MicroPython • Re: UART REPL Pico - Panic

I'm surprised the '.uf2' zipped up that small. Testing your firmware worked for me - and hopefully the reported version matches with yours -

Code:

MPY: soft rebootMicroPython v1.25.0-preview.301.g8987b39e0.dirty on 2025-02-19; Raspberry Pi Pico with RP2040Type "help()" for more information.>>> dir()['machine', '__name__', 'rp2']

As far as I can tell, my 'firmware.uf2' build is the same as yours - with just version and date differences, and just a few image differences. The addresses and sizes match in each -

Yours -

But there are differences in the executable image. However that seems to have come down to the order 'BUILD_FROZEN_CONTENT' finds files on disk -

Code:

<   1004B29E : IDSTR 'MP' 4A99D719 [1004255A->] "rp2"<   1004B2AA : IDSTR 'MP' 4A99D719 [1004AA2F->] "_boot_fat"<   1004B2B6 : IDSTR 'MP' 4A99D719 [1004AA39->] "_boot"--->   1004B29E : IDSTR 'MP' 4A99D719 [1004AA2F->] "_boot_fat">   1004B2AA : IDSTR 'MP' 4A99D719 [1004AA39->] "_boot">   1004B2B6 : IDSTR 'MP' 4A99D719 [1004255A->] "rp2"

If it had added files in the same order, sorted its input, I would anticipate the files being the same bar version and date.

Regardless, knowing zipping does work, here's my build, 'firmware.uf2' renamed to make things easier. I guess fingers crossed it behaves the same ...
