I power the board without using the dock (given power from arduino uno board 3.3v) but the omega 2+ amber light turns on. Then after about 10 seconds the light starts to blink, and does not turn solid.
So I did a serial connection. When I start the device this is what I get. At the end it stay at EEPROM : read line.
