I follow this video : https://www.youtube.com/watch?v=qa2406iiSbI&t=177s But at min 32:52 from the video I get an error with could not openport /dev/ttyUSB0 permission denied. There are more warnings about file /home/vagrant/esp-idf but I can not paste that in here because I have no support to copy ...

Thanks for the reply
Now it is compiling.

Thanks

Thanks. But into the mpy-cross dir with make I get the same error

I also tried that but then I get the same warning.
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity

Thanks

I have a problem with building the firmware with make -C mpy-cross.
I get an error with: Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity
I follow this tutorial: https://github.com/micropython/micropyt ... sp32/esp32

What I am doing wrong.
