BYTE_MASK; 
+        reg[1] = GT_BUF_STATE_ADDR & ONE_BYTE_MASK;
+        ret = InputI2cRead(i2cClient, reg, GT_ADDR_LEN, &touchStatus, 1);
+        if (ret < 0 || touchStatus == GT_EVENT_INVALID) {
+            return HDF_FAILURE;
+        }
+        ...
+        /* 根据状态寄存器的值读取数据寄存器数据 */
+        reg[0] = (GT_X_LOW_BYTE_BASE >> ONE_BYTE_OFFSET) & ONE_BYTE_MASK;
+        reg[1] = GT_X_LOW_BYTE_BASE & ONE_BYTE_MASK;
+        pointNum = touchStatus & GT_FINGER_NUM_MASK;
+        if (pointNum == 0 || pointNum > MAX_SUPPORT_POINT) {
+            HDF_LOGE("%s: pointNum is invalid, %u", __func__, pointNum);
+            (void)ChipCleanBuffer(i2cClient);
+            OsalMutexUnlock(&device->driver->mutex);
+            return HDF_FAILURE;
+        }
+        frame->realPointNum = pointNum;
+        frame->definedEvent = TOUCH_DOWN;
+        (void)InputI2cRead(i2cClient, reg, GT_ADDR_LEN, buf, GT_POINT_SIZE * pointNum);
+        /* 对获取的数据进行解析 */
+        ParsePointData(device, frame, buf, pointNum);
+        ...
+    }
+    static void ParsePointData(ChipDevice *device, FrameData *frame, uint8_t *buf, uint8_t pointNum)
+    {
+        ...
+        /* 每个坐标值由两个字节组成，对获取的单字节数据进行拼接得到最终的坐标值 */
+        for (i = 0; i < pointNum; i++) {
+                frame->fingers[i].trackId = buf[GT_POINT_SIZE * i + GT_TRACK_ID];
+                frame->fingers[i].y = (buf[GT_POINT_SIZE * i + GT_X_LOW] & ONE_BYTE_MASK) |
+                                      ((buf[GT_POINT_SIZE * i + GT_X_HIGH] & ONE_BYTE_MASK) << ONE_BYTE_OFFSET);
+                frame->fingers[i].x = (buf[GT_POINT_SIZE * i + GT_Y_LOW] & ONE_BYTE_MASK) |
+                                      ((buf[GT_POINT_SIZE * i + GT_Y_HIGH] & ONE_BYTE_MASK) << ONE_BYTE_OFFSET);
+                /* 对解析出来的坐标值进行打印 */
+                HDF_LOGD("%s: x = %d, y = %d", __func__, frame->fingers[i].x, frame->fingers[i].y);
+         }
+    }
+    ```
+
+2.  器件层驱动初始化及注册驱动至HDF框架
+
+    示例代码路径：./drivers/framework/model/input/driver/touchscreen/touch\_gt911.c
+
+    ```
+    static int32_t HdfGoodixChipInit(struct HdfDeviceObject *device)
+    {
+        ...
+        /* 器件配置结构体内存申请、配置信息解析及挂载 */
+        chipCfg = ChipConfigInstance(device);
+        ...
+        /* 器件实例化 */
+        chipDev = ChipDeviceInstance();
+        ...
+        /* 器件信息挂载及器件私有操作挂载 */
+        chipDev->chipCfg = chipCfg;
+        chipDev->ops = &g_gt911ChipOps;
+        ...
+        /* 注册器件驱动至平台驱动 */
+        RegisterChipDevice(chipDev);
+        ...
+    }
+    struct HdfDriverEntry g_touchGoodixChipEntry = {
+        .moduleVersion = 1,
+        .moduleName = "HDF_TOUCH_GT911",   // 该moduleName与device_info.hcs文件中器件驱动层的moduleName信息相匹配
+        .Init = HdfGoodixChipInit,         // 器件驱动初始化函数
+    };
+    HDF_INIT(g_touchGoodixChipEntry);      // 注册器件驱动至HDF框架
+    ```
+
+    器件私有驱动层主要实现了各器件厂商差异较大的部分，如器件休眠唤醒、数据解析以及固件升级等。
+
+    至此，基于HDF框架及Input模型的触摸屏驱动适配完成。

+
+>![](../public_sys-resources/icon-notice.gif) **须知：** 
+>本章节为Input模型工作流程说明，开发者无需进行开发。
+
+### 私有配置信息解析<a name="section1310113815495"></a>
+
+示例代码路径：./drivers/framework/model/input/driver/input\_config\_parser.c
+
+根据OSAL提供的配置解析函数，可以将hcs文件中各字段含义进行解析，具体请参考input\_config\_parser.c中各函数的实现。如果提供的模板不能满足需求，在hcs文件中添加相应信息后，需要根据添加的字段开发相应的解析函数。
+
+```
+static int32_t ParseAttr(struct DeviceResourceIface *parser, const struct DeviceResourceNode *attrNode, BoardAttrCfg *attr)
+{
+    int32_t ret;
+    ret = parser->GetUint8(attrNode, "inputType", &attr->devType, 0);     // 获取inputType字段信息，保存在BoardAttrCfg结构体中
+    CHECK_PARSER_RET(ret, "GetUint8");
+    ...
+    return HDF_SUCCESS;

+-   [概述](#section14639174516337)
+-   [开发](#section13857170163412)
+-   [验证](#section1949121910344)
+
+## 概述<a name="section14639174516337"></a>
+
+OpenHarmony  WLAN模组基于Hi3861平台提供了丰富的外设操作能力，包含I2C、I2S、ADC、UART、SPI、SDIO、GPIO、PWM、FLASH等。本文介绍如何通过调用OpenHarmony的NDK接口，实现对GPIO控制，达到LED闪烁的效果。其他的IOT外设控制，开发者可根据API指导文档完成，此处不逐一介绍。
+
+## 开发<a name="section13857170163412"></a>
+
+1.  请先完成[《Hi3861快速入门》](../quick-start/quickstart-lite-introduction-hi3861.md#section19352114194115)。
+
+    LED控制参考示例存放于applications/sample/wifi-iot/app/iothardware/led\_example.c文件中。
+
+2.  实现IOT外设控制，首先需要通过查阅原理图明确接线关系。经过查阅，hispark pegasus的LED与芯片的9号管脚相连。
+
+    ```
+    #define LED_TEST_GPIO 9
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >开发板原理图，请开发者联系Hi3861购买渠道客服获取。
+
+3.  使用GPIO前，需要完成GPIO管脚初始化，明确管脚用途，并创建任务，使LED周期性亮灭，达到闪烁的效果。
+
+    ```
+    static void LedExampleEntry(void)
+    {
+        osThreadAttr_t attr;
+    
+        /* 管脚初始化 */
+        IoTGpioInit(LED_TEST_GPIO);
+        /* 配置9号管脚为输出方向 */
+        IoTGpioSetDir(LED_TEST_GPIO, IOT_GPIO_DIR_OUT);
+    
+        attr.name = "LedTask";
+        attr.attr_bits = 0U;
+        attr.cb_mem = NULL;
+        attr.cb_size = 0U;
+        attr.stack_mem = NULL;
+        attr.stack_size = LED_TASK_STACK_SIZE;
+        attr.priority = LED_TASK_PRIO;
+    
+        /* 启动任务 */
+        if (osThreadNew((osThreadFunc_t)LedTask, NULL, &attr) == NULL) {
+            printf("[LedExample] Failed to create LedTask!\n");
+        }
+    }
+    ```
+
+4.  在循环任务中通过周期性亮灭形式实现LED闪烁。
+
+    ```
+    static void *LedTask(const char *arg)
+    {
+        (void)arg;
+        while (1) {
+            switch (g_ledState) {
+                case LED_ON:
+                    IoTGpioSetOutputVal(LED_TEST_GPIO, 1);
+                    usleep(LED_INTERVAL_TIME_US);
+                    break;
+                case LED_OFF:
+                    IoTGpioSetOutputVal(LED_TEST_GPIO, 0);
+                    usleep(LED_INTERVAL_TIME_US);
+                    break;
+                case LED_SPARK:
+                    IoTGpioSetOutputVal(LED_TEST_GPIO, 0);
+                    usleep(LED_INTERVAL_TIME_US);
+                    IoTGpioSetOutputVal(LED_TEST_GPIO, 1);
+                    usleep(LED_INTERVAL_TIME_US);
+                    break;
+                default:
+                    usleep(LED_INTERVAL_TIME_US);
+                    break;
+            }
+        }
+        return NULL;
+    }
+    ```
+
+5.  在代码最下方，使用OpenHarmony启动恢复模块接口SYS\_RUN\(\)启动业务。（SYS\_RUN定义在ohos\_init.h文件中）
+
+    ```
+    SYS_RUN(LedExampleEntry);
+    ```
+
+6.  修改applications/sample/wifi-iot/app/BUILD.gn文件，使led\_example.c参与编译。
+
+    ```
+    import("//build/lite/config/component/lite_component.gni")
+    lite_component("app") {
+        features = [
+            "iothardware:led_example"
+        ]
+    }
+    ```
+
+
+## 验证<a name="section1949121910344"></a>
+
+编译过程请参考《[Hi3861快速入门-源码编译](../quick-start/quickstart-lite-steps-board3861-connection.md#section191121332125319)》，烧录过程请参考《[Hi3861快速入门-镜像烧录](../quick-start/quickstart-lite-steps-board3861-connection.md#section19458165166)》。
+
+完成以上两步后，按下RST键复位模组，可发现LED在周期性闪烁，与预期相符，验证完毕。

+
+OpenHarmony致力于打造一套更加开放完善的IoT生态系统，为此OpenHarmony规划了一组目录，用于将各厂商的SDK集成到OpenHarmony中。本文档基于Hi3861开发板，向平台开发者介绍将SDK集成到OpenHarmony的方法。
+
+## 规划目录结构<a name="section1736472718351"></a>
+
+三方SDK通常由静态库和适配代码构成。SDK的业务逻辑通过硬件模组工具链编译得到静态库libs，每款模组都有其对应的libs。SDK的南向API与OpenHarmony 的API存在使用差异，该差异可通过adapter适配代码屏蔽，不同模组可共用一套adapter。
+
+基于以上特征，在OpenHarmony目录结构中，可以对三方SDK目录做如下划分。
+
+-   适配代码adapter，放置到domains/iot/link/ 目录下，与模组解耦。
+-   业务库libs，放置到device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/ 目录下，与模组绑定。
+
+平台开发者在适配前，务必先依次完成以下步骤，下面以demolink SDK举例，进行介绍。
+
+1.  创建厂商目录，domains/iot/link/demolink/、device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/demolink/ ，用于厂商隔离。
+2.  创建domains/iot/link/demolink/BUILD.gn ，用于构建适配代码。
+3.  创建device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/demolink/libs/ 目录，用于存放业务库libs。
+
+```
+.
+├── domains
+│   └── iot
+│       └── link
+│           ├── demolink
+│           │   └── BUILD.gn
+│           ├── libbuild
+│           │   └── BUILD.gn
+│           └── BUILD.gn
+└── device
+     └── hisilicon
+         └── hispark_pegasus
+             └── sdk_liteos
+                 └── 3rd_sdk
+                     └── demolink
+                         └── libs
+```
+
+## 构建业务libs<a name="section442815485351"></a>
+
+平台SDK业务一般以静态库的形式提供，平台厂商在获取到OpenHarmony代码后，需要根据对应的硬件模组vendor，编译业务libs，并将编译结果放置在device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/demolink/libs/ 目录下。下面介绍业务libs的构建方法。
+
+OpenHarmony已规划用于编译业务libs的目录domains/iot/link/libbuild/ ，该目录中包含domains/iot/link/libbuild/BUILD.gn和domains/iot/link/BUILD.gn文件，目录结构如下。
+
+```
+.
+└── domains
+    └── iot
+        └── link
+            ├── demolink
+            │   └── BUILD.gn
+            ├── libbuild
+            │   └── BUILD.gn
+            └── BUILD.gn
+```
+
+平台开发者在构建libs前，务必先完成如下步骤。
+
+1.  在domains/iot/link/libbuild/ 目录下放置业务源码文件，包括.c和.h文件。
+
+    ```
+    .
+    └── domains
+        └── iot
+            └── link
+                ├── demolink
+                │   ├── demosdk_adapter.c
+                │   ├── demosdk_adapter.h
+                │   └── BUILD.gn
+                ├── libbuild
+                │   ├── demosdk.c
+                │   ├── demosdk.h
+                │   └── BUILD.gn
+                └── BUILD.gn
+    ```
+
+2.  适配domains/iot/link/libbuild/BUILD.gn，在编译完成后还原该文件。
+
+    在BUILD.gn中，sources为需要参与构建的源文件，include\_dirs为依赖的头文件路径，构建的目标结果是生成静态库libdemosdk.a。
+
+    ```
+    static_library("demosdk") {
+        sources = [
+            "demosdk.c"
+        ]
+        include_dirs = [
+            "//domains/iot/link/libbuild",
+            "//domains/iot/link/demolink"
+        ]
+    }
+    ```
+
+3.  适配domains/iot/link/BUILD.gn，在编译完成后还原该文件。
+
+    此BUILD.gn文件用于指定构建条目，需要在features中填入所有需参与编译的静态库条目，使domains/iot/link/libbuild/BUILD.gn参与到构建中来。
+
+    ```
+    import("//build/lite/config/subsystem/lite_subsystem.gni")
+    import("//build/lite/config/component/lite_component.gni")
+    lite_subsystem("iot") {
+        subsystem_components = [
+            ":link"
+        ]
+    }
+    lite_component("link") {
+        features = [
+            "libbuild:demosdk"
+        ]
+    }
+    ```
+
+
+完成以上3点后，需在代码根目录下执行命令“hb build -T //domains/iot/link:iot”，等待执行完成，检查out/hispark\_pegasus/wifiiot\_hispark\_pegasus/libs/目录下是否生成了目标库文件。
+
+![](figure/zh-cn_image_0000001078563230.png)
+
+将库文件拷贝到device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/demolink/libs/ 目录下，并将domains/iot/link/libbuild/ 目录中的.c和.h文件清除。
+
+## 编写适配代码<a name="section3984721113613"></a>
+
+## 代码编写<a name="section830417531286"></a>
+
+平台SDK中使用的API通常与OpenHarmony API存在差异，无法直接使用，需要一层适配代码adapter进行中间转换。本节以domains/iot/link/demolink/demosdk\_adapter.c中的任务创建接口DemoSdkCreateTask举例，向开发者演示如何在OpenHarmony上编写适配代码。
+
+1.  查看待适配接口DemoSdkCreateTask的描述、参数、返回值。
+
+    ```
+    struct TaskPara {
+        char *name;
+        void *(*func)(char* arg);
+        void *arg;
+        unsigned char prio;
+        unsigned int size;
+    };
+    
+    /*
+     * IoT OS 创建线程接口
+     * 返回值: 返回0 成功, 其他 失败
+     */
+    int DemoSdkCreateTask(unsigned int *handle, const struct TaskPara *para);
+    ```
+
+2.  查看OpenHarmony API接口文档，选取一个功能类似的接口，并比对参数及用法上的差异。例如本文选取osThreadNew ，通过和DemoSdkCreateTask接口比对，可以发现两接口依赖的参数基本一致，只是参数所归属的结构体不同。
+
+    ```
+    typedef struct {
+        const char                   *name;   ///< name of the thread
+        uint32_t                 attr_bits;   ///< attribute bits
+        void                      *cb_mem;    ///< memory for control block
+        uint32_t                   cb_size;   ///< size of provided memory for control block
+        void                   *stack_mem;    ///< memory for stack
+        uint32_t                stack_size;   ///< size of stack
+        osPriority_t              priority;   ///< initial thread priority (default: osPriorityNormal)
+        TZ_ModuleId_t            tz_module;   ///< TrustZone module identifier
+        uint32_t                  reserved;   ///< reserved (must be 0)
+    } osThreadAttr_t;
+    
+    /// Create a thread and add it to Active Threads.
+    /// \param[in]     func          thread function.
+    /// \param[in]     argument      pointer that is passed to the thread function as start argument.
+    /// \param[in]     attr          thread attributes; NULL: default values.
+    /// \return thread ID for reference by other functions or NULL in case of error.
+    osThreadId_t osThreadNew (osThreadFunc_t func, void *argument, const osThreadAttr_t *attr);
+    ```
+
+3.  完成代码差异转换。
+
+    ```
+    int DemoSdkCreateTask(unsigned int *handle, const struct TaskPara *para)
+    {
+        osThreadAttr_t attr = {0};
+        osThreadId_t threadId;
+        if (handle == 0 || para == 0) {
+            return DEMOSDK_ERR;
+        }
+        if (para->func == 0) {
+            return DEMOSDK_ERR;
+        }
+        if (para->name == 0) {
+            return DEMOSDK_ERR;
+        }
+        attr.name = para->name;
+        attr.priority = para->prio;
+        attr.stack_size = para->size;
+        threadId = osThreadNew((osThreadFunc_t)para->func, para->arg, &attr);
+        if (threadId == 0) {
+            printf("osThreadNew fail\n");
+            return DEMOSDK_ERR;
+        }
+        *(unsigned int *)handle = (unsigned int)threadId;
+        return DEMOSDK_OK;
+    }
+    ```
+
+
+## 脚本编写<a name="section13500201173710"></a>
+
+开发者在完成代码适配后，还需要在adapter同级目录下新建BUILD.gn文件。该文件可在整包构建时，将适配代码编译成静态库，并链接到bin包中去。在domains/iot/link/demolink/BUILD.gn中，sources中为需要参与构建的源文件，include\_dirs中为依赖的头文件路径，构建目标结果是生产静态库libdemolinkadapter.a。
+
+```
+import("//build/lite/config/component/lite_component.gni")
+static_library("demolinkadapter") {
+    sources = [
+        "demosdk_adapter.c"
+    ]
+    include_dirs = [
+        "//kernel/liteos-m/kal/cmsis",
+        "//domains/iot/link/demolink"
+    ]
+}
+```
+
+修改domains/iot/link/BUILD.gn文件，使domain/iot/hilink/BUILD.gn参与到构建系统中。
+
+```
+import("//build/lite/config/subsystem/lite_subsystem.gni")
+import("//build/lite/config/component/lite_component.gni")
+lite_subsystem("iot") {
+    subsystem_components = [
+        ":link"
+    ]
+}
+lite_component("link") {
+    features = [
+        "demolink:demolinkadapter"
+    ]
+}

+## 编写业务代码<a name="section8754114803918"></a>
+
+业务libs库和适配代码准备就绪后，还需要编写业务入口函数，调起三方SDK的业务入口。
+
+下面以demolink举例，介绍如何在applications/sample/wifi-iot/app/路径下编写代码，调起demosdk的入口函数。
+
+1.  目录创建
+
+    开发者编写业务时，务必先在applications/sample/wifi-iot/app/ 路径下新建一个目录（或一套目录结构），用于存放业务源码文件。
+
+    例如：在app下新增业务目录demolink，并在其中创建业务入口代码helloworld.c和编译构建文件BUILD.gn，如下。
+
+    ```
+    .
+    └── applications
+        └── sample
+            └── wifi-iot
+                └── app
+                    │── demolink
+                    │    │── helloworld.c
+                    │    └── BUILD.gn
+                    └── BUILD.gn
+    ```
+
+2.  编写业务代码。
+
+    在helloworld.c文件中编写业务入口函数DemoSdkMain，并调起demolink的业务DemoSdkEntry，最后通过SYS\_RUN\(\)调用入口函数完成业务启动。
+
+    ```
+    #include "hos_init.h"
+    #include "demosdk.h"
+    
+    void DemoSdkMain(void)
+    {
+        DemoSdkEntry();
+    }
+    
+    SYS_RUN(DemoSdkMain);
+    ```
+
+3.  编写构建脚本
+
+    新增applications/sample/wifi-iot/app/demolink/BUILD.gn文件，指定源码和头文件路径，编译输出静态库文件libexample\_demolink.a。
+
+    ```
+    static_library("example_demolink") {
+        sources = [
+            "helloworld.c"
+        ]
+        include_dirs = [
+            "//utils/native/lite/include",
+            "//domains/iot/link/libbuild"
+        ]
+    }
+    ```
+
+    修改applications/sample/wifi-iot/app/BUILD.gn，使demolink参与编译。
+
+    ```
+    import("//build/lite/config/component/lite_component.gni")
+    lite_component("app") {
+        features = [
+            "demolink:example_demolink"
+        ]
+    }
+    ```
+
+
+## 运行<a name="section7737749184012"></a>
+
+在代码根目录下，执行命令“hb build”编译输出版本包。最后启动运行，运行结果如图所示，与demolink预期相符。
+
+```
+ready to OS start
+sdk ver:Hi3861V100R001C00SPC024 2020-08-05 16:30:00
+formatting spiffs...
+FileSystem mount ok.
+wifi init success!
+it is demosdk entry.
+it is demo biz: hello world.
+it is demo biz: hello world.
+```
+
+## 结束<a name="section153301392411"></a>
+
+至此，三方SDK集成已介绍完毕。

-# 具体调用逻辑串联函数<a name="ZH-CN_TOPIC_0000001158241891"></a>
-
-Input模型管理层驱动init函数初始化了设备管理链表，公共驱动层初始化函数完成了相关结构体的内存申请。器件驱动相关信息通过RegisterChipDevice函数对公共驱动层相关结构体进行信息填充，同时完成了相关硬件信息的初始化（如中断注册等），绑定设备与驱动组成inputDev通过RegisterInputDevice函数向驱动管理层进行注册，在RegisterInputDevice函数中主要实现了将inputDev向设备管理链表的添加等功能。如下所示为两个函数的实现部分：
-
-```
-//函数具体实现代码位置 ：./drivers/framework/model/input/driver/hdf_touch.c
-int32_t RegisterChipDevice(ChipDevice *chipDev)
-{
-    ...
-    /* 绑定设备与驱动，从而通过InputDeviceInstance函数创建inputDev */
-    DeviceBindDriver(chipDev);
-    ...
-    /* 主要包含器件中断注册及中断处理函数,中断处理函数中有数据上报用户态的数据通道 */
-    ChipDriverInit(chipDev);
-    ...
-    /* 申请内存实例化InputDev */
-    inputDev = InputDeviceInstance(chipDev);
-    ...
-    /* 将InputDev设备注册至input驱动管理层 */
-    RegisterInputDevice(inputDev);
-    ...
-}
-
-//函数具体实现代码位置 ：./drivers/framework/model/input/driver/hdf_input_device_manager.c
-int32_t RegisterInputDevice(InputDevice *inputDev)
-{
-    ...
-    /* 申请ID，该ID对于不同input设备唯一 */
-    ret = AllocDeviceID(inputDev);
-    ...
-    /* 该函数包含了对hid类设备的特殊处理，对于触摸屏驱动，该函数无实质操作； */
-    CreateDeviceNode(inputDev);
-    /* 内核态数据传送至用户态需使用IOService能力，需要申请buffer */
-    AllocPackageBuffer(inputDev);
-    /* 将input设备添加进设备全局管理链表 */
-    AddInputDevice(inputDev);
-    ...

-## hdc\_std连接不到设备<a name="section1221016541119"></a>
-
--   **现象描述**
-
-    执行 "hdc\_std list targets"命令后结果为：\[Empty\]
-
--   **可能原因和解决方法**
-    1.  设备没有被识别：
-
-        在设备管理器中查看是否有hdc设备，在通用串行总线设备中会有“HDC Device”信息。如果没有，hdc无法连接。此时需要插拔设备，或者烧写最新的镜像。
-
-    2.  hdc\_std工作异常：
-
-        可以执行"hdc kill"或者"hdc start -r"杀掉hdc服务或者重启hdc服务，然后再执行hdc list targets查看是否已经可以获取设备信息。
-
-        如果一直获取不到设备信息，请在任务管理器中查询是否有adb进程，该进程可能会对hdc产生干扰，可以将其杀掉后重复执行上面的步骤。
-
-    3.  hdc\_std与设备不匹配：
-
-        如果设备烧写的是最新镜像，hdc\_std也需要使用最新版本。由于hdc\_std会持续更新，请从开源仓developtools\_hdc\_standard中获取，具体位置在该开源仓的prebuilt目录。

-## hdc\_std运行不了<a name="section219185710311"></a>
-
--   **现象描述**
-
-    点击hdc\_std.exe文件无法运行。
-
--   **可能原因和解决方法**
-
-    hdc\_std.exe不需要安装，直接放到磁盘上就能使用，也可以添加到环境变量中。通过打开cmd执行hdc\_std命令直接使用。

-## 实例化驱动入口<a name="section6586911816"></a>
-
-驱动入口必须为HdfDriverEntry（在hdf\_device\_desc.h中定义）类型的全局变量，且moduleName要和device\_info.hcs中保持一致。在加载驱动时HDF框架会先调用Bind函数，再调用Init函数加载该驱动，当Init调用异常时，HDF框架会调用Release释放驱动资源并退出。
-
-I2C驱动中没有实现Bind方法，因为I2C控制器由manager管理，而在manager中已经实现了Bind方法，因此I2C驱动中无需再绑定服务。
-
-实例化驱动入口的示例代码如下：

-## 设置相关参数<a name="section114323217503"></a>
-
-1.  添加设备服务节点（必选）。
-
-    编辑device\_info.hcs，在device\_i2c :: device下添加驱动设备服务节点，示例如下：
-
-    ```
-     root {
-        device_info {
-            match_attr = "hdf_manager";
-                device_i2c :: device {                        // i2c设备节点
-    		device2 :: deviceNode {                   // i2c驱动的DeviceNode节点
-                        policy = 0;                           // policy字段是驱动服务发布的策略
-                        priority = 55;                        // 驱动启动优先级
-                        permission = 0644;                    // 驱动创建设备节点权限
-                        moduleName = "demo_i2c_driver";       // 驱动名称，该字段的值必须和驱动入口结构的moduleName值一致
-                        serviceName = "DEMO_I2C_DRIVER";      // 驱动对外发布服务的名称，必须唯一
-                        deviceMatchAttr = "demo_i2c_config";  // 驱动私有数据匹配的关键字，必须和驱动私有数据配置表中的
-                                                              // match_attr值相等
-                    }
-                }
-        }
-    }
-    
-    ```
-
-    >![](public_sys-resources/icon-notice.gif) **须知：** 
-    >配置文件中的priority（取值范围为整数0到200）是用来表示host和驱动的优先级，不同的host内的驱动，host的priority值越小，驱动加载优先级越高；同一个host内驱动的priority值越小，加载优先级越高，驱动的priority值相同则不保证加载顺序。
-
-2.  添加配置参数（可选）。
-
-    有时驱动可能会需要私有配置信息，以确保寄存器的配置可以满足不同产品的需求。如需要私有配置信息，则可以添加一个驱动的配置文件，用来存放一些驱动的默认配置信息，HDF框架在加载驱动的时候，会将对应的配置信息获取并保存在HdfDeviceObject 中的property里面，通过Bind和Init（参考[驱动开发](../driver/驱动开发.md)）传递给驱动。驱动开发者可新建配置文件，并在板级驱动hdf.hcs中引用新建的配置文件，本例中直接在原有的配置文件i2c\_config.hcs内添加配置参数。
-
-    本例中编辑i2c\_config.hcs，添加配置参数：
-
-    ```
-    root {
-        platform {
-                i2c_config_demo {                
-                match_attr = "demo_i2c_config";        // 该字段的值必须和device_info.hcs中的deviceMatchAttr值一致
-    
-                template i2c_controller {              // 参数模板
-                    bus = 0;
-                    reg_pbase = 0x120b0000;
-                    reg_size = 0xd1;
-                }
-    
-                controller_demo_0 :: i2c_controller {  // 两个I2C示例控制器
-                    bus = 8;
-                }
-                controller_demo_1 :: i2c_controller {
-                    bus = 9;
-                }
-            }
-        }
-    }
-    ```
-
-    match\_attr字段必须与device\_info.hcs中的deviceMatch\_Attr保持一致，在此文件中配置驱动需要的参数，通过match\_attr可匹配至对应的驱动，该驱动即可在Bind或Init中调用DeviceResourceGetIfaceInstance\(\)函数获取这些配置参数。
-
-    若配置文件为新文件，则需要在板级配置入口文件hdf.hcs中引用该配置文件，例如：
-
-    ```
-    #include "device_info/device_info.hcs"
-    #include "i2c/i2c_config.hcs"
-    ```
-
-    由于本例中在原有的i2c\_config.hcs内添加配置参数，没有新建配置文件，因此无需再将i2c\_config.hcs添加至板级配置入口文件中。
-
-3.  驱动从HCS获取配置参数。
-
-    在本例中，驱动需要通过HCS获取寄存器物理基地址、寄存器大小、总线号等参数，从而对控制器进行正确配置。
-
-    ```
-    /* 从HCS获取配置参数 */
-    static int32_t SampleI2cReadDrs(struct SampleI2cCntlr *sampleCntlr, const struct DeviceResourceNode *node)
-    {
-        int32_t ret;
-        struct DeviceResourceIface *drsOps = NULL;
-    
-        drsOps = DeviceResourceGetIfaceInstance(HDF_CONFIG_SOURCE);
-        if (drsOps == NULL || drsOps->GetUint32 == NULL) {                         // 确保GetUint32方法可用
-            HDF_LOGE("%s: invalid drs ops fail!", __func__);
-            return HDF_FAILURE;
-        }
-    
-        ret = drsOps->GetUint32(node, "reg_pbase", &sampleCntlr->regBasePhy, 0);   // 从HCS读取物理基地址reg_pbase
-        if (ret != HDF_SUCCESS) {
-            HDF_LOGE("%s: read regBase fail!", __func__);
-            return ret;
-        }
-    
-        ret = drsOps->GetUint16(node, "reg_size", &sampleCntlr->regSize, 0);       // 从HCS读取寄存器大小reg_size
-        if (ret != HDF_SUCCESS) {
-            HDF_LOGE("%s: read regsize fail!", __func__);
-            return ret;
-        }
-    
-        ret = drsOps->GetUint16(node, "bus", (uint16_t *)&sampleCntlr->bus, 0);    // 从HCS读取总线号bus
-        if (ret != HDF_SUCCESS) {
-            HDF_LOGE("%s: read bus fail!", __func__);
-            return ret;
-        }
-    
-        return HDF_SUCCESS;
-    }
-    ```
-
-
-## 添加控制器<a name="section115187812516"></a>
-
-1.  定义结构体，实现钩子函数并赋值至函数指针。
-
-    I2cMethod结构体在i2c\_core.h中定义，其中通过函数指针的方式定义了I2C需要实现的方法，transfer方法为用于传输的钩子函数，在驱动中需要做具体实现并对函数指针赋值。
-
-    示例代码如下：
-
-    ```
-    /* 自定义设备结构体，继承父类I2cCntlr */
-    struct SampleI2cCntlr {
-        struct I2cCntlr cntlr;
-        OsalSpinlock spin;
-        volatile unsigned char  *regBase;
-        uint16_t regSize;
-        int16_t bus;
-        uint32_t regBasePhy;
-    };
-    
-    /* 消息结构体，继承父类I2cMsg */
-    struct SampleTransferData {
-        struct I2cMsg *msgs;
-        int16_t index;
-        int16_t count;
-    };
-    /* 钩子函数实现 */
-    static int32_t SampleI2cTransfer(struct I2cCntlr *cntlr, struct I2cMsg *msgs, int16_t count)
-    {
-        int32_t ret = HDF_SUCCESS;
-        struct SampleI2cCntlr *sampleCntlr = NULL;
-        struct SampleTransferData td;
-    
-        if (cntlr == NULL || cntlr->priv == NULL) {
-            HDF_LOGE("SampleI2cTransfer: cntlr lor sampleCntlr is null!");
-            return HDF_ERR_INVALID_OBJECT;
-        }
-        sampleCntlr = (struct SampleI2cCntlr *)cntlr;
-    
-        if (msgs == NULL || count <= 0) {
-            HDF_LOGE("SampleI2cTransfer: err parms! count:%d", count);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        td.msgs = msgs;
-        td.count = count;
-        td.index = 0;
-    
-        HDF_LOGE("Successfully transmitted!");  // 表示此处传输成功
-          
-        td.index = count;                       // 经过处理，最后实际发送msg个数等于count，返回已发送个数，此句代替已省略的处理过程
-        return (td.index > 0) ? td.index : ret;
-    }
-    /* 钩子函数赋值 */
-    static struct I2cMethod g_method = {
-        .transfer = SampleI2cTransfer,
-    };
-    ```
-
-2.  编写驱动初始化函数。
-
-    本例中使用SampleI2cInit作为驱动初始化函数的函数名（函数名称可由驱动开发者确定），该函数需要在驱动入口结构体中赋值给Init，以供HDF驱动框架调用从而达到初始化驱动的目的。该函数中需要对从HCS获取的配置参数进行解析，并按照这些参数创建控制器。示例如下：
-
-    ```
-    /* 解析参数，申请内存并创建控制器 */
-    static int32_t SampleI2cParseAndInit(struct HdfDeviceObject *device, const struct DeviceResourceNode *node)
-    {
-        int32_t ret;
-        struct SampleI2cCntlr *sampleCntlr = NULL;
-        (void)device;
-    
-        sampleCntlr = (struct SampleI2cCntlr *)OsalMemCalloc(sizeof(*sampleCntlr));
-        if (sampleCntlr == NULL) {
-            HDF_LOGE("%s: malloc sampleCntlr fail!", __func__);
-            return HDF_ERR_MALLOC_FAIL;
-        }
-    
-        ret = SampleI2cReadDrs(sampleCntlr, node);              // 从HCS获取配置参数
-        if (ret != HDF_SUCCESS) {
-            HDF_LOGE("%s: read drs fail! ret:%d", __func__, ret);
-            goto __ERR__;
-        }
-    
-        sampleCntlr->regBase = OsalIoRemap(sampleCntlr->regBasePhy, sampleCntlr->regSize);
-        if (sampleCntlr->regBase == NULL) {
-            HDF_LOGE("%s: ioremap regBase fail!", __func__);
-            ret = HDF_ERR_IO;
-            goto __ERR__;
-        }
-    
-        HDF_LOGE("The controller has been initialized!");       // 表示此处省略的控制器初始化操作已经成功
-    
-        sampleCntlr->cntlr.priv = (void *)node;
-        sampleCntlr->cntlr.busId = sampleCntlr->bus;
-        sampleCntlr->cntlr.ops = &g_method;
-        (void)OsalSpinInit(&sampleCntlr->spin);                 // 初始化自旋锁
-        ret = I2cCntlrAdd(&sampleCntlr->cntlr);                 // 向核心层添加控制器
-        if (ret != HDF_SUCCESS) {
-            HDF_LOGE("%s: add i2c controller fail:%d!", __func__, ret);
-            goto __ERR__;
-        }
-    
-        return HDF_SUCCESS;
-    __ERR__:                                                    // 错误处理
-        if (sampleCntlr != NULL) {
-            if (sampleCntlr->regBase != NULL) {
-                OsalIoUnmap((void *)sampleCntlr->regBase);      // 取消地址映射
-                sampleCntlr->regBase = NULL;
-            }
-            OsalMemFree(sampleCntlr);                           // 释放内存
-            sampleCntlr = NULL;
-        }
-        return ret;
-    }
-    /* 驱动入口初始化函数 */
-    static int32_t SampleI2cInit(struct HdfDeviceObject *device)
-    {
-        int32_t ret;
-        const struct DeviceResourceNode *childNode = NULL;
-    
-        HDF_LOGE("%s: Enter", __func__);
-        if (device == NULL || device->property == NULL) {
-            HDF_LOGE("%s: device or property is NULL", __func__);
-            return HDF_ERR_INVALID_OBJECT;
-        }
-    
-        ret = HDF_SUCCESS;
-        DEV_RES_NODE_FOR_EACH_CHILD_NODE(device->property, childNode) {
-            ret = SampleI2cParseAndInit(device, childNode);    // 调用解析参数和创建控制器的函数
-            if (ret != HDF_SUCCESS) {
-                break;
-            }
-        }
-        return ret;
-    }
-    ```
-
-3.  编写驱动释放函数。
-
-    本例中使用SampleI2cRelease作为驱动释放函数的函数名（函数名称可由驱动开发者确定），该函数需要在驱动入口结构体中赋值给Release，当HDF框架调用Init函数初始化驱动失败时，将调用Release释放驱动资源。该函数中需包含释放内存和删除控制器等操作。示例如下：
-
-    ```
-    /* 删除控制器函数 */
-    static void SampleI2cRemoveByNode(const struct DeviceResourceNode *node)
-    {
-        int32_t ret;
-        int16_t bus;
-        struct I2cCntlr *cntlr = NULL;
-        struct SampleI2cCntlr *sampleCntlr = NULL;
-        struct DeviceResourceIface *drsOps = NULL;
-    
-        drsOps = DeviceResourceGetIfaceInstance(HDF_CONFIG_SOURCE);
-        if (drsOps == NULL || drsOps->GetUint32 == NULL) {
-            HDF_LOGE("%s: invalid drs ops fail!", __func__);
-            return;
-        }
-    
-        ret = drsOps->GetUint16(node, "bus", (uint16_t *)&bus, 0); // 从HCS获取I2C总线号
-        if (ret != HDF_SUCCESS) {
-            HDF_LOGE("%s: read bus fail!", __func__);
-            return;
-        }
-    
-        cntlr = I2cCntlrGet(bus);
-        if (cntlr != NULL && cntlr->priv == node) {                // 根据I2C总线号删除控制器
-            I2cCntlrPut(cntlr);
-            I2cCntlrRemove(cntlr);
-            sampleCntlr = (struct SampleI2cCntlr *)cntlr;
-            OsalIoUnmap((void *)sampleCntlr->regBase);
-            OsalMemFree(sampleCntlr);
-        }
-        return;
-    }
-    /* 释放资源 */
-    static void SampleI2cRelease(struct HdfDeviceObject *device)
-    {
-        const struct DeviceResourceNode *childNode = NULL;
-    
-        HDF_LOGI("%s: enter", __func__);
-    
-        if (device == NULL || device->property == NULL) {
-            HDF_LOGE("%s: device or property is NULL", __func__);
-            return;
-        }
-    
-        DEV_RES_NODE_FOR_EACH_CHILD_NODE(device->property, childNode) {
-            SampleI2cRemoveByNode(childNode);                       // 调用删除控制器函数
-        }
-    }
-    ```

-1.  请先完成[《Hi3861快速入门》](../quick-start/Hi3861开发板介绍.md)。
-
-    LED控制参考示例存放于applications/sample/wifi-iot/app/iothardware/led\_example.c文件中。
-
-2.  实现IOT外设控制，首先需要通过查阅原理图明确接线关系。经过查阅，hispark pegasus的LED与芯片的9号管脚相连。
-
-    ```
-    #define LED_TEST_GPIO 9
-    ```
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >开发板原理图，请开发者联系Hi3861购买渠道客服获取。
-
-3.  使用GPIO前，需要完成GPIO管脚初始化，明确管脚用途，并创建任务，使LED周期性亮灭，达到闪烁的效果。
-
-    ```
-    static void LedExampleEntry(void)
-    {
-        osThreadAttr_t attr;
-    
-        /* 管脚初始化 */
-        IoTGpioInit(LED_TEST_GPIO);
-        /* 配置9号管脚为输出方向 */
-        IoTGpioSetDir(LED_TEST_GPIO, IOT_GPIO_DIR_OUT);
-    
-        attr.name = "LedTask";
-        attr.attr_bits = 0U;
-        attr.cb_mem = NULL;
-        attr.cb_size = 0U;
-        attr.stack_mem = NULL;
-        attr.stack_size = LED_TASK_STACK_SIZE;
-        attr.priority = LED_TASK_PRIO;
-    
-        /* 启动任务 */
-        if (osThreadNew((osThreadFunc_t)LedTask, NULL, &attr) == NULL) {
-            printf("[LedExample] Falied to create LedTask!\n");
-        }
-    }
-    ```
-
-4.  在循环任务中通过周期性亮灭形式实现LED闪烁。
-
-    ```
-    static void *LedTask(const char *arg)
-    {
-        (void)arg;
-        while (1) {
-            switch (g_ledState) {
-                case LED_ON:
-                    IoTGpioSetOutputVal(LED_TEST_GPIO, 1);
-                    usleep(LED_INTERVAL_TIME_US);
-                    break;
-                case LED_OFF:
-                    IoTGpioSetOutputVal(LED_TEST_GPIO, 0);
-                    usleep(LED_INTERVAL_TIME_US);
-                    break;
-                case LED_SPARK:
-                    IoTGpioSetOutputVal(LED_TEST_GPIO, 0);
-                    usleep(LED_INTERVAL_TIME_US);
-                    IoTGpioSetOutputVal(LED_TEST_GPIO, 1);
-                    usleep(LED_INTERVAL_TIME_US);
-                    break;
-                default:
-                    usleep(LED_INTERVAL_TIME_US);
-                    break;
-            }
-        }
-        return NULL;
-    }
-    ```
-
-5.  在代码最下方，使用OpenHarmony启动恢复模块接口SYS\_RUN\(\)启动业务。（SYS\_RUN定义在ohos\_init.h文件中）
-
-    ```
-    SYS_RUN(LedExampleEntry);
-    ```
-
-6.  修改applications/sample/wifi-iot/app/BUILD.gn文件，使led\_example.c参与编译。
-
-    ```
-    import("//build/lite/config/component/lite_component.gni")
-    lite_component("app") {
-        features = [
-            "iothardware:led_example"
-        ]
-    }
-    ```

-应用的功能是通过表盘和数字显示实时时间。
-
-从第一章节中的[显示效果图](概述-7.md#fig7763172132019)分析可知，页面由两个部分组成：
-
--   表盘栏：主要展示一个动态的钟表，且钟表指针能准确转动。
--   数字时间栏：主要以数字形式显示当前时间。
-
-综上，我们可搭建一个纵向两行排列的弹性页面布局来实现界面的功能。具体开发步骤如下：
-
-1.  在hml文件中添加一个根节点div，注意每个hml文件中有且只能有一个根节点，代码如下：
-
-    ```
-    <div class="container">
-    </div>
-    ```
-
-    class="container"表示组件使用的样式，container是index.css文件中的一个样式类，代码如下：
-
-    ```
-    .container {     
-        flex-direction: column;
-        justify-content: center;
-        align-items: center;
-        width: 100%;
-        height: 100%;
-    }
-    ```
-
-    在这个样式类中，我们分别设置了根组件div的高度和宽度（注意在应用的开发过程中，除部分组件（text）外必须显式指定组件的高度和宽度，否则可能无法显示）、并将flex-direction属性设置为column，该属性表示div的子组件是垂直方向从上到下排列；这样就可以实现本节开头所说的纵向两行排列的弹性页面布局。
-
-2.  实现时钟转动，需要使用“stack”组件。“stack”组件的功能是堆叠容器，子组件按照顺序依次入栈，后一个子组件覆盖前一个子组件。
-
-    在根组件下添加一个stack容器，代码片段如下：
-
-    ```
-    <div class="container">    
-        <stack class="stack">
-            <image src="/common/clock_bg.png" class="clock-bg"></image> <!--设置表盘图片-->
-            <image src="/common/hour_hand.png" class="clock-hand"
-                   style="transform : rotate({{ hour * 30 + minute / 2 }}deg);"></image> <!--设置时钟图片，(hour * 30)一小时旋转30度，(minute / 2)时钟每分钟旋转的角度-->
-            <image src="/common/minute_hand.png" class="clock-hand"
-                   style="transform : rotate({{ minute * 6 + second / 10 }}deg);"></image> <!--设置分钟图片，(minute * 6)一分钟旋转6度，(second / 10)分钟每秒钟旋转的角度-->
-            <image src="/common/second_hand.png" class="clock-hand"
-                   style="transform : rotate({{ second * 6 }}deg);"></image> <!--设置秒钟图片，(second * 6)一秒旋转6度-->
-       </stack>
-    </div>
-    ```
-
-    style="transform : rotate\(\{\{ second \* 6 \}\}deg\) 这类代码用来设置组件的旋转事件。其中transform是设置动画平移/旋转/缩放的属性，rotate是旋转动画属性，支持设置x轴和y轴两个维度的选中参数。
-
-    在css文件中设置"stack"组件样式的高度、宽度、位置等属性，代码如下：
-
-    ```
-    .stack {
-        flex-direction: column;
-        justify-content: center;
-        align-items: center;
-        width: 100%;
-        height: 50%;
-    }
-    ```
-
-    在css文件中设置"clock-bg"组件样式的高度、宽度等属性，代码如下：
-
-    ```
-    .clock-bg {
-        width: 80%;
-        height: 80%;
-        object-fit: scale-down;
-    }
-    ```
-
-    在css文件中设置"clock-hand"组件为时针、分针和秒针的高度、宽度等属性，代码如下：
-
-    ```
-    .clock-hand {
-        width: 25%;
-        height: 65%;
-        object-fit: contain;
-    }
-    ```
-
-    index.js中会有一个定时器实时刷新时分秒变量，从而触发时间界面自动更新。对应的js代码如下：
-
-    ```
-    export default {
-        timer: undefined,
-        //定义参数
-        data: {
-          hour: 0,   //定义小时
-          minute: 0, //定义分钟
-          second: 0  //定义秒
-        },
-        onInit () {
-            this.updateTime();
-            this.timer = setInterval(this.updateTime, 1000)//设置1s的定时器
-        },  
-        updateTime: function () {       
-            var nowTime = new Date()    
-            this.hour = nowTime.getHours()    
-            this.minute = nowTime.getMinutes()   
-            this.second = nowTime.getSeconds()    
-            if (this.hour < 10) {        
-                this.hour = '0' + this.hour    
-            }  
-            if (this.minute < 10) {       
-                this.minute = '0' + this.minute   
-            }    
-            if (this.second < 10) {      
-                this.second = '0' + this.second   
-            }
-        },
-    }
-    ```
-
-3.  显示数字时间，在钟表下面以数字形式显示当前时间。在根布局内末尾加上text组件，页面结构如下：
-
-    ```
-    <text class="digit-clock"> {{ hour }}:{{ minute }}:{{ second }}</text>
-    ```
-
-    class="digit-clock"设置了组件的高度和宽度以及字体大小，其代码如下：
-
-    ```
-    .digit-clock {    
-        font-size: 58px;   
-        width: 100%;
-        margin-top: 0px;
-        text-align: center;
-    }
-    ```
-
-4.  所有组件设置样式、动画效果和数据动态绑定，完整代码如下所示：
-
-    -   **index.hml文件**
-
-    ```
-    <div class="container">
-        <stack class="stack">
-            <image src="/common/clock_bg.png" class="clock-bg"></image>
-            <image src="/common/hour_hand.png" class="clock-hand"
-                   style="transform : rotate({{ hour * 30 + minute / 2 }}deg);"></image>
-            <image src="/common/minute_hand.png" class="clock-hand"
-                   style="transform : rotate({{ minute * 6 + second / 10 }}deg);"></image>
-            <image src="/common/second_hand.png" class="clock-hand"
-                   style="transform : rotate({{ second * 6 }}deg);"></image>
-        </stack>
-        <text class="digit-clock">{{ hour }}:{{ minute }}:{{ second }}</text>
-    </div>
-    ```
-
-    -   **index.css文件**
-
-    ```
-    .container {
-        flex-direction: column;
-        justify-content: center;
-        align-items: center;
-        width: 100%;
-        height: 100%;
-    }
-    
-    .stack {
-        flex-direction: column;
-        justify-content: center;
-        align-items: center;
-        width: 100%;
-        height: 50%;
-    }
-    
-    .digit-clock {
-        font-size: 58px;
-        width: 100%;
-        margin-top: 0px;
-        text-align: center;
-    }
-    
-    .clock-bg {
-        width: 80%;
-        height: 80%;
-        object-fit: scale-down;
-    }
-    
-    .clock-hand {
-        width: 25%;
-        height: 65%;
-        object-fit: contain;
-    }
-    ```
-
-    -   **index.js:**
-
-    js文件主要用于实现App应用的逻辑交互。在本页面js文件中，需要实现如下功能：定时获取系统时间。
-
-    ```
-    export default {
-        timer: undefined,
-        data: {
-            hour: 0,
-            minute: 0,
-            second: 0
-        },
-        onInit() {
-            this.updateTime()
-            this.timer = setInterval(this.updateTime, 1000)
-        },
-        updateTime: function () {
-            var nowTime = new Date()
-            this.hour = nowTime.getHours()
-            this.minute = nowTime.getMinutes()
-            this.second = nowTime.getSeconds()
-            if (this.hour < 10) {
-                this.hour = '0' + this.hour
-            }
-            if (this.minute < 10) {
-                this.minute = '0' + this.minute
-            }
-            if (this.second < 10) {
-                this.second = '0' + this.second
-            }
-        },
-        onDestroy() {
-            clearInterval(this.timer);
-        }
-    }
-    ```

-应用首页主要展示城市的空气质量概况。首页总共有两屏（可以根据需求设置多屏），每屏显示一个城市的空气质量信息：主要包括AQI指数、城市名称、污染物指数、更新时间和信息来源等数据。
-
-从第一章节中的[显示效果图](概述-6.md#fig18250512195914)分析可知，首页由三部分组成：
-
--   标题栏：位于页面正上方，位置固定，包括应用退出按钮和页面标题。
--   信息栏：主要展示城市的空气信息指标等内容；该页面根据用户需求可设置多屏，且能循环滑动。
--   页面位置指示器：主要功能是标识当前页面，位置固定在页面底部的中间。
-
-综上，我们可搭建一个纵向三行排列的弹性页面布局来实现首页的功能。
-
-1.  在hml文件中添加一个根节点div，注意每个hml文件中有且只能有一个根节点，代码如下：
-
-    ```
-    <div class="container">
-    </div>
-    ```
-
-    class="container"表示组件使用的样式，container是index.css文件中的一个样式类，代码如下：
-
-    ```
-    .container {    
-        flex-direction: column;
-        height: 480px;
-        width: 960px;
-    }
-    ```
-
-    在这个样式类中，我们分别设置了根组件div的高度和宽度（注意在应用的开发过程中，除部分组件（text）外必须显式指定组件的高度和宽度，否则可能无法显示）、并将flex-direction属性设置为column，该属性表示div的子组件是垂直方向从上到下排列；这样就可以实现本节开头所说的纵向三行排列的弹性页面布局。
-
-2.  实现标题栏：标题栏包括一个退出按钮和一个标题，两个控件是横向排列；首先添加一个div，并设置flex-direction的属性为row，表示子组件是水平方向从左往右排列；然后依次添加一个image和text组件，代码如下：
-
-    ```
-    <div class="container">    
-        <div class="header" onclick="exitApp">        
-            <image class="back" src="common/ic_back.png"></image>        
-            <text class="title">            
-                空气质量        
-             </text>    
-        </div>
-    </div>
-    ```
-
-    设置组件的高度、边距、颜色等属性。
-
-    ```
-    .header {    
-        width: 960px;
-        height: 72px;
-    }
-    .back {    
-        width: 36px;
-        height: 36px;
-        margin-left: 39px;
-        margin-top: 23px;
-    }
-    .title {    
-        width: 296px;
-        height: 40px;
-        margin-top: 20px;
-        margin-left: 21px;
-        color: #e6e6e6;
-    }
-    ```
-
-    onclick="exitApp" 设置了div组件的click事件，当在标题栏上触发点击事件时，就会执行函数exitApp，该函数位于index.js文件中，代码如下：
-
-    ```
-    exitApp() {  
-        console.log('start exit');  
-        app.terminate();  
-        console.log('end exit');
-    }
-    ```
-
-    app.terminate\(\)函数实现了程序退出功能；在使用该函数前，需要引入app模块，在js文件的最上方写如下代码：
-
-    ```
-    import app from '@system.app'
-    ```
-
-    代码编写完成后，在模拟器中运行项目，显示效果如下图所示：
-
-    **图 1**  标题栏效果<a name="fig14273162465317"></a>  
-    ![](figures/标题栏效果.png "标题栏效果")
-
-3.  实现城市空气质量信息的多屏左右滑动，需要使用“swiper”组件。
-
-    在根节点中添加一个子节点swiper，代码片段如下：
-
-    ```
-    <div class="container">    
-        <div class="header" onclick="exitApp">        
-            <image class="back" src="common/ic_back.png"></image>        
-            <text class="title">            
-                空气质量        
-            </text>    
-        </div>    
-        <swiper class="swiper" index="{{swiperPage}}" duration="500" onchange="swiperChange">
-        </swiper>
-    </div>
-    ```
-
-    -   class="swiper"设置了组件的高度和宽度，代码如下：
-
-        ```
-        .swiper {
-            height: 385px;
-            width: 960px;
-        }
-        ```
-
-
-    -   index="\{\{swiperPage\}\}" duration="500" onchange="swiperChange" 这些代码用来设置组件的属性和事件。其中，duration="500" 表示设置swiper的页面滑动的动画时长为500ms。
-    -   index="\{\{swiperPage\}\}"设置了swiper子组件索引值，\{\{swiperPage\}\}这种写法表示index的值是和js代码中的swiperPage变量动态绑定的，index的值会随着swiperPage变动而改变。
-    -   onchange="swiperChange" 设置了swiper组件的change事件和函数swiperChange绑定，对应的js代码如下：
-
-        ```
-        //引入router模块，用户页面跳转
-        import router from'@system.router'
-        import app from '@system.app'
-        
-        export default {
-            //定义参数
-            data: {
-              //默认是第一页
-              swiperPage: 0 
-            },
-            onInit () {
-            },
-            exitApp(){  
-                console.log('start exit');  
-                app.terminate();  
-                console.log('end exit');
-            },
-            //swiper滑动回调事件，保存当前swiper的index值，每次滑动都会将index值保存在swiperPage变量中
-            swiperChange (e) {
-                this.swiperPage = e.index;
-            }
-        }
-        ```

-
-4.  设置一个城市的空气质量信息为一屏，在一屏内，要展示多种信息，分别使用不同的控件进行展示。
-
-    在swiper中添加两个子组件stack（绝对布局），每个stack组件内分别添加text、image、progress等组件来显示对应的信息 ，页面结构如下：
-
-    ```
-     <swiper class="swiper" index="{{swiperPage}}" duration="500" onchange="swiperChange">
-        <!--第一屏-->
-        <stack class="swiper">
-            <text></text>------空气质量
-            <text></text>------城市名称
-            <progress></progress>-----进度条
-            <image></image>-------云朵图片
-            <text></text>--------AQI数值
-            <text>AQI</text>------AQI
-            <div>--------空气指标详细信息
-            </div>
-            <div>--------更新时间和网站等信息
-            </div>
-        </stack>
-        <!--第二屏-->
-        <stack class="container">
-            <text></text>
-            <text></text>
-            <progress></progress>
-            <image></image>
-            <text></text>
-            <text></text>
-            <div></div>    
-        </stack>
-    </swiper>
-    ```
-
-    代码编写完成后，模拟器运行效果如下：

-    ![](figures/标题栏和信息栏效果.png "标题栏和信息栏效果")
-
-5.  添加页面位置指示器：由于当前swiper不支持设置indicator，需要开发者自己来实现该效果。在根节点中添加一个子组件div，并设置相应样式；然后在该div中添加两个子组件div，设置两个div的border-radius，并在swiper滑动事件中动态改变对应div的背景色来实现该效果。
-
-    ```
-    <div class="images">    
-        <div class="circle-div" style="background-color: {{iconcheckedColor}};"></div>    
-        <div class="circle-div" style="background-color: {{iconUncheckedColor}};margin-left: 36px;"></div>
-    </div>
-    ```

-    ![](figures/页面位置指示器效果图.png "页面位置指示器效果图")
-
-6.  所有组件设置样式、动画效果和数据动态绑定，完整代码如下所示：
-
-    -   **index.hml文件**
-
-    ```
-    <div class="container">
-        <div class="header" onclick="exitApp">

-    -   **index.css文件**
-
-    css文件中定义了许多class，每个class用于定义组件的位置、大小、字体、颜色、背景色等信息。同时，每一个子组件都叠加在父组件中，父组件的样式会影响子组件的呈现。

-            cam_ = &c;
-        }
-        void OnCreateFailed(const std::string cameraId, int32_t errorCode) override {}
-        void OnReleased(Camera &c) override {}
-    };
-    ```
-
-4.  创建CameraKit，用于创建和获取camera信息。
-
-    ```
-    CameraKit *camKit = CameraKit::GetInstance();
-    list<string> camList = camKit->GetCameraIds();
-    string camId;
-    for (auto &cam : camList) {
-        cout << "camera name:" << cam << endl;
-        const CameraAbility *ability = camKit->GetCameraAbility(cam);
-        /* find camera which fits user's ability */
-        list<CameraPicSize> sizeList = ability->GetSupportedSizes(0);
-        if (find(sizeList.begin(), sizeList.end(), CAM_PIC_1080P) != sizeList.end()) {
-            camId = cam;
-            break;
-        }
-    }
-    ```
-
-5.  创建Camera实例。
-
-    ```
-    EventHandler eventHdlr; // Create a thread to handle callback events
-    SampleCameraStateMng CamStateMng(eventHdlr);
-    
-    camKit->CreateCamera(camId, CamStateMng, eventHdlr);
-    ```
-
-6.  根据[步骤1](#zh-cn_topic_0000001052170554_li378084192111)、[步骤2](#zh-cn_topic_0000001052170554_li8716104682913)、[步骤3](#zh-cn_topic_0000001052170554_li6671035102514)中的回调设计，camera实例创建成功后会进行配置操作，主流程中app需要设计同步机制。
-
-    ```
-    void OnCreated(Camera &c) override
-    {
-        cout << "Sample recv OnCreate camera." << endl;
-        auto config = CameraConfig::CreateCameraConfig();
-        config->SetFrameStateCallback(&fsCb_, &eventHdlr_);
-        c.Configure(*config);
-        cam_ = &c;
-    }
-    
-    void Capture()
-    {
-        if (cam_ == nullptr) {
-            cout << "Camera is not ready." << endl;
-            return;
-        }
-        FrameConfig *fc = new FrameConfig(FRAME_CONFIG_CAPTURE);
-        Surface *surface = Surface::CreateSurface();
-        if (surface == nullptr) {
-            delete fc;
-        }
-        surface->SetWidthAndHeight(1920, 1080); /* 1920:width,1080:height */
-        fc->AddSurface(*surface);
-        cam_->TriggerSingleCapture(*fc);
-    }
-    ```

-    ```
-    class SampleCameraStateMng : public CameraStateCallback {

-        SampleCameraStateMng(EventHandler &eventHdlr) : eventHdlr_(eventHdlr) {}
-        ~SampleCameraStateMng()
-        {

-        void OnCreateFailed(const std::string cameraId, int32_t errorCode) override {}
-        void OnReleased(Camera &c) override {}
-    };
-    ```
-
-4.  创建CameraKit，用于创建和获取camera信息。
-
-    ```
-    CameraKit *camKit = CameraKit::GetInstance();
-    list<string> camList = camKit->GetCameraIds();
-    string camId;
-    for (auto &cam : camList) {
-        cout << "camera name:" << cam << endl;
-        const CameraAbility *ability = camKit->GetCameraAbility(cam);
-        /* find camera which fits user's ability */
-        list<CameraPicSize> sizeList = ability->GetSupportedSizes(0);
-        if (find(sizeList.begin(), sizeList.end(), CAM_PIC_1080P) != sizeList.end()) {
-            camId = cam;
-            break;
-        }
-    }
-    ```
-
-5.  创建Camera实例。
-
-    ```
-    EventHandler eventHdlr; // Create a thread to handle callback events
-    SampleCameraStateMng CamStateMng(eventHdlr);
-    
-    camKit->CreateCamera(camId, CamStateMng, eventHdlr);
-    ```
-
-6.  根据[步骤1](#zh-cn_topic_0000001052170554_li378084192111)、[步骤2](#zh-cn_topic_0000001052170554_li8716104682913)、[步骤3](#zh-cn_topic_0000001052170554_li6671035102514)中的回调设计，camera实例创建成功后会进行配置操作，主流程中app需要设计同步机制。
-
-    ```
-    void OnCreated(Camera &c) override
-    {
-        cout << "Sample recv OnCreate camera." << endl;
-        auto config = CameraConfig::CreateCameraConfig();
-        config->SetFrameStateCallback(&fsCb_, &eventHdlr_);
-        c.Configure(*config);
-        cam_ = &c;
-    }
-    
-    void Capture()
-    {
-        if (cam_ == nullptr) {
-            cout << "Camera is not ready." << endl;
-            return;
-        }
-        FrameConfig *fc = new FrameConfig(FRAME_CONFIG_CAPTURE);
-        Surface *surface = Surface::CreateSurface();
-        if (surface == nullptr) {
-            delete fc;
-        }
-        surface->SetWidthAndHeight(1920, 1080); /* 1920:width,1080:height */
-        fc->AddSurface(*surface);
-        cam_->TriggerSingleCapture(*fc);
-    }
-    ```

-2.  器件层驱动初始化及注册驱动至HDF框架
-
-    示例代码路径：./drivers/framework/model/input/driver/touchscreen/touch\_gt911.c
-
-    ```
-    static int32_t HdfGoodixChipInit(struct HdfDeviceObject *device)
-    {
-        ...
-        /* 器件配置结构体内存申请、配置信息解析及挂载 */
-        chipCfg = ChipConfigInstance(device);
-        ...
-        /* 器件实例化 */
-        chipDev = ChipDeviceInstance();
-        ...
-        /* 器件信息挂载及器件私有操作挂载 */
-        chipDev->chipCfg = chipCfg;
-        chipDev->ops = &g_gt911ChipOps;
-        ...
-        /* 注册器件驱动至平台驱动 */
-        RegisterChipDevice(chipDev);
-        ...
-    }
-    struct HdfDriverEntry g_touchGoodixChipEntry = {
-        .moduleVersion = 1,
-        .moduleName = "HDF_TOUCH_GT911",   // 该moduleName与device_info.hcs文件中器件驱动层的moduleName信息相匹配
-        .Init = HdfGoodixChipInit,         // 器件驱动初始化函数
-    };
-    HDF_INIT(g_touchGoodixChipEntry);      // 注册器件驱动至HDF框架
-    ```
-
-    器件私有驱动层主要实现了各器件厂商差异较大的部分，如器件休眠唤醒、数据解析以及固件升级等。
-
-    至此，基于HDF框架及Input模型的触摸屏驱动适配完成。

-示例中“touchConfig”包含了“touch0”，"touch0"包含了“boardConfig”与“chipConfig”；“boardConfig”字段包含了Hi3516DV300板级硬件信息，“chipConfig”包含了触摸屏器件的私有信息，如果需要替换触摸屏器件，重新配置“chipConfig”对应的字段信息即可。同时产品可以配置多款触摸屏，示例中用“touch0”代表了套件中默认的触摸屏的硬件接口以及器件的配置信息，如产品需要配置副屏，可在与“touch0”并列的位置配置“touch1”的信息。

-                }
-            }
-
-            device_touch_chip :: device {                 // Input器件驱动层信息
-                device0 :: deviceNode {
-                    policy = 0;                           // 向内核用户态均不发布服务
-                    priority = 130;                       // input器件驱动优先级默认为130
-                    preload = 0;                          // 加载该驱动
-                    permission = 0660;                    // 驱动创建设备节点权限
-                    moduleName = "HDF_TOUCH_GT911";       // 与驱动入口的moduleName匹配
-                    serviceName = "hdf_touch_gt911_service";// HDF框架生成的节点名
-                    deviceMatchAttr = "zsj_gt911_5p5";    //与私有配置信息中的“match_attr”字段保持一致
-                }
-            }
-  }
-```
-
-该配置文件中需要重点关注的字段有：
-
-“priority”决定驱动加载顺序；
-
-“preload”决定驱动是否加载；
-
-“moduleName ”需要与驱动注册入口处的“moduleName ”字段保持一致；
-
-“serviceName ”HDF框架依据该字段创建节点名；
-
-“deviceMatchAttr ”需要与私有配置信息中的“match\_attr”字段保持一致。
-
-通过配置设备描述信息，使得HDF框架通过moduleName与注册至驱动入口的代码相匹配，保证了驱动的正常加载，通过priority字段保证了各驱动的加载顺序。

-OpenHarmony致力于打造一套更加开放完善的IoT生态系统，为此OpenHarmony规划了一组目录，用于将各厂商的SDK集成到OpenHarmony中。本文档基于Hi3861开发板，向平台开发者介绍将SDK集成到OpenHarmony的方法。
-
-## 规划目录结构<a name="section1736472718351"></a>
-
-三方SDK通常由静态库和适配代码构成。SDK的业务逻辑通过硬件模组工具链编译得到静态库libs，每款模组都有其对应的libs。SDK的南向API与OpenHarmony 的API存在使用差异，该差异可通过adapter适配代码屏蔽，不同模组可共用一套adapter。
-
-基于以上特征，在OpenHarmony目录结构中，可以对三方SDK目录做如下划分。
-
--   适配代码adapter，放置到domains/iot/link/ 目录下，与模组解耦。
--   业务库libs，放置到device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/ 目录下，与模组绑定。
-
-平台开发者在适配前，务必先依次完成以下步骤，下面以demolink SDK举例，进行介绍。
-
-1.  创建厂商目录，domains/iot/link/demolink/、device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/demolink/ ，用于厂商隔离。
-2.  创建domains/iot/link/demolink/BUILD.gn ，用于构建适配代码。
-3.  创建device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/demolink/libs/ 目录，用于存放业务库libs。

-```
-
-## 构建业务libs<a name="section442815485351"></a>
-
-平台SDK业务一般以静态库的形式提供，平台厂商在获取到OpenHarmony代码后，需要根据对应的硬件模组vendor，编译业务libs，并将编译结果放置在device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/demolink/libs/ 目录下。下面介绍业务libs的构建方法。
-
-OpenHarmony已规划用于编译业务libs的目录domains/iot/link/libbuild/ ，该目录中包含domains/iot/link/libbuild/BUILD.gn和domains/iot/link/BUILD.gn文件，目录结构如下。
-
-```
-.
-└── domains
-    └── iot
-        └── link
-            ├── demolink
-            │   └── BUILD.gn
-            ├── libbuild
-            │   └── BUILD.gn
-            └── BUILD.gn
-```
-
-平台开发者在构建libs前，务必先完成如下步骤。
-
-1.  在domains/iot/link/libbuild/ 目录下放置业务源码文件，包括.c和.h文件。
-
-    ```
-    .
-    └── domains
-        └── iot
-            └── link
-                ├── demolink
-                │   ├── demosdk_adapter.c
-                │   ├── demosdk_adapter.h
-                │   └── BUILD.gn
-                ├── libbuild
-                │   ├── demosdk.c
-                │   ├── demosdk.h
-                │   └── BUILD.gn
-                └── BUILD.gn
-    ```
-
-2.  适配domains/iot/link/libbuild/BUILD.gn，在编译完成后还原该文件。
-
-    在BUILD.gn中，sources为需要参与构建的源文件，include\_dirs为依赖的头文件路径，构建的目标结果是生成静态库libdemosdk.a。
-
-    ```
-    static_library("demosdk") {
-        sources = [
-            "demosdk.c"
-        ]
-        include_dirs = [
-            "//domains/iot/link/libbuild",
-            "//domains/iot/link/demolink"
-        ]
-    }
-    ```
-
-3.  适配domains/iot/link/BUILD.gn，在编译完成后还原该文件。
-
-    此BUILD.gn文件用于指定构建条目，需要在features中填入所有需参与编译的静态库条目，使domains/iot/link/libbuild/BUILD.gn参与到构建中来。
-
-    ```
-    import("//build/lite/config/subsystem/lite_subsystem.gni")
-    import("//build/lite/config/component/lite_component.gni")
-    lite_subsystem("iot") {
-        subsystem_components = [
-            ":link"
-        ]
-    }
-    lite_component("link") {
-        features = [
-            "libbuild:demosdk"
-        ]
-    }
-    ```
-
-
-完成以上3点后，需在代码根目录下执行命令“hb build -T //domains/iot/link:iot”，等待执行完成，检查out/hispark\_pegasus/wifiiot\_hispark\_pegasus/libs/目录下是否生成了目标库文件。
-
-![](figures/zh-cn_image_0000001078563230.png)
-
-将库文件拷贝到device/hisilicon/hispark\_pegasus/sdk\_liteos/3rd\_sdk/demolink/libs/ 目录下，并将domains/iot/link/libbuild/ 目录中的.c和.h文件清除。

-## 代码编写<a name="section830417531286"></a>
-
-平台SDK中使用的API通常与OpenHarmony API存在差异，无法直接使用，需要一层适配代码adapter进行中间转换。本节以domains/iot/link/demolink/demosdk\_adapter.c中的任务创建接口DemoSdkCreateTask举例，向开发者演示如何在OpenHarmony上编写适配代码。
-
-1.  查看待适配接口DemoSdkCreateTask的描述、参数、返回值。
-
-    ```
-    struct TaskPara {
-        char *name;
-        void *(*func)(char* arg);
-        void *arg;
-        unsigned char prio;
-        unsigned int size;
-    };
-    
-    /*
-     * IoT OS 创建线程接口
-     * 返回值: 返回0 成功, 其他 失败
-     */
-    int DemoSdkCreateTask(unsigned int *handle, const struct TaskPara *para);
-    ```
-
-2.  查看OpenHarmony API接口文档，选取一个功能类似的接口，并比对参数及用法上的差异。例如本文选取osThreadNew ，通过和DemoSdkCreateTask接口比对，可以发现两接口依赖的参数基本一致，只是参数所归属的结构体不同。
-
-    ```
-    typedef struct {
-        const char                   *name;   ///< name of the thread
-        uint32_t                 attr_bits;   ///< attribute bits
-        void                      *cb_mem;    ///< memory for control block
-        uint32_t                   cb_size;   ///< size of provided memory for control block
-        void                   *stack_mem;    ///< memory for stack
-        uint32_t                stack_size;   ///< size of stack
-        osPriority_t              priority;   ///< initial thread priority (default: osPriorityNormal)
-        TZ_ModuleId_t            tz_module;   ///< TrustZone module identifier
-        uint32_t                  reserved;   ///< reserved (must be 0)
-    } osThreadAttr_t;
-    
-    /// Create a thread and add it to Active Threads.
-    /// \param[in]     func          thread function.
-    /// \param[in]     argument      pointer that is passed to the thread function as start argument.
-    /// \param[in]     attr          thread attributes; NULL: default values.
-    /// \return thread ID for reference by other functions or NULL in case of error.
-    osThreadId_t osThreadNew (osThreadFunc_t func, void *argument, const osThreadAttr_t *attr);
-    ```
-
-3.  完成代码差异转换。
-
-    ```
-    int DemoSdkCreateTask(unsigned int *handle, const struct TaskPara *para)
-    {
-        osThreadAttr_t attr = {0};
-        osThreadId_t threadId;
-        if (handle == 0 || para == 0) {
-            return DEMOSDK_ERR;
-        }
-        if (para->func == 0) {
-            return DEMOSDK_ERR;
-        }
-        if (para->name == 0) {
-            return DEMOSDK_ERR;
-        }
-        attr.name = para->name;
-        attr.priority = para->prio;
-        attr.stack_size = para->size;
-        threadId = osThreadNew((osThreadFunc_t)para->func, para->arg, &attr);
-        if (threadId == 0) {
-            printf("osThreadNew fail\n");
-            return DEMOSDK_ERR;
-        }
-        *(unsigned int *)handle = (unsigned int)threadId;
-        return DEMOSDK_OK;
-    }
-    ```
-
-
-## 脚本编写<a name="section13500201173710"></a>
-
-开发者在完成代码适配后，还需要在adapter同级目录下新建BUILD.gn文件。该文件可在整包构建时，将适配代码编译成静态库，并链接到bin包中去。在domains/iot/link/demolink/BUILD.gn中，sources中为需要参与构建的源文件，include\_dirs中为依赖的头文件路径，构建目标结果是生产静态库libdemolinkadapter.a。
-
-```
-import("//build/lite/config/component/lite_component.gni")
-static_library("demolinkadapter") {
-    sources = [
-        "demosdk_adapter.c"
-    ]
-    include_dirs = [
-        "//kernel/liteos-m/kal/cmsis",
-        "//domains/iot/link/demolink"
-    ]
-}
-```
-
-修改domains/iot/link/BUILD.gn文件，使domain/iot/hilink/BUILD.gn参与到构建系统中。
-
-```
-import("//build/lite/config/subsystem/lite_subsystem.gni")
-import("//build/lite/config/component/lite_component.gni")
-lite_subsystem("iot") {
-    subsystem_components = [
-        ":link"
-    ]
-}
-lite_component("link") {
-    features = [
-        "demolink:demolinkadapter"
-    ]
-}
-```
-
-## 编写业务代码<a name="section8754114803918"></a>
-
-业务libs库和适配代码准备就绪后，还需要编写业务入口函数，调起三方SDK的业务入口。
-
-下面以demolink举例，介绍如何在applications/sample/wifi-iot/app/路径下编写代码，调起demosdk的入口函数。
-
-1.  目录创建
-
-    开发者编写业务时，务必先在applications/sample/wifi-iot/app/ 路径下新建一个目录（或一套目录结构），用于存放业务源码文件。
-
-    例如：在app下新增业务目录demolink，并在其中创建业务入口代码helloworld.c和编译构建文件BUILD.gn，如下。
-
-    ```
-    .
-    └── applications
-        └── sample
-            └── wifi-iot
-                └── app
-                    │── demolink
-                    │    │── helloworld.c
-                    │    └── BUILD.gn
-                    └── BUILD.gn
-    ```
-
-2.  编写业务代码。
-
-    在helloworld.c文件中编写业务入口函数DemoSdkMain，并调起demolink的业务DemoSdkEntry，最后通过SYS\_RUN\(\)调用入口函数完成业务启动。
-
-    ```
-    #include "hos_init.h"
-    #include "demosdk.h"
-    
-    void DemoSdkMain(void)
-    {
-        DemoSdkEntry();
-    }
-    
-    SYS_RUN(DemoSdkMain);
-    ```
-
-3.  编写构建脚本
-
-    新增applications/sample/wifi-iot/app/demolink/BUILD.gn文件，指定源码和头文件路径，编译输出静态库文件libexample\_demolink.a。
-
-    ```
-    static_library("example_demolink") {
-        sources = [
-            "helloworld.c"
-        ]
-        include_dirs = [
-            "//utils/native/lite/include",
-            "//domains/iot/link/libbuild"
-        ]
-    }
-    ```
-
-    修改applications/sample/wifi-iot/app/BUILD.gn，使demolink参与编译。
-
-    ```
-    import("//build/lite/config/component/lite_component.gni")
-    lite_component("app") {
-        features = [
-            "demolink:example_demolink"
-        ]
-    }
-    ```
-
-
-## 运行<a name="section7737749184012"></a>
-
-在代码根目录下，执行命令“hb build”编译输出版本包。最后启动运行，运行结果如图所示，与demolink预期相符。
-
-```
-ready to OS start
-sdk ver:Hi3861V100R001C00SPC024 2020-08-05 16:30:00
-formatting spiffs...
-FileSystem mount ok.
-wifi init success!
-it is demosdk entry.
-it is demo biz: hello world.
-it is demo biz: hello world.
-```
-
-## 结束<a name="section153301392411"></a>
-
-至此，三方SDK集成已介绍完毕。

-**【写作样例】**
-
-1. 构造音频流参数的数据结构AudioStreamInfo，推荐使用AudioStreamInfo.Builder类来构造，模板如下，模板中设置的均为AudioStreamInfo.Builder类的默认值，根据音频流的具体规格来设置具体参数。
-   ```
-   AudioStreamInfo audioStreamInfo = new AudioStreamInfo.Builder().sampleRate(    AudioStreamInfo.SAMPLE_RATE_UNSPECIFIED)    .audioStreamFlag(AudioStreamInfo.AudioStreamFlag.AUDIO_STREAM_FLAG_NONE)    .encodingFormat(AudioStreamInfo.EncodingFormat.ENCODING_INVALID)    .channelMask(AudioStreamInfo.ChannelMask.CHANNEL_INVALID)    .streamUsage(AudioStreamInfo.StreamUsage.STREAM_USAGE_UNKNOWN)    .build();
-   ```
-
-    以真实的播放pcm流为例：
-      ```
-      AudioStreamInfo audioStreamInfo = new AudioStreamInfo.Builder().sampleRate(44100)//44.1kHz    .audioStreamFlag(AudioStreamInfo.AudioStreamFlag.AUDIO_STREAM_FLAG_MAY_DUCK)//混音    .encodingFormat(AudioStreamInfo.EncodingFormat.ENCODING_PCM_16BIT)//16-bit PCM    .channelMask(AudioStreamInfo.ChannelMask.CHANNEL_OUT_STEREO)//双声道    .streamUsage(AudioStreamInfo.StreamUsage.STREAM_USAGE_MEDIA)//媒体类音频    .build();
-      ```
-
-2. 使用步骤1创建的音频流构建音频播放的参数结构AudioRendererInfo，推荐使用AudioRendererInfo.Builder类来构造，模板如下，模板中设置的均为AudioRendererInfo.Builder类的默认值，根据音频播放的具体规格来设置具体参数。
-   ```
-   AudioRendererInfo audioRendererInfo = new AudioRendererInfo.Builder().audioStreamInfo(audioStreamInfo)    .audioStreamOutputFlag(AudioRendererInfo.AudioStreamOutputFlag.AUDIO_STREAM_OUTPUT_FLAG_NONE)    .bufferSizeInBytes(0)    .distributedDeviceId("")    .isOffload(false)    .sessionID(AudioRendererInfo.SESSION_ID_UNSPECIFIED)    .build();
-   ```
-
-    以真实的播放pcm流为例：
-      ```
-      AudioRendererInfo audioRendererInfo = new AudioRendererInfo.Builder().audioStreamInfo(audioStreamInfo)    .audioStreamOutputFlag(AudioRendererInfo.AudioStreamOutputFlag.AUDIO_STREAM_OUTPUT_FLAG_DIRECT_PCM)//pcm格式的输出流    .bufferSizeInBytes(100)    .distributedDeviceId("E54***5E8")//使用分布式设备E54***5E8播放    .isOffload(false)//false表示分段传输buffer并播放，true表示整个音频流一次性传输到HAL层播放    .build();
-      ```
-
-3. 根据要播放音频流指定PlayMode，不同的PlayMode在写数据时存在差异，详情见步骤7，其余播放流程是无区别的。并通过构造函数获取AudioRenderer类的实例化对象。
-   ....
-
-4. 播放任务结束后，调用AudioRenderer实例化对象的release()释放资源。
-
-
-## 调测验证（可选）
-
-** *【写作要求】***
-
-*可选。* *描述开发完成后，进行调测验证，确保最终操作成功。* *操作步骤要求同“开发指导”，其他具体写作要求见下，完成写作后，请逐项自检下。*
-
-| 要求项 | 内容要求 | 是否满足 |
-| -------- | -------- | -------- |
-| L1.1 | 仅进行最后的业务调测，每个小任务的操作结果，在开发步骤执行完成后，及时验证操作结果。 |  |
-| L1.2 | 明确开发成功标准。 |  |

-
-
-鸿蒙系统音频模块支持音频业务的开发，提供音频相关的功能，主要包括音频播放、音频采集、音量管理和短音播放等。
-
-
-在进行应用的开发前，开发者应了解以下基本概念：
-
-
-- 采样
-  采样就是把模拟信号数字化的过程，所有的模拟信号都需要通过采样转换为可以用0101来表示的数字信号。
-
-- 采样率
-  采样率为每秒从连续信号中提取并组成离散信号的采样次数，单位用赫兹（Hz）来表示。通常人耳能听到频率范围大约在20Hz～20kHz之间的声音。常用的音频采样频率有：8kHz、11.025kHz、22.05kHz、16kHz、37.8kHz、44.1kHz、48kHz、96kHz、192kHz等。
-
-- 声道
-  声道是指声音在录制或播放时在不同空间位置采集或回放的相互独立的音频信号，所以声道数也就是声音录制时的音源数量或回放时相应的扬声器数量。
-
-- 音频帧
-  音频数据是流式的，本身没有明确的一帧帧的概念，在实际的应用中，为了音频算法处理/传输的方便，一般约定俗成取2.5ms~60ms为单位的数据量为一帧音频。这个时间被称之为“采样时间”，其长度没有特别的标准，它是根据编解码器和具体应用的需求来决定的。
-
-
-## 运作机制
-
-*【 **写作要求】***
-
-*可选。如果机制比较简单，通过前面基本概念就可以说清楚，此章节可以不用提供，删除标题即可。*
-
-*描述实现原理介绍机制，如关键步骤相关接口调用时机和触发时机，帮助开发者了解该功能的基本运作原理，以便更好的理解开发任务和定位问题。*
-
-* 写作要求见下，完成写作后，请逐项自检。*
-
-| 要求项 | 内容要求 | 是否满足 |
-| -------- | -------- | -------- |
-| C.1.1 | 仅描述开发任务相关的原理。 |  |
-| C.1.2 | 尽量图文配合，一般使用时序图、流程图等形式。文字描述与图形描述匹配。 |  |
-| C.1.3 | 原理要黑盒描述，注意不要泄密。 |  |
-

-
-- 信号量初始化，为配置的N个信号量申请内存（N值可以由用户自行配置，受内存限制），并把所有的信号量初始化成未使用，并加入到未使用链表中供系统使用。
-
-- 信号量创建，从未使用的信号量链表中获取一个信号量资源，并设定初值。
-
-- 信号量申请，若其计数器值大于0，则直接减1返回成功。否则任务阻塞，等待其它任务释放该信号量，等待的超时时间可设定。当任务被一个信号量阻塞时，将该任务挂到信号量等待任务队列的队尾。
-
-- 信号量释放，若没有任务等待该信号量，则直接将计数器加1返回。否则唤醒该信号量等待任务队列上的第一个任务。
-
-- 信号量删除，将正在使用的信号量置为未使用信号量，并挂回到未使用链表。
-
-- 信号量允许多个任务在同一时刻访问同一资源，但会限制同一时刻访问此资源的最大任务数目。访问同一资源的任务数达到该资源的最大数量时，会阻塞其他试图获取该资源的任务，直到有任务释放该信号量。

-  【写作样例-2】
-
-  **互斥锁运作原理**
-
-  多任务环境下会存在多个任务访问同一公共资源的场景，而有些公共资源是非共享的，需要任务进行独占式处理。互斥锁怎样来避免这种冲突呢？
-
-  用互斥锁处理非共享资源的同步访问时，如果有任务访问该资源，则互斥锁为加锁状态。此时其他任务如果想访问这个公共资源则会被阻塞，直到互斥锁被持有该锁的任务释放后，其他任务才能重新访问该公共资源，此时互斥锁再次上锁，如此确保同一时刻只有一个任务正在访问这个公共资源，保证了公共资源操作的完整性。

-
-## 约束与限制
-
-* **【写作要求】***
-
-*必选。* *描述本开发任务过程中* *的约束条件，以及此操作约束带来相应的负面影响，包括但不限于如下几方面：*
-
-* **功能限制：***
-
-- * 功能使用范围（明确不支持的场景）。*
-
-- *规格限制。*
-
-* **操作限制** **：***
-
-- * 已知问题的操作。*
-
-- * 潜在风险的操作（如引起性能降低）。*
-
-- * 引起性能降低的操作*。
-
-* 写作要求见下，完成写作后，请逐项自检。*
-
-| 要求项 | 内容要求 | 是否满足 |
-| -------- | -------- | -------- |
-| D.1.1 | 明确功能限制或操作限制。 |  |
-| D.1.2 | 约束对指导任务开发有影响或体验有感知，否则不用体现。 |  |
-| D.1.3 | 容易出错的操作在步骤里描述，不在此体现。 |  |
-
-**【写作样例】**
-
-**互斥锁的约束与限制：**
-
-- 两个任务不能对同一把互斥锁加锁。如果某任务对已被持有的互斥锁加锁，则该任务会被挂起，直到持有该锁的任务对互斥锁解锁，才能执行对这把互斥锁的加锁操作。
-
-- 互斥锁不能在中断服务程序中使用。
-
-- Huawei LiteOS作为实时操作系统需要保证任务调度的实时性，尽量避免任务的长时间阻塞，因此在获得互斥锁之后，应该尽快释放互斥锁。
-
-- 持有互斥锁的过程中，不得再调用LOS_TaskPriSet等接口更改持有互斥锁任务的优先级。

-CMSIS-RTOS2组件可以作为库或源代码提供（下图显示了库）。通过添加CMSIS-RTOS2组件（通常是一些配置文件），可以将基于CMSIS的应用程序扩展为具有RTOS功能。只需包含cmsis\_os2.h头文件就可以访问RTOS API函数，这使用户应用程序能够处理RTOS内核相关事件，而在更换内核时无需重新编译源代码。
-
-静态对象分配需要访问RTOS对象控制块定义。特定于实现的头文件（下图中的os\_xx .h）提供对此类控制块定义的访问。对于OpenHarmony LiteOS-M内核，由文件名以los\_开头的头文件提供，这些文件包含OpenHarmony LiteOS-M内核的这些定义。

-## 基本概念<a name="section1772629121418"></a>
-
-FAT文件系统是File Allocation Table（文件配置表）的简称，主要包括DBR区、FAT区、DATA区三个区域。其中，FAT区各个表项记录存储设备中对应簇的信息，包括簇是否被使用、文件下一个簇的编号、是否文件结尾等。FAT文件系统有FAT12、FAT16、FAT32等多种格式，其中，12、16、32表示对应格式中FAT表项的字节数。FAT文件系统支持多种介质，特别在可移动存储介质（U盘、SD卡、移动硬盘等）上广泛使用，使嵌入式设备和Windows、Linux等桌面系统保持很好的兼容性，方便用户管理操作文件。
-
-OpenHarmony内核支持FAT12、FAT16与FAT32三种格式的FAT文件系统，具有代码量小、资源占用小、可裁切、支持多种物理介质等特性，并且与Windows、Linux等系统保持兼容，支持多设备、多分区识别等功能。OpenHarmony内核支持硬盘多分区，可以在主分区以及逻辑分区上创建FAT文件系统。

-### 驱动适配<a name="section19174939191414"></a>
-
-FAT文件系统的使用需要底层MMC相关驱动的支持。在一个带MMC存储设备的板子上运行FATFS，需要：
-
-1、适配板端EMMC驱动，实现disk\_status、disk\_initialize、disk\_read、disk\_write、disk\_ioctl接口；
-
-2、新增fs\_config.h文件，配置FS\_MAX\_SS（存储设备最大sector大小）、FF\_VOLUME\_STRS（分区名）等信息，例如：
-
-```
-#define FF_VOLUME_STRS     "system", "inner", "update", "user"
-#define FS_MAX_SS          512
-#define FAT_MAX_OPEN_FILES 50
-```

