I bought a new PICO H 2021 and when I put any new files on it when i reboot the system they are deleted and the previously installed files come back (even after erasing them). The files I am using I know work, because I have the same set up in another display. HELP please
Welcome to the forum.
It can be tricky getting going the first time with anew microcontroller. I always start by doing the full tutorial from the manufacturer so that I know the hardware isn’t defective. Often I learn a slightly unusual procedure that needs to be followed that I’d never needed to do with other micros.
So I recommend you follow this all the way through before going back to what you were trying that failed.
