Hello! I have 20 Udoo Bolt V3's that I am using in some arcade cabinets. The manufacturer building the arcades has them now. Several of the units are not working. The only LED is a blinking one on the power supply. I'm using the one from the Udoo store. Does anyone know what a blinking LED on the power supply means? As they describe it, there are no LEDs active on the Udoo itself. But I will need to confirm that.