-### 开发流程<a name="section131211626151513"></a>
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   FATFS文件与目录操作：
->    -   单个文件大小不超过4G。
->    -   支持同时打开的文件数最大为FAT\_MAX\_OPEN\_FILES，文件夹数最大为FAT\_MAX\_OPEN\_DIRS。
->    -   暂不支持根目录管理，文件/目录名均以分区名开头，例如“user/testfile”就是在“user”分区下名为“testfile”的文件或目录。
->    -   若需要同时多次打开同一文件，必须全部使用只读方式（O\_RDONLY）。以可写方式（O\_RDWR、O\_WRONLY等）只能打开一次。
->    -   读写指针未分离，例如以O\_APPEND（追加写）方式打开文件后，读指针也在文件尾，从头读文件前需要用户手动置位。
->    -   暂不支持文件与目录的权限管理。
->    -   stat及fstat接口暂不支持查询修改时间、创建时间和最后访问时间。微软FAT协议不支持1980年以前的时间。
->-   FATFS分区挂载与卸载：
->    -   支持以只读属性挂载分区。当mount函数的入参为MS\_RDONLY时，所有的带有写入的接口，如write、mkdir、unlink，以及非O\_RDONLY属性的open，将均被拒绝。
->    -   mount支持通过MS\_REMOUNT标记修改已挂载分区的权限。
->    -   在umount操作前，需确保所有目录及文件全部关闭。
->    -   umount2支持通过MNT\_FORCE参数强制关闭所有文件与文件夹并umount，但可能造成数据丢失，请谨慎使用。
->-   FATFS支持重新划分存储设备分区、格式化分区，对应接口为fatfs\_fdisk与fatfs\_format：
->    -   在fatfs\_format操作之前，若需要格式化的分区已挂载，需确保分区中的所有目录及文件全部关闭，并且分区umount。
->    -   在fatfs\_fdisk操作前，需要该设备中的所有分区均已umount。
->    -   fatfs\_fdisk与fatfs\_format会造成设备数据丢失，请谨慎使用。

-## 概述<a name="section18322139164413"></a>
-
-NFS是Network File System（网络文件系统）的缩写。它最大的功能是可以通过网络，让不同的机器、不同的操作系统彼此分享其他用户的文件。因此，用户可以简单地将它看做是一个文件系统服务，在一定程度上相当于Windows环境下的共享文件夹。
-
-NFS客户端用户，能够将网络远程的NFS服务端分享的目录挂载到本地端的机器中，运行程序和共享文件，但不占用当前的系统资源，所以，在本地端的机器看起来，远程服务端的目录就好像是自己的一个磁盘一样。
-
-## 注意事项<a name="section532912331467"></a>
-
--   当前NFS文件不支持权限控制，请在创建NFS目录和文件时使用777权限。
-
--   当前NFS文件不支读阻塞和写阻塞。
-
--   当前NFS文件不支持信号功能。
-
--   当前NFS文件系统mount路径长度（不包含IP的长度）不超过255个字符，超过时返回ENAMETOOLONG错误。
-
--   当前NFS文件支持的操作有：open, close, read, write, seek, dup, dup2, sync, opendir, closedir, readdir, readdir\_r, rewinddir,  scandir, statfs, remove, unlink, mkdir, rmdir, rename, stat, stat64, seek64, mmap, mount, umount。
-
--   当前NFS支持TCP和UDP两种传输层协议，默认使用TCP。
-
--   open打开一个文件，参数有O\_TRUNC时，必须同时拥有写的权限，才会将文件中的内容清空。
-
--   在文件未关闭的情况下，rename\(\)函数重命名A为B之后，不会改变文件fd。
-
--   NFS功能目前处于beta测试阶段，可能存在功能不稳定的情况，建议您不要用于正式商用产品当中。

-
-1.  **搭建NFS服务器**。
-
-    这里以Ubuntu操作系统为例，说明服务器端设置步骤。
-
-    1.  安装NFS服务器软件。
-
-        设置好Ubuntu系统的下载源，保证网络连接好的情况下执行：
-
-        ```
-        sudo apt-get install nfs-kernel-server
-        ```
-
-    2.  创建用于挂载的目录并设置完全权限
-
-        ```
-        mkdir /home/sqbin/nfs
-        sudo chmod 777 /home/sqbin/nfs
-        ```
-
-    3.  设置和启动NFS server。
-
-        修改NFS配置文件/etc/exports，添加如下一行：
-
-        ```
-        /home/sqbin/nfs *(rw,no_root_squash,async)
-        ```
-
-        其中/home/sqbin/nfs是NFS共享的根目录。
-
-        执行以下命令启动NFS server：
-
-        ```
-        sudo /etc/init.d/nfs-kernel-server start
-        ```
-
-        执行以下命令重启NFS server：
-
-        ```
-        sudo /etc/init.d/nfs-kernel-server restart
-        ```
-
-
-2.  **设置单板为NFS客户端**。
-
-    本指导中的NFS客户端指运行OpenHarmony内核的设备。
-
-    1.  硬件连接设置。
-
-        OpenHarmony内核设备连接到NFS服务器的网络。设置两者IP，使其处于同一网段。比如，设置NFS服务器的IP为10.67.212.178/24，设置OpenHarmony内核设备IP为10.67.212.3/24，注意：此IP为内网私有IP地址，用户使用时有差异，以用户实际IP为准。
-
-        OpenHarmony内核设备上的IP信息可通过ifconfig命令查看。
-
-    2.  启动网络，确保单板到NFS服务器之间的网络通畅。
-
-        启动以太网或者其他类型网络，使用ping命令检查到服务器的网络是否通畅。
-
-        ```
-        OHOS # ping 10.67.212.178
-        [0]Reply from 10.67.212.178: time=1ms TTL=63
-        [1]Reply from 10.67.212.178: time=0ms TTL=63
-        [2]Reply from 10.67.212.178: time=1ms TTL=63
-        [3]Reply from 10.67.212.178: time=1ms TTL=63
-        --- 10.67.212.178 ping statistics ---
-        4 packets transmitted, 4 received, 0 loss
-        ```
-
-        客户端NFS初始化，运行命令：
-
-        ```
-        OHOS # mkdir /nfs
-        OHOS # mount 10.67.212.178:/home/sqbin/nfs /nfs nfs 1011 1000
-        ```
-
-        将从串口得到如下回应信息，表明初始化NFS客户端成功。
-
-        ```
-        OHOS # mount 10.67.212.178:/home/sqbin/nfs /nfs nfs 1011 1000
-        Mount nfs on 10.67.212.178:/home/sqbin/nfs, uid:1011, gid:1000
-        Mount nfs finished.
-        ```
-
-        该命令将服务器10.67.212.178上的/home/sqbin/nfs目录mount在OpenHarmony内核设备上的/nfs上。
-
-        >![](public_sys-resources/icon-note.gif) **说明：** 
-        >本例默认nfs server已经配置可用，即示例中服务器10.67.212.178上的/home/sqbin/nfs已配置可访问。
-
-        mount命令的格式为：
-
-        ```
-        mount <SERVER_IP:SERVER_PATH> <CLIENT_PATH> nfs
-        ```
-
-        其中“SERVER\_IP“表示服务器的IP地址；“SERVER\_PATH“表示服务器端NFS共享目录路径；“CLIENT\_PATH“表示设备上的NFS路径。
-
-        如果不想有NFS访问权限限制，请在Linux命令行将NFS根目录权限设置成777：
-
-        ```
-        chmod -R 777 /home/sqbin/nfs
-        ```
-
-        至此，NFS客户端设置完毕。NFS文件系统已成功挂载。
-
-
-3.  **利用NFS共享文件**。
-
-    在NFS服务器下新建目录dir，并保存。在OpenHarmony内核下运行ls命令：
-
-    ```
-    OHOS # ls /nfs
-    ```
-
-    则可从串口得到如下回应：
-
-    ```
-    OHOS # ls /nfs 
-    Directory /nfs:                 
-    drwxr-xr-x 0        u:0     g:0     dir
-    ```
-
-    可见，刚刚在NFS服务器上新建的dir目录已同步到客户端\(OpenHarmony内核系统\)的/nfs目录，两者保持同步。
-
-    同样地，在客户端\(OpenHarmony内核系统\)上创建文件和目录，在NFS服务器上也可以访问，读者可自行体验。
-
-    **平台差异性：**
-
-    目前，NFS客户端仅支持NFS v3部分规范要求，因此对于规范支持不全的服务器，无法完全兼容。在开发测试过程中，建议使用Linux的NFS server，因为其对NFS支持很完善。

-# OpenHarmony开发板Patch使用指导<a name="ZH-CN_TOPIC_0000001081980461"></a>
-
-Patch文件位于工程项目源码路径：kernel/linux/patches/linux-4.19，存放特定芯片架构驱动补丁。
-
-如需使用特定芯片平台驱动的Patch，需要在内核仓代码完成对芯片平台驱动补丁合入。
-
-合入芯片平台驱动补丁，针对不同芯片平台合入对应的patch：
-
-以Hi3516dv300为例：
-
-```
-patch -p1 < device/hisilicon/hi3516dv300/sdk_linux/open_source/linux/hisi_linux-4.19_hos_l2.patch 
-```
-
->![](public_sys-resources/icon-notice.gif) **须知：** 
->由于OpenHarmony的编译构建流程中会拷贝kernel/linux-4.19的代码环境后进行打补丁动作，在使用OpenHarmony的版本级编译命令前，需要kernel/linux-4.19保持原代码环境。

--   [注意事项](#section12298165312328)
-
-OpenHarmony内核提供的Shell支持调试常用的基本功能，包含系统、文件、网络和动态加载相关命令。同时OpenHarmony内核的Shell支持添加新的命令，可以根据需求来进行定制。
-
--   系统相关命令：提供查询系统任务、内核信号量、系统软件定时器、CPU占用率、当前中断等相关信息的能力。
-
--   文件相关命令：支持基本的ls、cd等功能。
-
--   网络相关命令：支持查询接到开发板的其他设备的IP、查询本机IP、测试网络连接、设置开发板的AP和station模式等相关功能。
-
-    新增命令的详细流程可参见[开发指导](Shell命令开发指导.md)和[编程实例](Shell命令编程实例.md)。
-
-
-## 注意事项<a name="section12298165312328"></a>
-
-在使用Shell功能的过程中，需要注意以下几点：
-
--   Shell功能支持使用exec命令来运行可执行文件。
--   Shell功能支持默认模式下英文输入。如果出现用户在UTF-8格式下输入了中文字符的情况，只能通过回退三次来删除。
-
--   Shell功能支持shell命令、文件名及目录名的Tab键联想补全。若有多个匹配项，则根据共同字符， 打印多个匹配项。对于过多的匹配项（打印多于24行），将会进行打印询问（Display  all num  possibilities?（y/n）），用户可输入y选择全部打印，或输入n退出打印，选择全部打印并打印超过24行后，会进行--More--提示，此时按回车键继续打印，按q键退出（支持Ctrl+c退出\)。
-
--   Shell端工作目录与系统工作目录是分开的，即通过Shell端cd  pwd等命令是对Shell端工作目录进行操作，通过chdir getcwd等命令是对系统工作目录进行操作，两个工作目录相互之间没有联系。当文件系统操作命令入参是相对路径时要格外注意。
-
--   在使用网络Shell指令前，需要先调用tcpip\_init函数完成网络初始化并完成telnet连接后才能起作用，内核默认不初始化tcpip\_init。
-
--   不建议使用Shell命令对/dev目录下的设备文件进行操作，这可能会引起不可预知的结果。
-
--   Shell功能不符合POSIX标准，仅供调试使用。
-
-    >![](public_sys-resources/icon-notice.gif) **须知：** 
-    >Shell功能仅供调试使用，在Debug版本中开启（使用时通过menuconfig在配置项中开启"LOSCFG\_DEBUG\_VERSION"编译开关进行相关控制），商用产品中禁止包含该功能。

-
-新增Shell命令的典型开发流程如下：
-
-1.  包含如下头文件：
-
-    ```
-    #include "shell.h"
-    #include "shcmd.h"
-    ```
-
-2.  注册命令。用户可以选择静态注册命令方式和系统运行时动态注册命令方式，静态注册命令方式一般用在系统常用命令注册，动态注册命令方式一般用在用户命令注册。
-
-    1.  静态注册命令方式：
-
-        1.  通过宏的方式注册。
-
-            这个宏的原型为：
-
-            ```
-            SHELLCMD_ENTRY(l, cmdType, cmdKey, paraNum, cmdHook)
-            ```

-## 概述<a name="section132540468341"></a>
-
-## 基本概念<a name="section229417111227"></a>
-
-VFS是Virtual File System（虚拟文件系统）的缩写，它不是一个实际的文件系统，而是一个异构文件系统之上的软件粘合层，为用户提供统一的类Unix文件操作接口。
-
-由于不同类型的文件系统接口不统一，若系统中有多个文件系统类型，访问不同的文件系统就需要使用不同的非标准接口。而通过在系统中添加VFS层，提供统一的抽象接口，屏蔽了底层异构类型的文件系统的差异，使得访问文件系统的系统调用不用关心底层的存储介质和文件系统类型，提高开发效率。VFS和各个具体文件系统的关系如下：
-
-**图 1**  VFS和各个文件系统的关系<a name="fig633144419295"></a>  
-![](figures/VFS和各个文件系统的关系.png "VFS和各个文件系统的关系")
-
-OpenHarmony内核中，VFS框架是通过在内存中的树结构来实现的，树的每个结点都是一个inode结构体。设备注册和文件系统挂载后会根据路径在树中生成相应的结点。VFS最主要是两个功能：
-
--   查找节点。
--   统一调用（标准）。
-
-## 运作机制<a name="section18114182834215"></a>
-
-通过VFS层，可以使用标准的Unix文件操作函数（如open、read、write等）来实现对不同介质上不同文件系统的访问。
-
-VFS框架内存中的inode树结点有三种类型：
-
--   虚拟结点：作为VFS框架的虚拟文件，保持树的连续性，如/usr、/usr/bin。
--   设备结点：/dev目录下，对应一个设备，如/dev/mmcblk0。
--   挂载点：挂载具体文件系统，如/vs/sd、/mnt。
-
-**图 2**  文件系统树形结构<a name="fig1648112392612"></a>  
-![](figures/文件系统树形结构.png "文件系统树形结构")
-
-## 注意事项<a name="section18311145173712"></a>
-
--   VFS下的所有文件系统，创建的目录名和文件名最多只可以有255个字节，能支持的全路径长度最长为259字节，超过这个路径长度的文件和目录无法创建。
-
--   目前仅有jffs2文件系统支持完整的权限控制。
-
--   inode\_find\(\)函数调用后会使查找到的inode节点连接数+1，调用完成后需要调用inode\_release\(\)使连接数-1，所以一般inode\_find\(\)要和inode\_release\(\)配套使用。
-
--   设备分为字符设备和块设备，为了块设备上的文件系统系统数据安全，需挂载相应文件系统后通过文件系统接口操作数据。
-
--   los\_vfs\_init\(\)只能调用一次，多次调用将会造成文件系统异常。
-
--   目前OpenHarmony内核所有的文件系统中的文件名和目录名中只可以出现“-” 与“\_”两种特殊字符，使用其他特殊字符可能造成的后果不可预知，请谨慎为之。
-
--   OpenHarmony内核支持open\(\)+O\_DIRECTORY的方法获取目录数据信息。
-
--   挂载点必须为空目录，不能重复挂载至同一挂载点或挂载至其他挂载点下的目录或文件，错误挂载可能损坏设备及系统。
-
--   open打开一个文件时，参数O\_RDWR、O\_WRONLY、O\_RDONLY互斥，只能出现一个，若出现2个或以上作为open的参数，文件读写操作会被拒绝，并返回EACCESS错误码，禁止使用。
-
--   OpenHarmony内核文件系统在umount操作之前，需确保所有目录及文件全部关闭，否则umount会失败。如果强制umount，可能导致包括但不限于文件系统损坏、设备损坏等问题。
-
--   SD卡移除前，需确保所有目录及文件全部关闭，并进行umount操作。如果强制拔卡，可能导致包括但不限于SD数据丢失、SD卡损坏等问题。
-
-
-## 开发指导<a name="section422619258380"></a>
-
-**开发流程**
-
-推荐驱动开发人员使用VFS框架来注册/卸载设备，即调用register\_driver\(\)、register\_blockdriver\(\)接口生成设备结点，应用层使用open\(\)、read\(\)操作设备（字符设备）文件来调用驱动。
-
-**文件描述符**
-
-本系统中，进程的文件描述符最多有256个（File和Socket描述符合并统计），系统文件描述符共640个，系统文件描述符规格：
-
--   File描述符，普通文件描述符，系统总规格为512。
-
--   Socket描述符，系统总规格为128。
-
-
-**VFS支持的操作**
-
-open, close, read, write, seek, ioctl, fcntl, mmap, sync, dup, dup2, truncate, opendir, closedir, readdir,  rewinddir, mount, umount, statfs, unlink, remove, mkdir, rmdir, rename, stat, utime, seek64, fallocate, fallocate64, truncate64, chmod, chown。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   当前只提供修改jffs2文件以及vfs设备节点属性的接口，各个系统对只读等属性有各自的处理方式。
->-   在OpenHarmony内核中属性并不冲突（可以任意修改）。
->-   在OpenHarmony内核中只读属性文件/目录不允许被删除。
->-   在OpenHarmony内核中只读属性文件/目录允许rename。
->-   只读文件不允许以O\_CREAT、O\_TRUNC，以及有含有写的权限的方式打开。
->-   在OpenHarmony内核中设置的系统文件加上隐藏属性，在Windows中只能通过命令行找到（在显示，不显示隐藏文件的属性情况下都不能看到）。

-在以太网中，主机之间的通信是直接使用MAC地址（非IP地址）来通信的，所以，对于使用IP通信的协议，必须能够将IP地址转换成MAC地址，才能在局域网（以太网）内通信。解决这个问题的方法就是主机存储一张IP和MAC地址对应的表，即ARP缓存，主机要往一个局域网内的目的IP地址发送IP包时，就可以从ARP缓存表中查询到目的MAC地址。ARP缓存是由TCP/IP协议栈维护的，用户可通过ARP命令查看和修改ARP表。

--   同一路径下，源文件与目的文件不能重名。
--   源文件必须存在，且不为目录。
--   源文件路径支持“\*”和“？”通配符，“\*”代表任意多个字符，“？”代表任意单个字符。目的路径不支持通配符。当源路径可匹配多个文件时，目的路径必须为目录。
--   目的路径为目录时，该目录必须存在。此时目的文件以源文件命名。
--   目的路径为文件时，所在目录必须存在。此时拷贝文件的同时为副本重命名。
--   目前不支持多文件拷贝。参数大于2个时，只对前2个参数进行操作。
--   目的文件不存在时创建新文件，已存在则覆盖。

--   该命令依赖于LOSCFG\_SHELL\_DMESG，使用时通过menuconfig在配置项中开启"Enable Shell dmesg"：
-
-    Debug  ---\> Enable a Debug Version ---\> Enable Shell ---\> Enable Shell dmesg
-
--   dmesg参数缺省时，默认打印缓存区内容。
--   各“ - ”选项不能混合使用。
-    1.  写入文件需确保已挂载文件系统。
-    2.  关闭串口打印会影响shell使用，建议先连接telnet再尝试关闭串口。

+## 基本概念<a name="section1990715203418"></a>
+
+双向链表是指含有往前和往后两个方向的链表，即每个结点中除存放下一个节点指针外，还增加一个指向前一个节点的指针。其头指针head是唯一确定的。
+
+从双向链表中的任意一个结点开始，都可以很方便地访问它的前驱结点和后继结点，这种数据结构形式使得双向链表在查找时更加方便，特别是大量数据的遍历。由于双向链表具有对称性，能方便地完成各种插入、删除等操作，但需要注意前后方向的操作。
+
+## 功能说明<a name="section848334511411"></a>
+
+双向链表模块为用户提供下面几种功能，接口详细信息可以查看API参考。

+## 开发流程<a name="section01781261552"></a>
+
+双向链表的典型开发流程：
+
+1.  调用LOS\_ListInit/LOS\_DL\_LIST\_HEAD初始双向链表。
+2.  调用LOS\_ListAdd向链表插入节点。
+3.  调用LOS\_ListTailInsert向链表尾部插入节点。
+4.  调用LOS\_ListDelete删除指定节点。
+5.  调用LOS\_ListEmpty判断链表是否为空。
+6.  调用LOS\_ListDelInit删除指定节点并以此节点初始化链表。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   需要注意节点指针前后方向的操作。
+>-   链表操作接口，为底层接口，不对入参进行判空，需要使用者确保传参合法。
+>-   如果链表节点的内存是动态申请的，删除节点时，要注意释放内存。
+
+## 编程实例<a name="section67569495514"></a>
+
+### 实例描述<a name="section48761994551"></a>
+
+本实例实现如下功能：
+
+1.  初始化双向链表。
+2.  增加节点。
+3.  删除节点。
+4.  测试操作是否成功。
+
+### 示例代码<a name="section1280202685519"></a>
+
+示例代码如下:
+
+```
+#include "stdio.h"
+#include "los_list.h"
+
+static UINT32 ListSample(VOID)
+{
+    LOS_DL_LIST listHead = {NULL,NULL};
+    LOS_DL_LIST listNode1 = {NULL,NULL};
+    LOS_DL_LIST listNode2 = {NULL,NULL};
+
+    //首先初始化链表
+    printf("Initial head\n");
+    LOS_ListInit(&listHead);
+
+    //添加节点1和节点2，并校验他们的相互关系
+    LOS_ListAdd(&listHead, &listNode1);
+    if (listNode1.pstNext == &listHead && listNode1.pstPrev == &listHead) {
+        printf("Add listNode1 success\n");
+    }
+
+    LOS_ListTailInsert(&listHead, &listNode2);
+    if (listNode2.pstNext == &listHead && listNode2.pstPrev == &listNode1) {
+        printf("Tail insert listNode2 success\n");
+    }
+
+    //删除两个节点
+    LOS_ListDelete(&listNode1);
+    LOS_ListDelete(&listNode2);
+
+    //确认链表为空
+    if (LOS_ListEmpty(&listHead)) {
+        printf("Delete success\n");
+    }
+
+    return LOS_OK;
+}
+```
+
+### 结果验证<a name="section5811249105512"></a>
+
+编译运行得到的结果为：
+
+```
+Initial head 
+Add listNode1 success 
+Tail insert listNode2 success
+Delete success 
+```

+## 基本概念<a name="section131091144111615"></a>
+
+[CMSIS](https://developer.arm.com/tools-and-software/embedded/cmsis)是Cortex Microcontroller Software Interface Standard（Cortex微控制器软件接口标准）的缩写，是对于那些基于ARM Cortex处理器的微控制器独立于供应商的硬件抽象层。它包含多个组件层，其中之一是RTOS层，该层定义了一套通用及标准化的RTOS API接口，减少了应用开发者对特定RTOS的依赖，方便用户软件的移植重用。该套API有2个版本，分别为版本1（CMSIS-RTOS v1）和版本2（CMSIS-RTOS v2），OpenHarmony LiteOS-M仅提供其版本2的实现。

+
+CMSIS-RTOS2组件可以作为库或源代码提供（下图显示了库）。通过添加CMSIS-RTOS2组件（通常是一些配置文件），可以将基于CMSIS的应用程序扩展为具有RTOS功能。只需包含cmsis\_os2.h头文件就可以访问RTOS API函数，这使用户应用程序能够处理RTOS内核相关事件，而在更换内核时无需重新编译源代码。
+
+静态对象分配需要访问RTOS对象控制块定义。特定于实现的头文件（下图中的os\_xx .h）提供对此类控制块定义的访问。对于OpenHarmony LiteOS-M内核，由文件名以los\_开头的头文件提供，这些文件包含OpenHarmony LiteOS-M内核的这些定义。

+
+1.  调用中断创建接口HalHwiCreate创建中断。
+2.  调用TestHwiTrigger接口触发指定中断（该接口在测试套中定义，通过写中断控制器的相关寄存器模拟外部中断，一般的外设设备，不需要执行这一步）。
+3.  调用HalHwiDelete接口删除指定中断，此接口根据实际情况使用，判断是否需要删除中断。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   根据具体硬件，配置支持的最大中断数及可设置的中断优先级个数。
+>-   中断处理程序耗时不能过长，否则会影响CPU对中断的及时响应。
+>-   中断响应过程中不能直接、间接执行引起调度的LOS\_Schedule等函数。
+>-   中断恢复LOS\_IntRestore\(\)的入参必须是与之对应的LOS\_IntLock\(\)的返回值（即关中断之前的CPSR值）。Cortex-M系列处理器中0-15中断为内部使用，因此不建议用户去申请和创建。
+
+## 编程实例<a name="section460018317164"></a>
+
+本实例实现如下功能：
+
+1.  创建中断。
+2.  触发中断。
+3.  删除中断。
+
+代码实现如下，演示如何创建中断和删除中断，当指定的中断号HWI\_NUM\_TEST产生中断时，会调用中断处理函数：
+
+```
+#include "los_interrupt.h"
+
+/*创建中断*/
+#define HWI_NUM_TEST 7
+
+STATIC VOID HwiUsrIrq(VOID)
+{
+    printf("in the func HwiUsrIrq \n"); 
+}
+
+static UINT32 Example_Interrupt(VOID)
+{
+    UINT32 ret;
+    HWI_PRIOR_T hwiPrio = 3;
+    HWI_MODE_T mode = 0;
+    HWI_ARG_T arg = 0;
+  
+    /*创建中断*/
+    ret = HalHwiCreate(HWI_NUM_TEST, hwiPrio, mode, (HWI_PROC_FUNC)HwiUsrIrq, arg);
+    if(ret == LOS_OK){
+        printf("Hwi create success!\n");
+    } else {
+        printf("Hwi create failed!\n");
+        return LOS_NOK;
+    }
+
+    /* 延时50个Ticks， 当有硬件中断发生时，会调用函数HwiUsrIrq*/
+    LOS_TaskDelay(50);
+
+    /*删除中断*/
+    ret = HalHwiDelete(HWI_NUM_TEST);    
+    if(ret == LOS_OK){
+        printf("Hwi delete success!\n");
+    } else {
+        printf("Hwi delete failed!\n");
+        return LOS_NOK;
+    }
+    return LOS_OK;
+}
+```
+
+### 结果验证<a name="section1048572415182"></a>
+
+编译运行得到的结果为：
+
+```
+Hwi create success!
+Hwi delete success!.
+```

+
+事件的典型开发流程：
+
+1.  初始化事件控制块
+2.  阻塞读事件控制块
+3.  写入相关事件
+4.  阻塞任务被唤醒，读取事件并检查是否满足要求
+5.  处理事件控制块
+6.  事件控制块销毁
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   进行事件读写操作时，事件的第25位为保留位，不可以进行位设置。
+>-   对同一事件反复写入，算作一次写入。
+
+## 编程实例<a name="section460018317164"></a>
+
+### 实例描述<a name="section896412438910"></a>
+
+示例中，任务Example\_TaskEntry创建一个任务Example\_Event，Example\_Event读事件阻塞，Example\_TaskEntry向该任务写事件。可以通过示例日志中打印的先后顺序理解事件操作时伴随的任务切换。
+
+1.  在任务Example\_TaskEntry创建任务Example\_Event，其中任务Example\_Event优先级高于Example\_TaskEntry。
+2.  在任务Example\_Event中读事件0x00000001，阻塞，发生任务切换，执行任务Example\_TaskEntry。
+3.  在任务Example\_TaskEntry向任务Example\_Event写事件0x00000001，发生任务切换，执行任务Example\_Event。
+4.  Example\_Event得以执行，直到任务结束。
+5.  Example\_TaskEntry得以执行，直到任务结束。

+事件（Event）是一种任务间的通信机制，可用于任务间的同步操作。事件的特点是：
+
+-   任务间的事件同步，可以一对多，也可以多对多。一对多表示一个任务可以等待多个事件，多对多表示多个任务可以等待多个事件。但是一次写事件最多触发一个任务从阻塞中醒来。
+-   事件读超时机制。
+-   只做任务间同步，不传输具体数据。
+
+提供了事件初始化、事件读写、事件清零、事件销毁等接口。
+
+## 运行机制<a name="section1735611583011"></a>
+
+### 事件控制块<a name="section1161415384467"></a>
+
+```
+/**
+  * 事件控制块数据结构
+  */
+typedef struct tagEvent {
+    UINT32 uwEventID;        /* 事件集合，表示已经处理（写入和清零）的事件集合 */
+    LOS_DL_LIST stEventList; /* 等待特定事件的任务链表 */
+} EVENT_CB_S, *PEVENT_CB_S;
+```
+
+### 事件运作原理<a name="section187761153144617"></a>
+
+**事件初始化：**会创建一个事件控制块，该控制块维护一个已处理的事件集合，以及等待特定事件的任务链表。
+
+**写事件：**会向事件控制块写入指定的事件，事件控制块更新事件集合，并遍历任务链表，根据任务等待具体条件满足情况决定是否唤醒相关任务。
+
+**读事件：**如果读取的事件已存在时，会直接同步返回。其他情况会根据超时时间以及事件触发情况，来决定返回时机：等待的事件条件在超时时间耗尽之前到达，阻塞任务会被直接唤醒，否则超时时间耗尽该任务才会被唤醒。
+
+读事件条件满足与否取决于入参eventMask和mode，eventMask即需要关注的事件。mode是具体处理方式，分以下三种情况：
+
+LOS\_WAITMODE\_AND：表示eventMask中所有事件都发生时，才返回。
+
+LOS\_WAITMODE\_OR：表示eventMask中任何事件发生时，就返回。
+
+LOS\_WAITMODE\_CLR：事件读取成功后，对应读取到的事件会被清零。需要配合LOS\_WAITMODE\_AND或者LOS\_WAITMODE\_OR来使用。
+
+**事件清零：**根据指定掩码，去对事件控制块的事件集合进行清零操作。当掩码为0时，表示将事件集合全部清零。当掩码为0xffff时，表示不清除任何事件，保持事件集合原状。
+
+**事件销毁：**销毁指定的事件控制块。

+
+互斥锁又称互斥型信号量，是一种特殊的二值性信号量，用于实现对共享资源的独占式处理。
+
+任意时刻互斥锁的状态只有两种，开锁或闭锁。当有任务持有时，互斥锁处于闭锁状态，这个任务获得该互斥锁的所有权。当该任务释放它时，该互斥锁被开锁，任务失去该互斥锁的所有权。当一个任务持有互斥锁时，其他任务将不能再对该互斥锁进行开锁或持有。
+
+多任务环境下往往存在多个任务竞争同一共享资源的应用场景，互斥锁可被用于对共享资源的保护从而实现独占式访问。另外互斥锁可以解决信号量存在的优先级翻转问题。
+
+## 运行机制<a name="section115161649726"></a>
+
+多任务环境下会存在多个任务访问同一公共资源的场景，而有些公共资源是非共享的，需要任务进行独占式处理。互斥锁怎样来避免这种冲突呢？
+
+用互斥锁处理非共享资源的同步访问时，如果有任务访问该资源，则互斥锁为加锁状态。此时其他任务如果想访问这个公共资源则会被阻塞，直到互斥锁被持有该锁的任务释放后，其他任务才能重新访问该公共资源，此时互斥锁再次上锁，如此确保同一时刻只有一个任务正在访问这个公共资源，保证了公共资源操作的完整性。

+## 开发流程<a name="section783435801510"></a>
+
+互斥锁典型场景的开发流程：
+
+1.  创建互斥锁LOS\_MuxCreate。
+2.  申请互斥锁LOS\_MuxPend。
+
+    申请模式有三种：无阻塞模式、永久阻塞模式、定时阻塞模式。
+
+    -   无阻塞模式：任务需要申请互斥锁，若该互斥锁当前没有任务持有，或者持有该互斥锁的任务和申请该互斥锁的任务为同一个任务，则申请成功。
+    -   永久阻塞模式：任务需要申请互斥锁，若该互斥锁当前没有被占用，则申请成功。否则，该任务进入阻塞态，系统切换到就绪任务中优先级高者继续执行。任务进入阻塞态后，直到有其他任务释放该互斥锁，阻塞任务才会重新得以执行。
+    -   定时阻塞模式：任务需要申请互斥锁，若该互斥锁当前没有被占用，则申请成功。否则该任务进入阻塞态，系统切换到就绪任务中优先级高者继续执行。任务进入阻塞态后，指定时间超时前有其他任务释放该互斥锁，或者用户指定时间超时后，阻塞任务才会重新得以执行。
+
+3.  释放互斥锁LOS\_MuxPost。
+    -   如果有任务阻塞于指定互斥锁，则唤醒被阻塞任务中优先级高的，该任务进入就绪态，并进行任务调度；
+    -   如果没有任务阻塞于指定互斥锁，则互斥锁释放成功。
+
+4.  删除互斥锁LOS\_MuxDelete。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   两个任务不能对同一把互斥锁加锁。如果某任务对已被持有的互斥锁加锁，则该任务会被挂起，直到持有该锁的任务对互斥锁解锁，才能执行对这把互斥锁的加锁操作。
+>-   互斥锁不能在中断服务程序中使用。
+>-   LiteOS-M内核作为实时操作系统需要保证任务调度的实时性，尽量避免任务的长时间阻塞，因此在获得互斥锁之后，应该尽快释放互斥锁。
+>-   持有互斥锁的过程中，不得再调用LOS\_TaskPriSet等接口更改持有互斥锁任务的优先级。
+
+## 编程实例<a name="section1426719434114"></a>
+
+### 实例描述<a name="section896412438910"></a>
+
+本实例实现如下流程。
+
+1.  任务Example\_TaskEntry创建一个互斥锁，锁任务调度，创建两个任务Example\_MutexTask1、Example\_MutexTask2。Example\_MutexTask2优先级高于Example\_MutexTask1，解锁任务调度。
+2.  Example\_MutexTask2被调度，以永久阻塞模式申请互斥锁，并成功获取到该互斥锁，然后任务休眠100Tick，Example\_MutexTask2挂起，Example\_MutexTask1被唤醒。
+3.  Example\_MutexTask1以定时阻塞模式申请互斥锁，等待时间为10Tick，因互斥锁仍被Example\_MutexTask2持有，Example\_MutexTask1挂起。10Tick超时时间到达后，Example\_MutexTask1被唤醒，以永久阻塞模式申请互斥锁，因互斥锁仍被Example\_MutexTask2持有，Example\_MutexTask1挂起。
+4.  100Tick休眠时间到达后，Example\_MutexTask2被唤醒， 释放互斥锁，唤醒Example\_MutexTask1。Example\_MutexTask1成功获取到互斥锁后，释放，删除互斥锁。

+
+
+队列又称消息队列，是一种常用于任务间通信的数据结构。队列接收来自任务或中断的不固定长度消息，并根据不同的接口确定传递的消息是否存放在队列空间中。
+
+任务能够从队列里面读取消息，当队列中的消息为空时，挂起读取任务；当队列中有新消息时，挂起的读取任务被唤醒并处理新消息。任务也能够往队列里写入消息，当队列已经写满消息时，挂起写入任务；当队列中有空闲消息节点时，挂起的写入任务被唤醒并写入消息。
+
+可以通过调整读队列和写队列的超时时间来调整读写接口的阻塞模式，如果将读队列和写队列的超时时间设置为0，就不会挂起任务，接口会直接返回，这就是非阻塞模式。反之，如果将都队列和写队列的超时时间设置为大于0的时间，就会以阻塞模式运行。
+
+消息队列提供了异步处理机制，允许将一个消息放入队列，但不立即处理。同时队列还有缓冲消息的作用，可以使用队列实现任务异步通信，队列具有如下特性：
+
+-   消息以先进先出的方式排队，支持异步读写。
+-   读队列和写队列都支持超时机制。
+-   每读取一条消息，就会将该消息节点设置为空闲。
+-   发送消息类型由通信双方约定，可以允许不同长度（不超过队列的消息节点大小）的消息。
+-   一个任务能够从任意一个消息队列接收和发送消息。
+-   多个任务能够从同一个消息队列接收和发送消息。
+-   创建队列时所需的队列空间，接口内系统自行动态申请内存。

+    LOS_DL_LIST memList;                         /* 内存块链表 */

+```
+
+每个队列控制块中都含有队列状态，表示该队列的使用情况：
+
+-   OS\_QUEUE\_UNUSED：队列未被使用。
+-   OS\_QUEUE\_INUSED：队列被使用中。
+
+### 队列运作原理<a name="section15384012164811"></a>
+
+-   创建队列时，创建队列成功会返回队列ID。
+-   在队列控制块中维护着一个消息头节点位置Head和一个消息尾节点位置Tail，用于表示当前队列中消息的存储情况。Head表示队列中被占用的消息节点的起始位置。Tail表示被占用的消息节点的结束位置，也是空闲消息节点的起始位置。队列刚创建时，Head和Tail均指向队列起始位置。
+-   写队列时，根据readWriteableCnt\[1\]判断队列是否可以写入，不能对已满（readWriteableCnt\[1\]为0）队列进行写操作。写队列支持两种写入方式：向队列尾节点写入，也可以向队列头节点写入。尾节点写入时，根据Tail找到起始空闲消息节点作为数据写入对象，如果Tail已经指向队列尾部则采用回卷方式。头节点写入时，将Head的前一个节点作为数据写入对象，如果Head指向队列起始位置则采用回卷方式。
+-   读队列时，根据readWriteableCnt\[0\]判断队列是否有消息需要读取，对全部空闲（readWriteableCnt\[0\]为0）队列进行读操作会引起任务挂起。如果队列可以读取消息，则根据Head找到最先写入队列的消息节点进行读取。如果Head已经指向队列尾部则采用回卷方式。
+-   删除队列时，根据队列ID找到对应队列，把队列状态置为未使用，把队列控制块置为初始状态，并释放队列所占内存。

+
+1.  用LOS\_QueueCreate创建队列。创建成功后，可以得到队列ID。
+2.  通过LOS\_QueueWrite或者LOS\_QueueWriteCopy写队列。
+3.  通过LOS\_QueueRead或者LOS\_QueueReadCopy读队列。
+4.  通过LOS\_QueueInfoGet获取队列信息。
+5.  通过LOS\_QueueDelete删除队列。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   系统支持的最大队列数是指：整个系统的队列资源总个数，而非用户能使用的个数。例如：系统软件定时器多占用一个队列资源，那么用户能使用的队列资源就会减少一个。
+>-   创建队列时传入的队列名和flags暂时未使用，作为以后的预留参数。
+>-   队列接口函数中的入参timeOut是相对时间。
+>-   LOS\_QueueReadCopy和LOS\_QueueWriteCopy及LOS\_QueueWriteHeadCopy是一组接口，LOS\_QueueRead和LOS\_QueueWrite及LOS\_QueueWriteHead是一组接口，每组接口需要配套使用。
+>-   鉴于LOS\_QueueWrite和LOS\_QueueWriteHead和LOS\_QueueRead这组接口实际操作的是数据地址，用户必须保证调用LOS\_QueueRead获取到的指针所指向的内存区域在读队列期间没有被异常修改或释放，否则可能导致不可预知的后果。
+>-   鉴于LOS\_QueueWrite和LOS\_QueueWriteHead和LOS\_QueueRead这组接口实际操作的是数据地址，也就意味着实际写和读的消息长度仅仅是一个指针数据，因此用户使用这组接口之前，需确保创建队列时的消息节点大小，为一个指针的长度，避免不必要的浪费和读取失败。

+    -   [信号量运作原理](#section139726510491)
+
+
+信号量（Semaphore）是一种实现任务间通信的机制，可以实现任务间同步或共享资源的互斥访问。
+
+一个信号量的数据结构中，通常有一个计数值，用于对有效资源数的计数，表示剩下的可被使用的共享资源数，其值的含义分两种情况：
+
+-   0，表示该信号量当前不可获取，因此可能存在正在等待该信号量的任务。
+-   正值，表示该信号量当前可被获取。
+
+以同步为目的的信号量和以互斥为目的的信号量在使用上有如下不同：
+
+-   用作互斥时，初始信号量计数值不为0，表示可用的共享资源个数。在需要使用共享资源前，先获取信号量，然后使用一个共享资源，使用完毕后释放信号量。这样在共享资源被取完，即信号量计数减至0时，其他需要获取信号量的任务将被阻塞，从而保证了共享资源的互斥访问。另外，当共享资源数为1时，建议使用二值信号量，一种类似于互斥锁的机制。
+-   用作同步时，初始信号量计数值为0。任务1获取信号量而阻塞，直到任务2或者某中断释放信号量，任务1才得以进入Ready或Running态，从而达到了任务间的同步。
+
+## 运行机制<a name="section1794010261861"></a>
+
+### 信号量控制块<a name="section11372149164815"></a>
+
+```
+/**
+ * 信号量控制块数据结构
+ */
+typedef struct {
+    UINT16            semStat;          /* 信号量状态 */
+    UINT16            semType;          /* 信号量类型 */
+    UINT16            semCount;         /* 信号量计数 */
+    UINT16            semId;            /* 信号量索引号 */
+    LOS_DL_LIST       semList;          /* 挂接阻塞于该信号量的任务 */
+} LosSemCB;
+```
+
+### 信号量运作原理<a name="section139726510491"></a>
+
+信号量初始化，为配置的N个信号量申请内存（N值可以由用户自行配置，通过LOSCFG\_BASE\_IPC\_SEM\_LIMIT宏实现），并把所有信号量初始化成未使用，加入到未使用链表中供系统使用。
+
+信号量创建，从未使用的信号量链表中获取一个信号量，并设定初值。
+
+信号量申请，若其计数器值大于0，则直接减1返回成功。否则任务阻塞，等待其它任务释放该信号量，等待的超时时间可设定。当任务被一个信号量阻塞时，将该任务挂到信号量等待任务队列的队尾。
+

+## 编程实例<a name="section460018317164"></a>
+
+### 实例描述<a name="section22061718111412"></a>
+
+本实例实现如下功能：
+
+1.  测试任务ExampleSem创建一个信号量，锁任务调度，创建两个任务ExampleSemTask1、ExampleSemTask2, ExampleSemTask2优先级高于ExampleSemTask1，两个任务中申请同一信号量，解锁任务调度后两任务阻塞，测试任务ExampleSem释放信号量。
+2.  ExampleSemTask2得到信号量，被调度，然后任务休眠20Tick，ExampleSemTask2延迟，ExampleSemTask1被唤醒。
+3.  ExampleSemTask1定时阻塞模式申请信号量，等待时间为10Tick，因信号量仍被ExampleSemTask2持有，ExampleSemTask1挂起，10Tick后仍未得到信号量，ExampleSemTask1被唤醒，试图以永久阻塞模式申请信号量，ExampleSemTask1挂起。
+4.  20Tick后ExampleSemTask2唤醒， 释放信号量后，ExampleSemTask1得到信号量被调度运行，最后释放信号量。
+5.  ExampleSemTask1执行完，40Tick后任务ExampleSem被唤醒，执行删除信号量。

+## 运行机制<a name="section328282013571"></a>
+
+动态内存管理，即在内存资源充足的情况下，根据用户需求，从系统配置的一块比较大的连续内存（内存池，也是堆内存）中分配任意大小的内存块。当用户不需要该内存块时，又可以释放回系统供下一次使用。与静态内存相比，动态内存管理的优点是按需分配，缺点是内存池中容易出现碎片。
+
+OpenHarmony LiteOS-M动态内存在TLSF算法的基础上，对区间的划分进行了优化，获得更优的性能，降低了碎片率。动态内存核心算法框图如下：
+
+**图 1**  动态内存核心算法<a name="fig14558185217397"></a>  
+![](figure/动态内存核心算法.png "动态内存核心算法")
+
+根据空闲内存块的大小，使用多个空闲链表来管理。根据内存空闲块大小分为两个部分：\[4, 127\]和\[2<sup>7</sup>, 2<sup>31</sup>\]，如上图size class所示：
+
+1.  对\[4,127\]区间的内存进行等分，如上图绿色部分所示，分为31个小区间，每个小区间对应内存块大小为4字节的倍数。每个小区间对应一个空闲内存链表和用于标记对应空闲内存链表是否为空的一个比特位，值为1时，空闲链表非空。\[4,127\]区间的31个小区间内存对应31个比特位进行标记链表是否为空。
+2.  大于127字节的空闲内存块，按照2的次幂区间大小进行空闲链表管理。总共分为24个小区间，每个小区间又等分为8个二级小区间，见上图蓝色的Size Class和Size SubClass部分。每个二级小区间对应一个空闲链表和用于标记对应空闲内存链表是否为空的一个比特位。总共24\*8=192个二级小区间，对应192个空闲链表和192个比特位进行标记链表是否为空。
+
+例如，当有40字节的空闲内存需要插入空闲链表时，对应小区间\[40,43\]，第10个空闲链表，位图标记的第10比特位。把40字节的空闲内存挂载第10个空闲链表上，并判断是否需要更新位图标记。当需要申请40字节的内存时，根据位图标记获取存在满足申请大小的内存块的空闲链表，从空闲链表上获取空闲内存节点。如果分配的节点大于需要申请的内存大小，进行分割节点操作，剩余的节点重新挂载到相应的空闲链表上。当有580字节的空闲内存需要插入空闲链表时，对应二级小区间\[2^9,2^9+2^6\]，第31+2\*8=47个空闲链表，并使用位图的第47个比特位来标记链表是否为空。把580字节的空闲内存挂载第47个空闲链表上，并判断是否需要更新位图标记。当需要申请580字节的内存时，根据位图标记获取存在满足申请大小的内存块的空闲链表，从空闲链表上获取空闲内存节点。如果分配的节点大于需要申请的内存大小，进行分割节点操作，剩余的节点重新挂载到相应的空闲链表上。如果对应的空闲链表为空，则向更大的内存区间去查询是否有满足条件的空闲链表，实际计算时，会一次性查找到满足申请大小的空闲链表。
+
+内存管理结构如下图所示：
+
+**图 2**  动态内存管理结构图<a name="fig5395115964114"></a>  
+![](figure/动态内存管理结构图.png "动态内存管理结构图")
+
+-   内存池池头部分
+
+    内存池池头部分包含内存池信息、位图标记数组和空闲链表数组。内存池信息包含内存池起始地址及堆区域总大小，内存池属性。位图标记数组有7个32位无符号整数组成，每个比特位标记对应的空闲链表是否挂载空闲内存块节点。空闲内存链表包含223个空闲内存头节点信息，每个空闲内存头节点信息维护内存节点头和空闲链表中的前驱、后继空闲内存节点。
+
+-   内存池节点部分
+
+    包含3种类型节点：未使用空闲内存节点，已使用内存节点和尾节点。每个内存节点维护一个前序指针，指向内存池中上一个内存节点，还维护内存节点的大小和使用标记。空闲内存节点和已使用内存节点后面的内存区域是数据域，尾节点没有数据域。
+
+
+## 开发指导<a name="section7921151015814"></a>
+
+### 使用场景<a name="section326917198583"></a>
+
+动态内存管理的主要工作是动态分配并管理用户申请到的内存区间。动态内存管理主要用于用户需要使用大小不等的内存块的场景，当用户需要使用内存时，可以通过操作系统的动态内存申请函数索取指定大小的内存块，一旦使用完毕，通过动态内存释放函数归还所占用内存，使之可以重复使用。
+
+### 接口说明<a name="section1032331584"></a>

+>-   由于动态内存管理需要管理控制块数据结构来管理内存，这些数据结构会额外消耗内存，故实际用户可使用内存总量小于配置项OS\_SYS\_MEM\_SIZE的大小。
+>-   对齐分配内存接口LOS\_MemAllocAlign/LOS\_MemMallocAlign因为要进行地址对齐，可能会额外消耗部分内存，故存在一些遗失内存，当系统释放该对齐内存时，同时回收由于对齐导致的遗失内存。
+
+### 开发流程<a name="section07271773592"></a>
+
+本节介绍使用动态内存的典型场景开发流程。
+
+1.  初始化LOS\_MemInit。
+
+    初始一个内存池后生成一个内存池控制头、尾节点EndNode，剩余的内存被标记为FreeNode内存节点。注：EndNode作为内存池末尾的节点，size为0。
+
+
+1.  申请任意大小的动态内存LOS\_MemAlloc。
+
+    判断动态内存池中是否存在大于申请量大小的空闲内存块空间，若存在，则划出一块内存块，以指针形式返回，若不存在，返回NULL。如果空闲内存块大于申请量，需要对内存块进行分割，剩余的部分作为空闲内存块挂载到空闲内存链表上。
+
+
+1.  释放动态内存LOS\_MemFree。
+
+    回收内存块，供下一次使用。调用LOS\_MemFree释放内存块，则会回收内存块，并且将其标记为FreeNode。在回收内存块时，相邻的FreeNode会自动合并。
+
+
+### 编程实例<a name="section84931234145913"></a>
+
+本实例执行以下步骤：
+
+1.  初始化一个动态内存池。
+2.  从动态内存池中申请一个内存块。
+3.  在内存块中存放一个数据。
+4.  打印出内存块中的数据。
+5.  释放该内存块。
+
+示例代码如下：
+
+```
+#include "los_memory.h"
+
+VOID Example_DynMem(VOID)
+{
+    UINT32 *mem = NULL;
+    UINT32 ret;
+
+    /*初始化内存池*/
+    ret = LOS_MemInit(g_testPool, TEST_POOL_SIZE);
+    if (LOS_OK  == ret) {
+        printf("Mem init success!\n");
+    } else {
+        printf("Mem init failed!\n");
+        return;
+    }
+
+    /*分配内存*/
+    mem = (UINT32 *)LOS_MemAlloc(g_testPool, 4);
+    if (NULL == mem) {
+        printf("Mem alloc failed!\n");
+        return;
+    }
+    printf("Mem alloc success!\n");
+
+    /*赋值*/
+    *mem = 828;
+    printf("*mem = %d\n", *mem);
+
+    /*释放内存*/
+    ret = LOS_MemFree(g_testPool, mem);
+    if (LOS_OK == ret) {
+        printf("Mem free success!\n");
+    } else {
+        printf("Mem free failed!\n");
+    }
+
+    return;
+}
+```
+
+### 结果验证<a name="section165233233917"></a>
+
+输出结果如下：
+
+```
+Mem init success!
+Mem alloc success!
+*mem = 828
+Mem free success!
+```

+## 运行机制<a name="section165473517522"></a>
+
+静态内存实质上是一个静态数组，静态内存池内的块大小在初始化时设定，初始化后块大小不可变更。
+
+静态内存池由一个控制块LOS\_MEMBOX\_INFO和若干相同大小的内存块LOS\_MEMBOX\_NODE构成。控制块位于内存池头部，用于内存块管理，包含内存块大小uwBlkSize，内存块数量uwBlkNum，已分配使用的内存块数量uwBlkCnt和空闲内存块链表stFreeList。内存块的申请和释放以块大小为粒度，每个内存块包含指向下一个内存块的指针pstNext。

+## 开发指导<a name="section57511620165218"></a>
+
+### 使用场景<a name="section215474911529"></a>
+
+当用户需要使用固定长度的内存时，可以通过静态内存分配的方式获取内存，一旦使用完毕，通过静态内存释放函数归还所占用内存，使之可以重复使用。
+
+### 接口说明<a name="section79231214539"></a>

+
+1.  规划一片内存区域作为静态内存池。
+2.  调用LOS\_MemboxInit初始化静态内存池。
+
+    初始化会将入参指定的内存区域分割为N块（N值取决于静态内存总大小和块大小），将所有内存块挂到空闲链表，在内存起始处放置控制头。
+
+3.  调用LOS\_MemboxAlloc接口分配静态内存。
+
+    系统将会从空闲链表中获取第一个空闲块，并返回该内存块的起始地址。
+
+4.  调用LOS\_MemboxClr接口。
+
+    将入参地址对应的内存块清零。
+
+5.  调用LOS\_MemboxFree接口。
+
+    将该内存块加入空闲链表。

+### 编程实例<a name="section17801515105519"></a>
+
+本实例执行以下步骤：
+
+1.  初始化一个静态内存池。
+2.  从静态内存池中申请一块静态内存。
+3.  在内存块存放一个数据。
+4.  打印出内存块中的数据。
+5.  清除内存块中的数据。
+6.  释放该内存块。
+
+    示例代码如下：
+
+
+```
+#include "los_membox.h"
+
+VOID Example_StaticMem(VOID)
+{
+    UINT32 *mem = NULL;
+    UINT32 blkSize = 10;
+    UINT32 boxSize = 100;
+    UINT32 boxMem[1000];
+    UINT32 ret;
+
+    /*内存池初始化*/
+    ret = LOS_MemboxInit(&boxMem[0], boxSize, blkSize);
+    if(ret != LOS_OK) {
+        printf("Membox init failed!\n");
+        return;
+    } else {
+        printf("Membox init success!\n");
+    }
+
+    /*申请内存块*/
+    mem = (UINT32 *)LOS_MemboxAlloc(boxMem);
+    if (NULL == mem) {
+        printf("Mem alloc failed!\n");
+        return;
+    }
+    printf("Mem alloc success!\n");
+
+    /*赋值*/
+    *mem = 828;
+    printf("*mem = %d\n", *mem);
+
+    /*清除内存内容*/
+    LOS_MemboxClr(boxMem, mem);
+    printf("Mem clear success \n *mem = %d\n", *mem);
+
+    /*释放内存*/
+    ret = LOS_MemboxFree(boxMem, mem);
+    if (LOS_OK == ret) {
+        printf("Mem free success!\n");
+    } else {
+        printf("Mem free failed!\n");
+    }
+
+    return;
+}
+```
+
+### 结果验证<a name="section11818154112319"></a>
+
+输出结果如下：
+
+```
+Membox init success!
+Mem alloc success!
+*mem = 828
+Mem clear success   
+*mem = 0
+Mem free success!
+```

+
+软件定时器的典型开发流程：
+
+1.  配置软件定时器。
+    -   确认配置项LOSCFG\_BASE\_CORE\_SWTMR和LOSCFG\_BASE\_IPC\_QUEUE为1打开状态；
+    -   配置LOSCFG\_BASE\_CORE\_SWTMR\_LIMIT最大支持的软件定时器数；
+    -   配置OS\_SWTMR\_HANDLE\_QUEUE\_SIZE软件定时器队列最大长度；
+
+2.  创建定时器LOS\_SwtmrCreate。
+    -   创建一个指定计时时长、指定超时处理函数、指定触发模式的软件定时器；
+    -   返回函数运行结果，成功或失败；
+
+3.  启动定时器LOS\_SwtmrStart。
+4.  获得软件定时器剩余Tick数LOS\_SwtmrTimeGet。
+5.  停止定时器LOS\_SwtmrStop。
+6.  删除定时器LOS\_SwtmrDelete。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   软件定时器的回调函数中不要做过多操作，不要使用可能引起任务挂起或者阻塞的接口或操作。
+>-   软件定时器使用了系统的一个队列和一个任务资源，软件定时器任务的优先级设定为0，且不允许修改  。
+>-   系统可配置的软件定时器资源个数是指：整个系统可使用的软件定时器资源总个数，而并非是用户可使用的软件定时器资源个数。例如：系统软件定时器多占用一个软件定时器资源数，那么用户能使用的软件定时器资源就会减少一个。
+>-   创建单次软件定时器，该定时器超时执行完回调函数后，系统会自动删除该软件定时器，并回收资源。
+>-   创建单次不自删除属性的定时器，用户需要调用定时器删除接口删除定时器，回收定时器资源，避免资源泄露。

+-   [任务相关概念](#section673132352511)
+-   [任务运行机制](#section176294469251)
+
+从系统角度看，任务是竞争系统资源的最小运行单元。任务可以使用或等待CPU、使用内存空间等系统资源，并独立于其它任务运行。
+
+OpenHarmony LiteOS-M的任务模块可以给用户提供多个任务，实现任务间的切换，帮助用户管理业务程序流程。任务模块具有如下特性：
+
+-   支持多任务。
+-   一个任务表示一个线程。
+-   抢占式调度机制，高优先级的任务可打断低优先级任务，低优先级任务必须在高优先级任务阻塞或结束后才能得到调度。
+-   相同优先级任务支持时间片轮转调度方式。
+-   共有32个优先级\[0-31\]，最高优先级为0，最低优先级为31。
+
+## 任务相关概念<a name="section673132352511"></a>
+
+**任务状态**
+
+任务有多种运行状态。系统初始化完成后，创建的任务就可以在系统中竞争一定的资源，由内核进行调度。
+
+任务状态通常分为以下四种：
+
+-   就绪（Ready）：该任务在就绪队列中，只等待CPU。
+-   运行（Running）：该任务正在执行。
+-   阻塞（Blocked）：该任务不在就绪队列中。包含任务被挂起（suspend状态）、任务被延时（delay状态）、任务正在等待信号量、读写队列或者等待事件等。
+-   退出态（Dead）：该任务运行结束，等待系统回收资源。
+
+**任务状态迁移**
+
+**图 1**  任务状态示意图<a name="fig65504113015"></a>  
+![](figure/任务状态示意图.png "任务状态示意图")
+
+**任务状态迁移说明：**
+
+-   就绪态→运行态
+
+    任务创建后进入就绪态，发生任务切换时，就绪队列中最高优先级的任务被执行，从而进入运行态，同时该任务从就绪队列中移出。
+
+-   运行态→阻塞态
+
+    正在运行的任务发生阻塞（挂起、延时、读信号量等）时，该任务会从就绪队列中删除，任务状态由运行态变成阻塞态，然后发生任务切换，运行就绪队列中最高优先级任务。
+
+-   阻塞态→就绪态（阻塞态→运行态）
+
+    阻塞的任务被恢复后（任务恢复、延时时间超时、读信号量超时或读到信号量等），此时被恢复的任务会被加入就绪队列，从而由阻塞态变成就绪态；此时如果被恢复任务的优先级高于正在运行任务的优先级，则会发生任务切换，该任务由就绪态变成运行态。
+
+-   就绪态→阻塞态
+
+    任务也有可能在就绪态时被阻塞（挂起），此时任务状态由就绪态变为阻塞态，该任务从就绪队列中删除，不会参与任务调度，直到该任务被恢复。
+
+-   运行态→就绪态
+
+    有更高优先级任务创建或者恢复后，会发生任务调度，此刻就绪队列中最高优先级任务变为运行态，那么原先运行的任务由运行态变为就绪态，依然在就绪队列中。
+
+-   运行态→退出态
+
+    运行中的任务运行结束，任务状态由运行态变为退出态。退出态包含任务运行结束的正常退出状态以及Invalid状态。例如，任务运行结束但是没有自删除，对外呈现的就是Invalid状态，即退出态。
+
+-   阻塞态→退出态
+
+    阻塞的任务调用删除接口，任务状态由阻塞态变为退出态。
+
+
+**任务ID**
+
+任务ID，在任务创建时通过参数返回给用户，是任务的重要标识。系统中的ID号是唯一的。用户可以通过任务ID对指定任务进行任务挂起、任务恢复、查询任务名等操作。
+
+**任务优先级**
+
+优先级表示任务执行的优先顺序。任务的优先级决定了在发生任务切换时即将要执行的任务，就绪队列中最高优先级的任务将得到执行。
+
+**任务入口函数**
+
+新任务得到调度后将执行的函数。该函数由用户实现，在任务创建时，通过任务创建结构体设置。
+
+**任务栈**
+
+每个任务都拥有一个独立的栈空间，我们称为任务栈。栈空间里保存的信息包含局部变量、寄存器、函数参数、函数返回地址等。
+
+**任务上下文**
+
+任务在运行过程中使用的一些资源，如寄存器等，称为任务上下文。当这个任务挂起时，其他任务继续执行，可能会修改寄存器等资源中的值。如果任务切换时没有保存任务上下文，可能会导致任务恢复后出现未知错误。因此在任务切换时会将切出任务的任务上下文信息，保存在自身的任务栈中，以便任务恢复后，从栈空间中恢复挂起时的上下文信息，从而继续执行挂起时被打断的代码。
+
+**任务控制块TCB**
+
+每个任务都含有一个任务控制块\(TCB\)。TCB包含了任务上下文栈指针（stack pointer）、任务状态、任务优先级、任务ID、任务名、任务栈大小等信息。TCB可以反映出每个任务运行情况。
+
+**任务切换**
+
+任务切换包含获取就绪队列中最高优先级任务、切出任务上下文保存、切入任务上下文恢复等动作。
+
+## 任务运行机制<a name="section176294469251"></a>
+
+用户创建任务时，系统会初始化任务栈，预置上下文。此外，系统还会将“任务入口函数”地址放在相应位置。这样在任务第一次启动进入运行态时，将会执行“任务入口函数”。

+
+以创建任务为例，讲解开发流程。
+
+1.  锁任务调度LOS\_TaskLock，防止高优先级任务调度。
+2.  创建任务LOS\_TaskCreate。
+3.  解锁任务LOS\_TaskUnlock，让任务按照优先级进行调度。
+4.  延时任务LOS\_TaskDelay，任务延时等待。
+5.  挂起指定的任务LOS\_TaskSuspend，任务挂起等待恢复操作。
+6.  恢复挂起的任务LOS\_TaskResume。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   执行Idle任务时，会对待回收链表中的任务控制块和任务栈进行回收。
+>-   任务名是指针，并没有分配空间，在设置任务名时，禁止将局部变量的地址赋值给任务名指针。
+>-   任务栈的大小按8字节大小对齐。确定任务栈大小的原则是，够用就行，多了浪费，少了任务栈溢出。
+>-   挂起当前任务时，如果已经锁任务调度，则无法挂起。
+>-   Idle任务及软件定时器任务不能被挂起或者删除。
+>-   在中断处理函数中或者在锁任务的情况下，执行LOS\_TaskDelay会失败。
+>-   锁任务调度，并不关中断，因此任务仍可被中断打断。
+>-   锁任务调度必须和解锁任务调度配合使用。
+>-   设置任务优先级时可能会发生任务调度。
+>-   可配置的系统最大任务数是指：整个系统的任务总个数，而非用户能使用的任务个数。例如：系统软件定时器多占用一个任务资源，那么用户能使用的任务资源就会减少一个。
+>-   LOS\_CurTaskPriSet和LOS\_TaskPriSet接口不能在中断中使用，也不能用于修改软件定时器任务的优先级。
+>-   LOS\_TaskPriGet接口传入的task ID对应的任务未创建或者超过最大任务数，统一返回-1。
+>-   在删除任务时要保证任务申请的资源（如互斥锁、信号量等）已被释放。

+## 开发流程<a name="section783435801510"></a>
+
+时间管理的典型开发流程：
+
+1.  根据实际需求，完成板级配置适配，并配置系统主时钟频率OS\_SYS\_CLOCK（单位Hz）和LOSCFG\_BASE\_CORE\_TICK\_PER\_SECOND。OS\_SYS\_CLOCK的默认值基于硬件平台配置。
+2.  调用时钟转换/统计接口。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   时间管理不是单独的功能模块，依赖于OS\_SYS\_CLOCK和LOSCFG\_BASE\_CORE\_TICK\_PER\_SECOND两个配置选项。
+>-   系统的Tick数在关中断的情况下不进行计数，故系统Tick数不能作为准确时间使用。
+>-   配置选项维护在开发板工程的文件target\_config.h。
+
+## 编程实例<a name="section460018317164"></a>
+
+### 实例描述<a name="section127752801718"></a>
+
+在下面的例子中，介绍了时间管理的基本方法，包括：
+
+1.  时间转换：将毫秒数转换为Tick数，或将Tick数转换为毫秒数。
+2.  时间统计：每Tick的Cycle数、自系统启动以来的Tick数和延迟后的Tick数。
+
+### 示例代码<a name="section321653551711"></a>
+
+前提条件：
+
+-   使用每秒的Tick数LOSCFG\_BASE\_CORE\_TICK\_PER\_SECOND的默认值100。
+-   配好OS\_SYS\_CLOCK系统主时钟频率。
+
+时间转换：
+
+```
+VOID Example_TransformTime(VOID)
+{
+    UINT32 ms;
+    UINT32 tick;
+
+    tick = LOS_MS2Tick(10000);    // 10000ms转换为tick
+    dprintf("tick = %d \n", tick);
+    ms = LOS_Tick2MS(100);        // 100tick转换为ms
+    dprintf("ms = %d \n", ms);
+}
+```
+
+时间统计和时间延迟：
+
+```
+VOID Example_GetTime(VOID)
+{
+    UINT32 cyclePerTick;
+    UINT64 tickCount;
+
+    cyclePerTick  = LOS_CyclePerTickGet();
+    if(0 != cyclePerTick) {
+        dprintf("LOS_CyclePerTickGet = %d \n", cyclePerTick);
+    }
+
+    tickCount = LOS_TickCountGet();
+    if(0 != tickCount) {
+        dprintf("LOS_TickCountGet = %d \n", (UINT32)tickCount);
+    }
+
+    LOS_TaskDelay(200);
+    tickCount = LOS_TickCountGet();
+    if(0 != tickCount) {
+        dprintf("LOS_TickCountGet after delay = %d \n", (UINT32)tickCount);
+    }
+}
+```
+
+### 结果验证<a name="section4366193318167"></a>
+
+编译运行得到的结果为：
+
+时间转换：
+
+```
+tick = 1000
+ms = 1000
+```
+
+时间统计和时间延迟：
+
+```
+LOS_CyclePerTickGet = 495000 
+LOS_TickCountGet = 1 
+LOS_TickCountGet after delay = 201

+## 基本概念<a name="section1772629121418"></a>
+
+FAT文件系统是File Allocation Table（文件配置表）的简称，主要包括DBR区、FAT区、DATA区三个区域。其中，FAT区各个表项记录存储设备中对应簇的信息，包括簇是否被使用、文件下一个簇的编号、是否文件结尾等。FAT文件系统有FAT12、FAT16、FAT32等多种格式，其中，12、16、32表示对应格式中FAT表项的字节数。FAT文件系统支持多种介质，特别在可移动存储介质（U盘、SD卡、移动硬盘等）上广泛使用，使嵌入式设备和Windows、Linux等桌面系统保持很好的兼容性，方便用户管理操作文件。
+
+OpenHarmony内核支持FAT12、FAT16与FAT32三种格式的FAT文件系统，具有代码量小、资源占用小、可裁切、支持多种物理介质等特性，并且与Windows、Linux等系统保持兼容，支持多设备、多分区识别等功能。OpenHarmony内核支持硬盘多分区，可以在主分区以及逻辑分区上创建FAT文件系统。

+
+### 驱动适配<a name="section19174939191414"></a>
+
+FAT文件系统的使用需要底层MMC相关驱动的支持。在一个带MMC存储设备的板子上运行FATFS，需要：
+
+1、适配板端EMMC驱动，实现disk\_status、disk\_initialize、disk\_read、disk\_write、disk\_ioctl接口；
+
+2、新增fs\_config.h文件，配置FS\_MAX\_SS（存储设备最大sector大小）、FF\_VOLUME\_STRS（分区名）等信息，例如：
+
+```
+#define FF_VOLUME_STRS     "system", "inner", "update", "user"
+#define FS_MAX_SS          512
+#define FAT_MAX_OPEN_FILES 50
+```
+
+### 开发流程<a name="section131211626151513"></a>
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   FATFS文件与目录操作：
+>    -   单个文件大小不超过4G。
+>    -   支持同时打开的文件数最大为FAT\_MAX\_OPEN\_FILES，文件夹数最大为FAT\_MAX\_OPEN\_DIRS。
+>    -   暂不支持根目录管理，文件/目录名均以分区名开头，例如“user/testfile”就是在“user”分区下名为“testfile”的文件或目录。
+>    -   若需要同时多次打开同一文件，必须全部使用只读方式（O\_RDONLY）。以可写方式（O\_RDWR、O\_WRONLY等）只能打开一次。
+>    -   读写指针未分离，例如以O\_APPEND（追加写）方式打开文件后，读指针也在文件尾，从头读文件前需要用户手动置位。
+>    -   暂不支持文件与目录的权限管理。
+>    -   stat及fstat接口暂不支持查询修改时间、创建时间和最后访问时间。微软FAT协议不支持1980年以前的时间。
+>-   FATFS分区挂载与卸载：
+>    -   支持以只读属性挂载分区。当mount函数的入参为MS\_RDONLY时，所有的带有写入的接口，如write、mkdir、unlink，以及非O\_RDONLY属性的open，将均被拒绝。
+>    -   mount支持通过MS\_REMOUNT标记修改已挂载分区的权限。
+>    -   在umount操作前，需确保所有目录及文件全部关闭。

+    -   [Cow机制](#section172771130193610)
+    -   [LittleFS掉电保护](#section42941021173614)
+
+
+LittleFS主要用在微控制器和Flash上，是一种嵌入式文件系统，具有掉电恢复、擦写均衡、节省ROM/RAM空间等特点。
+
+## 运行机制<a name="section10284121317365"></a>
+
+最经典的掉电保护方法有两种，一种是使用日志，一种是通过COW方式。LittleFS结合了两种方法，并优化了两种方案的缺点，提供了一套掉电保护策略
+
+### 日志方式<a name="section13804114513361"></a>
+
+**图 1**  日志方式示意图<a name="fig8199182955716"></a>  
+![](figure/日志方式示意图.png "日志方式示意图")
+
+具体步骤为：
+
+1.  写入数据之前，先在日志区存储开始标志，记录要写入的数据位置和大小；
+2.  待写入的数据写入日志区；
+3.  待写入的数据写入数据区；
+4.  写入完成之后，在日志区记录结束标志。
+
+模拟掉电场景：
+
+1.  步骤1完成，步骤2没有完成；重启之后，保持原来的数据，日志无效；
+2.  步骤1，2完成了，步骤3没有完成，尝试把步骤2的数据写入到数据区；
+3.  步骤1，2，3完成了，步骤4没有完成，同样尝试把步骤2的数据写入到数据区；
+
+### Cow机制<a name="section172771130193610"></a>
+
+**图 2**  Cow机制示意图<a name="fig139293469719"></a>  
+![](figure/Cow机制示意图.png "Cow机制示意图")
+
+具体步骤为：
+
+1.  想更新节点F的数据，先申请一个新的节点，把F的旧数据拷贝过去，然后更新新的数据；
+2.  把父节点的指针指向新的节点，去掉旧节点的指针。
+
+模拟掉电场景：
+
+步骤1完成了，步骤2没有完成，则使用旧的数据，新的节点变成孤儿节点。
+
+### LittleFS掉电保护<a name="section42941021173614"></a>
+
+LittleFS结合了日志方式和COW机制两种方式进行掉电保护，并且优化了两种方案。
+
+文件系统有三要素，超级块，inode，以及数据，对应LittleFS来说，它把超级块以及inode通过日志的方式存储，两种采用统一的存储结构，后文称两者为元数据；普通数据则采用cow的方式存储，采用czt逆序链表的方式。
+
+![](figure/zh-cn_image_0000001124307264.png)
+
+**元数据的存储**
+
+元数据（对应root，dir）采用双block的方式存储，互为备份，每个block都有一个revision序号，值越大，表示block的数据越新，每个block默认可以存储最多0xff个文件的数据，如果超过这个值，则需要compact（压缩）。
+
+Compact是干什么呢？ 即当数据的大小大于某个值的时候，把数据整合，剔除同一个id的旧的数据，然后写入到备份block里面。如图所示：
+
+**图 3**  元数据存储示意图<a name="fig426811100598"></a>  
+![](figure/元数据存储示意图.png "元数据存储示意图")
+
+**普通数据的存储**
+
+LittleFS的数据采用链表的方式逆向管理。
+
+![](figure/zh-cn_image_0000001132085260.png)
+
+1.  采用逆向的指针，这样常规的追加数据，不需要额外的开销来重新建立所有的索引；
+2.  每个偶数block有多个指针，指向更远的数据，这样可以在检索的时候加快速度。

+## 基本概念<a name="section11374125415814"></a>
+
+C++作为目前使用最广泛的编程语言之一，支持类、封装、重载等特性，是在C语言基础上开发的一种面向对象的编程语言。
+
+### 运行机制<a name="section125251720195"></a>
+
+C++代码的识别主要由编译器支持，系统主要对全局对象进行构造函数调用，进行初始化操作。

+
+## 基础概念<a name="section17368154517335"></a>
+
+踩内存检测机制作为内核的可选功能，用于检测动态内存池的完整性。通过该机制，可以及时发现内存池是否发生了踩内存问题，并给出错误信息，便于及时发现系统问题，提高问题解决效率，降低问题定位成本。
+
+## 功能配置<a name="section4696190123420"></a>
+
+LOSCFG\_BASE\_MEM\_NODE\_INTEGRITY\_CHECK：开关宏，默认关闭；若打开这个功能，在target\_config.h中将这个宏定义为1。

+## 基础概念<a name="section1026719436293"></a>
+
+内存泄漏检测机制作为内核的可选功能，用于辅助定位动态内存泄漏问题。开启该功能，动态内存机制会自动记录申请内存时的函数调用关系（下文简称LR）。如果出现泄漏，就可以利用这些记录的信息，找到内存申请的地方，方便进一步确认。
+
+## 功能配置<a name="section13991354162914"></a>
+
+1.  LOSCFG\_MEM\_LEAKCHECK：开关宏，默认关闭；若打开这个功能，在target\_config.h中将这个宏定义为1。
+2.  LOSCFG\_MEM\_RECORD\_LR\_CNT：记录的LR层数，默认3层；每层LR消耗sizeof\(void \*\)字节数的内存。
+3.  LOSCFG\_MEM\_OMIT\_LR\_CNT：忽略的LR层数，默认4层，即从调用LOS\_MemAlloc的函数开始记录，可根据实际情况调整。为啥需要这个配置？有3点原因如下：
+    -   LOS\_MemAlloc接口内部也有函数调用；
+    -   外部可能对LOS\_MemAlloc接口有封装；
+    -   LOSCFG\_MEM\_RECORD\_LR\_CNT 配置的LR层数有限；
+
+
+正确配置这个宏，将无效的LR层数忽略，就可以记录有效的LR层数，节省内存消耗。
+
+## 开发指导<a name="section95828159308"></a>
+
+### 开发流程<a name="section369844416304"></a>
+
+该调测功能可以分析关键的代码逻辑中是否存在内存泄漏。开启这个功能，每次申请内存时，会记录LR信息。在需要检测的代码段前后，调用LOS\_MemUsedNodeShow接口，每次都会打印指定内存池已使用的全部节点信息，对比前后两次的节点信息，新增的节点信息就是疑似泄漏的内存节点。通过LR，可以找到具体申请的代码位置，进一步确认是否泄漏。
+
+调用LOS\_MemUsedNodeShow接口输出的节点信息格式如下：每1行为一个节点信息；第1列为节点地址，可以根据这个地址，使用GDB等手段查看节点完整信息；第2列为节点的大小，等于节点头大小+数据域大小；第3\~5列为函数调用关系LR地址，可以根据这个值，结合汇编文件，查看该节点具体申请的位置。
+
+```

+## 基础概念<a name="section52691565235"></a>
+
+内存信息包括内存池大小、内存使用量、剩余内存大小、最大空闲内存、内存水线、内存节点数统计、碎片率等。
+
+-   内存水线：即内存池的最大使用量，每次申请和释放时，都会更新水线值，实际业务可根据该值，优化内存池大小；
+
+-   碎片率：衡量内存池的碎片化程度，碎片率高表现为内存池剩余内存很多，但是最大空闲内存块很小，可以用公式（fragment=100-最大空闲内存块大小/剩余内存大小）来度量；
+
+-   其他参数：通过调用接口（详见[内存管理](kernel-lite-mini-basic-memory.md)章节接口说明），扫描内存池的节点信息，统计出相关信息。
+
+## 功能配置<a name="section470611682411"></a>
+
+LOSCFG\_MEM\_WATERLINE：开关宏，默认打开；若关闭这个功能，在target\_config.h中将这个宏定义为0。如需获取内存水线，需要打开该配置。
+
+## 开发指导<a name="section9368374243"></a>
+
+### 开发流程<a name="section679912407257"></a>
+
+关键结构体介绍：
+
+```
+typedef struct {
+    UINT32 totalUsedSize;       // 内存池的内存使用量
+    UINT32 totalFreeSize;       // 内存池的剩余内存大小
+    UINT32 maxFreeNodeSize;     // 内存池的最大空闲内存块大小
+    UINT32 usedNodeNum;         // 内存池的非空闲内存块个数
+    UINT32 freeNodeNum;         // 内存池的空闲内存块个数
+#if (LOSCFG_MEM_WATERLINE == 1) // 默认打开，如需关闭，在target_config.h中将该宏设置为0
+    UINT32 usageWaterLine;      // 内存池的水线值
+#endif
+} LOS_MEM_POOL_STATUS;
+```
+
+-   内存水线获取：调用LOS\_MemInfoGet接口，第1个参数是内存池首地址，第2个参数是LOS\_MEM\_POOL\_STATUS类型的句柄，其中字段usageWaterLine即水线值。
+
+-   内存碎片率计算：同样调用LOS\_MemInfoGet接口，可以获取内存池的剩余内存大小和最大空闲内存块大小，然后根据公式（fragment=100-最大空闲内存块大小/剩余内存大小）得出此时的动态内存池碎片率。
+

+## 基本概念<a name="section2741911123412"></a>
+
+OpenHarmony LiteOS-M提供异常接管调测手段，帮助开发者定位分析问题。异常接管是操作系统对运行期间发生的异常情况进行处理的一系列动作，例如打印异常发生时异常类型、发生异常时的系统状态、当前函数的调用栈信息、CPU现场信息、任务调用堆栈等信息。
+
+## 运行机制<a name="section16618124317346"></a>
+
+栈帧用于保存函数调用过程中的函数参数、变量、返回值等信息。调用函数时，会创建子函数的栈帧，同时将函数入参、局部变量、寄存器入栈。栈帧从高地址向低地址生长。以ARM32 CPU架构为例，每个栈帧中都会保存PC、LR、SP和FP寄存器的历史值。LR链接寄存器（Link Register）指向函数的返回地址，FP帧指针寄存器（Frame Point）指向当前函数的父函数的栈帧起始地址。利用FP寄存器可以得到父函数的栈帧，从栈帧中获取父函数的FP，就可以得到祖父函数的栈帧，以此类推，可以追溯程序调用栈，得到函数间的调用关系。
+
+当系统发生异常时，系统打印异常函数的栈帧中保存的寄存器内容，以及父函数、祖父函数的栈帧中的LR链接寄存器、FP帧指针寄存器内容，用户就可以据此追溯函数间的调用关系，定位异常原因。
+
+堆栈分析原理如下图所示，实际堆栈信息根据不同CPU架构有所差异，此处仅做示意。
+
+**图 1**  堆栈分析原理示意图<a name="fig5280123462820"></a>  
+![](figure/堆栈分析原理示意图.png "堆栈分析原理示意图")
+
+图中不同颜色的寄存器表示不同的函数。可以看到函数调用过程中，寄存器的保存。通过FP寄存器，栈回溯到异常函数的父函数，继续按照规律对栈进行解析，推出函数调用关系，方便用户定位问题。
+
+## 接口说明<a name="section16111931351"></a>

