Firmware Updates

You can load the latest precompiled binary file from the firmware directory, without installing the Arduino IDE. You can use the bossa mattairtech port (https://github.com/mattairtech/BOSSA) with the following command (substitute comX with /dev/ttyUSBx under Linux/OSX):

bossac.exe -i -d --port=COM19 -e -w BRTRO-1.04.bin

The precompiled Windows binary is in the firmware directory (bossac-1.7.0-mattairtech-3-mingw32). The src files can be compiled easily under Linux/OSX using the make command. The official bossa release doesn't yet support the SAMC21 so this modified version by mattairtech must be used.

Please note, when reprogramming firmware, all flash variable storage will be erased. So be sure to take note of your settings before reprogramming.
