PY32 Ubuntu GCC 和Vscode开发环境搭建
今天和大家分享一下我这两天玩的py32f003，仅需6毛钱，提供HAL库和LL库，支持MDK和IAR开发
同时github上面也有gcc的模板程序，本次就介绍一下linux下基于gcc+pyocd的环境搭建
这个理论上其实是可以对接RT-Thread Nano的，这里先画一个饼，有空的时候可以试着对接一下
1. 安装 GNU Arm Embedded Toolchain
建议在实体机内下载后，传到虚拟机之中，再进行下面的解压等操作
sudo mkdir -p /opt/gcc-arm/
sudo tar xvf arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi.tar.xz -C /opt/gcc-arm/
cd /opt/gcc-arm/
sudo chown -R root:root arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/
2. 安装 PyOCD
官方建议从pip安装PyOCD，不要用自带apt仓库，不然版本太低，无法识别JLink OB
pip uninstall pyocd
/home/［user］/.local/bin/pyocd
/home/［user］/.local/bin/pyocd-gdbserver
/home/［user］/.local/lib/python3.10/site-packages/pyocd-0.34.2.dist-info/*
/home/［user］/.local/lib/python3.10/site-packages/pyocd/*
source ~/.profile
3. 克隆py32的 template
git clone
4. Edit Makefile
根据自己需要编辑Makefile
可以控制使用LL库，HAL库，FreeRTOS等
这里是针对py32f003x6型号，使用DAPLink烧录的。

5. 尝试编译，烧录
# clean source code
make clean
# build
make
# or make with verbose output
V=1 make
# flash
make flash
6. Vscode配置
c_cpp_properties.json
这个要是没有写的话会报include出错，虽然编译烧录起来都没有问题，但是代码提示功能就基本没有了。

识别不到DAPLink怎么办？
实际发现有时候运行make flash，会一直在等待debug probe connect这时候可以试试拔插DAPLINK，重连一下，以及检查是不是连接到主机了而不是实体机中。