+1.  使用示例中有问题的代码，编译、运行工程，在串口终端中查看异常信息输出。示例代码模拟异常代码，实际产品开发时使用异常调测机制定位异常问题。
+
+    本示例演示异常输出，包含1个任务，该任务入口函数模拟若干函数调用，最终调用一个模拟异常的函数。代码实现如下：
+
+    ```
+    #include <stdio.h>
+    #include "los_config.h"
+    #include "los_interrupt.h"
+    #include "los_task.h"
+    
+    UINT32 g_taskExcId;
+    #define TSK_PRIOR 4
+    
+    /* 模拟异常函数 */
+    	
+    UINT32 Get_Result_Exception_0(UINT16 dividend){
+        UINT32 divisor = 0;
+        UINT32 result = dividend / divisor;
+        return result;
+    }
+    
+    UINT32 Get_Result_Exception_1(UINT16 dividend){
+        return Get_Result_Exception_0(dividend);
+    }
+    
+    UINT32 Get_Result_Exception_2(UINT16 dividend){
+        return Get_Result_Exception_1(dividend);
+    }
+    
+    UINT32 Example_Exc(VOID)
+    {
+        UINT32 ret;
+    
+        printf("Enter Example_Exc Handler.\r\n");
+    
+        /* 模拟函数调用 */
+        ret = Get_Result_Exception_2(TSK_PRIOR);
+        printf("Divided result =%u.\r\n", ret);
+    
+        printf("Exit Example_Exc Handler.\r\n");
+        return ret;
+    }
+    
+    
+    /* 任务测试入口函数，创建一个会发生异常的任务 */
+    UINT32 Example_Exc_Entry(VOID)
+    {
+        UINT32 ret;
+        TSK_INIT_PARAM_S initParam;
+    
+        /* 锁任务调度，防止新创建的任务比本任务高而发生调度 */
+        LOS_TaskLock();
+    
+        printf("LOS_TaskLock() Success!\r\n");
+    
+        initParam.pfnTaskEntry = (TSK_ENTRY_FUNC)Example_Exc;
+        initParam.usTaskPrio = TSK_PRIOR;
+        initParam.pcName = "Example_Exc";
+        initParam.uwStackSize = LOSCFG_SECURE_STACK_DEFAULT_SIZE;
+        /* 创建高优先级任务，由于锁任务调度，任务创建成功后不会马上执行 */
+        ret = LOS_TaskCreate(&g_taskExcId, &initParam);
+        if (ret != LOS_OK) {
+            LOS_TaskUnlock();
+    
+            printf("Example_Exc create Failed!\r\n");
+            return LOS_NOK;
+        }
+    
+        printf("Example_Exc create Success!\r\n");
+    
+        /* 解锁任务调度，此时会发生任务调度，执行就绪队列中最高优先级任务 */
+        LOS_TaskUnlock();
+    
+        return LOS_OK;
+    }
+    ```
+
+
+1.  上述代码串口终端输出异常信息如下：
+
+    ```
+    entering kernel init...
+    LOS_TaskLock() Success!
+    Example_Exc create Success!
+    Entering scheduler

+
+### 定位流程<a name="section197332323815"></a>
+
+异常接管一般的定位步骤如下：
+
+1.  打开编译后生成的镜像反汇编（asm）文件。如果默认没有生成，可以使用<u>objdump</u>工具生成，命令为：
+
+    ```
+     arm-none-eabi-objdump -S -l XXX.elf
+    ```
+
+
+1.  搜索PC指针（指向当前正在执行的指令）在asm中的位置，找到发生异常的函数。
+
+    PC地址指向发生异常时程序正在执行的指令。在当前执行的二进制文件对应的asm文件中，查找PC值0x80037da，找到当前CPU正在执行的指令行，反汇编如下所示：
+
+    ```
+    UINT32 Get_Result_Exception_0(UINT16 dividend){
+     80037c8:	b480      	push	{r7}
+     80037ca:	b085      	sub	sp, #20
+     80037cc:	af00      	add	r7, sp, #0
+     80037ce:	4603      	mov	r3, r0
+     80037d0:	80fb      	strh	r3, [r7, #6]
+    kernel_liteos_m\targets\cortex-m7_nucleo_f767zi_gcc/Core/Src/exc_example.c:10
+        UINT32 divisor = 0;
+     80037d2:	2300      	movs	r3, #0
+     80037d4:	60fb      	str	r3, [r7, #12]
+    kernel_liteos_m\targets\cortex-m7_nucleo_f767zi_gcc/Core/Src/exc_example.c:11
+        UINT32 result = dividend / divisor;
+     80037d6:	88fa      	ldrh	r2, [r7, #6]
+     80037d8:	68fb      	ldr	r3, [r7, #12]
+     80037da:	fbb2 f3f3 	udiv	r3, r2, r3
+     80037de:	60bb      	str	r3, [r7, #8]
+    ```
+
+
+1.  可以看到:
+    1.  异常时CPU正在执行的指令是udiv	r3, r2, r3，其中r3取值为0，导致发生除零异常。
+    2.  异常发生在函数Get\_Result\_Exception\_0中。
+
+2.  根据LR值查找异常函数的父函数。
+
+    包含LR值0x80037fe的反汇编如下所示：
+
+    ```
+    080037ec <Get_Result_Exception_1>:
+    Get_Result_Exception_1():
+    kernel_liteos_m\targets\cortex-m7_nucleo_f767zi_gcc/Core/Src/exc_example.c:15
+    UINT32 Get_Result_Exception_1(UINT16 dividend){
+     80037ec:	b580      	push	{r7, lr}
+     80037ee:	b082      	sub	sp, #8
+     80037f0:	af00      	add	r7, sp, #0
+     80037f2:	4603      	mov	r3, r0
+     80037f4:	80fb      	strh	r3, [r7, #6]
+    kernel_liteos_m\targets\cortex-m7_nucleo_f767zi_gcc/Core/Src/exc_example.c:16
+        return Get_Result_Exception_0(dividend);
+     80037f6:	88fb      	ldrh	r3, [r7, #6]
+     80037f8:	4618      	mov	r0, r3
+     80037fa:	f7ff ffe5 	bl	80037c8 <Get_Result_Exception_0>
+     80037fe:	4603      	mov	r3, r0
+    ```
+
+
+1.  LR值80037fe上一行是bl	80037c8 <Get\_Result\_Exception\_0\>，此处调用了异常函数，调用异常函数的父函数为Get\_Result\_Exception\_1\(\)。
+2.  重复步骤3，解析异常信息中backtrace start至backtrace end之间的LR值，得到调用产生异常的函数调用栈关系，找到异常原因。

+## 内核简介<a name="section1429342661510"></a>
+
+OpenHarmony LiteOS-M内核是面向IoT领域构建的轻量级物联网操作系统内核，具有小体积、低功耗、高性能的特点。其代码结构简单，主要包括内核最小功能集、内核抽象层、可选组件以及工程目录等。OpenHarmony LiteOS-M内核架构包含硬件相关层以及硬件无关层，如下图所示，其中Kernel Arch模块属于硬件相关层，该模块按不同编译工具链、芯片架构分类，提供统一的HAL（Hardware Abstraction Layer）接口，提升了硬件易适配性，满足AIoT类型丰富的硬件和编译工具链的拓展；Components等其他模块属于硬件无关层，其中Kernel Task等内核模块提供基础能力，Components模块提供网络、文件系统等组件能力，Utils模块提供错误处理、调测等能力，KAL（Kernel Abstraction Layer）模块提供统一的标准接口。

+
+CPU体系架构分为通用架构定义和特定架构定义两层，通用架构定义层为所有体系架构都需要支持和实现的接口，特定架构定义层为特定体系架构所特有的部分。在新增一个体系架构的时候，必须需要实现通用架构定义层，如果该体系架构还有特有的功能，可以在特定架构定义层来实现。

+OpenHarmony LiteOS-M内核的编译构建系统是一个基于gn和ninja的组件化构建系统，支持按组件配置、裁剪和拼装，按需构建出定制化的产品。编译构建系统的详细信息可以参考[考编译构建概](../subsystems/subsys-build-mini-lite.md#section10958256161119)。本文主要介绍如何基于gn和ninja编译LiteOS-M工程。
+
+## 搭建开发环境<a name="section157851447151716"></a>
+
+在搭建各个开发板环境前，需要完成OpenHarmony系统基础环境搭建。系统基础环境主要是指OpenHarmony的编译环境和开发环境，详细介绍请参考官方站点[搭建系统基础环境](../quick-start/quickstart-lite-env-setup-des.md)。开发者需要根据环境搭建文档，完成下述软件的安装：Python3.7+、gn、ninja、hb。对于LiteOS-M内核，还需要安装ARM GCC编译工具链。
+
+## 获取OpenHarmony源码<a name="section381985201816"></a>
+
+开发者需要在Linux服务器上通过Git克隆获取OpenHarmony最新源码，详细的源码获取方式，请见[源码获取](../get-code/sourcecode-acquire.md)。获取OpenHarmony完整仓代码后，假设克隆目录为\~/openHarmony。
+
+## 获取示例工程源码<a name="section204717216181"></a>
+
+以开发板Nucleo-F767Zi为例，演示如何编译运行OpenHarmony LiteOS-M内核工程。在本地目录，执行下述命令克隆示例代码。
+
+```
+git clone https://gitee.com/harylee/nucleo_f767zi.git
+```
+
+假设克隆到的代码目录为\~/nucleo\_f767zi。 执行如下命令把代码目录的device、vendor目录复制到openHarmony工程的相应目录。
+
+```
+cp -r ~/nucleo_f767zi/device/st  ~/openHarmony/device/st
+cp -r ~/nucleo_f767zi/vendor/st  ~/openHarmony/vendor/st
+```
+
+关于示例代码目录的说明，可以参考资料站点[板级目录规范](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/porting/%E7%A7%BB%E6%A4%8D%E6%A6%82%E8%BF%B0-0.md#section6204129143013)。如果需要自行移植开发板，请参考[板级系统移植](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/porting/%E6%9D%BF%E7%BA%A7%E7%B3%BB%E7%BB%9F%E7%A7%BB%E6%A4%8D.md)。
+
+## 编译运行<a name="section9772514181917"></a>
+
+编译运行前，把交叉编译工具链bin目录配置到PATH环境变量中或者在device/st/nucleo\_f767zi/liteos\_m/config.gni文件中把board\_toolchain\_path配置项设置为交叉编译工具链bin目录。 在OpenHarmony根目录，执行hb set设置产品路径，选择nucleo\_f767zi产品，然后执行hb build开启编译。如下：
+
+```
+user@dev:~/OpenHarmony$ hb set
+[OHOS INFO] Input code path:          # 直接按回车，然后选择nucleo_f767zi产品即可
+OHOS Which product do you need?  nucleo_f767zi@st
+user@dev:~/OpenHarmony$ hb build
+```
+
+最终的镜像生成在\~/openHarmony/out/nucleo\_f767zi/目录中，通过STM32 ST-LINK Utility软件将镜像文件下载至单板查看运行效果。

+## 概述<a name="section18322139164413"></a>
+
+NFS是Network File System（网络文件系统）的缩写。它最大的功能是可以通过网络，让不同的机器、不同的操作系统彼此分享其他用户的文件。因此，用户可以简单地将它看做是一个文件系统服务，在一定程度上相当于Windows环境下的共享文件夹。
+
+NFS客户端用户，能够将网络远程的NFS服务端分享的目录挂载到本地端的机器中，运行程序和共享文件，但不占用当前的系统资源，所以，在本地端的机器看起来，远程服务端的目录就好像是自己的一个磁盘一样。
+
+## 注意事项<a name="section532912331467"></a>
+
+-   当前NFS文件不支持权限控制，请在创建NFS目录和文件时使用777权限。
+
+-   当前NFS文件不支读阻塞和写阻塞。
+
+-   当前NFS文件不支持信号功能。
+
+-   当前NFS文件系统mount路径长度（不包含IP的长度）不超过255个字符，超过时返回ENAMETOOLONG错误。
+
+-   当前NFS文件支持的操作有：open, close, read, write, seek, dup, dup2, sync, opendir, closedir, readdir, readdir\_r, rewinddir,  scandir, statfs, remove, unlink, mkdir, rmdir, rename, stat, stat64, seek64, mmap, mount, umount。
+
+-   当前NFS支持TCP和UDP两种传输层协议，默认使用TCP。
+
+-   open打开一个文件，参数有O\_TRUNC时，必须同时拥有写的权限，才会将文件中的内容清空。
+
+-   在文件未关闭的情况下，rename\(\)函数重命名A为B之后，不会改变文件fd。
+
+-   NFS功能目前处于beta测试阶段，可能存在功能不稳定的情况，建议您不要用于正式商用产品当中。
+
+
+## 开发指导<a name="section166873374711"></a>
+
+1.  **搭建NFS服务器**。
+
+    这里以Ubuntu操作系统为例，说明服务器端设置步骤。
+
+    1.  安装NFS服务器软件。
+
+        设置好Ubuntu系统的下载源，保证网络连接好的情况下执行：
+
+        ```
+        sudo apt-get install nfs-kernel-server
+        ```
+
+    2.  创建用于挂载的目录并设置完全权限
+
+        ```
+        mkdir /home/sqbin/nfs
+        sudo chmod 777 /home/sqbin/nfs
+        ```
+
+    3.  设置和启动NFS server。
+
+        修改NFS配置文件/etc/exports，添加如下一行：
+
+        ```
+        /home/sqbin/nfs *(rw,no_root_squash,async)
+        ```
+
+        其中/home/sqbin/nfs是NFS共享的根目录。
+
+        执行以下命令启动NFS server：
+
+        ```
+        sudo /etc/init.d/nfs-kernel-server start
+        ```
+
+        执行以下命令重启NFS server：
+
+        ```
+        sudo /etc/init.d/nfs-kernel-server restart
+        ```
+
+
+2.  **设置单板为NFS客户端**。
+
+    本指导中的NFS客户端指运行OpenHarmony内核的设备。
+
+    1.  硬件连接设置。
+
+        OpenHarmony内核设备连接到NFS服务器的网络。设置两者IP，使其处于同一网段。比如，设置NFS服务器的IP为10.67.212.178/24，设置OpenHarmony内核设备IP为10.67.212.3/24，注意：此IP为内网私有IP地址，用户使用时有差异，以用户实际IP为准。
+
+        OpenHarmony内核设备上的IP信息可通过ifconfig命令查看。
+
+    2.  启动网络，确保单板到NFS服务器之间的网络通畅。
+
+        启动以太网或者其他类型网络，使用ping命令检查到服务器的网络是否通畅。
+
+        ```
+        OHOS # ping 10.67.212.178
+        [0]Reply from 10.67.212.178: time=1ms TTL=63
+        [1]Reply from 10.67.212.178: time=0ms TTL=63
+        [2]Reply from 10.67.212.178: time=1ms TTL=63
+        [3]Reply from 10.67.212.178: time=1ms TTL=63
+        --- 10.67.212.178 ping statistics ---
+        4 packets transmitted, 4 received, 0 loss
+        ```
+
+        客户端NFS初始化，运行命令：
+
+        ```
+        OHOS # mkdir /nfs
+        OHOS # mount 10.67.212.178:/home/sqbin/nfs /nfs nfs 1011 1000
+        ```
+
+        将从串口得到如下回应信息，表明初始化NFS客户端成功。
+
+        ```
+        OHOS # mount 10.67.212.178:/home/sqbin/nfs /nfs nfs 1011 1000
+        Mount nfs on 10.67.212.178:/home/sqbin/nfs, uid:1011, gid:1000
+        Mount nfs finished.
+        ```
+
+        该命令将服务器10.67.212.178上的/home/sqbin/nfs目录mount在OpenHarmony内核设备上的/nfs上。
+
+        >![](../public_sys-resources/icon-note.gif) **说明：** 
+        >本例默认nfs server已经配置可用，即示例中服务器10.67.212.178上的/home/sqbin/nfs已配置可访问。
+
+        mount命令的格式为：
+
+        ```
+        mount <SERVER_IP:SERVER_PATH> <CLIENT_PATH> nfs
+        ```
+
+        其中“SERVER\_IP“表示服务器的IP地址；“SERVER\_PATH“表示服务器端NFS共享目录路径；“CLIENT\_PATH“表示设备上的NFS路径。
+
+        如果不想有NFS访问权限限制，请在Linux命令行将NFS根目录权限设置成777：
+
+        ```
+        chmod -R 777 /home/sqbin/nfs
+        ```
+
+        至此，NFS客户端设置完毕。NFS文件系统已成功挂载。
+
+
+3.  **利用NFS共享文件**。
+
+    在NFS服务器下新建目录dir，并保存。在OpenHarmony内核下运行ls命令：
+
+    ```
+    OHOS # ls /nfs
+    ```
+
+    则可从串口得到如下回应：
+
+    ```
+    OHOS # ls /nfs 
+    Directory /nfs:                 
+    drwxr-xr-x 0        u:0     g:0     dir
+    ```
+
+    可见，刚刚在NFS服务器上新建的dir目录已同步到客户端\(OpenHarmony内核系统\)的/nfs目录，两者保持同步。
+
+    同样地，在客户端\(OpenHarmony内核系统\)上创建文件和目录，在NFS服务器上也可以访问，读者可自行体验。
+
+    **平台差异性：**
+
+    目前，NFS客户端仅支持NFS v3部分规范要求，因此对于规范支持不全的服务器，无法完全兼容。在开发测试过程中，建议使用Linux的NFS server，因为其对NFS支持很完善。

+由于不同类型的文件系统接口不统一，若系统中有多个文件系统类型，访问不同的文件系统就需要使用不同的非标准接口。而通过在系统中添加VFS层，提供统一的抽象接口，屏蔽了底层异构类型的文件系统的差异，使得访问文件系统的系统调用不用关心底层的存储介质和文件系统类型，提高开发效率。VFS和各个具体文件系统的关系如下：
+
+**图 1**  VFS和各个文件系统的关系<a name="fig633144419295"></a>  
+![](figure/VFS和各个文件系统的关系.png "VFS和各个文件系统的关系")
+
+OpenHarmony内核中，VFS框架是通过在内存中的树结构来实现的，树的每个结点都是一个inode结构体。设备注册和文件系统挂载后会根据路径在树中生成相应的结点。VFS最主要是两个功能：
+
+-   查找节点。
+-   统一调用（标准）。
+
+## 运作机制<a name="section18114182834215"></a>
+
+通过VFS层，可以使用标准的Unix文件操作函数（如open、read、write等）来实现对不同介质上不同文件系统的访问。
+
+VFS框架内存中的inode树结点有三种类型：
+
+-   虚拟结点：作为VFS框架的虚拟文件，保持树的连续性，如/usr、/usr/bin。
+-   设备结点：/dev目录下，对应一个设备，如/dev/mmcblk0。
+-   挂载点：挂载具体文件系统，如/vs/sd、/mnt。
+
+**图 2**  文件系统树形结构<a name="fig1648112392612"></a>  
+![](figure/文件系统树形结构.png "文件系统树形结构")
+
+## 注意事项<a name="section18311145173712"></a>
+
+-   VFS下的所有文件系统，创建的目录名和文件名最多只可以有255个字节，能支持的全路径长度最长为259字节，超过这个路径长度的文件和目录无法创建。
+
+-   目前仅有jffs2文件系统支持完整的权限控制。
+
+-   inode\_find\(\)函数调用后会使查找到的inode节点连接数+1，调用完成后需要调用inode\_release\(\)使连接数-1，所以一般inode\_find\(\)要和inode\_release\(\)配套使用。
+
+-   设备分为字符设备和块设备，为了块设备上的文件系统系统数据安全，需挂载相应文件系统后通过文件系统接口操作数据。
+
+-   los\_vfs\_init\(\)只能调用一次，多次调用将会造成文件系统异常。
+
+-   目前OpenHarmony内核所有的文件系统中的文件名和目录名中只可以出现“-” 与“\_”两种特殊字符，使用其他特殊字符可能造成的后果不可预知，请谨慎为之。
+
+-   OpenHarmony内核支持open\(\)+O\_DIRECTORY的方法获取目录数据信息。
+
+-   挂载点必须为空目录，不能重复挂载至同一挂载点或挂载至其他挂载点下的目录或文件，错误挂载可能损坏设备及系统。
+
+-   open打开一个文件时，参数O\_RDWR、O\_WRONLY、O\_RDONLY互斥，只能出现一个，若出现2个或以上作为open的参数，文件读写操作会被拒绝，并返回EACCESS错误码，禁止使用。
+
+-   OpenHarmony内核文件系统在umount操作之前，需确保所有目录及文件全部关闭，否则umount会失败。如果强制umount，可能导致包括但不限于文件系统损坏、设备损坏等问题。
+
+-   SD卡移除前，需确保所有目录及文件全部关闭，并进行umount操作。如果强制拔卡，可能导致包括但不限于SD数据丢失、SD卡损坏等问题。
+
+
+## 开发指导<a name="section422619258380"></a>
+
+**开发流程**
+
+推荐驱动开发人员使用VFS框架来注册/卸载设备，即调用register\_driver\(\)、register\_blockdriver\(\)接口生成设备结点，应用层使用open\(\)、read\(\)操作设备（字符设备）文件来调用驱动。
+
+**文件描述符**
+
+本系统中，进程的文件描述符最多有256个（File和Socket描述符合并统计），系统文件描述符共640个，系统文件描述符规格：
+
+-   File描述符，普通文件描述符，系统总规格为512。
+
+-   Socket描述符，系统总规格为128。
+
+
+**VFS支持的操作**
+
+open, close, read, write, seek, ioctl, fcntl, mmap, sync, dup, dup2, truncate, opendir, closedir, readdir,  rewinddir, mount, umount, statfs, unlink, remove, mkdir, rmdir, rename, stat, utime, seek64, fallocate, fallocate64, truncate64, chmod, chown。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   当前只提供修改jffs2文件以及vfs设备节点属性的接口，各个系统对只读等属性有各自的处理方式。
+>-   在OpenHarmony内核中属性并不冲突（可以任意修改）。
+>-   在OpenHarmony内核中只读属性文件/目录不允许被删除。
+>-   在OpenHarmony内核中只读属性文件/目录允许rename。
+>-   只读文件不允许以O\_CREAT、O\_TRUNC，以及有含有写的权限的方式打开。
+>-   在OpenHarmony内核中设置的系统文件加上隐藏属性，在Windows中只能通过命令行找到（在显示，不显示隐藏文件的属性情况下都不能看到）。

+## 基本概念<a name="section1392116583424"></a>
+
+内存管理是开发过程中必须要关注的重要过程，它包括内存的分配、使用和回收。
+
+良好的内存管理对于提高软件性能和可靠性有着十分重要的意义。
+
+## 使用场景<a name="section159581619194319"></a>
+
+针对用户态开发，OpenHarmony内核提供了一套内存系统调用接口，支持内存的申请释放、重映射、内存属性的设置等，还有C库的标准内存操作函数。

+## 基本概念<a name="section29197338383"></a>
+
+从系统的角度看，进程是资源管理单元。进程可以使用或等待CPU、使用内存空间等系统资源，并独立于其它进程运行。
+
+OpenHarmony内核的进程模块可以给用户提供多个进程，实现了进程之间的切换和通信，帮助用户管理业务程序流程。这样用户可以将更多的精力投入到业务功能的实现中。
+
+OpenHarmony内核中的进程采用抢占式调度机制，支持时间片轮转调度方式。
+
+OpenHarmony内核的进程一共有32个优先级\(0-31\)，用户进程可配置的优先级有22个\(10-31\)，最高优先级为10，最低优先级为31。
+
+高优先级的进程可抢占低优先级进程，低优先级进程必须在高优先级进程阻塞或结束后才能得到调度。
+
+每一个用户态进程均拥有自己独立的进程空间，相互之间不可见，实现进程间隔离。
+
+用户态根进程init由内核态创建，其它用户态进程均由init进程fork而来。
+
+**进程状态说明：**
+
+-   初始化（Init）：该进程正在被创建。
+
+-   就绪（Ready）：该进程在就绪列表中，等待CPU调度。
+
+-   运行（Running）：该进程正在运行。
+
+-   阻塞（Pending）：该进程被阻塞挂起。本进程内所有的线程均被阻塞时，进程被阻塞挂起。
+
+-   僵尸态（Zombies）：该进程运行结束，等待父进程回收其控制块资源。
+
+
+**图 1**  进程状态迁移示意图<a name="fig1877059202911"></a>  
+![](figure/进程状态迁移示意图.png "进程状态迁移示意图")
+
+**进程状态迁移说明：**
+
+-   Init→Ready：
+
+    进程创建或fork时，拿到该进程控制块后进入Init状态，处于进程初始化阶段，当进程初始化完成将进程插入调度队列，此时进程进入就绪状态。
+
+-   Ready→Running：
+
+    进程创建后进入就绪态，发生进程切换时，就绪列表中最高优先级的进程被执行，从而进入运行态。若此时该进程中已无其它线程处于就绪态，则该进程从就绪列表删除，只处于运行态；若此时该进程中还有其它线程处于就绪态，则该进程依旧在就绪队列，此时进程的就绪态和运行态共存。
+
+-   Running→Pending：
+
+    进程内所有的线程均处于阻塞态时，进程在最后一个线程转为阻塞态时，同步进入阻塞态，然后发生进程切换。
+
+-   Pending→Ready：
+
+    阻塞进程内的任意线程恢复就绪态时，进程被加入到就绪队列，同步转为就绪态。
+
+-   Ready→Pending：
+
+    进程内的最后一个就绪态线程处于阻塞态时，进程从就绪列表中删除，进程由就绪态转为阻塞态。
+
+-   Running→Ready：
+
+    进程由运行态转为就绪态的情况有以下两种：
+
+    1.  有更高优先级的进程创建或者恢复后，会发生进程调度，此刻就绪列表中最高优先级进程变为运行态，那么原先运行的进程由运行态变为就绪态。
+    2.  若进程的调度策略为SCHED\_RR，且存在同一优先级的另一个进程处于就绪态，则该进程的时间片消耗光之后，该进程由运行态转为就绪态，另一个同优先级的进程由就绪态转为运行态。
+
+-   Running→Zombies：
+
+    当进程的主线程或所有线程运行结束后，进程由运行态转为僵尸态，等待父进程回收资源。
+
+
+## 使用场景<a name="section85513272398"></a>
+
+进程创建后，用户只能操作自己进程空间的资源，无法操作其它进程的资源（共享资源除外）。 用户态允许进程挂起，恢复，延时等操作，同时也可以设置用户态进程调度优先级和调度策略，获取进程调度优先级和调度策略。进程结束的时候，进程会主动释放持有的进程资源，但持有的进程pid资源需要父进程通过wait/waitpid或父进程退出时回收。

+-   同一路径下，源文件与目的文件不能重名。
+-   源文件必须存在，且不为目录。
+-   源文件路径支持“\*”和“？”通配符，“\*”代表任意多个字符，“？”代表任意单个字符。目的路径不支持通配符。当源路径可匹配多个文件时，目的路径必须为目录。
+-   目的路径为目录时，该目录必须存在。此时目的文件以源文件命名。
+-   目的路径为文件时，所在目录必须存在。此时拷贝文件的同时为副本重命名。
+-   目前不支持多文件拷贝。参数大于2个时，只对前2个参数进行操作。
+-   目的文件不存在时创建新文件，已存在则覆盖。
+
+拷贝系统重要资源时，会对系统造成死机等重大未知影响，如用于拷贝/dev/uartdev-0 文件时，会产生系统卡死现象。

+-   [使用场景](#section2350114718546)
+-   [使用方法](#section3305151511559)
+
+## 使用场景<a name="section2350114718546"></a>
+
+在系统运行出现无响应等情况时，可以通过魔法键功能确定系统是否被锁中断（魔法键也无响应）或者查看系统任务运行状态等信息。
+
+在中断有响应的情况下，可以通过魔法键查看task信息中  cpup（CPU占用率）看是哪个任务长时间占用CPU导致系统其他任务无响应（一般为比较高优先级任务一直抢占CPU，导致低优先级任务无响应）。
+
+## 使用方法<a name="section3305151511559"></a>
+
+1.  配置宏LOSCFG\_ENABLE\_MAGICKEY。
+
+魔法键依赖于宏LOSCFG\_ENABLE\_MAGICKEY，使用时通过menuconfig在配置项中开启“Enable  MAGIC KEY”：
+
+Debug ---\> Enable MAGIC KEY；若关闭该选项，则魔法键失效。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>1.  可以在menuconfig中，将光标移动到LOSCFG\_ENABLE\_MAGICKEY上，输入“？”，查看帮助信息。
+
+2. 输入“ctrl + r”键，打开魔法键检测功能。
+
+在连接UART或者USB转虚拟串口的情况下，输入“ctrl + r” 键，打开魔法键检测功能，输出 “Magic key on”；再输入一次后，则关闭魔法键检测功能，输出“Magic key off”。魔法键功能如下：
+
+-   ctrl + z：帮助键，输出相关魔法键简单介绍；
+
+-   ctrl + t：输出任务相关信息；
+
+-   ctrl + p：系统主动进入panic，输出panic相关信息后，系统会挂住；
+
+-   ctrl + e：系统进行简单完整性内存池检查，检查出错会输出相关错误信息，检查正常会输出“system memcheck  over, all passed!”。
+
+
+>![](../public_sys-resources/icon-notice.gif) **须知：** 
+>魔法键检测功能打开情况下，如果需要通过UART或者USB转虚拟串口输入特殊字符需避免与魔法键值重复，否则魔法键会被误触发，而原有设计功能可能出现错误。

+## 命令功能<a name="section201149459368"></a>
+
+在以太网中，主机之间的通信是直接使用MAC地址（非IP地址）来通信的，所以，对于使用IP通信的协议，必须能够将IP地址转换成MAC地址，才能在局域网（以太网）内通信。解决这个问题的方法就是主机存储一张IP和MAC地址对应的表，即ARP缓存，主机要往一个局域网内的目的IP地址发送IP包时，就可以从ARP缓存表中查询到目的MAC地址。ARP缓存是由TCP/IP协议栈维护的，用户可通过ARP命令查看和修改ARP表。

+该命令当前仅支持执行有效的二进制程序，程序成功执行，默认后台运行，但与Shell共用终端，可能会导致程序打印输出与Shell输出交错显示。
+
+## 使用实例<a name="section13736564418"></a>
+
+举例：
+
+输入exec helloworld。
+
+## 输出说明<a name="section194005101413"></a>
+
+```
+OHOS # exec helloworld
+OHOS # hello world!
+```
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>可执行文件执行后，先打印“OHOS \#”提示符原因：目前Shell “exec”命令执行均为后台执行，结果可能导致提示符提前打印。

+# Shell介绍<a name="ZH-CN_TOPIC_0000001053967735"></a>
+
+-   [注意事项](#section12298165312328)
+
+OpenHarmony内核提供的Shell支持调试常用的基本功能，包含系统、文件、网络和动态加载相关命令。同时OpenHarmony内核的Shell支持添加新的命令，可以根据需求来进行定制。
+
+-   系统相关命令：提供查询系统任务、内核信号量、系统软件定时器、CPU占用率、当前中断等相关信息的能力。
+
+-   文件相关命令：支持基本的ls、cd等功能。
+
+-   网络相关命令：支持查询接到开发板的其他设备的IP、查询本机IP、测试网络连接、设置开发板的AP和station模式等相关功能。
+
+    新增命令的详细流程可参见[开发指导](kernel-lite-small-shell-guide.md)和[编程实例](kernel-lite-small-shell-sample.md)。
+
+
+## 注意事项<a name="section12298165312328"></a>
+
+在使用Shell功能的过程中，需要注意以下几点：
+
+-   Shell功能支持使用exec命令来运行可执行文件。
+-   Shell功能支持默认模式下英文输入。如果出现用户在UTF-8格式下输入了中文字符的情况，只能通过回退三次来删除。
+
+-   Shell功能支持shell命令、文件名及目录名的Tab键联想补全。若有多个匹配项，则根据共同字符， 打印多个匹配项。对于过多的匹配项（打印多于24行），将会进行打印询问（Display  all num  possibilities?（y/n）），用户可输入y选择全部打印，或输入n退出打印，选择全部打印并打印超过24行后，会进行--More--提示，此时按回车键继续打印，按q键退出（支持Ctrl+c退出\)。
+
+-   Shell端工作目录与系统工作目录是分开的，即通过Shell端cd  pwd等命令是对Shell端工作目录进行操作，通过chdir getcwd等命令是对系统工作目录进行操作，两个工作目录相互之间没有联系。当文件系统操作命令入参是相对路径时要格外注意。
+
+-   在使用网络Shell指令前，需要先调用tcpip\_init函数完成网络初始化并完成telnet连接后才能起作用，内核默认不初始化tcpip\_init。
+
+-   不建议使用Shell命令对/dev目录下的设备文件进行操作，这可能会引起不可预知的结果。
+
+-   Shell功能不符合POSIX标准，仅供调试使用。
+
+    >![](../public_sys-resources/icon-notice.gif) **须知：** 
+    >Shell功能仅供调试使用，在Debug版本中开启（使用时通过menuconfig在配置项中开启"LOSCFG\_DEBUG\_VERSION"编译开关进行相关控制），商用产品中禁止包含该功能。

+## 开发指导<a name="section22071515161018"></a>
+
+新增Shell命令的典型开发流程如下：
+
+1.  包含如下头文件：
+
+    ```
+    #include "shell.h"
+    #include "shcmd.h"
+    ```
+
+2.  注册命令。用户可以选择静态注册命令方式和系统运行时动态注册命令方式，静态注册命令方式一般用在系统常用命令注册，动态注册命令方式一般用在用户命令注册。
+
+    1.  静态注册命令方式：
+
+        1.  通过宏的方式注册。
+
+            这个宏的原型为：
+
+            ```
+            SHELLCMD_ENTRY(l, cmdType, cmdKey, paraNum, cmdHook)
+            ```
+
+            **表 1**  SHELLCMD\_ENTRY参数详解

+4.  输入Shell命令，有两种输入方式：
+    -   在串口工具中直接输入Shell命令。
+
+    -   在telnet工具中输入Shell命令（telnet使用方式详见[telnet](kernel-lite-small-shell-cmd-net-tel.md)）。

+## 基本概念<a name="section1179311337405"></a>
+
+从系统的角度看，线程是竞争系统资源的最小运行单元。线程可以使用或等待CPU、使用内存空间等系统资源，并独立于其它线程运行。
+
+OpenHarmony内核每个进程内的线程独立运行、独立调度，当前进程内线程的调度不受其它进程内线程的影响。
+
+OpenHarmony内核中的线程采用抢占式调度机制，同时支持时间片轮转调度和FIFO调度方式。
+
+OpenHarmony内核的线程一共有32个优先级\(0-31\)，最高优先级为0，最低优先级为31。
+
+当前进程内高优先级的线程可抢占当前进程内低优先级线程，当前进程内低优先级线程必须在当前进程内高优先级线程阻塞或结束后才能得到调度。
+
+**线程状态说明：**
+
+-   初始化（Init）：该线程正在被创建。
+
+-   就绪（Ready）：该线程在就绪列表中，等待CPU调度。
+
+-   运行（Running）：该线程正在运行。
+
+-   阻塞（Blocked）：该线程被阻塞挂起。Blocked状态包括：pending\(因为锁、事件、信号量等阻塞\)、suspended（主动pend）、delay\(延时阻塞\)、pendtime\(因为锁、事件、信号量时间等超时等待\)。
+
+-   退出（Exit）：该线程运行结束，等待父线程回收其控制块资源。
+
+
+**图 1**  线程状态迁移示意图<a name="fig15746193414436"></a>  
+![](figure/线程状态迁移示意图.png "线程状态迁移示意图")
+
+**线程状态迁移说明：**
+
+-   Init→Ready：
+
+    线程创建拿到控制块后为Init状态，处于线程初始化阶段，当线程初始化完成将线程插入调度队列，此时线程进入就绪状态。
+
+-   Ready→Running：
+
+    线程创建后进入就绪态，发生线程切换时，就绪列表中最高优先级的线程被执行，从而进入运行态，但此刻该线程会从就绪列表中删除。
+
+-   Running→Blocked：
+
+    正在运行的线程发生阻塞（挂起、延时、读信号量等）时，线程状态由运行态变成阻塞态，然后发生线程切换，运行就绪列表中剩余最高优先级线程。
+
+-   Blocked→Ready ：
+
+    阻塞的线程被恢复后（线程恢复、延时时间超时、读信号量超时或读到信号量等），此时被恢复的线程会被加入就绪列表，从而由阻塞态变成就绪态。
+
+-   Ready→Blocked：
+
+    线程也有可能在就绪态时被阻塞（挂起），此时线程状态会由就绪态转变为阻塞态，该线程从就绪列表中删除，不会参与线程调度，直到该线程被恢复。
+
+-   Running→Ready：
+
+    有更高优先级线程创建或者恢复后，会发生线程调度，此刻就绪列表中最高优先级线程变为运行态，那么原先运行的线程由运行态变为就绪态，并加入就绪列表中。
+
+-   Running→Exit：
+
+    运行中的线程运行结束，线程状态由运行态变为退出态。若未设置分离属性（PTHREAD\_CREATE\_DETACHED）的线程，运行结束后对外呈现的是Exit状态，即退出态。
+
+
+## 使用场景<a name="section44877547404"></a>
+
+线程创建后，用户态可以执行线程调度、挂起、恢复、延时等操作，同时也可以设置线程优先级和调度策略，获取线程优先级和调度策略。
+
+## 接口说明<a name="section2069477134115"></a>

+
+
+## 开发示例1<a name="section19369206113115"></a>
+
+以hi3516dv300开源开发板+ubuntu x86主机开发环境为例。
+
+### 场景1：版本级编译原生方式<a name="section1025111193220"></a>
+
+使用工程的全量编译命令，编译生成uImage内核镜像
+
+```
+./build.sh --product-name Hi3516DV300 # 编译hi3516dv300的uImage内核镜像
+```
+
+### 场景2：单独编译修改后的内核<a name="section17446652173211"></a>
+
+1.  准备工作
+
+    1.  按[开发板Patch使用指导](kernel-standard-patch.md)打入所需补丁。
+    2.  准备编译环境，可以使用开源arm clang/gcc编译器。
+
+    进入工程主目录配置环境变量：
+
+    ```
+    export PATH=`pwd`/prebuilts/clang/host/linux-x86/clang-r353983c/bin:`pwd`/prebuilts/gcc/linux-x86/arm/gcc-linaro-7.5.0-arm-linux-gnueabi/bin/:$PATH # 配置编译环境
+    MAKE_OPTIONES="ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- CC=clang HOSTCC=clang" # 使用工程项目自带的clang环境
+    ```
+
+2.  修改内核代码或内核config （OpenHarmony提供对应平台的defconfig供参考）。
+3.  创建编译目录及生成内核.config。
+
+    ```
+    make ${MAKE_OPTIONES} hi3516dv300_emmc_smp_hos_l2_defconfig # 使用自带的默认config 构建内核
+    ```
+
+4.  编译生成对应的内核Image。
+
+    ```
+    make ${MAKE_OPTIONES} -j32 uImage # 编译uImage内核镜像
+    ```
+
+

+# OpenHarmony开发板Patch使用指导<a name="ZH-CN_TOPIC_0000001081980461"></a>
+
+Patch文件位于工程项目源码路径：kernel/linux/patches/linux-4.19，存放特定芯片架构驱动补丁。
+
+如需使用特定芯片平台驱动的Patch，需要在内核仓代码完成对芯片平台驱动补丁合入。
+
+合入芯片平台驱动补丁，针对不同芯片平台合入对应的patch：
+
+以Hi3516dv300为例：
+
+```
+patch -p1 < device/hisilicon/hi3516dv300/sdk_linux/open_source/linux/hisi_linux-4.19_hos_l2.patch 
+```
+
+>![](../public_sys-resources/icon-notice.gif) **须知：** 
+>由于OpenHarmony的编译构建流程中会拷贝kernel/linux-4.19的代码环境后进行打补丁动作，在使用OpenHarmony的版本级编译命令前，需要kernel/linux-4.19保持原代码环境。

-## 基础概念<a name="section52691565235"></a>
-
-内存信息包括内存池大小、内存使用量、剩余内存大小、最大空闲内存、内存水线、内存节点数统计、碎片率等。
-
--   内存水线：即内存池的最大使用量，每次申请和释放时，都会更新水线值，实际业务可根据该值，优化内存池大小；
-
--   碎片率：衡量内存池的碎片化程度，碎片率高表现为内存池剩余内存很多，但是最大空闲内存块很小，可以用公式（fragment=100-最大空闲内存块大小/剩余内存大小）来度量；
-
--   其他参数：通过调用接口（详见[内存管理](内存管理.md)章节接口说明），扫描内存池的节点信息，统计出相关信息。
-
-## 功能配置<a name="section470611682411"></a>
-
-LOSCFG\_MEM\_WATERLINE：开关宏，默认打开；若关闭这个功能，在target\_config.h中将这个宏定义为0。如需获取内存水线，需要打开该配置。
-
-## 开发指导<a name="section9368374243"></a>

-### 开发流程<a name="section679912407257"></a>
-
-关键结构体介绍：
-
-```
-typedef struct {
-    UINT32 totalUsedSize;       // 内存池的内存使用量
-    UINT32 totalFreeSize;       // 内存池的剩余内存大小
-    UINT32 maxFreeNodeSize;     // 内存池的最大空闲内存块大小
-    UINT32 usedNodeNum;         // 内存池的非空闲内存块个数
-    UINT32 freeNodeNum;         // 内存池的空闲内存块个数
-#if (LOSCFG_MEM_WATERLINE == 1) // 默认打开，如需关闭，在target_config.h中将该宏设置为0
-    UINT32 usageWaterLine;      // 内存池的水线值
-#endif
-} LOS_MEM_POOL_STATUS;
-```
-
--   内存水线获取：调用LOS\_MemInfoGet接口，第1个参数是内存池首地址，第2个参数是LOS\_MEM\_POOL\_STATUS类型的句柄，其中字段usageWaterLine即水线值。
-
--   内存碎片率计算：同样调用LOS\_MemInfoGet接口，可以获取内存池的剩余内存大小和最大空闲内存块大小，然后根据公式（fragment=100-最大空闲内存块大小/剩余内存大小）得出此时的动态内存池碎片率。
-

-
-1.创建一个监控线程，用于获取内存池的信息；
-
-2.调用LOS\_MemInfoGet接口，获取内存池的基础信息；
-
-3.利用公式算出使用率及碎片率。
-
-### 示例代码<a name="section165277971315"></a>
-
-代码实现如下：
-
-```
-#include <stdio.h>
-#include <string.h>

-    unsigned char fragment = 100 - poolStatus.maxFreeNodeSize * 100 / poolStatus.totalFreeSize;
-    /* 算出内存池当前的使用率百分比 */
-    unsigned char usage = LOS_MemTotalUsedGet(pool) * 100 / LOS_MemPoolSizeGet(pool);
-    printf("usage = %d, fragment = %d, maxFreeSize = %d, totalFreeSize = %d, waterLine = %d\n", usage, fragment, poolStatus.maxFreeNodeSize, 
-           poolStatus.totalFreeSize, poolStatus.usageWaterLine);

-{
-    unsigned int ret;
-    unsigned int taskID;
-    TSK_INIT_PARAM_S taskStatus = {0};
-    taskStatus.pfnTaskEntry = (TSK_ENTRY_FUNC)MemInfoTaskFunc;
-    taskStatus.uwStackSize  = 0x1000;
-    taskStatus.pcName       = "memInfo";
-    taskStatus.usTaskPrio   = 10;
-    ret = LOS_TaskCreate(&taskID, &taskStatus);
-    if (ret != LOS_OK) {
-        printf("task create failed\n");
-        return -1;
-    }
-    return 0;

-编译运行输出的结果如下：
-
-```
-usage = 22, fragment = 3, maxFreeSize = 49056, totalFreeSize = 50132, waterLine = 1414

-## 基础概念<a name="section1026719436293"></a>
-
-内存泄漏检测机制作为内核的可选功能，用于辅助定位动态内存泄漏问题。开启该功能，动态内存机制会自动记录申请内存时的函数调用关系（下文简称LR）。如果出现泄漏，就可以利用这些记录的信息，找到内存申请的地方，方便进一步确认。
-
-## 功能配置<a name="section13991354162914"></a>
-
-1.  LOSCFG\_MEM\_LEAKCHECK：开关宏，默认关闭；若打开这个功能，在target\_config.h中将这个宏定义为1。
-2.  LOSCFG\_MEM\_RECORD\_LR\_CNT：记录的LR层数，默认3层；每层LR消耗sizeof\(void \*\)字节数的内存。
-3.  LOSCFG\_MEM\_OMIT\_LR\_CNT：忽略的LR层数，默认4层，即从调用LOS\_MemAlloc的函数开始记录，可根据实际情况调整。为啥需要这个配置？有3点原因如下：
-    -   LOS\_MemAlloc接口内部也有函数调用；
-    -   外部可能对LOS\_MemAlloc接口有封装；
-    -   LOSCFG\_MEM\_RECORD\_LR\_CNT 配置的LR层数有限；
-
-
-正确配置这个宏，将无效的LR层数忽略，就可以记录有效的LR层数，节省内存消耗。
-
-## 开发指导<a name="section95828159308"></a>
-
-### 开发流程<a name="section369844416304"></a>
-
-该调测功能可以分析关键的代码逻辑中是否存在内存泄漏。开启这个功能，每次申请内存时，会记录LR信息。在需要检测的代码段前后，调用LOS\_MemUsedNodeShow接口，每次都会打印指定内存池已使用的全部节点信息，对比前后两次的节点信息，新增的节点信息就是疑似泄漏的内存节点。通过LR，可以找到具体申请的代码位置，进一步确认是否泄漏。
-
-调用LOS\_MemUsedNodeShow接口输出的节点信息格式如下：每1行为一个节点信息；第1列为节点地址，可以根据这个地址，使用GDB等手段查看节点完整信息；第2列为节点的大小，等于节点头大小+数据域大小；第3\~5列为函数调用关系LR地址，可以根据这个值，结合汇编文件，查看该节点具体申请的位置。

-### 编程实例<a name="section460801313313"></a>
-
-本实例实现如下功能：构建内存泄漏代码段。
-
-1.  调用LOS\_MemUsedNodeShow接口，输出全部节点信息打印；
-2.  申请内存，但没有释放，模拟内存泄漏；
-3.  再次调用LOS\_MemUsedNodeShow接口，输出全部节点信息打印；
-4.  将两次log进行对比，得出泄漏的节点信息；
-5.  通过LR地址，找出泄漏的代码位置；
-
-### 示例代码<a name="section96539275311"></a>
-
-代码实现如下：
-
-```
-#include <stdio.h>
-#include <string.h>
-#include "los_memory.h"
-#include "los_config.h"
-
-void MemLeakTest(void)
-{
-    LOS_MemUsedNodeShow(LOSCFG_SYS_HEAP_ADDR);
-    void *ptr1 = LOS_MemAlloc(LOSCFG_SYS_HEAP_ADDR, 8);
-    void *ptr2 = LOS_MemAlloc(LOSCFG_SYS_HEAP_ADDR, 8);
-    LOS_MemUsedNodeShow(LOSCFG_SYS_HEAP_ADDR);
-}
-```

-```
-
-其中，通过查找0x080041ee，就可以发现该内存节点是在MemLeakTest接口里申请的且是没有释放的。

-
-动态内存管理，即在内存资源充足的情况下，根据用户需求，从系统配置的一块比较大的连续内存（内存池，也是堆内存）中分配任意大小的内存块。当用户不需要该内存块时，又可以释放回系统供下一次使用。与静态内存相比，动态内存管理的优点是按需分配，缺点是内存池中容易出现碎片。
-
-OpenHarmony LiteOS-M动态内存在TLSF算法的基础上，对区间的划分进行了优化，获得更优的性能，降低了碎片率。动态内存核心算法框图如下：
-
-**图 1**  动态内存核心算法<a name="fig14558185217397"></a>  
-![](figures/动态内存核心算法.png "动态内存核心算法")
-
-根据空闲内存块的大小，使用多个空闲链表来管理。根据内存空闲块大小分为两个部分：\[4, 127\]和\[2<sup>7</sup>, 2<sup>31</sup>\]，如上图size class所示：
-
-1.  对\[4,127\]区间的内存进行等分，如上图绿色部分所示，分为31个小区间，每个小区间对应内存块大小为4字节的倍数。每个小区间对应一个空闲内存链表和用于标记对应空闲内存链表是否为空的一个比特位，值为1时，空闲链表非空。\[4,127\]区间的31个小区间内存对应31个比特位进行标记链表是否为空。
-2.  大于127字节的空闲内存块，按照2的次幂区间大小进行空闲链表管理。总共分为24个小区间，每个小区间又等分为8个二级小区间，见上图蓝色的Size Class和Size SubClass部分。每个二级小区间对应一个空闲链表和用于标记对应空闲内存链表是否为空的一个比特位。总共24\*8=192个二级小区间，对应192个空闲链表和192个比特位进行标记链表是否为空。
-
-例如，当有40字节的空闲内存需要插入空闲链表时，对应小区间\[40,43\]，第10个空闲链表，位图标记的第10比特位。把40字节的空闲内存挂载第10个空闲链表上，并判断是否需要更新位图标记。当需要申请40字节的内存时，根据位图标记获取存在满足申请大小的内存块的空闲链表，从空闲链表上获取空闲内存节点。如果分配的节点大于需要申请的内存大小，进行分割节点操作，剩余的节点重新挂载到相应的空闲链表上。当有580字节的空闲内存需要插入空闲链表时，对应二级小区间\[2^9,2^9+2^6\]，第31+2\*8=47个空闲链表，并使用位图的第47个比特位来标记链表是否为空。把580字节的空闲内存挂载第47个空闲链表上，并判断是否需要更新位图标记。当需要申请580字节的内存时，根据位图标记获取存在满足申请大小的内存块的空闲链表，从空闲链表上获取空闲内存节点。如果分配的节点大于需要申请的内存大小，进行分割节点操作，剩余的节点重新挂载到相应的空闲链表上。如果对应的空闲链表为空，则向更大的内存区间去查询是否有满足条件的空闲链表，实际计算时，会一次性查找到满足申请大小的空闲链表。
-
-内存管理结构如下图所示：

-![](figures/动态内存管理结构图.png "动态内存管理结构图")
-
--   内存池池头部分
-
-    内存池池头部分包含内存池信息、位图标记数组和空闲链表数组。内存池信息包含内存池起始地址及堆区域总大小，内存池属性。位图标记数组有7个32位无符号整数组成，每个比特位标记对应的空闲链表是否挂载空闲内存块节点。空闲内存链表包含223个空闲内存头节点信息，每个空闲内存头节点信息维护内存节点头和空闲链表中的前驱、后继空闲内存节点。
-
--   内存池节点部分
-
-    包含3种类型节点：未使用空闲内存节点，已使用内存节点和尾节点。每个内存节点维护一个前序指针，指向内存池中上一个内存节点，还维护内存节点的大小和使用标记。空闲内存节点和已使用内存节点后面的内存区域是数据域，尾节点没有数据域。

-## 开发指导<a name="section7921151015814"></a>
-
-### 使用场景<a name="section326917198583"></a>
-
-动态内存管理的主要工作是动态分配并管理用户申请到的内存区间。动态内存管理主要用于用户需要使用大小不等的内存块的场景，当用户需要使用内存时，可以通过操作系统的动态内存申请函数索取指定大小的内存块，一旦使用完毕，通过动态内存释放函数归还所占用内存，使之可以重复使用。

->-   由于动态内存管理需要管理控制块数据结构来管理内存，这些数据结构会额外消耗内存，故实际用户可使用内存总量小于配置项OS\_SYS\_MEM\_SIZE的大小。
->-   对齐分配内存接口LOS\_MemAllocAlign/LOS\_MemMallocAlign因为要进行地址对齐，可能会额外消耗部分内存，故存在一些遗失内存，当系统释放该对齐内存时，同时回收由于对齐导致的遗失内存。
-
-### 开发流程<a name="section07271773592"></a>
-
-本节介绍使用动态内存的典型场景开发流程。
-
-1.  初始化LOS\_MemInit。
-
-    初始一个内存池后生成一个内存池控制头、尾节点EndNode，剩余的内存被标记为FreeNode内存节点。注：EndNode作为内存池末尾的节点，size为0。
-
-
-1.  申请任意大小的动态内存LOS\_MemAlloc。
-
-    判断动态内存池中是否存在大于申请量大小的空闲内存块空间，若存在，则划出一块内存块，以指针形式返回，若不存在，返回NULL。如果空闲内存块大于申请量，需要对内存块进行分割，剩余的部分作为空闲内存块挂载到空闲内存链表上。
-
-
-1.  释放动态内存LOS\_MemFree。
-
-    回收内存块，供下一次使用。调用LOS\_MemFree释放内存块，则会回收内存块，并且将其标记为FreeNode。在回收内存块时，相邻的FreeNode会自动合并。
-
-
-### 编程实例<a name="section84931234145913"></a>
-
-本实例执行以下步骤：
-
-1.  初始化一个动态内存池。
-2.  从动态内存池中申请一个内存块。
-3.  在内存块中存放一个数据。
-4.  打印出内存块中的数据。
-5.  释放该内存块。
-
-示例代码如下：
-
-```
-#include "los_memory.h"
-
-VOID Example_DynMem(VOID)
-{
-    UINT32 *mem = NULL;
-    UINT32 ret;
-
-    /*初始化内存池*/
-    ret = LOS_MemInit(g_testPool, TEST_POOL_SIZE);
-    if (LOS_OK  == ret) {
-        printf("Mem init success!\n");
-    } else {
-        printf("Mem init failed!\n");
-        return;
-    }
-
-    /*分配内存*/
-    mem = (UINT32 *)LOS_MemAlloc(g_testPool, 4);
-    if (NULL == mem) {
-        printf("Mem alloc failed!\n");
-        return;
-    }
-    printf("Mem alloc success!\n");
-
-    /*赋值*/
-    *mem = 828;
-    printf("*mem = %d\n", *mem);
-
-    /*释放内存*/
-    ret = LOS_MemFree(g_testPool, mem);
-    if (LOS_OK == ret) {
-        printf("Mem free success!\n");
-    } else {
-        printf("Mem free failed!\n");
-    }
-
-    return;
-}
-```
-
-### 结果验证<a name="section165233233917"></a>
-
-输出结果如下：
-
-```
-Mem init success!
-Mem alloc success!
-*mem = 828
-Mem free success!
-```

-## 基本概念<a name="section1990715203418"></a>
-
-双向链表是指含有往前和往后两个方向的链表，即每个结点中除存放下一个节点指针外，还增加一个指向前一个节点的指针。其头指针head是唯一确定的。
-
-从双向链表中的任意一个结点开始，都可以很方便地访问它的前驱结点和后继结点，这种数据结构形式使得双向链表在查找时更加方便，特别是大量数据的遍历。由于双向链表具有对称性，能方便地完成各种插入、删除等操作，但需要注意前后方向的操作。
-
-## 功能说明<a name="section848334511411"></a>
-
-双向链表模块为用户提供下面几种功能，接口详细信息可以查看API参考。

-双向链表的典型开发流程：
-
-1.  调用LOS\_ListInit/LOS\_DL\_LIST\_HEAD初始双向链表。
-2.  调用LOS\_ListAdd向链表插入节点。
-3.  调用LOS\_ListTailInsert向链表尾部插入节点。
-4.  调用LOS\_ListDelete删除指定节点。
-5.  调用LOS\_ListEmpty判断链表是否为空。
-6.  调用LOS\_ListDelInit删除指定节点并以此节点初始化链表。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   需要注意节点指针前后方向的操作。
->-   链表操作接口，为底层接口，不对入参进行判空，需要使用者确保传参合法。
->-   如果链表节点的内存是动态申请的，删除节点时，要注意释放内存。

-
-信号量（Semaphore）是一种实现任务间通信的机制，可以实现任务间同步或共享资源的互斥访问。
-
-一个信号量的数据结构中，通常有一个计数值，用于对有效资源数的计数，表示剩下的可被使用的共享资源数，其值的含义分两种情况：
-
--   0，表示该信号量当前不可获取，因此可能存在正在等待该信号量的任务。
--   正值，表示该信号量当前可被获取。
-
-以同步为目的的信号量和以互斥为目的的信号量在使用上有如下不同：
-
--   用作互斥时，初始信号量计数值不为0，表示可用的共享资源个数。在需要使用共享资源前，先获取信号量，然后使用一个共享资源，使用完毕后释放信号量。这样在共享资源被取完，即信号量计数减至0时，其他需要获取信号量的任务将被阻塞，从而保证了共享资源的互斥访问。另外，当共享资源数为1时，建议使用二值信号量，一种类似于互斥锁的机制。
--   用作同步时，初始信号量计数值为0。任务1获取信号量而阻塞，直到任务2或者某中断释放信号量，任务1才得以进入Ready或Running态，从而达到了任务间的同步。

-
-### 信号量运作原理<a name="section139726510491"></a>
-
-信号量初始化，为配置的N个信号量申请内存（N值可以由用户自行配置，通过LOSCFG\_BASE\_IPC\_SEM\_LIMIT宏实现），并把所有信号量初始化成未使用，加入到未使用链表中供系统使用。
-
-信号量创建，从未使用的信号量链表中获取一个信号量，并设定初值。
-
-信号量申请，若其计数器值大于0，则直接减1返回成功。否则任务阻塞，等待其它任务释放该信号量，等待的超时时间可设定。当任务被一个信号量阻塞时，将该任务挂到信号量等待任务队列的队尾。
-
-信号量释放，若没有任务等待该信号量，则直接将计数器加1返回。否则唤醒该信号量等待任务队列上的第一个任务。
-
-信号量删除，将正在使用的信号量置为未使用信号量，并挂回到未使用链表。
-
-信号量允许多个任务在同一时刻访问共享资源，但会限制同一时刻访问此资源的最大任务数目。当访问资源的任务数达到该资源允许的最大数量时，会阻塞其他试图获取该资源的任务，直到有任务释放该信号量。

-
-从系统角度看，任务是竞争系统资源的最小运行单元。任务可以使用或等待CPU、使用内存空间等系统资源，并独立于其它任务运行。
-
-OpenHarmony LiteOS-M的任务模块可以给用户提供多个任务，实现任务间的切换，帮助用户管理业务程序流程。任务模块具有如下特性：
-
--   支持多任务。
--   一个任务表示一个线程。
--   抢占式调度机制，高优先级的任务可打断低优先级任务，低优先级任务必须在高优先级任务阻塞或结束后才能得到调度。
--   相同优先级任务支持时间片轮转调度方式。
--   共有32个优先级\[0-31\]，最高优先级为0，最低优先级为31。
-
-## 任务相关概念<a name="section673132352511"></a>
-
-**任务状态**
-
-任务有多种运行状态。系统初始化完成后，创建的任务就可以在系统中竞争一定的资源，由内核进行调度。
-
-任务状态通常分为以下四种：
-
--   就绪（Ready）：该任务在就绪队列中，只等待CPU。
--   运行（Running）：该任务正在执行。
--   阻塞（Blocked）：该任务不在就绪队列中。包含任务被挂起（suspend状态）、任务被延时（delay状态）、任务正在等待信号量、读写队列或者等待事件等。
--   退出态（Dead）：该任务运行结束，等待系统回收资源。
-
-**任务状态迁移**
-
-**图 1**  任务状态示意图<a name="fig65504113015"></a>  
-![](figures/任务状态示意图.png "任务状态示意图")
-
-**任务状态迁移说明：**
-
--   就绪态→运行态
-
-    任务创建后进入就绪态，发生任务切换时，就绪队列中最高优先级的任务被执行，从而进入运行态，同时该任务从就绪队列中移出。
-
--   运行态→阻塞态
-
-    正在运行的任务发生阻塞（挂起、延时、读信号量等）时，该任务会从就绪队列中删除，任务状态由运行态变成阻塞态，然后发生任务切换，运行就绪队列中最高优先级任务。
-
--   阻塞态→就绪态（阻塞态→运行态）
-
-    阻塞的任务被恢复后（任务恢复、延时时间超时、读信号量超时或读到信号量等），此时被恢复的任务会被加入就绪队列，从而由阻塞态变成就绪态；此时如果被恢复任务的优先级高于正在运行任务的优先级，则会发生任务切换，该任务由就绪态变成运行态。
-
--   就绪态→阻塞态
-
-    任务也有可能在就绪态时被阻塞（挂起），此时任务状态由就绪态变为阻塞态，该任务从就绪队列中删除，不会参与任务调度，直到该任务被恢复。
-
--   运行态→就绪态
-
-    有更高优先级任务创建或者恢复后，会发生任务调度，此刻就绪队列中最高优先级任务变为运行态，那么原先运行的任务由运行态变为就绪态，依然在就绪队列中。
-
--   运行态→退出态
-
-    运行中的任务运行结束，任务状态由运行态变为退出态。退出态包含任务运行结束的正常退出状态以及Invalid状态。例如，任务运行结束但是没有自删除，对外呈现的就是Invalid状态，即退出态。
-
--   阻塞态→退出态
-
-    阻塞的任务调用删除接口，任务状态由阻塞态变为退出态。
-
-
-**任务ID**
-
-任务ID，在任务创建时通过参数返回给用户，是任务的重要标识。系统中的ID号是唯一的。用户可以通过任务ID对指定任务进行任务挂起、任务恢复、查询任务名等操作。
-
-**任务优先级**
-
-优先级表示任务执行的优先顺序。任务的优先级决定了在发生任务切换时即将要执行的任务，就绪队列中最高优先级的任务将得到执行。
-
-**任务入口函数**
-
-新任务得到调度后将执行的函数。该函数由用户实现，在任务创建时，通过任务创建结构体设置。
-
-**任务栈**
-
-每个任务都拥有一个独立的栈空间，我们称为任务栈。栈空间里保存的信息包含局部变量、寄存器、函数参数、函数返回地址等。
-
-**任务上下文**
-
-任务在运行过程中使用的一些资源，如寄存器等，称为任务上下文。当这个任务挂起时，其他任务继续执行，可能会修改寄存器等资源中的值。如果任务切换时没有保存任务上下文，可能会导致任务恢复后出现未知错误。因此在任务切换时会将切出任务的任务上下文信息，保存在自身的任务栈中，以便任务恢复后，从栈空间中恢复挂起时的上下文信息，从而继续执行挂起时被打断的代码。
-
-**任务控制块TCB**
-
-每个任务都含有一个任务控制块\(TCB\)。TCB包含了任务上下文栈指针（stack pointer）、任务状态、任务优先级、任务ID、任务名、任务栈大小等信息。TCB可以反映出每个任务运行情况。
-
-**任务切换**
-
-任务切换包含获取就绪队列中最高优先级任务、切出任务上下文保存、切入任务上下文恢复等动作。
-
-## 任务运行机制<a name="section176294469251"></a>
-
-用户创建任务时，系统会初始化任务栈，预置上下文。此外，系统还会将“任务入口函数”地址放在相应位置。这样在任务第一次启动进入运行态时，将会执行“任务入口函数”。

-LittleFS主要用在微控制器和flash上，是一种嵌入式文件系统，具有如下3个特点：
-
-1.  掉电恢复
-
-    在写入时即使复位或者掉电也可以恢复到上一个正确的状态。
-
-2.  擦写均衡
-
-    有效延长flash的使用寿命。
-
-3.  有限的RAM/ROM
-
-    节省ROM和RAM空间。
-
-
-## 运行机制<a name="section10284121317365"></a>
-
-最经典的掉电保护方法有两种，一种是使用日志，一种是通过COW方式。lfs结合了两种方法，并优化了两种方案的缺点，提供了一套掉电保护策略
-
-### 日志方式<a name="section13804114513361"></a>
-
-![](figures/zh-cn_image_0000001124310992.png)
-
-具体步骤为：
-
-1.  写入数据之前，先在日志区存储开始标志，记录要写入的数据位置和大小；
-2.  待写入的数据写入日志区；
-3.  待写入的数据写入数据区；
-4.  写入完成之后，在日志区记录结束标志。
-
-模拟掉电场景：
-
-1.  步骤1完成，步骤2没有完成；重启之后，保持原来的数据，日志无效；
-2.  步骤1，2完成了，步骤3没有完成，尝试把步骤2的数据写入到数据区；
-3.  步骤1，2，3完成了，步骤4没有完成，同样尝试把步骤2的数据写入到数据区；
-
-### Cow机制<a name="section172771130193610"></a>
-
-![](figures/zh-cn_image_0000001170790681.png)
-
-具体步骤为：
-
-1.  想更新节点F的数据，先申请一个新的节点，把F的旧数据拷贝过去，然后更新新的数据；
-2.  把父节点的指针指向新的节点，去掉旧节点的指针。
-
-模拟掉电场景：
-
-步骤1完成了，步骤2没有完成，则使用旧的数据，新的节点变成孤儿节点。
-
-### lfs掉电保护<a name="section42941021173614"></a>
-
-fs结合了日志方式和COW机制两种方式进行掉电保护，并且优化了两种方案。
-
-前面谈过文件系统三要素，超级块，inode，以及数据。对应lfs来说，他把超级块以及inode通过日志的方式存储，两种采用统一的存储结构，后文称两者为元数据；普通数据则采用cow的方式存储，采用czt逆序链表的方式。
-
-![](figures/zh-cn_image_0000001124307264.png)
-
-**元数据的存储**
-
-![](figures/zh-cn_image_0000001124147160.png)
-
-元数据（对应root，dir）采用双block的方式存储，互为备份，每个block都有一个revision序号，值越大，表示block的数据越新，每个block默认可以存储最多0xff个文件的数据，如果超过这个值，则需要compact（压缩）。
-
-Compact是干什么呢？ 即当数据的大小大于某个值的时候，把数据整合，剔除同一个id的旧的数据，然后写入到备份block里面。
-
-**普通数据的存储**
-
-Lfs的数据采用链表的方式逆向管理。
-
-![](figures/zh-cn_image_0000001124306828.png)
-
-1.  采用逆向的指针，这样常规的追加数据，不需要额外的开销来重新建立所有的索引；
-2.  每个偶数block有多个指针，指向更远的数据，这样可以在检索的时候加快速度。

-事件（Event）是一种任务间的通信机制，可用于任务间的同步操作。事件的特点是：
-
--   任务间的事件同步，可以一对多，也可以多对多。一对多表示一个任务可以等待多个事件，多对多表示多个任务可以等待多个事件。但是一次写事件最多触发一个任务从阻塞中醒来。

-```
-
-### 事件运作原理<a name="section187761153144617"></a>
-
-**事件初始化：**会创建一个事件控制块，该控制块维护一个已处理的事件集合，以及等待特定事件的任务链表。
-
-**写事件：**会向事件控制块写入指定的事件，事件控制块更新事件集合，并遍历任务链表，根据任务等待具体条件满足情况决定是否唤醒相关任务。
-
-**读事件：**如果读取的事件已存在时，会直接同步返回。其他情况会根据超时时间以及事件触发情况，来决定返回时机：等待的事件条件在超时时间耗尽之前到达，阻塞任务会被直接唤醒，否则超时时间耗尽该任务才会被唤醒。
-
-读事件条件满足与否取决于入参eventMask和mode，eventMask即需要关注的事件。mode是具体处理方式，分以下三种情况：
-
-LOS\_WAITMODE\_AND：表示eventMask中所有事件都发生时，才返回。
-
-LOS\_WAITMODE\_OR：表示eventMask中任何事件发生时，就返回。
-
-LOS\_WAITMODE\_CLR：事件读取成功后，对应读取到的事件会被清零。需要配合LOS\_WAITMODE\_AND或者LOS\_WAITMODE\_OR来使用。
-
-**事件清零：**根据指定掩码，去对事件控制块的事件集合进行清零操作。当掩码为0时，表示将事件集合全部清零。当掩码为0xffff时，表示不清除任何事件，保持事件集合原状。
-
-**事件销毁：**销毁指定的事件控制块。

-互斥锁又称互斥型信号量，是一种特殊的二值性信号量，用于实现对共享资源的独占式处理。
-
-任意时刻互斥锁的状态只有两种，开锁或闭锁。当有任务持有时，互斥锁处于闭锁状态，这个任务获得该互斥锁的所有权。当该任务释放它时，该互斥锁被开锁，任务失去该互斥锁的所有权。当一个任务持有互斥锁时，其他任务将不能再对该互斥锁进行开锁或持有。
-
-多任务环境下往往存在多个任务竞争同一共享资源的应用场景，互斥锁可被用于对共享资源的保护从而实现独占式访问。另外互斥锁可以解决信号量存在的优先级翻转问题。

-
-多任务环境下会存在多个任务访问同一公共资源的场景，而有些公共资源是非共享的，需要任务进行独占式处理。互斥锁怎样来避免这种冲突呢？
-
-用互斥锁处理非共享资源的同步访问时，如果有任务访问该资源，则互斥锁为加锁状态。此时其他任务如果想访问这个公共资源则会被阻塞，直到互斥锁被持有该锁的任务释放后，其他任务才能重新访问该公共资源，此时互斥锁再次上锁，如此确保同一时刻只有一个任务正在访问这个公共资源，保证了公共资源操作的完整性。

-队列又称消息队列，是一种常用于任务间通信的数据结构。队列接收来自任务或中断的不固定长度消息，并根据不同的接口确定传递的消息是否存放在队列空间中。
-
-任务能够从队列里面读取消息，当队列中的消息为空时，挂起读取任务；当队列中有新消息时，挂起的读取任务被唤醒并处理新消息。任务也能够往队列里写入消息，当队列已经写满消息时，挂起写入任务；当队列中有空闲消息节点时，挂起的写入任务被唤醒并写入消息。
-
-可以通过调整读队列和写队列的超时时间来调整读写接口的阻塞模式，如果将读队列和写队列的超时时间设置为0，就不会挂起任务，接口会直接返回，这就是非阻塞模式。反之，如果将都队列和写队列的超时时间设置为大于0的时间，就会以阻塞模式运行。
-
-消息队列提供了异步处理机制，允许将一个消息放入队列，但不立即处理。同时队列还有缓冲消息的作用，可以使用队列实现任务异步通信，队列具有如下特性：
-
--   消息以先进先出的方式排队，支持异步读写。
--   读队列和写队列都支持超时机制。
--   每读取一条消息，就会将该消息节点设置为空闲。
--   发送消息类型由通信双方约定，可以允许不同长度（不超过队列的消息节点大小）的消息。
--   一个任务能够从任意一个消息队列接收和发送消息。
--   多个任务能够从同一个消息队列接收和发送消息。
--   创建队列时所需的队列空间，接口内系统自行动态申请内存。

-    LOS_DL_LIST memList;                         /* 内存块链表 */
-} LosQueueCB;

-
-每个队列控制块中都含有队列状态，表示该队列的使用情况：
-
--   OS\_QUEUE\_UNUSED：队列未被使用。
--   OS\_QUEUE\_INUSED：队列被使用中。
-
-### 队列运作原理<a name="section15384012164811"></a>
-
--   创建队列时，创建队列成功会返回队列ID。
--   在队列控制块中维护着一个消息头节点位置Head和一个消息尾节点位置Tail，用于表示当前队列中消息的存储情况。Head表示队列中被占用的消息节点的起始位置。Tail表示被占用的消息节点的结束位置，也是空闲消息节点的起始位置。队列刚创建时，Head和Tail均指向队列起始位置。
--   写队列时，根据readWriteableCnt\[1\]判断队列是否可以写入，不能对已满（readWriteableCnt\[1\]为0）队列进行写操作。写队列支持两种写入方式：向队列尾节点写入，也可以向队列头节点写入。尾节点写入时，根据Tail找到起始空闲消息节点作为数据写入对象，如果Tail已经指向队列尾部则采用回卷方式。头节点写入时，将Head的前一个节点作为数据写入对象，如果Head指向队列起始位置则采用回卷方式。
--   读队列时，根据readWriteableCnt\[0\]判断队列是否有消息需要读取，对全部空闲（readWriteableCnt\[0\]为0）队列进行读操作会引起任务挂起。如果队列可以读取消息，则根据Head找到最先写入队列的消息节点进行读取。如果Head已经指向队列尾部则采用回卷方式。
--   删除队列时，根据队列ID找到对应队列，把队列状态置为未使用，把队列控制块置为初始状态，并释放队列所占内存。

-## 开发流程<a name="section783435801510"></a>
-
-1.  用LOS\_QueueCreate创建队列。创建成功后，可以得到队列ID。
-2.  通过LOS\_QueueWrite或者LOS\_QueueWriteCopy写队列。
-3.  通过LOS\_QueueRead或者LOS\_QueueReadCopy读队列。
-4.  通过LOS\_QueueInfoGet获取队列信息。
-5.  通过LOS\_QueueDelete删除队列。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   系统支持的最大队列数是指：整个系统的队列资源总个数，而非用户能使用的个数。例如：系统软件定时器多占用一个队列资源，那么用户能使用的队列资源就会减少一个。
->-   创建队列时传入的队列名和flags暂时未使用，作为以后的预留参数。
->-   队列接口函数中的入参timeOut是相对时间。
->-   LOS\_QueueReadCopy和LOS\_QueueWriteCopy及LOS\_QueueWriteHeadCopy是一组接口，LOS\_QueueRead和LOS\_QueueWrite及LOS\_QueueWriteHead是一组接口，每组接口需要配套使用。
->-   鉴于LOS\_QueueWrite和LOS\_QueueWriteHead和LOS\_QueueRead这组接口实际操作的是数据地址，用户必须保证调用LOS\_QueueRead获取到的指针所指向的内存区域在读队列期间没有被异常修改或释放，否则可能导致不可预知的后果。
->-   鉴于LOS\_QueueWrite和LOS\_QueueWriteHead和LOS\_QueueRead这组接口实际操作的是数据地址，也就意味着实际写和读的消息长度仅仅是一个指针数据，因此用户使用这组接口之前，需确保创建队列时的消息节点大小，为一个指针的长度，避免不必要的浪费和读取失败。

-1.  通过LOS\_TaskCreate创建任务1和任务2。
-2.  通过LOS\_QueueCreate创建一个消息队列。
-3.  在任务1 SendEntry中发送消息。
-4.  在任务2 RecvEntry中接收消息。

-1.  创建信号量LOS\_SemCreate，若要创建二值信号量则调用LOS\_BinarySemCreate。
-2.  申请信号量LOS\_SemPend。
-3.  释放信号量LOS\_SemPost。
-4.  删除信号量LOS\_SemDelete。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->由于中断不能被阻塞，因此不能在中断中使用阻塞模式申请信号量。

-## 编程实例<a name="section460018317164"></a>
-
-### 实例描述<a name="section22061718111412"></a>
-
-本实例实现如下功能：
-
-1.  测试任务ExampleSem创建一个信号量，锁任务调度，创建两个任务ExampleSemTask1、ExampleSemTask2, ExampleSemTask2优先级高于ExampleSemTask1，两个任务中申请同一信号量，解锁任务调度后两任务阻塞，测试任务ExampleSem释放信号量。
-2.  ExampleSemTask2得到信号量，被调度，然后任务休眠20Tick，ExampleSemTask2延迟，ExampleSemTask1被唤醒。
-3.  ExampleSemTask1定时阻塞模式申请信号量，等待时间为10Tick，因信号量仍被ExampleSemTask2持有，ExampleSemTask1挂起，10Tick后仍未得到信号量，ExampleSemTask1被唤醒，试图以永久阻塞模式申请信号量，ExampleSemTask1挂起。
-4.  20Tick后ExampleSemTask2唤醒， 释放信号量后，ExampleSemTask1得到信号量被调度运行，最后释放信号量。
-5.  ExampleSemTask1执行完，40Tick后任务ExampleSem被唤醒，执行删除信号量。

-时间管理的典型开发流程：
-
-1.  根据实际需求，完成板级配置适配，并配置系统主时钟频率OS\_SYS\_CLOCK（单位Hz）和LOSCFG\_BASE\_CORE\_TICK\_PER\_SECOND。OS\_SYS\_CLOCK的默认值基于硬件平台配置。
-2.  调用时钟转换/统计接口。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   时间管理不是单独的功能模块，依赖于OS\_SYS\_CLOCK和LOSCFG\_BASE\_CORE\_TICK\_PER\_SECOND两个配置选项。
->-   系统的Tick数在关中断的情况下不进行计数，故系统Tick数不能作为准确时间使用。
->-   配置选项维护在开发板工程的文件target\_config.h。

-
-在下面的例子中，介绍了时间管理的基本方法，包括：
-
-1.  时间转换：将毫秒数转换为Tick数，或将Tick数转换为毫秒数。
-2.  时间统计：每Tick的Cycle数、自系统启动以来的Tick数和延迟后的Tick数。
-
-### 示例代码<a name="section321653551711"></a>
-
-前提条件：
-
--   使用每秒的Tick数LOSCFG\_BASE\_CORE\_TICK\_PER\_SECOND的默认值100。
--   配好OS\_SYS\_CLOCK系统主时钟频率。
-
-时间转换：
-
-```
-VOID Example_TransformTime(VOID)
-{
-    UINT32 ms;
-    UINT32 tick;
-
-    tick = LOS_MS2Tick(10000);    // 10000ms转换为tick
-    dprintf("tick = %d \n", tick);
-    ms = LOS_Tick2MS(100);        // 100tick转换为ms
-    dprintf("ms = %d \n", ms);
-}
-```
-
-时间统计和时间延迟：
-
-```
-VOID Example_GetTime(VOID)
-{
-    UINT32 cyclePerTick;
-    UINT64 tickCount;
-
-    cyclePerTick  = LOS_CyclePerTickGet();
-    if(0 != cyclePerTick) {
-        dprintf("LOS_CyclePerTickGet = %d \n", cyclePerTick);
-    }
-
-    tickCount = LOS_TickCountGet();
-    if(0 != tickCount) {
-        dprintf("LOS_TickCountGet = %d \n", (UINT32)tickCount);

-## 开发流程<a name="section783435801510"></a>
-
-软件定时器的典型开发流程：
-
-1.  配置软件定时器。
-    -   确认配置项LOSCFG\_BASE\_CORE\_SWTMR和LOSCFG\_BASE\_IPC\_QUEUE为1打开状态；
-    -   配置LOSCFG\_BASE\_CORE\_SWTMR\_LIMIT最大支持的软件定时器数；
-    -   配置OS\_SWTMR\_HANDLE\_QUEUE\_SIZE软件定时器队列最大长度；
-
-2.  创建定时器LOS\_SwtmrCreate。
-    -   创建一个指定计时时长、指定超时处理函数、指定触发模式的软件定时器；
-    -   返回函数运行结果，成功或失败；
-
-3.  启动定时器LOS\_SwtmrStart。
-4.  获得软件定时器剩余Tick数LOS\_SwtmrTimeGet。
-5.  停止定时器LOS\_SwtmrStop。
-6.  删除定时器LOS\_SwtmrDelete。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   软件定时器的回调函数中不要做过多操作，不要使用可能引起任务挂起或者阻塞的接口或操作。
->-   软件定时器使用了系统的一个队列和一个任务资源，软件定时器任务的优先级设定为0，且不允许修改  。
->-   系统可配置的软件定时器资源个数是指：整个系统可使用的软件定时器资源总个数，而并非是用户可使用的软件定时器资源个数。例如：系统软件定时器多占用一个软件定时器资源数，那么用户能使用的软件定时器资源就会减少一个。
->-   创建单次软件定时器，该定时器超时执行完回调函数后，系统会自动删除该软件定时器，并回收资源。
->-   创建单次不自删除属性的定时器，用户需要调用定时器删除接口删除定时器，回收定时器资源，避免资源泄露。

-## 开发流程<a name="section783435801510"></a>
-
-以创建任务为例，讲解开发流程。
-
-1.  锁任务调度LOS\_TaskLock，防止高优先级任务调度。
-2.  创建任务LOS\_TaskCreate。
-3.  解锁任务LOS\_TaskUnlock，让任务按照优先级进行调度。
-4.  延时任务LOS\_TaskDelay，任务延时等待。
-5.  挂起指定的任务LOS\_TaskSuspend，任务挂起等待恢复操作。
-6.  恢复挂起的任务LOS\_TaskResume。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   执行Idle任务时，会对待回收链表中的任务控制块和任务栈进行回收。
->-   任务名是指针，并没有分配空间，在设置任务名时，禁止将局部变量的地址赋值给任务名指针。
->-   任务栈的大小按8字节大小对齐。确定任务栈大小的原则是，够用就行，多了浪费，少了任务栈溢出。
->-   挂起当前任务时，如果已经锁任务调度，则无法挂起。
->-   Idle任务及软件定时器任务不能被挂起或者删除。
->-   在中断处理函数中或者在锁任务的情况下，执行LOS\_TaskDelay会失败。
->-   锁任务调度，并不关中断，因此任务仍可被中断打断。
->-   锁任务调度必须和解锁任务调度配合使用。
->-   设置任务优先级时可能会发生任务调度。
->-   可配置的系统最大任务数是指：整个系统的任务总个数，而非用户能使用的任务个数。例如：系统软件定时器多占用一个任务资源，那么用户能使用的任务资源就会减少一个。
->-   LOS\_CurTaskPriSet和LOS\_TaskPriSet接口不能在中断中使用，也不能用于修改软件定时器任务的优先级。
->-   LOS\_TaskPriGet接口传入的task ID对应的任务未创建或者超过最大任务数，统一返回-1。
->-   在删除任务时要保证任务申请的资源（如互斥锁、信号量等）已被释放。

-## 编程实例<a name="section460018317164"></a>
-
-本实例介绍基本的任务操作方法，包含2个不同优先级任务的创建、任务延时、任务锁与解锁调度、挂起和恢复等操作，阐述任务优先级调度的机制以及各接口的应用。示例代码如下：
-
-```

-
-    /* 创建高优先级任务，由于锁任务调度，任务创建成功后不会马上执行 */
-    ret = LOS_TaskCreate(&g_taskHiId, &initParam);

-编译运行得到的结果为：
-
-```
-LOS_TaskLock() Success!
-Example_TaskHi create Success!
-Example_TaskLo create Success!
-Enter TaskHi Handler.
-Enter TaskLo Handler.
-TaskHi LOS_TaskDelay Done.
-TaskHi LOS_TaskSuspend Success.

-## 开发流程<a name="section783435801510"></a>
-
-互斥锁典型场景的开发流程：
-
-1.  创建互斥锁LOS\_MuxCreate。
-2.  申请互斥锁LOS\_MuxPend。
-
-    申请模式有三种：无阻塞模式、永久阻塞模式、定时阻塞模式。
-
-    -   无阻塞模式：任务需要申请互斥锁，若该互斥锁当前没有任务持有，或者持有该互斥锁的任务和申请该互斥锁的任务为同一个任务，则申请成功。
-    -   永久阻塞模式：任务需要申请互斥锁，若该互斥锁当前没有被占用，则申请成功。否则，该任务进入阻塞态，系统切换到就绪任务中优先级高者继续执行。任务进入阻塞态后，直到有其他任务释放该互斥锁，阻塞任务才会重新得以执行。
-    -   定时阻塞模式：任务需要申请互斥锁，若该互斥锁当前没有被占用，则申请成功。否则该任务进入阻塞态，系统切换到就绪任务中优先级高者继续执行。任务进入阻塞态后，指定时间超时前有其他任务释放该互斥锁，或者用户指定时间超时后，阻塞任务才会重新得以执行。
-
-3.  释放互斥锁LOS\_MuxPost。
-    -   如果有任务阻塞于指定互斥锁，则唤醒被阻塞任务中优先级高的，该任务进入就绪态，并进行任务调度；
-    -   如果没有任务阻塞于指定互斥锁，则互斥锁释放成功。
-
-4.  删除互斥锁LOS\_MuxDelete。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   两个任务不能对同一把互斥锁加锁。如果某任务对已被持有的互斥锁加锁，则该任务会被挂起，直到持有该锁的任务对互斥锁解锁，才能执行对这把互斥锁的加锁操作。
->-   互斥锁不能在中断服务程序中使用。
->-   LiteOS-M内核作为实时操作系统需要保证任务调度的实时性，尽量避免任务的长时间阻塞，因此在获得互斥锁之后，应该尽快释放互斥锁。
->-   持有互斥锁的过程中，不得再调用LOS\_TaskPriSet等接口更改持有互斥锁任务的优先级。

-## 编程实例<a name="section1426719434114"></a>
-
-### 实例描述<a name="section896412438910"></a>
-
-本实例实现如下流程。
-
-1.  任务Example\_TaskEntry创建一个互斥锁，锁任务调度，创建两个任务Example\_MutexTask1、Example\_MutexTask2。Example\_MutexTask2优先级高于Example\_MutexTask1，解锁任务调度。
-2.  Example\_MutexTask2被调度，以永久阻塞模式申请互斥锁，并成功获取到该互斥锁，然后任务休眠100Tick，Example\_MutexTask2挂起，Example\_MutexTask1被唤醒。
-3.  Example\_MutexTask1以定时阻塞模式申请互斥锁，等待时间为10Tick，因互斥锁仍被Example\_MutexTask2持有，Example\_MutexTask1挂起。10Tick超时时间到达后，Example\_MutexTask1被唤醒，以永久阻塞模式申请互斥锁，因互斥锁仍被Example\_MutexTask2持有，Example\_MutexTask1挂起。
-4.  100Tick休眠时间到达后，Example\_MutexTask2被唤醒， 释放互斥锁，唤醒Example\_MutexTask1。Example\_MutexTask1成功获取到互斥锁后，释放，删除互斥锁。

-1.  调用中断创建接口HalHwiCreate创建中断。
-2.  调用TestHwiTrigger接口触发指定中断（该接口在测试套中定义，通过写中断控制器的相关寄存器模拟外部中断，一般的外设设备，不需要执行这一步）。
-3.  调用HalHwiDelete接口删除指定中断，此接口根据实际情况使用，判断是否需要删除中断。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->-   根据具体硬件，配置支持的最大中断数及可设置的中断优先级个数。
->-   中断处理程序耗时不能过长，否则会影响CPU对中断的及时响应。
->-   中断响应过程中不能直接、间接执行引起调度的LOS\_Schedule等函数。
->-   中断恢复LOS\_IntRestore\(\)的入参必须是与之对应的LOS\_IntLock\(\)的返回值（即关中断之前的CPSR值）。Cortex-M系列处理器中0-15中断为内部使用，因此不建议用户去申请和创建。

-    } else {
-        printf("Hwi create failed!\n");
-        return LOS_NOK;
-    }
-
-    /* 延时50个Ticks， 当有硬件中断发生时，会调用函数HwiUsrIrq*/
-    LOS_TaskDelay(50);
-

-    ret = HalHwiDelete(HWI_NUM_TEST);    
-    if(ret == LOS_OK){

-
-OpenHarmony LiteOS-M提供异常接管调测手段，帮助开发者定位分析问题。异常接管是操作系统对运行期间发生的异常情况进行处理的一系列动作，例如打印异常发生时异常类型、发生异常时的系统状态、当前函数的调用栈信息、CPU现场信息、任务调用堆栈等信息。
-
-## 运行机制<a name="section16618124317346"></a>
-
-栈帧用于保存函数调用过程中的函数参数、变量、返回值等信息。调用函数时，会创建子函数的栈帧，同时将函数入参、局部变量、寄存器入栈。栈帧从高地址向低地址生长。以ARM32 CPU架构为例，每个栈帧中都会保存PC、LR、SP和FP寄存器的历史值。LR链接寄存器（Link Register）指向函数的返回地址，FP帧指针寄存器（Frame Point）指向当前函数的父函数的栈帧起始地址。利用FP寄存器可以得到父函数的栈帧，从栈帧中获取父函数的FP，就可以得到祖父函数的栈帧，以此类推，可以追溯程序调用栈，得到函数间的调用关系。
-
-当系统发生异常时，系统打印异常函数的栈帧中保存的寄存器内容，以及父函数、祖父函数的栈帧中的LR链接寄存器、FP帧指针寄存器内容，用户就可以据此追溯函数间的调用关系，定位异常原因。
-
-堆栈分析原理如下图所示，实际堆栈信息根据不同CPU架构有所差异，此处仅做示意。
-
-**图 1**  堆栈分析原理示意图<a name="fig5280123462820"></a>  
-![](figures/堆栈分析原理示意图.png "堆栈分析原理示意图")
-
-图中不同颜色的寄存器表示不同的函数。可以看到函数调用过程中，寄存器的保存。通过FP寄存器，栈回溯到异常函数的父函数，继续按照规律对栈进行解析，推出函数调用关系，方便用户定位问题。

-### 定位流程<a name="section197332323815"></a>
-
-异常接管一般的定位步骤如下：
-
-1.  打开编译后生成的镜像反汇编（asm）文件。如果默认没有生成，可以使用<u>objdump</u>工具生成，命令为：
-
-    ```
-     arm-none-eabi-objdump -S -l XXX.elf
-    ```
-
-
-1.  搜索PC指针（指向当前正在执行的指令）在asm中的位置，找到发生异常的函数。
-
-    PC地址指向发生异常时程序正在执行的指令。在当前执行的二进制文件对应的asm文件中，查找PC值0x80037da，找到当前CPU正在执行的指令行，反汇编如下所示：
-
-    ```
-    UINT32 Get_Result_Exception_0(UINT16 dividend){
-     80037c8:	b480      	push	{r7}
-     80037ca:	b085      	sub	sp, #20
-     80037cc:	af00      	add	r7, sp, #0
-     80037ce:	4603      	mov	r3, r0
-     80037d0:	80fb      	strh	r3, [r7, #6]
-    kernel_liteos_m\targets\cortex-m7_nucleo_f767zi_gcc/Core/Src/exc_example.c:10
-        UINT32 divisor = 0;
-     80037d2:	2300      	movs	r3, #0
-     80037d4:	60fb      	str	r3, [r7, #12]
-    kernel_liteos_m\targets\cortex-m7_nucleo_f767zi_gcc/Core/Src/exc_example.c:11
-        UINT32 result = dividend / divisor;
-     80037d6:	88fa      	ldrh	r2, [r7, #6]
-     80037d8:	68fb      	ldr	r3, [r7, #12]
-     80037da:	fbb2 f3f3 	udiv	r3, r2, r3
-     80037de:	60bb      	str	r3, [r7, #8]
-    ```
-
-
-1.  可以看到:
-    1.  异常时CPU正在执行的指令是udiv	r3, r2, r3，其中r3取值为0，导致发生除零异常。
-    2.  异常发生在函数Get\_Result\_Exception\_0中。
-
-2.  根据LR值查找异常函数的父函数。
-
-    包含LR值0x80037fe的反汇编如下所示：
-
-    ```
-    080037ec <Get_Result_Exception_1>:
-    Get_Result_Exception_1():
-    kernel_liteos_m\targets\cortex-m7_nucleo_f767zi_gcc/Core/Src/exc_example.c:15
-    UINT32 Get_Result_Exception_1(UINT16 dividend){
-     80037ec:	b580      	push	{r7, lr}
-     80037ee:	b082      	sub	sp, #8
-     80037f0:	af00      	add	r7, sp, #0
-     80037f2:	4603      	mov	r3, r0
-     80037f4:	80fb      	strh	r3, [r7, #6]
-    kernel_liteos_m\targets\cortex-m7_nucleo_f767zi_gcc/Core/Src/exc_example.c:16
-        return Get_Result_Exception_0(dividend);
-     80037f6:	88fb      	ldrh	r3, [r7, #6]
-     80037f8:	4618      	mov	r0, r3
-     80037fa:	f7ff ffe5 	bl	80037c8 <Get_Result_Exception_0>
-     80037fe:	4603      	mov	r3, r0
-    ```
-
-
-1.  LR值80037fe上一行是bl	80037c8 <Get\_Result\_Exception\_0\>，此处调用了异常函数，调用异常函数的父函数为Get\_Result\_Exception\_1\(\)。
-2.  重复步骤3，解析异常信息中backtrace start至backtrace end之间的LR值，得到调用产生异常的函数调用栈关系，找到异常原因。

-OpenHarmony LiteOS-M内核的编译构建系统是一个基于gn和ninja的组件化构建系统，支持按组件配置、裁剪和拼装，按需构建出定制化的产品。编译构建系统的详细信息可以参考[编译构建概述](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/subsystems/%E7%BC%96%E8%AF%91%E6%9E%84%E5%BB%BA%E6%A6%82%E8%BF%B0.md)。本文主要介绍如何基于gn和ninja编译LiteOS-M工程。
-
-## 搭建开发环境<a name="section157851447151716"></a>
-
-在搭建各个开发板环境前，需要完成OpenHarmony系统基础环境搭建。系统基础环境主要是指OpenHarmony的编译环境和开发环境，详细介绍请参考官方站点[搭建系统基础环境](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/quick-start/%E6%90%AD%E5%BB%BA%E7%B3%BB%E7%BB%9F%E7%8E%AF%E5%A2%83.md)。开发者需要根据环境搭建文档，完成下述软件的安装：Python3.7+、gn、ninja、hb。对于LiteOS-M内核，还需要安装ARM GCC编译工具链。
-
-## 获取OpenHarmony源码<a name="section381985201816"></a>
-
-开发者需要在Linux服务器上通过Git克隆获取OpenHarmony最新源码，详细的源码获取方式，请见[源码获取](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/get-code/%E6%BA%90%E7%A0%81%E8%8E%B7%E5%8F%96.md)。获取OpenHarmony完整仓代码后，假设克隆目录为\~/openHarmony。
-
-## 获取示例工程源码<a name="section204717216181"></a>
-
-以开发板Nucleo-F767Zi为例，演示如何编译运行OpenHarmony LiteOS-M内核工程。在本地目录，执行下述命令克隆示例代码。
-
-```
-git clone https://gitee.com/harylee/nucleo_f767zi.git
-```
-
-假设克隆到的代码目录为\~/nucleo\_f767zi。 执行如下命令把代码目录的device、vendor目录复制到openHarmony工程的相应目录。
-
-```
-cp -r ~/nucleo_f767zi/device/st  ~/openHarmony/device/st
-cp -r ~/nucleo_f767zi/vendor/st  ~/openHarmony/vendor/st
-```
-
-关于示例代码目录的说明，可以参考资料站点[板级目录规范](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/porting/%E7%A7%BB%E6%A4%8D%E6%A6%82%E8%BF%B0-0.md#section6204129143013)。如果需要自行移植开发板，请参考[板级系统移植](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/porting/%E6%9D%BF%E7%BA%A7%E7%B3%BB%E7%BB%9F%E7%A7%BB%E6%A4%8D.md)。
-
-## 编译运行<a name="section9772514181917"></a>
-
-编译运行前，把交叉编译工具链bin目录配置到PATH环境变量中或者在device/st/nucleo\_f767zi/liteos\_m/config.gni文件中把board\_toolchain\_path配置项设置为交叉编译工具链bin目录。 在OpenHarmony根目录，执行hb set设置产品路径，选择nucleo\_f767zi产品，然后执行hb build开启编译。如下：
-
-```
-user@dev:~/OpenHarmony$ hb set
-[OHOS INFO] Input code path:          # 直接按回车，然后选择nucleo_f767zi产品即可
-OHOS Which product do you need?  nucleo_f767zi@st
-user@dev:~/OpenHarmony$ hb build
-```
-
-最终的镜像生成在\~/openHarmony/out/nucleo\_f767zi/目录中，通过STM32 ST-LINK Utility软件将镜像文件下载至单板查看运行效果。

-
-**图 1**  POSIX接口框架<a name="fig279734632911"></a>  
-![](figures/POSIX接口框架.png "POSIX接口框架")
-
-**musl libc**库支持POSIX标准，涉及的系统调用相关接口由OpenHarmony内核适配支持 ，以满足接口对外描述的功能要求。
-
-标准库支持接口的详细情况请参考C库的API文档，其中也涵盖了与POSIX标准之间的差异说明。
-
-## 操作实例<a name="section4807125622614"></a>
-
-在本示例中，主线程创建了THREAD\_NUM个子线程，每个子线程启动后等待被主线程唤醒，主线程成功唤醒所有子线程后，子线程继续执行直至生命周期结束，同时主线程通过pthread\_join方法等待所有线程执行结束。

-## 基本概念<a name="section1179311337405"></a>
-
-从系统的角度看，线程是竞争系统资源的最小运行单元。线程可以使用或等待CPU、使用内存空间等系统资源，并独立于其它线程运行。
-
-OpenHarmony内核每个进程内的线程独立运行、独立调度，当前进程内线程的调度不受其它进程内线程的影响。
-
-OpenHarmony内核中的线程采用抢占式调度机制，同时支持时间片轮转调度和FIFO调度方式。
-
-OpenHarmony内核的线程一共有32个优先级\(0-31\)，最高优先级为0，最低优先级为31。
-
-当前进程内高优先级的线程可抢占当前进程内低优先级线程，当前进程内低优先级线程必须在当前进程内高优先级线程阻塞或结束后才能得到调度。
-
-**线程状态说明：**
-
--   初始化（Init）：该线程正在被创建。
-
--   就绪（Ready）：该线程在就绪列表中，等待CPU调度。
-
--   运行（Running）：该线程正在运行。
-
--   阻塞（Blocked）：该线程被阻塞挂起。Blocked状态包括：pending\(因为锁、事件、信号量等阻塞\)、suspended（主动pend）、delay\(延时阻塞\)、pendtime\(因为锁、事件、信号量时间等超时等待\)。
-
--   退出（Exit）：该线程运行结束，等待父线程回收其控制块资源。

-
-**线程状态迁移说明：**
-
--   Init→Ready：
-
-    线程创建拿到控制块后为Init状态，处于线程初始化阶段，当线程初始化完成将线程插入调度队列，此时线程进入就绪状态。
-
--   Ready→Running：
-
-    线程创建后进入就绪态，发生线程切换时，就绪列表中最高优先级的线程被执行，从而进入运行态，但此刻该线程会从就绪列表中删除。
-
--   Running→Blocked：
-
-    正在运行的线程发生阻塞（挂起、延时、读信号量等）时，线程状态由运行态变成阻塞态，然后发生线程切换，运行就绪列表中剩余最高优先级线程。
-
--   Blocked→Ready ：
-
-    阻塞的线程被恢复后（线程恢复、延时时间超时、读信号量超时或读到信号量等），此时被恢复的线程会被加入就绪列表，从而由阻塞态变成就绪态。
-
--   Ready→Blocked：
-
-    线程也有可能在就绪态时被阻塞（挂起），此时线程状态会由就绪态转变为阻塞态，该线程从就绪列表中删除，不会参与线程调度，直到该线程被恢复。
-
--   Running→Ready：
-
-    有更高优先级线程创建或者恢复后，会发生线程调度，此刻就绪列表中最高优先级线程变为运行态，那么原先运行的线程由运行态变为就绪态，并加入就绪列表中。
-
--   Running→Exit：
-
-    运行中的线程运行结束，线程状态由运行态变为退出态。若未设置分离属性（PTHREAD\_CREATE\_DETACHED）的线程，运行结束后对外呈现的是Exit状态，即退出态。
-
-
-## 使用场景<a name="section44877547404"></a>
-
-线程创建后，用户态可以执行线程调度、挂起、恢复、延时等操作，同时也可以设置线程优先级和调度策略，获取线程优先级和调度策略。

-## 基本概念<a name="section9840143083510"></a>
-
-网络模块实现了TCP/IP协议栈基本功能，提供标准的POSIX socket接口。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->当前系统使用**lwIP**提供网络能力。
-
-## 使用场景<a name="section1575885183516"></a>
-
-针对用户态开发，OpenHarmony内核提供了一套网络功能系统调用接口，支持socket的创建关闭、数据收发、网络属性的设置等，通过C库提供标准的POSIX socket函数供开发者使用。

-OpenHarmony LiteOS-M内核是面向IoT领域构建的轻量级物联网操作系统内核，具有小体积、低功耗、高性能的特点。其代码结构简单，主要包括内核最小功能集、内核抽象层、可选组件以及工程目录等。OpenHarmony LiteOS-M内核架构包含硬件相关层以及硬件无关层，如下图所示，其中Kernel Arch模块属于硬件相关层，该模块按不同编译工具链、芯片架构分类，提供统一的HAL（Hardware Abstraction Layer）接口，提升了硬件易适配性，满足AIoT类型丰富的硬件和编译工具链的拓展；Components等其他模块属于硬件无关层，其中Kernel Task等内核模块提供基础能力，Components模块提供网络、文件系统等组件能力，Utils模块提供错误处理、调测等能力，KAL（Kernel Abstraction Layer）模块提供统一的标准接口。

-
-CPU体系架构分为通用架构定义和特定架构定义两层，通用架构定义层为所有体系架构都需要支持和实现的接口，特定架构定义层为特定体系架构所特有的部分。在新增一个体系架构的时候，必须需要实现通用架构定义层，如果该体系架构还有特有的功能，可以在特定架构定义层来实现。

-## 基础概念<a name="section17368154517335"></a>
-
-踩内存检测机制作为内核的可选功能，用于检测动态内存池的完整性。通过该机制，可以及时发现内存池是否发生了踩内存问题，并给出错误信息，便于及时发现系统问题，提高问题解决效率，降低问题定位成本。
-
-## 功能配置<a name="section4696190123420"></a>
-
-LOSCFG\_BASE\_MEM\_NODE\_INTEGRITY\_CHECK：开关宏，默认关闭；若打开这个功能，在target\_config.h中将这个宏定义为1。
-
-1.  开启这个功能，每次申请内存，会实时检测内存池的完整性。
-2.  如果不开启该功能，也可以调用LOS\_MemIntegrityCheck接口检测，但是每次申请内存时，不会实时检测内存完整性，而且由于节点头没有魔鬼数字（开启时才有，省内存），检测的准确性也会相应降低，但对于系统的性能没有影响，故根据实际情况开关该功能。
-
-由于该功能只会检测出哪个内存节点被破坏了，并给出前节点信息（因为内存分布是连续的，当前节点最有可能被前节点破坏）。如果要进一步确认前节点在哪里申请的，需开启内存泄漏检测功能，通过LR记录，辅助定位。
-
->![](public_sys-resources/icon-caution.gif) **注意：** 
->开启该功能，节点头多了魔鬼数字字段，会增大节点头大小。由于实时检测完整性，故性能影响较大；若性能敏感的场景，可以不开启该功能，使用LOS\_MemIntegrityCheck接口检测。
-
-## 开发指导<a name="section672362973417"></a>
-
-### 开发流程<a name="section026014863416"></a>
-
-通过调用LOS\_MemIntegrityCheck接口检测内存池是否发生了踩内存，如果没有踩内存问题，那么接口返回0且没有log输出；如果存在踩内存问题，那么会输出相关log，详见下文编程实例的结果输出。
-
-### 编程实例<a name="section186311302356"></a>
-
-本实例实现如下功能：
-
-1.  申请两个物理上连续的内存块；
-2.  通过memset构造越界访问，踩到下个节点的头4个字节；
-3.  调用LOS\_MemIntegrityCheck检测是否发生踩内存。
-
-### 示例代码<a name="section12709533354"></a>
-
-代码实现如下：
-
-```
-#include <stdio.h>
-#include <string.h>
-#include "los_memory.h"
-#include "los_config.h"
-
-void MemIntegrityTest(void)
-{
-    /* 申请两个物理连续的内存块 */
-    void *ptr1 = LOS_MemAlloc(LOSCFG_SYS_HEAP_ADDR, 8);
-    void *ptr2 = LOS_MemAlloc(LOSCFG_SYS_HEAP_ADDR, 8);
-    /* 第一个节点内存块大小是8字节，那么12字节的清零，会踩到第二个内存节点的节点头，构造踩内存场景 */
-    memset(ptr1, 0, 8 + 4);
-    LOS_MemIntegrityCheck(LOSCFG_SYS_HEAP_ADDR);
-}
-```
-
-### 结果验证<a name="section81214126369"></a>
-
-编译运行输出log如下：
-
-```
-[ERR][OsMemMagicCheckPrint], 2028, memory check error!

-## 基本概念<a name="section29197338383"></a>
-
-从系统的角度看，进程是资源管理单元。进程可以使用或等待CPU、使用内存空间等系统资源，并独立于其它进程运行。
-
-OpenHarmony内核的进程模块可以给用户提供多个进程，实现了进程之间的切换和通信，帮助用户管理业务程序流程。这样用户可以将更多的精力投入到业务功能的实现中。
-
-OpenHarmony内核中的进程采用抢占式调度机制，支持时间片轮转调度方式。
-
-OpenHarmony内核的进程一共有32个优先级\(0-31\)，用户进程可配置的优先级有22个\(10-31\)，最高优先级为10，最低优先级为31。
-
-高优先级的进程可抢占低优先级进程，低优先级进程必须在高优先级进程阻塞或结束后才能得到调度。
-
-每一个用户态进程均拥有自己独立的进程空间，相互之间不可见，实现进程间隔离。
-
-用户态根进程init由内核态创建，其它用户态进程均由init进程fork而来。
-
-**进程状态说明：**
-
--   初始化（Init）：该进程正在被创建。
-
--   就绪（Ready）：该进程在就绪列表中，等待CPU调度。
-
--   运行（Running）：该进程正在运行。
-
--   阻塞（Pending）：该进程被阻塞挂起。本进程内所有的线程均被阻塞时，进程被阻塞挂起。
-
--   僵尸态（Zombies）：该进程运行结束，等待父进程回收其控制块资源。
-
-
-**图 1**  进程状态迁移示意图<a name="fig1877059202911"></a>  
-![](figures/进程状态迁移示意图.png "进程状态迁移示意图")
-
-**进程状态迁移说明：**
-
--   Init→Ready：
-
-    进程创建或fork时，拿到该进程控制块后进入Init状态，处于进程初始化阶段，当进程初始化完成将进程插入调度队列，此时进程进入就绪状态。
-
--   Ready→Running：
-
-    进程创建后进入就绪态，发生进程切换时，就绪列表中最高优先级的进程被执行，从而进入运行态。若此时该进程中已无其它线程处于就绪态，则该进程从就绪列表删除，只处于运行态；若此时该进程中还有其它线程处于就绪态，则该进程依旧在就绪队列，此时进程的就绪态和运行态共存。
-
--   Running→Pending：
-
-    进程内所有的线程均处于阻塞态时，进程在最后一个线程转为阻塞态时，同步进入阻塞态，然后发生进程切换。
-
--   Pending→Ready：
-
-    阻塞进程内的任意线程恢复就绪态时，进程被加入到就绪队列，同步转为就绪态。
-
--   Ready→Pending：
-
-    进程内的最后一个就绪态线程处于阻塞态时，进程从就绪列表中删除，进程由就绪态转为阻塞态。
-
--   Running→Ready：
-
-    进程由运行态转为就绪态的情况有以下两种：
-
-    1.  有更高优先级的进程创建或者恢复后，会发生进程调度，此刻就绪列表中最高优先级进程变为运行态，那么原先运行的进程由运行态变为就绪态。
-    2.  若进程的调度策略为SCHED\_RR，且存在同一优先级的另一个进程处于就绪态，则该进程的时间片消耗光之后，该进程由运行态转为就绪态，另一个同优先级的进程由就绪态转为运行态。
-
--   Running→Zombies：
-
-    当进程的主线程或所有线程运行结束后，进程由运行态转为僵尸态，等待父进程回收资源。
-
-
-## 使用场景<a name="section85513272398"></a>
-
-进程创建后，用户只能操作自己进程空间的资源，无法操作其它进程的资源（共享资源除外）。 用户态允许进程挂起，恢复，延时等操作，同时也可以设置用户态进程调度优先级和调度策略，获取进程调度优先级和调度策略。进程结束的时候，进程会主动释放持有的进程资源，但持有的进程pid资源需要父进程通过wait/waitpid或父进程退出时回收。

-## 运行机制<a name="section165473517522"></a>
-
-静态内存实质上是一个静态数组，静态内存池内的块大小在初始化时设定，初始化后块大小不可变更。
-
-静态内存池由一个控制块LOS\_MEMBOX\_INFO和若干相同大小的内存块LOS\_MEMBOX\_NODE构成。控制块位于内存池头部，用于内存块管理，包含内存块大小uwBlkSize，内存块数量uwBlkNum，已分配使用的内存块数量uwBlkCnt和空闲内存块链表stFreeList。内存块的申请和释放以块大小为粒度，每个内存块包含指向下一个内存块的指针pstNext。

->初始化后的内存池的内存块数量，不等于总大小除于内存块大小，因为内存池的控制块和每个内存块的控制头，都存在内存开销，设置总大小时，需要将这些因素考虑进去。
-
-### 开发流程<a name="section1388511316548"></a>
-
-本节介绍使用静态内存的典型场景开发流程。
-
-1.  规划一片内存区域作为静态内存池。
-2.  调用LOS\_MemboxInit初始化静态内存池。
-
-    初始化会将入参指定的内存区域分割为N块（N值取决于静态内存总大小和块大小），将所有内存块挂到空闲链表，在内存起始处放置控制头。
-
-3.  调用LOS\_MemboxAlloc接口分配静态内存。
-
-    系统将会从空闲链表中获取第一个空闲块，并返回该内存块的起始地址。
-
-4.  调用LOS\_MemboxClr接口。
-
-    将入参地址对应的内存块清零。
-
-5.  调用LOS\_MemboxFree接口。
-
-    将该内存块加入空闲链表。
-
-
-### 编程实例<a name="section17801515105519"></a>
-
-本实例执行以下步骤：
-
-1.  初始化一个静态内存池。
-2.  从静态内存池中申请一块静态内存。
-3.  在内存块存放一个数据。
-4.  打印出内存块中的数据。
-5.  清除内存块中的数据。
-6.  释放该内存块。
-
-    示例代码如下：
-
-
-```
-#include "los_membox.h"
-
-VOID Example_StaticMem(VOID)
-{
-    UINT32 *mem = NULL;
-    UINT32 blkSize = 10;
-    UINT32 boxSize = 100;
-    UINT32 boxMem[1000];
-    UINT32 ret;
-
-    /*内存池初始化*/
-    ret = LOS_MemboxInit(&boxMem[0], boxSize, blkSize);
-    if(ret != LOS_OK) {
-        printf("Membox init failed!\n");
-        return;
-    } else {
-        printf("Membox init success!\n");
-    }
-
-    /*申请内存块*/
-    mem = (UINT32 *)LOS_MemboxAlloc(boxMem);
-    if (NULL == mem) {
-        printf("Mem alloc failed!\n");
-        return;
-    }
-    printf("Mem alloc success!\n");
-
-    /*赋值*/
-    *mem = 828;
-    printf("*mem = %d\n", *mem);
-
-    /*清除内存内容*/
-    LOS_MemboxClr(boxMem, mem);
-    printf("Mem clear success \n *mem = %d\n", *mem);
-
-    /*释放内存*/
-    ret = LOS_MemboxFree(boxMem, mem);
-    if (LOS_OK == ret) {
-        printf("Mem free success!\n");
-    } else {
-        printf("Mem free failed!\n");
-    }
-
-    return;
-}
-```
-
-### 结果验证<a name="section11818154112319"></a>
-
-输出结果如下：
-
-```
-Membox init success!
-Mem alloc success!
-*mem = 828
-Mem clear success   
-*mem = 0
-Mem free success!
-```

-
--   [使用场景](#section2350114718546)
--   [使用方法](#section3305151511559)
-
-## 使用场景<a name="section2350114718546"></a>
-
-在系统运行出现无响应等情况时，可以通过魔法键功能确定系统是否被锁中断（魔法键也无响应）或者查看系统任务运行状态等信息。
-
-在中断有响应的情况下，可以通过魔法键查看task信息中  cpup（CPU占用率）看是哪个任务长时间占用CPU导致系统其他任务无响应（一般为比较高优先级任务一直抢占CPU，导致低优先级任务无响应）。
-
-## 使用方法<a name="section3305151511559"></a>
-
-1.  配置宏LOSCFG\_ENABLE\_MAGICKEY。
-
-魔法键依赖于宏LOSCFG\_ENABLE\_MAGICKEY，使用时通过menuconfig在配置项中开启“Enable  MAGIC KEY”：
-
-Debug ---\> Enable MAGIC KEY；若关闭该选项，则魔法键失效。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->1.  可以在menuconfig中，将光标移动到LOSCFG\_ENABLE\_MAGICKEY上，输入“？”，查看帮助信息。
-
-2. 输入“ctrl + r”键，打开魔法键检测功能。
-
-在连接UART或者USB转虚拟串口的情况下，输入“ctrl + r” 键，打开魔法键检测功能，输出 “Magic key on”；再输入一次后，则关闭魔法键检测功能，输出“Magic key off”。魔法键功能如下：
-
--   ctrl + z：帮助键，输出相关魔法键简单介绍；
-
--   ctrl + t：输出任务相关信息；
-
--   ctrl + p：系统主动进入panic，输出panic相关信息后，系统会挂住；
-
--   ctrl + e：系统进行简单完整性内存池检查，检查出错会输出相关错误信息，检查正常会输出“system memcheck  over, all passed!”。
-
-
->![](public_sys-resources/icon-notice.gif) **须知：** 
->魔法键检测功能打开情况下，如果需要通过UART或者USB转虚拟串口输入特殊字符需避免与魔法键值重复，否则魔法键会被误触发，而原有设计功能可能出现错误。

-## 移植思路<a name="section9737174410328"></a>
-
-移植思路：通过修改工具链，交叉编译该三方库，生成OpenHarmony平台的可执行文件，最后再通过GN调用CMake的方式添加到OpenHarmony工程中。
-
-## 交叉编译<a name="section38205577332"></a>
-
-### 编译参考<a name="section1088111263418"></a>
-
-代码仓库的[README.md](https://github.com/google/double-conversion/blob/master/README.md)中详细介绍了使用CMake编译double-conversion库的步骤，以及测试方法。本文参考该指导设置该库的编译配置，并完成测试。若开发人员在移植过程中对该库的编译选项配置有疑惑的地方，可参考该指导。对于其他使用CMake可独立编译的三方库，在移植时可以参考其自带的编译指导。
-
-### 设置执行交叉编译<a name="section8168182883515"></a>
-
-CMake方式可通过指定工具链进行交叉编译，修改并编译该库，生成OpenHarmony平台的可执行文件，步骤如下：
-
-1.  设置工具链
-
-    将下列clang工具链配置添加到该工程的顶层CMakeLists.txt（即[表1中的该文件](#table824211132418)）中即可。
-
-    ```
-    set(CMAKE_CROSSCOMPILING TRUE)
-    set(CMAKE_SYSTEM_NAME Generic)
-    set(CMAKE_CXX_COMPILER_ID Clang)
-    set(CMAKE_TOOLCHAIN_PREFIX llvm-)
-    #指定c编译工具（确保工具链所在路径已经添加到了PATH环境变量中）和编译标志，使用clang编译时标志中必须指定--target，否则无法交叉编译。
-    set(CMAKE_C_COMPILER clang)
-    set(CMAKE_C_FLAGS "--target=arm-liteos -D__clang__ -march=armv7-a -w")
-    #指定c++编译工具（确保工具链所在路径已经添加到了PATH环境变量中）和编译标志，必须指定--target，否则无法交叉编译。
-    set(CMAKE_CXX_COMPILER clang++) 
-    set(CMAKE_CXX_FLAGS "--target=arm-liteos -D__clang__ -march=armv7-a -w")
-    #指定链接工具和链接标志，必须指定--target和--sysroot，其中OHOS_ROOT_PATH可通过cmake命令后缀参数来指定。
-    set(MY_LINK_FLAGS "--target=arm-liteos --sysroot=${OHOS_SYSROOT_PATH}")
-    set(CMAKE_LINKER clang)
-    set(CMAKE_CXX_LINKER clang++)
-    set(CMAKE_C_LINKER clang)
-    set(CMAKE_C_LINK_EXECUTABLE "${CMAKE_C_LINKER}
-    ${MY_LINK_FLAGS} <FLAGS> <LINK_FLAGS> <OBJECTS> -o <TARGET> <LINK_LIBRARIES>")
-    set(CMAKE_CXX_LINK_EXECUTABLE "${CMAKE_CXX_LINKER}
-    ${MY_LINK_FLAGS} <FLAGS> <LINK_FLAGS> <OBJECTS> -o <TARGET> <LINK_LIBRARIES>")
-    #指定链接库的查找路径。
-    set(CMAKE_SYSROOT ${OHOS_SYSROOT_PATH})
-    ```
-
-2.  执行编译
-
-    linux命令行中进入double-conversion的源文件目录（即[表1所示目录](#table824211132418)），执行下列命令：
-
-    ```
-    mkdir build && cd build
-    cmake .. -DBUILD_TESTING=ON -DOHOS_SYSROOT_PATH="..."
-    make -j
-    ```
-
-    其中OHOS\_SYSROOT\_PATH需用绝对路径指定出sysroot目录的位置，以OpenHarmony为例即目录openHarmony/prebuilts/lite/sysroot的绝对路径。
-
-3.  <a name="li15717101715249"></a>查看结果
-
-    步骤2操作完成后，build目录下会生成静态库文件和测试用例：

-
-1.  搭建OpenHarmony环境
-
-    以hi3518ev300为例，编译出OpenHarmony镜像，烧写到开发板，参考[开发Hi3518第一个示例程序](https://device.harmonyos.com/cn/docs/start/introduce/oem_camera_start_example-0000001051610926)。
-
-    进入系统如下所示：

-    **图 1**  OpenHarmony启动成功界面<a name="fig13279524162418"></a>  
-    ![](figures/OpenHarmony启动成功界面.png "OpenHarmony启动成功界面")
-
-2.  挂载nfs目录，将[表2](#table1452412391911)中test目录下cctest可执行文件放入nfs目录
-3.  执行用例
-
-    该库采用非交叉编译时用例是通过make test执行，CMake会有相关的执行结果统计；交叉编译时无法使用该方法，因此可直接执行生成的测试文件完成测试。
-
-    -   挂载成功后执行下列命令可列出用例所有条目：
-
-    ```
-    cd nfs
-    ./cctest --list
-    ```

-## 将该库编译添加到OpenHarmony工程中<a name="section1651053153715"></a>
-
-1.  复制库到OpenHarmony工程中
-
-    拷贝已经能够成功交叉编译的库到OpenHarmony的third\_party目录，为了不修改要移植的三方库目录下的BUILD.gn文件，再添加一层目录放置新增的gn转CMake编译适配文件，新增的文件有BUILD.gn、build\_thirdparty.py、 config.gni，新增后的目录结构如下所示。

-                "--command=${command}"
-            ]
-        }
-    }
-    ```
-
-    -   **新增的config.gni用于配置该库，实现如下，其他采用CMake方式可独立编译的三方库移植到OpenHarmony时只需修改CMAKE\_FLAG的配置即可。**
-
-    ```
-    #CMAKE_FLAG: config compile feature
-    CMAKE_FLAG = "-DBUILD_TESTING=ON -DCMAKE_CXX_STANDARD=11"
-

