Github UF2 file location

Assuming you want PicoMite (MMBasic), MicroPython, CircuitPython, or zeptoforth, I would read what I have written in:

Where do I download files needed for my PicoCalc?

Many users here want to use BASIC on their PicoCalcs, and assuming you are like them, you probably want to use it too. The best source for the latest PicoMite, which is a BASIC interpreter for the Pico 1(W) and Pico 2(W), adapted for the PicoCalc is here: If you want something that is interactive but more like what you would probably use on your PC, I would suggest Python in the form of MicroPython and CircuitPython, ports of which come as part of the Picoware project which you can find in th…

I would also read about the UF2 Loader here:

UF2 Loader release

The SDBoot/multi_booter bootloader that @adwuard and @guu amongst others have done a bunch of work on is fantastic but it has a couple of glaring limitations that I couldn’t tolerate: It requires recompiling every application with a custom linker script It only reads .bin files instead of the usual .uf2 format, so various platform safety features are lost UF2 Loader is a reworked version of the bootloader that fixes these two issues. Just stick (almost) any uf2 file you like onto the SD card,…

However, note that some things such as MicroPython and CircuitPython (to my knowledge), many versions of PicoMite (I know it works with some, is this true of @ernst’s latest PicoMite?) and zeptoforth do not work with the UF2 Loader because they assume full control of all flash memory on the board.

Note: On GitHub UF2 files are normally put somewhere under ‘Releases’ in most cases; e.g. for zeptoforth they are in the first file listed for each release, zeptoforth-<version>.tar.gz (where <version> is the version number of the release), within which they can be found under bin/<version>/<platform>/zeptoforth_kernel-<version>.uf2 (where <platform> should be one of rp2040_big, rp2350, or rp2350_16mib (for use with the Pimoroni Pico Plus 2(W)) (note that there is a rp2040 platform but I would not recommend it for new installations as it does not provide enough flash dictionary space for practical use with the PicoCalc).
