How do I re-install the bootloader for a SAMD21 mini dev board? I have an Atmel JTAG-ICE as I normally use the board in bare-metal mode.
If you’re using Atmel Studio or some other software that allows flashing a HEX file via your programmer, you can try flashing the attached HEX file to restore the bootloader.
