Factory reset?

[pythoncoder]

If you update the Pico firmware the filesystem contents is preserved, including main.py. Sooner or later someone is going to write a main.py which crashes the board, by poking RAM locations or by abuse of the inline assembler.

Is there a way to wipe the filesystem of an unbootable board?

I haven’t tried this yet, but there is an example program included here: https://github.com/raspberrypi/pico-examples called nuke which will erase all of flash.

It happened to me, that I made a main.py which freezed the board. But I wanted to keep the file system. So I created a firmware with a _boot.py, which erased main.py. After that, I could use the previous firmware.

This was my solution for removing main.py when it was stopping the REPL being reached, preventing rshell from accessing it, when I wanted something less than nuking everything -

Thanks, all. Good solutions.

Thanks everyone. This thread has saved me from giving up after evening one of my adventures with a Plasma 2040.
