步驟如下:

$ sudo apt-get update
$ sudo apt-get install gcc git wget make libncurses-dev flex bison gperf python python-pip python-setuptools python-serial python-cryptography python-future python-pyparsing python-pyelftools

$ cd
$ wget https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz
$ tar xvf xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz
$ sudo mv xtensa-esp32-elf /opt/esp32

$ cd
$ git clone --recursive https://github.com/espressif/esp-idf.git
$ export IDF_PATH=~/esp-idf
$ cd esp-idf
$ python -m pip install --user -r requirements.txt
$ cd examples/get-started/hello_world
$ export PATH=$PATH:/opt/esp32/bin
$ make menuconfig

依據偵測到的ttyUSB


編譯

$ make

插入USB後,執行如下命令燒錄

$ make flash

This is ESP32 chip with 2 CPU cores, WiFi/BT/BLE, silicon revision 1, 4MB external flash

假如無法燒錄,則可以使用esptool.py進行燒錄

$ cd $IDF_PATH/components/esptool_py/esptool
$ ./esptool.py --baud 920600 write_flash --flash_mode dio --flash_size 4MB 0 hello-world.bin
