I would like to know if there is some specific stuff to do in order to program an arduino m0 board (I know this board is not yet supported by RIOT). In fact, the Arduino M0 board does not have an embedded debugger. So I used BOSSA tool to flash my app on it. But each time, I ended by bricking the bootloader.
Arduino bootloader start at ROM address 0x00 with a 0x2000 bytes size.
Is there specific stuff to do in order to have a working app and keep a working bootloader ? (I don't want to use a hardware programmer each time i'm playing with this board...)
I looked for some documentation within RIOT but I didn't find anything on this subject.
