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 samd10-xmini is using edbg.
by calling: make BOARD=samd10-xmini -C tests/leds flash
Note that on Linux, you will need libudev-dev package to be installed.
Users can also use openOCD to flash and/or debug the board using:
PROGRAMMER=openocd make BOARD=samd10-xmini -C tests/leds flash
On Linux you will have to add a udev rule for hidraw, like
echo 'KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"' \
| sudo tee -a /etc/udev/rules.d/99-usb.rules
sudo service udev restart
Known Issues / Problems
I2C
The I2C pins on the board do not have any pull-ups connected to them.
That means that running e.g. i2c_scan without any I2C slaves connected
will run into timeouts.