-    ```
-
-    -   **新增的build\_thirdparty.py实现如下，其他采用CMake方式可独立编译的三方库移植到OpenHarmony时无需修改即可使用。**
-
-    ```

-    
-        if args.path:
-            curr_dir = os.getcwd()
-            os.chdir(args.path)
-            if args.command:
-                if '&&' in args.command:

-            os.chdir(curr_dir)
-    
-    if __name__ == '__main__':
-        sys.exit(main())
-    ```
-
-    -   在配置文件中添加开关控制该库编译，默认设为关闭
-
-    在//build/lite/ohos\_var.gni文件中添加下列配置：
-
-    ```
-    declare_args() {
-        ohos_build_thirdparty_migrated_from_fuchisa = true
-    }
-    ```
-
-3.  编译构建
-
-    -   手动单独构建：
-
-    执行下列命令
-
-    ```
-    hb build -T //third_party/double-conversion:double-conversion
-    ```
-
-    编译成功则[build](#li15717101715249)目录下会生成静态库文件和测试用例

-## 设置交叉编译<a name="section81263255384"></a>
-
-设置Makefile的交叉编译工具链，修改并编译该库，生成OpenHarmony平台的可执行文件，步骤如下：
-
-1.  设置工具链
-
-    将下列clang工具链配置替换掉yxml库根目录的MakeFile（即[表1中的文件](#table16520154171813)）中的原有配置。
-
-    clang工具链配置
-
-    ```
-    #设置交叉编译工具链，确保工具链所在路径已经添加到了PATH环境变量中
-    CC:=clang
-    AR:=llvm-ar
-    #cflags中必须要添加--target及--sysroot选项
-    CFLAGS:=-Wall -Wextra -Wno-unused-parameter -O2 -g --target=arm-liteos -march=armv7-a --sysroot=$(OHOS_ROOT_PATH)prebuilts/lite/sysroot
-    ```
-
-    原有配置
-
-    ```
-    CC:=gcc
-    AR:=ar
-    CFLAGS:=-Wall -Wextra -Wno-unused-parameter -O2 -g
-    ```
-
-2.  执行编译
-
-    linux命令行中进入yxml的源文件目录（即图1所示目录），执行下列命令：
-
-    ```
-    make test OHOS_SYSROOT_PATH=...
-    ```
-
-    其中OHOS\_SYSROOT\_PATH需用绝对路径指定出sysroot所在目录，以OpenHarmony为例即源码根目录prebuilts/lite/sysroot/所在的绝对路径。
-

-test.sh内容如下所示：
-
-```
-#!/bin/sh
-for i in *.xml; do
-  b=`basename $i .xml`
-  o=${b}.out
-  t=${b}.test
-  ./test <$i >$t

-    echo "Test failed for $i:"
-    diff -u $o $t
-    exit 1
-  fi
-done
-echo "All tests completed successfully."
-```
-
-由于OpenHarmony的shell中暂不支持输入输出重定向（<和\>），所以测试时需要将输入\*.xml文件内容直接复制进shell后回车，输出内容会直接展示在shell窗口。过程如下：
-
-下列操作假定已按照2.4节的步骤搭建OpenHarmony，挂载并进入nfs目录：
-
-1.  执行下列命令
-
-    ```
-    ./test
-    ```
-
-2.  复制\*.xml内容到shell
-
-    以[test目录](#table115941423164318)下pi01.xml为例，内容如下，输入到shell并回车：
-
-    ```
-    <?SomePI abc?><a/>
-    ```
-
-3.  比较shell中输出的内容与[test目录](#table115941423164318)中对应的\*.out文件是否一致
-
-    输出结果如下：
-
-    ```
-    pistart SomePI
-    picontent abc
-    piend
-    elemstart a
-    elemend
-    ok
-    ```
-
-    经比较与[test目录](#table115941423164318)下pi01.out内容一致，测试通过。

-## 将该库编译添加到OpenHarmony工程中<a name="section1898016213406"></a>
-
-yxml库添加的过程除了适配文件build.gn和config.gni有些许变化外，其他和double-conversion库完全一致，参考[CMake方式组织编译的库移植](CMake方式组织编译的库移植.md#section1651053153715)的配置过程。要修改的适配文件及添加后的目录结构如下：
-
--   yxml库新增的BUILD.gn实现如下：
-
-```
-import("config.gni")
-group("yxml") {
-    if (ohos_build_thirdparty_migrated_from_fuchisa == true) {
-        deps = [":make"]
-    }
-}
-if (ohos_build_thirdparty_migrated_from_fuchisa == true) {
-    action("make") {
-        script = "//third_party/yxml/build_thirdparty.py"
-        outputs = ["$target_out_dir/log_yxml.txt"]
-        exec_path = rebase_path(rebase_path("./yxml", root_build_dir))
-        command = "make clean && $MAKE_COMMAND"
-        args = [
-            "--path=$exec_path",
-            "--command=${command}"
-        ]
-    }
-}
-```
-
--   yxml库新增的config.gni配置如下：
-
-```
-TEST_ENABLE = "YES"
-
-if (TEST_ENABLE == "YES") {
-    MAKE_COMMAND = "make test OHOS_SYSROOT_PATH=${ohos_root_path}prebuilts/lite/sysroot/"
-} else {
-    MAKE_COMMAND = "make OHOS_SYSROOT_PATH=${ohos_root_path}prebuilts/lite/sysroot/"

-## XTS简介<a name="section6725155811454"></a>
-
-XTS是OpenHarmony生态认证测试套件的集合，当前包括acts（application compatibility test suite）应用兼容性测试套。test/xts仓当前包括acts与tools软件包：
-
--   acts，存放acts相关测试用例源码与配置文件，其目的是帮助终端设备厂商尽早发现软件与OpenHarmony的不兼容性，确保软件在整个开发过程中满足OpenHarmony的兼容性要求。
--   tools，存放acts相关测试用例开发框架。
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->XTS的启动依赖SAMGR系统服务。
-
-适配分为两步，包括：
-
-1.  将XTS认证子系统加入编译组件中。
-2.  执行联接类模组acts测试用例。
-
-### 将XTS认证子系统加入编译组件中<a name="section46981118105417"></a>
-
-举例：将XTS认证子系统加入hispark\_aries产品编译组件中为例。
-
-1.  在vendor/hisilicon/hispark\_aries/config.json中加入XTS认证子系统定义：
-
-    ```
-    {
-        "subsystem": "test",
-        "components": [
-           { "component": "xts_acts", "features":[] },
-           { "component": "xts_tools", "features":[] }
-         ]
-    },
-    ```
-
-2.  Debug版本才会触发XTS认证子系统编译；
-
-### 执行联接类模组acts测试用例<a name="section9489122319819"></a>
-
-举例：以hispark\_aries产品执行联接类模组acts测试用例为例。
-
-1.  获取编译镜像。
-
-    请在如下目录获取版本镜像：out/hispark\_pegasus/wifiiot\_hispark\_pegasus/。
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >判断当前版本镜像是否集成acts测试套件方法：在map文件中查看对应.a是否被编译即可。
-
-2.  版本镜像烧录进开发板。
-3.  测试步骤。
-
-    （1）使用串口工具登录开发板，并保存串口打印信息。
-
-    （2）重启设备，查看串口日志。
-
-4.  测试结果分析指导。
-
-    （1）基于串口打印日志进行分析；
-
-    （2）每个测试套件执行以“Start to run test suite”开始，以“xx Tests xx Failures xx Ignored”结束。

+# 三方组件适配<a name="ZH-CN_TOPIC_0000001117478960"></a>
+
+如果需要使用third\_party目录下与产品相关的三方组件，可能需要对三方组件进行适配，下面以比较常用的mbedtls为例，介绍下适配步骤，注意本小节中仅介绍如何将适配的代码与OpenHarmony的编译框架融合，不会详细介绍mbedtls本身的原理和适配代码的具体逻辑，这些内容请参考mbedtls官方网站上的适配指南。
+
+1.  编写适配层代码
+
+    根据mbedtls官网的适配指南，编写需要的适配层代码，以适配硬件随机数举例，下面的路径都是相对third\_party/mbedtls的路径：
+
+    1.  拷贝include/mbedtls/config.h到ports目录下，并修改打开MBEDTLS\_ENTROPY\_HARDWARE\_ALT开关。
+    2.  在ports目录下创建entropy\_poll\_alt.c文件include并实现entropy\_poll.h中的硬件随机数接口
+    3.  在BUILD.gn中的mbedtls\_sources中增加刚才适配的entropy\_poll\_alt.c的路径
+    4.  在BIULD.gn中的lite\_library\("mbedtls\_static"\)中增加一行MBEDTLS\_CONFIG\_FILE指定新配置文件的位置
+
+        ```
+        lite_library("mbedtks_static") {
+          ...  
+          defines += ["MBEDTLS_CONFIG_FILE=<../port/config.h>"]
+          ...
+        }
+        ```
+
+
+    注意，上面的修改最好都新建一个config或者新建一个xxx\_alt.c文件来修改，不要直接在原先的代码中修改，侵入式的修改会导致后续版本升级出现大量零散冲突，增加升级维护成本。
+
+2.  制作patch
+
+    由于上面的适配是硬件相关的，上库代码时，不能直接放到通用的third\_party/mbedtls目录中，因此需要将上面的修改制作成patch，在编译之前通过打patch的方式注入到代码中。
+
+    1.  首先增加设备的patch配置文件device/<company\>/<board\>/patch.yml
+    2.  编辑device/<company\>/<board\>/patch.yml，增加要打的patch的信息：
+
+        ```
+        # 需要打patch的路径，路径均为相对代码根目录的路径
+        third_party/mbedtls:
+          # 该路径下需要打的patch存放路径
+          - device/<company>/<board>/third_party/mbedtls/adapter.patch
+        third_party/wpa_supplicant:
+          # 当一个路径下有多个patch的时候会依次执行patch
+          - device/<company>/<board>/third_party/wpa_supplicant/xxxxx.patch
+          - device/<company>/<board>/third_party/wpa_supplicant/yyyyy.patch
+        ...
+        ```
+
+    3.  制作上述**步骤1**修改的patch并放到对应的目录即可
+
+3.  使用带patch的编译
+
+    想要在编译的时候带上patch，其他步骤不变，仅需要在触发编译的时候加上 --patch，例如全编译的命令编程
+
+    ```
+    hb build -f --patch
+    ```
+
+    >![](../public_sys-resources/icon-caution.gif) **注意：** 
+    >最后一次打patch的产品信息会被记录，在进行下一次编译操作时，会对上一次的patch进行回退（即执行\`patch -p1 -R < xxx\`），回退patch失败或新增patch失败均会终止编译过程，请解决patch冲突后再次尝试编译。

+## XTS简介<a name="section6725155811454"></a>
+
+XTS是OpenHarmony生态认证测试套件的集合，当前包括acts（application compatibility test suite）应用兼容性测试套。test/xts仓当前包括acts与tools软件包：
+
+-   acts，存放acts相关测试用例源码与配置文件，其目的是帮助终端设备厂商尽早发现软件与OpenHarmony的不兼容性，确保软件在整个开发过程中满足OpenHarmony的兼容性要求。
+-   tools，存放acts相关测试用例开发框架。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>XTS的启动依赖SAMGR系统服务。
+
+适配分为两步，包括：
+
+1.  将XTS认证子系统加入编译组件中。
+2.  执行联接类模组acts测试用例。
+
+### 将XTS认证子系统加入编译组件中<a name="section46981118105417"></a>
+
+举例：将XTS认证子系统加入hispark\_aries产品编译组件中为例。
+
+1.  在vendor/hisilicon/hispark\_aries/config.json中加入XTS认证子系统定义：
+
+    ```
+    {
+        "subsystem": "test",
+        "components": [
+           { "component": "xts_acts", "features":[] },
+           { "component": "xts_tools", "features":[] }
+         ]
+    },
+    ```
+
+2.  Debug版本才会触发XTS认证子系统编译；
+
+### 执行联接类模组acts测试用例<a name="section9489122319819"></a>
+
+举例：以hispark\_aries产品执行联接类模组acts测试用例为例。
+
+1.  获取编译镜像。
+
+    请在如下目录获取版本镜像：out/hispark\_pegasus/wifiiot\_hispark\_pegasus/。
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >判断当前版本镜像是否集成acts测试套件方法：在map文件中查看对应.a是否被编译即可。
+
+2.  版本镜像烧录进开发板。
+3.  测试步骤。
+
+    （1）使用串口工具登录开发板，并保存串口打印信息。
+
+    （2）重启设备，查看串口日志。
+
+4.  测试结果分析指导。
+
+    （1）基于串口打印日志进行分析；
+
+    （2）每个测试套件执行以“Start to run test suite”开始，以“xx Tests xx Failures xx Ignored”结束。

+# 内核基础适配<a name="ZH-CN_TOPIC_0000001063432950"></a>
+
+-   [基础适配](#section14523241594)
+-   [特性配置项](#section112994366592)
+
+芯片架构适配完成后，liteos-m提供系统运行所需的系统初始化流程和定制化配置选项。移植过程中，需要关注初始化流程中跟硬件配置相关的函数；了解内核配置选项，才能裁剪出适合单板的最小内核。
+
+## 基础适配<a name="section14523241594"></a>
+
+如下图所示，基础适配主要分为以下两步：
+
+1.  启动文件startup.S和相应链接配置文件。
+2.  main. c中的串口初始化和tick中断注册。
+
+**图 1**  启动流程<a name="fig10838105524917"></a>  
+
+
+![](figure/zh-cn_image_0000001073943511.png)
+
+启动文件startup.S需要确保中断向量表的入口函数（例如reset\_vector）放在RAM的首地址，它由链接配置文件来指定。其中iar、keil和gcc工程的链接配置文件分别为xxx.icf、xxx.sct和xxx.ld，如果startup.S已经完成系统时钟初始化，并且能够引导到main函数，则启动文件不需要进行修改，采用厂商自带的startup.S即可，否则需要实现以上功能。
+
+在main.c文件中，需要关注串口初始化UartInit和系统Tick的handler函数注册。
+
+-   UartInit函数表示单板串口的初始化，具体的函数名根据单板自行定义。这个函数是可选的，用户可以根据硬件单板是否支持串口来自行选择调用该函数。如果硬件单板支持串口，则该函数需要完成使能串口TX和RX通道，设置波特率。
+-   HalTickStart设置tick中断的handler函数OsTickHandler。
+
+对于中断向量表不可重定向的芯片，需要关闭LOSCFG\_PLATFORM\_HWI宏，并且在startup.S中新增tick中断的handler函数。
+
+## 特性配置项<a name="section112994366592"></a>
+
+liteos\_m的完整配置能力及默认配置在los\_config.h定义，该头文件中的配置项可以根据不同的单板进行裁剪配置。
+
+如果针对这些配置项需要进行不同的板级配置，则可将对应的配置项直接定义到对应单板的device/xxxx/target\_config.h文件中，其他未定义的配置项，采用los\_config.h中的默认值。
+
+一份典型的配置参数如下：

+## 移植场景<a name="section93781277367"></a>
+
+芯片架构适配是可选过程，如果在liteos\_m/kernel/arch目录下已经支持对应芯片架构，则可以跳过芯片架构适配，进行单板适配过程，否则需要进行芯片架构移植工作。
+
+## 目录规范<a name="section18127744153119"></a>
+
+模组芯片使用的内核为liteos-m，liteos-m中主要分为KAL、Components、Kernel和Utils四个模块。
+
+-   KAL模块作为内核对外的接口依赖Components模块和Kernel模块。
+-   Components模块可插拔，它依赖Kernel模块。
+
+-   在Kernel模块中，其中硬件相关的代码放在kernel的arch目录中，其余为硬件无关的代码。内核功能集（task、sem等）的实现依赖硬件相关的arch代码，例如任务上下文切换、原子操作等。
+-   Utils模块作为基础代码块，被其他模块依赖。
+

+
+
+![](figure/zh-cn_image_0000001072304191.png)
+
+内核的目录结构和说明如下：
+
+```

+
+## 芯片架构适配点<a name="section137431650339"></a>
+
+如内核的[目录结构](#section18127744153119)所示，arch/include定义通用的芯片架构所需要实现的函数，另外芯片架构相关的代码会有部分的汇编代码，而汇编代码会因编译工具链的不同而不同，因此在具体的芯片架构下，还包含不同工具链（iar、keil、gcc等）的实现。
+
+arch/include 目录定义通用的文件以及函数列表，该目录下的所有函数在新增arch组件时都需要适配，详见每一个头文件：
+
+```
+los_arch.h                        --- 定义芯片架构初始化所需要的函数
+los_atomic.h                      --- 定义芯片架构所需要实现的原子操作函数
+los_context.h                     --- 定义芯片架构所需要实现的任务上下文相关函数
+los_interrupt.h                   --- 定义芯片架构所需要实现的中断和异常相关的函数
+los_timer.h                       --- 定义芯片架构所需要实现的系统时钟相关的函数
+```

+
+在工程device目录下添加编译main.c示例程序文件，此示例程序的主要目的是：LOS\_KernelInit完成之后，创建两个任务，循环调度延时并打印日志信息，通过此方法可以验证系统是否可正常调度以及时钟是否正常。
+
+```
+VOID TaskSampleEntry2(VOID) // 任务2的入口函数
+{
+    while(1) {

+    stTask1.usTaskPrio   = 6; //stTask1的任务优先级设定，不同于stTask2
+    uwRet = LOS_TaskCreate(&taskID1, &stTask1);
+
+    stTask1.pfnTaskEntry = (TSK_ENTRY_FUNC)TaskSampleEntry2;
+    stTask1.uwStackSize  = 0X1000;
+    stTask1.pcName       = "taskSampleEntry2";
+    stTask1.usTaskPrio   = 7;

+    }
+    while (1) {
+        __asm volatile("wfi");
+    }
+}
+```
+
+第一个任务运行正常后，说明最小系统的核心流程基本OK；由于xts用例框架对外依赖较多，主要是utils、bootstrap的链接脚本和编译框架，暂时无法支撑内核单独跑xts；此处略过内核测试套的测试，可以通过[XTS测试套](transplant-chip-board-xts.md)来覆盖最小系统是否完整移植成功。

+本文为OpenHarmony平台系统开发人员和芯片（或模组）制造商提供基础的开发移植指导，典型的芯片架构例如cortex-m系列、risc-v系列等都可以按照本文进行移植，暂时不支持蓝牙服务。OpenHarmony是个持续演进的复杂项目，随着版本和API的改变，本文将会不断更新。
+
+本文要求读者具有一定的嵌入式系统开发经验，因此它的重点未放在基本的OS基础介绍，而更多地描述OpenHarmony平台移植过程中主要操作和所需要关注的方面。
+
+## 移植目录<a name="section284217487490"></a>
+
+OpenHarmony整体工程较为复杂，目录及实现为系统本身功能，如果不涉及复杂的特性增强，不需要关注每一层实现，移植过程中重点关注如下目录即可：

+HDF驱动被设计为可以跨OS使用的驱动程序，HDF驱动框架会为驱动达成这个目标提供有力的支撑。开发HDF驱动中，请尽可能只使用HDF驱动框架提供的接口，否则会导致驱动丧失跨OS使用的特性。在开始驱动开发前，建议先了解[HDF驱动框架](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/driver/HDF%E9%A9%B1%E5%8A%A8%E6%A1%86%E6%9E%B6.md)。

+本章节讲解如何移植各类器件驱动。
+
+## LCD驱动移植<a name="section1574513454119"></a>
+
+移植LCD驱动的主要工作是编写一个驱动，在驱动中生成模型的实例，并完成注册。
+
+这些LCD的驱动被放置在源码目录//drivers/framework/model/display/driver/panel中。
+
+1.  创建Panel驱动
+
+    创建HDF驱动，在驱动初始化中调用RegisterPanel接口注册模型实例。如:
+
+    ```
+    int32_t LCDxxEntryInit(struct HdfDeviceObject *object)
+    {
+        struct PanelData *panel = CreateYourPanel();
+        // 注册模型实例
+        if (RegisterPanel(panel) != HDF_SUCCESS) {
+            HDF_LOGE("%s: RegisterPanel failed", __func__);
+            return HDF_FAILURE;
+        }
+        return HDF_SUCCESS;
+    }
+    
+    struct HdfDriverEntry g_xxxxDevEntry = {
+        .moduleVersion = 1,
+        .moduleName = "LCD_XXXX",
+        .Init = LCDxxEntryInit,
+    };
+    
+    HDF_INIT(g_xxxxDevEntry);
+    ```
+
+2.  配置加载panel驱动
+
+    产品的所有设备信息被定义在源码文件//vendor/vendor\_name/product\_name/config/device\_info/device\_info.hcs中。修改该文件，在display的host中，名为device\_lcd的device中增加配置。
+
+    >![](../public_sys-resources/icon-caution.gif) **注意：** 
+    >moduleName 要与panel驱动中的moduleName相同。
+
+    ```
+    root {
+        ...
+        display :: host {
+            device_lcd :: device {
+                    deviceN :: deviceNode {
+                        policy = 0;
+                        priority = 100;
+                        preload = 2;
+                        moduleName = "LCD_XXXX";
+                    }
+            }
+        }
+    }
+    ```
+
+
+## TP驱动移植<a name="section20284142116422"></a>
+
+本节描述如何移植触摸屏驱动。触摸屏的器件驱动被放置在源码目录//drivers/framework/model/input/driver/touchscreen中。 移植触摸屏驱动主要工作是向系统注册ChipDevice模型实例。
+
+详细的驱动开发指导，请参考  [TOUCHSCREEN开发指导](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/driver/TOUCHSCREEN.md)。
+
+1.  创建触摸屏器件驱动
+
+    在上述touchscreen目录中创建名为touch\_ic\_name.c的文件。编写如下内容
+
+    ```
+    #include "hdf_touch.h"
+    
+    static int32_t HdfXXXXChipInit(struct HdfDeviceObject *device)
+    {
+        ChipDevice *tpImpl = CreateXXXXTpImpl();
+        if(RegisterChipDevice(tpImpl) != HDF_SUCCESS) { // 注册ChipDevice模型
+            ReleaseXXXXTpImpl(tpImpl);
+            return HDF_FAILURE;
+        }
+        return HDF_SUCCESS;
+    }
+    
+    struct HdfDriverEntry g_touchXXXXChipEntry = {
+        .moduleVersion = 1,
+        .moduleName = "HDF_TOUCH_XXXX", // 注意这里的moduleName要与后续的配置完全一致
+        .Init = HdfXXXXChipInit,
+    };
+    
+    HDF_INIT(g_touchXXXXChipEntry);
+    ```
+
+    其中ChipDevice中要实现如下方法：

+
+具体的移植步骤如下：
+
+1.  创建HDF WLAN 芯片驱动
+
+    在目录/device/vendor\_name/peripheral/wifi/chip\_name/ 创建文件 hdf\_wlan\_chip\_name.c。内容模板如下：
+
+    ```
+    static int32_t HdfWlanHisiChipDriverInit(struct HdfDeviceObject *device) {
+        static struct HdfChipDriverFactory factory = CreateChipDriverFactory(); // 需要移植者实现的方法
+        struct HdfChipDriverManager *driverMgr = HdfWlanGetChipDriverMgr();
+        if (driverMgr->RegChipDriver(&factory) != HDF_SUCCESS) { // 注册驱动工厂
+            HDF_LOGE("%s fail: driverMgr is NULL!", __func__);
+            return HDF_FAILURE;
+        }
+        return HDF_SUCCESS;
+    }
+    
+    struct HdfDriverEntry g_hdfXXXChipEntry = {
+        .moduleVersion = 1,
+        .Init = HdfWlanXXXChipDriverInit,
+        .Release = HdfWlanXXXChipRelease,
+        .moduleName = "HDF_WIFI_CHIP_XXX" // 注意：这个名字要与配置一致
+    };
+    
+    HDF_INIT(g_hdfXXXChipEntry);
+    ```
+
+    在上述代码的CreateChipDriverFactory方法中，需要创建一个HdfChipDriverFactory类型的对象。该对象提供如下方法

+
+2.  编写配置文件描述驱动支持的芯片
+
+    在产品配置目录下创建芯片的配置文件，保存至源码路径//vendor/vendor\_name/product\_name/config/wifi/wlan\_chip\_chip\_name.hcs
+
+    该文件模板如下：
+
+    ```
+    root {
+        wlan_config {
+            chip_name :& chipList {
+                chip_name :: chipInst {
+                    match_attr = "hdf_wlan_chips_chip_name"; /* 这是配置匹配属性，用于提供驱动的配置根 */
+                    driverName = "driverName"; /* 需要与HdfChipDriverFactory中的driverName相同*/
+                    sdio {
+                        vendorId = 0xXXXX; /* your vendor id */
+                        deviceId = [0xXXXX]; /*your supported devices */
+                    }
+                }
+            }
+        }
+    }
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >路径和文件中的vendor\_name、product\_name、chip\_name请替换成实际名称
+    >vendorId 和 deviceId需要根据实际芯片的识别码进行填写。
+
+3.  编写配置文件，加载驱动
+
+    产品的所有设备信息被定义在源码文件//vendor/vendor\_name/product\_name/config/device\_info/device\_info.hcs中。修改该文件，在名为network的host中，名为device\_wlan\_chips的device中增加配置。模板如下：
+
+    ```
+                    deviceN :: deviceNode {
+                        policy = 0;
+                        preload = 2;
+                        moduleName = "HDF_WLAN_CHIPS";
+                        deviceMatchAttr = "hdf_wlan_chips_chip_name";
+                        serviceName = "driverName";
+                    }
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >moduleName 要与HDF WLAN 芯片驱动中的moduleName相同。
+
+4.  修改Kconfig文件，让移植的WLAN模组出现再内核配置中
+
+    在device/vendor\_name/drivers/Kconfig中增加配置菜单，模板如下
+
+    ```
+    config DRIVERS_HDF_WIFI_chip_name
+        bool "Enable chip_name Host driver"
+        default n
+        depends on DRIVERS_HDF_WLAN   help
+          Answer Y to enable chip_name Host driver.
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >请替换模板中的chip\_name为实际的芯片名称
+
+5.  修改构建脚本，让驱动参与内核构建
+
+    在源码文件//device/vendor\_name/drivers/lite.mk末尾追加如下内容
+
+    ```
+    ifeq ($(LOSCFG_DRIVERS_HDF_WIFI_chip_name), y)
+        # 构建完成要链接一个叫hdf_wlan_chipdriver_chip_name的对象，建议按这个命名，防止冲突
+        LITEOS_BASELIB += -lhdf_wlan_chipdriver_chip_name
+        # 增加构建目录gpio
+        LIB_SUBDIRS    += ../peripheral/wifi/chip_name
+    endif
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >请替换模板中的chip\_name为实际的芯片名称

+HDF为所有的平台驱动都创建了驱动模型，移植平台驱动的主要工作是向模型注入实例。 这些模型你可以在源码目录//drivers/framework/support/platform/include中找到定义。
+
+本节我们会以GPIO为例，讲解如何移植平台驱动，移植过程包含以下步骤：
+
+1.  创建GPIO驱动
+
+    在源码目录//device/vendor\_name/soc\_name/drivers/gpio中创建文件soc\_name\_gpio.c 内容模板如下：
+
+    ```
+    #include "gpio_core.h"
+    
+    // 定义GPIO结构体，如果需要的话
+    struct SocNameGpioCntlr {
+        struct GpioCntlr cntlr;  // 这是HDF GPIO驱动框架需要的结构体
+        int myData; // 以下是当前驱动自身需要的
+    };
+    
+    // Bind 方法在HDF驱动中主要用户对外发布服务，这里我们不需要，直接返回成功即可
+    static int32_t GpioBind(struct HdfDeviceObject *device)
+    {
+        (void)device;
+        return HDF_SUCCESS;
+    }
+    
+    // Init方法时驱动初始化的入口，我们需要在Init方法中完成模型实例的注册
+    static int32_t GpioInit(struct HdfDeviceObject *device)
+    {
+        SocNameGpioCntlr *impl = CreateGpio(); // 你的创建代码
+        ret = GpioCntlrAdd(&impl->cntlr);  // 注册GPIO模型实例
+        if (ret != HDF_SUCCESS) {
+            HDF_LOGE("%s: err add controller:%d", __func__, ret);
+            return ret;
+        }
+        return HDF_SUCCESS;
+    }
+    
+    // Release方法会在驱动卸载时被调用，这里主要完成资源回收
+    static void GpioRelease(struct HdfDeviceObject *device)
+    {
+        // GpioCntlrFromDevice 方法能从抽象的设备对象中获得init方法注册进去的模型实例。
+        struct GpioCntlr *cntlr = GpioCntlrFromDevice(device);
+        //资源释放...
+    }
+    
+    struct HdfDriverEntry g_gpioDriverEntry = {
+        .moduleVersion = 1,
+        .Bind = GpioBind,
+        .Init = GpioInit,
+        .Release = GpioRelease,
+        .moduleName = "SOC_NAME_gpio_driver", // 这个名字我们稍后会在配置文件中用到，用来加载驱动。
+    };
+    HDF_INIT(g_gpioDriverEntry); // 注册一个GPIO的驱动入口
+    ```
+
+2.  创建厂商驱动构建入口
+
+    如前所述device/vendor\_name/drivers/lite.mk是厂商驱动的构建的入口。我们需要从这个入口开始，进行构建
+
+    ```
+    #文件device/vendor_name/drivers/lite.mk
+    
+    SOC_VENDOR_NAME := $(subst $/",,$(LOSCFG_DEVICE_COMPANY))
+    SOC_NAME := $(subst $/",,$(LOSCFG_PLATFORM))
+    BOARD_NAME := $(subst $/",,$(LOSCFG_PRODUCT_NAME))
+    
+    # 指定SOC进行构建
+    LIB_SUBDIRS += $(LITEOSTOPDIR)/../../device/$(SOC_VENDOR_NAME)/$(SOC_NAME)/drivers/
+    ```
+
+3.  创建SOC驱动构建入口
+
+    ```
+    #文件device/vendor_name/soc_name/drivers/lite.mk
+    
+    SOC_DRIVER_ROOT := $(LITEOSTOPDIR)/../../device/$(SOC_VENDOR_NAME)/$(SOC_NAME)/drivers/
+    
+    # 判断如果打开了GPIO的内核编译开关
+    ifeq ($(LOSCFG_DRIVERS_HDF_PLATFORM_GPIO), y)
+        # 构建完成要链接一个叫hdf_gpio的对象
+        LITEOS_BASELIB += -lhdf_gpio
+        # 增加构建目录gpio
+        LIB_SUBDIRS    += $(SOC_DRIVER_ROOT)/gpio 
+    endif
+    
+    # 后续其他驱动在此基础上追加
+    ```
+
+4.  创建GPIO构建入口
+
+    ```
+    include $(LITEOSTOPDIR)/config.mk
+    include $(LITEOSTOPDIR)/../../drivers/adapter/khdf/liteos/lite.mk
+    
+    # 指定输出对象的名称，注意要与SOC驱动构建入口里的LITEOS_BASELIB 保持一致
+    MODULE_NAME := hdf_gpio
+    
+    # 增加HDF框架的INCLUDE
+    LOCAL_CFLAGS += $(HDF_INCLUDE)
+    
+    # 要编译的文件
+    LOCAL_SRCS += soc_name_gpio.c
+    
+    # 编译参数
+    LOCAL_CFLAGS += -fstack-protector-strong -Wextra -Wall -Werror -fsigned-char -fno-strict-aliasing -fno-common
+    
+    include $(HDF_DRIVER)
+    ```
+
+5.  配置产品加载驱动
+
+    产品的所有设备信息被定义在源码文件//vendor/vendor\_name/product\_name/config/device\_info/device\_info.hcs中。
+
+    平台驱动请添加到platform的host中。
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >moduleName要与驱动定义中的相同。
+
+    ```
+    root {
+        ...
+        platform :: host {
+            device_gpio :: device {
+                    device0 :: deviceNode {
+                        policy = 0;
+                        priority = 10;
+                        permission = 0644;
+                        moduleName = "SOC_NAME_gpio_driver"; 
+                    }
+            }
+        }
+    }
+    ```

+## 移植概述<a name="section14876256185510"></a>
+
+### 移植场景<a name="section1986014410569"></a>
+
+LiteOS-A当前支持ARMv7-a指令集架构，如果三方芯片为ARMv7-a架构，可以进行内核基础适配；否则还需要先根据芯片的架构来新增内核对该芯片架构的支持，这个工作较为复杂，不在这篇文章范围内。
+
+### 目录规范<a name="section10916181716564"></a>
+
+LiteOS-A目录规范参考[LiteOS-A 简介](https://gitee.com/openharmony/kernel_liteos_a)。
+
+## 基础适配<a name="section814974018565"></a>
+
+LiteOS-A提供系统运行所需的系统初始化流程和定制化配置选项。移植过程中，需要关注初始化流程中跟硬件配置相关的函数。
+
+如下图所示，LiteOS-A的初始化流程主要包含以下五步：
+
+1.  新增target\_config.h文件，并且编写单板内存相关的配置宏DDR\_MEM\_ADDR和DDR\_MEM\_SIZE，分别表示内存起始地址和内存的长度，预链接脚本board.ld.S会根据这两个宏进行展开生成链接脚本board.ld。
+2.  链接阶段根据链接脚本board.ld生成内核镜像。
+3.  单核CPU镜像运行入口为汇编文件reset\_vector\_up.S，多核CPU的入口为reset\_vector\_mp.S，在汇编文件中进行中断向量表初始化、MMU页表初始化等操作。
+4.  reset\_vector.S汇编代码最终会跳转到C语言的main函数，进行硬件时钟、软件定时器、内存和任务等初始化，这个过程会依赖target\_config.h的特性宏配置，最后会创建SystemInit任务，并且开启任务调度OsSchedStart\(\)。
+5.  SystemInit任务在单板代码中实现，其中调用DeviceManagerStart函数进行HDF驱动初始化，这个过程会调用单板代码中的驱动配置文件hdf.hcs以及drivers源码实现。
+
+整体启动流程如下图所示：

+
+从图1中可以看到，内核基础适配需要单板进行适配的代码包含三部分：
+
+-   新增target\_config.h文件，其中新增单板硬件配置参数和特性开关的配置参数，具体说明如下：

+
+## 移植概述<a name="section6282121355111"></a>
+
+Linux内核移植主要涉及基于linux内核基线合入三方芯片补丁后，进行基础的内核编译构建及验证。
+
+### 基本信息<a name="section19589322515"></a>
+
+当前Linux内核基线是基于Linux社区 4.19 LTS版本演进，合入CVE及bugfix补丁。具体信息参考[代码库](https://gitee.com/openharmony/kernel_linux)，对应repo工程代码路径为kernel/linux-4.19。
+
+### Bootloader<a name="section19062510518"></a>
+
+可以使用芯片厂商自带的Bootloader，或者是开源Uboot等加载内核镜像。比如为支持Hi3516DV300开发板，OpenHarmony引入的开源[Uboot](https://gitee.com/openharmony/device_hisilicon_third_party_uboot)。
+
+## 适配编译和烧录启动<a name="section11112101695215"></a>
+
+1.  准备内核config（特别是芯片相关的config）。
+
+    config文件所在源码目录：kernel/linux/config/
+
+    以hi3516dv300芯片为例，可在对应的linux-4.19/arch/arm/configs/目录下新建<YOUR\_CHIP\>\_small\_defconfig，如hi3516dv300\_small\_defconfig表示针对hi3516dv300小型系统的defconfig。该config文件可以由基础defconfig文件small\_common\_defconfig与该芯片相关的config组合生成。
+
+2.  准备芯片补丁。
+
+    补丁文件所在源码目录：kernel/linux/patches/linux-4.19
+
+    以hi3516dv300芯片为例，参考已有的patch目录hi3516dv300\_small\_patch目录，新建<YOUR\_CHIP\>\_patch目录，放置相关芯片补丁，注意hdf.patch等驱动补丁。
+
+3.  编译。
+
+    具体内核编译入口脚本位于工程目录kernel/linux/patches/下面，版本级整编命令会通过BUILD.gn进入kernel\_module\_build.sh和kernel.mk，需要在这2个文件中针对性进行patch及defconfig文件路径、编译器、芯片架构、内核Image格式等的适配。
+
+    通过编译错误日志调整补丁，典型错误场景：
+
+    （1）补丁合入失败，出现冲突，需要进行上下文适配修改。
+
+    （2）编译失败，内核版本差异（函数实现调整等）需要针对性进行内核适配。
+
+    >![](../public_sys-resources/icon-caution.gif) **注意：** 
+    >-   参考kernel.mk，在OpenHarmony工程的编译构建流程中会拷贝kernel/linux-4.19的代码环境后进行打补丁动作，在使用版本级编译命令前，需要kernel/linux-4.19保持原代码环境。
+    >-   对应拷贝后的目录位于: out/<\*\*\*\>/kernel/linux-4.19，可以在该目录下进行补丁的修改适配。
+
+4.  烧录启动。
+
+    由于不同芯片的开发板的烧录方式不一样，此处不表述具体的烧录方式。需要注意烧录的各镜像的大小及启动参数的配置，参考hi3516dv300采用uboot启动参数：
+
+    ```
+    setenv bootargs 'mem=128M console=ttyAMA0,115200 root=/dev/mmcblk0p3 ro rootfstype=ext4 rootwait blkdevparts=mmcblk0:1M(boot),9M(kernel),50M(rootfs),50M(userfs)'
+    ```
+
+
+## 验证<a name="section17318153325311"></a>
+
+调试init进程、启动shell和运行简单的用户态程序，验证内核移植是否成功。OpenHarmony[小型系统](https://device.harmonyos.com/cn/docs/start/introduce/oem_start_guide-0000001054913231)的OS镜像结构以及linux用户态的启动流程如下图1所示：
+
+**图 1**  基于linux内核的OS镜像结构和用户态程序启动流程<a name="fig1296918391004"></a>  
+
+
+![](figure/zh-cn_image_0000001126354076.png)
+
+基于上述流程，推荐按以下步骤完成验证：
+
+1.  制作根文件系统镜像。
+
+    请参考[新建芯片解决方案和产品解决方案](https://device.harmonyos.com/cn/docs/develop/subsystems/oem_subsys_build_guide-0000001060378721)生成根文件系统镜像rootfs.img。从上图可以看到启动过程与产品配置强相关，在制作rootfs.img过程中请完成如下四种配置：
+
+    -   组件配置
+
+        产品组件配置文件vendor/\{company\}/\{product\}/config.json需配置启动恢复子系统\(startup\)的init\_lite组件和内核子系统的linux\_4\_1\_9组件。
+
+    -   系统服务配置
+
+        系统服务配置文件vendor/\{company\}/\{product\}/init\_configs/init\_xxx.cfg需要启动shell服务。
+
+    -   文件系统配置
+
+        文件系统配置vendor/\{company\}/\{product\}/fs.yml中需要创建“/bin/sh -\> mksh“和“/lib/ld-musl-arm.so.1 -\> libc.so“软连接，这两个文件分别是shell可执行程序和可执行程序依赖的c库。
+
+    -   启动配置
+
+        启动配置在vendor/\{company\}/\{product\}/init\_configs/etc目录下，包括fstab、rsS和Sxxx文件，请按开发板实际情况配置。
+
+
+    编译完成后，可通过检查产品编译输出目录下的rootfs内容，确认rootfs.img文件生成是否符合预期。
+
+2.  调试init进程和shell。
+
+    烧录rootfs.img并调试init进程和shell，不同厂商的开发板的烧录工具和流程可能不同，请按芯片解决方案提供的流程进行烧录。烧录rootfs.img前请确认bootloader和linux内核启动正常。如果rootfs.img被内核正常挂载，接着将运行/bin/init程序，init进程为用户态的第一个应用程序，它的运行意味着用户态的开始。
+
+    init程序首先会调用/etc/init.d/rcS脚本，rcS脚本执行第一条命令为"/bin/mount -a”，该命令会加载fstab文件，在fstab中的命令执行完后rcS将顺序调用Sxxx脚本完成设备节点创建和扫描、文件权限配置等操作。
+
+    最后，init程序会读取init.cfg系统服务配置文件。根据步骤1中的设置，init程序将会启动shell。如果上述流程运行正常，系统则会进入shell。
+
+    若串口有如下版本号日志打印，则表示init程序启动正常：
+
+    **图 2**  init启动正常日志<a name="fig13510844174415"></a>  
+    
+
+    ![](figure/init.jpg)
+
+    正常进入shell后执行ls命令，串口打印信息如下图：
+
+    **图 3**  正常进入shell后输入ls命令串口打印<a name="fig584415944917"></a>  
+    
+
+    ![](figure/shell.jpg)
+
+3.  配置NFS。
+
+    init进程和shell正常启动后，以服务端IP为192.168.1.22、客户端IP为192.168.1.4为例，可在根目录执行如下命令开启NFS:
+
+    ```
+    ifconfig eth0 192.168.1.4 netmask 255.255.255.0
+    mkdir -p /storgage/nfs
+    mount -t nfs -o nolock,addr=192.168.1.22 192.168.1.22:/nfs /storage/nfs
+    ```

+
+## 新建芯片解决方案<a name="section18612153175011"></a>
+
+了解编译框架和搭建完编译环境后，请参考如下步骤新建芯片解决方案：
+
+1.  <a name="li20894101862"></a>新建目录
+
+    芯片解决方案的目录规则为：device/\{芯片解决方案厂商\}/\{开发板\}。以海思的hispark\_taurus开发板为例，在代码根目录执行如下命令建立目录：
+
+    ```
+    mkdir -p device/hisilicon/hispark_taurus
+    ```
+
+    芯片解决方案目录树的规则如下：
+
+    ```
+    device                                      
+    └── company                         # 芯片解决方案厂商
+        └── board                       # 开发板名称
+            ├── BUILD.gn                # 编译脚本
+            ├── hals                    # OS南向接口适配
+            ├── linux                   # 可选，linux内核版本
+            │   └── config.gni          # linux版本编译配置
+            └── liteos_a                # 可选，liteos内核版本
+                └── config.gni          # liteos_a版本编译配置
+    ```
+
+    以hispark\_taurus移植linux内核为例，目录树应该如下：
+
+    ```
+    device                  
+    └── hisilicon             
+        └── hispark_tautus          
+            ├── BUILD.gn    
+            ├── hals        
+            ├── ......      
+            └── linux    
+                └── config.gni  
+    ```
+
+    目录树建立后开发板相关的源码放到hispark\_taurus目录下。
+
+2.  配置开发板编译选项
+
+    [步骤1](#li20894101862)中的config.gni可配置开发板相关的编译选项，编译构建框架将会遵照该配置文件中的参数编译所有用户态OS组件。其中关键的字段说明如下：
+
+    ```
+    kernel_type:            开发板使用的内核类型，例如：“liteos_a”, “liteos_m”, “linux”。
+    kernel_version:         开发板使用的内核版本，例如：“4.19”。
+    board_cpu:              开发板CPU类型，例如：“cortex-a7”, “riscv32”。
+    board_arch:             开发板芯片arch, 例如： “armv7-a”, “rv32imac”。
+    board_toolchain:        开发板自定义的编译工具链名称，例如：“gcc-arm-none-eabi”。若为空，则使用默认为ohos-clang。
+    board_toolchain_prefix：编译工具链前缀，例如：“gcc-arm-none-eabi”。
+    board_toolchain_type：  编译工具链类型，目前支持gcc和clang。例如：“gcc” ，“clang”。
+    board_cflags：          开发板配置的c文件编译选项。
+    board_cxx_flags：       开发板配置的cpp文件编译选项。
+    board_ld_flags：        开发板配置的链接选项。
+    ```
+
+    还以海思的hispark\_taurus开发板为例，对应的device/hisilicon/hispark\_taurus/config.gni内容如下：
+
+    ```
+    # Board CPU type, e.g. "cortex-a7", "riscv32".
+    board_cpu = "cortex-a7"
+    
+    # Toolchain name used for system compiling.
+    # E.g. gcc-arm-none-eabi, arm-linux-harmonyeabi-gcc, ohos-clang,  riscv32-unknown-elf.
+    # Note: The default toolchain is "ohos-clang". It's not mandatory if you use the default toochain.
+    board_toolchain = "mips-linux-gnu-gcc"
+    
+    # The toolchain path instatlled, it's not mandatory if you have added toolchian path to your ~/.bashrc.
+    board_toolchain_path = 
+        rebase_path("//prebuilts/gcc/linux-x86/arm/arm-linux-ohoseabi-gcc/bin",
+                    root_build_dir)
+    
+    # Compiler prefix.
+    board_toolchain_prefix = "arm-linux-ohoseabi-"
+    
+    # Compiler type, "gcc" or "clang".
+    board_toolchain_type = "gcc"
+    
+    # Board related common compile flags.
+    board_cflags = [
+    ]
+    board_cxx_flags = [
+    ]
+    board_ld_flags = []
+    
+    # Board related headfiles search path.
+    board_include_dirs = []
+    board_include_dirs += [ rebase_path(
+            "//prebuilts/gcc/linux-x86/arm/arm-linux-ohoseabi-gcc/target/usr/include",
+            root_build_dir) ]
+    
+    # Board adapter dir for OHOS components.
+    board_adapter_dir = ""
+    
+    # Sysroot path.
+    board_configed_sysroot = ""
+    
+    # Board storage type, it used for file system generation.
+    storage_type = "emmc"
+    ```
+
+3.  编写开发板编译脚本
+
+    步骤1中的BUILD.gn为新增的开发板的编译入口，主要用于编译开发板相关的代码，主要为设备侧驱动、设备侧接口适配\(媒体，图形等\)和开发板的SDK等等。
+
+    海思的hispark\_taurus开发板的device/hisilicon/hispark\_taurus/BUILD.gn可写成：
+
+    ```
+    # group名称建议与开发板名称一致
+    group("hispark_taurus") {   
+      deps = [ "//kernel/linux/patches:linux_kernel" ] # 拉起内核编译
+      deps += [
+      ...... # 开发板其他编译单元
+      ]
+    }
+    ```
+
+4.  编译调试
+
+    在开发板目录下执行hb set和hb build即可启动芯片解决方案的编译，编译框架会以开发板下的BUILD.gn为入口启动编译。

+## 移植思路<a name="section9737174410328"></a>
+
+移植思路：通过修改工具链，交叉编译该三方库，生成OpenHarmony平台的可执行文件，最后再通过GN调用CMake的方式添加到OpenHarmony工程中。
+
+## 交叉编译<a name="section38205577332"></a>
+
+### 编译参考<a name="section1088111263418"></a>
+
+代码仓库的[README.md](https://github.com/google/double-conversion/blob/master/README.md)中详细介绍了使用CMake编译double-conversion库的步骤，以及测试方法。本文参考该指导设置该库的编译配置，并完成测试。若开发人员在移植过程中对该库的编译选项配置有疑惑的地方，可参考该指导。对于其他使用CMake可独立编译的三方库，在移植时可以参考其自带的编译指导。
+
+### 设置执行交叉编译<a name="section8168182883515"></a>
+
+CMake方式可通过指定工具链进行交叉编译，修改并编译该库，生成OpenHarmony平台的可执行文件，步骤如下：
+
+1.  设置工具链
+
+    将下列clang工具链配置添加到该工程的顶层CMakeLists.txt（即[表1中的该文件](#table824211132418)）中即可。
+
+    ```
+    set(CMAKE_CROSSCOMPILING TRUE)
+    set(CMAKE_SYSTEM_NAME Generic)
+    set(CMAKE_CXX_COMPILER_ID Clang)
+    set(CMAKE_TOOLCHAIN_PREFIX llvm-)
+    #指定c编译工具（确保工具链所在路径已经添加到了PATH环境变量中）和编译标志，使用clang编译时标志中必须指定--target，否则无法交叉编译。
+    set(CMAKE_C_COMPILER clang)
+    set(CMAKE_C_FLAGS "--target=arm-liteos -D__clang__ -march=armv7-a -w")
+    #指定c++编译工具（确保工具链所在路径已经添加到了PATH环境变量中）和编译标志，必须指定--target，否则无法交叉编译。
+    set(CMAKE_CXX_COMPILER clang++) 
+    set(CMAKE_CXX_FLAGS "--target=arm-liteos -D__clang__ -march=armv7-a -w")
+    #指定链接工具和链接标志，必须指定--target和--sysroot，其中OHOS_ROOT_PATH可通过cmake命令后缀参数来指定。
+    set(MY_LINK_FLAGS "--target=arm-liteos --sysroot=${OHOS_SYSROOT_PATH}")
+    set(CMAKE_LINKER clang)
+    set(CMAKE_CXX_LINKER clang++)
+    set(CMAKE_C_LINKER clang)
+    set(CMAKE_C_LINK_EXECUTABLE "${CMAKE_C_LINKER}
+    ${MY_LINK_FLAGS} <FLAGS> <LINK_FLAGS> <OBJECTS> -o <TARGET> <LINK_LIBRARIES>")
+    set(CMAKE_CXX_LINK_EXECUTABLE "${CMAKE_CXX_LINKER}
+    ${MY_LINK_FLAGS} <FLAGS> <LINK_FLAGS> <OBJECTS> -o <TARGET> <LINK_LIBRARIES>")
+    #指定链接库的查找路径。
+    set(CMAKE_SYSROOT ${OHOS_SYSROOT_PATH})
+    ```
+
+2.  执行编译
+
+    linux命令行中进入double-conversion的源文件目录（即[表1所示目录](#table824211132418)），执行下列命令：
+
+    ```
+    mkdir build && cd build
+    cmake .. -DBUILD_TESTING=ON -DOHOS_SYSROOT_PATH="..."
+    make -j
+    ```
+
+    其中OHOS\_SYSROOT\_PATH需用绝对路径指定出sysroot目录的位置，以OpenHarmony为例即目录openHarmony/prebuilts/lite/sysroot的绝对路径。
+
+3.  <a name="li15717101715249"></a>查看结果
+
+    步骤2操作完成后，build目录下会生成静态库文件和测试用例：

+
+1.  搭建OpenHarmony环境
+
+    以hi3518ev300为例，编译出OpenHarmony镜像，烧写到开发板，参考[开发Hi3518第一个示例程序](../quick-start/quickstart-lite-steps-board3518-running.md)。
+
+    进入系统如下所示：

+    **图 1**  OpenHarmony启动成功界面<a name="fig13279524162418"></a>  
+    ![](figure/OpenHarmony启动成功界面.png "OpenHarmony启动成功界面")
+
+2.  挂载nfs目录，将[表2](#table1452412391911)中test目录下cctest可执行文件放入nfs目录
+3.  执行用例
+
+    该库采用非交叉编译时用例是通过make test执行，CMake会有相关的执行结果统计；交叉编译时无法使用该方法，因此可直接执行生成的测试文件完成测试。
+
+    -   挂载成功后执行下列命令可列出用例所有条目：
+
+    ```
+    cd nfs
+    ./cctest --list

+## 将该库编译添加到OpenHarmony工程中<a name="section1651053153715"></a>
+
+1.  复制库到OpenHarmony工程中
+
+    拷贝已经能够成功交叉编译的库到OpenHarmony的third\_party目录，为了不修改要移植的三方库目录下的BUILD.gn文件，再添加一层目录放置新增的gn转CMake编译适配文件，新增的文件有BUILD.gn、build\_thirdparty.py、 config.gni，新增后的目录结构如下所示。

+2.  添加gn到CMake适配文件
+
+    -   **新增的BUILD.gn文件实现如下，其他采用CMake方式可独立编译的三方库移植到OpenHarmony平台时只需修改路径即可**。
+
+    ```
+    import("config.gni")
+    group("double-conversion") {

+                "--path=$exec_path",
+                "--command=${command}"
+            ]
+        }
+    }
+    ```
+
+    -   **新增的config.gni用于配置该库，实现如下，其他采用CMake方式可独立编译的三方库移植到OpenHarmony时只需修改CMAKE\_FLAG的配置即可。**
+
+    ```
+    #CMAKE_FLAG: config compile feature
+    CMAKE_FLAG = "-DBUILD_TESTING=ON -DCMAKE_CXX_STANDARD=11"
+    
+    #toolchain：follow up-layer，depend on $ohos_build_compiler

+    } else {
+        CMAKE_TOOLCHAIN_FLAG = ""
+    }
+    
+    #CMake tools path,no need setting if this path already joined to $PATH.
+    CMAKE_TOOLS_PATH = "setting CMake tools path..."
+    ```
+
+    -   **新增的build\_thirdparty.py实现如下，其他采用CMake方式可独立编译的三方库移植到OpenHarmony时无需修改即可使用。**
+
+    ```
+    import os
+    import sys
+    from subprocess import Popen
+    import argparse
+    import shlex
+    
+    def cmd_exec(command):
+        cmd = shlex.split(command)
+        proc = Popen(cmd)
+        proc.wait()
+        ret_code = proc.returncode
+        if ret_code != 0:
+            raise Exception("{} failed, return code is {}".format(cmd, ret_code))
+    
+    def main():
+        parser = argparse.ArgumentParser()
+        parser.add_argument('--path', help='Build path.')

+        if args.path:
+            curr_dir = os.getcwd()
+            os.chdir(args.path)
+            if args.command:
+                if '&&' in args.command:
+                    command = args.command.split('&&')
+                    for data in command:
+                        cmd_exec(data)
+                else:
+                    cmd_exec(args.command)
+            os.chdir(curr_dir)
+    
+    if __name__ == '__main__':
+        sys.exit(main())
+    ```
+
+    -   在配置文件中添加开关控制该库编译，默认设为关闭
+
+    在//build/lite/ohos\_var.gni文件中添加下列配置：
+
+    ```
+    declare_args() {
+        ohos_build_thirdparty_migrated_from_fuchisa = true
+    }
+    ```
+
+3.  编译构建
+
+    -   手动单独构建：
+
+    执行下列命令
+
+    ```
+    hb build -T //third_party/double-conversion:double-conversion
+    ```
+
+    编译成功则[build](#li15717101715249)目录下会生成静态库文件和测试用例

+## 设置交叉编译<a name="section81263255384"></a>
+
+设置Makefile的交叉编译工具链，修改并编译该库，生成OpenHarmony平台的可执行文件，步骤如下：
+
+1.  设置工具链
+
+    将下列clang工具链配置替换掉yxml库根目录的MakeFile（即[表1中的文件](#table16520154171813)）中的原有配置。
+
+    clang工具链配置
+
+    ```
+    #设置交叉编译工具链，确保工具链所在路径已经添加到了PATH环境变量中
+    CC:=clang
+    AR:=llvm-ar
+    #cflags中必须要添加--target及--sysroot选项
+    CFLAGS:=-Wall -Wextra -Wno-unused-parameter -O2 -g --target=arm-liteos -march=armv7-a --sysroot=$(OHOS_ROOT_PATH)prebuilts/lite/sysroot
+    ```
+
+    原有配置
+
+    ```
+    CC:=gcc
+    AR:=ar
+    CFLAGS:=-Wall -Wextra -Wno-unused-parameter -O2 -g
+    ```
+
+2.  执行编译
+
+    linux命令行中进入yxml的源文件目录（即图1所示目录），执行下列命令：
+
+    ```
+    make test OHOS_SYSROOT_PATH=...
+    ```
+
+    其中OHOS\_SYSROOT\_PATH需用绝对路径指定出sysroot所在目录，以OpenHarmony为例即源码根目录prebuilts/lite/sysroot/所在的绝对路径。
+
+3.  查看结果
+
+    步骤2操作完成后，yxml下会生成out目录，里面有静态库文件和测试用例：
+
+    **表 2**  yxml编译生成目录

+echo "All tests completed successfully."
+```
+
+由于OpenHarmony的shell中暂不支持输入输出重定向（<和\>），所以测试时需要将输入\*.xml文件内容直接复制进shell后回车，输出内容会直接展示在shell窗口。过程如下：
+
+下列操作假定已按照2.4节的步骤搭建OpenHarmony，挂载并进入nfs目录：
+
+1.  执行下列命令
+
+    ```
+    ./test
+    ```
+
+2.  复制\*.xml内容到shell
+
+    以[test目录](#table115941423164318)下pi01.xml为例，内容如下，输入到shell并回车：
+
+    ```
+    <?SomePI abc?><a/>
+    ```
+
+3.  比较shell中输出的内容与[test目录](#table115941423164318)中对应的\*.out文件是否一致
+
+    输出结果如下：
+
+    ```
+    pistart SomePI
+    picontent abc
+    piend
+    elemstart a
+    elemend

-# 三方组件适配<a name="ZH-CN_TOPIC_0000001117478960"></a>
-
-如果需要使用third\_party目录下与产品相关的三方组件，可能需要对三方组件进行适配，下面以比较常用的mbedtls为例，介绍下适配步骤，注意本小节中仅介绍如何将适配的代码与OpenHarmony的编译框架融合，不会详细介绍mbedtls本身的原理和适配代码的具体逻辑，这些内容请参考mbedtls官方网站上的适配指南。
-
-1.  编写适配层代码
-
-    根据mbedtls官网的适配指南，编写需要的适配层代码，以适配硬件随机数举例，下面的路径都是相对third\_party/mbedtls的路径：
-
-    1.  拷贝include/mbedtls/config.h到ports目录下，并修改打开MBEDTLS\_ENTROPY\_HARDWARE\_ALT开关。
-    2.  在ports目录下创建entropy\_poll\_alt.c文件include并实现entropy\_poll.h中的硬件随机数接口
-    3.  在BUILD.gn中的mbedtls\_sources中增加刚才适配的entropy\_poll\_alt.c的路径
-    4.  在BIULD.gn中的lite\_library\("mbedtls\_static"\)中增加一行MBEDTLS\_CONFIG\_FILE指定新配置文件的位置
-
-        ```
-        lite_library("mbedtks_static") {
-          ...  
-          defines += ["MBEDTLS_CONFIG_FILE=<../port/config.h>"]
-          ...
-        }
-        ```
-
-
-    注意，上面的修改最好都新建一个config或者新建一个xxx\_alt.c文件来修改，不要直接在原先的代码中修改，侵入式的修改会导致后续版本升级出现大量零散冲突，增加升级维护成本。
-
-2.  制作patch
-
-    由于上面的适配是硬件相关的，上库代码时，不能直接放到通用的third\_party/mbedtls目录中，因此需要将上面的修改制作成patch，在编译之前通过打patch的方式注入到代码中。
-
-    1.  首先增加设备的patch配置文件device/<company\>/<board\>/patch.yml
-    2.  编辑device/<company\>/<board\>/patch.yml，增加要打的patch的信息：
-
-        ```
-        # 需要打patch的路径，路径均为相对代码根目录的路径
-        third_party/mbedtls:
-          # 该路径下需要打的patch存放路径
-          - device/<company>/<board>/third_party/mbedtls/adapter.patch
-        third_party/wpa_supplicant:
-          # 当一个路径下有多个patch的时候会依次执行patch
-          - device/<company>/<board>/third_party/wpa_supplicant/xxxxx.patch
-          - device/<company>/<board>/third_party/wpa_supplicant/yyyyy.patch
-        ...
-        ```
-
-    3.  制作上述**步骤1**修改的patch并放到对应的目录即可
-
-3.  使用带patch的编译
-
-    想要在编译的时候带上patch，其他步骤不变，仅需要在触发编译的时候加上 --patch，例如全编译的命令编程
-
-    ```
-    hb build -f --patch
-    ```
-
-    >![](public_sys-resources/icon-caution.gif) **注意：** 
-    >最后一次打patch的产品信息会被记录，在进行下一次编译操作时，会对上一次的patch进行回退（即执行\`patch -p1 -R < xxx\`），回退patch失败或新增patch失败均会终止编译过程，请解决patch冲突后再次尝试编译。

--   [特性配置项](#section112994366592)
-
-芯片架构适配完成后，liteos-m提供系统运行所需的系统初始化流程和定制化配置选项。移植过程中，需要关注初始化流程中跟硬件配置相关的函数；了解内核配置选项，才能裁剪出适合单板的最小内核。
-
-## 基础适配<a name="section14523241594"></a>
-
-如下图所示，基础适配主要分为以下两步：
-
-1.  启动文件startup.S和相应链接配置文件。
-2.  main. c中的串口初始化和tick中断注册。
-
-**图 1**  启动流程<a name="fig10838105524917"></a>  
-
-
-![](figures/zh-cn_image_0000001073943511.png)
-
-启动文件startup.S需要确保中断向量表的入口函数（例如reset\_vector）放在RAM的首地址，它由链接配置文件来指定。其中iar、keil和gcc工程的链接配置文件分别为xxx.icf、xxx.sct和xxx.ld，如果startup.S已经完成系统时钟初始化，并且能够引导到main函数，则启动文件不需要进行修改，采用厂商自带的startup.S即可，否则需要实现以上功能。
-
-在main.c文件中，需要关注串口初始化UartInit和系统Tick的handler函数注册。
-
--   UartInit函数表示单板串口的初始化，具体的函数名根据单板自行定义。这个函数是可选的，用户可以根据硬件单板是否支持串口来自行选择调用该函数。如果硬件单板支持串口，则该函数需要完成使能串口TX和RX通道，设置波特率。
--   HalTickStart设置tick中断的handler函数OsTickHandler。
-
-对于中断向量表不可重定向的芯片，需要关闭LOSCFG\_PLATFORM\_HWI宏，并且在startup.S中新增tick中断的handler函数。
-
-## 特性配置项<a name="section112994366592"></a>
-
-liteos\_m的完整配置能力及默认配置在los\_config.h定义，该头文件中的配置项可以根据不同的单板进行裁剪配置。
-
-如果针对这些配置项需要进行不同的板级配置，则可将对应的配置项直接定义到对应单板的device/xxxx/target\_config.h文件中，其他未定义的配置项，采用los\_config.h中的默认值。
-
-一份典型的配置参数如下：

-在工程device目录下添加编译main.c示例程序文件，此示例程序的主要目的是：LOS\_KernelInit完成之后，创建两个任务，循环调度延时并打印日志信息，通过此方法可以验证系统是否可正常调度以及时钟是否正常。

-第一个任务运行正常后，说明最小系统的核心流程基本OK；由于xts用例框架对外依赖较多，主要是utils、bootstrap的链接脚本和编译框架，暂时无法支撑内核单独跑xts；此处略过内核测试套的测试，可以通过[XTS测试套](XTS认证.md)来覆盖最小系统是否完整移植成功。

-芯片架构适配是可选过程，如果在liteos\_m/kernel/arch目录下已经支持对应芯片架构，则可以跳过芯片架构适配，进行单板适配过程，否则需要进行芯片架构移植工作。
-
-## 目录规范<a name="section18127744153119"></a>
-
-模组芯片使用的内核为liteos-m，liteos-m中主要分为KAL、Components、Kernel和Utils四个模块。
-
--   KAL模块作为内核对外的接口依赖Components模块和Kernel模块。
--   Components模块可插拔，它依赖Kernel模块。
-
--   在Kernel模块中，其中硬件相关的代码放在kernel的arch目录中，其余为硬件无关的代码。内核功能集（task、sem等）的实现依赖硬件相关的arch代码，例如任务上下文切换、原子操作等。
--   Utils模块作为基础代码块，被其他模块依赖。

-内核的目录结构和说明如下：
-
-```
-.

