Support for the spark-core board.
Spark's hardware dev kit, the Spark Core, provides everything you need to build a connected product. We combine a powerful ARM Cortex M3 micro-controller with a Wi-Fi module to get you started quickly. The design is open source, so when you're ready to integrate the Core into your product, you can.

|up to 72MHz (using the on-board 8MHz Oszillator of the ST- Link)
|10 (9x 16-bit, 1x 32-bit [TIM2])
|2.0V - 3.6V
First of all make sure the your spark core device is detected and can be accessed properly. In Linux you might have to adept your udev rules accordingly:
now replug the usb cable and flash.
To flash RIOT to the spark core you need to install
dfu-util (tested with 0.7 and 0.8).
Power the device and press the the
mode button until the LED flashes yellow/orange: now the device is ready to get flashed.
To run RIOT it is required that you run the newest spark bootloader on your core: from https://community.spark.io/t/replace-core-firmware-with-riot-os/7007/7
