MicroPython • Re: The latest development also raises a new question

Could it be that my Raspberry PI pico flash drive is broken?
It could be. The Pico W has a much smaller file system than Pico. When Pico W firmware first runs the Pico W file system will be created where it needs to be. When Pico firmware is installed the Pico file system will be created and the previously used Pico W file system will just become 'unused meaningless binary data' within that -

Code:

  770K                           432K           848K.------------------------------.--------------.-------------.| Pico W Firmware              | Unused       | File System |`------------------------------^--------------^-------------'.---------------.--------.----------------------------------.| Pico Firmware | Unused | File System          ::::::::::: |`---------------^--------^----------------------------------'  320K            320K     1408K
Or so I postulated until I ran into problems and discovered a Pico can get very confused with the old Pico W 'unused meaningless binary data' not quite seen as such. Or maybe it was the other way round, Pico then Pico W firmware installed.

My recommendation now, when switching between Pico and Pico W or vice versa, is always to execute 'flash_nuke.uf2' first as 'fdufnews' suggests.
