mkdir -p ~/esp
cd ~/esp
git clone -b release/v4.3 --recursive https://gitee.com/EspressifSystems/esp-idf.git

Step4: 下载工具及更新

cd ~/esp
git clone https://gitee.com/EspressifSystems/esp-gitee-tools.git
cd esp-gitee-tools
./submodule-update.sh ~/esp/esp-idf

Step5: 安装

cd ~/esp/esp-idf
export IDF_GITHUB_ASSETS="dl.espressif.com/github_assets"
./install.sh

Step6: 设置环境变量

. $HOME/esp/esp-idf/export.sh

#问题

#安装依赖库报错

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)

E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

sudo rm /var/lib/dpkg/lock-frontend       
sudo rm /var/lib/dpkg/lock

#编译命令

~/esp/esp-idf$ . ./export.sh

进入工程目录，如hello_world

idf.py set-target esp32s2

idf.py menuconfig

idf.py build

下载：

idf.py -p /dev/ttyUSB1 flash

监测打印

idf.py -p /dev/ttyUSB1 monitor
