Now we’re getting somewhere.
That is the STM file bug, but I am new here and just going by what I’ve read and researched. Updating the Pico 2 and the Pico to the 6.00.02 will require the STM keyboard to be upgraded.
Toml mentioned it above, and that is the selection of dip switches which you can see in my image at the end of the arrow and updating the keyboard firmware.
Check out this thread and scroll down to the bottom and you will see an image of a black window with text explaining the STM updating requirement.
On my Pico shipped with the PicoCalc, which is not a Pico 2, after flashing as described, I still have my keyboard functional.
I am in the process of following that threads advice and downloading the STM software to automatically update the keyboard following the dip switch selection.
As I said, I am new here so this is all experimenting for me, too!
