 ## Introduction<a name="section11660541593"></a>
 
-OpenHarmony LiteOS-M is a lightweight operating system kernel designed for the Internet of Things (IoT) field. It features small footprint, low power consumption, and high performance. It has a simple code structure, including the minimum kernel function set, kernel abstraction layer, optional components, and project directory. The LiteOS-M kernel is divided into the hardware layer and hardware-irrelevant layers. The hardware layer provides a unified hardware abstraction layer (HAL) interface for easier hardware adaptation. A range of compilation toolchains can be used with different chip architectures to meet the expansion of diversified hardware and compilation toolchains in the Artificial Intelligence of Things (AIoT) field.
-**Figure1** shows the architecture of the LiteOS-M kernel.
+The OpenHarmony LiteOS Cortex-M is the kernel designed for the lightweight operating system \(OS\) for the Internet of Things \(IoT\) field. It features small size, low power consumption, and high performance. In addition, it has a simple code structure, including the minimum kernel function set, kernel abstraction layer, optional components, and project directory, and is divided into the hardware-related and hardware-irrelevant layers. The hardware-related layers provide unified hardware abstraction layer \(HAL\) interfaces to improve hardware adaptability. The combination and classification of different compilation toolchains and chip architectures meet the requirements of the Artificial Intelligence of Things \(AIoT\) field for rich hardware and compilation toolchains.  [Figure1](#fig0865152210223)  shows the architecture of the OpenHarmony LiteOS Cortex-M kernel.

 ## Constraints<a name="section119744591305"></a>
 
-OpenHarmony LiteOS-M supports only C and C++.
+Programming languages: C and C++
 
-It applies only to Cortex-M3, Cortex-M4, Cortex-M7, and RISC-V chip architectures.
-
-As for dynamic loading module, the shared library to be loaded needs signature verification or source restriction to ensure security.
+Currently applicable architectures: Cortex-M3, Cortex-M4, Cortex-M7, and RISC-V
 
 ## Usage<a name="section3732185231214"></a>
 
-The OpenHarmony LiteOS-M kernel build system is a modular build system based on Generate Ninja (GN) and Ninja. It supports module-based configuration, tailoring, and assembling, and helps you build custom products. This document describes how to build a LiteOS-M project based on GN and Ninja. For details about the methods such as GCC+Makefile, IAR, and Keil MDK, visit the community websites.
-
-### Setting Up the Environment
-
-Before setting up the environment for a development board, you must set up the basic system environment for OpenHarmony first. The basic system environment includes the OpenHarmony build environment and development environment. For details, see [Setting Up Ubuntu Development Environment](https://gitee.com/openharmony/docs/blob/HEAD/en/device-dev/quick-start/quickstart-lite-env-setup-linux.md). You need to install Python3.7+, GN, Ninja, and hb. For the LiteOS-M kernel, you also need to install the Make build tool and [GNU Arm Embedded Toolchain](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads).
-
-### Obtaining the OpenHarmony Source Code
-
-Obtain the latest OpenHarmony source code through Git clone on a Linux server. For details about how to obtain the source code, see [Source Code Acquisition](https://gitee.com/openharmony/docs/blob/HEAD/en/device-dev/get-code/sourcecode-acquire.md). This document assumes that the clone directory is `~/openHarmony` after the complete OpenHarmony repository code is obtained.
-
-### Obtaining the Source Code of the Sample Project
-
-The following uses the development board Nucleo-F767Zi as an example to describe how to build and run the `OpenHarmony LiteOS-M` kernel project. In the local directory, run the following command to clone the sample code:
-
-```
-git clone https://gitee.com/harylee/nucleo_f767zi.git
-```
-
-The code is cloned to **~/nucleo_f767zi**. Run the following commands to copy the **device** and **vendor** directories in the code directory to the corresponding directories of the **openHarmony** project:
-
-```
-mkdir ~/openHarmony/device/st
-
-cp -r ~/nucleo_f767zi/device/st/nucleo_f767zi ~/openHarmony/device/st/nucleo_f767zi
-
-chmod +x ~/openHarmony/device/st/nucleo_f767zi/build.sh
-
-cp -r ~/nucleo_f767zi/vendor/st ~/openHarmony/vendor/st
-```
-
-For details about the directory of the sample code, see [Board-Level Directory Specifications](https://gitee.com/openharmony/docs/blob/HEAD/en/device-dev/porting/porting-chip-board-overview.md). If you need to port the development board, see [Board-Level OS Porting](https://gitee.com/openharmony/docs/blob/HEAD/en/device-dev/porting/porting-chip-board.md).
-
-### Building and Running
-
-Before the build, configure the **bin** directory of the cross compilation toolchain in the **PATH** environment variable or set **board&#95;toolchain&#95;path** in the **device/st/nucleo&#95;f767zi/liteos&#95;m/config.gni** file to the **bin** directory of the cross compilation toolchain.
-In the **OpenHarmony** root directory, run the **hb set** command to set the product path, select **nucleo_f767zi**, and run the **hb build** command to start the build. 
-
-Example:

-### Community Porting Project Links
-
-The LiteOS-M kernel porting projects for specific development boards are provided by community developers. The following provides the links to these projects. If you have porting projects for more development boards, you can provide your links to share your projects.
+LiteOS Cortex-M provides projects for three chip architectures, which are located in the  **targets**  directory. The methods of compiling and using these projects are as follows:
 
 -   Cortex-M3:
 
-    - STM32F103 https://gitee.com/rtos_lover/stm32f103_simulator_keil
-
-        This repository provides the Keil project code for building the OpenHarmony LiteOS-M kernel based on the STM32F103 chip architecture. This code supports build in Keil MDK mode.
+The  **kernel/liteos\_m/targets/cortex-m3\_stm32f103\_simulator\_keil**  directory is the Keil project directory created based on the STM32F103 chip architecture. You can download and install Keil development tools from the Internet. To compile the Cortex-M3 project, go to the  **cortex-m3\_stm32f103\_simulator\_keil/project**  directory and double-click the  **los\_demo.uvproj**  file to open the desired project. After the compilation is successful, burn the file to the corresponding board using JLINK or STM32 ST-LINK Utility.
 
 -   Cortex-M4:
 
-    - STM32F429IGTb https://gitee.com/harylee/stm32f429ig_firechallenger
-
-        This repository provides the project code for porting the OpenHarmony LiteOS-M kernel to support the STM32F429IGTb development board. The code supports build in Ninja, GCC, and IAR modes.
+The  **kernel/liteos\_m/targets/cortex-m4\_stm32f429ig\_fire-challenger\_iar**  directory is the IAR project directory created based on the STM32F429IG chip architecture. You can download and install IAR development tools from the Internet. To compile the Cortex-M4 project, go to the  **cortex-m4\_stm32f429ig\_fire-challenger\_iar/project**  directory and double-click the  **los\_demo.eww**  file to open the desired project. After the compilation is successful, burn the file to the corresponding board using JLINK or STM32 ST-LINK Utility.
 
 -   Cortex-M7:
 
-    - Nucleo-F767ZI https://gitee.com/harylee/nucleo_f767zi
+The  **kernel/liteos\_m/targets/cortex-m7\_nucleo\_f767zi\_gcc**  directory is the Makefile project directory created based on the STM32F767ZI chip architecture. The compilation commands are as follows:
 
-        This repository provides the project code for porting the OpenHarmony LiteOS-M kernel to support the Nucleo-F767ZI development board. The code supports build in Ninja, GCC, and IAR modes.
+```
+cd kernel/liteos_m/targets/cortex-m7_nucleo_f767zi_gcc
+make clean; make
+```
+
+After the compilation is successful, the executable file  **NUCLEO-F767.hex**  is generated in the  **cortex-m7\_nucleo\_f767zi\_gcc/build**  directory. Burn the file to the corresponding board using STM32 ST-LINK Utility.

 ### 搭建系统基础环境
 
-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[Ubuntu编译环境准备](https://gitee.com/openharmony/docs/blob/HEAD/zh-cn/device-dev/quick-start/quickstart-lite-env-setup-linux.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Make构建工具和[ARM GCC编译工具链](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)。
