NEW GUIDE: How to Program SAMD Bootloaders #SAMD21 #SAMD51 @microchipmakes

Do you have a bricked Adafruit SAMD board that won’t boot into CircuitPython, or show up as a boot volume?

Are you building your own SAMD board and want to flash our UF2-SAMD bootloader onto it?

This new guide covers wiring a J-Link to a SAMD board, flashing the bootloader, and (optionally) installing the latest CircuitPython build.

This process does require extra hardware and some software installation time. It is unfortunate when a microcontroller’s firmware is corrupted – it does not happen often. But, rather than buy a new board and have one sitting, this process will get your original board back to 100%.
