I have an HiKey Early Access Board which I assume is made by CircuitCo.

I have connected it to a HDMI display and USB keyboard/mouse. When I plug in a 12v PS, and click on the power button, after a few seconds LED 1 lights and stays on, LED 0 flashes a couple times and goes out.

Nothing else happens. I don't get any signal to the display.

Am I doing something wrong? Any suggestions?
