Flashing the device
Connect the device to your Micro-USB cable using the port labeled as DEBUG USB.
The standard method for flashing RIOT to the samd20-xpro is using OpenOCD.
Refer to https://github.com/RIOT-OS/RIOT/wiki/OpenOCD for general instructions on building OpenOCD and make sure "cmsis-dap" and "hidapi-libusb" are enabled.
On Linux you will have to add a udev rule for hidraw, like
Arch Linux
With yaourt:
Ubuntu
Although this refers to setting up the SAMR21, this guide is still very helpful to understanding how to set up a solid RIOT development environment for the SAMD20: http://watr.li/samr21-dev-setup-ubuntu.html
Supported Toolchains
For using the samd20-xpro board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
