🚀 How to load bootloader

Pull the boot test point low and plug in the Thing Plus RA6M5. The board will enumerate as Renesas RA USB Boot.

Then flash the bootloader with rfp-cli

rfp-cli -device ra -port COM# -p dfu.hex

Otherwise, the same hex file can be loaded through the SWD port (using a Jlink or E2 Emulator for example)

rfp-cli -device ra -tool e2 -if swd -p dfu.hex
