List of UF2 files that have been tested with UF2 Loader

PicoCalc
1

Hello forum!

I’m about to receive my second PicoCalc. I’m using the first one as a “super calculator,” with several specific applications and an RPN calculator programmed in MMBASIC.

I didn’t want to use it for testing, because I’m afraid that something I’ve built might stop working. So I ordered another one, and on that one I plan to use UF2 Loader to experiment with all the available UF2 files. And that’s the reason for this thread:

Is there any list of UF2 files that have been tested and confirmed to work without issues? I’d love to see one. And if it doesn’t exist, maybe we could create it here so it becomes a useful reference for everyone.

Thanks, as always, for your patience and support.

THE BIG LIST :slight_smile:

  • picolua
  • picocalc-rogue
  • picocalc-runcpm
  • picocalc-text-server
  • micropython_pico2w
  • zx-picocalc-2w
  • picomite-pico2

as far as i understand it, the only thing that can prevent a UF2 from working with pelrun’s loader is if the firmware uses flash operations and doesn’t use the newer flashing functions which take the partitioning into account (or, in RP2040’s case since there are no partitions, ends up overwriting the bootloader)

anything that doesn’t use flash at all should probably be automatically considered to work

For the main topic, a lot of things work with the UF2 loader on my PICO2W :

  • picolua

  • picocalc-rogue

  • picocalc-runcpm

  • picocalc-text-server (framework from BlairLeduc)

  • micropython_pico2w

  • zx-picocalc-2w

  • picomite-pico2 (I am using it now to test rpncalc1)

    hope this helps

I can’t get webmite2 or picomite2 to work. Which version are you using that works with UFR loader and which version of UF2 loader?

Picomite is here : picomite all versions by pelrun, UF2 loader is v 2.3

Is there a webmite version that is uf2 bootloader compatible?

I have no idea. My guess is that there is not enough room left in the flash memory when pico2_w is enabled at compile time, but it is just a guess.

Thank you. I had not seen this version before. It is working well and nice to be able to swap OSes easily.

I had the same question. Pelrun still working out some bugs: UF2 Loader release - #181 by pelrun
