The display board contains the K70 and Touchscreen. It is controlled by another board with another processor which manages the USB ports. We need to update our own firmware by plugging in a USB stick and having this control board send the appropriate s-records to the K70 on the display board, and reflash itself. This is a field firmware upgrade, so we can't use a J-Link or similar flashing device.
