## Introduction<a name="section11660541593"></a>
The OpenHarmony LiteOS Cortex-A is a new-generation kernel developed based on the Huawei LiteOS kernel. Huawei LiteOS is a lightweight operating system \(OS\) built for the Internet of Things \(IoT\) field. With the rapid development of the IoT industry, OpenHarmony LiteOS Cortex-A brings small-sized, low-power, and high-performance experience and builds a unified and open ecosystem for developers. In addition, it provides rich kernel mechanisms, more comprehensive Portable Operating System Interface \(POSIX\), and a unified driver framework, Hardware Driver Foundation \(HDF\), which offers unified access for device developers and friendly development experience for application developers. [Figure1](#fig27311582210) shows the architecture of the OpenHarmony LiteOS Cortex-A kernel.

## Constraints<a name="section119744591305"></a>
- Programming languages: C and C++
- Applicable development boards: Hi3518E V300 and Hi3516D V300
- Hi3518E V300 uses the JFFS2 file system by default, and Hi3516D V300 uses the FAT file system by default.
## Usage<a name="section741617511812"></a>
OpenHarmony LiteOS Cortex-A supports the [Hi3518E V300](https://gitee.com/openharmony/docs/blob/master/docs-en/quick-start/introduction-to-the-hi3518-development-board.md) and [Hi3516D V300](https://gitee.com/openharmony/docs/blob/master/docs-en/quick-start/introduction-to-the-hi3516-development-board.md). You can develop and run your applications based on both development boards.
### Preparations<a name="section1579912573329"></a>
You need to set up the compilation environment on Linux.
- For Hi3518E V300, see [Setting Up the Hi3518 Development Environment](https://gitee.com/openharmony/docs/blob/master/docs-en/quick-start/setting-up-the-hi3518-development-environment.md).
- For Hi3516D V300, see [Setting Up the Hi3516 Development Environment](https://gitee.com/openharmony/docs/blob/master/docs-en/quick-start/setting-up-the-hi3516-development-environment.md).
### Source Code Acquisition<a name="section11443189655"></a>

## 简介<a name="section11660541593"></a>
OpenHarmony LiteOS-A内核是基于Huawei LiteOS内核演进发展的新一代内核，Huawei LiteOS是面向IoT领域构建的轻量级物联网操作系统。在IoT产业高速发展的潮流中，OpenHarmony LiteOS-A内核能够带给用户小体积、低功耗、高性能的体验以及统一开放的生态系统能力，新增了丰富的内核机制、更加全面的POSIX标准接口以及统一驱动框架**HDF**（OpenHarmony Driver Foundation）等，为设备厂商提供了更统一的接入方式，为OpenHarmony的应用开发者提供了更友好的开发体验。图1为OpenHarmony LiteOS-A内核架构图：

## 约束<a name="section119744591305"></a>
- 开发语言：C/C++；
- 适用于Hi3518EV300、Hi3516DV300单板；
- Hi3518EV300默认使用jffs2文件系统，Hi3516DV300默认使用FAT文件系统。
## 使用说明<a name="section741617511812"></a>
OpenHarmony LiteOS-A内核支持Hi3518EV300（[介绍](https://gitee.com/openharmony/docs/blob/master/quick-start/Hi3518%E5%BC%80%E5%8F%91%E6%9D%BF%E4%BB%8B%E7%BB%8D.md)）、Hi3516DV300（[介绍](https://gitee.com/openharmony/docs/blob/master/quick-start/Hi3516%E5%BC%80%E5%8F%91%E6%9D%BF%E4%BB%8B%E7%BB%8D.md)）单板，开发者可基于两种单板开发运行自己的应用程序。
### 准备<a name="section1579912573329"></a>
开发者需要在Linux上搭建编译环境：
- Hi3518EV300单板：参考[环境搭建](https://gitee.com/openharmony/docs/blob/master/quick-start/Hi3518%E6%90%AD%E5%BB%BA%E7%8E%AF%E5%A2%83.md)；
- Hi3516DV300单板：参考[环境搭建](https://gitee.com/openharmony/docs/blob/master/quick-start/Hi3516%E6%90%AD%E5%BB%BA%E7%8E%AF%E5%A2%83.md)。
### 获取源码<a name="section11443189655"></a>
在Linux服务器上下载并解压一套源代码，获取源码（[下载链接](https://repo.huaweicloud.com/harmonyos/os/1.0/code-1.0.tar.gz)）。更多源码获取方式，参考[源码获取](https://gitee.com/openharmony/docs/blob/master/get-code/%E6%BA%90%E7%A0%81%E8%8E%B7%E5%8F%96.md)。
### 编译构建<a name="section2081013992812"></a>
开发者开发第一个应用程序可参考：
- [helloworld for Hi3518EV300](https://gitee.com/openharmony/docs/blob/master/quick-start/%E5%BC%80%E5%8F%91Hi3518%E7%AC%AC%E4%B8%80%E4%B8%AA%E7%A4%BA%E4%BE%8B%E7%A8%8B%E5%BA%8F.md)；
- [helloworld for Hi3516DV300](https://gitee.com/openharmony/docs/blob/master/quick-start/%E5%BC%80%E5%8F%91Hi3516%E7%AC%AC%E4%B8%80%E4%B8%AA%E5%BA%94%E7%94%A8%E7%A8%8B%E5%BA%8F%E7%A4%BA%E4%BE%8B.md)。
