I have tested this working properly on a Pi Pico 1 now. I am not too confident in my understanding of the RIOT packages makefile system so I am happy to hear feedback 😄 |
|
Wouldn't it be easier to use the precompiled binaries of picotool instead of compiling it on demand: https://github.com/raspberrypi/pico-sdk-tools/releases ? |
|
Given the way elf2uf2 worked and looking into other packages + the documentation I would have assumed that the preference is to avoid binaries when possible |

Contribution description
The Pi Pico 2 requires a more modern version of elf2uf2 called picotool, in a first effort to get the Raspberry Pi Pico 2 to be compatible with Riot I thus needed to update it.
While this PR is intended to allow me to work on the Pi Pico 2, picotool also offers advantages for the Pico 1 such as easier device detection, loading/flashing and the ability to easily verify the integrity of a file after loading it onto the device. I have incorporated these advantages into the existing workflow so hopefully the flashing process should have become easier for everyone 😄
Testing procedure
I verified it working with examples using the pi pico 1, the expected outcome is that the user should not experience any differences while flashing (aside from the tool being different)