-
-## 芯片架构适配点<a name="section137431650339"></a>
-
-如内核的[目录结构](#section18127744153119)所示，arch/include定义通用的芯片架构所需要实现的函数，另外芯片架构相关的代码会有部分的汇编代码，而汇编代码会因编译工具链的不同而不同，因此在具体的芯片架构下，还包含不同工具链（iar、keil、gcc等）的实现。
-
-arch/include 目录定义通用的文件以及函数列表，该目录下的所有函数在新增arch组件时都需要适配，详见每一个头文件：
-
-```
-los_arch.h                        --- 定义芯片架构初始化所需要的函数
-los_atomic.h                      --- 定义芯片架构所需要实现的原子操作函数
-los_context.h                     --- 定义芯片架构所需要实现的任务上下文相关函数
-los_interrupt.h                   --- 定义芯片架构所需要实现的中断和异常相关的函数
-los_timer.h                       --- 定义芯片架构所需要实现的系统时钟相关的函数
-```

-本文为OpenHarmony平台系统开发人员和芯片（或模组）制造商提供基础的开发移植指导，典型的芯片架构例如cortex-m系列、risc-v系列等都可以按照本文进行移植，暂时不支持蓝牙服务。OpenHarmony是个持续演进的复杂项目，随着版本和API的改变，本文将会不断更新。
-
-本文要求读者具有一定的嵌入式系统开发经验，因此它的重点未放在基本的OS基础介绍，而更多地描述OpenHarmony平台移植过程中主要操作和所需要关注的方面。
-
-## 移植目录<a name="section284217487490"></a>

->![](public_sys-resources/icon-notice.gif) **须知：** 
->-   针对Ubuntu编译环境我们提供了对应的Docker，该Docker封装了相关编译工具，选择使用Docker的开发者可跳过此章节。Docker使用可参考[Docker方式获取编译环境](../get-code/Docker编译环境.md)。
->-   通常系统默认安装samba、vim等常用软件，需要做适当适配以支持Linux服务器与Windows工作台之间的文件共享。
->-   想要详细了解OpenHarmony编译构建模块功能的开发者可参考[编译构建使用指南](../subsystems/编译构建.md)。

-完成版本构建及烧录后，下面开始介绍如何在串口终端上执行AT命令，使WLAN模组联网。
-
-1.  保持Windows工作台和WLAN模组的连接状态，在DevEco工具最下方，点击“DevEco:Serial Monitor”按钮。
-
-    **图 7**  打开DevEco串口终端示意图<a name="fig12489182991119"></a>  
-    
-
-    ![](figures/5-1.png)
-
-2.  复位WLAN模组，终端界面显示“ready to OS start”，则启动成功。

-    ![](figures/6.png)
-
-3.  在DevEco的串口终端中，依次执行如下AT命令，启动STA模式，连接指定AP热点，并开启DHCP功能。
-
-    ```
-    AT+STARTSTA                             # 启动STA模式
-    AT+SCAN                                 # 扫描周边AP
-    AT+SCANRESULT                           # 显示扫描结果
-    AT+CONN="SSID",,2,"PASSWORD"            # 连接指定AP，其中SSID/PASSWORD为待连接的热点名称和密码
-    AT+STASTAT                              # 查看连接结果
-    AT+DHCP=wlan0,1                         # 通过DHCP向AP请求wlan0的IP地址
-    ```
-
-4.  查看WLAN模组与网关联通是否正常，如下图所示。
-
-    ```
-    AT+IFCFG                                # 查看模组接口IP
-    AT+PING=X.X.X.X                         # 检查模组与网关的联通性，其中X.X.X.X需替换为实际的网关地址
-    ```

+>-   针对Ubuntu编译环境我们提供了对应的Docker，该Docker封装了相关编译工具，选择使用Docker的开发者可跳过此章节。Docker使用可参考[Docker方式获取编译环境](../get-code/gettools-acquire.md)。
+>-   通常系统默认安装samba、vim等常用软件，需要做适当适配以支持Linux服务器与Windows工作台之间的文件共享。
+>-   想要详细了解OpenHarmony编译构建模块功能的开发者可参考[编译构建使用指南](../subsystems/subsys-build-mini-lite.md)。

+
+本节指导开发者在单板上运行第一个驱动程序，其中包括驱动程序介绍、编译、烧写、运行等步骤。
+
+## 驱动程序介绍<a name="s8efc1952ebfe4d1ea717182e108c29bb"></a>
+
+下面基于HDF框架，提供一个简单的UART（Universal Asynchronous Receiver/Transmitter）平台驱动开发样例，包含配置文件的添加，驱动代码的实现以及用户态程序和驱动交互的流程。驱动程序源码位于vendor/huawei/hdf/sample目录
+
+1.  添加配置。
+
+    在HDF框架的驱动配置文件（例如device/hisilicon/hi3516dv300/sdk\_liteos/config/uart/uart\_config.hcs）中添加该驱动的配置信息，如下所示：
+
+    ```
+    root {
+        platform {
+            uart_sample {
+                num = 5;            // UART设备编号
+                base = 0x120a0000;  // UART 寄存器基地址
+                irqNum = 38;
+                baudrate = 115200;
+                uartClk = 24000000;
+                wlen = 0x60;
+                parity = 0;
+                stopBit = 0;
+                match_attr = "sample_uart_5";
+            }
+        }
+    }
+    ```
+
+    在HDF框架的设备配置文件（例如vendor/hisilicon/ipcamera\_hi3516dv300\_liteos/config/device\_info/device\_info.hcs）中添加该驱动的设备节点信息，如下所示：
+
+    ```
+    root {
+        device_info {
+            platform :: host {
+                hostName = "platform_host";
+                priority = 50;
+                device_uart :: device {
+                    device5 :: deviceNode {
+                        policy = 2;
+                        priority = 10;
+                        permission = 0660;
+                        moduleName = "UART_SAMPLE";
+                        serviceName = "HDF_PLATFORM_UART_5";
+                        deviceMatchAttr = "sample_uart_5";
+                    }
+                }
+            }
+        }
+    }
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >配置文件与UART驱动示例的源码在同一个路径，需要手动添加到Hi3516DV300单板路径下。
+
+2.  注册UART驱动入口。
+
+    基于HDF框架注册UART驱动的入口HdfDriverEntry，代码如下：
+
+    ```
+    // 绑定UART驱动接口到HDF框架
+    static int32_t SampleUartDriverBind(struct HdfDeviceObject *device)
+    {
+        struct UartHost *uartHost = NULL;
+    
+        if (device == NULL) {
+            return HDF_ERR_INVALID_OBJECT;
+        }
+        HDF_LOGI("Enter %s:", __func__);
+    
+        uartHost = UartHostCreate(device);
+        if (uartHost == NULL) {
+            HDF_LOGE("%s: UartHostCreate failed", __func__);
+            return HDF_FAILURE;
+        }
+        uartHost->service.Dispatch = SampleDispatch;
+        return HDF_SUCCESS;
+    }
+     
+    // 从UART驱动的HCS中获取配置信息
+    static uint32_t GetUartDeviceResource(
+        struct UartDevice *device, const struct DeviceResourceNode *resourceNode)
+    {
+        struct UartResource *resource = &device->resource;
+        struct DeviceResourceIface *dri = NULL;
+        dri = DeviceResourceGetIfaceInstance(HDF_CONFIG_SOURCE);
+        if (dri == NULL || dri->GetUint32 == NULL) {
+            HDF_LOGE("DeviceResourceIface is invalid");
+            return HDF_FAILURE;
+        }

+    };
+     
+    HDF_INIT(g_sampleUartDriverEntry);
+    ```
+
+3.  注册UART驱动接口。
+
+    HDF框架提供了UART驱动接口的模板方法UartHostMethod，实现UART驱动接口的代码如下：
+
+    ```
+    static int32_t SampleUartHostInit(struct UartHost *host)
+    {
+        HDF_LOGI("%s: Enter", __func__);
+        if (host == NULL) {
+            HDF_LOGE("%s: invalid parameter", __func__);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        return HDF_SUCCESS;
+    }
+    
+    static int32_t SampleUartHostDeinit(struct UartHost *host)
+    {
+        HDF_LOGI("%s: Enter", __func__);
+        if (host == NULL) {
+            HDF_LOGE("%s: invalid parameter", __func__);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        return HDF_SUCCESS;
+    }
+    
+    // 向UART中写入数据
+    static int32_t SampleUartHostWrite(struct UartHost *host, uint8_t *data, uint32_t size)
+    {
+        HDF_LOGI("%s: Enter", __func__);
+        uint32_t idx;
+        struct UartRegisterMap *regMap = NULL;
+        struct UartDevice *device = NULL;
+    
+        if (host == NULL || data == NULL || size == 0) {
+            HDF_LOGE("%s: invalid parameter", __func__);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        device = (struct UartDevice *)host->priv;
+        if (device == NULL) {
+            HDF_LOGE("%s: device is NULL", __func__);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        regMap = (struct UartRegisterMap *)device->resource.physBase;
+        for (idx = 0; idx < size; idx++) {
+            UartPl011Write(regMap, data[idx]);
+        }
+        return HDF_SUCCESS;
+    }
+     
+    // 设置UART的波特率
+    static int32_t SampleUartHostSetBaud(struct UartHost *host, uint32_t baudRate)
+    {
+        HDF_LOGI("%s: Enter", __func__);
+        struct UartDevice *device = NULL;
+        struct UartRegisterMap *regMap = NULL;
+        UartPl011Error err;
+    
+        if (host == NULL) {
+            HDF_LOGE("%s: invalid parameter", __func__);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        device = (struct UartDevice *)host->priv;
+        if (device == NULL) {
+            HDF_LOGE("%s: device is NULL", __func__);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        regMap = (struct UartRegisterMap *)device->resource.physBase;
+        if (device->state != UART_DEVICE_INITIALIZED) {
+            return UART_PL011_ERR_NOT_INIT;
+        }
+        if (baudRate == 0) {
+            return UART_PL011_ERR_INVALID_BAUD;
+        }
+        err = UartPl011SetBaudrate(regMap, device->uartClk, baudRate);
+        if (err == UART_PL011_ERR_NONE) {
+            device->baudrate = baudRate;
+        }
+        return err;
+    }
+     
+    // 获取UART的波特率
+    static int32_t SampleUartHostGetBaud(struct UartHost *host, uint32_t *baudRate)
+    {
+        HDF_LOGI("%s: Enter", __func__);
+        struct UartDevice *device = NULL;
+    
+        if (host == NULL) {
+            HDF_LOGE("%s: invalid parameter", __func__);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        device = (struct UartDevice *)host->priv;
+        if (device == NULL) {
+            HDF_LOGE("%s: device is NULL", __func__);
+            return HDF_ERR_INVALID_PARAM;
+        }
+        *baudRate = device->baudrate;
+        return HDF_SUCCESS;
+    }
+     
+    // 在HdfUartSampleInit方法中绑定
+    struct UartHostMethod g_sampleUartHostMethod = {
+        .Init = SampleUartHostInit,
+        .Deinit = SampleUartHostDeinit,
+        .Read = NULL,
+        .Write = SampleUartHostWrite,
+        .SetBaud = SampleUartHostSetBaud,
+        .GetBaud = SampleUartHostGetBaud,
+        .SetAttribute = NULL,
+        .GetAttribute = NULL,
+        .SetTransMode = NULL,
+    };
+    ```
+
+    在device/hisilicon/drivers/lite.mk编译脚本中增加示例UART驱动模块，代码如下：
+
+    ```
+    LITEOS_BASELIB += -lhdf_uart_sample
+    LIB_SUBDIRS    += $(LITEOS_SOURCE_ROOT)/vendor/huawei/hdf/sample/platform/uart
+    ```
+
+4.  用户程序和驱动交互代码。
+
+    UART驱动成功初始化后，会创建/dev/uartdev-5设备节点，通过设备节点与UART驱动交互的代码如下：
+
+    ```
+    #include <stdlib.h>
+    #include <unistd.h>
+    #include <fcntl.h>
+    #include "hdf_log.h"
+    
+    #define HDF_LOG_TAG "hello_uart"
+    #define INFO_SIZE 16
+    
+    int main(void)
+    {
+        int ret;
+        int fd;
+        const char info[INFO_SIZE] = {" HELLO UART! "};
+    
+        fd = open("/dev/uartdev-5", O_RDWR);
+        if (fd < 0) {
+            HDF_LOGE("hello_uart uartdev-5 open failed %d", fd);
+            return -1;
+        }
+        ret = write(fd, info, INFO_SIZE);
+        if (ret != 0) {
+            HDF_LOGE("hello_uart write uartdev-5 ret is %d", ret);
+        }
+        ret = close(fd);
+        if (ret != 0) {
+            HDF_LOGE("hello_uart uartdev-5 close failed %d", fd);
+            return -1;
+        }
+        return ret;
+    }
+    ```
+
+    在build/lite/components/drivers.json驱动配置中hdf\_hi3516dv300\_liteos\_a组件下的targets中增加hello\_uart\_sample组件，代码如下：
+
+    ```
+    {
+      "components": [
+        {
+          "component": "hdf_hi3516dv300_liteos_a",
+          ...
+          "targets": [
+            "//vendor/huawei/hdf/sample/platform/uart:hello_uart_sample"
+          ]
+        }
+      ]
+    }
+    ```

+
+本节指导开发者在单板上运行第一个应用程序，其中包括新建应用程序、编译、烧写、运行等步骤，最终输出“Hello OHOS！”。
+
+## 新建应用程序<a name="section204672145202"></a>
+
+1.  新建目录及源码
+
+    新建**applications/sample/camera/apps/src/helloworld.c**目录及文件，代码如下所示，用户可以自定义修改打印内容（例如：修改OHOS为World）。当前应用程序可支持标准C及C++的代码开发。
+
+    ```
+    #include <stdio.h>
+    
+    int main(int argc, char **argv)
+    {
+        printf("\n************************************************\n");
+        printf("\n\t\tHello OHOS!\n");
+        printf("\n************************************************\n\n");
+    
+        return 0;
+    }
+    ```
+
+2.  新建编译组织文件
+
+    新建**applications/sample/camera/apps/BUILD.gn**文件，内容如下所示：
+
+    ```
+    import("//build/lite/config/component/lite_component.gni")
+    lite_component("hello-OHOS") {
+      features = [ ":helloworld" ]
+    }
+    executable("helloworld") {
+      output_name = "helloworld"
+      sources = [ "src/helloworld.c" ]
+      include_dirs = []
+      defines = []
+      cflags_c = []
+      ldflags = []
+    }
+    ```
+
+3.  添加新组件
+
+    修改文件**build/lite/components/applications.json**，添加组件hello\_world\_app的配置，如下所示为applications.json文件片段，"\#\#start\#\#"和"\#\#end\#\#"之间为新增配置（"\#\#start\#\#"和"\#\#end\#\#"仅用来标识位置，添加完配置后删除这两行）：
+
+    ```
+    {
+      "components": [
+        {
+          "component": "camera_sample_communication",
+          "description": "Communication related samples.",
+          "optional": "true",
+          "dirs": [
+            "applications/sample/camera/communication"
+          ],
+          "targets": [
+            "//applications/sample/camera/communication:sample"
+          ],
+          "rom": "",
+          "ram": "",
+          "output": [],
+          "adapted_kernel": [ "liteos_a" ],
+          "features": [],
+          "deps": {
+            "components": [],
+            "third_party": []
+          }
+        },
+    ##start##
+        {
+          "component": "hello_world_app",
+          "description": "Communication related samples.",
+          "optional": "true",
+          "dirs": [
+            "applications/sample/camera/apps"
+          ],
+          "targets": [
+            "//applications/sample/camera/apps:hello-OHOS"
+          ],
+          "rom": "",
+          "ram": "",
+          "output": [],
+          "adapted_kernel": [ "liteos_a" ],
+          "features": [],
+          "deps": {
+            "components": [],
+            "third_party": []
+          }
+        },
+    ##end##
+        {
+          "component": "camera_sample_app",
+          "description": "Camera related samples.",
+          "optional": "true",
+          "dirs": [
+            "applications/sample/camera/launcher",
+            "applications/sample/camera/cameraApp",
+            "applications/sample/camera/setting",
+            "applications/sample/camera/gallery",
+            "applications/sample/camera/media"
+          ],
+    ```
+
+4.  修改单板配置文件
+
+    修改文件**vendor/hisilicon/hispark\_taurus/config.json**，新增hello\_world\_app组件的条目，如下所示代码片段为applications子系统配置，"\#\#start\#\#"和"\#\#end\#\#"之间为新增条目（"\#\#start\#\#"和"\#\#end\#\#"仅用来标识位置，添加完配置后删除这两行）：
+
+    ```
+          {
+            "subsystem": "applications",
+            "components": [
+              { "component": "camera_sample_app", "features":[] },
+              { "component": "camera_sample_ai", "features":[] },
+    ##start##
+              { "component": "hello_world_app", "features":[] },
+    ##end##
+              { "component": "camera_screensaver_app", "features":[] }
+            ]
+          },
+    ```
+
+
+## 编译<a name="section1077671315253"></a>
+
+如果Linux编译环境通过Docker方式安装，具体编译过程请参见[Docker方式获取编译环境](../get-code/gettools-acquire.md)的编译操作。如果Linux编译环境通过软件包方式安装，请进入源码根目录，执行如下命令进行编译：
+
+```

+
+本节指导开发者在单板上运行第一个应用程序，其中包括新建应用程序、编译、烧写、运行等步骤，最终输出“Hello OHOS！”。
+
+## 新建应用程序<a name="section1550972416485"></a>
+
+1.  新建目录及源码
+
+    新建**applications/sample/camera/apps/src/helloworld.c**目录及文件，代码如下所示，用户可以自定义修改打印内容（例如：修改OHOS为World）。当前应用程序可支持标准C及C++的代码开发。
+
+    ```
+    #include <stdio.h>
+    
+    int main(int argc, char **argv)
+    {
+        printf("\n************************************************\n");
+        printf("\n\t\tHello OHOS!\n");
+        printf("\n************************************************\n\n");
+    
+        return 0;
+    }
+    ```
+
+2.  新建编译组织文件
+
+    新建**applications/sample/camera/apps/BUILD.gn**文件，内容如下所示：
+
+    ```
+    import("//build/lite/config/component/lite_component.gni")
+    lite_component("hello-OHOS") {
+      features = [ ":helloworld" ]
+    }
+    executable("helloworld") {
+      output_name = "helloworld"
+      sources = [ "src/helloworld.c" ]
+      include_dirs = []
+      defines = []
+      cflags_c = []
+      ldflags = []
+    }
+    ```
+
+3.  添加新组件
+
+    修改文件**build/lite/components/applications.json**，添加组件hello\_world\_app的配置，如下所示为applications.json文件片段，"\#\#start\#\#"和"\#\#end\#\#"之间为新增配置（"\#\#start\#\#"和"\#\#end\#\#"仅用来标识位置，添加完配置后删除这两行）：
+
+    ```
+    {
+      "components": [
+        {
+          "component": "camera_sample_communication",
+          "description": "Communication related samples.",
+          "optional": "true",
+          "dirs": [
+            "applications/sample/camera/communication"
+          ],
+          "targets": [
+            "//applications/sample/camera/communication:sample"
+          ],
+          "rom": "",

+
+## 源码编译<a name="section191121332125319"></a>
+
+本节描述如何在Linux服务器上进行WLAN模组版本的编译。
+
+如果Linux编译环境通过Docker方式安装，具体编译过程请参见[Docker方式获取编译环境](../get-code/sourcecode-acquire.md)的编译操作。如果Linux编译环境通过软件包方式安装，请参考如下步骤。
+
+1.  打开DevEco Device Tool工具，点击“View \> Terminal”，进入终端界面。
+
+    **图 1**  IDE终端工具打开方法<a name="fig1975813338510"></a>

+
+    **图 8**  WLAN复位成功示意图<a name="fig496084516332"></a>  
+    
+
+    ![](figure/6.png)
+
+3.  在DevEco的串口终端中，依次执行如下AT命令，启动STA模式，连接指定AP热点，并开启DHCP功能。
+
+    ```
+    AT+STARTSTA                             # 启动STA模式
+    AT+SCAN                                 # 扫描周边AP
+    AT+SCANRESULT                           # 显示扫描结果
+    AT+CONN="SSID",,2,"PASSWORD"            # 连接指定AP，其中SSID/PASSWORD为待连接的热点名称和密码
+    AT+STASTAT                              # 查看连接结果
+    AT+DHCP=wlan0,1                         # 通过DHCP向AP请求wlan0的IP地址
+    ```
+
+4.  查看WLAN模组与网关联通是否正常，如下图所示。
+
+    ```
+    AT+IFCFG                                # 查看模组接口IP
+    AT+PING=X.X.X.X                         # 检查模组与网关的联通性，其中X.X.X.X需替换为实际的网关地址
+    ```

+
+本示例将演示如何编写简单业务，输出“Hello World”，初步了解OpenHarmony 如何运行在开发板上。
+
+## 修改源码<a name="section79601457101015"></a>
+
+bugfix和新增业务两种情况，涉及源码修改。下面以新增业务（my\_first\_app）为例，向开发者介绍如何进行源码修改。
+
+1.  <a name="li5479332115116"></a>确定目录结构。
+
+    开发者编写业务时，务必先在./applications/sample/wifi-iot/app路径下新建一个目录（或一套目录结构），用于存放业务源码文件。
+
+    例如：在app下新增业务my\_first\_app，其中hello\_world.c为业务代码，BUILD.gn为编译脚本，具体规划目录结构如下：
+
+    ```
+    .
+    └── applications
+        └── sample
+            └── wifi-iot
+                └── app
+                    │── my_first_app
+                    │  │── hello_world.c
+                    │  └── BUILD.gn
+                    └── BUILD.gn
+    ```
+
+2.  编写业务代码。
+
+    新建./applications/sample/wifi-iot/app/my\_first\_app下的hello\_world.c文件，在hello\_world.c中新建业务入口函数HelloWorld，并实现业务逻辑。并在代码最下方，使用OpenHarmony启动恢复模块接口SYS\_RUN\(\)启动业务。（SYS\_RUN定义在ohos\_init.h文件中）
+
+    ```
+    #include <stdio.h>
+    #include "ohos_init.h"
+    #include "ohos_types.h"
+    
+    void HelloWorld(void)
+    {
+        printf("[DEMO] Hello world.\n");
+    }
+    SYS_RUN(HelloWorld);
+    ```
+
+3.  编写用于将业务构建成静态库的BUILD.gn文件。
+
+    新建./applications/sample/wifi-iot/app/my\_first\_app下的BUILD.gn文件，并完成如下配置。
+
+    如[步骤1](#li5479332115116)所述，BUILD.gn文件由三部分内容（目标、源文件、头文件路径）构成，需由开发者完成填写。
+
+    ```
+    static_library("myapp") {
+        sources = [
+            "hello_world.c"
+        ]
+        include_dirs = [
+            "//utils/native/lite/include"
+        ]
+    }
+    ```
+
+    -   static\_library中指定业务模块的编译结果，为静态库文件libmyapp.a，开发者根据实际情况完成填写。
+    -   sources中指定静态库.a所依赖的.c文件及其路径，若路径中包含"//"则表示绝对路径（此处为代码根路径），若不包含"//"则表示相对路径。
+    -   include\_dirs中指定source所需要依赖的.h文件路径。
+
+4.  编写模块BUILD.gn文件，指定需参与构建的特性模块。
+
+    配置./applications/sample/wifi-iot/app/BUILD.gn文件，在features字段中增加索引，使目标模块参与编译。features字段指定业务模块的路径和目标，以my\_first\_app举例，features字段配置如下。
+
+    ```
+    import("//build/lite/config/component/lite_component.gni")
+

+## 调测验证<a name="section1621064881419"></a>
+
+目前调试验证的方法有两种，分别为通过printf打印日志、通过asm文件定位panic问题，开发者可以根据具体业务情况选择。
+
+由于本示例业务简单，采用printf打印日志的调试方式即可。下面开始介绍这两种调试手段的使用方法。
+
+## printf打印<a name="section1246911301217"></a>
+
+代码中增加printf维测，信息会直接打印到串口上。开发者可在业务关键路径或业务异常位置增加日志打印，如下所示。
+
+```
+void HelloWorld(void)
+{
+    printf("[DEMO] Hello world.\n");
+}
+```
+
+## 根据asm文件进行问题定位<a name="section199621957141014"></a>
+
+系统异常退出时，会在串口上打印异常退出原因调用栈信息，如下文所示。通过解析异常栈信息可以定位异常位置。
+
+```
+=======KERNEL PANIC=======
+**********************Call Stack*********************
+Call Stack 0 -- 4860d8 addr:f784c
+Call Stack 1 -- 47b2b2 addr:f788c
+Call Stack 2 -- 3e562c addr:f789c
+Call Stack 3 -- 4101de addr:f78ac
+Call Stack 4 -- 3e5f32 addr:f78cc
+Call Stack 5 -- 3f78c0 addr:f78ec
+Call Stack 6 -- 3f5e24 addr:f78fc
+********************Call Stack end*******************
+```
+
+为解析上述调用栈信息，需要使用到Hi3861\_wifiiot\_app.asm文件，该文件记录了代码中函数在Flash上的符号地址以及反汇编信息。asm文件会随版本大包一同构建输出，存放在./out/wifiiot/路径下。
+
+1.  将调用栈CallStack信息保存到txt文档中，以便于编辑。（可选）
+2.  打开asm文件，并搜索CallStack中的地址，列出对应的函数名 信息。通常只需找出前几个栈信息对应的函数，就可明确异常代码方向。
+
+    ```
+    Call Stack 0 -- 4860d8 addr:f784c -- WadRecvCB
+    Call Stack 1 -- 47b2b2 addr:f788c -- wal_sdp_process_rx_data
+    Call Stack 2 -- 3e562c addr:f789c
+    Call Stack 3 -- 4101de addr:f78ac
+    Call Stack 4 -- 3e5f32 addr:f78cc
+    Call Stack 5 -- 3f78c0 addr:f78ec
+    Call Stack 6 -- 3f5e24 addr:f78fc
+    ```
+
+3.  根据以上调用栈信息，可以定位WadRecvCB函数中出现了异常。
+
+    ![](figure/zh-cn_image_0000001174270737.png)
+
+4.  完成代码排查及修改。
+
+## 运行结果<a name="section18115713118"></a>
+
+示例代码编译、烧录、运行、调测后，在串口界面会显示如下结果：
+
+```
+ready to OS start
+FileSystem mount ok.
+wifi init success!
+[DEMO] Hello world.
+```

+OpenHarmony标准系统为开发者提供的Docker环境已经将对应的编译工具链进行了封装，开发者可省略对应工具的安装。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>-   在使用Docker前需要先安装Docker，Docker安装请参考[官方指导](https://docs.docker.com/engine/install/ubuntu/)。
+>-   Docker方式和安装包方式二选一即可。选择Docker方式的开发者可跳过[安装包方式](quickstart-standard-package-environment.md)的内容。

+## 获取标准系统源码<a name="section8761819202511"></a>
+
+### 前提条件<a name="section102871547153314"></a>
+
+1.  注册码云gitee账号。
+2.  注册码云SSH公钥，请参考[码云帮助中心](https://gitee.com/help/articles/4191)。
+3.  安装[git客户端](http://git-scm.com/book/zh/v2/%E8%B5%B7%E6%AD%A5-%E5%AE%89%E8%A3%85-Git)和[git-lfs](https://gitee.com/vcs-all-in-one/git-lfs?_from=gitee_search#downloading))并配置用户信息。
+
+    ```
+    git config --global user.name "yourname"
+    git config --global user.email "your-email-address"
+    git config --global credential.helper store
+    ```
+
+4.  安装码云repo工具，可以执行如下命令。
+
+    ```
+    curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo  #如果没有权限，可下载至其他目录，并将其配置到环境变量中
+    chmod a+x /usr/local/bin/repo
+    pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests
+    ```
+
+
+### 操作步骤<a name="section429012478331"></a>
+
+方式一（推荐）：通过repo + ssh 下载（需注册公钥，请参考[码云帮助中心](https://gitee.com/help/articles/4191)）。
+
+```
+repo init -u git@gitee.com:openharmony/manifest.git -b master --no-repo-verify
+repo sync -c
+repo forall -c 'git lfs pull'
+```
+
+方式二：通过repo + https 下载。
+
+```
+repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify
+repo sync -c
+repo forall -c 'git lfs pull'
+```
+
+## 获取Docker环境<a name="section181431248132513"></a>
+
+**方式一：从HuaweiCloud SWR上直接获取Docker镜像进行构建：**
+
+1.  获取Docker镜像。
+
+    ```
+    docker pull swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.1
+    ```
+
+2.  进入OpenHarmony代码根目录执行如下命令，从而进入Docker构建环境。
+
+    ```
+    docker run -it -v $(pwd):/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.1
+    ```
+
+
+**方式二：通过Dockerfile 构建本地Docker镜像进行构建**
+
+1.  获取Dockerfile脚本文件，用来构建本地Docker镜像。
+
+    ```
+    git clone https://gitee.com/openharmony/docs.git
+    ```
+
+2.  进入Dockerfile代码目录路径执行Docker镜像构建命令。
+
+    ```
+    cd docs/docker/standard
+    ./build.sh
+    ```
+
+3.  进入OpenHarmony代码根目录执行如下命令，从而进入Docker构建环境。
+
+    ```
+    docker run -it -v $(pwd):/home/openharmony openharmony-docker-standard:0.0.1
+    ```
+
+
+## 编译<a name="section92391739152318"></a>
+
+1.  在源码的根目录执行预处理脚本。
+
+    ```
+    ../scripts/prepare.sh
+    ```
+
+2.  通过如下编译脚本启动标准系统类设备（参考内存≥128MB）的编译。
+
+    ```
+    ./build.sh --product-name {product_name}
+    ```
+
+    \{product\_name\}为当前版本支持的平台，比如：Hi3516DV300
+
+    编译所生成的文件都归档在out/ohos-arm-release/目录下，结果镜像输出在 out/ohos-arm-release/packages/phone/images/ 目录下。
+
+3.  编译源码完成，请进行镜像烧录，具体请参见[镜像烧录](quickstart-standard-burn.md)。
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>退出Docker执行exit命令即可。

-本节指导开发者在单板上运行第一个应用程序，其中包括新建应用程序、编译、烧写、运行等步骤，最终输出“Hello OHOS！”。
-
-## 新建应用程序<a name="section1550972416485"></a>
-
-1.  新建目录及源码
-
-    新建**applications/sample/camera/apps/src/helloworld.c**目录及文件，代码如下所示，用户可以自定义修改打印内容（例如：修改OHOS为World）。当前应用程序可支持标准C及C++的代码开发。
-
-    ```
-    #include <stdio.h>
-    
-    int main(int argc, char **argv)
-    {
-        printf("\n************************************************\n");
-        printf("\n\t\tHello OHOS!\n");
-        printf("\n************************************************\n\n");
-    
-        return 0;
-    }
-    ```
-
-2.  新建编译组织文件
-
-    新建**applications/sample/camera/apps/BUILD.gn**文件，内容如下所示：
-
-    ```
-    import("//build/lite/config/component/lite_component.gni")
-    lite_component("hello-OHOS") {
-      features = [ ":helloworld" ]
-    }
-    executable("helloworld") {
-      output_name = "helloworld"
-      sources = [ "src/helloworld.c" ]
-      include_dirs = []
-      defines = []
-      cflags_c = []
-      ldflags = []
-    }
-    ```
-
-3.  添加新组件
-
-    修改文件**build/lite/components/applications.json**，添加组件hello\_world\_app的配置，如下所示为applications.json文件片段，"\#\#start\#\#"和"\#\#end\#\#"之间为新增配置（"\#\#start\#\#"和"\#\#end\#\#"仅用来标识位置，添加完配置后删除这两行）：
-
-    ```

-            "third_party": []
-          }
-        },
-    ##end##
-        {
-          "component": "camera_sample_app",
-          "description": "Camera related samples.",
-          "optional": "true",
-          "dirs": [
-            "applications/sample/camera/launcher",
-            "applications/sample/camera/cameraApp",
-            "applications/sample/camera/setting",
-            "applications/sample/camera/gallery",
-            "applications/sample/camera/media"
-          ],
-    ```
-
-4.  修改单板配置文件
-
-    修改文件**vendor/hisilicon/hispark\_aries/config.json**，新增hello\_world\_app组件的条目，如下所示代码片段为applications子系统配置，"\#\#start\#\#"和"\#\#end\#\#"之间为新增条目（"\#\#start\#\#"和"\#\#end\#\#"仅用来标识位置，添加完配置后删除这两行）：
-
-    ```
-          {
-            "subsystem": "applications",
-            "components": [
-    ##start##
-              { "component": "hello_world_app", "features":[] },
-    ##end##
-              { "component": "camera_sample_app", "features":[] }
-    
-            ]
-          },
-    ```
-
-
-## 编译<a name="section234175193114"></a>
-
-如果Linux编译环境通过Docker方式安装，具体编译过程请参见[Docker方式获取编译环境](../get-code/Docker编译环境.md)的编译操作。如果Linux编译环境通过软件包方式安装，进入源码根目录，执行如下命令进行编译：
-
-```
-hb set(设置编译路径)
-.（选择当前路径）
-选择ipcamera_hispark_aries@hisilicon并回车
-hb build -f（执行编译）
-```
-
-结果文件生成在out/hispark\_aries/ipcamera\_hispark\_aries目录下。

-
-本示例将演示如何编写简单业务，输出“Hello World”，初步了解OpenHarmony 如何运行在开发板上。
-
-## 修改源码<a name="section79601457101015"></a>
-
-bugfix和新增业务两种情况，涉及源码修改。下面以新增业务（my\_first\_app）为例，向开发者介绍如何进行源码修改。
-
-1.  <a name="li5479332115116"></a>确定目录结构。
-
-    开发者编写业务时，务必先在./applications/sample/wifi-iot/app路径下新建一个目录（或一套目录结构），用于存放业务源码文件。
-
-    例如：在app下新增业务my\_first\_app，其中hello\_world.c为业务代码，BUILD.gn为编译脚本，具体规划目录结构如下：
-
-    ```
-    .
-    └── applications
-        └── sample
-            └── wifi-iot
-                └── app
-                    │── my_first_app
-                    │  │── hello_world.c
-                    │  └── BUILD.gn
-                    └── BUILD.gn
-    ```
-
-2.  编写业务代码。
-
-    新建./applications/sample/wifi-iot/app/my\_first\_app下的hello\_world.c文件，在hello\_world.c中新建业务入口函数HelloWorld，并实现业务逻辑。并在代码最下方，使用OpenHarmony启动恢复模块接口SYS\_RUN\(\)启动业务。（SYS\_RUN定义在ohos\_init.h文件中）
-
-    ```
-    #include <stdio.h>
-    #include "ohos_init.h"
-    #include "ohos_types.h"
-    
-    void HelloWorld(void)
-    {
-        printf("[DEMO] Hello world.\n");
-    }
-    SYS_RUN(HelloWorld);
-    ```
-
-3.  编写用于将业务构建成静态库的BUILD.gn文件。
-
-    新建./applications/sample/wifi-iot/app/my\_first\_app下的BUILD.gn文件，并完成如下配置。
-
-    如[步骤1](#li5479332115116)所述，BUILD.gn文件由三部分内容（目标、源文件、头文件路径）构成，需由开发者完成填写。
-
-    ```
-    static_library("myapp") {
-        sources = [
-            "hello_world.c"
-        ]
-        include_dirs = [
-            "//utils/native/lite/include"
-        ]
-    }
-    ```
-
-    -   static\_library中指定业务模块的编译结果，为静态库文件libmyapp.a，开发者根据实际情况完成填写。
-    -   sources中指定静态库.a所依赖的.c文件及其路径，若路径中包含"//"则表示绝对路径（此处为代码根路径），若不包含"//"则表示相对路径。
-    -   include\_dirs中指定source所需要依赖的.h文件路径。
-
-4.  编写模块BUILD.gn文件，指定需参与构建的特性模块。
-
-    配置./applications/sample/wifi-iot/app/BUILD.gn文件，在features字段中增加索引，使目标模块参与编译。features字段指定业务模块的路径和目标，以my\_first\_app举例，features字段配置如下。
-
-    ```
-    import("//build/lite/config/component/lite_component.gni")
-    
-    lite_component("app") {
-        features = [
-            "my_first_app:myapp",
-        ]
-    }
-    ```
-
-    -   my\_first\_app是相对路径，指向./applications/sample/wifi-iot/app/my\_first\_app/BUILD.gn。
-    -   myapp是目标，指向./applications/sample/wifi-iot/app/my\_first\_app/BUILD.gn中的static\_library\("myapp"\)。
-
-
-## 调测验证<a name="section1621064881419"></a>
-
-目前调试验证的方法有两种，分别为通过printf打印日志、通过asm文件定位panic问题，开发者可以根据具体业务情况选择。
-
-由于本示例业务简单，采用printf打印日志的调试方式即可。下面开始介绍这两种调试手段的使用方法。
-
-## printf打印<a name="section1246911301217"></a>
-
-代码中增加printf维测，信息会直接打印到串口上。开发者可在业务关键路径或业务异常位置增加日志打印，如下所示。
-
-```
-void HelloWorld(void)
-{
-    printf("[DEMO] Hello world.\n");
-}
-```
-
-## 根据asm文件进行问题定位<a name="section199621957141014"></a>
-
-系统异常退出时，会在串口上打印异常退出原因调用栈信息，如下文所示。通过解析异常栈信息可以定位异常位置。
-
-```
-=======KERNEL PANIC=======
-**********************Call Stack*********************
-Call Stack 0 -- 4860d8 addr:f784c
-Call Stack 1 -- 47b2b2 addr:f788c
-Call Stack 2 -- 3e562c addr:f789c
-Call Stack 3 -- 4101de addr:f78ac
-Call Stack 4 -- 3e5f32 addr:f78cc
-Call Stack 5 -- 3f78c0 addr:f78ec
-Call Stack 6 -- 3f5e24 addr:f78fc
-********************Call Stack end*******************
-```
-
-为解析上述调用栈信息，需要使用到Hi3861\_wifiiot\_app.asm文件，该文件记录了代码中函数在Flash上的符号地址以及反汇编信息。asm文件会随版本大包一同构建输出，存放在./out/wifiiot/路径下。
-
-1.  将调用栈CallStack信息保存到txt文档中，以便于编辑。（可选）
-2.  打开asm文件，并搜索CallStack中的地址，列出对应的函数名 信息。通常只需找出前几个栈信息对应的函数，就可明确异常代码方向。
-
-    ```
-    Call Stack 0 -- 4860d8 addr:f784c -- WadRecvCB
-    Call Stack 1 -- 47b2b2 addr:f788c -- wal_sdp_process_rx_data
-    Call Stack 2 -- 3e562c addr:f789c
-    Call Stack 3 -- 4101de addr:f78ac
-    Call Stack 4 -- 3e5f32 addr:f78cc
-    Call Stack 5 -- 3f78c0 addr:f78ec
-    Call Stack 6 -- 3f5e24 addr:f78fc
-    ```
-
-3.  根据以上调用栈信息，可以定位WadRecvCB函数中出现了异常。
-
-    ![](figures/zh-cn_image_0000001174270737.png)
-
-4.  完成代码排查及修改。
-
-## 运行结果<a name="section18115713118"></a>

-
-## 驱动程序介绍<a name="s8efc1952ebfe4d1ea717182e108c29bb"></a>
-
-下面基于HDF框架，提供一个简单的UART（Universal Asynchronous Receiver/Transmitter）平台驱动开发样例，包含配置文件的添加，驱动代码的实现以及用户态程序和驱动交互的流程。驱动程序源码位于vendor/huawei/hdf/sample目录
-
-1.  添加配置。
-
-    在HDF框架的驱动配置文件（例如device/hisilicon/hi3516dv300/sdk\_liteos/config/uart/uart\_config.hcs）中添加该驱动的配置信息，如下所示：
-
-    ```
-    root {
-        platform {
-            uart_sample {
-                num = 5;            // UART设备编号
-                base = 0x120a0000;  // UART 寄存器基地址
-                irqNum = 38;
-                baudrate = 115200;
-                uartClk = 24000000;
-                wlen = 0x60;
-                parity = 0;
-                stopBit = 0;
-                match_attr = "sample_uart_5";
-            }
-        }
-    }
-    ```
-
-    在HDF框架的设备配置文件（例如vendor/hisilicon/ipcamera\_hi3516dv300\_liteos/config/device\_info/device\_info.hcs）中添加该驱动的设备节点信息，如下所示：
-
-    ```
-    root {
-        device_info {
-            platform :: host {
-                hostName = "platform_host";
-                priority = 50;
-                device_uart :: device {
-                    device5 :: deviceNode {
-                        policy = 2;
-                        priority = 10;
-                        permission = 0660;
-                        moduleName = "UART_SAMPLE";
-                        serviceName = "HDF_PLATFORM_UART_5";
-                        deviceMatchAttr = "sample_uart_5";
-                    }
-                }
-            }
-        }
-    }
-    ```
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >配置文件与UART驱动示例的源码在同一个路径，需要手动添加到Hi3516DV300单板路径下。
-
-2.  注册UART驱动入口。
-
-    基于HDF框架注册UART驱动的入口HdfDriverEntry，代码如下：
-
-    ```
-    // 绑定UART驱动接口到HDF框架
-    static int32_t SampleUartDriverBind(struct HdfDeviceObject *device)
-    {
-        struct UartHost *uartHost = NULL;
-    
-        if (device == NULL) {
-            return HDF_ERR_INVALID_OBJECT;
-        }
-        HDF_LOGI("Enter %s:", __func__);
-    
-        uartHost = UartHostCreate(device);
-        if (uartHost == NULL) {
-            HDF_LOGE("%s: UartHostCreate failed", __func__);
-            return HDF_FAILURE;
-        }
-        uartHost->service.Dispatch = SampleDispatch;
-        return HDF_SUCCESS;
-    }
-     
-    // 从UART驱动的HCS中获取配置信息
-    static uint32_t GetUartDeviceResource(
-        struct UartDevice *device, const struct DeviceResourceNode *resourceNode)
-    {
-        struct UartResource *resource = &device->resource;
-        struct DeviceResourceIface *dri = NULL;
-        dri = DeviceResourceGetIfaceInstance(HDF_CONFIG_SOURCE);
-        if (dri == NULL || dri->GetUint32 == NULL) {
-            HDF_LOGE("DeviceResourceIface is invalid");
-            return HDF_FAILURE;
-        }
-    
-        if (dri->GetUint32(resourceNode, "num", &resource->num, 0) != HDF_SUCCESS) {
-            HDF_LOGE("uart config read num fail");
-            return HDF_FAILURE;
-        }
-        if (dri->GetUint32(resourceNode, "base", &resource->base, 0) != HDF_SUCCESS) {

-            return HDF_FAILURE;
-        }
-        resource->physBase = (unsigned long)OsalIoRemap(resource->base, 0x48);
-        if (resource->physBase == 0) {
-            HDF_LOGE("uart config fail to remap physBase");
-            return HDF_FAILURE;
-        }
-        if (dri->GetUint32(resourceNode, "irqNum", &resource->irqNum, 0) != HDF_SUCCESS) {
-            HDF_LOGE("uart config read irqNum fail");
-            return HDF_FAILURE;
-        }
-        if (dri->GetUint32(resourceNode, "baudrate", &resource->baudrate, 0) != HDF_SUCCESS) {
-            HDF_LOGE("uart config read baudrate fail");
-            return HDF_FAILURE;
-        }
-        if (dri->GetUint32(resourceNode, "wlen", &resource->wlen, 0) != HDF_SUCCESS) {
-            HDF_LOGE("uart config read wlen fail");
-            return HDF_FAILURE;
-        }
-        if (dri->GetUint32(resourceNode, "parity", &resource->parity, 0) != HDF_SUCCESS) {
-            HDF_LOGE("uart config read parity fail");
-            return HDF_FAILURE;
-        }
-        if (dri->GetUint32(resourceNode, "stopBit", &resource->stopBit, 0) != HDF_SUCCESS) {
-            HDF_LOGE("uart config read stopBit fail");
-            return HDF_FAILURE;
-        }
-        if (dri->GetUint32(resourceNode, "uartClk", &resource->uartClk, 0) != HDF_SUCCESS) {
-            HDF_LOGE("uart config read uartClk fail");
-            return HDF_FAILURE;
-        }
-        return HDF_SUCCESS;
-    }
-     
-    // 将UART驱动的配置和接口附加到HDF驱动框架
-    static int32_t AttachUartDevice(struct UartHost *host, struct HdfDeviceObject *device)
-    {
-        int32_t ret;
-        struct UartDevice *uartDevice = NULL;
-        if (device->property == NULL) {
-            HDF_LOGE("%s: property is NULL", __func__);
-            return HDF_FAILURE;
-        }
-        uartDevice = (struct UartDevice *)OsalMemCalloc(sizeof(struct UartDevice));
-        if (uartDevice == NULL) {
-            HDF_LOGE("%s: OsalMemCalloc uartDevice error", __func__);
-            return HDF_ERR_MALLOC_FAIL;
-        }
-        ret = GetUartDeviceResource(uartDevice, device->property);
-        if (ret != HDF_SUCCESS) {
-            (void)OsalMemFree(uartDevice);
-            return HDF_FAILURE;
-        }
-        host->num = uartDevice->resource.num;
-        host->priv = uartDevice;
-        AddUartDevice(host);
-        return InitUartDevice(uartDevice);
-    }
-     
-    // 初始化UART驱动
-    static int32_t SampleUartDriverInit(struct HdfDeviceObject *device)
-    {

-        host->method = &g_sampleUartHostMethod;
-        return ret;
-    }
-     
-    static void DeinitUartDevice(struct UartDevice *device)
-    {

-    static void DetachUartDevice(struct UartHost *host)
-    {
-        struct UartDevice *uartDevice = NULL;
-

