    手头有个安信可 esp-12k 的板子,flash 能烧录上去,但是就是没法远程连接和下载。

    flash 编译命令:

    . esp-idf/export.sh && \
        cd micropython && \
        make -C mpy-cross && \
        make -C ports/esp32 submodules && \
        make -C ports/esp32 BOARD=GENERIC_S2
    

    其他命令:

    ➜  esp32 git:(master) esptool.py --chip esp32s2 -p /dev/cu.wchusbserial1420 flash_id
