（2025小白全踩坑版）【OpenHarmony】移植 3.1 版本系统到 STM32F407ZG开发板
在上stm32课程，有这样一道要求：
参考了大佬的文章之后，发现出现了liteos_m.mk文件找不到的情况，于是只能另寻他路
VSCode 搭建 STM32 开发环境_vscode stm32仿真-CSDN博客
【OpenHarmony】移植 3.1 版本系统到 STM32_openharmony移植到stm32-CSDN博客
然后看到评论区也有相同的问题，估计是代码的仓库变了，但是由于根本看不懂仓库，只能另寻他路 ，经过重重困难，终于将实验做出来，在这里分享给大家
实验准备
1. STM32F407ZG 开发板 (可以是你用的具体型号，如正点原子探索者、野火指南者等)
2. ST-LINK 调试器 (板载或独立)
3. vscode
4. STM32CubeMX
5. Git 工具(默认安装)
6. OpenOCD https://gnutoolchains.com/arm-eabi/openocd/
7. arm-none-eabi-gcc 编译器下载Downloads | GNU Arm Embedded Toolchain Downloads – Arm Developer
8. make工具安装
https://sourceforge.net/projects/ezwinports/files/
下载make-4.1-2-without-guile-w32-bin.zip
9.xcom串口调试
前期安装
1. 将openocd，arm-none-eabi-gcc，make下载之后安装到环境变量
make下载完之后，直接复制到到 GIT 安装路径下的 mingw64 文件夹 Git\mingw64\，放进去选择重复文件不要覆盖
2. 找到系统变量
点击path
新建三个变量，注意该路劲需要改到自己的路径下
打开vscode 终端，输入
make --version
其他两个可以仿照这样检查是否安装成功
查看是否安装成功
git操作
创建一个文件夹，git
git clone https://gitee.com/openharmony/kernel_liteos_m.gitcd kernel_liteos_m
mkdir ./third_party
cd third_party
git clone https://gitee.com/openharmony/third_party_bounds_checking_function.git ./bounds_checking_function
git clone https://gitee.com/openharmony/third_party_cmsis.git ./cmsis
git clone https://gitee.com/openharmony/third_party_musl.git ./musl
初始化stm32cubemx
修改 HAL 库延时的基础时钟，改为其他非 SysTick 的定时器，避免 HAL 库延时的定时器和系统运行的定时器冲突：
导出
生成源码之后，在clone下来的仓库中新建一个targets文件夹，把源码放入改文件夹
文件配置