-    };
-     
-    HDF_INIT(g_sampleUartDriverEntry);
-    ```
-
-3.  注册UART驱动接口。
-
-    HDF框架提供了UART驱动接口的模板方法UartHostMethod，实现UART驱动接口的代码如下：
-
-    ```
-    static int32_t SampleUartHostInit(struct UartHost *host)
-    {
-        HDF_LOGI("%s: Enter", __func__);
-        if (host == NULL) {
-            HDF_LOGE("%s: invalid parameter", __func__);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        return HDF_SUCCESS;
-    }
-    
-    static int32_t SampleUartHostDeinit(struct UartHost *host)
-    {
-        HDF_LOGI("%s: Enter", __func__);
-        if (host == NULL) {
-            HDF_LOGE("%s: invalid parameter", __func__);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        return HDF_SUCCESS;
-    }
-    
-    // 向UART中写入数据
-    static int32_t SampleUartHostWrite(struct UartHost *host, uint8_t *data, uint32_t size)
-    {
-        HDF_LOGI("%s: Enter", __func__);
-        uint32_t idx;
-        struct UartRegisterMap *regMap = NULL;
-        struct UartDevice *device = NULL;
-    
-        if (host == NULL || data == NULL || size == 0) {
-            HDF_LOGE("%s: invalid parameter", __func__);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        device = (struct UartDevice *)host->priv;
-        if (device == NULL) {
-            HDF_LOGE("%s: device is NULL", __func__);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        regMap = (struct UartRegisterMap *)device->resource.physBase;
-        for (idx = 0; idx < size; idx++) {
-            UartPl011Write(regMap, data[idx]);
-        }
-        return HDF_SUCCESS;
-    }
-     
-    // 设置UART的波特率
-    static int32_t SampleUartHostSetBaud(struct UartHost *host, uint32_t baudRate)
-    {
-        HDF_LOGI("%s: Enter", __func__);
-        struct UartDevice *device = NULL;
-        struct UartRegisterMap *regMap = NULL;
-        UartPl011Error err;
-    
-        if (host == NULL) {
-            HDF_LOGE("%s: invalid parameter", __func__);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        device = (struct UartDevice *)host->priv;
-        if (device == NULL) {
-            HDF_LOGE("%s: device is NULL", __func__);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        regMap = (struct UartRegisterMap *)device->resource.physBase;
-        if (device->state != UART_DEVICE_INITIALIZED) {
-            return UART_PL011_ERR_NOT_INIT;
-        }
-        if (baudRate == 0) {
-            return UART_PL011_ERR_INVALID_BAUD;
-        }
-        err = UartPl011SetBaudrate(regMap, device->uartClk, baudRate);
-        if (err == UART_PL011_ERR_NONE) {
-            device->baudrate = baudRate;
-        }
-        return err;
-    }
-     
-    // 获取UART的波特率
-    static int32_t SampleUartHostGetBaud(struct UartHost *host, uint32_t *baudRate)
-    {
-        HDF_LOGI("%s: Enter", __func__);
-        struct UartDevice *device = NULL;
-    
-        if (host == NULL) {
-            HDF_LOGE("%s: invalid parameter", __func__);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        device = (struct UartDevice *)host->priv;
-        if (device == NULL) {
-            HDF_LOGE("%s: device is NULL", __func__);
-            return HDF_ERR_INVALID_PARAM;
-        }
-        *baudRate = device->baudrate;
-        return HDF_SUCCESS;
-    }
-     
-    // 在HdfUartSampleInit方法中绑定
-    struct UartHostMethod g_sampleUartHostMethod = {
-        .Init = SampleUartHostInit,
-        .Deinit = SampleUartHostDeinit,
-        .Read = NULL,
-        .Write = SampleUartHostWrite,
-        .SetBaud = SampleUartHostSetBaud,
-        .GetBaud = SampleUartHostGetBaud,
-        .SetAttribute = NULL,
-        .GetAttribute = NULL,
-        .SetTransMode = NULL,
-    };
-    ```
-
-    在device/hisilicon/drivers/lite.mk编译脚本中增加示例UART驱动模块，代码如下：
-
-    ```
-    LITEOS_BASELIB += -lhdf_uart_sample
-    LIB_SUBDIRS    += $(LITEOS_SOURCE_ROOT)/vendor/huawei/hdf/sample/platform/uart
-    ```
-
-4.  用户程序和驱动交互代码。
-
-    UART驱动成功初始化后，会创建/dev/uartdev-5设备节点，通过设备节点与UART驱动交互的代码如下：
-
-    ```
-    #include <stdlib.h>
-    #include <unistd.h>
-    #include <fcntl.h>
-    #include "hdf_log.h"
-    
-    #define HDF_LOG_TAG "hello_uart"
-    #define INFO_SIZE 16
-    
-    int main(void)
-    {
-        int ret;
-        int fd;
-        const char info[INFO_SIZE] = {" HELLO UART! "};
-    
-        fd = open("/dev/uartdev-5", O_RDWR);
-        if (fd < 0) {
-            HDF_LOGE("hello_uart uartdev-5 open failed %d", fd);
-            return -1;
-        }
-        ret = write(fd, info, INFO_SIZE);
-        if (ret != 0) {
-            HDF_LOGE("hello_uart write uartdev-5 ret is %d", ret);
-        }
-        ret = close(fd);
-        if (ret != 0) {
-            HDF_LOGE("hello_uart uartdev-5 close failed %d", fd);
-            return -1;
-        }
-        return ret;
-    }
-    ```
-
-    在build/lite/components/drivers.json驱动配置中hdf\_hi3516dv300\_liteos\_a组件下的targets中增加hello\_uart\_sample组件，代码如下：
-
-    ```
-    {
-      "components": [
-        {
-          "component": "hdf_hi3516dv300_liteos_a",
-          ...
-          "targets": [
-            "//vendor/huawei/hdf/sample/platform/uart:hello_uart_sample"
-          ]
-        }
-      ]
-    }
-    ```

+## 隐私保护概述<a name="section13200134331414"></a>
+
+随着互联网及信息化的发展，个人数据在社会经济和日常生活中发挥着越来越重要的作用。与此同时，个人数据泄露的风险也在增加，消费者产品开发者需要更加有效的保护用户的个人数据，提高用户对产品的信任度。为了提升消费者的隐私体验，产品应默认设置较高级别隐私保护策略，达到保护消费者隐私的目的。
+
+**基本概念**
+
+-   **个人数据（Personal Data）**
+
+    与一个身份已被识别或者身份可被识别的自然人（“数据主体”）相关的任何信息；身份可识别的自然人是指其身份可以通过诸如姓名、身份证号、位置数据等识别码或者通过一个或多个与自然人的身体、生理、精神、经济、文化或者社会身份相关的特定因素来直接或者间接地被识别。个人数据包括：自然人的email地址、电话号码、生物特征（指纹）、位置数据、IP地址、医疗信息、宗教信仰、社保号、婚姻状态等。
+
+-   **敏感个人数据（Sensitive Personal Data）**
+
+    敏感个人数据是个人数据的一个重要子集，指的是涉及数据主体的最私密领域的信息或者一旦泄露可能会给数据主体造成重大不利影响的数据。欧盟等国家和地区法律定义的敏感个人数据包括种族、政治观点、宗教和哲学信仰、工会成员资格、基因数据、生物信息、健康和性生活状况、性取向等。
+
+    根据业界最佳实践，敏感个人数据还包括可与自然人身份相关联的银行卡号、身份证号、护照号、口令等。敏感个人数据的处理需要更多更严格的保护措施。
+
+-   **公开个人数据（Public available Personal Data）**
+
+    数据主体主动公开的个人数据，或公开网页/应用上可访问的个人数据，包括论坛公开的发帖、评论等。
+
+-   **用户画像（User Profile）**
+
+    指对个人数据采取的任何自动化处理的方式，包括评估某个自然人特定方面的情况，尤其是为了分析和预测该自然人的工作表现、经济状况、健康、个人喜好、兴趣、可信度、行为举止、所在位置或行迹。
+
+-   **数据控制者（Data Controller）**
+
+    单独或者与他人共同确定个人数据处理的目的和手段的自然人、法人、公共机构、政府部门或其他机构。
+
+-   **数据处理者（Data Processor）**
+
+    指代表数据控制者处理个人数据的自然人、法人、公共机构、政府部门或其他机构。数据处理者必须按照数据控制者的要求对个人数据进行充分的保护。
+
+-   **明示同意（Explicit consent）**
+
+    如下几种情形GDPR法律提到可以通过数据主体明示同意的方式合法地处理数据：
+
+    -   处理敏感个人数据。
+    -   自动化决策，包括进行用户画像。
+    -   向不具备充分保护水平的国家转移个人数据，并以同意作为合法性基础。
+
+    实现明示同意的方式有：
+
+    -   在收集特定数据时，弹出隐私声明告知个人数据处理相关事项，提供勾选框但不默认勾选，让数据主体勾选“我同意以上述方式处理我的个人数据”，或提供“我同意”的按钮让用户主动点击。
+    -   以书面的方式明确表达同意，数据主体在书面陈述上签字。
+    -   要求数据主体在系统中上传带有其签名的电子表格。
+    -   采取双重验证的方式，要求数据主体邮件形式回复同意后，再次点击用于验证的邮件链接或是输入SMS验证码。
+    -   用户主动输入的场景，例如用户主动输入身份证和银行卡号绑卡等场景。
+
+
+## 数据分类分级<a name="section2371104991511"></a>
+
+基于数据保护目标及风险后果，即数据遭到泄露或者遭到破坏带来的法律风险对个人、组织或公众的影响对数据进行定级，分为极高、高、中、低、公开五个数据级别。
+
+**表1**  数据分类分级标准

+
+## 通用隐私设计规则<a name="section10354102411162"></a>
+
+为了指导厂商完成产品的隐私设计工作，我们整理了以下通用的隐私设计要求，作为OpenHarmony设备厂商产品隐私设计的指南和参考。
+
+**数据收集及使用公开透明**
+
+采集个人数据时，应清晰、明确地告知用户，并确保告知用户的个人信息将被如何使用。
+
+-   针对不同等级的个人数据需要制定针对性的隐私处理策略。
+    -   敏感个人数据的采集需要获取数据主体明示同意。
+    -   一般个人数据的采集需要数据主体同意或基于其他合法授权。
+    -   非个人数据与中、高或极高级别个人数据关联采集，需要数据主体同意或其他合法授权，并在隐私声明中呈现。
+
+-   应制定并遵从适当的隐私政策。在收集、使用留存和第三方分享用户个人数据时需要符合所有适用法律、政策和规定。如在收集个人数据前，需充分告知用户处理个人数据的种类、目的、处理方式、保留期限等，满足数据主体权利相关要求。
+
+    根据以上要求，我们设计了正确示例以供参考。隐私通知/声明的参考示例如下：
+
+    **图 1**  隐私通知/声明示例图<a name="fig1611815442274"></a>  
+    
+
+    ![](figure/2-应用启动预授权.png) ![](figure/3-应用隐私声明.png)
+
+-   个人数据应当基于具体、明确、合法的目的收集，不应与此目的不相符的方式作进一步处理。对于收集目的变更和用户撤销同意后再次重新使用的场景都需要用户重新同意。隐私声明变更和撤销的示例如下图：
+
+    **图 2**  隐私通知/声明变更示例图<a name="fig3591610523"></a>  
+    
+
+    ![](figure/4-隐私声明变更通知.png)
+
+    **图 3**  撤销同意示例图<a name="fig12802152515583"></a>  
+    
+
+    ![](figure/6-1-隐私声明撤销.png) ![](figure/6-2-隐私声明撤销.png)
+
+-   需要提供用户查看隐私声明的入口。例如，可以在应用的“关于”界面提供查看隐私声明的入口，如示例图所示：
+
+    **图 4**  隐私声明查看界面示例图<a name="fig11392538162011"></a>  
+    
+
+    ![](figure/5-应用隐私声明入口.png)
+
+
+**数据收集及使用最小化**
+
+个人数据收集应与数据处理目的相关，且是适当、必要的。开发者应尽可能对个人数据进行匿名化或假名化处理，降低对数据主体的风险。仅可收集和处理与特定目的相关且必需的个人数据，不能进行与特定目的不相关的进一步处理。
+
+-   敏感权限申请的时候要满足权限最小化的要求，在申请权限时，只申请获取必需的信息或资源所需要的权限。如应用不需要相机权限就能够实现其功能时，则不应该向用户申请相机权限。
+-   数据收集最小化：针对数据的收集要满足最小化要求，不收集与产品提供服务无关联的数据。如提供定位服务的产品，不应收集用户的网页浏览记录。
+-   数据使用的功能要求能够使用户受益，收集的数据不能用于一些与用户正常使用无关的功能。数据收集不能有其他与用户正常使用无关的功能存在。如不得将“生物特征”、“健康数据”等敏感个人数据用于服务改进、投放广告或营销等非业务核心功能。
+-   禁止在日志中打印敏感个人数据，如需要打印一般个人数据时，应对个人数据进行匿名化或假名化处理；
+
+    优先使用可以重置的标识符，如系统提供了NetworkID和DVID作为分布式场景下的设备标识符，广告业务场景下则建议使用[OAID](https://developer.huawei.com/consumer/cn/doc/development/HMSCore-Guides/oaid-0000001050783198)，基于应用的分析则建议使用[ODID](https://developer.huawei.com/consumer/cn/doc/development/HMSCore-Guides/odid-0000001051063255)和[AAID](https://developer.huawei.com/consumer/cn/doc/development/HMSCore-Guides/aaid-0000001051142988)，其他需要唯一标识符的场景可以使用UUID接口生成；可重置的标识符不能满足业务需求时，才选择序列号和MAC地址等永久性标识符。
+
+
+**数据处理选择和控制**
+
+对个人数据处理必须要征得用户的同意或遵守其他适用的法律法规，用户对其个人数据要有充分的控制权。
+
+-   获取用户敏感权限的授权：产品弹窗提醒，向用户呈现需要获取的权限和权限使用目的，用户可通过选择决定是否进行授权及指定授权的方式，让用户对产品权限的授予和个人数据使用做到透明、可知、可控。如下图所示：
+
+    **图 5**  敏感权限提示框示例图<a name="fig20776134521514"></a>  
+    
+
+    ![](figure/1-敏感权限弹窗.png)
+
+-   用户可以修改、取消授予的权限：当用户不同意某一权限或者数据收集时，应当允许用户使用与这部分权限和数据收集不相关的功能。如智慧屏产品上通信社交应用，用户可以拒绝授予相机权限，不应该影响与相机无关的功能操作，如语音通话。
+-   用户在产品使用过程中，针对录入个人数据的场景，需要给用户提供对个人数据的增加、删除、修改、查看的操作。
+-   需要给出硬件回收或返厂进行安全删除个人数据的机制或方法。
+-   对用户系统软件、应用软件的下载或升级，涉及修改用户隐私空间，用户对于这类行为需要有知情权和控制权，必须给用户提示，并提供给用户同意和取消的选项。
+
+**数据安全**
+
+从技术上保证数据处理活动的安全性，包括个人数据的加密存储、安全传输等安全机制，系统应默认开启或采取安全保护措施。
+
+-   对于个人数据的访问需要有保护机制，主要包括身份认证和访问控制。身份认证（如用户名、密码）限定只有经过认证的用户才能访问数据，可应用于多用户场景；访问控制（如[权限控制](safety-safeguide-security.md#li201725506375)）可应用于对应用程序的限制。
+-   分布式设备个人数据安全存储要满足密钥管理和存储服务（HUKS：Huawei Universal Keystore）的要求，包括：密钥安全存储、数据安全存储。
+-   个人数据在分布式设备间传输要满足设备间的信任绑定关系和数据传输通道的安全性要求。详细信息可以参考[设备互联安全](safety-safeguide-security.md#section26153183616)。
+-   认证凭证数据（密码、口令、指纹等）须加密存储。
+
+**本地化处理**
+
+用户数据优先在本设备进行处理，对于本设备无法处理的数据应尽可能在超级终端设备本地进行数据的处理，如果超级终端本地处理无法满足业务目的的，在数据离开超级终端设备本地时应尽可能选择匿名化。
+
+**未成年人数据保护要求**
+
+产品专门给未成年人设计的，或者产品收集用户年龄从而可以识别到是在收集未成年人的个人数据，需结合目标市场国家的法律，专门分析未成年人个人数据保护的问题，收集未成年人数据前需要征得监护人的同意。
+
+## 特殊品类要求<a name="section118861450201618"></a>
+
+针对消费者硬件产品来说，除了满足以上的通用隐私要求以外，针对特殊品类的产品还有以下的特殊要求，在产品设计过程中参照执行。

+## 安全概述<a name="section1521410017353"></a>
+
+OpenHarmony操作系统是一个开放的系统，开发者可以通过OpenHarmony开发灵活的服务和应用，为开发者和使用者带来便利和价值。为了达到这一目的，OpenHarmony提供了一个可以有效保护应用和用户数据的执行环境。
+
+在这个执行环境中，芯片的安全能力、系统的安全能力、以及上层的安全服务一起协作，从硬件安全、系统安全、数据安全、设备互联安全、应用安全、安全更新多个维度提供安全保障。

+
+### 安全机制<a name="section1399511541896"></a>
+
+-   启动可信根
+
+    OpenHarmony设备采用PKI（Public Key Infrastructure）体系保护软件完整性，确保设备运行来源合法、软件未被篡改。
+
+    在设备启动流程中，逐级进行软件签名校验形成安全启动链，任何一个环节的签名校验不通过即终止设备启动；安全启动链中最初执行签名校验的软硬件实体，需确保自身的合法、未被篡改。该实体即为设备的启动可信根。启动可信根可为固化在ROM中的一段代码，这段代码在芯片制造环节固化到芯片中，芯片制造完成后软件不可更改，在设备上电初始化的过程中，最先执行这段ROM中的代码，并由这段ROM代码执行后续的软件签名校验。
+
+    ROM中的代码在执行签名校验时，需确保用于校验的PKI公钥的合法性，OpenHarmony设备可采用eFuse/OTP等存储介质来存储公钥（如公钥哈希值），来保护公钥自身的合法性。公钥一般在设备制造环节，烧录到设备的eFuse/OTP中。
+
+-   硬件隔离可信环境
+
+    硬件隔离的可信环境，遵循了可信计算系统的设计理念。可信环境内外形成了两个世界：可信世界与不可信世界，两者之间存在清晰而明确的隔离边界；OpenHarmony设备在可信环境中实现了核心敏感数据的保护机制，可确保即使不可信世界的操作系统存在漏洞且被利用，也依然能确保可信环境中敏感数据的安全。
+
+    OpenHarmony设备的可信环境，基于硬件的安全隔离机制构建，在不同的OpenHarmony设备上芯片隔离机制略有差异，较为通用的方法是采用ARM的TrustZone技术。在部分Risc-V芯片平台上，也可能采用独立安全核的形式来构建可信环境。
+
+    可信环境中，运行特定的、精简的操作系统iTrustee lite，用于管理可信环境的资源和任务调度，给OpenHarmony设备提供安全服务。密钥管理及数据安全，是可信环境中最为常见的安全服务，设备在eFuse/OTP中存有硬件唯一根密钥，可信环境可基于该密钥结合业务上下文衍生出多种密钥，给应用提供密钥管理和数据加解密相关的服务；设备核心密钥生命周期不离开可信环境。可信环境同样可提供身份认证、系统状态监控、数据安全存储等安全服务，提高设备安全性。
+
+-   硬件密钥引擎
+
+    密码学是信息安全的基础。数据加解密对计算机设备的核心诉求是：高效、安全。硬件加解密技术利用计算机硬件辅助软件，甚至直接取代软件，来处理数据的加解密。相比由软件实现的加解密计算，硬件实现的加解密计算更高效、更安全。
+
+    由硬件来实现加解密处理，意味着部分专用的硬件资源会用于处理加解密计算任务，当加解密引擎工作的时候CPU可以并发地继续执行其他计算任务，因此硬件加解密引擎可以带来极大的性能提升，同时降低CPU负载。此外，硬件密钥引擎可以带来更高的安全性，设计良好的硬件密钥引擎，哪怕软件被攻破也依然可保护密钥不泄露，甚至可对抗电磁、辐射等物理侧信道攻击。
+
+    OpenHarmony设备支持硬件密钥引擎，支撑OpenHarmony系统进行数据加解密、证书验签、哈希计算等计算任务，可支持AES/RSA等主流的密码学算法。
+
+
+### 推荐做法<a name="section948519243104"></a>
+
+-   启动可信根可由一段固化在芯片中的代码和设备根密钥组成，前者一般在芯片制造阶段写入，设备生命周期内不可更改，负责在启动阶段校验设备软件证书；后者则是用于设备证书签名的私钥相对应的公钥，证书签名私钥不出PKI签名服务器，而公钥则需写入设备。为防止攻击者篡改公钥从而达到绕过签名认证的目的，写入OpenHarmony设备的公钥须确保不可篡改，可将公钥信息写入如熔丝等介质；考虑到熔丝空间有限，可仅存储公钥的哈希值，并由启动代码校验公钥的合法性。
+-   可信执行环境较为通用的做法是基于ARM TrustZone技术构建，也可根据设备的实际形态选择其他隔离机制，如TrustZone-M、独立安全核等；可信执行环境中须部署TEE OS，用于管理可信执行环境的资源及任务调度。OpenHarmony系统提供iTrustee作为TEE OS的解决方案，开发者及设备商可基于iTrustee开发并部署安全业务。
+
+    并非所有OpenHarmony设备都强制要求支持可信执行环境，部分运行低敏感业务的瘦资源设备可不做强制要求；可根据实际业务场景选择是否支持可信执行环境，以及实现怎样的可信执行环境。
+
+-   硬件密钥引擎须提供真随机数、公钥、对称密钥、哈希等密钥算法能力，通过在OpenHarmony系统中部署相应的驱动程序，给应用提供统一的密钥管理及密钥算法服务。

+### 安全机制<a name="section149107611118"></a>
+
+对于128KB\~128MB内存的设备，推荐使用OpenHarmony轻内核组件，在该内核下：
+
+-   进程隔离
+
+    进程隔离是为了防止A进程读写B进程内存数据的情况发生，进程的隔离技术，一般都采用虚拟地址空间映射方式，通过MMU配置，进程A的虚拟地址和进程B的虚拟地址映射各自不同的实际的物理地址段，这样A进程通过访问虚拟地址访问的实际内存数据在非共享内存的情况下，只属于A进程，B进程无法直接访问。
+
+    OpenHarmony由于资源有限，对于内核态和用户态的进程采用不同的方式：所有的内核态进程共享同一块VMM空间，即所有的内核态进程之间无隔离，系统启动时内核态创建两个基本进程KProcess和KIdle，KProcess进程为内核态进程的根进程，KIdle进程为KProcess进程的子进程；但是对于每一个用户态进程均拥有自己独立的VMM空间，相互之间不可见，实现进程间隔离。
+
+-   自主访问控制
+
+    自主访问控制DAC（Discretionary Access Control）的思想是文件权限由文件拥有者来决定其他角色的访问权限。权限管控粒度分为三类：user\(自身\)， group\(组员\)，other\(其他人\)，即UGO。将任意用户分类为UGO中三者之一，并采取相应的管控策略，即完成了DAC权限校验流程。
+
+    DAC机制依赖于进程的uid、gid等属性，需要以此作为文件创建以及文件访问过程中的特征id。文件创建时，创建者将自身uid写入文件，文件访问时，又以此作为文件归属的分类依据。
+
+    每一个应用，对应一个uid。应用在创建文件时，将自身uid信息加入被创建文件的元数据\(metadata\)中，并设置UGO三个组的权限。在文件访问过程中，将以访问者uid作为访问校验主体、以文件元数据中的uid权限信息作为客体，进行权限校验。
+
+    下图描述了DAC在文件访问时的鉴权过程，首先匹配进程uid和文件uid属性，其次匹配进程gid和文件gid属性，最后都匹配失败的情况，判断文件other属性是否支持进程的读、写、执行操作。同时支持忽略DAC检测机制（读、写、执行）作为一组系统特权（Capability），支持高权限（如系统服务）对低权限（三方APP）的文件管理。
+
+    **图 2**  DAC流程图<a name="fig37012315348"></a>  
+    ![](figure/DAC流程图.png "DAC流程图")
+
+-   Capability机制
+
+    Capability机制实际上是对root权限的具体细分。在多用户计算机系统中，一般会有一个特殊的角色拥有系统的所有权限，这个角色一般是系统管理员\(root\)。对于OpenHarmony这种需要支持三方应用生态的内核，需要将系统中的特权访问进行管控。系统需要对用户层访问内核的特权级系统调用进行限制。仅允许部分高权限应用进行特权操作。具体实现方式是内核spawn第一个用户程序INIT，其包含全部的特权能力，此后，INIT拉起其他应用框架服务，拉起过程中，对各应用框架进行相应的降权操作，为各应用保留必须的特权能力。 当应用去调用特权接口时，内核态就会通过进程ID查看当前访问者是否有权限访问目标接口。
+
+-   安全启动
+
+    安全启动是整个系统安全的基础，通过采用数字签名和完整性校验机制，从芯片内部固化的可信启动根开始，逐级校验每一层软件的完整性和合法性，确保最终启动的操作系统软件是厂家提供的正确合法的软件，防止攻击者对系统软件做恶意的篡改和植入，为整个系统提供初始安全的基础运行环境。
+
+    在芯片上电后，由于片上ROM代码本身不可更改，因此无需校验；片上ROM基于eFuse中的非对称算法公钥hash对bootloader进行校验。这些过程都基于硬件信任根来进行，是完全可信的。经过此过程校验通过的bootloader模块可以作为后续的信任基础，此过程就是启动信任链的构造过程。Bootloader通常首先对执行环境进行一定的初始化，主要是初始化DDR以及flash读写，为进一步加载后续模块以及执行更为复杂的逻辑进行准备。Bootloader完成初始化动作后，首先完成x509证书的完整性校验，然后利用x509证书的公钥对需要校验的镜像包（kernel.bin、teeOS.bin、rootfs.bin）进行校验。
+
+
+### 推荐做法<a name="section1364122019112"></a>
+
+-   自主访问控制和Capability机制是控制资源被谁可以访问的机制，建议所有权限设置都采用最小权限原则。
+-   安全启动必须要开启，信任根必须是基于芯片的不可更改的形式存在，并且在有安全升级的情况下，必须考虑安全升级后对于安全启动的影响，也就是安全升级后必须要更新对应镜像文件的签名信息或者hash值。
+
+## 数据安全<a name="section2468927364"></a>
+
+### 安全机制<a name="section1378993720111"></a>
+
+HUKS（Huawei  Universal Keystore Service），提供了密钥管理、证书管理服务，当前在OpenHarmony上主要提供密钥管理服务，用于支撑HiChain\(设备身份认证平台\)的基础设备认证。如下是HUKS的功能结构图：
+
+**图 3**  HUKS功能结构图<a name="fig10710452133411"></a>  
+![](figure/HUKS功能结构图.png "HUKS功能结构图")
+
+支持算法包括：
+
+-   认证加密：AES-128/192/256-GCM
+-   签名验签：ED25519
+-   密钥协商：X25519
+-   消息认证：HMAC-SHA256/512
+-   数据摘要：SHA256/512
+
+HUKS在使用中有如下约束：
+
+-   密钥安全存储：密钥要求存储于安全存储区域，数据不可以修改，恢复出厂设置时出厂预置的密钥不能被删除。
+-   密钥访问安全：OpenHarmony通过将不同应用数据保存在不同的位置，来实现应用间数据的隔离。通过参数结构体中包含UID和进程ID，来实现不同应用间的数据隔离。
+-   不支持并发访问：HUKS本身不考虑多个应用同时调用的情况，因为HUKS只是一个lib库，也不考虑资源的互斥。如果有多个应用都会用到HUKS服务，那么应该由每个应用各自链接一份HUKS库，并由业务传入持久化数据存储的路径，以实现应用间的数据存储分开。数据存储在各应用各自存储目录下。
+
+### 推荐做法<a name="section1531735481112"></a>
+
+对于设备认证功能，建议使用HiChain来对接HUKS，HUKS可以向HiChain等应用提供密钥的产生、导入、导出、加密/解密、存储、销毁，证书的导入和查询，秘密信息的存储等能力。
+
+## 设备互联安全<a name="section26153183616"></a>
+
+为了实现用户数据在设备互联场景下在各个设备之间的安全流转，需要保证设备之间相互正确可信，即设备和设备之间建立信任关系，并能够在验证信任关系后，搭建安全的连接通道，实现用户数据的安全传输。设备之间的信任关系在本文档中涉及IoT主控设备和IoT设备之间建立的可信关系。设备间可信关系建立的流程如下图所示：
+
+**图 4**  设备间建立可信关系流程图<a name="fig19592809415"></a>  
+![](figure/设备间建立可信关系流程图.png "设备间建立可信关系流程图")
+
+-   **IoT设备互联安全**
+
+    设备互联支持基于OpenHarmony的IoT设备（如AI音箱、智能家居、智能穿戴等设备）与IoT主控设备间建立点对点的信任关系，并在具备信任关系的设备间，搭建安全的连接通道，实现用户数据端到端加密传输。
+
+
+-   **IoT主控设备的IoT业务身份标识**
+
+    IoT主控设备为不同的IoT设备管理业务生成不同的身份标识，形成不同IoT管理业务间的隔离，该标识用于IoT主控设备与IoT设备之间的认证以及通信。IoT业务身份标识为椭圆曲线公私钥对（Ed25519公私钥对）。
+
+
+-   **IoT设备身份标识**
+
+    IoT设备会生成各自的设备身份标识，用来与IoT主控设备通信。该身份标识同样为椭圆曲线公私钥对（Ed25519公私钥对）；IoT设备私钥不出IoT设备，设备每次恢复出厂设置，会重置这个公私钥对。
+
+    上述身份标识可用于IoT主控设备与IoT设备间的安全通信：当IoT主控设备与IoT设备通过信任绑定流程交换业务身份标识或设备标识后，可以进行密钥协商并建立安全通信通道。
+
+
+-   **设备间点对点的信任绑定**
+
+    IoT主控设备和IoT设备建立点对点信任关系的过程，实际上是相互交换IoT设备的身份标识的过程。
+
+    在点对点建立信任关系的过程中，用户需要在IoT主控设备上，输入IoT设备上提供的PIN码：对于有屏幕的设备，该PIN码动态生成；对于没有屏幕的设备，该PIN码由设备生产厂家预置；PIN码的展示形式，可以是一个用户可读的数字，也可以是一个二维码。随后，IoT主控设备和IoT设备间使用PAKE协议完成认证和会话密钥协商过程，并在此基础上，通过协商出的会话密钥加密传输通道用于交换双方设备的身份标识公钥。
+
+
+-   **IoT主控设备与IoT设备间的通信安全**
+
+    当建立过信任关系的IoT主控设备与IoT设备间进行通信时，双方在完成上述信任关系绑定后，基于本地存储的对端身份公钥相互进行认证；在每次通信时基于STS协议完成双向身份认证以及会话密钥协商，之后设备使用此会话密钥加密双方设备间的传输通道。

+
+### 安全机制<a name="section55012136125"></a>
+
+-   应用签名管控
+
+    OpenHarmony应用的安装需要首先对包的完整性进行校验，具体策略是在开发阶段完成开发和调试后对安装包进行签名，这个签名需要使用指定的私钥，这个私钥就是跟验签用的公钥是一对的，一般的做法是OEM厂商生成一对公私钥，然后将公钥信息预置到设备中，而私钥就放在一个不联网的本地服务器上，这样可以确保私钥被泄露的风险尽量小，而应用在完成开发后就可以通过外置设备（例如USB）上传安装包到存放私钥的服务器上计算签名并下载签名结果到外置设备上。而安装应用时首先计算包的Hash值，一般采用SHA256算法，然后使用hash值和签名信息以及预置公钥进行验签，只有验签通过的应用才能安装。
+
+    除了要证明应用来自云端认证过的，还需要证明来源，即这个应用来自合法开发者开发的，具体做法是，开发者向云端申请开发证书，开发完成后，用开发证书进行自签名，设备端存放这个证书的上一级证书，所以安装过程中，对自签名信息做校验，确保开发者的合法性。
+
+-   应用权限控制
+
+    由于OpenHarmony系统允许安装三方应用，所以需要对三方应用的敏感权限调用进行管控，具体实现是应用在开发阶段就需要在profile.json中指明此应用在运行过程中可能会调用哪些敏感权限，这些权限包括静态权限和动态权限，静态权限表示只需要在安装阶段注册就可以，而动态权限一般表示获取用户的敏感信息，所以需要在运行时让用户确认才可以调用，授权方式包括系统设置应用手动授权等。除了运行时对应用调用敏感权限进行管控外，还需要利用应用签名管控手段确保应用安装包已经被设备厂商进行了确认。

-## 安全概述<a name="section1521410017353"></a>
-
-OpenHarmony操作系统是一个开放的系统，开发者可以通过OpenHarmony开发灵活的服务和应用，为开发者和使用者带来便利和价值。为了达到这一目的，OpenHarmony提供了一个可以有效保护应用和用户数据的执行环境。
-
-在这个执行环境中，芯片的安全能力、系统的安全能力、以及上层的安全服务一起协作，从硬件安全、系统安全、数据安全、设备互联安全、应用安全、安全更新多个维度提供安全保障。
-

-## 安全机制<a name="section1312953842210"></a>
-
--   启动可信根
-
-    OpenHarmony设备采用PKI（Public Key Infrastructure）体系保护软件完整性，确保设备运行来源合法、软件未被篡改。
-
-    在设备启动流程中，逐级进行软件签名校验形成安全启动链，任何一个环节的签名校验不通过即终止设备启动；安全启动链中最初执行签名校验的软硬件实体，需确保自身的合法、未被篡改。该实体即为设备的启动可信根。启动可信根可为固化在ROM中的一段代码，这段代码在芯片制造环节固化到芯片中，芯片制造完成后软件不可更改，在设备上电初始化的过程中，最先执行这段ROM中的代码，并由这段ROM代码执行后续的软件签名校验。
-
-    ROM中的代码在执行签名校验时，需确保用于校验的PKI公钥的合法性，OpenHarmony设备可采用eFuse/OTP等存储介质来存储公钥（如公钥哈希值），来保护公钥自身的合法性。公钥一般在设备制造环节，烧录到设备的eFuse/OTP中。
-
--   硬件隔离可信环境
-
-    硬件隔离的可信环境，遵循了可信计算系统的设计理念。可信环境内外形成了两个世界：可信世界与不可信世界，两者之间存在清晰而明确的隔离边界；OpenHarmony设备在可信环境中实现了核心敏感数据的保护机制，可确保即使不可信世界的操作系统存在漏洞且被利用，也依然能确保可信环境中敏感数据的安全。
-
-    OpenHarmony设备的可信环境，基于硬件的安全隔离机制构建，在不同的OpenHarmony设备上芯片隔离机制略有差异，较为通用的方法是采用ARM的TrustZone技术。在部分Risc-V芯片平台上，也可能采用独立安全核的形式来构建可信环境。
-
-    可信环境中，运行特定的、精简的操作系统iTrustee lite，用于管理可信环境的资源和任务调度，给OpenHarmony设备提供安全服务。密钥管理及数据安全，是可信环境中最为常见的安全服务，设备在eFuse/OTP中存有硬件唯一根密钥，可信环境可基于该密钥结合业务上下文衍生出多种密钥，给应用提供密钥管理和数据加解密相关的服务；设备核心密钥生命周期不离开可信环境。可信环境同样可提供身份认证、系统状态监控、数据安全存储等安全服务，提高设备安全性。
-
--   硬件密钥引擎
-
-    密码学是信息安全的基础。数据加解密对计算机设备的核心诉求是：高效、安全。硬件加解密技术利用计算机硬件辅助软件，甚至直接取代软件，来处理数据的加解密。相比由软件实现的加解密计算，硬件实现的加解密计算更高效、更安全。
-
-    由硬件来实现加解密处理，意味着部分专用的硬件资源会用于处理加解密计算任务，当加解密引擎工作的时候CPU可以并发地继续执行其他计算任务，因此硬件加解密引擎可以带来极大的性能提升，同时降低CPU负载。此外，硬件密钥引擎可以带来更高的安全性，设计良好的硬件密钥引擎，哪怕软件被攻破也依然可保护密钥不泄露，甚至可对抗电磁、辐射等物理侧信道攻击。
-
-    OpenHarmony设备支持硬件密钥引擎，支撑OpenHarmony系统进行数据加解密、证书验签、哈希计算等计算任务，可支持AES/RSA等主流的密码学算法。
-
-
-## 推荐做法<a name="section37901319112311"></a>
-
--   启动可信根可由一段固化在芯片中的代码和设备根密钥组成，前者一般在芯片制造阶段写入，设备生命周期内不可更改，负责在启动阶段校验设备软件证书；后者则是用于设备证书签名的私钥相对应的公钥，证书签名私钥不出PKI签名服务器，而公钥则需写入设备。为防止攻击者篡改公钥从而达到绕过签名认证的目的，写入OpenHarmony设备的公钥须确保不可篡改，可将公钥信息写入如熔丝等介质；考虑到熔丝空间有限，可仅存储公钥的哈希值，并由启动代码校验公钥的合法性。
--   可信执行环境较为通用的做法是基于ARM TrustZone技术构建，也可根据设备的实际形态选择其他隔离机制，如TrustZone-M、独立安全核等；可信执行环境中须部署TEE OS，用于管理可信执行环境的资源及任务调度。OpenHarmony系统提供iTrustee作为TEE OS的解决方案，开发者及设备商可基于iTrustee开发并部署安全业务。
-
-    并非所有OpenHarmony设备都强制要求支持可信执行环境，部分运行低敏感业务的瘦资源设备可不做强制要求；可根据实际业务场景选择是否支持可信执行环境，以及实现怎样的可信执行环境。
-
--   硬件密钥引擎须提供真随机数、公钥、对称密钥、哈希等密钥算法能力，通过在OpenHarmony系统中部署相应的驱动程序，给应用提供统一的密钥管理及密钥算法服务。

-
-对于128KB\~128MB内存的设备，推荐使用OpenHarmony轻内核组件，在该内核下：
-
--   进程隔离
-
-    进程隔离是为了防止A进程读写B进程内存数据的情况发生，进程的隔离技术，一般都采用虚拟地址空间映射方式，通过MMU配置，进程A的虚拟地址和进程B的虚拟地址映射各自不同的实际的物理地址段，这样A进程通过访问虚拟地址访问的实际内存数据在非共享内存的情况下，只属于A进程，B进程无法直接访问。
-
-    OpenHarmony由于资源有限，对于内核态和用户态的进程采用不同的方式：所有的内核态进程共享同一块VMM空间，即所有的内核态进程之间无隔离，系统启动时内核态创建两个基本进程KProcess和KIdle，KProcess进程为内核态进程的根进程，KIdle进程为KProcess进程的子进程；但是对于每一个用户态进程均拥有自己独立的VMM空间，相互之间不可见，实现进程间隔离。
-
--   自主访问控制
-
-    自主访问控制DAC（Discretionary Access Control）的思想是文件权限由文件拥有者来决定其他角色的访问权限。权限管控粒度分为三类：user\(自身\)， group\(组员\)，other\(其他人\)，即UGO。将任意用户分类为UGO中三者之一，并采取相应的管控策略，即完成了DAC权限校验流程。
-
-    DAC机制依赖于进程的uid、gid等属性，需要以此作为文件创建以及文件访问过程中的特征id。文件创建时，创建者将自身uid写入文件，文件访问时，又以此作为文件归属的分类依据。
-
-    每一个应用，对应一个uid。应用在创建文件时，将自身uid信息加入被创建文件的元数据\(metadata\)中，并设置UGO三个组的权限。在文件访问过程中，将以访问者uid作为访问校验主体、以文件元数据中的uid权限信息作为客体，进行权限校验。
-
-    下图描述了DAC在文件访问时的鉴权过程，首先匹配进程uid和文件uid属性，其次匹配进程gid和文件gid属性，最后都匹配失败的情况，判断文件other属性是否支持进程的读、写、执行操作。同时支持忽略DAC检测机制（读、写、执行）作为一组系统特权（Capability），支持高权限（如系统服务）对低权限（三方APP）的文件管理。
-
-    **图 2**  DAC流程图<a name="fig37012315348"></a>  
-    ![](figures/DAC流程图.png "DAC流程图")
-
--   Capability机制
-
-    Capability机制实际上是对root权限的具体细分。在多用户计算机系统中，一般会有一个特殊的角色拥有系统的所有权限，这个角色一般是系统管理员\(root\)。对于OpenHarmony这种需要支持三方应用生态的内核，需要将系统中的特权访问进行管控。系统需要对用户层访问内核的特权级系统调用进行限制。仅允许部分高权限应用进行特权操作。具体实现方式是内核spawn第一个用户程序INIT，其包含全部的特权能力，此后，INIT拉起其他应用框架服务，拉起过程中，对各应用框架进行相应的降权操作，为各应用保留必须的特权能力。 当应用去调用特权接口时，内核态就会通过进程ID查看当前访问者是否有权限访问目标接口。
-
--   安全启动
-
-    安全启动是整个系统安全的基础，通过采用数字签名和完整性校验机制，从芯片内部固化的可信启动根开始，逐级校验每一层软件的完整性和合法性，确保最终启动的操作系统软件是厂家提供的正确合法的软件，防止攻击者对系统软件做恶意的篡改和植入，为整个系统提供初始安全的基础运行环境。
-
-    在芯片上电后，由于片上ROM代码本身不可更改，因此无需校验；片上ROM基于eFuse中的非对称算法公钥hash对bootloader进行校验。这些过程都基于硬件信任根来进行，是完全可信的。经过此过程校验通过的bootloader模块可以作为后续的信任基础，此过程就是启动信任链的构造过程。Bootloader通常首先对执行环境进行一定的初始化，主要是初始化DDR以及flash读写，为进一步加载后续模块以及执行更为复杂的逻辑进行准备。Bootloader完成初始化动作后，首先完成x509证书的完整性校验，然后利用x509证书的公钥对需要校验的镜像包（kernel.bin、teeOS.bin、rootfs.bin）进行校验。
-
-
-## 推荐做法<a name="section45821048173613"></a>
-
--   自主访问控制和Capability机制是控制资源被谁可以访问的机制，建议所有权限设置都采用最小权限原则。
--   安全启动必须要开启，信任根必须是基于芯片的不可更改的形式存在，并且在有安全升级的情况下，必须考虑安全升级后对于安全启动的影响，也就是安全升级后必须要更新对应镜像文件的签名信息或者hash值。

-HUKS（Huawei  Universal Keystore Service），提供了密钥管理、证书管理服务，当前在OpenHarmony上主要提供密钥管理服务，用于支撑HiChain\(设备身份认证平台\)的基础设备认证。如下是HUKS的功能结构图：
-
-**图 3**  HUKS功能结构图<a name="fig10710452133411"></a>  
-![](figures/HUKS功能结构图.png "HUKS功能结构图")
-
-支持算法包括：
-
--   认证加密：AES-128/192/256-GCM
--   签名验签：ED25519
--   密钥协商：X25519
--   消息认证：HMAC-SHA256/512
--   数据摘要：SHA256/512
-
-HUKS在使用中有如下约束：
-
--   密钥安全存储：密钥要求存储于安全存储区域，数据不可以修改，恢复出厂设置时出厂预置的密钥不能被删除。
--   密钥访问安全：OpenHarmony通过将不同应用数据保存在不同的位置，来实现应用间数据的隔离。通过参数结构体中包含UID和进程ID，来实现不同应用间的数据隔离。
--   不支持并发访问：HUKS本身不考虑多个应用同时调用的情况，因为HUKS只是一个lib库，也不考虑资源的互斥。如果有多个应用都会用到HUKS服务，那么应该由每个应用各自链接一份HUKS库，并由业务传入持久化数据存储的路径，以实现应用间的数据存储分开。数据存储在各应用各自存储目录下。
-
-## 推荐做法<a name="section174640713306"></a>
-
-对于设备认证功能，建议使用HiChain来对接HUKS，HUKS可以向HiChain等应用提供密钥的产生、导入、导出、加密/解密、存储、销毁，证书的导入和查询，秘密信息的存储等能力。
-
-## 设备互联安全<a name="section26153183616"></a>
-
-为了实现用户数据在设备互联场景下在各个设备之间的安全流转，需要保证设备之间相互正确可信，即设备和设备之间建立信任关系，并能够在验证信任关系后，搭建安全的连接通道，实现用户数据的安全传输。设备之间的信任关系在本文档中涉及IoT主控设备和IoT设备之间建立的可信关系。设备间可信关系建立的流程如下图所示：
-
-**图 4**  设备间建立可信关系流程图<a name="fig19592809415"></a>  
-![](figures/设备间建立可信关系流程图.png "设备间建立可信关系流程图")
-
--   **IoT设备互联安全**
-
-    设备互联支持基于OpenHarmony的IoT设备（如AI音箱、智能家居、智能穿戴等设备）与IoT主控设备间建立点对点的信任关系，并在具备信任关系的设备间，搭建安全的连接通道，实现用户数据端到端加密传输。
-
-
--   **IoT主控设备的IoT业务身份标识**
-
-    IoT主控设备为不同的IoT设备管理业务生成不同的身份标识，形成不同IoT管理业务间的隔离，该标识用于IoT主控设备与IoT设备之间的认证以及通信。IoT业务身份标识为椭圆曲线公私钥对（Ed25519公私钥对）。
-
-
--   **IoT设备身份标识**
-
-    IoT设备会生成各自的设备身份标识，用来与IoT主控设备通信。该身份标识同样为椭圆曲线公私钥对（Ed25519公私钥对）；IoT设备私钥不出IoT设备，设备每次恢复出厂设置，会重置这个公私钥对。
-
-    上述身份标识可用于IoT主控设备与IoT设备间的安全通信：当IoT主控设备与IoT设备通过信任绑定流程交换业务身份标识或设备标识后，可以进行密钥协商并建立安全通信通道。
-
-
--   **设备间点对点的信任绑定**
-
-    IoT主控设备和IoT设备建立点对点信任关系的过程，实际上是相互交换IoT设备的身份标识的过程。
-
-    在点对点建立信任关系的过程中，用户需要在IoT主控设备上，输入IoT设备上提供的PIN码：对于有屏幕的设备，该PIN码动态生成；对于没有屏幕的设备，该PIN码由设备生产厂家预置；PIN码的展示形式，可以是一个用户可读的数字，也可以是一个二维码。随后，IoT主控设备和IoT设备间使用PAKE协议完成认证和会话密钥协商过程，并在此基础上，通过协商出的会话密钥加密传输通道用于交换双方设备的身份标识公钥。
-
-
--   **IoT主控设备与IoT设备间的通信安全**
-
-    当建立过信任关系的IoT主控设备与IoT设备间进行通信时，双方在完成上述信任关系绑定后，基于本地存储的对端身份公钥相互进行认证；在每次通信时基于STS协议完成双向身份认证以及会话密钥协商，之后设备使用此会话密钥加密双方设备间的传输通道。

--   应用签名管控
-
-    OpenHarmony应用的安装需要首先对包的完整性进行校验，具体策略是在开发阶段完成开发和调试后对安装包进行签名，这个签名需要使用指定的私钥，这个私钥就是跟验签用的公钥是一对的，一般的做法是OEM厂商生成一对公私钥，然后将公钥信息预置到设备中，而私钥就放在一个不联网的本地服务器上，这样可以确保私钥被泄露的风险尽量小，而应用在完成开发后就可以通过外置设备（例如USB）上传安装包到存放私钥的服务器上计算签名并下载签名结果到外置设备上。而安装应用时首先计算包的Hash值，一般采用SHA256算法，然后使用hash值和签名信息以及预置公钥进行验签，只有验签通过的应用才能安装。
-
-    除了要证明应用来自云端认证过的，还需要证明来源，即这个应用来自合法开发者开发的，具体做法是，开发者向云端申请开发证书，开发完成后，用开发证书进行自签名，设备端存放这个证书的上一级证书，所以安装过程中，对自签名信息做校验，确保开发者的合法性。
-
--   应用权限控制
-
-    由于OpenHarmony系统允许安装三方应用，所以需要对三方应用的敏感权限调用进行管控，具体实现是应用在开发阶段就需要在profile.json中指明此应用在运行过程中可能会调用哪些敏感权限，这些权限包括静态权限和动态权限，静态权限表示只需要在安装阶段注册就可以，而动态权限一般表示获取用户的敏感信息，所以需要在运行时让用户确认才可以调用，授权方式包括系统设置应用手动授权等。除了运行时对应用调用敏感权限进行管控外，还需要利用应用签名管控手段确保应用安装包已经被设备厂商进行了确认。

-## 推荐做法<a name="section1641420155381"></a>
-
-开发者在开发过程中需明确后续应用在运行时需要运行哪些权限，并在profile.json中进行注册，然后需要对应用进行签名，确保设备在安装这些应用时能对应用的完整性和来源进行校验。

-## 隐私保护概述<a name="section13200134331414"></a>
-
-随着互联网及信息化的发展，个人数据在社会经济和日常生活中发挥着越来越重要的作用。与此同时，个人数据泄露的风险也在增加，消费者产品开发者需要更加有效的保护用户的个人数据，提高用户对产品的信任度。为了提升消费者的隐私体验，产品应默认设置较高级别隐私保护策略，达到保护消费者隐私的目的。
-
-**基本概念**
-
--   **个人数据（Personal Data）**
-
-    与一个身份已被识别或者身份可被识别的自然人（“数据主体”）相关的任何信息；身份可识别的自然人是指其身份可以通过诸如姓名、身份证号、位置数据等识别码或者通过一个或多个与自然人的身体、生理、精神、经济、文化或者社会身份相关的特定因素来直接或者间接地被识别。个人数据包括：自然人的email地址、电话号码、生物特征（指纹）、位置数据、IP地址、医疗信息、宗教信仰、社保号、婚姻状态等。
-
--   **敏感个人数据（Sensitive Personal Data）**
-
-    敏感个人数据是个人数据的一个重要子集，指的是涉及数据主体的最私密领域的信息或者一旦泄露可能会给数据主体造成重大不利影响的数据。欧盟等国家和地区法律定义的敏感个人数据包括种族、政治观点、宗教和哲学信仰、工会成员资格、基因数据、生物信息、健康和性生活状况、性取向等。
-
-    根据业界最佳实践，敏感个人数据还包括可与自然人身份相关联的银行卡号、身份证号、护照号、口令等。敏感个人数据的处理需要更多更严格的保护措施。
-
--   **公开个人数据（Public available Personal Data）**
-
-    数据主体主动公开的个人数据，或公开网页/应用上可访问的个人数据，包括论坛公开的发帖、评论等。
-
--   **用户画像（User Profile）**
-
-    指对个人数据采取的任何自动化处理的方式，包括评估某个自然人特定方面的情况，尤其是为了分析和预测该自然人的工作表现、经济状况、健康、个人喜好、兴趣、可信度、行为举止、所在位置或行迹。
-
--   **数据控制者（Data Controller）**
-
-    单独或者与他人共同确定个人数据处理的目的和手段的自然人、法人、公共机构、政府部门或其他机构。
-
--   **数据处理者（Data Processor）**
-
-    指代表数据控制者处理个人数据的自然人、法人、公共机构、政府部门或其他机构。数据处理者必须按照数据控制者的要求对个人数据进行充分的保护。
-
--   **明示同意（Explicit consent）**
-
-    如下几种情形GDPR法律提到可以通过数据主体明示同意的方式合法地处理数据：
-
-    -   处理敏感个人数据。
-    -   自动化决策，包括进行用户画像。
-    -   向不具备充分保护水平的国家转移个人数据，并以同意作为合法性基础。
-
-    实现明示同意的方式有：
-
-    -   在收集特定数据时，弹出隐私声明告知个人数据处理相关事项，提供勾选框但不默认勾选，让数据主体勾选“我同意以上述方式处理我的个人数据”，或提供“我同意”的按钮让用户主动点击。
-    -   以书面的方式明确表达同意，数据主体在书面陈述上签字。
-    -   要求数据主体在系统中上传带有其签名的电子表格。
-    -   采取双重验证的方式，要求数据主体邮件形式回复同意后，再次点击用于验证的邮件链接或是输入SMS验证码。
-    -   用户主动输入的场景，例如用户主动输入身份证和银行卡号绑卡等场景。
-
-
-## 数据分类分级<a name="section2371104991511"></a>
-
-基于数据保护目标及风险后果，即数据遭到泄露或者遭到破坏带来的法律风险对个人、组织或公众的影响对数据进行定级，分为极高、高、中、低、公开五个数据级别。

-
-## 通用隐私设计规则<a name="section10354102411162"></a>
-
-为了指导厂商完成产品的隐私设计工作，我们整理了以下通用的隐私设计要求，作为OpenHarmony设备厂商产品隐私设计的指南和参考。
-
-**数据收集及使用公开透明**
-
-采集个人数据时，应清晰、明确地告知用户，并确保告知用户的个人信息将被如何使用。
-
--   针对不同等级的个人数据需要制定针对性的隐私处理策略。
-    -   敏感个人数据的采集需要获取数据主体明示同意。
-    -   一般个人数据的采集需要数据主体同意或基于其他合法授权。
-    -   非个人数据与中、高或极高级别个人数据关联采集，需要数据主体同意或其他合法授权，并在隐私声明中呈现。
-
--   应制定并遵从适当的隐私政策。在收集、使用留存和第三方分享用户个人数据时需要符合所有适用法律、政策和规定。如在收集个人数据前，需充分告知用户处理个人数据的种类、目的、处理方式、保留期限等，满足数据主体权利相关要求。
-
-    根据以上要求，我们设计了正确示例以供参考。隐私通知/声明的参考示例如下：
-
-    **图 1**  隐私通知/声明示例图<a name="fig1611815442274"></a>  
-    
-
-    ![](figures/2-应用启动预授权.png) ![](figures/3-应用隐私声明.png)
-
--   个人数据应当基于具体、明确、合法的目的收集，不应与此目的不相符的方式作进一步处理。对于收集目的变更和用户撤销同意后再次重新使用的场景都需要用户重新同意。隐私声明变更和撤销的示例如下图：
-
-    **图 2**  隐私通知/声明变更示例图<a name="fig3591610523"></a>  
-    
-
-    ![](figures/4-隐私声明变更通知.png)
-
-    **图 3**  撤销同意示例图<a name="fig12802152515583"></a>  
-    
-
-    ![](figures/6-1-隐私声明撤销.png) ![](figures/6-2-隐私声明撤销.png)
-
--   需要提供用户查看隐私声明的入口。例如，可以在应用的“关于”界面提供查看隐私声明的入口，如示例图所示：
-
-    **图 4**  隐私声明查看界面示例图<a name="fig11392538162011"></a>  
-    
-
-    ![](figures/5-应用隐私声明入口.png)
-
-
-**数据收集及使用最小化**
-
-个人数据收集应与数据处理目的相关，且是适当、必要的。开发者应尽可能对个人数据进行匿名化或假名化处理，降低对数据主体的风险。仅可收集和处理与特定目的相关且必需的个人数据，不能进行与特定目的不相关的进一步处理。
-
--   敏感权限申请的时候要满足权限最小化的要求，在申请权限时，只申请获取必需的信息或资源所需要的权限。如应用不需要相机权限就能够实现其功能时，则不应该向用户申请相机权限。
--   数据收集最小化：针对数据的收集要满足最小化要求，不收集与产品提供服务无关联的数据。如提供定位服务的产品，不应收集用户的网页浏览记录。
--   数据使用的功能要求能够使用户受益，收集的数据不能用于一些与用户正常使用无关的功能。数据收集不能有其他与用户正常使用无关的功能存在。如不得将“生物特征”、“健康数据”等敏感个人数据用于服务改进、投放广告或营销等非业务核心功能。
--   禁止在日志中打印敏感个人数据，如需要打印一般个人数据时，应对个人数据进行匿名化或假名化处理；
-
-    优先使用可以重置的标识符，如系统提供了NetworkID和DVID作为分布式场景下的设备标识符，广告业务场景下则建议使用[OAID](https://developer.huawei.com/consumer/cn/doc/development/HMSCore-Guides/oaid-0000001050783198)，基于应用的分析则建议使用[ODID](https://developer.huawei.com/consumer/cn/doc/development/HMSCore-Guides/odid-0000001051063255)和[AAID](https://developer.huawei.com/consumer/cn/doc/development/HMSCore-Guides/aaid-0000001051142988)，其他需要唯一标识符的场景可以使用UUID接口生成；可重置的标识符不能满足业务需求时，才选择序列号和MAC地址等永久性标识符。
-
-
-**数据处理选择和控制**
-
-对个人数据处理必须要征得用户的同意或遵守其他适用的法律法规，用户对其个人数据要有充分的控制权。
-
--   获取用户敏感权限的授权：产品弹窗提醒，向用户呈现需要获取的权限和权限使用目的，用户可通过选择决定是否进行授权及指定授权的方式，让用户对产品权限的授予和个人数据使用做到透明、可知、可控。如下图所示：
-
-    **图 5**  敏感权限提示框示例图<a name="fig20776134521514"></a>  
-    
-
-    ![](figures/1-敏感权限弹窗.png)
-
--   用户可以修改、取消授予的权限：当用户不同意某一权限或者数据收集时，应当允许用户使用与这部分权限和数据收集不相关的功能。如智慧屏产品上通信社交应用，用户可以拒绝授予相机权限，不应该影响与相机无关的功能操作，如语音通话。
--   用户在产品使用过程中，针对录入个人数据的场景，需要给用户提供对个人数据的增加、删除、修改、查看的操作。
--   需要给出硬件回收或返厂进行安全删除个人数据的机制或方法。
--   对用户系统软件、应用软件的下载或升级，涉及修改用户隐私空间，用户对于这类行为需要有知情权和控制权，必须给用户提示，并提供给用户同意和取消的选项。
-
-**数据安全**
-
-从技术上保证数据处理活动的安全性，包括个人数据的加密存储、安全传输等安全机制，系统应默认开启或采取安全保护措施。
-
--   对于个人数据的访问需要有保护机制，主要包括身份认证和访问控制。身份认证（如用户名、密码）限定只有经过认证的用户才能访问数据，可应用于多用户场景；访问控制（如[权限控制](安全指南.md#li201725506375)）可应用于对应用程序的限制。
--   分布式设备个人数据安全存储要满足密钥管理和存储服务（HUKS：Huawei Universal Keystore）的要求，包括：密钥安全存储、数据安全存储。
--   个人数据在分布式设备间传输要满足设备间的信任绑定关系和数据传输通道的安全性要求。详细信息可以参考[设备互联安全](安全指南.md#section26153183616)。
--   认证凭证数据（密码、口令、指纹等）须加密存储。
-
-**本地化处理**
-
-用户数据优先在本设备进行处理，对于本设备无法处理的数据应尽可能在超级终端设备本地进行数据的处理，如果超级终端本地处理无法满足业务目的的，在数据离开超级终端设备本地时应尽可能选择匿名化。
-
-**未成年人数据保护要求**
-
-产品专门给未成年人设计的，或者产品收集用户年龄从而可以识别到是在收集未成年人的个人数据，需结合目标市场国家的法律，专门分析未成年人个人数据保护的问题，收集未成年人数据前需要征得监护人的同意。
-
-## 特殊品类要求<a name="section118861450201618"></a>
-
-针对消费者硬件产品来说，除了满足以上的通用隐私要求以外，针对特殊品类的产品还有以下的特殊要求，在产品设计过程中参照执行。

-对Hi3518EV300/Hi3516DV300开源套件，在需要实现防回滚功能的版本中，需要增加LOCAL\_VERSION的值，如"ohos default 1.0"-\>"ohos default 1.1"，LOCAL\_VERSION在device\\hisilicon\\third\_party\\uboot\\u-boot-2020.01\\product\\hiupdate\\ota\_update\\ota\_local\_info.c中。
-
-示例，增加版本号
-
-```
-const char *get_local_version(void)
-{
-#if defined(CONFIG_TARGET_HI3516EV200) || \
-	defined(CONFIG_TARGET_HI3516DV300) || \
-	defined(CONFIG_TARGET_HI3518EV300)
-#define LOCAL_VERSION "ohos default 1.0" /* increase: default release version */
-```

-
--   [使用步骤](#section18816105182315)
-
-下面使用步骤以sensorTypeId为0的传感器为例，其他类型的传感器使用方式类似。
-
-## 使用步骤<a name="section18816105182315"></a>
-
-1.  导入需要的包
-
-```
-#include "sensor_agent.h"
-#include "sensor_agent_type.h"
-```
-
-1.  创建传感器回调函数
-
-```
-void SensorDataCallbackImpl(SensorEvent *event)
-{
-    if(event == NULL){
-        return;
-    }
-    float *sensorData=(float *)event->data;
-}
-```
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->回调函数的格式为RecordSensorCallback类型。
-
-1.  获取设备支持sensor列表
-
-```
-SensorInfo *sensorInfo = (SensorInfo *)NULL;
-int32_t count = 0;
-int32_t ret = GetAllSensors(&sensorInfo, &count);
-```
-
-1.  创建的传感器用户
-
-```
-SensorUser sensorUser;
-sensorUser.callback = SensorDataCallbackImpl; //成员变量callback指向创建的回调方法
-```
-
-1.  使能传感器
-
-```
-int32_t ret = ActivateSensor(0, &sensorUser);
-```
-
-1.  订阅传感器数据
-
-```
-int32_t ret = SubscribeSensor(0, &sensorUser);
-```
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->到这步就可以在实现的回调方法中获取到传感器数据。
-
-1.  取消传感器数据订阅
-
-```
-int32_t ret = UnsubscribeSensor(0, &sensorUser);
-```
-
-1.  去使能一个传感器
-
-```
-int32_t ret = DeactivateSensor(0, &sensorUser);
-```

-
-Sensor服务子系统提供了轻量级传感器服务基础框架，您可以使用该框架接口实现传感器列表查询、传感器控制、传感器订阅去订阅等功能。轻量级传感器服务框架如下图所示：
-
-**图1**  Sensor服务框架图
-
-![](figures/zh-cn_image_0000001077724150.png)
-
--   Sensor API：提供传感器的基础API，主要包含查询传感器的列表、订阅/取消传感器数据、执行控制命令等，简化应用开发。
--   Sensor Framework：主要实现传感器的订阅管理、数据通道的创建、销毁等，实现与传感器服务层的通信。
--   Sensor Service：主要实现HDF层数据接收、解析、分发，对设备传感器的管理，数据上报管理以及传感器权限管控等。

-## 简介<a name="section465982318513"></a>
-
-XTS子系统是OpenHarmony生态认证测试套件的集合，当前包括acts（application compatibility test suite）应用兼容性测试套件，后续会拓展dcts（device compatibility test suite）设备兼容性测试套件等。
-
-XTS子系统当前包括acts与tools软件包：
-
--   acts，存放acts相关测试用例源码与配置文件，其目的是帮助终端设备厂商尽早发现软件与OpenHarmony的不兼容性，确保软件在整个开发过程中满足OpenHarmony的兼容性要求。
--   tools，存放acts相关测试用例开发框架。
-
-## 系统类型<a name="section125090457443"></a>
-
-OpenHarmony支持如下几种系统类型：
-
--   轻量系统（mini system）
-
-    面向MCU类处理器例如Arm Cortex-M、RISC-V 32位的设备，硬件资源极其有限，支持的设备最小内存为128KiB，可以提供多种轻量级网络协议，轻量级的图形框架，以及丰富的IOT总线读写部件等。可支撑的产品如智能家居领域的连接类模组、传感器设备、穿戴类设备等。
-
--   小型系统（small system）
-
-    面向应用处理器例如Arm Cortex-A的设备，支持的设备最小内存为1MiB，可以提供更高的安全能力、标准的图形框架、视频编解码的多媒体能力。可支撑的产品如智能家居领域的IP Camera、电子猫眼、路由器以及智慧出行域的行车记录仪等。
-
--   标准系统（standard system）
-
-    面向应用处理器例如Arm Cortex-A的设备，支持的设备最小内存为128MiB，可以提供增强的交互能力、3D GPU以及硬件合成能力、更多控件以及动效更丰富的图形能力、完整的应用框架。可支撑的产品如高端的冰箱显示屏。

-### C语言用例开发编译指导（适用于轻量系统产品用例开发）<a name="section198193336544"></a>
-
-**示例：轻量系统测试用例开发**
-
-当前使用的测试框架是hctest，hctest测试框架支持使用C语言编写测试用例，是在开源测试框架unity的基础上进行增强和适配。
-
-1.  用例目录规范：测试用例存储到test/xts/acts仓中
-
-    ```
-    ├── acts
-    │ └──subsystem_lite
-    │ │ └── module_hal
-    │ │ │ └── BUILD.gn
-    │ │ │ └── src
-    │ └──build_lite
-    │ │ └── BUILD.gn
-    ```
-
-2.  src目录下用例编写样例。
-
-    1.引用测试框架
-
-    ```
-    #include "hctest.h"
-    ```
-
-    2. 使用宏定义LITE\_TEST\_SUIT定义子系统、模块、测试套件名称
-
-    ```
-    /**  
-    * @brief  register a test suit named "IntTestSuite"  
-    * @param  test subsystem name  
-    * @param  example module name  
-    * @param  IntTestSuite test suit name  
-    */
-    LITE_TEST_SUIT(test, example, IntTestSuite);
-    ```
-
-    3. 定义Setup与TearDown
-
-    命名方式：测试套件名称+Setup，测试套件名称+TearDown。
-
-    Setup与TearDown必须存在，可以为空函数。
-
-    4. 使用宏定义LITE\_TEST\_CASE写测试用例
-
-    包括三个参数：测试套件名称，测试用例名称，用例属性（测试类型、用例粒度、用例级别）。
-
-    ```
-    LITE_TEST_CASE(IntTestSuite, TestCase001, Function | MediumTest | Level1) 
-    {  
-      //do something 
-    };
-    ```
-
-    5. 使用宏定义 RUN\_TEST\_SUITE注册测试套件
-
-    ```
-    RUN_TEST_SUITE(IntTestSuite);
-    ```
-
-3.  测试模块的配置文件（BUILD.gn）样例：
-
-    在每个测试模块目录下新建BUILD.gn编译文件，用于指定编译后静态库的名称、依赖的头文件、依赖的库等；具体写法如下：
-
-    ```
-    import("//test/xts/tools/lite/build/suite_lite.gni")
-    hctest_suite("ActsDemoTest") {
-        suite_name = "acts"
-        sources = [
-            "src/test_demo.c",
-        ]
-        include_dirs = [ ]
-        cflags = [ "-Wno-error" ]
-    }
-    ```
-
-4.  acts下BUILD.gn增加编译选项。
-
-    需要将测试模块加入到acts目录下的编译脚本中，编译脚本路径：test/xts/acts/build\_lite/BUILD.gn。
-
-    ```
-    lite_component("acts") {  
-        ...
-        if(board_name == "liteos_m") {
-            features += [    
-                ...
-                "//xts/acts/subsystem_lite/module_hal:ActsDemoTest"
-            ]    
-        }
-    }
-    ```
-
-5.  测试套件编译命令。
-
-    随版本编译，debug版本编译时会同步编译acts测试套件
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >acts测试套件编译中间件为静态库，最终链接到版本镜像中 。
-
-
-### C语言用例执行指导（适用于轻量系统产品用例开发）<a name="section13820233175418"></a>
-
-**示例：轻量系统测试用例执行**
-
-将版本镜像烧录进开发板。
-
-**测试步骤**
-
-1.  使用串口工具登录开发板，并保存串口打印信息。
-2.  重启设备，查看串口日志。
-
-**测试结果分析指导**
-
-基于串口打印日志进行分析；
-
-每个测试套件执行以Start to run test suite开始，以xx Tests xx Failures xx Ignored结束。
-
-### C++语言用例开发编译指导（适用于小型系统、标准系统用例开发）<a name="section3822123311540"></a>
-
-**示例：小型系统测试用例开发**（标准参考具体样例目录：global/i18n\_standard）
-
-当前使用的测试框架是hcpptest，hcpptest测试框架是在开源的googletest测试框架的基础上进行的增强和适配。
-
-1.  规范用例目录：测试用例存储到test/xts/acts仓中。
-
-    ```
-    ├── acts
-    │ └──subsystem_lite
-    │ │ └── module_posix
-    │ │ │ └── BUILD.gn
-    │ │ │ └── src
-    │ └──build_lite
-    │ │ └── BUILD.gn
-    ```
-
-2.  测试模块src下用例编写样例：
-
-    1. 引用测试框架：
-
-    需要引用gtest.h  如：\#include "gtest/gtest.h"
-
-    ```
-    #include "gtest/gtest.h"
-    ```
-
-    2. 定义Setup与TearDown
-
-    ```
-    using namespace std;
-    using namespace testing::ext;
-    class TestSuite: public testing::Test {
-    protected:
-    // Preset action of the test suite, which is executed before the first test case
-    static void SetUpTestCase(void){
-    }
-    // Test suite cleanup action, which is executed after the last test case
-    static void TearDownTestCase(void){
-    }
-    // Preset action of the test case
-    virtual void SetUp()
-    {
-    }
-    // Cleanup action of the test case
-    virtual void TearDown()
-    {
-    }
-    };
-    ```
-
-    3. 使用宏定义HWTEST或HWTEST\_F写测试用例
-
-    普通测试用例的定义：HWTEST（测试套名称， 测试用例名称， 用例标注）。
-
-    包含SetUp和TearDown的测试用例的定义 ：HWTEST\_F（测试套名称， 测试用例名称，用例标注）。
-
-    宏定义包括三个参数：测试套件名称，测试用例名称，用例属性（测试类型、用例粒度、用例级别）。
-
-    ```
-    HWTEST_F(TestSuite, TestCase_0001, Function | MediumTest | Level1) {
-    // do something
-    }
-    ```
-
-3.  测试模块下用例配置文件（BUILD.gn）样例：
-
-    每个测试模块目录下新建BUILD.gn编译文件，用于指定编译后可执行文件的名称、依赖的头文件、依赖的库等；具体写法如下。每个测试模块将独立编译成.bin可执行文件， 该文件可直接push到单板上进行测试。
-
-    举例：
-
-    ```
-    import("//test/xts/tools/lite/build/suite_lite.gni")
-    hcpptest_suite("ActsDemoTest") {
-        suite_name = "acts"
-        sources = [
-            "src/TestDemo.cpp"
-        ]
-    
-        include_dirs = [
-            "src",
-            ...
-        ]
-        deps = [
-            ...
-        ]
-        cflags = [ "-Wno-error" ]
-    }
-    
-    ```
-
-4.  acts目录下增加编译选项（BUILD.gn）样例：
-
-    将测试模块加入到acts目录下的编译脚本中，编译脚本为：test/xts/acts/build\_lite/BUILD.gn。
-
-    ```
-     lite_component("acts") {  
-    ...
-    else if(board_name == "liteos_a") {
-            features += [
-                ...
-                "//xts/acts/subsystem_lite/module_posix:ActsDemoTest"
-            ]
-        }
-    }
-    ```
-
-5.  测试套件编译命令。
-
-    随版本编译，debug版本编译时会同步编译acts测试套件

-### C++语言用例执行指导（适用于小型系统、标准系统用例开发）<a name="section128222336544"></a>
-
-**示例：小型系统测试用例执行**
-
-目前的用例执行采用nfs共享的方式，mount到单板去执行。
-
-**环境搭建**
-
-1.  使用有限网线或无线将开发板与PC进行连接。
-2.  开发板配置IP、子网掩码、网关，确保开发板与PC处于同一个网段。
-3.  PC安装nfs服务器并完成注册，启动nfs服务。
-4.  开发板配置mount命令，确保开发板可以访问PC端的nfs共享文件。
-
-    格式：mount \[nfs服务器IP\]:\[/nfs共享目录\] \[/开发板目录\] nfs
-
-    举例：
-
-    ```
-    mount 192.168.1.10:/nfs /nfs nfs
-    ```
-
-
-**用例执行**
-
-测试套件执行 ActsDemoTest.bin 触发用例执行，基于串口打印日志进行分析。
-
-### JS语言用例开发指导（适用于标准系统）<a name="section159801435165220"></a>
-
-当前使用的测试框架是HJSUnit，用于支撑OpenHarmony application测试（特指基于JS应用框架使用 Javascript 语言开发的 APP）进行自动化测试。
-
-**用例编写基础语法**
-
-测试用例为 js 语言，必须满足 JavaScript 语言编程规范:

-
-bytrace是开发人员用于追踪进程轨迹、分析性能的一种工具，主要对内核ftrace进行了封装和扩展，来支持用户态的打点。通过该工具可以打开想要查看的用户态和内核label（通过下面命令行bytrace -l，查看支持的所有label），然后通过命令行进行抓取trace信息到指定文件中。

-### bytrace命令使用举例<a name="section5402591174"></a>
-
-以下是常用bytrace命令示例，供开发者参考：
-
--   查询支持的label。
-
-```
-bytrace -l  
-```
-
-或者
-
-```
-bytrace --list_categories
-```
-
--   设置4M缓存，抓取10秒，抓取label为ability的trace信息。
-
-```
-bytrace -b 4096 -t 10 --overwrite ability > /data/mytrace.ftrace
-```
-
--   设置trace的输出时钟为mono。
-
-```
-bytrace --trace_clock mono  -b 4096 -t 10 --overwrite ability > /data/mytrace.ftrace
-```
-
--   抓取trace后进行压缩。
-
-```
-bytrace -z  -b 4096 -t 10 --overwrite ability > /data/mytrace.ftrace
-```

-hdc\_std（OpenHarmony Device Connector）是OpenHarmony为开发人员提供的用于调试的命令行工具，通过该工具可以在Windows/Linux等系统上与开发机或者模拟器进行交互。
-
-下文将介绍hdc\_std的环境准备和常用命令及使用举例。
-
-## 环境准备<a name="section05992022154916"></a>
-
-**hdc\_std 工具获取方式：**
-
-从开源仓developtools\_hdc\_standard中获取，具体位置在该开源仓的prebuilt目录。
-
-**使用举例：**
-
-下面以windows侧使用方式举例：
-
-从prebuilt/windows侧获取可执行文件hdc\_std.exe，放到磁盘某个位置即可使用。
-
-## 注意事项<a name="section19543134915210"></a>
-
-1、使用hdc\_std，如果出现异常，可以尝试通过hdc\_std kill命令杀掉hdc\_std服务，或者通过hdc\_std start -r命令重启服务进程进行解决。
-
-2、如果出现hdc\_std list targets获取不到设备信息，通过任务管理器查看是否有hdc.exe进程存在，如果进程存在，可以通过杀掉该进程进行解决。
-
-## 全局option<a name="section618522925119"></a>

-使用方法：
-
-该option需要与具体的操作命令搭配使用，下面以shell命令举例：
-
-hdc\_std list targets  （获取设备信息）
-
-hdc\_std  -t   _key_   shell  （-t后面添加的_key_  需要替换为上面查询的设备信息）
-
->![](public_sys-resources/icon-note.gif) **说明：** 
->一台开发机可支持多个设备连接，每个设备有其唯一的设备标识，如果通过网络与设备连接,其标识为tcp:port格式，如果通过usb连接则标识为设备sn号。该命令需要跟随具体操作命令。

-## hdc\_std连接不到设备<a name="section1221016541119"></a>
-
--   **现象描述**
-
-    执行 "hdc\_std list targets"命令后结果为：\[Empty\]
-
--   **可能原因和解决方法**
-    1.  设备没有被识别：
-
-        在设备管理器中查看是否有hdc设备，在通用串行总线设备中会有“HDC Device”信息。如果没有，hdc无法连接。此时需要插拔设备，或者烧写最新的镜像。
-
-    2.  hdc\_std工作异常：
-
-        可以执行"hdc kill"或者"hdc start -r"杀掉hdc服务或者重启hdc服务，然后再执行hdc list targets查看是否已经可以获取设备信息。
-
-        如果一直获取不到设备信息，请在任务管理器中查询是否有adb进程，该进程可能会对hdc产生干扰，可以将其杀掉后重复执行上面的步骤。

-    3.  hdc\_std与设备不匹配：
-
-        如果设备烧写的是最新镜像，hdc\_std也需要使用最新版本。由于hdc\_std会持续更新，请从开源仓developtools\_hdc\_standard中获取，具体位置在该开源仓的prebuilt目录。

-## hdc\_std运行不了<a name="section219185710311"></a>
-
--   **现象描述**
-
-    点击hdc\_std.exe文件无法运行。
-
--   **可能原因和解决方法**
-
-    hdc\_std.exe不需要安装，直接放到磁盘上就能使用，也可以添加到环境变量中。通过打开cmd执行hdc\_std命令直接使用。

+# 唤醒词识别SDK的开发示例<a name="ZH-CN_TOPIC_0000001090776709"></a>
+
+1.  在//foundation/ai/engine /interfaces/kits目录中添加唤醒词识别SDK的API接口定义，该接口可用三方应用的调用。如下代码片段即为唤醒词识别定义的API接口示例，其相关代码参考路径为：//foundation/ai/engine /interfaces/kits/asr/keyword\_spotting。
+
+    ```
+    class KWSSdk {
+    public:
+        KWSSdk();
+        virtual ~KWSSdk();
+    
+        // 定义了创建唤醒词检测工具包的方法
+        int32_t Create();
+    
+        // 定义了同步执行唤醒词检测任务的方法
+        int32_t SyncExecute(const Array<int16_t> &audioInput);
+    
+        // 定义了设置唤醒词检测回调器的方法
+        int32_t SetCallback(const std::shared_ptr<KWSCallback> &callback);
+    
+        // 定义了销毁唤醒词工具包的方法，释放与插件的会话信息。
+        int32_t Destroy();
+    };
+    ```
+
+2.  在//foundation/ai/engine/services/client/algorithm\_sdk的目录中增加SDK中API接口的具体实现，调用client端提供的接口，实现算法插件能力的使用。如下代码片段即为唤醒词识别的API接口中create方法的具体实现示例，更多详细代码可参考：//foundation/ai/engine/services/client/algorithm\_sdk/asr/keyword\_spotting。
+
+    ```
+    int32_t KWSSdk::KWSSdkImpl::Create()
+    {
+        if (kwsHandle_ != INVALID_KWS_HANDLE) {
+            HILOGE("[KWSSdkImpl]The SDK has been created");
+            return KWS_RETCODE_FAILURE;
+        }
+        if (InitComponents() != RETCODE_SUCCESS) {
+            HILOGE("[KWSSdkImpl]Fail to init sdk components");
+            return KWS_RETCODE_FAILURE;
+        }
+        // 调用client端提供的接口AieClientInit，实现初始化引擎服务，激活跨进程调用
+        int32_t retCode = AieClientInit(configInfo_, clientInfo_, algorithmInfo_, nullptr);
+        if (retCode != RETCODE_SUCCESS) {
+            HILOGE("[KWSSdkImpl]AieClientInit failed. Error code[%d]", retCode);
+            return KWS_RETCODE_FAILURE;
+        }
+        if (clientInfo_.clientId == INVALID_CLIENT_ID) {
+            HILOGE("[KWSSdkImpl]Fail to allocate client id");
+            return KWS_RETCODE_FAILURE;
+        }
+        DataInfo inputInfo = {
+            .data = nullptr,
+            .length = 0,
+        };
+        DataInfo outputInfo = {
+            .data = nullptr,
+            .length = 0,
+        };
+        // 调用client端提供的接口AieClientPrepare，实现加载算法插件
+        retCode = AieClientPrepare(clientInfo_, algorithmInfo_, inputInfo, outputInfo, nullptr);
+        if (retCode != RETCODE_SUCCESS) {
+            HILOGE("[KWSSdkImpl]AieclientPrepare failed. Error code[%d]", retCode);
+            return KWS_RETCODE_FAILURE;
+        }
+        if (outputInfo.data == nullptr || outputInfo.length <= 0) {
+            HILOGE("[KWSSdkImpl]The data or length of output info is invalid");
+            return KWS_RETCODE_FAILURE;
+        }
+        MallocPointerGuard<unsigned char> pointerGuard(outputInfo.data);
+        retCode = PluginHelper::UnSerializeHandle(outputInfo, kwsHandle_);
+        if (retCode != RETCODE_SUCCESS) {
+            HILOGE("[KWSSdkImpl]Get handle from inputInfo failed");
+            return KWS_RETCODE_FAILURE;
+        }
+        return KWS_RETCODE_SUCCESS;
+    }
+    ```
+
+    上述代码为API接口的具体实现，从上述示例的代码中，SDK中create接口的具体实现即为下述示例代码中create方法，该方法调用了AI引擎框架client端开放接口AieClientInit，AieClientPrepare，从而实现与server端建立连接及加载算法模型的能力。
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >SDK调用AI引擎client端接口顺序应遵循AieClientInit-\>AieClientPrepare-\>AieClientSyncProcess/AieClientAsyncProcess-\>AieClientRelease-\>AieClientDestroy，否则调用接口会返回错误码。

+# 开发示例<a name="ZH-CN_TOPIC_0000001077767514"></a>
+
+以开发唤醒词识别为例，开发者可在Hi3516DV300开发板上，基于AI引擎框架开发唤醒词识别的sdk以及唤醒词识别的plugin，通过编译命令编出新的版本镜像并将其烧入版本。同时，开发者开发唤醒词识别的应用，该应用能够接收外部音频，将listen到的音频传入SDK中的接口，若音频中带有关键词，唤醒词识别的应用会识别出相应的词语，并打印在命令行中。
+
+本示例中唤醒词识别的场景中唤醒词是固定的，当开发者传入的音频包含”Hi，小问“，启动的应用就会打印"\[Hi, xiaowen\]"，当不包含时，会打印'\[UNKNOWN\]"。

+
+AI业务子系统是OpenHarmony提供原生的分布式AI能力的子系统。AI业务子系统提供了统一的AI引擎框架，实现算法能力快速插件化集成。框架中主要包含插件管理、模块管理和通信管理等模块，完成对AI算法能力的生命周期管理和按需部署。插件管理主要实现插件的生命周期管理及插件的按需部署,快速集成AI能力插件；模块管理主要实现任务的调度及管理客户端的实例；通信管理主要实现客户端和服务端之间的跨进程通信及引擎与插件之间的数据传输。后续，会逐步定义统一的AI能力接口，便于AI能力的分布式调用。同时，提供适配不同推理框架层级的统一推理接口。AI引擎框架如下[图1](#fig143186187187)所示。

+
+AI引擎框架包含client、server和common三个主要模块，其中client提供server端连接管理功能，北向SDK在算法对外接口中需封装调用client提供的公共接口；server提供插件加载以及任务管理等功能，各Plugin实现由server提供的插件接口，完成插件接入；common提供与平台相关的操作方法、引擎协议以及相关工具类，供其他各模块调用。
+
+AI引擎框架各模块之间的代码依赖关系如下[图1](#fig171811112818)所示：
+
+**图 1** ****AI引擎代码依赖关系<a name="fig171811112818"></a>

+

+
+## 建议：插件与北向SDK在AI引擎指定的路径下进行代码开发<a name="section17176374131"></a>
+
+在AI引擎框架的整体规划中，北向SDK属于client端的一部分，插件由server端调用，属于server端的一部分，因此AI引擎框架为接入的插件与北向SDK规划的路径：
+
+-   SDK代码路径：//foundation/ai/engine/services/client/algorithm\_sdk
+
+    e.g. //foundation/ai/engine/services/client/algorithm\_sdk/cv
+
+    e.g. //foundation/ai/engine/services/client/algorithm\_sdk/nlu
+
+-   插件代码路径：//foundation/ai/engine/services/server/plugin
+
+    e.g. //foundation/ai/engine/services/server/plugin/cv
+
+    e.g. //foundation/ai/engine/services/server/plugin/nlu
+
+
+## 规则：插件提供的全部对外接口，统一存放在AI业务子系统interfaces/kits目录<a name="section2551029111312"></a>
+
+北向SDK对外接口是AI业务子系统提供能力的对外暴露方式，按照OpenHarmony的接口管理要求，需统一存放在各子系统的interfaces/kits目录中。当前AI业务子系统插件对外接口路径为//foundation/ai/engine/interfaces/kits，不同插件可在该路径下添加目录，比如增加cv插件，则在路径//foundation/ai/engine/interfaces/kits/cv下面存放接口文件。
+
+## 规则：插件编译输出路径必须是在/usr/lib<a name="section97021558121310"></a>
+
+server端加载插件是采用dlopen方式，只支持在/usr/lib路径进行，因此插件在编译so时，需要在编译配置文件中指定输出路径为/usr/lib。

+## 开发步骤<a name="section10514141679"></a>
+
+### 创建Service类型的Ability<a name="section19921154214315"></a>
+
+1.  在my\_service\_ability.h中创建Ability的子类MyServiceAbility。
+
+    ```
+    class MyServiceAbility: public Ability {
+    protected:
+        void OnStart(const Want& want);
+        const SvcIdentity *OnConnect(const Want &want) override;
+        void MsgHandle(uint32_t funcId, IpcIo *request, IpcIo *reply) override;
+    };
+    ```
+
+2.  调用REGISTER\_AA宏将ServiceAbility注册到应用框架中，以便应用框架实例化开发者的MyServiceAbility。
+
+    ```
+    #include "my_service_ability.h"
+    
+    REGISTER_AA(ServiceAbility)
+    
+    void MyServiceAbility::OnStart(const Want& want)
+    {
+        printf("ServiceAbility::OnStart\n");
+        Ability::OnStart(want);
+    }
+    
+    const SvcIdentity *MyServiceAbility::OnConnect(const Want &want)
+    {
+        printf("ServiceAbility::OnConnect\n");
+        return Ability::OnConnect(want);
+    }
+    
+    void MyServiceAbility::MsgHandle(uint32_t funcId, IpcIo *request, IpcIo *reply)
+    {
+        printf("ServiceAbility::MsgHandle, funcId is %u\n", funcId);
+        int result = 0;
+        if (funcId == 0) {
+            result = IpcIoPopInt32(request) + IpcIoPopInt32(request);
+        }
+        // push data
+        IpcIoPushInt32(reply, result);
+    }
+    ```
+
+3.  实现Service相关的生命周期方法。Service也是一种Ability，Ability为服务提供了以下生命周期方法，用户可以重写这些方法来添加自己的处理。用户在重写的方法里，需要调用父类对应的方法。
+    -   OnStart\(\)
+
+        该方法在创建Service的时候调用，用于做一些Service初始化且耗时较短的工作，在Service的整个生命周期只会调用一次。
+
+        ```
+        void MyServiceAbility::OnStart(const Want& want)
+        {
+            printf("ServiceAbility::OnStart\n");
+            Ability::OnStart(want);
+        }
+        ```
+
+    -   OnConnect​\(\)
+
+        在组件和服务连接时调用，该方法返回SvcIdentity，组件可以通过它，与服务交互。
+
+        ```
+        const SvcIdentity *MyServiceAbility::OnConnect(const Want &want)
+        {
+            printf("ServiceAbility::OnConnect\n");
+            return Ability::OnConnect(want);
+        }
+        ```
+
+    -   OnDisconnect​\(\)
+
+        在组件与绑定的Service断开连接时调用。
+
+    -   OnStop\(\)
+
+        在Service销毁时调用。Service应通过实现此方法来清理任何资源，如关闭线程、注册的侦听器等。
+
+
+4.  重写消息处理方法。
+
+    MsgHandle是Service用来处理客户端消息的方法。其中funcId是客户端传过来的消息类型，request是客户端传过来的序列化请求参数。如果用户在处理完成之后想要把结果传回去，需要把结果序列化后写入reply中。
+
+    ```
+    void ServiceAbility::MsgHandle(uint32_t funcId, IpcIo *request, IpcIo *reply)
+    {
+        printf("ServiceAbility::MsgHandle, funcId is %d\n", funcId);
+        int result = 0;
+        if (funcId == PLUS) {
+            result = IpcIoPopInt32(request) + IpcIoPopInt32(request);
+        }
+        // push data
+        IpcIoPushInt32(reply, result);
+    }
+    ```
+
+5.  注册Service。
+
+    Service也需要在应用清单文件config.json中进行注册，注册类型type需要设置为service。
+
+    ```
+    "abilities": [{
+        "name": "ServiceAbility",
+        "icon": "res/drawable/phone.png",
+        "label": "test app 2", 
+        "launchType": "standard",
+        "type": "service",
+        "visible": true
+    }
+    ]
+    ```
+
+6.  启动Service。
+    -   Ability为用户提供了StartAbility\(\)方法来启动另外一个Ability，因为Service也是Ability的一种，开发者同样可以通过将Want传递给该方法来启动Service。
+
+        开发者可以通过Want的SetWantElement \(\)来设置目标服务信息。ElementName结构体的两个主要参数：第一个参数为包名称；第二个参数为目标Ability。
+
+        ```
+        {
+            Want want = { nullptr };
+            ElementName element = { nullptr };
+            SetElementBundleName(&element, "com.company.appname");
+            SetElementAbilityName(&element, "ServiceAbility");
+            SetWantElement(&want, element);
+            StartAbility(want);
+            ClearElement(&element);
+            ClearWant(&want);
+        }
+        ```
+
+        StartAbility\(\) 方法会立即执行，如果Service尚未运行，则系统首先会调用OnStart\(\)。
+
+    -   停止Service。
+
+        Service一旦创建就会一直保持在后台运行，开发者可以通过调用StopAbility\(\)来停止Service。
+
+
+7.  连接Service。
+    -   如果Service需要与Page Ability或其他应用组件中的Service进行交互，则应创建用于连接的Service。Service支持其他Ability通过ConnectAbility\(\)与其进行连接，ConnectAbility\(\)需要传入目标Service的Want，以及IAbilityConnection的实例来处理回调。IAbilityConnection提供了两个方法供用户实现，OnAbilityConnectDone\(\)用来处理连接的回调，OnAbilityDisconnectDone\(\)用来处理断开连接的回调。
+
+        ```
+        {
+            // ability创建IAbilityConnection对象和定义IAbilityConnection的两个方法实现
+            IAbilityConnection abilityConnection = new IAbilityConnection();
+            abilityConnection->OnAbilityConnectDone = OnAbilityConnectDone;
+            abilityConnection->OnAbilityDisconnectDone = OnAbilityDisconnectDone;
+         
+            void OnAbilityConnectDone(ElementName *elementName, SvcIdentity *serviceSid, 
+                int resultCode, void *data)
+            {
+                if (resultCode != 0) {
+                    return;
+                }
+                // push data
+                IpcIo request;
+                char dataBuffer[IPC_IO_DATA_MAX];
+                IpcIoInit(&request, dataBuffer, IPC_IO_DATA_MAX, 0);
+                IpcIoPushInt32(&request, 10);
+                IpcIoPushInt32(&request, 6);
+         
+                // send and getReply
+                IpcIo reply;
+                uintptr_t ptr = 0;
+                if (Transact(nullptr, *serviceSid, 0, &request, &reply, 
+                    LITEIPC_FLAG_DEFAULT, &ptr) != LITEIPC_OK) {
+                    printf("transact error\n");
+                    return;
+                }
+                int result = IpcIoPopInt32(&reply);
+                printf("execute add method, result is %d\n", result);
+                if (ptr != 0) {
+                    FreeBuffer(nullptr, reinterpret_cast<void *>(ptr));
+                }
+            }
+         
+            void OnAbilityDisconnectDone(ElementName *elementName, 
+                int resultCode, void *data)
+            {
+                printf("elementName is %s, %s\n", 
+                    elementName->bundleName, elementName->abilityName);
+            }
+        }
+        ```
+
+    -   发起connect和disconnect。
+
+        ```
+        {
+            // ability发起connect
+            Want want = { nullptr };
+            ElementName element = { nullptr };
+            SetElementBundleName(&element, "com.company.appname");
+            SetElementAbilityName(&element, "ServiceAbility");
+            SetWantElement(&want, element);
+            ConnectAbility(want, *abilityConnection, this);
+         
+            // ability发起disconnect
+            DisconnectAbility(*abilityConnection);
+        }
+        ```

+### 包管理接口使用指导<a name="section1724016743217"></a>
+
+**安装应用**
+
+安装接口只能给内置的系统应用使用。根据应用的安装路径，可以在安装应用时进行选择：
+
+-   将应用安装到系统默认的文件目录/storage/app/。
+-   将应用安装到系统外挂的存储介质中，例如micro sdcard。
+
+这两种选择可以在创建InstallParam实例的时候指定，当InstallParam的成员变量installLocation为 INSTALL\_LOCATION\_INTERNAL\_ONLY时，意味着应用将会被安装到/storage/app/目录下；当InstallParam的成员变量installLocation为INSTALL\_LOCATION\_PREFER\_EXTERNAL时，意味着应用将被安装到存储介质，其安装目录是/sdcard/app/。由于安装应用的过程是异步的，所以需要使用类似信号量的机制来确保安装的回调可以被执行。
+
+安装应用的步骤如下（示例代码以安装到系统目录为例）：
+
+1.  将经过安全签名的应用放置于指定的目录下。
+2.  创建InstallParam实例和信号量。
+
+    ```
+    InstallParam installParam = { 
+    .installLocation = INSTALL_LOCATION_INTERNAL_ONLY, // 安装到系统目录
+    .keepData = false
+    };
+    static sem_t g_sem;
+    ```
+
+3.  定义回调函数。
+
+    ```
+    static void InstallCallback(const uint8_t resultCode, const void *resultMessage)
+    {
+         std::string strMessage = reinterpret_cast<const char *>(resultMessage);
+         if (!strMessage.empty()) {
+            printf("install resultMessage is %s, %d\n", strMessage.c_str(),resultCode);
+         }
+         sem_post(&g_sem);
+    }
+    ```
+
+4.  调用Install接口。
+
+    ```
+    const uint32_t WAIT_TIMEOUT = 30;
+    sem_init(&g_sem, 0, 0);
+    std::string installPath = “/storage/bundle/demo.hap”; // hap包的存储路径
+    bool result = Install(installPath.c_str(), &installParam, InstallCallback);
+    struct timespec ts = {};
+    clock_gettime(CLOCK_REALTIME, &ts);
+    ts.tv_sec += WAIT_TIMEOUT; // 超时即释放信号量
+    sem_timedwait(&g_sem, &ts);
+    ```
+
+
+**卸载应用**
+
+卸载应用的时候可以选择是否保留应用的数据，开发者可以通过创建的InstallParam实例的成员变量keepData来确定。当keepData为true, 卸载应用之后将保留应用的数据，当keepData为false时，卸载应用之后将不会保留应用的数据。
+
+1.  创建InstallParam实例和信号量。
+
+    ```
+    static sem_t g_sem;
+    InstallParam installParam = {
+    .installLocation = 1,
+         .keepData = false // 不保留应用数据
+    };
+    ```
+
+2.  定义回调函数。
+
+    ```
+    static void UninstallCallback(const uint8_t resultCode, const void *resultMessage)
+    {
+        std::string strMessage = reinterpret_cast<const char *>(resultMessage);
+        if (!strMessage.empty()) {
+            printf("uninstall resultMessage is %s\n", strMessage.c_str());
+            g_resultMessage = strMessage;
+        }
+        g_resultCode = resultCode;
+        sem_post(&g_sem);
+    }
+    ```
+
+3.  调用Uninstall接口。
+
+    ```
+    sem_init(&g_sem, 0, 0);
+    const uint32_t WAIT_TIMEOUT = 30;
+    std::string BUNDLE_NAME = “com.huawei.demo”; // 卸载应用的包名
+    Uninstall(BUNDLE_NAME.c_str(), &installParam, UninstallCallback);
+    struct timespec ts = {};
+    clock_gettime(CLOCK_REALTIME, &ts);
+    ts.tv_sec += WAIT_TIMEOUT;
+    sem_timedwait(&g_sem, &ts);
+    ```
+
+
+**查询已安装应用的包信息**
+
+开发者可以利用BundleManager提供的接口GetBundleInfo来查询系统内已安装应用的包信息。
+
+1.  创建以及初始化BundleInfo。
+
+    ```
+    BundleInfo bundleInfo;
+    (void) memset_s(&bundleInfo, sizeof(BundleInfo), 0, sizeof(BundleInfo));
+    ```
+
+2.  调用GetBundleInfo接口，指定查询应用的包名，同时指定flag来确定获取的BundleInfo中是否含有元能力信息（实例代码以含有元能力信息为例）。
+
+    ```
+    std::string BUNDLE_NAME = "com.huawei.demo";
+    uint8_t ret = GetBundleInfo(BUNDLE_NAME.c_str(), 1, &bundleInfo); // flags = 1，获取包信息中含有元能力信息
+    ```
+
+3.  使用完获取的BundleInfo之后，要及时清理掉其内部所占用的内存空间避免内存泄漏。
+
+    ```
+    ClearBundleInfo(&bundleInfo);
+    ```

+用户程序框架是OpenHarmony为开发者提供开发OpenHarmony应用的开发框架，包含两个模块：Ability子系统和包管理子系统。
+
+## 基本概念<a name="section72601941194812"></a>
+
+开发者在开发前需要先了解以下基本概念，方便开发者更好的理解OpenHarmony用户程序框架。
+
+## Ability子系统<a name="section14633111813374"></a>
+
+Ability子系统是管理OpenHarmony应用运行状态的开发框架。
+
+**图 1**  Ability子系统框架图<a name="fig9759195514371"></a>  
+![](figure/Ability子系统框架图.png "Ability子系统框架图")
+
+-   **Ability**：系统调度应用的最小单元，是能够完成一个独立功能的组件，一个应用可以包含一个或多个Ability。Ability分为两种类型：Page类型的Ability和Service类型的Ability。
+    -   **Page类型的Ability**：带有界面，为用户提供人机交互的能力。
+
+    -   **Service类型的Ability**：不带界面，为用户提供后台任务机制。
+
+
+
+-   **AbilitySlice**：单个页面及其控制逻辑的总和，是Page类型Ability特有的组件，一个Page类型的Ability可以包含多个AbilitySlice，此时，这些页面提供的业务能力应当是高度相关的。
+
+    **图 2**  Ability与AbilitySlice的关系图<a name="fig1065819910347"></a>  
+    ![](figure/Ability与AbilitySlice的关系图.png "Ability与AbilitySlice的关系图")
+
+-   **生命周期**：Ability被调度到启动、激活、隐藏和退出等各个状态的统称。
+
+    **图 3**  Ability生命周期流转<a name="fig56111543375"></a>  
+    
+
+    ![](figure/图片1.png)
+
+    -   **OnStart\(\)**
+
+        系统首次创建Page实例时触发该回调。对于一个Page实例，该回调在其生命周期过程中仅触发一次，Page在该逻辑后进入INACTIVE状态。开发者必须重写该方法，并在此配置默认展示的AbilitySlice。
+
+    -   **OnActive\(\)**
+
+        Page会在进入INACTIVE状态后来到前台，然后系统调用此回调。Page在此之后进入ACTIVE状态，该状态是应用与用户交互的状态。Page将保持在此状态，除非某类事件发生导致Page失去焦点，比如用户点击返回键或导航到其他Page。
+
+        当此类事件发生时，会触发Page回到INACTIVE状态，系统将调用OnInactive\(\)回调。此后，Page可能重新回到ACTIVE状态，系统将再次调用OnActive\(\)回调。因此，开发者通常需要成对实现OnActive\(\)和OnInactive\(\)，并在OnActive\(\)中获取在OnInactive\(\)中被释放的资源。
+
+    -   **OnInactive\(\)**
+
+        当Page失去焦点时，系统将调用此回调，此后Page进入INACTIVE状态。开发者可以在此回调中实现Page失去焦点时应表现的恰当行为。
+
+    -   **OnBackground\(\)**
+
+        如果Page不再对用户可见，系统将可能根据资源状况调用此回调，此后Page进入BACKGROUND状态。开发者应该在此回调中释放Page不可见时无用的资源，或在此回调中执行较为耗时的状态保存操作。
+
+    -   **OnForeground\(\)**
+
+        处于BACKGROUND状态的Page仍然驻留在内存中，当重新回到前台时（比如用户重新导航到此Page），系统将先调用OnForeground\(\)回调使Page回到INACTIVE状态，然后调用OnActive\(\)回调使Page回到ACTIVE状态。开发者应当在此回调中重新申请在OnBackground\(\)中释放的资源。轻量化设备目前不支持该接口。
+
+    -   **OnStop\(\)**
+

+-   **AbilityKit**：Ability框架提供给开发者的开发包，开发者基于该开发包可以开发出基于Ability组件的应用。基于Ability组件开发的应用有两种类型：基于Javascript语言开发的Ability（JS Ability）和基于C/C++语言开发的Ability（Native Ability）。JS应用开发框架是开发者开发JS Ability所用到框架，是在AbilityKit基础封装的包含js UI组件的一套方便开发者能够迅速开发Ability应用的框架。
+-   **AbilityLoader**：负责注册和加载开发者Ability的模块。开发者开发的Ability先要调用AbilityLoader的注册接口注册到框架中，接着Ability启动时会被实例化。
+
+-   **AbilityManager：**负责AbilityKit和Ability管理服务进行IPC的通信。
+
+-   **EventHandler**：AbilityKit提供给开发者的用于在Ability中实现线程间通信的一个模块。
+
+-   **AbilityManagerService**：元能力运行管理服务。该服务用于协调各Ability运行关系、及生命周期进行调度的系统服务。其中，服务启动模块负责Ability管理服务的启动、注册等。服务接口管理模块负责Ability管理服务对外能力的管理。进程管理模块负责Ability应用所在进程的启动和销毁、及其进程信息维护等功能。Ability栈管理模块负责维护各个Ability之间跳转的先后关系。生命周期调度模块是Ability管理服务根据系统当前的操作调度Ability进入相应的状态的模块。连接管理模块是Ability管理服务对Service类型Ability连接管理的模块
+
+-   **AppSpawn**：负责创建Ability应用所在进程的系统服务，该服务有较高的权限，为Ability应用设置相应的权限，并预加载一些通用的模块，加速应用的启动。
+
+
+## 包管理子系统<a name="section1341146154412"></a>
+
+包管理子系统是OpenHarmony为开发者提供的安装包管理框架。

+
+-   **BundleKit**：是包管理服务对外提供的接口，有安装/卸载接口、包信息查询接口、包状态变化listen接口。
+-   **包扫描器**：用来解析本地预制或者安装的安装包，提取里面的各种信息，供管理子模块进行管理，持久化。
+-   **包安装子模块**：安装，卸载，升级一个包；包安装服务是一个单独进程和包管理服务通过IPC进行通信，该服务用于创建、删除安装目录和数据目录等，具有较高的权限。
+
+-   **包管理子模块**：管理安装包相关的信息，存储持久化包信息。
+
+-   **包安全管理子模块**：签名检查、权限授予、权限管理。
+
+
+## 运作机制<a name="section94302021112717"></a>
+
+Ability子系统的核心模块是Ability管理服务、包管理子系统的核心模块是包管理服务，这两个服务是系统级服务，借助系统服务框架Samgr实现服务的注册与发现，并对其他进程提供Ability管理服务和包管理服务。Ability管理服务和包管理服务通过AbilityKit和BundleKit以接口的形式向外提供服务。

+## 系统启动过程中打印“parse failed!”错误后停止启动<a name="section2041345718513"></a>
+
+**现象描述**
+
+系统启动过程中，打印“\[Init\] InitReadCfg, parse failed! please check file /etc/init.cfg format.”错误，启动过程停止，如下图所示：
+
+![](figure/zh-cn_image_0000001063839940.png)
+
+**可能原因**
+
+修改init.cfg文件时，漏掉或多加了逗号或括号等，导致init.cfg文件的json格式被破坏。
+
+**解决办法**
+
+仔细检查init.cfg文件，确保其格式符合json格式要求。
+
+## 系统启动过程未结束就自动重启，如此反复持续<a name="section57381816168"></a>
+
+**现象描述**
+
+镜像烧写完成后系统启动，启动过程未完成即自动重新启动，如此反复持续。
+
+**可能原因**
+
+被init启动的服务都有一个叫做“importance”的属性（详见[第2章表3](subsys-boot-init.md#table14737791471)描述）。
+
+-   当该属性为0时，表示若当前服务进程退出，init不需要重启单板。
+-   当该属性为1时，表示若当前服务进程退出，init需要重启单板。
+
+因此出现上述现象的可能原因：有“importance”属性为1的服务在每次启动的过程中都会退出（可能是进程崩溃或出错自动退出），导致init进程自动重启单板。
+
+**解决办法**
+
+1.  需要通过日志确认崩溃或报错退出的服务，并解决其崩溃/报错的问题，然后重新烧写镜像即可。
+2.  也可以将崩溃/报错退出的服务的“importance”属性改为0，然后重新烧写镜像，这样即使其退出，init也不会重启单板。
+
+## 参数正确的情况下调用SetParameter/GetParameter返回失败<a name="section129991227141512"></a>
+
+**现象描述**
+
+在各参数正确的情况下调用SetParameter/GetParameter返回失败。
+
+**可能原因**
+
+程序对SetParameter/GetParameter这两个接口做了权限校验，在各参数正确的情况下调用SetParameter/GetParameter返回操作失败，很有可能是调用者的uid大于1000，没有调用权限。
+
+**解决办法**
+
+无需处理

+## 概述<a name="section10958256161119"></a>
+
+一个基于gn和ninja的构建系统，以支持OpenHarmony组件化开发为目标，提供以下基本功能：
+
+-   支持按组件拼装产品并编译。
+
+-   独立构建芯片解决方案厂商源码。
+-   独立构建单个组件。
+
+### 基本概念<a name="section1732301411128"></a>
+
+在使用编译构建子系统前，应了解如下基本概念：
+
+-   子系统
+
+    子系统是一个逻辑概念，它由一个或多个具体的组件组成。OpenHarmony整体遵从分层设计，从下向上依次为：内核层、系统服务层、框架层和应用层。系统功能按照“系统 \> 子系统 \> 组件”逐级展开，在多设备部署场景下，支持根据实际需求裁剪某些非必要的子系统或组件。
+
+
+-   组件
+
+    系统最小的可复用、可配置、可裁剪的功能单元。组件具备目录独立可并行开发、可独立编译、可独立测试的特征。
+
+-   gn
+
+    Generate ninja的缩写，用于产生ninja文件。
+
+-   ninja
+
+    ninja是一个专注于速度的小型构建系统。
+
+-   hb
+
+    OpenHarmony的命令行工具，用来执行编译命令。
+

+
+**图 1**  编译构建流程<a name="fig9744112715161"></a>  
+![](figure/编译构建流程.jpg "编译构建流程")
+
+1.  hb set: 设置OpenHarmony源码目录和要编译的产品。
+2.  hb build: 编译产品、开发板或者组件。编译主要过程如下：
+    -   读取编译配置：根据产品选择的开发板，读取开发板config.gni文件内容，主要包括编译工具链、编译链接命令和选项等。
+    -   调用gn：调用gn gen命令，读取产品配置生成产品解决方案out目录和ninja文件。
+    -   调用ninja：调用ninja -C out/board/product启动编译。
+    -   系统镜像打包：将组件编译产物打包，设置文件属性和权限，制作文件系统镜像。
+
+
+## 配置规则<a name="section2345183962710"></a>
+
+为了实现芯片解决方案、产品解决方案与OpenHarmony是解耦的、可插拔的，组件、芯片解决方案和产品解决方案的路径、目录树和配置需遵循一定的规则，具体如下：
+
+### **组件**<a name="section142532518308"></a>
+
+组件源码路径命名规则为：**\{领域\}/\{子系统\}/\{组件\}**，组件目录树规则如下：
+
+>![](../public_sys-resources/icon-caution.gif) **注意：** 
+>组件的名称、源码路径、功能简介、是否必选、编译目标、RAM、ROM、编译输出、已适配的内核、可配置的特性和依赖等属性定义在build/lite/components目录下对应子系统的json文件中，新增组件时需要在对应子系统json文件中添加相应的组件定义。产品所配置的组件必须在某个子系统中被定义过，否则会校验失败。
+
+```

+│   ├── innerkits  # 系统内接口，组件间使用
+│   └── kits       # 应用接口，应用开发者使用
+├── frameworks     # framework实现

+
+以泛sensor子系统的sensor服务组件为例，组件属性定义描述文件字段说明如下：
+
+```

+  "components": [
+    {
+      "component": "sensor_lite",                # 组件名称
+      "description": "Sensor services",          # 组件一句话功能描述

+        ],
+        "third_party": [                         # 组件依赖的三方开源软件
+          "bounds_checking_function"
+        ]
+      }
+    }
+  ]
+}
+```
+
+组件BUILD.gn的编写建议如下：
+
+-   编译目标名称与组件一致。
+-   组件对外可配置的特性变量需声明在该组件BUILD.gn中，特性变量命名规则：ohos\_\{subsystem\}\_\{component\}\_\{feature\}。特性在组件描述中也需要同步定义，在产品配置文件config.json中按需配置。
+-   宏定义规则：OHOS\_\{SUBSYSTEM\}\_\{COMPONENT\}\_\{FEATURE\}
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >组件的编译脚本语言为gn，gn的基本用法请见[gn快速入门](https://gn.googlesource.com/gn/+/master/docs/quick_start.md)。组件即为gn定义的编译目标，可以为静态库、动态库、可执行文件或group。
+
+
+以图形的UI组件为例，foundation/graphic/ui/BUILD.gn文件如下：
+
+```
+	# 声明组件可配置的特性
+	declare_args() {
+	  enable_ohos_graphic_ui_animator = false # 动效特性开关
+	  ohos_ohos_graphic_ui_font = "vector"    # 可配置的字体类型，vector或者bitmap
+	}
+	
+	# 组件基础功能
+	shared_library("base") {
+	  sources = [
+	    ......
+	  ]
+	  include_dirs = [
+	    ......
+	  ]
+	}
+	
+	# 仅在animator开启时编译
+	if(enable_ohos_graphic_ui_animator ) { 
+	  shared_library("animator") {
+	    sources = [
+	      ......
+	    ]
+	    include_dirs = [
+              ......
+	    ]
+	    deps = [ :base ]
+	  }
+	}
+	......
+	# target名称建议与组件名称一致, 组件target类型可以是executable(bin文件)，shared_library(动态库.so)，static_library(静态库.a)，group等等
+	executable("ui") {
+	  deps = [
+	    ":base"
+	  ]
+
+	  # animator特性由产品配置
+	  if(enable_ohos_graphic_ui_animator ) {
+	      deps += [
+	        "animator"
+	      ]
+	  }
+	}
+```

+### **芯片解决方案**<a name="section121501451143710"></a>
+
+-   芯片解决方案是指基于某款开发板的完整解决方案，包含驱动、设备侧接口适配、开发板sdk等。
+-   芯片解决方案是一个特殊的组件，源码路径规则为：**device/\{芯片解决方案厂商\}/\{开发板\}**。
+-   芯片解决方案组件会随产品选择的开发板默认编译。
+
+芯片解决方案目录树规则如下：
+
+```

+```
+
+>![](../public_sys-resources/icon-note.gif) **说明：** 
+>config.gni为开发板编译相关的配置，编译时会采用该配置文件中的参数编译所有OS组件，编译阶段系统全局可见。
+
+config.gni的关键字段介绍如下：
+
+```
+kernel_type:            开发板使用的内核类型，例如：“liteos_a”, “liteos_m”, “linux”。
+kernel_version:         开发使用的内核版本，例如：“4.19”。
+board_cpu:              开发板CPU类型，例如：“cortex-a7”, “riscv32”。
+board_arch:             开发芯片arch, 例如： “armv7-a”, “rv32imac”。
+board_toolchain:        开发板自定义的编译工具链名称，例如：“gcc-arm-none-eabi”。若为空，则使用默认为ohos-clang。
+board_toolchain_prefix：编译工具链前缀，例如：“gcc-arm-none-eabi”。
+board_toolchain_type：  编译工具链类型，目前支持gcc和clang。例如：“gcc” ，“clang”。
+board_cflags：          开发板配置的c文件编译选项。
+board_cxx_flags：       开发板配置的cpp文件编译选项。
+board_ld_flags：        开发板配置的链接选项。
+```
+
+### **产品解决方案**<a name="section134549283435"></a>
+
+产品解决方案为基于开发板的完整产品，主要包含产品对OS的适配、组件拼装配置、启动配置和文件系统配置等。产品解决方案的源码路径规则为：**vendor/\{产品解决方案厂商\}/\{产品名称\}**_。_产品解决方案也是一个特殊的组件。
+
+产品解决方案的目录树规则如下：
+
+```
+vendor                              
+└── company                         # 产品解决方案厂商

+```
+
+>![](../public_sys-resources/icon-caution.gif) **注意：** 
+>**新增产品须按如上的规则创建目录和文件，编译构建系统将按该规则扫描已配置的产品。**
+
+关键的目录和文件详细介绍如下：
+
+1.  **vendor/company/product/init\_configs/etc**
+
+    该文件夹中包含rcS脚本，Sxxx脚本和fstab脚本。init进程在启动系统服务之前执行这些脚本。执行的流程为“rcS-\>fstab-\>S00-xxx“。Sxxx脚本中的内容与开发板和产品需要有关，主要包括设备节点的创建、创建目录、扫描设备节点、修改文件权限等等。这些文件在产品编译的BUILD.gn中按需拷贝到产品out目录中，最终打包到rootfs镜像中。
+
+2.  **vendor/company/product/init\_configs/init.cfg**
+
+    init进程启动服务的配置文件，当前支持解析的命令有：
+
+    -   start:  启动某个服务
+    -   mkdir: 创建文件夹
+    -   chmod: 修改指定路径/文件的权限
+    -   chown: 修改指定路径/文件的属组
+    -   mount: 挂载命令
+
+    该文件中的各个字段的解释如下：
+
+    ```
+    {
+        "jobs" : [{                                                     # job数组，一个job对应一个命令集合。job的执行顺序：pre-init -> init -> post-init。

+    }
+    ```
+
+3.  **vendor/company/product/init\_configs/hals**
+
+    解决方案厂商对OS的适配，需要实现的接口请见各个组件的readme说明文档。
+
+4.  **vendor/company/product/config.json**
+
+    config.json为编译构建的主入口，包含了开发板、OS组件和内核等配置信息。
+
+    以基于hispark\_taurus开发板的ipcamera产品为例，配置文件如下：
+
+    ```
+    {
+    	"product_name": "ipcamera",                       # 产品名称
+    	"ohos_version": "OpenHarmony 1.0",                # 选择的OS版本
+    	"device_company": "hisilicon",                    # 芯片厂商
+    	"board": "hispark_taurus",                        # 开发板名称
+    	"kernel_type": "liteos_a",                        # 选择的内核类型
+    	"kernel_version": "3.0.0",                        # 选择的内核版本
+    	"subsystems": [                            
+    	  {
+    	    "subsystem": "aafwk",                         # 选择的子系统
+    	    "components": [
+    	      { "component": "ability", "features":[ "enable_ohos_appexecfwk_feature_ability = true" ] }   # 选择的组件和组件特性配置
+    	    ]
+    	  },
+    	  {
+    	   ......
+    	  }
+    	  ......
+    	  更多子系统和组件
+    	}
+    }
+    ```
+
+5.  **vendor/company/product/fs.yml**
+
+    该文件用于配置文件系统镜像制作过程，将编译产物打包成文件系统镜像，比如用户态根文件系统rootfs.img和可读写的userfs.img。它由多个列表组成，每个列表对应一个文件系统。字段说明如下：
+
+    ```
+    fs_dir_name： 必填，声明文件系统文件名, 如rootfs、userfs
+    fs_dirs：     选填，配置out下文件目录与文件系统文件目录的映射关系，每个文件目录对应一个列表
+    source_dir：  选填，out下目标文件目录，若缺失则将根据target_dir在文件系统下创建空目录
+    target_dir：  必填，文件系统下对应文件目录
+    ignore_files：选填，声明拷贝忽略文件
+    dir_mode：    选填，文件目录权限，默认755
+    file_mode：   选填，该文件目录下所有文件的权限，默认555
+    fs_filemode： 选填，配置需要特殊声明权限的文件，每个文件对应一个列表
+    file_dir：    必填，文件系统下具体文件路径
+    file_mode：   必填，文件权限声明
+    fs_symlink：  选填，配置文件系统软连接
+    fs_make_cmd： 必填，配置需要制作文件系统脚本，OS提供的脚本在build/lite/make_rootfs下, 支持linux，liteos内核和ext4、jffs2、vfat格式。也支持芯片解决方案厂商自定义。
+    fs_attr：     选填，根据配置项动态调整文件系统
+    ```
+
+    其中fs\_symlink、fs\_make\_cmd字段支持以下变量：
+
+    -   $\{root\_path\}
+
+        代码根目录，对应gn的$\{ohos\_root\_path\}
+
+    -   $\{out\_path\}
+
+        产品out目录，对应gn的$\{root\_out\_dir\}
+
+    -   $\{fs\_dir\}
+
+        文件系统目录，由以下变量拼接而成
+
+        -   $\{root\_path\}
+        -   $\{fs\_dir\_name\}
+
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >fs.yml是可选的，对于没有文件系统的设备可不配置。
+
+6.  **vendor/company/product/BUILD.gn**
+
+    产品编译的入口，主要用于编译解决方案厂商源码和拷贝启动配置文件。如果某个产品被选择为要编译的产品，那么对应产品目录下的BUILD.gn会默认编译。一个典型的产品编译BUILD.gn应该如下：
+
+    ```
+    group("product") { # target名称需与product名称即三级目录名称一致
+      deps = []
+      # 拷贝init配置
+      deps += [ "init_configs" ]
+      # 其他
+      ......
+    }
+    ```

+
+-   hb build后无参数，会按照设置好的代码路径、产品进行编译，编译选项使用与之前保持一致。-f 选项将删除当前产品所有编译产品，等同于hb clean + hb build.
+-   hb build \{component\_name\}：基于设置好的产品对应的单板、内核，单独编译组件（e.g.：hb build kv\_store\)。
+-   hb build -p ipcamera@hisilicon：免set编译产品，该命令可以跳过set步骤，直接编译产品。
+-   在device/device\_company/board下单独执行hb build会进入内核选择界面，选择完成后会根据当前路径的单板、选择的内核编译出仅包含内核、驱动的镜像。
+
+**hb clean**
+
+清除out目录对应产品的编译产物，仅保留args.gn、build.log。清除指定路径可输入路径参数：hb clean out/board/product，默认将清除当前hb set的产品对应out路径。
+
+```
+hb clean
+usage: hb clean [-h] [out_path]
+
+positional arguments:
+  out_path    clean a specified path.
+

+```
+
+### 新增组件<a name="section167110415315"></a>
+
+本小节介绍如何新增一个组件，首先确定组件归属的子系统和组件名称，然后按如下步骤新增：
+
+1.  源码开发完成后，添加组件编译脚本。
+
+    以编译组件hello\_world可执行文件为例，applications/sample/hello\_world/BUILD.gn可以写为：
+
+    ```
+    executable("hello_world") {
+      include_dirs = [
+        "include",
+       ]
+      sources = [
+        "src/hello_world.c"
+      ]
+    }
+    ```
+
+    如上编译脚本，可编译出一个可在OpenHarmony上运行的名为hello\_world的可执行文件。
+
+    单独编译该组件，hb set任意选择一款产品，然后使用-T选项单独编译组件：
+
+    ```
+    hb build -f -T //applications/sample/hello_world
+    ```
+
+    组件在开发板上功能验证完成后，可按[步骤2\~4](#li11471037297)将组件配置到产品中。
+
+2.  <a name="li11471037297"></a>添加组件描述。
+
+    组件描述位于build/lite/components下，新增的组件需加入对应子系统的json文件中。一个组件描述必选的字段有：
+
+    -   component：组件名称。
+    -   description：组件的一句话功能描述。
+    -   optional：组件是否为系统可选。
+    -   dirs：组件源码路径。
+    -   targets：组件编译入口。
+
+    以将hello\_world组件加入应用子系统为例，在applications.json中添加hello\_world对象：
+
+    ```
+    {
+      "components": [
+        {
+          "component": "hello_world",
+          "description": "Hello world.",
+          "optional": "true",
+          "dirs": [
+            "applications/sample/hello_world"
+          ],
+          "targets": [
+            "//applications/sample/hello_world"
+          ]
+        },
+        ...
+       ]
+    }
+    ```
+
+3.  将组件配置到产品。
+
+    产品的配置文件config.json位于位于vendor/company/product/下，产品配置文件需包含产品名称、OpenHarmony版本号、device厂商、开发板、内核类型、内核版本号，以及配置的子系统和组件。以将hello\_world组件加入产品配置文件my\_product.json中为例，加入hello\_wolrd对象：
+
+    ```
+    {
+        "product_name": "hello_world_test",
+        "ohos_version": "OpenHarmony 1.0",
+        "device_company": "hisilicon",
+        "board": "hispark_taurus",
+        "kernel_type": "liteos_a",
+        "kernel_version": "1.0.0",
+        "subsystems": [
+          {
+            "subsystem": "applications",
+            "components": [
+              { "component": "hello_world", "features":[] }
+            ]
+          },
+          ...
+        ]
+    }
+    ```
+
+4.  编译产品。
+
+    1. 代码根目录输入hb set选择对应产品。
+
+    2. 执行hb build。
+
+
+### 新增芯片解决方案<a name="section1474718565412"></a>
+
+编译构建支持添加新的芯片解决方案厂商，具体步骤如下：
+
+1.  创建芯片解决方案目录。
+
+    按照[芯片解决方案配置规则](#section1625463413327)创建目录，以芯片厂商realtek的“rtl8720“开发板为例, 在代码根目录执行：
+
+    ```
+    mkdir -p device/realtek/rtl8720
+    ```
+
+2.  创建内核适配目录，并编写开发板编译配置config.gni文件。
+
+    以realtek的“rtl8720“开发板的liteos\_m适配为例，device/realtek/rtl8720/liteos\_a/config.gni的内容如下：
+
+    ```
+    # Kernel type, e.g. "linux", "liteos_a", "liteos_m".
+    kernel_type = "liteos_a"
+    
+    # Kernel version.
+    kernel_version = "3.0.0"
+    
+    # Board CPU type, e.g. "cortex-a7", "riscv32".
+    board_cpu = "real-m300"
+    
+    # Board arch, e.g. "armv7-a", "rv32imac".
+    board_arch = ""
+    
+    # Toolchain name used for system compiling.
+    # E.g. gcc-arm-none-eabi, arm-linux-harmonyeabi-gcc, ohos-clang, riscv32-unknown-elf.
+    # Note: The default toolchain is "ohos-clang". It's not mandatory if you use the default toochain.
+    board_toolchain = "gcc-arm-none-eabi"
+    
+    # The toolchain path instatlled, it's not mandatory if you have added toolchian path to your ~/.bashrc.
+    board_toolchain_path =
+        rebase_path("//prebuilts/gcc/linux-x86/arm/gcc-arm-none-eabi/bin",
+                    root_build_dir)
+    
+    # Compiler prefix.
+    board_toolchain_prefix = "gcc-arm-none-eabi-"
+    
+    # Compiler type, "gcc" or "clang".
+    board_toolchain_type = "gcc"
+    
+    # Board related common compile flags.
+    board_cflags = []
+    board_cxx_flags = []
+    board_ld_flags = []
+    ```
+
+3.  编写编译脚本。
+
+    在开发板目录下创建BUILD.gn，target名称应与开发板名称一致。以realtek的rtl8720开发板为例，device/realtek/rtl8720/BUILD.gn内容可以是：
+
+    ```
+    group("rtl8720") { # target类型也可以shared_library, static_library, executable
+      # 具体内容
+      ......
+    }
+    ```
+
+4.  编译芯片解决方案。
+
+    在开发板目录下执行hb build，即可启动芯片解决方案的编译。
+
+
+### 新增产品解决方案<a name="section1097623294220"></a>
+
+编译构建支持芯片解决方案和组件的灵活拼装，形成定制化的产品解决方案。具体步骤如下：
+
+1.  创建产品目录
+
+    按照[产品解决方案配置规则](#section1625463413327)创建产品目录，以基于“rtl8720“开发板的wifiiot模组为例，在代码根目录执行：
+
+    ```
+    mkdir -p vendor/my_company/wifiiot
+    ```
+
+2.  拼装产品
+
+    在新建的产品目录下新建config.json文件，以步骤1中的wifiiot为例，vendor/my\_company/wifiiot/config.json可以是：
+
+    ```
+    {
+        "product_name": "wifiiot",                        # 产品名称
+        "ohos_version": "OpenHarmony 1.0",                # 使用的OS版本
+        "device_company": "realtek",                      # 芯片解决方案厂商名称
+        "board": "rtl8720",                               # 开发板名称
+        "kernel_type": "liteos_m",                        # 选择的内核类型
+        "kernel_version": "3.0.0",                        # 选择的内核版本
+        "subsystems": [                            
+          {
+            "subsystem": "kernel",                        # 选择的子系统
+            "components": [
+              { "component": "liteos_m", "features":[] }  # 选择的组件和组件特性
+            ]
+          },
+          ...
+          {
+             更多子系统和组件
+          }
+        ]
+    }
+    ```
+
+    注意：编译构建系统编译前会对device\_company，board，kernel\_type，kernel\_version、subsystem、component字段进行有效性检查，其中device\_company，board，kernel\_type，kernel\_version应与已知的芯片解决方案匹配，subsystem、component应与build/lite/components下的组件描述匹配。
+
+3.  适配OS接口
+
+    在产品目录下创建hals目录，并将产品解决方案对OS适配的源码和编译脚本放入该目录下。
+
+4.  配置系统服务
+
+    在产品目录下创建init\_configs目录，并在init\_configs目录下创建init.cfg文件，按需配置要启动的系统服务。
+
+5.  配置init进程（仅linux内核需要）
+
+    在init\_configs目录下创建etc目录，然后在etc下创建init.d文件夹和fstab文件。最后按产品需求在init.d文件下创建并编辑rcS文件和Sxxx文件。
+
+6.  配置文件系统镜像（可选，仅支持文件系统的开发板需要）
+
+    在产品目录下创建fs.yml文件。fs.yml需按产品实际情况配置，一个典型的fs.yml文件如下：
+
+    ```
+    -
+      fs_dir_name: rootfs # 镜像的名称
+      fs_dirs:
+        -
+          # 将编译生成的out/my_board/my_product/bin目录下的文件拷贝到rootfs/bin中，并忽略测试bin
+          source_dir: bin
+          target_dir: bin
+          ignore_files:
+            - Test.bin
+            - TestSuite.bin
+        -
+          # 将编译生成的out/my_board/my_product/libs目录下的文件拷贝到rootfs/lib中，忽略所有.a文件，并设置文件和文件夹的权限为644和755
+          source_dir: libs
+          target_dir: lib
+          ignore_files:
+            - .a
+          dir_mode: 755
+          file_mode: 644
+        -
+          source_dir: usr/lib
+          target_dir: usr/lib
+          ignore_files:
+            - .a
+          dir_mode: 755
+          file_mode: 644
+        -
+          source_dir: config
+          target_dir: etc
+        -
+          source_dir: system
+          target_dir: system
+        -
+          source_dir: sbin
+          target_dir: sbin
+        -
+          source_dir: usr/bin
+          target_dir: usr/bin
+        -
+          source_dir: usr/sbin
+          target_dir: usr/sbin
+        -
+          # 创建一个proc空目录
+          target_dir: proc
+        -
+          target_dir: mnt
+        -
+          target_dir: opt
+        -
+          target_dir: tmp
+        -
+          target_dir: var
+        -
+          target_dir: sys
+        -
+          source_dir: etc
+          target_dir: etc
+        -
+          source_dir: vendor
+          target_dir: vendor
+        -
+          target_dir: storage
+    
+      fs_filemode:
+        -
+          file_dir: lib/ld-uClibc-0.9.33.2.so
+          file_mode: 555
+        -
+          file_dir: lib/ld-2.24.so
+          file_mode: 555
+        -
+          file_dir: etc/init.cfg
+          file_mode: 400
+      fs_symlink:
+        -
+          # 在rootfs/lib下创建软连接ld-musl-arm.so.1 -> libc.so
+          source: libc.so
+          link_name: ${fs_dir}/lib/ld-musl-arm.so.1
+        -
+          source: mksh
+          link_name: ${fs_dir}/bin/sh
+        -
+          source: mksh
+          link_name: ${fs_dir}/bin/shell
+      fs_make_cmd:
+        # 使用脚本将rootfs制作为ext4格式的image
+        - ${root_path}/build/lite/make_rootfs/rootfsimg_linux.sh ${fs_dir} ext4
+    -
+      fs_dir_name: userfs
+      fs_dirs:
+        -
+          source_dir: storage/etc
+          target_dir: etc
+        -
+          source_dir: data
+          target_dir: data
+      fs_make_cmd:
+        - ${root_path}/build/lite/make_rootfs/rootfsimg_linux.sh ${fs_dir} ext4
+    
+    ```
+
+7.  配置产品Patch（可选，视产品涉及组件是否需要打补丁而定）
+
+    在产品目录下创建patch.yml文件。patch.yml需按产品实际情况配置，一个典型的patch.yml文件如下：
+
+    ```
+    # 需要打patch的路径
+    foundation/communication/dsoftbus:
+      # 该路径下需要打的patch存放路径
+      - foundation/communication/dsoftbus/1.patch
+      - foundation/communication/dsoftbus/2.patch
+    third_party/wpa_supplicant:
+      - third_party/wpa_supplicant/1.patch
+      - third_party/wpa_supplicant/2.patch
+      - third_party/wpa_supplicant/3.patch
+    ...
+    ```
+
+    配置完成后，编译时增加--patch参数，即可在产品编译前将配置的Patch文件打到对应目录中，再进行编译：
+
+    ```
+    hb build -f --patch
+    ```
+
+8.  编写编译脚本
+
+    在产品目录下创建BUILD.gn文件，按产品实际情况编写脚本。以步骤1中的wifiiot为例，BUILD.gn示例如下：
+
+    ```
+    group("wifiiot") { # target名称与产品名一致
+      deps = []
+      # 拷贝init配置
+      deps += [ "init_configs" ]
+      # 将hals加入编译
+      deps += [ "hals" ]
+      # 其他
+      ......
+    }
+    ```
+
+9.  编译产品。
+
+    在代码根目录执行hb set按提示选择新增的产品，然后执行hb build即可启动编译。

+## 概述<a name="section17466112012244"></a>
+
+编译构建子系统提供了一个基于gn和ninja的编译构建框架。主要提供以下功能：
+
+-   构建不同芯片平台的产品。如：Hi3516DV300平台。
+
+-   根据产品配置可以按照组件组装打包产品需要的能力。
+
+### 基本概念<a name="section445513507246"></a>
+
+在了解编译构建子系统的能力前，应了解如下基本概念：
+
+-   平台
+
+    开发板和内核的组合，不同平台支持的子系统和组件不同。
+
+-   子系统
+
+    OpenHarmony整体遵从分层设计，从下向上依次为：内核层、系统服务层、框架层和应用层。系统功能按照“系统 \> 子系统 \> 组件”逐级展开，在多设备部署场景下，支持根据实际需求裁剪某些非必要的子系统或组件。子系统是一个逻辑概念，它具体由对应的组件构成。
+
+-   组件
+
+    对子系统的进一步拆分，可复用的软件单元，它包含源码、配置文件、资源文件和编译脚本；能独立构建，以二进制方式集成，具备独立验证能力的二进制单元。
+
+-   gn
+
+    Generate ninja的缩写，用于产生ninja文件。
+
+-   ninja
+
+    ninja是一个专注于速度的小型构建系统。
+
+
+### 运作机制<a name="section12541217142510"></a>
+
+OpenHarmony侧的编译构建流程主要包括编译命令行解析，调用gn，执行ninja：
+
+-   命令行解析：解析待编译的产品名称，加载相关配置。
+-   调用gn: 根据命令行解析的产品名称和编译类型，配置编译工具链和全局的编译选项。
+-   执行ninja：启动编译并生成对应的产品版本。
+
+### 约束与限制<a name="section886933762513"></a>
+
+-   需按照[源码获取](../get-code/sourcecode-acquire.md)指导下载全量源码（采用方式三获取）。
+-   编译环境需要Ubuntu18.04及以上版本。
+-   安装编译所需的程序包。
+
+    安装命令：
+
+    ```
+    sudo apt-get install binutils git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4
+    ```

