SAME51 update for Adafruit Feather M4 CAN? #183

Closed JayToltTech closed 2 years ago

JayToltTech commented 2 years ago

I'm looking for source for the the SAME51 update to this which was done to support the Adafruit Feather M4 CAN device which comes with a UF2 bootloader. Unable to find it here or in TinyUF2 or...?

My goal is to add a UF2 bootloader process to the SAME54 XPlained board so I can prototype with ThreadX there with the goal of eventually bringing this over to the SAMD/SAME Feather boards, so I figured I would see about getting a compatible bootloading process going there.

I am not sure it needs a different build than the regular Feather M4 bootloader. From the bootloader's point of view, the chips are essentially the same.

Thanks for the pointer. make BOARD=feather_m4_can built a bootloader I was able to flash onto the board using edbg, it builds using the samd51 flags.
