During build MicroPython for the ESP32, I ran into an below error.
I refer to this
https://github.com/micropython/micropyt ... orts/esp32
At the stage of building 'esp-idf', No problem and get through the 'hello_world'.
But, at the time of 'make' to build Micropython for esp32, the error happened.
Thanks if share your experience or give me the advice to solve this problem.