+    ```
+
+    \{product\_name\}为当前版本支持的平台。比如：Hi3516DV300等。
+
+    编译完成后，结果镜像保存在 out/ohos-arm-release/packages/phone/images/ 目录下。
+
+-   编译命令支持选项：
+
+    ```
+      --product-name    # 必须  编译的产品名称，如：Hi3516DV300
+      --build-target    # 可选  指定编译目标，可以指定多个
+      --gn-args         # 可选  gn参数，支持指定多个
+      --ccache          # 可选  编译使用ccache，需要本地安装ccache
+    ```
+
+
+### 开发步骤<a name="section591084422719"></a>
+
+1.  添加组件。
+
+    本节以添加一个自定义的组件为例，描述如何编译组件，编译库、编译可执行文件等。
+
+    示例组件partA由feature1、feature2和feature3组成，feature1的编译目标为一个动态库，feature2的目标为一个可执行程序，feature3的目标为一个etc配置文件。
+
+    示例组件partA的配置需要添加到一个子系统中，本次示例将添加到subsystem\_examples子系统中（subsystem\_examples子系统定义在test/examples/目录）。
+
+    示例组件partA的完整目录结构如下：
+
+    ```
+    test/examples/partA
+    ├── feature1
+    │   ├── BUILD.gn
+    │   ├── include
+    │   │   └── helloworld1.h
+    │   └── src
+    │       └── helloworld1.cpp
+    ├── feature2
+    │   ├── BUILD.gn
+    │   ├── include
+    │   │   └── helloworld2.h
+    │   └── src
+    │       └── helloworld2.cpp
+    └── feature3
+        ├── BUILD.gn
+        └── src
+            └── config.conf
+    ```
+
+    示例1：编写动态库gn脚本test/examples/partA/feature1/BUILD.gn，示例如下：
+
+    ```
+    config("helloworld_lib_config") {
+     include_dirs = [ "include" ]
+    }
+    
+    ohos_shared_library("helloworld_lib") {
+      sources = [
+        "include/helloworld1.h",
+        "src/helloworld1.cpp",
+      ]
+      public_configs = [ ":helloworld_lib_config" ]
+      part_name = "partA"
+    }
+    ```
+
+    示例2：编写可执行文件gn脚本test/examples/partA/feature2/BUILD.gn，示例如下：
+
+    ```
+    ohos_executable("helloworld_bin") {
+      sources = [
+        "src/helloworld2.cpp"
+      ]
+      include_dirs = [ "include" ]
+      deps = [                                # 依赖组件内模块
+        "../feature1:helloworld_lib"
+      ]
+      external_deps = [ "partB:module1" ]     # （可选）如果有跨组件的依赖，格式为“组件名:模块名”
+      install_enable = true                   # 可执行程序缺省不安装，需要安装时需要指定
+      part_name = "partA"
+    }
+    ```
+
+    示例3：编写etc模块gn脚本test/examples/partA/feature3/BUILD.gn，示例如下：
+
+    ```
+    ohos_prebuilt_etc("feature3_etc") {
+      source = "src/config.conf"
+      relative_install_dir = "init"    #可选，模块安装相对路径，相对于默认安装路径；默认在/system/etc目录
+      part_name = "partA"
+    }
+    ```
+
+    示例4：在子系统的ohos.build中添加组件配置：test/examples/ohos.build。每个子系统有一个ohos.build配置文件，在子系统的根目录下。示例如下：
+
+    ```
+    "partA": {
+        "module_list": [
+          "//test/examples/partA/feature1:helloworld_lib",
+          "//test/examples/partA/feature2:helloworld_bin",
+          "//test/examples/partA/feature3:feature3_etc",
+        ],
+        "inner_kits": [
+    
+        ],
+        "system_kits": [
+    
+        ],
+        "test_list": [
+    
+        ]
+      }
+    ```
+
+    一个组件包含module\_list、inner\_kits、system\_kits、test\_list四个部分的声明，其中：
+
+    -   module\_list：组件所包含的模块列表；
+    -   inner\_kits：组件提供给其它组件调用的接口，其他组件的模块可以在external\_deps中添加依赖的模块；
+    -   system\_kits：组件提供给开发者开发应用的接口；
+    -   test\_list：组件中对应模块的测试用例；
+
+2.  将组件添加到产品配置中。
+
+    在产品的配置中添加组件，产品对应的配置文件：productdefine/common/products/\{product-name\}.json。
+
+    在产品配置文件中添加 "subsystem\_examples:partA"，表示该产品中会编译并打包partA到版本中。
+
+3.  编译。
+
+    以编译Hi3516DV300为例，编译命令如下：
+
+    ```
+    ./build.sh --product-name Hi3516DV300 --ccache
+    ```
+
+4.  编译输出。
+
+    编译所生成的文件都归档在out/ohos-arm-release/目录下，结果镜像输出在 out/ohos-arm-release/packages/phone/images/ 目录下。

+
+```
+SensorInfo *sensorInfo = (SensorInfo *)NULL;
+int32_t count = 0;
+int32_t ret = GetAllSensors(&sensorInfo, &count);
+```
+
+1.  创建的传感器用户
+
+```
+SensorUser sensorUser;
+sensorUser.callback = SensorDataCallbackImpl; //成员变量callback指向创建的回调方法
+```
+

+
+    在相应的业务逻辑里面调用ISysEventService::AddListener\(in SysEventRule\[\] rules, in ISysEventCallback callback\)接口。
+
+    实现对应的回调对象：

+## 使用场景<a name="section726685714018"></a>
+
+UI动画通过task处理机制每个tick调用一下用户设置的callback函数来实现，具体实现为AnimatorManager、Animator、AnimatorCallback三个类实现。
+
+-   AnimatorManager：AnimatorManager为单例，在Init函数执行时将自己注册到系统task回调函数中，系统task机制保证每个tick会调用一下AnimatorManager的callback函数，同时AnimatorManager用来管理Animator实例。
+-   Animator：Animator中可以设置动画相关的属性，包括动画的起止时间，动画开始和停止，动画状态的设置和获取等。
+-   AnimatorCallback：具体每一个tick动画所要做的内容在AnimatorCallback类中实现，开发者需要自己实现Callback方法，动画执行时在Callback实现相应功能。

+
+1.  实现AnimatorCallback的回调函数。
+
+    ```
+    class AnimatorCallbackDemo : public OHOS::AnimatorCallback {
+    public:
+        AnimatorCallbackDemo(int16_t startPos, int16_t endPos, uint16_t time)
+            : start_(startPos), end_(endPos), time_(time), curTime_(0) {}
+     
+        virtual void Callback(OHOS::UIView* view)
+        {
+            curTime_++;
+            int16_t pos = EasingEquation::CubicEaseIn(start_, end_, curTime_, time_);
+            view->Invalidate();
+            view->SetPosition(pos, view->GetY());
+            view->Invalidate();
+        }
+    protected:
+        int16_t start_;
+        int16_t end_;
+        uint16_t time_;
+        uint16_t curTime_;
+    };
+    ```
+
+2.  将AnimatorCallback添加到Animator中。
+
+    ```
+    UIImageView* image = new UIImageView();
+    image->SetSrc("..\\config\\images\\A021_001.bin");
+    image->SetPosition(0, 50);
+    AnimatorCallbackDemo* callback = new AnimatorCallbackDemo(0, 338, 60);
+    Animator* animator = new Animator(callback, image, 0, true);
+    ```
+
+3.  将Animator添加到AnimatorManager中。
+
+    ```
+    AnimatorManager::GetInstance()->Add(animator);
+    ```
+
+4.  点击下图下方的按钮，检查对应的动画运行效果。

+
+容器类组件，指能包含其它UI组件的组件，容器类组件继承于UIViewGroup（带Add方法），基于实际组件的使用场景，将需要增加其他子组件的组件，放置到容器类继承结构下。如UIAnalogClock内，通常会Add需要的计步信息，时分秒图标等。
+
+**图 1**  普通容器类组件结构<a name="fig1931013319293"></a>  
+![](figure/普通容器类组件结构.png "普通容器类组件结构")
+
+RootView、UIAbstractScroll、UIPicker组件从UIViewGroup继承，UIList、UIScrollView、UISwipeView组件从UIAbstractScroll继承。
+
+## UIViewGroup<a name="section145471898812"></a>
+
+## 使用场景<a name="section0916112362216"></a>
+
+UIViewGroup是容器类组件基类，实现增加、删除、插入等操作，通过增加方法可以添加子组件。普通容器类组件子组件需要设置位置信息，位置信息为相对父组件的相对坐标。组件树结构如下图：
+
+**图 2**  组件树结构示意图<a name="fig279970183012"></a>  
+![](figure/组件树结构示意图.png "组件树结构示意图")
+
+往根节点rootView里添加ViewGroup1容器组件和View1组件，往ViewGroup1容器组件里再添加View2组件和ViewGroup2容器组件，在View1之后添加View3组件。
+
+-   关于渲染：容器类组件在渲染时会遍历所有子组件OnDraw方法，以达到刷新所有组件的目的。
+-   关于坐标：子组件位置信息为相对父组件的相对坐标，系统在渲染时计算绝对坐标并显示。
+-   关于树结构遍历：UIViewGroup提供如下方法实现遍历、查找、管理组件树。

+布局类容器组件由视图基础类组成，通过直接设置视图位置，可以达到嵌套和重叠布局的目的；通过设置布局类型和边距达到规格化布局子组件的目的；通过调用相关接口可实现根据父组件及兄弟节点布局视图的目的。
+
+## UISwipeView<a name="section13631719181717"></a>
+
+## 使用场景<a name="section11299120102617"></a>
+
+UISwipeView继承UIViewGroup，除提供容器类组件Add、Remove、Insert等方法外还提供按页面滑动功能，滑动结束后当前页面居中对齐显示。该组件分为水平方向和垂直方向，通过Add方法添加的子组件会根据Add的顺序和UISwipeView方向自动水平对齐或则垂直对齐。

+
+1.  实现点击事件。
+
+    ```
+    class TestBtnOnClickListener : public OHOS::UIView::OnClickListener {
+        bool OnClick(UIView& view, const ClickEvent& event) override
+        {
+            int16_t width = view.GetWidth() + 10;
+            int16_t height = view.GetHeight() + 10;
+            view.Resize(width, height);
+            view.Invalidate();
+            return true;
+        }
+    };
+    ```
+
+2.  创建一个UIButton。
+
+    ```
+    UIButton* button = new UIButton();
+    button->SetPosition(50, 50);
+    button->SetWidth(100);
+    button->SetHeight(50);
+    ```
+
+3.  给UIButton注册点击事件回调。
+
+    ```
+    button->SetOnClickListener(new TestBtnOnClickListener());
+    ```
+
+4.  检查Button点击效果如下图所示，Button逐渐变大。

+
+-   [基本概念](#section175012297491)
+-   [运作机制](#section193961322175011)
+
+## 基本概念<a name="section175012297491"></a>
+
+相机是OpenHarmony多媒体进程提供的服务之一，提供了相机的录像、预览、拍照功能，支持多用户并发取流。
+
+在进行应用的开发前，开发者应了解以下基本概念：
+
+-   视频帧
+
+    视频流指的是将一系列图片数据按照固定时间间隔排列形成的数据流，每一张图片数据成为一帧，这样的一帧称为视频帧。
+
+-   帧速率\(FPS: Frames Per Second\)
+
+    视频播放每秒钟刷新图片的速度，或是视频每秒的帧数，帧速率越高，视频的观感越流畅。
+
+-   分辨率
+
+    每一帧的图片信息都是由像素点组成的，分辨率描述了一张图片中像素点的个数。例如1920\*1080\(1080P\)，是指图片宽1920像素，高1080像素。
+
+
+## 运作机制<a name="section193961322175011"></a>
+
+-   多媒体服务进程
+
+    多媒体服务作为系统服务，在系统启动时由Init进程拉起，并初始化和分配媒体硬件资源（内存/显示硬件/图像传感器/编解码器等）。初始化过程解析配置文件，确定了多媒体各个服务的能力和资源上限，通常由OEM厂商通过配置文件进行配置。相机服务在多媒体进程初始化时有以下配置项：
+
+    -   内存池：所有媒体服务依赖于内存池中的内存轮转运行
+    -   图像传感器：包括了传感器类型、分辨率、ISP等
+    -   图像处理器：分辨率、码率、图像翻转等
+    -   图像编码器：编码格式、码率、分辨率等
+
+
+-   关键类的解释
+
+    应用通过持有下面4个类，配置和使用Camera的功能，包括了Camera类和它的三个异步回调类，三类回调分别对应了不同类型的异步处理场景，详见[表1](#table486418149411)。

+-   流的传递
+
+    Surface是多媒体传递音视频的基本数据结构，Camera一般作为Surface中数据的生产者，在不同的场景下有特定的消费者。
+
+    相机的预览和录像输出均为视频流，拍照输出为图像帧，二者均通过Surface类进行传递。Surface类可以屏蔽进程内/跨进程的场景，进行多媒体信息流的传递。
+
+    以录像为例，用户首先创建Recorder实例，并从Recorder中获取对应Surface，再将此Surface传递给Camera实例，此时Camera将作为生产者向Surface注入视频流，而Recorder作为消费者从Surface中取出视频流进行保存，用户的行为类似桥接，把二者通过Surface连接起来。
+
+    类似的，用户也可以自行创建Surface传递给Camera实例，并实现消费者逻辑（例如通过网络传输视频流，或是将拍照的帧数据保存成图片文件）。
+
+    图形图像模块也通过Surface从Camera获取流资源，具体步骤详见[图形图像开发指导](subsys-graphics-overview.md)。
+
+-   相机运行流程
+    1.  Camera创建流程
+
+        本进程通过CameraManager创建Camera实例，并从服务端绑定camera设备，创建成功后异步通知developer。类之间的时序图如下：

+
+
+    1.  Camera录像/预览流程
+
+        开发者首先通过CameraKit创建Camera，然后FrameConfig类对录像或者预览帧属性进行配置。录像/预览时序如下：

+
+## 开发步骤<a name="section138543918214"></a>
+
+1.  <a name="li378084192111"></a>实现设备状态回调的派生类，用户在设备状态发生变更（如新插入相机设备/相机掉线）时，自定义操作。
+
+    ```
+    class SampleCameraDeviceCallback : public CameraDeviceCallback {
+        void OnCameraStatus(std::string cameraId, int32_t status) override
+        {
+            //do something when camera is available/unavailable
+        }
+    };
+    ```
+
+2.  <a name="li8716104682913"></a>实现帧事件回调的派生类，这里在拿到帧数据以后将其转存为文件。
+
+    ```
+    static void SampleSaveCapture(const char *p, uint32_t size)
+    {
+        cout << "Start saving picture" << endl;
+        struct timeval tv;
+        gettimeofday(&tv, NULL);
+        struct tm *ltm = localtime(&tv.tv_sec);
+        if (ltm != nullptr) {
+            ostringstream ss("Capture_");
+            ss << "Capture" << ltm->tm_hour << "-" << ltm->tm_min << "-" << ltm->tm_sec << ".jpg";
+    
+            ofstream pic("/sdcard/" + ss.str(), ofstream::out | ofstream::trunc);
+            cout << "write " << size << " bytes" << endl;
+            pic.write(p, size);
+            cout << "Saving picture end" << endl;
+        }
+    }
+    
+    class TestFrameStateCallback : public FrameStateCallback {
+        void OnFrameFinished(Camera &camera, FrameConfig &fc, FrameResult &result) override
+        {
+            cout << "Receive frame complete inform." << endl;
+            if (fc.GetFrameConfigType() == FRAME_CONFIG_CAPTURE) {
+                cout << "Capture frame received." << endl;
+                list<Surface *> surfaceList = fc.GetSurfaces();
+                for (Surface *surface : surfaceList) {
+                    SurfaceBuffer *buffer = surface->AcquireBuffer();
+                    if (buffer != nullptr) {
+                        char *virtAddr = static_cast<char *>(buffer->GetVirAddr());
+                        if (virtAddr != nullptr) {
+                            SampleSaveCapture(virtAddr, buffer->GetSize());
+                        }
+                        surface->ReleaseBuffer(buffer);
+                    }
+                    delete surface;
+                }
+                delete &fc;
+            }
+        }
+    };
+    ```
+
+3.  <a name="li6671035102514"></a>实现相机状态回调的派生类，当相机状态发生变化（配置成功/失败，创建成功/失败\)时，自定义操作。
+
+    ```
+    class SampleCameraStateMng : public CameraStateCallback {
+    public:
+        SampleCameraStateMng() = delete;
+        SampleCameraStateMng(EventHandler &eventHdlr) : eventHdlr_(eventHdlr) {}
+        ~SampleCameraStateMng()
+        {
+            if (recordFd_ != -1) {
+                close(recordFd_);
+            }
+        }
+        void OnCreated(Camera &c) override
+        {
+            cout << "Sample recv OnCreate camera." << endl;
+            auto config = CameraConfig::CreateCameraConfig();
+            config->SetFrameStateCallback(&fsCb_, &eventHdlr_);
+            c.Configure(*config);
+            cam_ = &c;
+        }
+        void OnCreateFailed(const std::string cameraId, int32_t errorCode) override {}
+        void OnReleased(Camera &c) override {}
+    };
+    ```
+
+4.  创建CameraKit，用于创建和获取camera信息。
+
+    ```
+    CameraKit *camKit = CameraKit::GetInstance();
+    list<string> camList = camKit->GetCameraIds();
+    string camId;
+    for (auto &cam : camList) {
+        cout << "camera name:" << cam << endl;
+        const CameraAbility *ability = camKit->GetCameraAbility(cam);
+        /* find camera which fits user's ability */
+        list<CameraPicSize> sizeList = ability->GetSupportedSizes(0);
+        if (find(sizeList.begin(), sizeList.end(), CAM_PIC_1080P) != sizeList.end()) {
+            camId = cam;
+            break;
+        }
+    }
+    ```
+
+5.  创建Camera实例。
+
+    ```
+    EventHandler eventHdlr; // Create a thread to handle callback events
+    SampleCameraStateMng CamStateMng(eventHdlr);
+    
+    camKit->CreateCamera(camId, CamStateMng, eventHdlr);
+    ```
+
+6.  根据[步骤1](#li378084192111)、[步骤2](#li8716104682913)、[步骤3](#li6671035102514)中的回调设计，camera实例创建成功后会进行配置操作，主流程中app需要设计同步机制。
+
+    ```
+    void OnCreated(Camera &c) override
+    {
+        cout << "Sample recv OnCreate camera." << endl;
+        auto config = CameraConfig::CreateCameraConfig();
+        config->SetFrameStateCallback(&fsCb_, &eventHdlr_);
+        c.Configure(*config);
+        cam_ = &c;
+    }
+    
+    void Capture()
+    {
+        if (cam_ == nullptr) {
+            cout << "Camera is not ready." << endl;
+            return;
+        }
+        FrameConfig *fc = new FrameConfig(FRAME_CONFIG_CAPTURE);
+        Surface *surface = Surface::CreateSurface();
+        if (surface == nullptr) {
+            delete fc;
+            return;
+        }
+        surface->SetWidthAndHeight(1920, 1080); /* 1920:width,1080:height */
+        fc->AddSurface(*surface);
+        cam_->TriggerSingleCapture(*fc);
+    }
+    ```

+
+升级包不是按照上文“生成公私钥对”和“生成升级包”章节制作的，是通过其它方式制作的。
+

+
+1.  应用侧通过下载，获取当前设备升级包后，调用HotaInit接口初始化。
+2.  使用HotaSetPackageType接口设置NOT\_USE\_DEFAULT\_PKG，使用"定制"流程。
+3.  调用HotaWrite接口传入升级包数据流，写入设备。
+4.  写入完成后，调用HotaRead接口读取数据，厂商可以自行校验升级包。
+5.  调用HotaSetBootSettings设置启动标记，在重启后需要进入uboot模式时使用（可选）。
+6.  调用HotaRestart接口，进行重启。
+
+    升级过程中，使用HotaCancel接口可以取消升级。

+-   [基本概念](#section175012297491)
+-   [约束与限制](#section2029921310472)
+
+OpenHarmony安全子系统目前提供给开发者的安全能力主要包含应用可信、权限管理、设备可信。涉及以下几个模块：
+
+-   应用验签
+
+    为了确保应用内容的完整性，系统通过应用签名和Profile对应用的来源进行管控，同时对于调试应用，还可通过验签接口验证应用和设备的UDID是否匹配，确保应用安装在了正确的设备上。
+
+-   应用权限管理
+
+    应用权限是管理应用访问系统资源和使用系统能力的一种通用方式，应用在开发阶段需要在profile.json中指明此应用在运行过程中可能会调用哪些权限，其中静态权限表示只需要在安装阶段注册就可以，而动态权限一般表示涉及到敏感信息，所以需要用户进行动态授权。
+
+-   IPC通信鉴权
+
+    系统服务通过IPC暴露接口给其他进程访问，这些接口需要配置相应的访问策略，当其他进程访问这些接口时，将会触发IPC通信鉴权机制校验访问进程是否拥有权限访问该接口，若无权限，则拒绝访问该接口。
+
+-   可信设备群组管理
+
+    提供基于群组概念的同华为账号群组、点对点群组（如二维码、碰一碰等）的设备安全可信关系的创建和查询，分布式应用可基于该能力进行设备间的可信认证，然后向分布式软总线请求设备间安全会话。
+
+
+## 基本概念<a name="section175012297491"></a>
+
+在进行依赖验签组件的应用开发前，开发者应了解以下基本概念：
+
+-   Samgr
+
+    Samgr\(System Ability Manager\)系统能力管理，在OpenHarmony上作为一个管理系统能力的模块，详见系统服务框架子系统。
+
+
+-   BMS
+
+    BMS\(Bundle Manager Service\)包管理管理，在OpenHarmony上主要负责应用的安装、卸载和数据管理。
+
+
+-   描述文件
+
+    本文中的描述文件，指HarmonyAppProvision，简称profile。HarmonyAppProvision采用json文件格式进行描述。
+
+
+-   叶子证书
+
+    最终用于为整包或profile签名的证书称为叶子证书，位于数字证书链的最末端。
+
+
+-   调试应用
+
+    指开发者从应用市场申请调试证书与调试描述文件，并以此签名的hap包。
+
+
+-   待上架应用
+
+    指开发者从应用市场申请发布证书与发布描述文件，以此签名，未通过应用市场正式发布的hap包。
+
+
+-   发布应用
+
+    指开发者从应用市场申请发布证书与发布描述文件，以此签名的hap包，上传至应用市场，并由应用市场正式发布的hap包。
+
+
+-   OpenHarmony自签名应用
+
+    当开发者自行编译OpenHarmony系统应用后，采用原应用描述文件，以及公开的OpenHarmony公私钥对和证书进行自签名产生的hap包。
+
+
+## 约束与限制<a name="section2029921310472"></a>
+
+-   仅支持以下三类应用的验签：应用市场调试应用、应用市场发布应用、OpenHarmony自签名应用的验签。
+-   若对应用市场调试应用验签，则本机UDID需要在描述文件包含的UDID列表中。
+-   待上架应用无法验签通过。
+-   验签组件提供的接口都位于security\_interfaces\_innerkits\_app\_verify仓[app\_verify\_pub.h](https://gitee.com/fork_ohos_wj/security_interfaces_innerkits_app_verify/blob/master/app_verify_pub.h)中，仅支持系统应用开发者调用。
+-   可信设备群组管理接口，目前只对系统签名权限才可以使用。

+
+由于OpenHarmony允许安装三方应用，所以需要对三方应用的敏感权限调用进行管控，具体实现是应用在开发阶段就需要在profile.json中指明此应用在运行过程中可能会调用哪些敏感权限，这些权限包括静态权限和动态权限，静态权限表示只需要在安装阶段注册就可以，而动态权限一般表示获取用户的敏感信息，所以需要在运行时让用户确认才可以调用，授权方式包括系统设置应用手动授权等。除了运行时对应用调用敏感权限进行管控外，还需要利用应用签名管控手段确保应用安装包已经被设备厂商进行了确认。

+
+应用权限是软件用来访问系统资源和使用系统能力的一种通行方式。在涉及用户隐私相关功能和数据的场景，例如：访问个人设备的硬件特性，如摄像头、麦克风，以及读写媒体文件等，OpenHarmony通过应用权限管理组件来保护这些数据以及能力。
+
+在系统应用开发过程中，如果应用要使用敏感权限，开发者可以调用应用权限管理组件接口检查待访问权限是否被授权，如果未授权，操作不允许。

+## 开发步骤<a name="section022611498210"></a>
+
+本部分以包管理器的应用权限开发为例进行讲解。开发过程中，首先需要明确涉及的敏感权限，并在config.json中声明该权限，在安装应用程序时，包管理器会调用应用权限管理组件的接口检查该权限是否被授予，若授予，安装流程正常进行，否则安装失败。
+
+1.  在开发过程中，包管理器明确需要安装应用的权限（ohos.permission.INSTALL\_BUNDLE），并在config.json中声明该权限；
+
+    ```
+    {
+      ...
+      "module": {
+          "package": "com.huawei.kitframework",
+          "deviceType": [
+              "phone", "tv","tablet", "pc","car","smartWatch","sportsWatch","smartCamera", "smartVision"
+          ],
+          "reqPermissions": [{
+            // 声明需要的权限：安装应用程序的权限名
+            "name": "ohos.permission.INSTALL_BUNDLE",   
+            "reason": "install bundle",
+            "usedScene": {
+              "ability": [
+                "KitFramework"
+                ],
+              "when": "always"
+            }
+          },
+          {
+            "name": "ohos.permission.LISTEN_BUNDLE_CHANGE",
+            "reason": "install bundle",
+            "usedScene": {
+              "ability": [
+                "KitFramework"
+                ],
+              "when": "always"
+            }
+          },
+          {
+            "name": "ohos.permission.GET_BUNDLE_INFO",
+            "reason": "install bundle",
+            "usedScene": {
+              "ability": [
+                "KitFramework"
+                ],
+              "when": "always"
+            }
+          }
+          ],
+        ...
+    }
+    ```
+
+2.  当包管理器开发应用安装功能接口时，会调用权限管理相关接口检查自身是否具有安装应用程序的权限，例如：以安装应用的权限名"ohos.permission.INSTALL\_BUNDLE"作为入参，调用CheckPermission接口检查包管理器是否具有安装应用的权限，如果有权限，安装流程继续执行，否则返回安装失败；
+
+    ```
+    constexpr static char PERMISSION_INSTALL_BUNDLE[] = "ohos.permission.INSTALL_BUNDLE";
+    
+    bool Install(const char *hapPath, const InstallParam *installParam, InstallerCallback installerCallback)
+    {
+        if ((hapPath == nullptr) || (installerCallback == nullptr) || (installParam == nullptr)) {
+            HILOG_ERROR(HILOG_MODULE_APP, "BundleManager install failed due to nullptr parameters");
+            return false;
+        }
+        // 检查ohos.permission.INSTALL_BUNDLE权限是否被授予
+        if (CheckPermission(0, static_cast<const char *>(PERMISSION_INSTALL_BUNDLE)) != GRANTED) {
+            HILOG_ERROR(HILOG_MODULE_APP, "BundleManager install failed due to permission denied");
+            return false;  // 返回安装失败
+        }
+        // 安装流程
+        ...
+    }
+    ```

+## 场景介绍<a name="section18502174174019"></a>
+
+当需要验证调试应用、发布应用，OpenHarmony自签名应用的完整性是否被破坏时，可以调用验签组件的接口进行验证。如有需要还可通过验签接口获取部分描述文件信息，如appid。对于调试应用，还可通过验签接口验证应用和设备的UDID是否匹配，确保应用安装在了正确的设备上。
+
+## 验签流程<a name="section554632717226"></a>
+
+未经签名的Hap包的压缩方式是ZIP格式，简单分为文件块，中心目录（Central directory）块，中心目录结尾（EOCD，End of central directory record）块。
+
+经过签名的Hap包，在文件块，和中心目录块之间，插入了签名块。签名块由文件签名数据块（data sign block）、描述文件签名数据块（profile sign block）和签名头（sign head）组成，如下图所示。
+
+**图 1**  经过签名的Hap包结构<a name="fig699855043"></a>  
+
+
+![](figure/安全子系统.png)
+
+整个验签流程，主要分为三部分：整包验签、描述文件签名块验签，以及描述文件内容校验。
+
+**整包验签**
+
+用设备的预置根证书，通过证书链来证明叶子证书本身是可信的，然后用叶子证书的公钥解密出的摘要证明整包是未篡改的。
+
+具体操作步骤如下：
+
+1.  对文件签名数据块中的证书链进行校验，确定其叶子证书是可信的。
+2.  用叶子证书中的公钥对文件签名块进行验签，证明其未被篡改。
+3.  计算并合并文件块，中心目录块和中心目录结尾块的摘要。然后将计算结果，再与签名块中的描述文件签名块的摘要合并，将最终合并的摘要与文件签名块中包含的摘要对比，如果两者相等，则整包验签通过。
+
+**描述文件签名块验签**
+
+首先判断文件签名的签发单位，如果是应用市场签发的发布应用，则无需对描述文件进行验签，直接信任，否则要对其验签。先取出整个描述文件签名块，然后验证证书链，最后用叶子证书对描述文件数据块验签，证明其未被篡改。
+
+**描述文件内容校验**
+
+取出描述文件，并对其内容进行合法性检查。其中若hap包为调试应用，则会比对本机UDID与描述文件中包含的UDID列表，如果本机UDID在描述文件的UDID列表中包含，则验证通过。比较描述文件中包含的证书（如果是应用市场发布应用或OpenHarmony自签名则无需比较），和整包校验时使用的叶子证书，如果相同，认为整个验签流程完成。

+1.  材料备齐。
+
+    生成自签名应用需要的材料有：签名工具、系统应用hap包、系统应用profile文件\(\*.p7b\)、签名证书\(\*.cer\)、签名公私钥对\(\*.jks\)。
+
+2.  将所有材料放在同一个目录下，打开shell。
+3.  根据应用、描述文件的实际名称修改指令，并在shell中输入，完成签名。
+
+    ```
+    java -jar hapsigntoolv2.jar sign -mode localjks -privatekey "OpenHarmony Software Signature" -inputFile camera.hap -outputFile signed_camera.hap -signAlg SHA256withECDSA -keystore OpenHarmony.jks -keystorepasswd 123456 -keyaliaspasswd 123456 -profile camera_release.p7b -certpath OpenHarmony.cer -profileSigned 1
+    ```
+
+    关键字段说明：
+
+    -jar：签名工具，[hapsigntool](https://repo.huaweicloud.com/harmonyos/develop_tools/hapsigntoolv2.jar)
+
+    -mode：本地签名标记位，固定为localjks
+
+    -privatekey：密钥对别名，签名公私钥对的别名为OpenHarmony Software Signature
+
+    -inputFile：待签名应用，通过编译产生
+
+    -outputFile：签名后应用，最终输出
+
+    -signAlg：签名算法，当前固定为SHA256withECDSA
+
+    -keystore：公私钥对，使用签名公私钥对，位于开源库security\_services\_app\_verify仓中OpenHarmonyCer目录下，[OpenHarmony.jks](https://gitee.com/openharmony/security_appverify/blob/master/interfaces/innerkits/appverify_lite/OpenHarmonyCer/OpenHarmony.jks)。默认密码为123456 ，用户可采用工具\(例如keytool\)更改默认密码
+
+    -keystorepasswd：公私钥对密码，默认签名公私钥对密码为123456
+
+    -keyaliaspasswd：公私钥对别名密码，默认签名公私钥对别名密码为123456
+
+    -profile：描述文件，应用的描述文件位于对应源代码目录中
+
+    -certpath：使用签名证书，位于开源库security\_services\_app\_verify仓中OpenHarmonyCer目录下，[OpenHarmony.cer](https://gitee.com/openharmony/security_appverify/blob/master/interfaces/innerkits/appverify_lite/OpenHarmonyCer/OpenHarmony.cer)
+
+    -profileSigned：签名块中是否包含描述文件\(profile\)。固定为1（包含）

+### 开发示例<a name="section174318361353"></a>
+
+以应用管理框架组件在应用安装时进行验签的实际调用为例：
+
+```
+uint8_t HapSignVerify::VerifySignature(const std::string &hapFilepath, SignatureInfo &signatureInfo)
+{
+	bool mode = ManagerService::GetInstance().IsDebugMode();
+	HILOG_INFO(HILOG_MODULE_APP, "current mode is %d!", mode);
+        // 定义结果结构体
+	VerifyResult verifyResult = {0};
+        // 输入待验签文件路径进行验签
+	int32_t ret = APPVERI_AppVerify(hapFilepath.c_str(), &verifyResult); 
+	uint8_t errorCode = SwitchErrorCode(ret);
+	if (errorCode != ERR_OK) {
+		return errorCode;
+	}
+        // 从结果结构体中获取appid
+	signatureInfo.appId = verifyResult.profile.appid; 
+        // 从结果结构体中获取描述文件中书写的应用名
+	signatureInfo.provisionBundleName = verifyResult.profile.bundleInfo.bundleName; 
+	int32_t restricNum = verifyResult.profile.permission.restricNum;
+	for (int32_t i = 0; i < restricNum; i++) {
+		signatureInfo.restrictedPermissions.emplace_back((verifyResult.profile.permission.restricPermission)[i]);
+	}
+        // 释放结果结构体中申请的内存
+	APPVERI_FreeVerifyRst(&verifyResult); 
+	return ERR_OK;
+}
+```
+
+## 开发步骤（场景二）<a name="section81272563427"></a>
+
+### 验签指导<a name="section07028210442"></a>
+
+对采用基于测试根密钥证书签名的应用的校验。
+
+1.  调用APPVERI\_SetDebugMode\(true\)开启测试模式；
+
+    ```
+    	ManagerService::SetDebugMode(true);
+    ...
+    uint8_t ManagerService::SetDebugMode(bool enable)
+    {
+    	int32_t ret = APPVERI_SetDebugMode(enable);
+    	if (ret < 0) {
+    		HILOG_ERROR(HILOG_MODULE_APP, "set signature debug mode failed");
+    		return ERR_APPEXECFWK_SET_DEBUG_MODE_ERROR;
+    	}
+    	isDebugMode_ = enable;
+    	HILOG_INFO(HILOG_MODULE_APP, "current sign debug mode is %d", isDebugMode_);
+    	return ERR_OK;
+    }
+    ```
+
+2.  同场景一中步骤一至四，定义结构体，校验、释放结构体；
+3.  调用APPVERI\_SetDebugMode\(false\)关闭测试模式。
+
+    ```
+            ManagerService::SetDebugMode(false);
+    ```
+
+
+### 开发示例<a name="section1930711345445"></a>
+
+完整开发示例如下（在场景一代码示例的基础上进行补充）：
+
+```
+uint8_t ManagerService::SetDebugMode(bool enable)
+{
+	int32_t ret = APPVERI_SetDebugMode(enable);
+	if (ret < 0) {
+		HILOG_ERROR(HILOG_MODULE_APP, "set signature debug mode failed");
+		return ERR_APPEXECFWK_SET_DEBUG_MODE_ERROR;
+	}
+	isDebugMode_ = enable;
+	HILOG_INFO(HILOG_MODULE_APP, "current sign debug mode is %d", isDebugMode_);
+	return ERR_OK;
+}
+uint8_t HapSignVerify::VerifySignature(const std::string &hapFilepath, SignatureInfo &signatureInfo)
+{
+        // 开启支持测试服务器签名应用验证
+        ManagerService::SetDebugMode(true); 
+	bool mode = ManagerService::GetInstance().IsDebugMode();
+	HILOG_INFO(HILOG_MODULE_APP, "current mode is %d!", mode);
+        // 定义结果结构体
+	VerifyResult verifyResult = {0}; 
+        // 输入待验签文件路径进行验签
+	int32_t ret = APPVERI_AppVerify(hapFilepath.c_str(), &verifyResult); 
+	uint8_t errorCode = SwitchErrorCode(ret);
+	if (errorCode != ERR_OK) {
+		return errorCode;
+	}
+        // 从结果结构体中获取appid
+	signatureInfo.appId = verifyResult.profile.appid; 
+        // 从结果结构体中获取描述文件中书写的应用名
+	signatureInfo.provisionBundleName = verifyResult.profile.bundleInfo.bundleName; 
+	int32_t restricNum = verifyResult.profile.permission.restricNum;
+	for (int32_t i = 0; i < restricNum; i++) {
+		signatureInfo.restrictedPermissions.emplace_back((verifyResult.profile.permission.restricPermission)[i]);
+	}
+        // 释放结果结构体中申请的内存
+        APPVERI_FreeVerifyRst(&verifyResult); 
+        // 关闭支持测试服务器签名应用验证
+        ManagerService::SetDebugMode(false); 
+	return ERR_OK;
+}
+```
+
+## 调测验证<a name="section427316292411"></a>
+
+1.  选取一个在OpenHarmony上能够正常安装的应用A。
+2.  根据开发指导开发。
+3.  对应用A，采用自开发程序进行验签，验签通过，能获取到appid。即为开发成功。

+## 概述<a name="section12403172115920"></a>
+
+### 基本概念<a name="section53632272090"></a>
+
+测试子系统提供基于python开发的一键式的开发者自测试平台，支持跨平台使用以及三方测试框架拓展，主要包括测试用例编译、测试用例管理、测试用例调度分发、测试用例执行、测试结果收集、测试报告生成、测试用例模板、测试环境管理等模块。
+
+在测试子系统开发前，开发者应先了解以下概念：
+
+-   测试用例编译
+
+    支持将测试用例源代码编译成可在被测设备侧执行的二进制文件。
+
+-   测试用例调度分发
+
+    支持将测试用例通过网口通道或者串口通道分发到不同的被测设备上，并且为每一个测试用例分配特定的测试用例执行器。
+
+-   测试用例执行器
+
+    负责测试用例的预处理，用例执行，结果记录等执行逻辑。
+
+-   测试用例模板
+
+    定义了测试用例以及用例编译配置GN文件的统一格式。
+
+-   测试平台kit
+
+    测试平台运行过程中公共方法，如提供测试用例目录向被测设备挂载文件系统，测试用例推送到被测设备，或者从被测设备获取测试结果等操作。
+
+-   测试报告生成
+
+    定义开发者自测试报告模板，生成web测试报告。
+
+-   测试环境管理
+
+    支持通过USB、串口等方式管理被测设备，功能包括设备发现，设备状态查询等。
+
+
+### 运作机制<a name="section2394431106"></a>
+
+-   测试平台架构图如下：
+
+**图 1**  测试平台架构<a name="fig418674910399"></a>  
+![](figure/测试平台架构.png "测试平台架构")
+
+-   测试平台运行时序图如下：
+
+**图 2**  测试平台运行时序<a name="fig107203017407"></a>  
+![](figure/测试平台运行时序.png "测试平台运行时序")
+
+-   测试平台运行原理
+
+测试平台通过shell脚本启动，以命令行方式支持一系列的测试指令执行，通过命令行输出测试结果。
+
+## 约束与限制<a name="section2029921310472"></a>
+
+-   功能使用范围：开发自测试平台仅支持代码级的测试用例开发和验证，如单元测试，模块测试。
+-   规格限制：当前测试框架的适用范围仅支持白盒测试。
+-   操作限制：一台测试设备上仅支持启动单个测试平台。

+### 开发步骤<a name="section53541946111218"></a>
+
+1.  按照开发者测试用例目录规划定义测试套文件，需要继承testing::Test类，命名以被测特性+Test命名，示例代码路径：test/developertest/examples/lite/cxx\_demo/test/unittest/common/calc\_subtraction\_test.cpp
+
+    ```

+    
+    class CalcSubtractionTest : public testing::Test {
+    public:
+        static void SetUpTestCase(void);
+        static void TearDownTestCase(void);
+        void SetUp();
+        void TearDown();
+    };
+    ```

+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >测试用例规范
+    >-   命名规范
+    >    测试用例源文件名称和测试套内容保持一致，测试套与用例之间关系1:N，测试套与测试源文件之间关系1:1，每个源文件全局唯一，格式：\[特性\]\_\[功能\]\_\[子功能1\]\_\[子功能1.1\]，子功能支持向下细分。
+    >    文件命名采用全小写+下划线方式命名，以test结尾，如demo用例：developertest/examples/lite/cxx\_demo

+    >    详见测试demo用例：developertest/examples/lite/cxx\_demo/test/unittest/common/calc\_subtraction\_test.cpp
+
+2.  实现测试套执行过程需要的预处理操作和后处理操作，即实现SetUp和TearDown方法。
+
+    ```
+    void CalcSubtractionTest::SetUpTestCase(void)
+    {
+        // step 1: input testsuite setup step
+    }
+    
+    void CalcSubtractionTest::TearDownTestCase(void)
+    {
+        // step 2: input testsuite teardown step
+    }
+    
+    void CalcSubtractionTest::SetUp(void)
+    {
+        // step 3: input testcase setup step
+    }
+    
+    void CalcSubtractionTest::TearDown(void)
+    {
+        // step 4: input testcase teardown step
+    }
+    ```
+
+3.  针对被测对象的特性编写测试用例，以使用HWTEST\_F为例说明。
+
+    ```
+    /**
+     * @tc.name: integer_sub_001
+     * @tc.desc: Test Calculator
+     * @tc.type: FUNC
+     * @tc.require: AR00000000 SR00000000
+     */
+    HWTEST_F(CalcSubtractionTest, integer_sub_001, TestSize.Level1)
+    {
+        EXPECT_EQ(0, Subtraction(1, 0));
+    }
+    ```
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >-   @tc.name：用例名称，对测试目的简要描述。
+    >-   @tc.desc：描述用例详细描述，包括测试目的、测试步骤、期望结果等。

+
+4.  编写用例编译GN文件，其中包括定义用例编译目标，添加编译配置依赖，源文件等，举例说明：
+
+    示例文件路径：test/developertest/examples/lite/cxx\_demo/test/unittest/common/BUILD.gn）。
+
+    ```
+    import("//build/lite/config/test.gni")
+    
+    unittest("CalcSubTest") {
+        output_extension = "bin"
+        sources = [
+            "calc_subtraction_test.cpp"
+        ]
+        include_dirs = []
+        deps = []
+    }
+    ```
+
+5.  将用例编译目标添加到子系统编译配置中，保证用例随版本一起编译，举例说明：
+    1.  支持hdc连接的设备，编译配置示例路径：test/developertest/examples/ohos.build。
+
+        ```
+        {
+          "subsystem": "subsystem_examples",
+          "parts": {
+            "subsystem_examples": {
+              "module_list": [
+                "//test/developertest/examples/detector:detector",
+                ... ...
+              ],
+              "test_list": [
+                "//test/developertest/examples/detector/test:unittest",
+                ... ...
+              ]
+            },
+            ... ...
+        }
+        ```
+
+    2.  仅支持串口的设备，编译配置示例路径：test/developertest/examples/lite/BUILD.gn。
+
+        ```
+        import("//build/lite/config/test.gni")
+        
+        subsystem_test("test") {
+            test_components = []
+            if(ohos_kernel_type == "liteos_riscv") {
+                features += [
+                ]
+            }else if(ohos_kernel_type == "liteos_a") {
+                test_components += [
+                    "//test/developertest/examples/lite/cxx_demo/test/unittest/common:CalcSubTest"
+                ]
+            }
+        }
+        ```
+
+
+6.  编写测试用例资源配置，当测试用例需要使用静态测试资源文件时使用该配置。
+    1.  在部件或者模块的test目录下创建resource目录。
+    2.  在resource目录下创建形态目录，如phone。
+    3.  在设备形态目录下创建一个以模块名命名的文件夹，如testmodule。
+    4.  在模块目录下创建一个ohos\_test.xml文件，文件内容格式如下:
+
+        ```
+        <?xml version="1.0" encoding="UTF-8"?>
+        <configuration ver="2.0">
+            <target name="DetectorFileTest">
+                <preparer>
+                    <option name="push" value="test.txt -> /data/test/resource" src="res"/>
+                </preparer>
+            </target>
+        </configuration>
+        ```
+
+    5.  在测试用例的编译配置文件中定义resource\_config\_file，用来指定对应的资源文件ohos\_test.xml。
+
+        >![](../public_sys-resources/icon-note.gif) **说明：** 
+        >如上资源文件功能：将resource目录下的test.txt文件通过hdc push命令推送到被测设备的/data/test/resource目录下。
+
+
+7.  以上步骤完成即完成测试用例编写，即可执行测试用例。
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >-   支持hdc连接的设备，测试用例支持单独编译。
+    >-   仅支持串口连接的设备，在代码根路径下执行编译debug版本的命令，即可编译测试用例。
+    >    测试用例用例的执行详见[测试平台使用](#section76401945124810)。
+
+
+## 开发实例<a name="section7477121918136"></a>
+
+测试子系统代码仓提供了完整demo用例，demo用例路径：test/developertest/examples/。以一个减法运算方法编写测试用例举例说明：
+
+-   被测代码如下：
+
+    ```
+    static int Subtraction(int a, int b)
+    {
+        return a - b;
+    }
+    ```
+
+-   测试用例代码如下：
+
+    ```
+    /**
+     * @tc.name: integer_sub_002
+     * @tc.desc: Verify the Subtraction function.
+     * @tc.type: FUNC
+     * @tc.require: AR00000000 SR00000000
+     */
+    HWTEST_F(CalcSubtractionTest, integer_sub_002, TestSize.Level1)
+    {
+        EXPECT_EQ(1, Subtraction(2, 1));
+    }
+    ```
+
+
+## 测试平台使用<a name="section76401945124810"></a>
+
+1.  （可选）安装xdevice组件。安装xdevice后，xdevice组件可以作为python的扩展包使用。
+
+    打开xdevice安装目录：test/xdevice，执行如下命令：
+
+    ```
+    python setup.py install
+    ```
+
+    安装成功提示如下：
+
+    ```
+    ... ...

+            <version>false</version>
+            <testcase>true</testcase>
+            ... ...

+        </device>
+        ```
+
+
+3.  （可选）修改developertest组件配置。如果测试用例已完成编译，可以直接指定测试用例的编译输出路径，测试平台执行用例时即不会重新编译测试用例。
+
+    配置文件：config/user\_config.xml
+
+    1.  \[test\_cases\]    \# 指定测试用例的输出路径，编译输出目录，例如：
+
+        ```

+            <host_dir>D:\nfs</host_dir>
+            <board_dir>user</board_dir>
+        </NFS>
+        ```
+
+
+4.  （可选）测试环境准备。当被测设备仅支持串口时，需要检查。
+    -   系统镜像与文件系统已烧录进开发板，开发板上系统正常运行，在系统模式下，如使用shell登录时，设备提示符是“OHOS\#”。
+    -   开发主机和开发板串口连接正常，网口连接正常。
+    -   开发主机IP与开发板IP处在同一小网网段，相互可以ping通。
+    -   开发主机侧创建空目录用于开发板通过NFS挂载测试用例，并且NFS服务启动正常。
+
+5.  （必选）启动测试平台，执行测试用例。
+    -   启动测试框架，打开test/developertest目录，执行启动脚本。
+        1.  Windows环境启动测试框架，执行如下脚本：
+
+            ```
+            start.bat
+            ```
+
+        2.  Linux环境启动测试框架。
+
+            ```
+            ./start.sh
+            ```
+
+
+    -   设备形态选择。
+
+        根据实际的开发板选择，设备形态配置：developertest/config/framework\_config.xml。
+
+    -   执行测试指令。
+        1.  查询测试用例支持的子系统，模块，产品形态以及测试类型，使用show命令，示例如下：
+
+            ```
+            usage: 
+                show productlist      Querying Supported Product Forms
+                show typelist         Querying the Supported Test Type
+                show subsystemlist    Querying Supported Subsystems
+                show modulelist       Querying Supported Modules
+            ```
+
+        2.  执行测试指令，其中-t为必选，-ss和-tm为可选字段，示例如下：
+
+            ```
+            run -t ut -ss subsystem_examples -tm calculator
+            ```
+
+        3.  参数说明：指定参数可以执行特定特性、模块对应的测试套。
+
+            ```
+            usage: run [-h] [-p PRODUCTFORM] [-t [TESTTYPE [TESTTYPE ...]]]
+                [-ss SUBSYSTEM] [-tm TESTMODULE] [-ts TESTSUIT]
+                [-tc TESTCASE] [-tl TESTLEVEL] 
+            
+            optional arguments:
+                -h, --help            show this help message and exit
+                -p PRODUCTFORM, --productform PRODUCTFORM    Specified product form
+                -t [TESTTYPE [TESTTYPE ...]], --testtype [TESTTYPE [TESTTYPE ...]]
+                    Specify test type(UT,MST,ST,PERF,ALL)
+                -ss SUBSYSTEM, --subsystem SUBSYSTEM    Specify test subsystem
+                -tm TESTMODULE, --testmodule TESTMODULE    Specified test module
+                -ts TESTSUIT, --testsuite TESTSUIT    Specify test suite

+                -tl TESTLEVEL, --testlevel TESTLEVEL    Specify test level
+            ```
+
+
+    -   测试框架帮助。
+
+        帮助指令，用于查询测试平台支持哪些测试指令，如下：
+
+        ```
+        help
+        ```
+
+    -   退出自测试平台。
+
+        退出自测试平台，使用如下命令退出测试平台，如下：
+
+        ```
+        quit
+        ```
+
+
+6.  （必选）查看测试结果与日志，通过在测试平台中执行测试指令，即可在developertest/reports目录下生成测试日志和测试报告。
+    -   测试用例的结果会直接显示在控制台上，执行一次的测试结果根路径如下：
+
+        ```
+        reports/xxxx-xx-xx-xx-xx-xx
+        ```
+
+    -   测试用例格式化结果目录如下：
+
+        ```
+        result/
+        ```
+
+    -   测试用例日志目录如下：
+
+        ```
+        log/plan_log_xxxx-xx-xx-xx-xx-xx.log
+        ```
+
+    -   测试报告汇总：
+
+        ```
+        summary_report.html
+        ```
+
+    -   测试报告详情：
+
+        ```
+        details_report.html
+        ```
+
+
+    -   测试平台日志目录如下：
+
+        ```
+        reports/platform_log_xxxx-xx-xx-xx-xx-xx.log
+        ```

+## 简介<a name="section11388623181619"></a>
+
+bytrace是开发人员用于追踪进程轨迹、分析性能的一种工具，主要对内核ftrace进行了封装和扩展，来支持用户态的打点。通过该工具可以打开想要查看的用户态和内核label（通过下面命令行bytrace -l，查看支持的所有label），然后通过命令行进行抓取trace信息到指定文件中。

+
+
+hdc\_std（OpenHarmony Device Connector）是OpenHarmony为开发人员提供的用于调试的命令行工具，通过该工具可以在Windows/Linux等系统上与开发机或者模拟器进行交互。
+
+下文将介绍hdc\_std的环境准备和常用命令及使用举例。
+
+## 环境准备<a name="section05992022154916"></a>
+
+**hdc\_std 工具获取方式：**
+
+从开源仓developtools\_hdc\_standard中获取，具体位置在该开源仓的prebuilt目录。
+
+**使用举例：**
+
+下面以windows侧使用方式举例：
+
+从prebuilt/windows侧获取可执行文件hdc\_std.exe，放到磁盘某个位置即可使用。
+
+## 注意事项<a name="section19543134915210"></a>
+
+-   使用hdc\_std，如果出现异常，可以尝试通过hdc\_std kill命令杀掉hdc\_std服务，或者通过hdc\_std start -r命令重启服务进程进行解决。
+-   如果出现hdc\_std list targets获取不到设备信息，通过任务管理器查看是否有hdc.exe进程存在，如果进程存在，可以通过杀掉该进程进行解决。
+
+## option相关的命令<a name="section618522925119"></a>

+## 常见问题<a name="section592920255582"></a>
+
+### hdc\_std连接不到设备<a name="section74019384588"></a>
+
+-   **现象描述**
+
+    执行 "hdc\_std list targets"命令后结果为：\[Empty\]
+
+-   **解决方法**
+    1.  设备没有被识别：
+
+        在设备管理器中查看是否有hdc设备，在通用串行总线设备中会有“HDC Device”信息。如果没有，hdc无法连接。此时需要插拔设备，或者烧写最新的镜像。
+
+    2.  hdc\_std工作异常：
+
+        可以执行"hdc kill"或者"hdc start -r"杀掉hdc服务或者重启hdc服务，然后再执行hdc list targets查看是否已经可以获取设备信息。
+
+    3.  hdc\_std与设备不匹配：
+
+        如果设备烧写的是最新镜像，hdc\_std也需要使用最新版本。由于hdc\_std会持续更新，请从开源仓developtools\_hdc\_standard中获取，具体位置在该开源仓的prebuilt目录。
+
+
+
+### hdc\_std运行不了<a name="section63291491267"></a>
+
+-   **现象描述**
+
+    点击hdc\_std.exe文件无法运行。
+
+-   **解决方法**
+
+    hdc\_std.exe不需要安装，直接放到磁盘上就能使用，也可以添加到环境变量中。通过打开cmd执行hdc\_std命令直接使用。

+
+### LiteOS-A内核\(Hi3516、Hi3518平台\)KV存储的native应用开发步骤：<a name="section258354119295"></a>
+
+1.  基于AbilityKit开发KV存储的native应用。
+    -   基于KV存储提供的接口编写用户程序，并编译出so（libLauncher.so）文件。
+
+        ```
+        // set
+        char key[] = "rw.sys.version_100";
+        char value[] = "Hello kv operation implement!";
+        int ret = UtilsSetValue(key, value);
+        printf("UtilsSetValue set ret = %d\n", ret);
+        
+        // get
+        char temp[128] = {0};
+        ret = UtilsGetValue(key, temp, 128);
+        printf("UtilsGetValue get ret = %d, temp = %s\n", ret, temp);
+        
+        // delete
+        ret = UtilsDeleteValue(key);
+        printf("UtilsDeleteValue delete ret = %d\n", ret);
+        ```
+
+    -   编写config.json文件，内容如下：
+
+        ```
+        {
+            "app": {

+            }
+        }
+        ```
+
+
+    -   生成hap包。
+
+        -   按照如下目录结构存放文件，res/drawable下面放置资源文件：
+
+        ![](figure/unnaming.png)
+
+        -   将上述文件打包生成zip包，修改后缀为.hap，例如Launcher.hap
+
+
+2.  连接单板，通过串口向单板发送安装KV存储native应用的命令。
+
+    ```
+    ./nfs/dev_tools/bin/bm install -p /nfs/Launcher.hap
+    ```
+
+3.  通过串口向单板发送运行KV存储native应用的命令。
+
+    ```
+    ./nfs/dev_tools/bin/aa start -p com.huawei.launcher -n ServiceAbility
+    ```

+## 简介<a name="section465982318513"></a>
+
+XTS子系统是OpenHarmony生态认证测试套件的集合，当前包括acts（application compatibility test suite）应用兼容性测试套件，后续会拓展dcts（device compatibility test suite）设备兼容性测试套件等。
+
+XTS子系统当前包括acts与tools软件包：
+
+-   acts，存放acts相关测试用例源码与配置文件，其目的是帮助终端设备厂商尽早发现软件与OpenHarmony的不兼容性，确保软件在整个开发过程中满足OpenHarmony的兼容性要求。
+-   tools，存放acts相关测试用例开发框架。
+
+## 系统类型<a name="section125090457443"></a>
+
+OpenHarmony支持如下几种系统类型：
+
+-   轻量系统（mini system）
+
+    面向MCU类处理器例如Arm Cortex-M、RISC-V 32位的设备，硬件资源极其有限，支持的设备最小内存为128KiB，可以提供多种轻量级网络协议，轻量级的图形框架，以及丰富的IOT总线读写部件等。可支撑的产品如智能家居领域的连接类模组、传感器设备、穿戴类设备等。
+
+-   小型系统（small system）
+
+    面向应用处理器例如Arm Cortex-A的设备，支持的设备最小内存为1MiB，可以提供更高的安全能力、标准的图形框架、视频编解码的多媒体能力。可支撑的产品如智能家居领域的IP Camera、电子猫眼、路由器以及智慧出行域的行车记录仪等。
+
+-   标准系统（standard system）
+
+    面向应用处理器例如Arm Cortex-A的设备，支持的设备最小内存为128MiB，可以提供增强的交互能力、3D GPU以及硬件合成能力、更多控件以及动效更丰富的图形能力、完整的应用框架。可支撑的产品如高端的冰箱显示屏。

+### C语言用例开发编译指导（适用于轻量系统产品用例开发）<a name="section198193336544"></a>
+
+**示例：轻量系统测试用例开发**
+
+当前使用的测试框架是hctest，hctest测试框架支持使用C语言编写测试用例，是在开源测试框架unity的基础上进行增强和适配。
+
+1.  用例目录规范：测试用例存储到test/xts/acts仓中
+
+    ```
+    ├── acts
+    │ └──subsystem_lite
+    │ │ └── module_hal
+    │ │ │ └── BUILD.gn
+    │ │ │ └── src
+    │ └──build_lite
+    │ │ └── BUILD.gn
+    ```
+
+2.  src目录下用例编写样例。
+
+    1.引用测试框架
+
+    ```
+    #include "hctest.h"
+    ```
+
+    2. 使用宏定义LITE\_TEST\_SUIT定义子系统、模块、测试套件名称
+
+    ```
+    /**  
+    * @brief  register a test suit named "IntTestSuite"  
+    * @param  test subsystem name  
+    * @param  example module name  
+    * @param  IntTestSuite test suit name  
+    */
+    LITE_TEST_SUIT(test, example, IntTestSuite);
+    ```
+
+    3. 定义Setup与TearDown
+
+    命名方式：测试套件名称+Setup，测试套件名称+TearDown。
+
+    Setup与TearDown必须存在，可以为空函数。
+
+    4. 使用宏定义LITE\_TEST\_CASE写测试用例
+
+    包括三个参数：测试套件名称，测试用例名称，用例属性（测试类型、用例粒度、用例级别）。
+
+    ```
+    LITE_TEST_CASE(IntTestSuite, TestCase001, Function | MediumTest | Level1) 
+    {  
+      //do something 
+    };
+    ```
+
+    5. 使用宏定义 RUN\_TEST\_SUITE注册测试套件
+
+    ```
+    RUN_TEST_SUITE(IntTestSuite);
+    ```
+
+3.  测试模块的配置文件（BUILD.gn）样例：
+
+    在每个测试模块目录下新建BUILD.gn编译文件，用于指定编译后静态库的名称、依赖的头文件、依赖的库等；具体写法如下：
+
+    ```
+    import("//test/xts/tools/lite/build/suite_lite.gni")
+    hctest_suite("ActsDemoTest") {
+        suite_name = "acts"
+        sources = [
+            "src/test_demo.c",
+        ]
+        include_dirs = [ ]
+        cflags = [ "-Wno-error" ]
+    }
+    ```
+
+4.  acts下BUILD.gn增加编译选项。
+
+    需要将测试模块加入到acts目录下的编译脚本中，编译脚本路径：test/xts/acts/build\_lite/BUILD.gn。
+
+    ```
+    lite_component("acts") {  
+        ...
+        if(board_name == "liteos_m") {
+            features += [    
+                ...
+                "//xts/acts/subsystem_lite/module_hal:ActsDemoTest"
+            ]    
+        }
+    }
+    ```
+
+5.  测试套件编译命令。
+
+    随版本编译，debug版本编译时会同步编译acts测试套件
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >acts测试套件编译中间件为静态库，最终链接到版本镜像中 。
+
+
+### C语言用例执行指导（适用于轻量系统产品用例开发）<a name="section13820233175418"></a>
+
+**示例：轻量系统测试用例执行**
+
+将版本镜像烧录进开发板。
+
+**测试步骤**
+
+1.  使用串口工具登录开发板，并保存串口打印信息。
+2.  重启设备，查看串口日志。
+
+**测试结果分析指导**
+
+基于串口打印日志进行分析；
+
+每个测试套件执行以Start to run test suite开始，以xx Tests xx Failures xx Ignored结束。
+
+### C++语言用例开发编译指导（适用于小型系统、标准系统用例开发）<a name="section3822123311540"></a>
+
+**示例：小型系统测试用例开发**（标准参考具体样例目录：global/i18n\_standard）
+
+当前使用的测试框架是hcpptest，hcpptest测试框架是在开源的googletest测试框架的基础上进行的增强和适配。
+
+1.  规范用例目录：测试用例存储到test/xts/acts仓中。
+
+    ```
+    ├── acts
+    │ └──subsystem_lite
+    │ │ └── module_posix
+    │ │ │ └── BUILD.gn
+    │ │ │ └── src
+    │ └──build_lite
+    │ │ └── BUILD.gn
+    ```
+
+2.  测试模块src下用例编写样例：
+
+    1. 引用测试框架：
+
+    需要引用gtest.h  如：\#include "gtest/gtest.h"
+
+    ```
+    #include "gtest/gtest.h"
+    ```
+
+    2. 定义Setup与TearDown
+
+    ```
+    using namespace std;
+    using namespace testing::ext;
+    class TestSuite: public testing::Test {
+    protected:
+    // Preset action of the test suite, which is executed before the first test case
+    static void SetUpTestCase(void){
+    }
+    // Test suite cleanup action, which is executed after the last test case
+    static void TearDownTestCase(void){
+    }
+    // Preset action of the test case
+    virtual void SetUp()
+    {
+    }
+    // Cleanup action of the test case
+    virtual void TearDown()
+    {
+    }
+    };
+    ```
+
+    3. 使用宏定义HWTEST或HWTEST\_F写测试用例
+
+    普通测试用例的定义：HWTEST（测试套名称， 测试用例名称， 用例标注）。
+
+    包含SetUp和TearDown的测试用例的定义 ：HWTEST\_F（测试套名称， 测试用例名称，用例标注）。
+
+    宏定义包括三个参数：测试套件名称，测试用例名称，用例属性（测试类型、用例粒度、用例级别）。
+
+    ```
+    HWTEST_F(TestSuite, TestCase_0001, Function | MediumTest | Level1) {
+    // do something
+    }
+    ```
+
+3.  测试模块下用例配置文件（BUILD.gn）样例：
+
+    每个测试模块目录下新建BUILD.gn编译文件，用于指定编译后可执行文件的名称、依赖的头文件、依赖的库等；具体写法如下。每个测试模块将独立编译成.bin可执行文件， 该文件可直接push到单板上进行测试。
+
+    举例：
+
+    ```
+    import("//test/xts/tools/lite/build/suite_lite.gni")
+    hcpptest_suite("ActsDemoTest") {
+        suite_name = "acts"
+        sources = [
+            "src/TestDemo.cpp"
+        ]
+    
+        include_dirs = [
+            "src",
+            ...
+        ]
+        deps = [
+            ...
+        ]
+        cflags = [ "-Wno-error" ]
+    }
+    
+    ```
+
+4.  acts目录下增加编译选项（BUILD.gn）样例：
+
+    将测试模块加入到acts目录下的编译脚本中，编译脚本为：test/xts/acts/build\_lite/BUILD.gn。
+
+    ```
+     lite_component("acts") {  
+    ...
+    else if(board_name == "liteos_a") {
+            features += [
+                ...
+                "//xts/acts/subsystem_lite/module_posix:ActsDemoTest"
+            ]
+        }
+    }
+    ```
+
+5.  测试套件编译命令。
+
+    随版本编译，debug版本编译时会同步编译acts测试套件
+
+    >![](../public_sys-resources/icon-note.gif) **说明：** 
+    >小型系统acts独立编译成可执行文件（bin格式）， 在编译产物的suites\\acts目录下归档。
+
+
+### C++语言用例执行指导（适用于小型系统、标准系统用例开发）<a name="section128222336544"></a>
+
+**示例：小型系统测试用例执行**
+
+目前的用例执行采用nfs共享的方式，mount到单板去执行。
+
+**环境搭建**
+
+1.  使用有限网线或无线将开发板与PC进行连接。
+2.  开发板配置IP、子网掩码、网关，确保开发板与PC处于同一个网段。
+3.  PC安装nfs服务器并完成注册，启动nfs服务。
+4.  开发板配置mount命令，确保开发板可以访问PC端的nfs共享文件。
+
+    格式：mount \[nfs服务器IP\]:\[/nfs共享目录\] \[/开发板目录\] nfs
+
+    举例：
+
+    ```
+    mount 192.168.1.10:/nfs /nfs nfs
+    ```
+
+
+**用例执行**
+
+测试套件执行 ActsDemoTest.bin 触发用例执行，基于串口打印日志进行分析。
+
+### JS语言用例开发指导（适用于标准系统）<a name="section159801435165220"></a>
+
+当前使用的测试框架是HJSUnit，用于支撑OpenHarmony application测试（特指基于JS应用框架使用 Javascript 语言开发的 APP）进行自动化测试。

+用例编写语法采用 jasmine 的标准语法，格式支持ES6格式。
+
+1.  规范用例目录：测试用例存储到entry/src/main/js/test目录。
+
+    ```
+    ├── BUILD.gn   
+    │ └──entry
+    │ │ └──src
+    │ │ │ └──main
+    │ │ │ │ └──js
+    │ │ │ │ │ └──default               
+    │ │ │ │ │ │ └──pages
+    │ │ │ │ │ │ │ └──index             
+    │ │ │ │ │ │ │ │ └──index.js        # 入口文件
+    │ │ │ │ │ └──test                  # 测试代码存放目录  
+    │ │ │ └── resources                # hap资源存放目录
+    │ │ │ └── config.json              # hap配置文件
+    ```
+
+2.  index.js示例
+
+    ```
+    // 拉起js测试框架，加载测试用例
+    import {Core, ExpectExtend} from 'deccjsunit/index'
+    
+    export default {
+        data: {
+            title: ""
+        },
+        onInit() {
+            this.title = this.$t('strings.world');
+        },
+        onShow() {
+            console.info('onShow finish')
+            const core = Core.getInstance()
+            const expectExtend = new ExpectExtend({
+                'id': 'extend'
+            })
+            core.addService('expect', expectExtend)
+            core.init()
+            const configService = core.getDefaultService('config')
+            configService.setConfig(this)
+            require('../../../test/List.test')
+            core.execute()
+        },
+        onReady() {
+        },
+    }
+    ```
+
+3.  单元测试用例示例
+
+    ```
+    // Example1: 使用HJSUnit进行单元测试
+    describe('appInfoTest', function () {    
+        it('app_info_test_001', 0, function () {
+            var info = app.getInfo()
+            expect(info.versionName).assertEqual('1.0')
+            expect(info.versionCode).assertEqual('3')
+        })
+    }) 
+    ```

+
+hap包编译请参考[标准系统js应用开发指导](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/build_overview-0000001055075201)。
+
+## 全量编译指导（适用于标准系统）<a name="section1519992743415"></a>
+
+1.  全量编译
+
+    **命令**：
+
+    ```
+    ./build.sh suite=acts system_size=standard
+    ```
+
+    **测试用例输出目录**：out/release/suites/acts/testcases
+
+    **测试框架&用例整体输出目录：**out/release/suites/acts（编译用例时会同步编译测试套执行框架）
+
+
+## 全量用例执行指导（适用于小型系统、标准系统）<a name="section118149111426"></a>
+
+**搭建测试环境**
+
+Windows工作台下安装python3.7及以上版本，确保工作台和测试设备正常连接。
+
+**测试执行目录**（对应编译生成的out/release/suites/acts目录）
+
+```
+├── testcase                       # 测试套文件存放目录 
+│ └──xxx.hap                       # 测试套可执行hap文件
+│ └──xxx.json                      # 测试套对应执行配置文件
+├── tools                          # 测试框架工具目录
+├── run.bat                        # window平台测试套启动执行文件
+├── report                         # 测试报告生成目录
+```
+
+**用例执行**
+
+1.  在Windows工作台上，找到从Linux服务器上拷贝下来的测试套件用例目录\(对应编译生成的out/release/suites/acts目录\)，在Windows命令窗口进入对应目录，直接执行acts\\run.bat。
+
+1.  界面启动后，输入用例执行指令。
+
+    -   全量执行
+
+        ```
+        run acts
+        ```
+
+        ![](figure/zh-cn_image_0000001119924146.gif)
+
+
+    -   模块执行\(具体模块可以查看\\acts\\testcases\\\)
+
+        ```
+        run –l ActsSamgrTest
+        ```
+
+        ![](figure/zh-cn_image_0000001166643927.jpg)
+
+
+    等待执行完成。
+
+
+1.  查看测试报告。
+
+    进入acts\\reports\\，获取当前的执行记录，打开“summary\_report.html”可以获取到测试报告。

-AI引擎框架包含client、server和common三个主要模块，其中client提供server端连接管理功能，北向SDK在算法对外接口中需封装调用client提供的公共接口；server提供插件加载以及任务管理等功能，各Plugin实现由server提供的插件接口，完成插件接入；common提供与平台相关的操作方法、引擎协议以及相关工具类，供其他各模块调用。
-
-AI引擎框架各模块之间的代码依赖关系如下[图1](#fig171811112818)所示：
-
-**图 1** ****AI引擎代码依赖关系<a name="fig171811112818"></a>

-
-![](figures/插件依赖-(2).jpg)
-
-## 建议：插件与北向SDK在AI引擎指定的路径下进行代码开发<a name="section17176374131"></a>
-
-在AI引擎框架的整体规划中，北向SDK属于client端的一部分，插件由server端调用，属于server端的一部分，因此AI引擎框架为接入的插件与北向SDK规划的路径：
-
--   SDK代码路径：//foundation/ai/engine/services/client/algorithm\_sdk
-
-    e.g. //foundation/ai/engine/services/client/algorithm\_sdk/cv
-
-    e.g. //foundation/ai/engine/services/client/algorithm\_sdk/nlu
-
--   插件代码路径：//foundation/ai/engine/services/server/plugin
-
-    e.g. //foundation/ai/engine/services/server/plugin/cv
-
-    e.g. //foundation/ai/engine/services/server/plugin/nlu
-
-
-## 规则：插件提供的全部对外接口，统一存放在AI业务子系统interfaces/kits目录<a name="section2551029111312"></a>
-
-北向SDK对外接口是AI业务子系统提供能力的对外暴露方式，按照OpenHarmony的接口管理要求，需统一存放在各子系统的interfaces/kits目录中。当前AI业务子系统插件对外接口路径为//foundation/ai/engine/interfaces/kits，不同插件可在该路径下添加目录，比如增加cv插件，则在路径//foundation/ai/engine/interfaces/kits/cv下面存放接口文件。
-
-## 规则：插件编译输出路径必须是在/usr/lib<a name="section97021558121310"></a>
-
-server端加载插件是采用dlopen方式，只支持在/usr/lib路径进行，因此插件在编译so时，需要在编译配置文件中指定输出路径为/usr/lib。

-### LiteOS-A内核\(Hi3516、Hi3518平台\)KV存储的native应用开发步骤：<a name="section258354119295"></a>
-
-1.  基于AbilityKit开发KV存储的native应用。
-    -   基于KV存储提供的接口编写用户程序，并编译出so（libLauncher.so）文件。
-
-        ```
-        // set
-        char key[] = "rw.sys.version_100";
-        char value[] = "Hello kv operation implement!";
-        int ret = UtilsSetValue(key, value);
-        printf("UtilsSetValue set ret = %d\n", ret);
-        
-        // get
-        char temp[128] = {0};
-        ret = UtilsGetValue(key, temp, 128);
-        printf("UtilsGetValue get ret = %d, temp = %s\n", ret, temp);
-        
-        // delete
-        ret = UtilsDeleteValue(key);
-        printf("UtilsDeleteValue delete ret = %d\n", ret);
-        ```

-## 使用场景<a name="section726685714018"></a>
-
-UI动画通过task处理机制每个tick调用一下用户设置的callback函数来实现，具体实现为AnimatorManager、Animator、AnimatorCallback三个类实现。
-
--   AnimatorManager：AnimatorManager为单例，在Init函数执行时将自己注册到系统task回调函数中，系统task机制保证每个tick会调用一下AnimatorManager的callback函数，同时AnimatorManager用来管理Animator实例。
--   Animator：Animator中可以设置动画相关的属性，包括动画的起止时间，动画开始和停止，动画状态的设置和获取等。
--   AnimatorCallback：具体每一个tick动画所要做的内容在AnimatorCallback类中实现，开发者需要自己实现Callback方法，动画执行时在Callback实现相应功能。

-## 开发步骤<a name="section14101161317435"></a>
-
-1.  实现AnimatorCallback的回调函数。
-
-    ```
-    class AnimatorCallbackDemo : public OHOS::AnimatorCallback {
-    public:
-        AnimatorCallbackDemo(int16_t startPos, int16_t endPos, uint16_t time)
-            : start_(startPos), end_(endPos), time_(time), curTime_(0) {}
-     
-        virtual void Callback(OHOS::UIView* view)
-        {
-            curTime_++;
-            int16_t pos = EasingEquation::CubicEaseIn(start_, end_, curTime_, time_);
-            view->Invalidate();
-            view->SetPosition(pos, view->GetY());
-            view->Invalidate();
-        }
-    protected:
-        int16_t start_;
-        int16_t end_;
-        uint16_t time_;
-        uint16_t curTime_;
-    };
-    ```
-
-2.  将AnimatorCallback添加到Animator中。
-
-    ```
-    UIImageView* image = new UIImageView();
-    image->SetSrc("..\\config\\images\\A021_001.bin");
-    image->SetPosition(0, 50);
-    AnimatorCallbackDemo* callback = new AnimatorCallbackDemo(0, 338, 60);
-    Animator* animator = new Animator(callback, image, 0, true);
-    ```
-
-3.  将Animator添加到AnimatorManager中。
-
-    ```
-    AnimatorManager::GetInstance()->Add(animator);
-    ```
-
-4.  点击下图下方的按钮，检查对应的动画运行效果。

-启动恢复子系统负责从内核启动之后到应用启动之前的系统关键服务进程的启动过程以及设备恢复出厂设置的功能。涉及以下组件：
-
--   init启动引导组件
-
-    init启动引导组件对应的进程为init进程，是内核完成初始化后启动的第一个用户态进程。init进程启动之后，读取init.cfg配置文件，根据解析结果，执行相应命令（见[第2章表2](init启动引导组件.md#table122681439144112)描述）并依次启动各关键系统服务进程，在启动系统服务进程的同时设置其对应权限。
-
--   appspawn应用孵化组件
-
-    负责接收**用户程序框架**的命令孵化应用进程，设置新进程的权限，并调用应用程序框架的入口函数。
-
--   bootstrap服务启动组件
-
-    提供了各服务和功能的启动入口标识。在SAMGR启动时，会调用boostrap标识的入口函数，并启动系统服务。
-
--   syspara系统属性组件
-
-    系统属性组件，根据OpenHarmony产品兼容性规范提供获取设备信息的接口，如：产品名、品牌名、厂家名等，同时提供设置/读取系统属性的接口。

-# 唤醒词识别SDK的开发示例<a name="ZH-CN_TOPIC_0000001090776709"></a>
-
-1.  在//foundation/ai/engine /interfaces/kits目录中添加唤醒词识别SDK的API接口定义，该接口可用三方应用的调用。如下代码片段即为唤醒词识别定义的API接口示例，其相关代码参考路径为：//foundation/ai/engine /interfaces/kits/asr/keyword\_spotting。
-
-    ```
-    class KWSSdk {
-    public:
-        KWSSdk();
-        virtual ~KWSSdk();
-    
-        // 定义了创建唤醒词检测工具包的方法
-        int32_t Create();
-    
-        // 定义了同步执行唤醒词检测任务的方法
-        int32_t SyncExecute(const Array<int16_t> &audioInput);
-    
-        // 定义了设置唤醒词检测回调器的方法
-        int32_t SetCallback(const std::shared_ptr<KWSCallback> &callback);
-    
-        // 定义了销毁唤醒词工具包的方法，释放与插件的会话信息。
-        int32_t Destroy();
-    };
-    ```
-
-2.  在//foundation/ai/engine/services/client/algorithm\_sdk的目录中增加SDK中API接口的具体实现，调用client端提供的接口，实现算法插件能力的使用。如下代码片段即为唤醒词识别的API接口中create方法的具体实现示例，更多详细代码可参考：//foundation/ai/engine/services/client/algorithm\_sdk/asr/keyword\_spotting。
-
-    ```
-    int32_t KWSSdk::KWSSdkImpl::Create()
-    {
-        if (kwsHandle_ != INVALID_KWS_HANDLE) {
-            HILOGE("[KWSSdkImpl]The SDK has been created");
-            return KWS_RETCODE_FAILURE;
-        }
-        if (InitComponents() != RETCODE_SUCCESS) {
-            HILOGE("[KWSSdkImpl]Fail to init sdk components");
-            return KWS_RETCODE_FAILURE;
-        }
-        // 调用client端提供的接口AieClientInit，实现初始化引擎服务，激活跨进程调用
-        int32_t retCode = AieClientInit(configInfo_, clientInfo_, algorithmInfo_, nullptr);
-        if (retCode != RETCODE_SUCCESS) {
-            HILOGE("[KWSSdkImpl]AieClientInit failed. Error code[%d]", retCode);
-            return KWS_RETCODE_FAILURE;
-        }
-        if (clientInfo_.clientId == INVALID_CLIENT_ID) {
-            HILOGE("[KWSSdkImpl]Fail to allocate client id");
-            return KWS_RETCODE_FAILURE;
-        }
-        DataInfo inputInfo = {
-            .data = nullptr,
-            .length = 0,
-        };
-        DataInfo outputInfo = {
-            .data = nullptr,
-            .length = 0,
-        };
-        // 调用client端提供的接口AieClientPrepare，实现加载算法插件
-        retCode = AieClientPrepare(clientInfo_, algorithmInfo_, inputInfo, outputInfo, nullptr);
-        if (retCode != RETCODE_SUCCESS) {
-            HILOGE("[KWSSdkImpl]AieclientPrepare failed. Error code[%d]", retCode);
-            return KWS_RETCODE_FAILURE;
-        }
-        if (outputInfo.data == nullptr || outputInfo.length <= 0) {
-            HILOGE("[KWSSdkImpl]The data or length of output info is invalid");
-            return KWS_RETCODE_FAILURE;
-        }
-        MallocPointerGuard<unsigned char> pointerGuard(outputInfo.data);
-        retCode = PluginHelper::UnSerializeHandle(outputInfo, kwsHandle_);
-        if (retCode != RETCODE_SUCCESS) {
-            HILOGE("[KWSSdkImpl]Get handle from inputInfo failed");
-            return KWS_RETCODE_FAILURE;
-        }
-        return KWS_RETCODE_SUCCESS;
-    }
-    ```
-
-    上述代码为API接口的具体实现，从上述示例的代码中，SDK中create接口的具体实现即为下述示例代码中create方法，该方法调用了AI引擎框架client端开放接口AieClientInit，AieClientPrepare，从而实现与server端建立连接及加载算法模型的能力。
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >SDK调用AI引擎client端接口顺序应遵循AieClientInit-\>AieClientPrepare-\>AieClientSyncProcess/AieClientAsyncProcess-\>AieClientRelease-\>AieClientDestroy，否则调用接口会返回错误码。

-容器类组件，指能包含其它UI组件的组件，容器类组件继承于UIViewGroup（带Add方法），基于实际组件的使用场景，将需要增加其他子组件的组件，放置到容器类继承结构下。如UIAnalogClock内，通常会Add需要的计步信息，时分秒图标等。

-
-RootView、UIAbstractScroll、UIPicker组件从UIViewGroup继承，UIList、UIScrollView、UISwipeView组件从UIAbstractScroll继承。

-UIViewGroup是容器类组件基类，实现增加、删除、插入等操作，通过增加方法可以添加子组件。普通容器类组件子组件需要设置位置信息，位置信息为相对父组件的相对坐标。组件树结构如下图：
-
-**图 2**  组件树结构示意图<a name="fig279970183012"></a>  
-![](figures/组件树结构示意图.png "组件树结构示意图")
-
-往根节点rootView里添加ViewGroup1容器组件和View1组件，往ViewGroup1容器组件里再添加View2组件和ViewGroup2容器组件，在View1之后添加View3组件。
-
--   关于渲染：容器类组件在渲染时会遍历所有子组件OnDraw方法，以达到刷新所有组件的目的。
--   关于坐标：子组件位置信息为相对父组件的相对坐标，系统在渲染时计算绝对坐标并显示。
--   关于树结构遍历：UIViewGroup提供如下方法实现遍历、查找、管理组件树。

