PlatformIO Support

The PlatformIO Board file for this board is currently using the incorrect OpenOCD (Upload/Debug) script for the microcontroller on this board. We are in the process of pushing a fix upstream. When uploading or debugging, hold the reset button down right until the upload or debug process initiates it's routine in communicating with the board, this seems to aleviate the issue for right now.
