$ cd ~

$ git clone https://github.com/micropython/micropython.git

# v4.3 并不是一个分支，所以后期无需更新
# 不选择主分支是因为第一次使用主分支进行编译的时候出错了

$ git clone -b v4.3 https://github.com/espressif/esp-idf.git

$ cd micropython
$ git submodule update --init --recursive

$ cd ../esp-idf
$ git submodule update --init --recursive

# 反正也不会一次就能完成，干脆重复执行它 100 次~

$ for i in {1..100}; do git submodule update --init --recursive; done

# 工具只需要安装一次即可

alias get_idf='. $HOME/esp32_idf4/esp-idf/export.sh' # 保存并退出

$ source ~/.profile # 刷新配置文件

$ cd ~/esp32_idf4/micropython
