We are revisiting testing our Alpha hardware unit. Towards the end of the winter we stopped being able to communicate with it, but gave up to prepare for the FRC season.
In its current state the green power light will come one, but nothing else happens. The mode and status lights stay off, the screen does nothing, no wifi comes up, and the Limelight Hardware Manager cannot detect it. I have tried multiple computers and usb cables. Below is a copy of of the log from the hardware manager when we power the systemcore on in boot mode:
