Re: Problems building micropython-1.9.2 from source

Re: Problems building micropython-1.9.2 from source

Hi Roberthh,
Thank you again for your suggestion, it's working I built, flashed and run it smoothly. My next trial is add my own modules in further firmware build. I left Windows for awhile then my host computer is native ubuntu 18.04. How can I pre-compile my module scripts to .mpy ?
best regards,