-    btn1->SetPosition(0, 0, 100, 50);
-    btn1->SetText("btn1");
-    
-    UILabelButton* btn2 = new UILabelButton();
-    btn2->SetPosition(50, 50, 100, 50);
-    btn2->SetText("btn2");
-    
-    UILabelButton* btn3 = new UILabelButton();
-    btn3->SetPosition(100, 100, 100, 50);
-    btn3->SetText("btn3");
-    ```
-
-2.  构造UIViewGroup实例，并设置坐标信息。
-
-    ```
-    UIViewGroup* group = new UIViewGroup();
-    group->SetPosition(0, 0, 300, 300);
-    ```
-
-3.  使用Add方法添加Button实例到UIViewGroup。

-UISwipeView继承UIViewGroup，除提供容器类组件Add、Remove、Insert等方法外还提供按页面滑动功能，滑动结束后当前页面居中对齐显示。该组件分为水平方向和垂直方向，通过Add方法添加的子组件会根据Add的顺序和UISwipeView方向自动水平对齐或则垂直对齐。

-1.  创建一个水平滑动的UISwipeView。
-
-    ```
-    UISwipeView* swipe = new UISwipeView(UISwipeView::HORIZONTAL);
-    ```
-
-2.  向UISwipeView中添加子组件。
-
-    ```
-    UILabelButton* button1 = new UILabelButton();
-    button1->SetPosition(0, 0, g_ButtonW, g_ButtonH);
-    button1->SetText("button1");
-    swipe->Add(button1);
-    UILabelButton* button2 = new UILabelButton();
-    button2->SetPosition(0, 0, g_ButtonW, g_ButtonH);
-    button2->SetText("button2");
-    swipe->Add(button2);
-    UILabelButton* button3 = new UILabelButton();
-    button3->SetPosition(0, 0, g_ButtonW, g_ButtonH);
-    button3->SetText("button3");
-    swipe->Add(button3);
-    ```
-
-3.  检查实现效果，水平滑动，不可循环。

-## 开发步骤<a name="section1418253410306"></a>
-
-1.  构造GridLayout并设置位置、大小信息。
-
-    ```
-    GridLayout* layout_ = new GridLayout();
-    layout_->SetPosition(0, g_y, HROIZONTAL_RESOLUTION, 200);
-    layout_->SetLayoutDirection(LAYOUT_HOR);
-    layout_->SetRows(2);
-    layout_->SetCols(2);
-    ```
-
-2.  构造子组件button。
-
-    ```
-    UILabelButton* bt1 = new UILabelButton();
-    bt1->SetPosition(0,0,100,50);
-    bt1->SetText("bt1");
-    UILabelButton* bt2 = new UILabelButton();
-    bt2->SetPosition(0, 0, 100, 50);
-    bt2->SetText("bt2");
-    UILabelButton* bt3 = new UILabelButton();
-    bt3->SetPosition(0, 0, 100, 50);
-    bt3->SetText("bt3");
-    UILabelButton* bt4 = new UILabelButton();
-    bt4->SetPosition(0, 0, 100, 50);
-    bt4->SetText("bt4");
-    ```
-
-3.  添加子组件并调用LayoutChildren\(\)。
-
-    ```
-    layout_->Add(bt1);
-    layout_->Add(bt2);
-    layout_->Add(bt3);
-    layout_->Add(bt4);
-    layout_->LayoutChildren();
-    ```
-
-4.  检查button组件布局效果如下图所示。

-## 系统启动过程中打印“parse failed!”错误后停止启动<a name="section2041345718513"></a>
-
-**现象描述**
-
-系统启动过程中，打印“\[Init\] InitReadCfg, parse failed! please check file /etc/init.cfg format.”错误，启动过程停止，如下图所示：
-
-![](figures/zh-cn_image_0000001063839940.png)
-
-**可能原因**
-
-修改init.cfg文件时，漏掉或多加了逗号或括号等，导致init.cfg文件的json格式被破坏。
-
-**解决办法**
-
-仔细检查init.cfg文件，确保其格式符合json格式要求。
-
-## 系统启动过程未结束就自动重启，如此反复持续<a name="section57381816168"></a>
-
-**现象描述**
-
-镜像烧写完成后系统启动，启动过程未完成即自动重新启动，如此反复持续。
-
-**可能原因**
-
-被init启动的服务都有一个叫做“importance”的属性（详见[第2章表3](init启动引导组件.md#table14737791471)描述）。
-
--   当该属性为0时，表示若当前服务进程退出，init不需要重启单板。
--   当该属性为1时，表示若当前服务进程退出，init需要重启单板。
-
-因此出现上述现象的可能原因：有“importance”属性为1的服务在每次启动的过程中都会退出（可能是进程崩溃或出错自动退出），导致init进程自动重启单板。
-
-**解决办法**
-
-1.  需要通过日志确认崩溃或报错退出的服务，并解决其崩溃/报错的问题，然后重新烧写镜像即可。
-2.  也可以将崩溃/报错退出的服务的“importance”属性改为0，然后重新烧写镜像，这样即使其退出，init也不会重启单板。
-
-## 参数正确的情况下调用SetParameter/GetParameter返回失败<a name="section129991227141512"></a>
-
-**现象描述**
-
-在各参数正确的情况下调用SetParameter/GetParameter返回失败。
-
-**可能原因**
-
-程序对SetParameter/GetParameter这两个接口做了权限校验，在各参数正确的情况下调用SetParameter/GetParameter返回操作失败，很有可能是调用者的uid大于1000，没有调用权限。
-
-**解决办法**
-
-无需处理

-## 运作机制<a name="section193961322175011"></a>
-
-由于OpenHarmony允许安装三方应用，所以需要对三方应用的敏感权限调用进行管控，具体实现是应用在开发阶段就需要在profile.json中指明此应用在运行过程中可能会调用哪些敏感权限，这些权限包括静态权限和动态权限，静态权限表示只需要在安装阶段注册就可以，而动态权限一般表示获取用户的敏感信息，所以需要在运行时让用户确认才可以调用，授权方式包括系统设置应用手动授权等。除了运行时对应用调用敏感权限进行管控外，还需要利用应用签名管控手段确保应用安装包已经被设备厂商进行了确认。

-## 场景介绍<a name="section18502174174019"></a>
-
-应用权限是软件用来访问系统资源和使用系统能力的一种通行方式。在涉及用户隐私相关功能和数据的场景，例如：访问个人设备的硬件特性，如摄像头、麦克风，以及读写媒体文件等，OpenHarmony通过应用权限管理组件来保护这些数据以及能力。
-
-在系统应用开发过程中，如果应用要使用敏感权限，开发者可以调用应用权限管理组件接口检查待访问权限是否被授权，如果未授权，操作不允许。
-
-## 接口说明<a name="section1633115419401"></a>

-## 开发步骤<a name="section022611498210"></a>
-
-本部分以包管理器的应用权限开发为例进行讲解。开发过程中，首先需要明确涉及的敏感权限，并在config.json中声明该权限，在安装应用程序时，包管理器会调用应用权限管理组件的接口检查该权限是否被授予，若授予，安装流程正常进行，否则安装失败。
-
-1.  在开发过程中，包管理器明确需要安装应用的权限（ohos.permission.INSTALL\_BUNDLE），并在config.json中声明该权限；
-
-    ```
-    {
-      ...
-      "module": {
-          "package": "com.huawei.kitframework",
-          "deviceType": [
-              "phone", "tv","tablet", "pc","car","smartWatch","sportsWatch","smartCamera", "smartVision"
-          ],
-          "reqPermissions": [{
-            // 声明需要的权限：安装应用程序的权限名
-            "name": "ohos.permission.INSTALL_BUNDLE",   
-            "reason": "install bundle",
-            "usedScene": {
-              "ability": [
-                "KitFramework"
-                ],
-              "when": "always"
-            }
-          },
-          {
-            "name": "ohos.permission.LISTEN_BUNDLE_CHANGE",
-            "reason": "install bundle",
-            "usedScene": {
-              "ability": [
-                "KitFramework"
-                ],
-              "when": "always"
-            }
-          },
-          {
-            "name": "ohos.permission.GET_BUNDLE_INFO",
-            "reason": "install bundle",
-            "usedScene": {
-              "ability": [
-                "KitFramework"
-                ],
-              "when": "always"
-            }
-          }
-          ],
-        ...
-    }
-    ```
-
-2.  当包管理器开发应用安装功能接口时，会调用权限管理相关接口检查自身是否具有安装应用程序的权限，例如：以安装应用的权限名"ohos.permission.INSTALL\_BUNDLE"作为入参，调用CheckPermission接口检查包管理器是否具有安装应用的权限，如果有权限，安装流程继续执行，否则返回安装失败；
-
-    ```
-    constexpr static char PERMISSION_INSTALL_BUNDLE[] = "ohos.permission.INSTALL_BUNDLE";
-    
-    bool Install(const char *hapPath, const InstallParam *installParam, InstallerCallback installerCallback)
-    {
-        if ((hapPath == nullptr) || (installerCallback == nullptr) || (installParam == nullptr)) {
-            HILOG_ERROR(HILOG_MODULE_APP, "BundleManager install failed due to nullptr parameters");
-            return false;
-        }
-        // 检查ohos.permission.INSTALL_BUNDLE权限是否被授予
-        if (CheckPermission(0, static_cast<const char *>(PERMISSION_INSTALL_BUNDLE)) != GRANTED) {
-            HILOG_ERROR(HILOG_MODULE_APP, "BundleManager install failed due to permission denied");
-            return false;  // 返回安装失败
-        }
-        // 安装流程
-        ...
-    }
-    ```

-## 场景介绍<a name="section18502174174019"></a>
-
-当需要验证调试应用、发布应用，OpenHarmony自签名应用的完整性是否被破坏时，可以调用验签组件的接口进行验证。如有需要还可通过验签接口获取部分描述文件信息，如appid。对于调试应用，还可通过验签接口验证应用和设备的UDID是否匹配，确保应用安装在了正确的设备上。
-
-## 验签流程<a name="section554632717226"></a>
-
-未经签名的Hap包的压缩方式是ZIP格式，简单分为文件块，中心目录（Central directory）块，中心目录结尾（EOCD，End of central directory record）块。
-
-经过签名的Hap包，在文件块，和中心目录块之间，插入了签名块。签名块由文件签名数据块（data sign block）、描述文件签名数据块（profile sign block）和签名头（sign head）组成，如下图所示。
-
-**图 1**  经过签名的Hap包结构<a name="fig699855043"></a>  
-
-
-![](figures/安全子系统.png)
-
-整个验签流程，主要分为三部分：整包验签、描述文件签名块验签，以及描述文件内容校验。
-
-**整包验签**
-
-用设备的预置根证书，通过证书链来证明叶子证书本身是可信的，然后用叶子证书的公钥解密出的摘要证明整包是未篡改的。
-
-具体操作步骤如下：
-
-1.  对文件签名数据块中的证书链进行校验，确定其叶子证书是可信的。
-2.  用叶子证书中的公钥对文件签名块进行验签，证明其未被篡改。
-3.  计算并合并文件块，中心目录块和中心目录结尾块的摘要。然后将计算结果，再与签名块中的描述文件签名块的摘要合并，将最终合并的摘要与文件签名块中包含的摘要对比，如果两者相等，则整包验签通过。
-
-**描述文件签名块验签**
-
-首先判断文件签名的签发单位，如果是应用市场签发的发布应用，则无需对描述文件进行验签，直接信任，否则要对其验签。先取出整个描述文件签名块，然后验证证书链，最后用叶子证书对描述文件数据块验签，证明其未被篡改。
-
-**描述文件内容校验**
-
-取出描述文件，并对其内容进行合法性检查。其中若hap包为调试应用，则会比对本机UDID与描述文件中包含的UDID列表，如果本机UDID在描述文件的UDID列表中包含，则验证通过。比较描述文件中包含的证书（如果是应用市场发布应用或OpenHarmony自签名则无需比较），和整包校验时使用的叶子证书，如果相同，认为整个验签流程完成。

-
-对应用市场发布应用、基于应用市场调试证书签发的调试应用、OpenHarmony自签名应用的校验。
-
-1.  定义出参结构体变量VerifyResult；
-
-    ```
-    VerifyResult verifyResult = {0};
-    ```
-
-2.  以文件路径及VerifyResult为入参，调用APPVERI\_AppVerify进行文件校验；
-
-    ```
-    int32_t ret = APPVERI_AppVerify(hapFilepath.c_str(), &verifyResult);
-    ```
-
-3.  判断返回结果，如果校验通过的话，获取VerifyResult中的数据，进行业务处理;
-
-    ```
-    signatureInfo.appId = verifyResult.profile.appid;
-    signatureInfo.provisionBundleName = verifyResult.profile.bundleInfo.bundleName;
-    ```
-
-4.  调用APPVERI\_FreeVerifyRst，释放VerifyResult中申请的内存。
-
-    ```
-    APPVERI_FreeVerifyRst(&verifyResult);
-    ```
-
-
-### 生成OpenHarmony自签名应用<a name="section167151429133312"></a>
-
-如果是OpenHarmony自签名应用的校验，开发者可通过以下方式生成OpenHarmony自签名应用。
-
-1.  材料备齐。
-
-    生成自签名应用需要的材料有：签名工具、系统应用hap包、系统应用profile文件\(\*.p7b\)、签名证书\(\*.cer\)、签名公私钥对\(\*.jks\)。
-
-2.  将所有材料放在同一个目录下，打开shell。
-3.  根据应用、描述文件的实际名称修改指令，并在shell中输入，完成签名。
-
-    ```
-    java -jar hapsigntoolv2.jar sign -mode localjks -privatekey "OpenHarmony Software Signature" -inputFile camera.hap -outputFile signed_camera.hap -signAlg SHA256withECDSA -keystore OpenHarmony.jks -keystorepasswd 123456 -keyaliaspasswd 123456 -profile camera_release.p7b -certpath OpenHarmony.cer -profileSigned 1

-
-    -certpath：使用签名证书，位于开源库security\_services\_app\_verify仓中OpenHarmonyCer目录下，[OpenHarmony.cer](https://gitee.com/openharmony/security_appverify/blob/master/interfaces/innerkits/appverify_lite/OpenHarmonyCer/OpenHarmony.cer)
-
-    -profileSigned：签名块中是否包含描述文件\(profile\)。固定为1（包含）
-
-
-### 开发示例<a name="section174318361353"></a>
-
-以应用管理框架组件在应用安装时进行验签的实际调用为例：
-
-```
-uint8_t HapSignVerify::VerifySignature(const std::string &hapFilepath, SignatureInfo &signatureInfo)
-{
-	bool mode = ManagerService::GetInstance().IsDebugMode();
-	HILOG_INFO(HILOG_MODULE_APP, "current mode is %d!", mode);
-        // 定义结果结构体
-	VerifyResult verifyResult = {0};
-        // 输入待验签文件路径进行验签
-	int32_t ret = APPVERI_AppVerify(hapFilepath.c_str(), &verifyResult); 
-	uint8_t errorCode = SwitchErrorCode(ret);
-	if (errorCode != ERR_OK) {
-		return errorCode;
-	}
-        // 从结果结构体中获取appid
-	signatureInfo.appId = verifyResult.profile.appid; 
-        // 从结果结构体中获取描述文件中书写的应用名
-	signatureInfo.provisionBundleName = verifyResult.profile.bundleInfo.bundleName; 
-	int32_t restricNum = verifyResult.profile.permission.restricNum;
-	for (int32_t i = 0; i < restricNum; i++) {
-		signatureInfo.restrictedPermissions.emplace_back((verifyResult.profile.permission.restricPermission)[i]);
-	}
-        // 释放结果结构体中申请的内存
-	APPVERI_FreeVerifyRst(&verifyResult); 
-	return ERR_OK;
-}

-
-### 验签指导<a name="section07028210442"></a>
-
-对采用基于测试根密钥证书签名的应用的校验。
-
-1.  调用APPVERI\_SetDebugMode\(true\)开启测试模式；
-
-    ```
-    	ManagerService::SetDebugMode(true);
-    ...
-    uint8_t ManagerService::SetDebugMode(bool enable)
-    {
-    	int32_t ret = APPVERI_SetDebugMode(enable);
-    	if (ret < 0) {
-    		HILOG_ERROR(HILOG_MODULE_APP, "set signature debug mode failed");
-    		return ERR_APPEXECFWK_SET_DEBUG_MODE_ERROR;
-    	}
-    	isDebugMode_ = enable;
-    	HILOG_INFO(HILOG_MODULE_APP, "current sign debug mode is %d", isDebugMode_);
-    	return ERR_OK;
-    }
-    ```
-
-2.  同场景一中步骤一至四，定义结构体，校验、释放结构体；
-3.  调用APPVERI\_SetDebugMode\(false\)关闭测试模式。
-
-    ```
-            ManagerService::SetDebugMode(false);
-    ```
-
-
-### 开发示例<a name="section1930711345445"></a>

-当应用触发去电动作时，RIL Adapter会接收到拨打电话的请求，OnRequest\(\)会根据拨打电话请求ID调用拨打电话的接口。在该接口里会把电话服务传过来的数据封装为对应的AT指令发送到Modem，Modem执行完拨号命令后通过OnRequestResponse\(\)接口把响应结果上报给RIL Adapter。

-## 开发步骤<a name="section10514141679"></a>
-
-### 创建Service类型的Ability<a name="section19921154214315"></a>
-
-1.  在my\_service\_ability.h中创建Ability的子类MyServiceAbility。
-
-    ```
-    class MyServiceAbility: public Ability {
-    protected:
-        void OnStart(const Want& want);
-        const SvcIdentity *OnConnect(const Want &want) override;
-        void MsgHandle(uint32_t funcId, IpcIo *request, IpcIo *reply) override;
-    };
-    ```
-
-2.  调用REGISTER\_AA宏将ServiceAbility注册到应用框架中，以便应用框架实例化开发者的MyServiceAbility。
-
-    ```
-    #include "my_service_ability.h"
-    
-    REGISTER_AA(ServiceAbility)
-    
-    void MyServiceAbility::OnStart(const Want& want)
-    {
-        printf("ServiceAbility::OnStart\n");
-        Ability::OnStart(want);
-    }
-    
-    const SvcIdentity *MyServiceAbility::OnConnect(const Want &want)
-    {
-        printf("ServiceAbility::OnConnect\n");
-        return Ability::OnConnect(want);
-    }
-    
-    void MyServiceAbility::MsgHandle(uint32_t funcId, IpcIo *request, IpcIo *reply)
-    {
-        printf("ServiceAbility::MsgHandle, funcId is %u\n", funcId);
-        int result = 0;
-        if (funcId == 0) {
-            result = IpcIoPopInt32(request) + IpcIoPopInt32(request);
-        }
-        // push data
-        IpcIoPushInt32(reply, result);
-    }
-    ```
-
-3.  实现Service相关的生命周期方法。Service也是一种Ability，Ability为服务提供了以下生命周期方法，用户可以重写这些方法来添加自己的处理。用户在重写的方法里，需要调用父类对应的方法。
-    -   OnStart\(\)
-
-        该方法在创建Service的时候调用，用于做一些Service初始化且耗时较短的工作，在Service的整个生命周期只会调用一次。
-
-        ```
-        void MyServiceAbility::OnStart(const Want& want)
-        {
-            printf("ServiceAbility::OnStart\n");
-            Ability::OnStart(want);
-        }
-        ```
-
-    -   OnConnect​\(\)
-
-        在组件和服务连接时调用，该方法返回SvcIdentity，组件可以通过它，与服务交互。
-
-        ```
-        const SvcIdentity *MyServiceAbility::OnConnect(const Want &want)
-        {
-            printf("ServiceAbility::OnConnect\n");
-            return Ability::OnConnect(want);
-        }
-        ```
-
-    -   OnDisconnect​\(\)
-
-        在组件与绑定的Service断开连接时调用。
-
-    -   OnStop\(\)
-
-        在Service销毁时调用。Service应通过实现此方法来清理任何资源，如关闭线程、注册的侦听器等。
-
-
-4.  重写消息处理方法。
-
-    MsgHandle是Service用来处理客户端消息的方法。其中funcId是客户端传过来的消息类型，request是客户端传过来的序列化请求参数。如果用户在处理完成之后想要把结果传回去，需要把结果序列化后写入reply中。
-
-    ```
-    void ServiceAbility::MsgHandle(uint32_t funcId, IpcIo *request, IpcIo *reply)
-    {
-        printf("ServiceAbility::MsgHandle, funcId is %d\n", funcId);
-        int result = 0;
-        if (funcId == PLUS) {
-            result = IpcIoPopInt32(request) + IpcIoPopInt32(request);
-        }
-        // push data
-        IpcIoPushInt32(reply, result);
-    }
-    ```
-
-5.  注册Service。
-
-    Service也需要在应用清单文件config.json中进行注册，注册类型type需要设置为service。
-
-    ```
-    "abilities": [{
-        "name": "ServiceAbility",
-        "icon": "res/drawable/phone.png",
-        "label": "test app 2", 
-        "launchType": "standard",
-        "type": "service",
-        "visible": true
-    }
-    ]
-    ```
-
-6.  启动Service。
-    -   Ability为用户提供了StartAbility\(\)方法来启动另外一个Ability，因为Service也是Ability的一种，开发者同样可以通过将Want传递给该方法来启动Service。
-
-        开发者可以通过Want的SetWantElement \(\)来设置目标服务信息。ElementName结构体的两个主要参数：第一个参数为包名称；第二个参数为目标Ability。
-
-        ```
-        {
-            Want want = { nullptr };
-            ElementName element = { nullptr };
-            SetElementBundleName(&element, "com.company.appname");
-            SetElementAbilityName(&element, "ServiceAbility");
-            SetWantElement(&want, element);
-            StartAbility(want);
-            ClearElement(&element);
-            ClearWant(&want);
-        }
-        ```
-
-        StartAbility\(\) 方法会立即执行，如果Service尚未运行，则系统首先会调用OnStart\(\)。
-
-    -   停止Service。
-
-        Service一旦创建就会一直保持在后台运行，开发者可以通过调用StopAbility\(\)来停止Service。
-
-
-7.  连接Service。
-    -   如果Service需要与Page Ability或其他应用组件中的Service进行交互，则应创建用于连接的Service。Service支持其他Ability通过ConnectAbility\(\)与其进行连接，ConnectAbility\(\)需要传入目标Service的Want，以及IAbilityConnection的实例来处理回调。IAbilityConnection提供了两个方法供用户实现，OnAbilityConnectDone\(\)用来处理连接的回调，OnAbilityDisconnectDone\(\)用来处理断开连接的回调。
-
-        ```
-        {
-            // ability创建IAbilityConnection对象和定义IAbilityConnection的两个方法实现
-            IAbilityConnection abilityConnection = new IAbilityConnection();
-            abilityConnection->OnAbilityConnectDone = OnAbilityConnectDone;
-            abilityConnection->OnAbilityDisconnectDone = OnAbilityDisconnectDone;
-         
-            void OnAbilityConnectDone(ElementName *elementName, SvcIdentity *serviceSid, 
-                int resultCode, void *data)
-            {
-                if (resultCode != 0) {
-                    return;
-                }
-                // push data
-                IpcIo request;
-                char dataBuffer[IPC_IO_DATA_MAX];
-                IpcIoInit(&request, dataBuffer, IPC_IO_DATA_MAX, 0);
-                IpcIoPushInt32(&request, 10);
-                IpcIoPushInt32(&request, 6);
-         
-                // send and getReply
-                IpcIo reply;
-                uintptr_t ptr = 0;
-                if (Transact(nullptr, *serviceSid, 0, &request, &reply, 
-                    LITEIPC_FLAG_DEFAULT, &ptr) != LITEIPC_OK) {
-                    printf("transact error\n");
-                    return;
-                }
-                int result = IpcIoPopInt32(&reply);
-                printf("execute add method, result is %d\n", result);
-                if (ptr != 0) {
-                    FreeBuffer(nullptr, reinterpret_cast<void *>(ptr));
-                }
-            }
-         
-            void OnAbilityDisconnectDone(ElementName *elementName, 
-                int resultCode, void *data)
-            {
-                printf("elementName is %s, %s\n", 
-                    elementName->bundleName, elementName->abilityName);
-            }
-        }
-        ```
-
-    -   发起connect和disconnect。
-
-        ```
-        {
-            // ability发起connect
-            Want want = { nullptr };
-            ElementName element = { nullptr };
-            SetElementBundleName(&element, "com.company.appname");
-            SetElementAbilityName(&element, "ServiceAbility");
-            SetWantElement(&want, element);
-            ConnectAbility(want, *abilityConnection, this);
-         
-            // ability发起disconnect
-            DisconnectAbility(*abilityConnection);
-        }
-        ```

-### 包管理接口使用指导<a name="section1724016743217"></a>
-
-**安装应用**
-
-安装接口只能给内置的系统应用使用。根据应用的安装路径，可以在安装应用时进行选择：
-
--   将应用安装到系统默认的文件目录/storage/app/。
--   将应用安装到系统外挂的存储介质中，例如micro sdcard。
-
-这两种选择可以在创建InstallParam实例的时候指定，当InstallParam的成员变量installLocation为 INSTALL\_LOCATION\_INTERNAL\_ONLY时，意味着应用将会被安装到/storage/app/目录下；当InstallParam的成员变量installLocation为INSTALL\_LOCATION\_PREFER\_EXTERNAL时，意味着应用将被安装到存储介质，其安装目录是/sdcard/app/。由于安装应用的过程是异步的，所以需要使用类似信号量的机制来确保安装的回调可以被执行。
-
-安装应用的步骤如下（示例代码以安装到系统目录为例）：
-
-1.  将经过安全签名的应用放置于指定的目录下。
-2.  创建InstallParam实例和信号量。
-
-    ```
-    InstallParam installParam = { 
-    .installLocation = INSTALL_LOCATION_INTERNAL_ONLY, // 安装到系统目录
-    .keepData = false
-    };
-    static sem_t g_sem;
-    ```
-
-3.  定义回调函数。
-
-    ```
-    static void InstallCallback(const uint8_t resultCode, const void *resultMessage)
-    {
-         std::string strMessage = reinterpret_cast<const char *>(resultMessage);
-         if (!strMessage.empty()) {
-            printf("install resultMessage is %s, %d\n", strMessage.c_str(),resultCode);
-         }
-         sem_post(&g_sem);
-    }
-    ```
-
-4.  调用Install接口。
-
-    ```
-    const uint32_t WAIT_TIMEOUT = 30;
-    sem_init(&g_sem, 0, 0);
-    std::string installPath = “/storage/bundle/demo.hap”; // hap包的存储路径
-    bool result = Install(installPath.c_str(), &installParam, InstallCallback);
-    struct timespec ts = {};
-    clock_gettime(CLOCK_REALTIME, &ts);
-    ts.tv_sec += WAIT_TIMEOUT; // 超时即释放信号量
-    sem_timedwait(&g_sem, &ts);
-    ```
-
-
-**卸载应用**
-
-卸载应用的时候可以选择是否保留应用的数据，开发者可以通过创建的InstallParam实例的成员变量keepData来确定。当keepData为true, 卸载应用之后将保留应用的数据，当keepData为false时，卸载应用之后将不会保留应用的数据。
-
-1.  创建InstallParam实例和信号量。
-
-    ```
-    static sem_t g_sem;
-    InstallParam installParam = {
-    .installLocation = 1,
-         .keepData = false // 不保留应用数据
-    };
-    ```
-
-2.  定义回调函数。
-
-    ```
-    static void UninstallCallback(const uint8_t resultCode, const void *resultMessage)
-    {
-        std::string strMessage = reinterpret_cast<const char *>(resultMessage);
-        if (!strMessage.empty()) {
-            printf("uninstall resultMessage is %s\n", strMessage.c_str());
-            g_resultMessage = strMessage;
-        }
-        g_resultCode = resultCode;
-        sem_post(&g_sem);
-    }
-    ```
-
-3.  调用Uninstall接口。
-
-    ```
-    sem_init(&g_sem, 0, 0);
-    const uint32_t WAIT_TIMEOUT = 30;
-    std::string BUNDLE_NAME = “com.huawei.demo”; // 卸载应用的包名
-    Uninstall(BUNDLE_NAME.c_str(), &installParam, UninstallCallback);
-    struct timespec ts = {};
-    clock_gettime(CLOCK_REALTIME, &ts);
-    ts.tv_sec += WAIT_TIMEOUT;
-    sem_timedwait(&g_sem, &ts);
-    ```
-
-
-**查询已安装应用的包信息**
-
-开发者可以利用BundleManager提供的接口GetBundleInfo来查询系统内已安装应用的包信息。
-
-1.  创建以及初始化BundleInfo。
-
-    ```
-    BundleInfo bundleInfo;
-    (void) memset_s(&bundleInfo, sizeof(BundleInfo), 0, sizeof(BundleInfo));
-    ```
-
-2.  调用GetBundleInfo接口，指定查询应用的包名，同时指定flag来确定获取的BundleInfo中是否含有元能力信息（实例代码以含有元能力信息为例）。
-
-    ```
-    std::string BUNDLE_NAME = "com.huawei.demo";
-    uint8_t ret = GetBundleInfo(BUNDLE_NAME.c_str(), 1, &bundleInfo); // flags = 1，获取包信息中含有元能力信息
-    ```
-
-3.  使用完获取的BundleInfo之后，要及时清理掉其内部所占用的内存空间避免内存泄漏。
-
-    ```
-    ClearBundleInfo(&bundleInfo);
-    ```
-

-
-以开发唤醒词识别为例，开发者可在Hi3516DV300开发板上，基于AI引擎框架开发唤醒词识别的sdk以及唤醒词识别的plugin，通过编译命令编出新的版本镜像并将其烧入版本。同时，开发者开发唤醒词识别的应用，该应用能够接收外部音频，将listen到的音频传入SDK中的接口，若音频中带有关键词，唤醒词识别的应用会识别出相应的词语，并打印在命令行中。
-
-本示例中唤醒词识别的场景中唤醒词是固定的，当开发者传入的音频包含”Hi，小问“，启动的应用就会打印"\[Hi, xiaowen\]"，当不包含时，会打印'\[UNKNOWN\]"。

-
-## 开发步骤<a name="section138543918214"></a>
-
-1.  <a name="li378084192111"></a>实现设备状态回调的派生类，用户在设备状态发生变更（如新插入相机设备/相机掉线）时，自定义操作。
-
-    ```
-    class SampleCameraDeviceCallback : public CameraDeviceCallback {
-        void OnCameraStatus(std::string cameraId, int32_t status) override
-        {
-            //do something when camera is available/unavailable
-        }
-    };
-    ```
-
-2.  <a name="li8716104682913"></a>实现帧事件回调的派生类，这里在拿到帧数据以后将其转存为文件。
-
-    ```
-    static void SampleSaveCapture(const char *p, uint32_t size)
-    {
-        cout << "Start saving picture" << endl;
-        struct timeval tv;
-        gettimeofday(&tv, NULL);
-        struct tm *ltm = localtime(&tv.tv_sec);
-        if (ltm != nullptr) {
-            ostringstream ss("Capture_");
-            ss << "Capture" << ltm->tm_hour << "-" << ltm->tm_min << "-" << ltm->tm_sec << ".jpg";
-    
-            ofstream pic("/sdcard/" + ss.str(), ofstream::out | ofstream::trunc);
-            cout << "write " << size << " bytes" << endl;
-            pic.write(p, size);
-            cout << "Saving picture end" << endl;
-        }
-    }
-    
-    class TestFrameStateCallback : public FrameStateCallback {
-        void OnFrameFinished(Camera &camera, FrameConfig &fc, FrameResult &result) override
-        {
-            cout << "Receive frame complete inform." << endl;
-            if (fc.GetFrameConfigType() == FRAME_CONFIG_CAPTURE) {
-                cout << "Capture frame received." << endl;
-                list<Surface *> surfaceList = fc.GetSurfaces();
-                for (Surface *surface : surfaceList) {
-                    SurfaceBuffer *buffer = surface->AcquireBuffer();
-                    if (buffer != nullptr) {
-                        char *virtAddr = static_cast<char *>(buffer->GetVirAddr());
-                        if (virtAddr != nullptr) {
-                            SampleSaveCapture(virtAddr, buffer->GetSize());
-                        }
-                        surface->ReleaseBuffer(buffer);
-                    }
-                    delete surface;
-                }
-                delete &fc;
-            }
-        }
-    };
-    ```
-
-3.  <a name="li6671035102514"></a>实现相机状态回调的派生类，当相机状态发生变化（配置成功/失败，创建成功/失败\)时，自定义操作。
-
-    ```
-    class SampleCameraStateMng : public CameraStateCallback {
-    public:
-        SampleCameraStateMng() = delete;
-        SampleCameraStateMng(EventHandler &eventHdlr) : eventHdlr_(eventHdlr) {}
-        ~SampleCameraStateMng()
-        {
-            if (recordFd_ != -1) {
-                close(recordFd_);
-            }
-        }
-        void OnCreated(Camera &c) override
-        {
-            cout << "Sample recv OnCreate camera." << endl;
-            auto config = CameraConfig::CreateCameraConfig();
-            config->SetFrameStateCallback(&fsCb_, &eventHdlr_);
-            c.Configure(*config);
-            cam_ = &c;
-        }
-        void OnCreateFailed(const std::string cameraId, int32_t errorCode) override {}
-        void OnReleased(Camera &c) override {}
-    };
-    ```
-
-4.  创建CameraKit，用于创建和获取camera信息。
-
-    ```
-    CameraKit *camKit = CameraKit::GetInstance();
-    list<string> camList = camKit->GetCameraIds();
-    string camId;
-    for (auto &cam : camList) {
-        cout << "camera name:" << cam << endl;
-        const CameraAbility *ability = camKit->GetCameraAbility(cam);
-        /* find camera which fits user's ability */
-        list<CameraPicSize> sizeList = ability->GetSupportedSizes(0);
-        if (find(sizeList.begin(), sizeList.end(), CAM_PIC_1080P) != sizeList.end()) {
-            camId = cam;
-            break;
-        }
-    }
-    ```
-
-5.  创建Camera实例。
-
-    ```
-    EventHandler eventHdlr; // Create a thread to handle callback events
-    SampleCameraStateMng CamStateMng(eventHdlr);
-    
-    camKit->CreateCamera(camId, CamStateMng, eventHdlr);
-    ```
-
-6.  根据[步骤1](#li378084192111)、[步骤2](#li8716104682913)、[步骤3](#li6671035102514)中的回调设计，camera实例创建成功后会进行配置操作，主流程中app需要设计同步机制。
-
-    ```
-    void OnCreated(Camera &c) override
-    {
-        cout << "Sample recv OnCreate camera." << endl;
-        auto config = CameraConfig::CreateCameraConfig();
-        config->SetFrameStateCallback(&fsCb_, &eventHdlr_);
-        c.Configure(*config);
-        cam_ = &c;
-    }
-    
-    void Capture()
-    {
-        if (cam_ == nullptr) {
-            cout << "Camera is not ready." << endl;
-            return;
-        }
-        FrameConfig *fc = new FrameConfig(FRAME_CONFIG_CAPTURE);
-        Surface *surface = Surface::CreateSurface();
-        if (surface == nullptr) {
-            delete fc;
-        }
-        surface->SetWidthAndHeight(1920, 1080); /* 1920:width,1080:height */
-        fc->AddSurface(*surface);
-        cam_->TriggerSingleCapture(*fc);
-    }
-    ```

-## 开发步骤<a name="section22501726193214"></a>
-
-1.  实现点击事件。
-
-    ```
-    class TestBtnOnClickListener : public OHOS::UIView::OnClickListener {
-        bool OnClick(UIView& view, const ClickEvent& event) override
-        {
-            int16_t width = view.GetWidth() + 10;
-            int16_t height = view.GetHeight() + 10;
-            view.Resize(width, height);
-            view.Invalidate();
-            return true;
-        }
-    };
-    ```
-
-2.  创建一个UIButton。
-
-    ```
-    UIButton* button = new UIButton();
-    button->SetPosition(50, 50);
-    button->SetWidth(100);
-    button->SetHeight(50);
-    ```
-
-3.  给UIButton注册点击事件回调。
-
-    ```
-    button->SetOnClickListener(new TestBtnOnClickListener());
-    ```
-
-4.  检查Button点击效果如下图所示，Button逐渐变大。

-OpenHarmony安全子系统目前提供给开发者的安全能力主要包含应用可信、权限管理、设备可信。涉及以下几个模块：
-
--   应用验签
-
-    为了确保应用内容的完整性，系统通过应用签名和Profile对应用的来源进行管控，同时对于调试应用，还可通过验签接口验证应用和设备的UDID是否匹配，确保应用安装在了正确的设备上。
-
--   应用权限管理
-
-    应用权限是管理应用访问系统资源和使用系统能力的一种通用方式，应用在开发阶段需要在profile.json中指明此应用在运行过程中可能会调用哪些权限，其中静态权限表示只需要在安装阶段注册就可以，而动态权限一般表示涉及到敏感信息，所以需要用户进行动态授权。
-
--   IPC通信鉴权
-
-    系统服务通过IPC暴露接口给其他进程访问，这些接口需要配置相应的访问策略，当其他进程访问这些接口时，将会触发IPC通信鉴权机制校验访问进程是否拥有权限访问该接口，若无权限，则拒绝访问该接口。
-
--   可信设备群组管理
-
-    提供基于群组概念的同华为账号群组、点对点群组（如二维码、碰一碰等）的设备安全可信关系的创建和查询，分布式应用可基于该能力进行设备间的可信认证，然后向分布式软总线请求设备间安全会话。
-
-
-## 基本概念<a name="section175012297491"></a>
-
-在进行依赖验签组件的应用开发前，开发者应了解以下基本概念：
-
--   Samgr
-
-    Samgr\(System Ability M2anager\)系统能力管理，在OpenHarmony上作为一个管理系统能力的模块，详见系统服务框架子系统。
-
-
--   BMS
-
-    BMS\(Bundle Manager Service\)包管理管理，在OpenHarmony上主要负责应用的安装、卸载和数据管理。
-
-
--   描述文件
-
-    本文中的描述文件，指HarmonyAppProvision，简称profile。HarmonyAppProvision采用json文件格式进行描述。
-
-
--   叶子证书
-
-    最终用于为整包或profile签名的证书称为叶子证书，位于数字证书链的最末端。
-
-
--   调试应用
-
-    指开发者从应用市场申请调试证书与调试描述文件，并以此签名的hap包。
-
-
--   待上架应用
-
-    指开发者从应用市场申请发布证书与发布描述文件，以此签名，未通过应用市场正式发布的hap包。
-
-
--   发布应用
-
-    指开发者从应用市场申请发布证书与发布描述文件，以此签名的hap包，上传至应用市场，并由应用市场正式发布的hap包。
-
-
--   OpenHarmony自签名应用
-
-    当开发者自行编译OpenHarmony系统应用后，采用原应用描述文件，以及公开的OpenHarmony公私钥对和证书进行自签名产生的hap包。
-
-
-## 约束与限制<a name="section2029921310472"></a>
-
--   仅支持以下三类应用的验签：应用市场调试应用、应用市场发布应用、OpenHarmony自签名应用的验签。
--   若对应用市场调试应用验签，则本机UDID需要在描述文件包含的UDID列表中。
--   待上架应用无法验签通过。
--   验签组件提供的接口都位于security\_interfaces\_innerkits\_app\_verify仓[app\_verify\_pub.h](https://gitee.com/fork_ohos_wj/security_interfaces_innerkits_app_verify/blob/master/app_verify_pub.h)中，仅支持系统应用开发者调用。
--   可信设备群组管理接口，目前只对系统签名权限才可以使用。

-用户程序框架是OpenHarmony为开发者提供开发OpenHarmony应用的开发框架，包含两个模块：Ability子系统和包管理子系统。
-
-## 基本概念<a name="section72601941194812"></a>
-
-开发者在开发前需要先了解以下基本概念，方便开发者更好的理解OpenHarmony用户程序框架。
-
-## Ability子系统<a name="section14633111813374"></a>
-
-Ability子系统是管理OpenHarmony应用运行状态的开发框架。
-
-**图 1**  Ability子系统框架图<a name="fig9759195514371"></a>  
-![](figures/Ability子系统框架图.png "Ability子系统框架图")
-
--   **Ability**：系统调度应用的最小单元，是能够完成一个独立功能的组件，一个应用可以包含一个或多个Ability。Ability分为两种类型：Page类型的Ability和Service类型的Ability。
-    -   **Page类型的Ability**：带有界面，为用户提供人机交互的能力。
-
-    -   **Service类型的Ability**：不带界面，为用户提供后台任务机制。
-
-
-
--   **AbilitySlice**：单个页面及其控制逻辑的总和，是Page类型Ability特有的组件，一个Page类型的Ability可以包含多个AbilitySlice，此时，这些页面提供的业务能力应当是高度相关的。
-
-    **图 2**  Ability与AbilitySlice的关系图<a name="fig1065819910347"></a>  
-    ![](figures/Ability与AbilitySlice的关系图.png "Ability与AbilitySlice的关系图")
-
--   **生命周期**：Ability被调度到启动、激活、隐藏和退出等各个状态的统称。
-
-    **图 3**  Ability生命周期流转<a name="fig56111543375"></a>  
-    
-
-    ![](figures/图片1.png)
-
-    -   **OnStart\(\)**
-
-        系统首次创建Page实例时触发该回调。对于一个Page实例，该回调在其生命周期过程中仅触发一次，Page在该逻辑后进入INACTIVE状态。开发者必须重写该方法，并在此配置默认展示的AbilitySlice。
-
-    -   **OnActive\(\)**
-
-        Page会在进入INACTIVE状态后来到前台，然后系统调用此回调。Page在此之后进入ACTIVE状态，该状态是应用与用户交互的状态。Page将保持在此状态，除非某类事件发生导致Page失去焦点，比如用户点击返回键或导航到其他Page。
-
-        当此类事件发生时，会触发Page回到INACTIVE状态，系统将调用OnInactive\(\)回调。此后，Page可能重新回到ACTIVE状态，系统将再次调用OnActive\(\)回调。因此，开发者通常需要成对实现OnActive\(\)和OnInactive\(\)，并在OnActive\(\)中获取在OnInactive\(\)中被释放的资源。
-
-    -   **OnInactive\(\)**
-
-        当Page失去焦点时，系统将调用此回调，此后Page进入INACTIVE状态。开发者可以在此回调中实现Page失去焦点时应表现的恰当行为。
-
-    -   **OnBackground\(\)**
-
-        如果Page不再对用户可见，系统将可能根据资源状况调用此回调，此后Page进入BACKGROUND状态。开发者应该在此回调中释放Page不可见时无用的资源，或在此回调中执行较为耗时的状态保存操作。
-
-    -   **OnForeground\(\)**
-
-        处于BACKGROUND状态的Page仍然驻留在内存中，当重新回到前台时（比如用户重新导航到此Page），系统将先调用OnForeground\(\)回调使Page回到INACTIVE状态，然后调用OnActive\(\)回调使Page回到ACTIVE状态。开发者应当在此回调中重新申请在OnBackground\(\)中释放的资源。轻量化设备目前不支持该接口。
-
-    -   **OnStop\(\)**
-
-        此回调表示系统正在销毁Page。销毁Page的可能原因包括：
-
-        -   用户通过系统管理能力显式关闭Page，例如使用任务管理器关闭Page。
-        -   用户行为触发Page的TerminateAbility\(\)方法调用，例如使用应用的退出功能。
-        -   配置变更导致系统暂时销毁Page并重建。
-        -   系统出于资源管理目的，自动触发对处于BACKGROUND状态Page的销毁。
-
-
--   **AbilityKit**：Ability框架提供给开发者的开发包，开发者基于该开发包可以开发出基于Ability组件的应用。基于Ability组件开发的应用有两种类型：基于Javascript语言开发的Ability（JS Ability）和基于C/C++语言开发的Ability（Native Ability）。JS应用开发框架是开发者开发JS Ability所用到框架，是在AbilityKit基础封装的包含js UI组件的一套方便开发者能够迅速开发Ability应用的框架。
--   **AbilityLoader**：负责注册和加载开发者Ability的模块。开发者开发的Ability先要调用AbilityLoader的注册接口注册到框架中，接着Ability启动时会被实例化。
-
--   **AbilityManager**：负责AbilityKit和Ability管理服务进行IPC的通信。
-
--   **EventHandler**：AbilityKit提供给开发者的用于在Ability中实现线程间通信的一个模块。
-
--   **AbilityManagerService**：元能力运行管理服务。该服务用于协调各Ability运行关系、及生命周期进行调度的系统服务。其中，服务启动模块负责Ability管理服务的启动、注册等。服务接口管理模块负责Ability管理服务对外能力的管理。进程管理模块负责Ability应用所在进程的启动和销毁、及其进程信息维护等功能。Ability栈管理模块负责维护各个Ability之间跳转的先后关系。生命周期调度模块是Ability管理服务根据系统当前的操作调度Ability进入相应的状态的模块。连接管理模块是Ability管理服务对Service类型Ability连接管理的模块
-
--   **AppSpawn**：负责创建Ability应用所在进程的系统服务，该服务有较高的权限，为Ability应用设置相应的权限，并预加载一些通用的模块，加速应用的启动。
-
-
-## 包管理子系统<a name="section1341146154412"></a>
-
-包管理子系统是OpenHarmony为开发者提供的安装包管理框架。
-
-**图 4**  包管理子系统框架图<a name="fig85883251434"></a>  
-![](figures/包管理子系统框架图.png "包管理子系统框架图")
-
--   **BundleKit**：是包管理服务对外提供的接口，有安装/卸载接口、包信息查询接口、包状态变化listen接口。
--   **包扫描器**：用来解析本地预制或者安装的安装包，提取里面的各种信息，供管理子模块进行管理，持久化。
--   **包安装子模块**：安装，卸载，升级一个包；包安装服务是一个单独进程和包管理服务通过IPC进行通信，该服务用于创建、删除安装目录和数据目录等，具有较高的权限。
-
--   **包管理子模块**：管理安装包相关的信息，存储持久化包信息。
-
--   **包安全管理子模块**：签名检查、权限授予、权限管理。
-
-
-## 运作机制<a name="section94302021112717"></a>
-
-Ability子系统的核心模块是Ability管理服务、包管理子系统的核心模块是包管理服务，这两个服务是系统级服务，借助系统服务框架Samgr实现服务的注册与发现，并对其他进程提供Ability管理服务和包管理服务。Ability管理服务和包管理服务通过AbilityKit和BundleKit以接口的形式向外提供服务。
-
-**图 5**  Ability管理服务和包管理服务启动<a name="fig13121104711910"></a>  
-![](figures/Ability管理服务和包管理服务启动.png "Ability管理服务和包管理服务启动")
-
-Ability管理服务和包管理服务启动后，就可以安装OpenHarmony应用和启动运行OpenHarmony应用。
-
-**图 6**  应用启动流程<a name="fig756104112311"></a>  
-![](figures/应用启动流程.png "应用启动流程")
-
-桌面为Ability管理服务启动的第一个OpenHarmony应用。桌面启动后，用户可以在桌面上点击安装的OpenHarmony应用并启动该应用。上图6为从桌面启动一个已安装应用的交互流程。
-
-从图中可知，Ability管理服务负责协调Ability之间的显示隐藏，包管理服务负责Ability信息的存储查询。

-测试子系统提供基于python开发的一键式的开发者自测试平台，支持跨平台使用以及三方测试框架拓展，主要包括测试用例编译、测试用例管理、测试用例调度分发、测试用例执行、测试结果收集、测试报告生成、测试用例模板、测试环境管理等模块。
-
-在测试子系统开发前，开发者应先了解以下概念：
-
--   测试用例编译
-
-    支持将测试用例源代码编译成可在被测设备侧执行的二进制文件。
-
--   测试用例调度分发
-
-    支持将测试用例通过网口通道或者串口通道分发到不同的被测设备上，并且为每一个测试用例分配特定的测试用例执行器。
-
--   测试用例执行器
-
-    负责测试用例的预处理，用例执行，结果记录等执行逻辑。
-
--   测试用例模板
-
-    定义了测试用例以及用例编译配置GN文件的统一格式。
-
--   测试平台kit
-
-    测试平台运行过程中公共方法，如提供测试用例目录向被测设备挂载文件系统，测试用例推送到被测设备，或者从被测设备获取测试结果等操作。
-
--   测试报告生成
-
-    定义开发者自测试报告模板，生成web测试报告。
-
--   测试环境管理
-
-    支持通过USB、串口等方式管理被测设备，功能包括设备发现，设备状态查询等。
-
-
-### 运作机制<a name="section2394431106"></a>
-
--   测试平台架构图如下：
-
-**图 1**  测试平台架构<a name="fig418674910399"></a>  
-![](figures/测试平台架构.png "测试平台架构")
-
--   测试平台运行时序图如下：
-
-**图 2**  测试平台运行时序<a name="fig107203017407"></a>  
-![](figures/测试平台运行时序.png "测试平台运行时序")
-
--   测试平台运行原理
-
-测试平台通过shell脚本启动，以命令行方式支持一系列的测试指令执行，通过命令行输出测试结果。
-
-## 约束与限制<a name="section2029921310472"></a>
-
--   功能使用范围：开发自测试平台仅支持代码级的测试用例开发和验证，如单元测试，模块测试。
--   规格限制：当前测试框架的适用范围仅支持白盒测试。
--   操作限制：一台测试设备上仅支持启动单个测试平台。

-### 开发步骤<a name="section53541946111218"></a>
-
-1.  按照开发者测试用例目录规划定义测试套文件，需要继承testing::Test类，命名以被测特性+Test命名，示例代码路径：test/developertest/examples/lite/cxx\_demo/test/unittest/common/calc\_subtraction\_test.cpp

-
-2.  实现测试套执行过程需要的预处理操作和后处理操作，即实现SetUp和TearDown方法。
-
-    ```
-    void CalcSubtractionTest::SetUpTestCase(void)
-    {
-        // step 1: input testsuite setup step
-    }
-    
-    void CalcSubtractionTest::TearDownTestCase(void)
-    {
-        // step 2: input testsuite teardown step
-    }
-    
-    void CalcSubtractionTest::SetUp(void)
-    {
-        // step 3: input testcase setup step
-    }
-    
-    void CalcSubtractionTest::TearDown(void)
-    {
-        // step 4: input testcase teardown step
-    }
-    ```
-
-3.  针对被测对象的特性编写测试用例，以使用HWTEST\_F为例说明。
-
-    ```
-    /**
-     * @tc.name: integer_sub_001
-     * @tc.desc: Test Calculator
-     * @tc.type: FUNC
-     * @tc.require: AR00000000 SR00000000
-     */
-    HWTEST_F(CalcSubtractionTest, integer_sub_001, TestSize.Level1)
-    {
-        EXPECT_EQ(0, Subtraction(1, 0));
-    }
-    ```
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >-   @tc.name：用例名称，对测试目的简要描述。
-    >-   @tc.desc：描述用例详细描述，包括测试目的、测试步骤、期望结果等。
-    >-   @tc.type：测试属性分类（FUNC、PERF、SECU、RELI）。
-    >-   @tc.require：需求编号或者issue编号，用来将修改与用例关联。

-
-4.  编写用例编译GN文件，其中包括定义用例编译目标，添加编译配置依赖，源文件等，举例说明：
-
-    示例文件路径：test/developertest/examples/lite/cxx\_demo/test/unittest/common/BUILD.gn）。
-
-    ```
-    import("//build/lite/config/test.gni")
-    
-    unittest("CalcSubTest") {
-        output_extension = "bin"
-        sources = [
-            "calc_subtraction_test.cpp"
-        ]
-        include_dirs = []
-        deps = []
-    }
-    ```
-
-5.  将用例编译目标添加到子系统编译配置中，保证用例随版本一起编译，举例说明：
-    1.  支持hdc连接的设备，编译配置示例路径：test/developertest/examples/ohos.build。
-
-        ```
-        {
-          "subsystem": "subsystem_examples",
-          "parts": {
-            "subsystem_examples": {
-              "module_list": [
-                "//test/developertest/examples/detector:detector",
-                ... ...
-              ],
-              "test_list": [
-                "//test/developertest/examples/detector/test:unittest",
-                ... ...
-              ]
-            },
-            ... ...
-        }
-        ```
-
-    2.  仅支持串口的设备，编译配置示例路径：test/developertest/examples/lite/BUILD.gn。
-
-        ```
-        import("//build/lite/config/test.gni")
-        
-        subsystem_test("test") {
-            test_components = []
-            if(ohos_kernel_type == "liteos_riscv") {
-                features += [
-                ]
-            }else if(ohos_kernel_type == "liteos_a") {
-                test_components += [
-                    "//test/developertest/examples/lite/cxx_demo/test/unittest/common:CalcSubTest"
-                ]
-            }
-        }
-        ```
-
-
-6.  编写测试用例资源配置，当测试用例需要使用静态测试资源文件时使用该配置。
-    1.  在部件或者模块的test目录下创建resource目录。
-    2.  在resource目录下创建形态目录，如phone。
-    3.  在设备形态目录下创建一个以模块名命名的文件夹，如testmodule。
-    4.  在模块目录下创建一个ohos\_test.xml文件，文件内容格式如下:
-
-        ```
-        <?xml version="1.0" encoding="UTF-8"?>
-        <configuration ver="2.0">
-            <target name="DetectorFileTest">
-                <preparer>
-                    <option name="push" value="test.txt -> /data/test/resource" src="res"/>
-                </preparer>
-            </target>
-        </configuration>
-        ```
-
-    5.  在测试用例的编译配置文件中定义resource\_config\_file，用来指定对应的资源文件ohos\_test.xml。
-
-        >![](public_sys-resources/icon-note.gif) **说明：** 
-        >如上资源文件功能：将resource目录下的test.txt文件通过hdc push命令推送到被测设备的/data/test/resource目录下。
-
-
-7.  以上步骤完成即完成测试用例编写，即可执行测试用例。
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >-   支持hdc连接的设备，测试用例支持单独编译。
-    >-   仅支持串口连接的设备，在代码根路径下执行编译debug版本的命令，即可编译测试用例。
-    >    测试用例用例的执行详见[测试平台使用](#section76401945124810)。

-## 开发实例<a name="section7477121918136"></a>
-
-测试子系统代码仓提供了完整demo用例，demo用例路径：test/developertest/examples/。以一个减法运算方法编写测试用例举例说明：
-
--   被测代码如下：
-
-    ```
-    static int Subtraction(int a, int b)
-    {
-        return a - b;
-    }
-    ```
-
--   测试用例代码如下：
-
-    ```
-    /**
-     * @tc.name: integer_sub_002
-     * @tc.desc: Verify the Subtraction function.
-     * @tc.type: FUNC
-     * @tc.require: AR00000000 SR00000000
-     */
-    HWTEST_F(CalcSubtractionTest, integer_sub_002, TestSize.Level1)
-    {
-        EXPECT_EQ(1, Subtraction(2, 1));
-    }
-    ```
-
-
-## 测试平台使用<a name="section76401945124810"></a>
-
-1.  （可选）安装xdevice组件。安装xdevice后，xdevice组件可以作为python的扩展包使用。
-
-    打开xdevice安装目录：test/xdevice，执行如下命令：
-
-    ```
-    python setup.py install
-    ```
-
-    安装成功提示如下：
-
-    ```
-    ... ...

-    pyserial 3.4 is already the active version in easy-install.pth
-    Installing miniterm.py script to D:\Programs\Python37\Scripts
-    
-    Using d:\programs\python37\lib\site-packages\pyserial-3.4-py3.7.egg
-    Finished processing dependencies for xdevice==0.0.0
-    ```
-
-2.  修改developertest/config/user\_config.xml 文件配置developertest组件。
-    1.  测试框架通用配置。
-
-        \[build\]    \# 配置测试用例的编译参数，例如：
-
-        ```
-        <build>
-            <example>false</example>
-            <version>false</version>
-            <testcase>true</testcase>
-            ... ...
-        </build>
-        ```
-
-        >![](public_sys-resources/icon-note.gif) **说明：** 
-        >测试用例的编译参数说明如下：
-        >example：是否编译测试用例示例，默认false。
-        >version：是否编译测试版本，默认false。
-        >testcase：是否编译测试用例，默认true。
-
-    2.  支持hdc连接的被测设备。
-
-        \[device\]    \# 配置标签为usb-hdc的环境信息，测试设备的IP地址和hdc映射的端口号，例如：
-
-        ```
-        <device type="usb-hdc">
-            <ip>192.168.1.1</ip>
-            <port>9111</port>
-            <sn></sn>
-        </device>
-        ```
-
-    3.  仅支持串口的被测设备。
-
-        \[board\_info\]    \# 开发板配置信息，例如：
-
-        ```
-        <board_info>
-            <board_series>hispark</board_series>
-            <board_type>taurus</board_type>
-            <board_product>ipcamera</board_product>
-            <build_command>hb build</build_command>
-        </board_info>
-        ```
-
-        >![](public_sys-resources/icon-note.gif) **说明：** 
-        >开发板配置信息如下：
-        >board\_series：开发板系列，默认hispark。
-        >board\_type：开发板类型，默认taurus。
-        >board\_product：目标产品，默认ipcamera。
-        >build\_command：测试版本和用例的编译命令，默认hb build。
-
-        \[device\]    \# 配置标签为ipcamera的串口信息，COM口和波特率，例如：
-
-        ```
-        <device type="com" label="ipcamera">
-            <serial>
-                <com>COM1</com>
-                <type>cmd</type>
-                <baud_rate>115200</baud_rate>

-                <timeout>1</timeout>
-            </serial>
-        </device>
-        ```
-
-
-3.  （可选）修改developertest组件配置。如果测试用例已完成编译，可以直接指定测试用例的编译输出路径，测试平台执行用例时即不会重新编译测试用例。
-
-    配置文件：config/user\_config.xml
-
-    1.  \[test\_cases\]    \# 指定测试用例的输出路径，编译输出目录，例如：
-

-        ```
-        <NFS>
-            <host_dir>D:\nfs</host_dir>
-            <board_dir>user</board_dir>
-        </NFS>
-        ```
-
-
-4.  （可选）测试环境准备。当被测设备仅支持串口时，需要检查。
-    -   系统镜像与文件系统已烧录进开发板，开发板上系统正常运行，在系统模式下，如使用shell登录时，设备提示符是“OHOS\#”。
-    -   开发主机和开发板串口连接正常，网口连接正常。
-    -   开发主机IP与开发板IP处在同一小网网段，相互可以ping通。
-    -   开发主机侧创建空目录用于开发板通过NFS挂载测试用例，并且NFS服务启动正常。
-
-5.  （必选）启动测试平台，执行测试用例。
-    -   启动测试框架，打开test/developertest目录，执行启动脚本。
-        1.  Windows环境启动测试框架，执行如下脚本：
-
-            ```

-## 基本概念<a name="section175012297491"></a>
-
-相机是OpenHarmony多媒体进程提供的服务之一，提供了相机的录像、预览、拍照功能，支持多用户并发取流。
-
-在进行应用的开发前，开发者应了解以下基本概念：
-
--   视频帧
-
-    视频流指的是将一系列图片数据按照固定时间间隔排列形成的数据流，每一张图片数据成为一帧，这样的一帧称为视频帧。
-
--   帧速率\(FPS: Frames Per Second\)
-
-    视频播放每秒钟刷新图片的速度，或是视频每秒的帧数，帧速率越高，视频的观感越流畅。
-
--   分辨率
-
-    每一帧的图片信息都是由像素点组成的，分辨率描述了一张图片中像素点的个数。例如1920\*1080\(1080P\)，是指图片宽1920像素，高1080像素。
-
-
-## 运作机制<a name="section193961322175011"></a>
-
--   多媒体服务进程
-
-    多媒体服务作为系统服务，在系统启动时由Init进程拉起，并初始化和分配媒体硬件资源（内存/显示硬件/图像传感器/编解码器等）。初始化过程解析配置文件，确定了多媒体各个服务的能力和资源上限，通常由OEM厂商通过配置文件进行配置。相机服务在多媒体进程初始化时有以下配置项：
-
-    -   内存池：所有媒体服务依赖于内存池中的内存轮转运行
-    -   图像传感器：包括了传感器类型、分辨率、ISP等
-    -   图像处理器：分辨率、码率、图像翻转等
-    -   图像编码器：编码格式、码率、分辨率等
-
-
--   关键类的解释
-
-    应用通过持有下面4个类，配置和使用Camera的功能，包括了Camera类和它的三个异步回调类，三类回调分别对应了不同类型的异步处理场景，详见[表1](#table486418149411)。

--   流的传递
-
-    Surface是多媒体传递音视频的基本数据结构，Camera一般作为Surface中数据的生产者，在不同的场景下有特定的消费者。
-
-    相机的预览和录像输出均为视频流，拍照输出为图像帧，二者均通过Surface类进行传递。Surface类可以屏蔽进程内/跨进程的场景，进行多媒体信息流的传递。
-
-    以录像为例，用户首先创建Recorder实例，并从Recorder中获取对应Surface，再将此Surface传递给Camera实例，此时Camera将作为生产者向Surface注入视频流，而Recorder作为消费者从Surface中取出视频流进行保存，用户的行为类似桥接，把二者通过Surface连接起来。
-
-    类似的，用户也可以自行创建Surface传递给Camera实例，并实现消费者逻辑（例如通过网络传输视频流，或是将拍照的帧数据保存成图片文件）。
-
-    图形图像模块也通过Surface从Camera获取流资源，具体步骤详见[图形图像开发指导](图形图像概述.md)。
-
--   相机运行流程
-    1.  Camera创建流程
-
-        本进程通过CameraManager创建Camera实例，并从服务端绑定camera设备，创建成功后异步通知developer。类之间的时序图如下：

-
-
-    1.  Camera录像/预览流程
-
-        开发者首先通过CameraKit创建Camera，然后FrameConfig类对录像或者预览帧属性进行配置。录像/预览时序如下：

-
-## 开发步骤<a name="section4207112818418"></a>
-
-1.  添加组件。
-
-    本节以添加一个自定义的组件为例，描述如何编译组件，编译库、编译可执行文件等。
-
-    示例组件partA由feature1、feature2和feature3组成，feature1的编译目标为一个动态库，feature2的目标为一个可执行程序，feature3的目标为一个etc配置文件。
-
-    示例组件partA的配置需要添加到一个子系统中，本次示例将添加到subsystem\_examples子系统中（subsystem\_examples子系统定义在test/examples/目录）。
-
-    示例组件partA的完整目录结构如下：
-
-    ```
-    test/examples/partA
-    ├── feature1
-    │   ├── BUILD.gn
-    │   ├── include
-    │   │   └── helloworld1.h
-    │   └── src
-    │       └── helloworld1.cpp
-    ├── feature2
-    │   ├── BUILD.gn
-    │   ├── include
-    │   │   └── helloworld2.h
-    │   └── src
-    │       └── helloworld2.cpp
-    └── feature3
-        ├── BUILD.gn
-        └── src
-            └── config.conf
-    ```
-
-    示例1：编写动态库gn脚本test/examples/partA/feature1/BUILD.gn，示例如下：
-
-    ```
-    config("helloworld_lib_config") {
-     include_dirs = [ "include" ]
-    }
-    
-    ohos_shared_library("helloworld_lib") {
-      sources = [
-        "include/helloworld1.h",
-        "src/helloworld1.cpp",
-      ]
-      public_configs = [ ":helloworld_lib_config" ]
-      part_name = "partA"
-    }
-    ```
-
-    示例2：编写可执行文件gn脚本test/examples/partA/feature2/BUILD.gn，示例如下：
-
-    ```
-    ohos_executable("helloworld_bin") {
-      sources = [
-        "src/helloworld2.cpp"
-      ]
-      include_dirs = [ "include" ]
-      deps = [                                # 依赖组件内模块
-        "../feature1:helloworld_lib"
-      ]
-      external_deps = [ "partB:module1" ]     # （可选）如果有跨组件的依赖，格式为“组件名:模块名”
-      install_enable = true                   # 可执行程序缺省不安装，需要安装时需要指定
-      part_name = "partA"
-    }
-    ```
-
-    示例3：编写etc模块gn脚本test/examples/partA/feature3/BUILD.gn，示例如下：
-
-    ```
-    ohos_prebuilt_etc("feature3_etc") {
-      source = "src/config.conf"
-      relative_install_dir = "init"    #可选，模块安装相对路径，相对于默认安装路径；默认在/system/etc目录
-      part_name = "partA"
-    }
-    ```
-
-    示例4：在子系统的ohos.build中添加组件配置：test/examples/ohos.build。每个子系统有一个ohos.build配置文件，在子系统的根目录下。示例如下：
-
-    ```
-    "partA": {
-        "module_list": [
-          "//test/examples/partA/feature1:helloworld_lib",
-          "//test/examples/partA/feature2:helloworld_bin",
-          "//test/examples/partA/feature3:feature3_etc",
-        ],
-        "inner_kits": [
-    
-        ],
-        "system_kits": [
-    
-        ],
-        "test_list": [
-    
-        ]
-      }
-    ```
-
-    一个组件包含module\_list、inner\_kits、system\_kits、test\_list四个部分的声明，其中：
-
-    -   module\_list：组件所包含的模块列表；
-    -   inner\_kits：组件提供给其它组件调用的接口，其他组件的模块可以在external\_deps中添加依赖的模块；
-    -   system\_kits：组件提供给开发者开发应用的接口；
-    -   test\_list：组件中对应模块的测试用例；
-
-2.  将组件添加到产品配置中。
-
-    在产品的配置中添加组件，产品对应的配置文件：productdefine/common/products/\{product-name\}.json。
-
-    在产品配置文件中添加 "subsystem\_examples:partA"，表示该产品中会编译并打包partA到版本中。
-
-3.  编译。
-
-    以编译Hi3516DV300为例，编译命令如下：
-
-    ```
-    ./build.sh --product-name Hi3516DV300 --ccache
-    ```
-
-4.  编译输出。
-
-    编译所生成的文件都归档在out/ohos-arm-release/目录下，结果镜像输出在 out/ohos-arm-release/packages/phone/images/ 目录下。

-
-## 前提条件<a name="section13333171022312"></a>
-
-开发环境需安装gn、ninja构建工具、python 3.7.4及以上和hb。安装方法请见[搭建系统基础环境](../quick-start/搭建系统环境.md)。
-
-## hb命令行工具使用<a name="section477242204612"></a>
-
-hb是OpenHarmony的命令行工具，用来执行编译命令。以下对hb的常用命令进行说明。
-
-1.  **hb set**
-
-    ```
-    hb set -h
-    usage: hb set [-h] [-root [ROOT_PATH]] [-p]
-    
-    optional arguments:
-      -h, --help            show this help message and exit
-      -root [ROOT_PATH], --root_path [ROOT_PATH]
-                            Set OHOS root path
-      -p, --product         Set OHOS board and kernel
-    ```
-
-    -   hb set 后无参数，进入默认设置流程
-    -   hb set -root dir可直接设置代码根目录
-    -   hb set -p设置要编译的产品
-
-2.  **hb env**
-
-    查看当前设置信息
-
-    ```
-    hb env
-    [OHOS INFO] root path: xxx
-    [OHOS INFO] board: hispark_taurus
-    [OHOS INFO] kernel: liteos
-    [OHOS INFO] product: ipcamera
-    [OHOS INFO] product path: xxx/vendor/hisilicon/ipcamera
-    [OHOS INFO] device path: xxx/device/hisilicon/hispark_taurus/sdk_linux_4.19
-    ```
-
-3.  **hb build**
-
-    ```
-    hb build -h
-    usage: hb build [-h] [-b BUILD_TYPE] [-c COMPILER] [-t [TEST [TEST ...]]]
-                    [--dmverity] [-p PRODUCT] [-f] [-n]
-                    [component [component ...]]
-    
-    positional arguments:
-      component             name of the component
-    
-    optional arguments:
-      -h, --help            show this help message and exit
-      -b BUILD_TYPE, --build_type BUILD_TYPE
-                            release or debug version
-      -t [TEST [TEST ...]], --test [TEST [TEST ...]]
-                            compile test suit
-      --dmverity            Enable dmverity
-      -p PRODUCT, --product PRODUCT
-                            build a specified product with
-                            {product_name}@{company}, eg: ipcamera@hisilcon
-      -f, --full            full code compilation
-      -T [TARGET [TARGET ...]], --target [TARGET [TARGET ...]]
-                            Compile single target
-    ```
-
-    -   hb build后无参数，会按照设置好的代码路径、产品进行编译，编译选项使用与之前保持一致。-f 选项将删除当前产品所有编译产品，等同于hb clean + hb build.
-    -   hb build \{component\_name\}：基于设置好的产品对应的单板、内核，单独编译组件（e.g.：hb build kv\_store\)。
-    -   hb build -p ipcamera@hisilicon：免set编译产品，该命令可以跳过set步骤，直接编译产品。
-    -   在device/device\_company/board下单独执行hb build会进入内核选择界面，选择完成后会根据当前路径的单板、选择的内核编译出仅包含内核、驱动的镜像。
-
-4.  **hb clean**
-
-    清除out目录对应产品的编译产物，仅保留args.gn、build.log。清除指定路径可输入路径参数：hb clean out/board/product，默认将清除当前hb set的产品对应out路径。
-
-    ```
-    hb clean
-    usage: hb clean [-h] [out_path]
-    
-    positional arguments:
-      out_path    clean a specified path.
-    
-    optional arguments:
-      -h, --help  show this help message and exit
-    ```
-
-
-## 新增组件<a name="section4207112818418"></a>
-
-本小节介绍如何新增一个组件，首先确定组件归属的子系统和组件名称，然后按如下步骤新增：
-
-1.  源码开发完成后，添加组件编译脚本。
-
-    以编译组件hello\_world可执行文件为例，applications/sample/hello\_world/BUILD.gn可以写为：
-
-    ```
-    executable("hello_world") {
-      include_dirs = [
-        "include",
-       ]
-      sources = [
-        "src/hello_world.c"
-      ]
-    }
-    ```
-
-    如上编译脚本，可编译出一个可在OpenHarmony上运行的名为hello\_world的可执行文件。
-
-    单独编译该组件，hb set任意选择一款产品，然后使用-T选项单独编译组件：
-
-    ```
-    hb build -f -T //applications/sample/hello_world
-    ```
-
-    组件在开发板上功能验证完成后，可按步骤2\~5将组件配置到产品中。
-
-2.  添加组件描述。
-
-    组件描述位于build/lite/components下，新增的组件需加入对应子系统的json文件中。一个组件描述必选的字段有：
-
-    -   component：组件名称。
-    -   description：组件的一句话功能描述。
-    -   optional：组件是否为系统可选。
-    -   dirs：组件源码路径。
-    -   targets：组件编译入口。
-
-    以将hello\_world组件加入应用子系统为例，在applications.json中添加hello\_world对象：
-
-    ```
-    {
-      "components": [
-        {
-          "component": "hello_world",
-          "description": "Hello world.",
-          "optional": "true",
-          "dirs": [
-            "applications/sample/hello_world"
-          ],
-          "targets": [
-            "//applications/sample/hello_world"
-          ]
-        },
-        ...
-       ]
-    }
-    ```
-
-3.  将组件配置到产品。
-
-    产品的配置文件config.json位于位于vendor/company/product/下，产品配置文件需包含产品名称、OpenHarmony版本号、device厂商、开发板、内核类型、内核版本号，以及配置的子系统和组件。以将hello\_world组件加入产品配置文件my\_product.json中为例，加入hello\_wolrd对象：
-
-    ```
-    {
-        "product_name": "hello_world_test",
-        "ohos_version": "OpenHarmony 1.0",
-        "device_company": "hisilicon",
-        "board": "hispark_taurus",
-        "kernel_type": "liteos_a",
-        "kernel_version": "1.0.0",
-        "subsystems": [
-          {
-            "subsystem": "applications",
-            "components": [
-              { "component": "hello_world", "features":[] }
-            ]
-          },
-          ...
-        ]
-    }
-    ```
-
-4.  编译产品。
-
-    1. 代码根目录输入hb set选择对应产品。
-
-    2. 执行hb build。
-
-
-## 新增芯片解决方案<a name="section2737141421917"></a>
-
-编译构建支持添加新的芯片解决方案厂商，具体步骤如下：
-
-1.  创建芯片解决方案目录。
-
-    按照[芯片解决方案配置规则](编译构建概述.md#section1625463413327)创建目录，以芯片厂商realtek的“rtl8720“开发板为例, 在代码根目录执行：
-
-    ```
-    mkdir -p device/realtek/rtl8720
-    ```
-
-2.  创建内核适配目录，并编写开发板编译配置config.gni文件。
-
-    以realtek的“rtl8720“开发板的liteos\_m适配为例，device/realtek/rtl8720/liteos\_a/config.gni的内容如下：
-
-    ```
-    # Kernel type, e.g. "linux", "liteos_a", "liteos_m".
-    kernel_type = "liteos_a"
-    
-    # Kernel version.
-    kernel_version = "3.0.0"
-    
-    # Board CPU type, e.g. "cortex-a7", "riscv32".
-    board_cpu = "real-m300"
-    
-    # Board arch, e.g. "armv7-a", "rv32imac".
-    board_arch = ""
-    
-    # Toolchain name used for system compiling.
-    # E.g. gcc-arm-none-eabi, arm-linux-harmonyeabi-gcc, ohos-clang, riscv32-unknown-elf.
-    # Note: The default toolchain is "ohos-clang". It's not mandatory if you use the default toochain.
-    board_toolchain = "gcc-arm-none-eabi"
-    
-    # The toolchain path instatlled, it's not mandatory if you have added toolchian path to your ~/.bashrc.
-    board_toolchain_path =
-        rebase_path("//prebuilts/gcc/linux-x86/arm/gcc-arm-none-eabi/bin",
-                    root_build_dir)
-    
-    # Compiler prefix.
-    board_toolchain_prefix = "gcc-arm-none-eabi-"
-    
-    # Compiler type, "gcc" or "clang".
-    board_toolchain_type = "gcc"
-    
-    # Board related common compile flags.
-    board_cflags = []
-    board_cxx_flags = []
-    board_ld_flags = []
-    ```
-
-3.  编写编译脚本。
-
-    在开发板目录下创建BUILD.gn，target名称应与开发板名称一致。以realtek的rtl8720开发板为例，device/realtek/rtl8720/BUILD.gn内容可以是：
-
-    ```
-    group("rtl8720") { # target类型也可以shared_library, static_library, executable
-      # 具体内容
-      ......
-    }
-    ```
-
-4.  编译芯片解决方案。
-
-    在开发板目录下执行hb build，即可启动芯片解决方案的编译。
-
-
-## 新增产品解决方案<a name="section720881917199"></a>
-
-编译构建支持芯片解决方案和组件的灵活拼装，形成定制化的产品解决方案。具体步骤如下：
-
-1.  创建产品目录
-
-    按照[产品解决方案配置规则](编译构建概述.md#section1625463413327)创建产品目录，以基于“rtl8720“开发板的wifiiot模组为例，在代码根目录执行：
-
-    ```
-    mkdir -p vendor/my_company/wifiiot
-    ```
-
-2.  拼装产品
-
-    在新建的产品目录下新建config.json文件，以步骤1中的wifiiot为例，vendor/my\_company/wifiiot/config.json可以是：
-
-    ```
-    {
-        "product_name": "wifiiot",                        # 产品名称
-        "ohos_version": "OpenHarmony 1.0",                # 使用的OS版本
-        "device_company": "realtek",                      # 芯片解决方案厂商名称
-        "board": "rtl8720",                               # 开发板名称
-        "kernel_type": "liteos_m",                        # 选择的内核类型
-        "kernel_version": "3.0.0",                        # 选择的内核版本
-        "subsystems": [                            
-          {
-            "subsystem": "kernel",                        # 选择的子系统
-            "components": [
-              { "component": "liteos_m", "features":[] }  # 选择的组件和组件特性
-            ]
-          },
-          ...
-          {
-             更多子系统和组件
-          }
-        ]
-    }
-    ```
-
-    注意：编译构建系统编译前会对device\_company，board，kernel\_type，kernel\_version、subsystem、component字段进行有效性检查，其中device\_company，board，kernel\_type，kernel\_version应与已知的芯片解决方案匹配，subsystem、component应与build/lite/components下的组件描述匹配。
-
-3.  适配OS接口
-
-    在产品目录下创建hals目录，并将产品解决方案对OS适配的源码和编译脚本放入该目录下。
-
-4.  配置系统服务
-
-    在产品目录下创建init\_configs目录，并在init\_configs目录下创建init.cfg文件，按需配置要启动的系统服务。
-
-5.  配置init进程（仅linux内核需要）
-
-    在init\_configs目录下创建etc目录，然后在etc下创建init.d文件夹和fstab文件。最后按产品需求在init.d文件下创建并编辑rcS文件和Sxxx文件。
-
-6.  配置文件系统镜像（可选，仅支持文件系统的开发板需要）
-
-    在产品目录下创建fs.yml文件。fs.yml需按产品实际情况配置，一个典型的fs.yml文件如下：
-
-    ```
-    -
-      fs_dir_name: rootfs # 镜像的名称
-      fs_dirs:
-        -
-          # 将编译生成的out/my_board/my_product/bin目录下的文件拷贝到rootfs/bin中，并忽略测试bin
-          source_dir: bin
-          target_dir: bin
-          ignore_files:
-            - Test.bin
-            - TestSuite.bin
-        -
-          # 将编译生成的out/my_board/my_product/libs目录下的文件拷贝到rootfs/lib中，忽略所有.a文件，并设置文件和文件夹的权限为644和755
-          source_dir: libs
-          target_dir: lib
-          ignore_files:
-            - .a
-          dir_mode: 755
-          file_mode: 644
-        -
-          source_dir: usr/lib
-          target_dir: usr/lib
-          ignore_files:
-            - .a
-          dir_mode: 755
-          file_mode: 644
-        -
-          source_dir: config

-        -
-          source_dir: sbin
-          target_dir: sbin
-        -
-          source_dir: usr/bin
-          target_dir: usr/bin
-        -
-          source_dir: usr/sbin
-          target_dir: usr/sbin
-        -
-          # 创建一个proc空目录
-          target_dir: proc
-        -
-          target_dir: mnt
-        -
-          target_dir: opt
-        -
-          target_dir: tmp
-        -
-          target_dir: var
-        -
-          target_dir: sys
-        -

-        -
-          file_dir: lib/ld-uClibc-0.9.33.2.so
-          file_mode: 555
-        -
-          file_dir: lib/ld-2.24.so

-        -
-          file_dir: etc/init.cfg
-          file_mode: 400
-      fs_symlink:
-        -
-          # 在rootfs/lib下创建软连接ld-musl-arm.so.1 -> libc.so
-          source: libc.so
-          link_name: ${fs_dir}/lib/ld-musl-arm.so.1
-        -
-          source: mksh
-          link_name: ${fs_dir}/bin/sh
-        -
-          source: mksh

-      fs_make_cmd:
-        - ${root_path}/build/lite/make_rootfs/rootfsimg_linux.sh ${fs_dir} ext4
-    
-    ```
-
-7.  编写编译脚本
-
-    在产品目录下创建BUILD.gn文件，按产品实际情况编写脚本。以步骤1中的wifiiot为例，BUILD.gn示例如下：
-
-    ```
-    group("wifiiot") { # target名称与产品名一致
-      deps = []
-      # 拷贝init配置
-      deps += [ "init_configs" ]
-      # 将hals加入编译
-      deps += [ "hals" ]
-      # 其他
-      ......
-    }
-    ```
-
-8.  编译产品。
-
-    在代码根目录执行hb set按提示选择新增的产品，然后执行hb build即可启动编译。

-
-**图 1**  编译构建流程<a name="fig9744112715161"></a>  
-![](figures/编译构建流程.jpg "编译构建流程")
-
-1.  hb set: 设置OpenHarmony源码目录和要编译的产品。
-2.  hb build: 编译产品、开发板或者组件。编译主要过程如下：
-    -   读取编译配置：根据产品选择的开发板，读取开发板config.gni文件内容，主要包括编译工具链、编译链接命令和选项等。
-    -   调用gn：调用gn gen命令，读取产品配置生成产品解决方案out目录和ninja文件。
-    -   调用ninja：调用ninja -C out/board/product启动编译。
-    -   系统镜像打包：将组件编译产物打包，设置文件属性和权限，制作文件系统镜像。
-
-
-## 组件、芯片解决方案和产品解决方案配置规则<a name="section1625463413327"></a>
-
-为了实现芯片解决方案、产品解决方案与OpenHarmony是解耦的、可插拔的，组件、芯片解决方案和产品解决方案的路径、目录树和配置需遵循一定的规则，具体如下：
-
--   **组件**
-
-组件源码路径命名规则为：_\{领域\}/\{子系统\}/\{组件\}_，组件目录树规则如下：
-
-```
-component
-├── interfaces
-│   ├── innerkits  # 系统内接口，组件间使用
-│   └── kits       # 应用接口，应用开发者使用
-├── frameworks     # framework实现
-├── services       # service实现
-└── BUILD.gn       # 组件编译脚本
-```
-
-组件的名称、源码路径、功能简介、是否必选、编译目标、RAM、ROM、编译输出、已适配的内核、可配置的特性和依赖等属性定义在build/lite/components目录下对应子系统的json文件中，新增组件时需要在对应子系统json文件中添加相应的组件定义。产品所配置的组件必须在某个子系统中被定义过，否则会校验失败。
-
-以泛sensor子系统的sensor服务组件为例，组件属性定义描述文件字段说明如下：
-
-```
-{
-  "components": [
-    {
-      "component": "sensor_lite",                # 组件名称
-      "description": "Sensor services",          # 组件一句话功能描述
-      "optional": "true",                        # 组件是否为最小系统必选
-      "dirs": [                                  # 组件源码路径
-        "base/sensors/sensor_lite"

-      "targets": [                               # 组件编译入口

-      ],
-      "rom": "92KB",                             # 组件ROM值
-      "ram": "~200KB",                           # 组件RAM估值
-      "output": [ "libsensor_frameworks.so" ],   # 组件编译输出

-组件的编译脚本语言为gn，gn的基本用法请见[gn快速入门](https://gn.googlesource.com/gn/+/master/docs/quick_start.md)。组件即为gn定义的编译目标，可以为静态库、动态库、可执行文件或group。组件BUILD.gn的编写建议如下：
-
-1）编译目标名称与组件一致。
-
-2）组件对外可配置的特性变量需声明在该组件BUILD.gn中，特性变量命名规则：ohos\_\{subsystem\}\_\{component\}\_\{feature\}。特性在组件描述中也需要同步定义，在产品配置文件config.json中按需配置。
-
-3）宏定义规则：OHOS\_\{SUBSYSTEM\}\_\{COMPONENT\}\_\{FEATURE\}
-
-以图形的UI组件为例，foundation/graphic/ui/BUILD.gn文件如下：
-
-```
-	# 声明组件可配置的特性
-	declare_args() {
-	  enable_ohos_graphic_ui_animator = false # 动效特性开关
-	  ohos_ohos_graphic_ui_font = "vector"    # 可配置的字体类型，vector或者bitmap
-	}
-	
-	# 组件基础功能
-	shared_library("base") {
-	  sources = [
-	    ......
-	  ]
-	  include_dirs = [
-	    ......
-	  ]
-	}
-	
-	# 仅在animator开启时编译
-	if(enable_ohos_graphic_ui_animator ) { 
-	  shared_library("animator") {
-	    sources = [
-	      ......
-	    ]
-	    include_dirs = [
-              ......
-	    ]
-	    deps = [ :base ]
-	  }
-	}
-	......
-	# target名称建议与组件名称一致, 组件target类型可以是executable(bin文件)，shared_library(动态库.so)，static_library(静态库.a)，group等等
-	executable("ui") {
-	  deps = [
-	    ":base"
-	  ]
-
-	  # animator特性由产品配置
-	  if(enable_ohos_graphic_ui_animator ) {
-	      deps += [
-	        "animator"
-	      ]
-	  }
-	}

--   **芯片解决方案**
-
-芯片解决方案是指基于某款开发板的完整解决方案，包含驱动、设备侧接口适配、开发板sdk等。芯片解决方案是一个特殊的组件，源码路径规则为：_device/\{芯片解决方案厂商\}/\{开发板\}_。芯片解决方案组件会随产品选择的开发板默认编译。芯片解决方案目录树规则如下：
-
-```
-device                                      
-└── company                         # 芯片解决方案厂商
-    └── board                       # 开发板名称
-        ├── BUILD.gn                # 编译脚本
-        ├── hals                    # OS南向接口适配
-        ├── linux                   # 可选，linux内核版本
-        │   └── config.gni          # linux版本编译配置
-        └── liteos_a                # 可选，liteos内核版本
-            └── config.gni          # liteos_a版本编译配置
-```
-
-config.gni为开发板编译相关的配置。编译时会采用该配置文件中的参数选择编译相应的OS组件，编译阶段系统全局可见。关键字段介绍如下：
-
-```
-kernel_type:            开发板使用的内核类型，例如：“liteos_a”, “liteos_m”, “linux”。
-kernel_version:         开发使用的内核版本，例如：“4.19”。
-board_cpu:              开发板CPU类型，例如：“cortex-a7”, “riscv32”。
-board_arch:             开发芯片arch, 例如： “armv7-a”, “rv32imac”。
-board_toolchain:        开发板自定义的编译工具链名称，例如：“gcc-arm-none-eabi”。若为空，则使用默认为ohos-clang。
-board_toolchain_prefix：编译工具链前缀，例如：“gcc-arm-none-eabi”。
-board_toolchain_type：  编译工具链类型，目前支持gcc和clang。例如：“gcc” ，“clang”。
-board_cflags：          开发板配置的c文件编译选项。
-board_cxx_flags：       开发板配置的cpp文件编译选项。
-board_ld_flags：        开发板配置的链接选项。
-```
-
--   **产品解决方案**
-
-产品解决方案为基于开发板的完整产品，主要包含产品对OS的适配、组件拼装配置、启动配置和文件系统配置等。源码路径规则为：_vendor/\{产品解决方案厂商\}/\{产品名称\}。_产品解决方案也是一个特殊的组件，目录树规则如下：
-
-```
-vendor                              
-└── company                         # 产品解决方案厂商
-    ├── product                     # 产品名称
-    │   ├── init_configs
-    │   │     ├── etc               # init进程启动配置（可选，仅linux内核需要）
-    │   │     └── init.cfg          # 系统服务启动配置
-    │   ├── hals                    # 产品解决方案OS适配
-    │   ├── BUILD.gn                # 产品编译脚本
-    │   └── config.json             # 产品配置文件
-    │   └── fs.yml                  # 文件系统打包配置
-    └── ......
-```
-
-新增产品须按如上的规则创建目录和文件，编译构建系统将按该规则扫描已配置的产品。关键的目录和文件详细介绍如下：
-
-1.  vendor/company/product/init\_configs/etc
-
-    该文件夹中包含rcS脚本，Sxxx脚本和fstab脚本，init进程在启动系统服务之前执行这些脚本。执行的流程为“rcS-\>fstab-\>S00-xxx“，Sxxx脚本中的内容与开发板和产品需要有关，主要包括设备节点的创建、创建目录、扫描设备节点、修改文件权限等等。这些文件在产品编译的BUILD.gn中按需拷贝到产品out目录中，最终打包到rootfs镜像中。
-
-2.  vendor/company/product/init\_configs/init.cfg
-
-    init进程启动服务的配置文件，当前支持解析的命令有：
-
-    1\) start:  启动某个服务
-
-    2\) mkdir: 创建文件夹
-
-    3）chmod: 修改指定路径/文件的权限
-
-    4\) chown: 修改指定路径/文件的属组
-
-    5\) mount: 挂载命令
-
-    该文件中的各个字段的解释如下：
-
-    ```
-    {
-        "jobs" : [{                                                     # job数组，一个job对应一个命令集合。job的执行顺序：pre-init -> init -> post-init。

-                    "mkdir /storage/data/log",
-                    "chmod 0755 /storage/data/log",
-                    "chown 4 4 /storage/data/log",                      # 修改属组，第一个数字为uid, 第二个数字为gid
-                    ......
-                    "mount vfat /dev/mmcblock0 /sdcard rw,umask=000"    # 挂载，格式为： mount [文件系统类型] [source] [target] [flags] [data]

-                    ......
-                    "start service1"
-                ]
-            }, {
-                "name" : "post-init",                                   # 最后别执行的job, init进程启动完成后的处理（如驱动初始化后再mount设备）

-            }
-        ],
-        "services" : [{                                                 # service数组，一个service对应一个进程

-        ]
-    }
-    ```
-
-3.  vendor/company/product/init\_configs/hals
-
-    解决方案厂商对OS的适配，需要实现的接口请见各个组件的readme说明文档。
-
-4.  vendor/company/product/config.json
-
-    config.json为编译构建的主入口，包含了开发板、OS组件和内核等配置信息。以基于hispark\_taurus开发板的ipcamera产品为例，配置文件如下：
-
-    ```
-    {
-    	"product_name": "ipcamera",                       # 产品名称
-    	"ohos_version": "OpenHarmony 1.0",                # 选择的OS版本
-    	"device_company": "hisilicon",                    # 芯片厂商
-    	"board": "hispark_taurus",                        # 开发板名称
-    	"kernel_type": "liteos_a",                        # 选择的内核类型
-    	"kernel_version": "3.0.0",                        # 选择的内核版本
-    	"subsystems": [                            
-    	  {
-    	    "subsystem": "aafwk",                         # 选择的子系统
-    	    "components": [
-    	      { "component": "ability", "features":[ "enable_ohos_appexecfwk_feature_ability = true" ] }   # 选择的组件和组件特性配置
-    	    ]
-    	  },
-    	  {
-    	   ......
-    	  }
-    	  ......
-    	  更多子系统和组件
-    	}
-    }
-    ```
-
-5.  vendor/company/product/fs.yml
-
-    该文件用于配置文件系统镜像制作过程，将编译产物打包成文件系统镜像，比如用户态根文件系统rootfs.img和可读写的userfs.img。它由多个列表组成，每个列表对应一个文件系统。字段说明如下：
-
-    ```
-    fs_dir_name： 必填，声明文件系统文件名, 如rootfs、userfs
-    fs_dirs：     选填，配置out下文件目录与文件系统文件目录的映射关系，每个文件目录对应一个列表
-    source_dir：  选填，out下目标文件目录，若缺失则将根据target_dir在文件系统下创建空目录
-    target_dir：  必填，文件系统下对应文件目录
-    ignore_files：选填，声明拷贝忽略文件
-    dir_mode：    选填，文件目录权限，默认755
-    file_mode：   选填，该文件目录下所有文件的权限，默认555
-    fs_filemode： 选填，配置需要特殊声明权限的文件，每个文件对应一个列表
-    file_dir：    必填，文件系统下具体文件路径
-    file_mode：   必填，文件权限声明
-    fs_symlink：  选填，配置文件系统软连接
-    fs_make_cmd： 必填，配置需要制作文件系统脚本，OS提供的脚本在build/lite/make_rootfs下, 支持linux，liteos内核和ext4、jffs2、vfat格式。也支持芯片解决方案厂商自定义。
-    fs_attr：     选填，根据配置项动态调整文件系统
-    ```
-
-    其中fs\_symlink、fs\_make\_cmd字段支持以下变量：
-
-    -   $\{root\_path\}
-
-        代码根目录，对应gn的$\{ohos\_root\_path\}
-
-    -   $\{out\_path\}
-
-        产品out目录，对应gn的$\{root\_out\_dir\}
-
-    -   $\{fs\_dir\}
-
-        文件系统目录，由以下变量拼接而成
-
-        -   $\{root\_path\}
-        -   $\{fs\_dir\_name\}
-
-
-    >![](public_sys-resources/icon-note.gif) **说明：** 
-    >fs.yml是可选的，对于没有文件系统的设备可不配置。
-
-6.  vendor/company/product/BUILD.gn
-
-    产品编译的入口，主要用于编译解决方案厂商源码和拷贝启动配置文件。如果某个产品被选择为要编译的产品，那么对应产品目录下的BUILD.gn会默认编译。一个典型的产品编译BUILD.gn应该如下：
-
-    ```
-    group("product") { # target名称需与product名称即三级目录名称一致
-      deps = []
-      # 拷贝init配置
-      deps += [ "init_configs" ]
-      # 其他
-      ......
-    }
-    ```
