Board: Arduino Due
The Arduino Due is one of the newest members of the Arduino family. It is the first ARM Cortex-M based board supported by Arduino, using the same pin layout and being mostly compatible to the existing shields (be careful for the changed pin voltage - 3V3 instead of 5V).
NOTE: In case you are wondering if flashing RIOT on your Arduino Due will overwrite the Arduino bootloader: you can be reassured. After flashing RIOT you can without any intermediate steps just go over to flashing Arduino sketches agian.

Flashing RIOT on the Arduino Due is quite straight forward, just connect your Arduino Due using the programming port to your host computer and type:
make flash
This should take care of everything!
RIOTs Makefile carries out a two step process for flashing the Arduino Due:
-
the (serial) programming port is programmed to run at 1200bps. This will trigger the on-board ATMega to reset the SAM3X and boot it to the internal serial flash bootloader
-
we use the open
bossactool to write the new code into the SAM3X's flash
NOTES:
- if
bossacfails to flash your Arduino Due and emits an error like 'Auto scan for device failed' or 'No device found on [serial port designation] ', try to press the ERASE button of your Arduino Due before trying again to flash up RIOT. - once the flashing process of your Due is done, you have to press the RESET button to actually start RIOT.
