• USB cable
• installation of Arduino IDE + SAM boards package (or GNU-ARM compiler package)

Optional : make

blink

Blinks the onboard LED (D13). Working.

NB you will need to alter paths to suit your installation in build.bat/makefile Also change the COM port for your system.

Building

cd blink
./build.bat

Win

Uploading

You may need to erase the Due manually (press erase button) to get it boot from SAM-BA bootloader. Use the native USB for programming.

D:\Git\tool-bossac-py-reset\bossac\win\bossac.exe -i -d --port=COM5 -U false -e -w -b ".\blink.bin" -R

NB There is a bug in older versions of bossac, it crashes on small bin files. You must use v1.7.0 or later which can be found at https://github.com/shumatech/BOSSA/releases
