I don't know whether the board is bad or not. It is definitely not a systematic problem with the IOIO-OTG. This feature is being tested and used on every individual board and no one has ever reported this problem in the past. If pin 1 is being pulled low by the motor controller, then every time you boot it *into bootloader mode* (that is, not every time you boot it in general), it will wipe the configuration memory, resulting in the fast blink you're seeing. If you ever see the wipe happening without you booting into bootloader mode, something is definitely broken with either the board or the setup it is on. Lastly, after a wipe, it should never take more than one attempt to get it calibrated. So again, something irregular here.
