I have not been able to flash the PicoCalc version of PicoMite onto a Pico 2 W. My pet theory right now is that Clockworkpi did not do extensive testing with Pico 2’s and kind of assumed anything that worked with a 2040 would work with a 2350. I am not even sure the version of PicoMite they used will support the Pico 2, which I don’t think was added until 6.0. Perhaps someone more familiar with the development could shed some light on this for us.
