+**Problem 5:** **What should I do when no command output is displayed?**
+
+-   **Symptom**
+
+    The serial port shows that the connection has been established. After the board is restarted, nothing is displayed when you press  **Enter**.
+
+-   **Possible Causes**
+    -   The serial port is connected incorrectly.
+    -   The U-boot of the board is damaged.
+
+-   **Solutions**
+
+    **Solution 1: Change the serial port number.**
+
+    Start  **Device Manager**  to check whether the serial port connected to the board is the same as that connected to the terminal device. If not, perform the following steps to change the serial port number.
+
+    **Figure  10**  Procedure for changing the serial port number<a name="fig16441825145717"></a>

+
+1.  Disconnect from the current serial port.
+2.  Click  **Settings**.
+3.  Change the serial port number in the dialog box and click  **OK**.
+4.  Press  **Enter**  in the dialog box to check whether any command output is displayed after the connection is established.
+
+**Solution 2: Burn the U-boot.**
+
+If the fault persists after you perform the preceding operations, the U-boot of the board may be damaged. You can burn the U-boot by performing the following steps:
+
+1.  Obtain the U-boot file.
+
+    >![](public_sys-resources/icon-notice.gif) **NOTICE:**

+
+2.  Use HiTool to burn the U-boot.

+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“Serial port”按钮，弹出串口终端的配置界面。

+>-   DevEco串口连接功能待上线，敬请期待。
+>-   该样例中使用IPOP（或其他）串口工具进行演示，IPOP工具请开发者通过互联网获取。

+1.  通过USB线，连接Windows工作台和Hi3861开发板，确认待连接串口为COM11，如下图所示。

-2.  选择串口，并完成参数配置。根据实际情况输入串口号，此处为“COM11”；波特率、数据位、停止位使用默认值；由于AT命令输入需要以“\\r\\n”结尾，否则输入无效，所以结束符处输入“1”。

+
+2.  在Windows工作台上，使用IPOP工具，连接WLAN模组串口（COM11），并配置好波特率115200，同时勾选Newline，确保输入字符串以"\\r\\n"结尾，避免AT命令无法输入。

+该仓库用于存放DFX框架的代码。主要包含DFR（Design for Reliability，可靠性）和DFT（Design for Testability，可测试性）特性。

 由于芯片平台资源有限，且硬件平台多样，因此需要针对不同硬件架构和资源提供组件化且可定制的DFX框架。根据RISC-V、Cortex-M、Cortex-A不同硬件平台，提供两种不同的轻量级DFX框架，以下简称mini、featured。

 -   mini框架：针对处理架构为Cortex-M或同等处理能力的硬件平台，系统内存一般低于512KB，无文件系统或者仅提供一个可有限使用的轻量级文件系统，遵循CMSIS接口规范。

-   featured框架：处理架构为Cortex-A或同等处理能力的硬件平台，内存资源大于512KB，文件系统完善，可存储大量数据，遵循POSIX接口规范。

-在分布式场景下，不同终端设备的硬件能力和运行系统环境都不尽相同，这些设备在分布式场景下，均需要建立信任关系，最典型的应用即是HiChain可信互联。那么就需要这样一个统一的密钥管理服务，来做到接口一致，密钥数据格式一致，同时提供业界标准的加解密算法实现。HUKS基于此来提供统一的密钥管理、加解密等能力。

 HUKS模块整体分为北向接口，南向适配层，以及核心的功能模块：

-1.  HUKS 北向接口：提供统一的对外API，用C语言实现，保持所有设备一致；主要包括密钥生成API、加解密API等；
-2.  HUKS Core Module：依赖HAL层，提供核心功能：加解密、签名验签、密钥存储等；
-3.  HUKS HAL层：屏蔽底层硬件和OS的差异，定义HUKS需要的统一底层API。主要包括平台算法库、IO和LOG等；
