DCA1000EVM: DCA100EVM 5V LED blinking Red light - possible power issue?

Part Number: DCA1000EVM

I'm trying to use DCA1000 but i got a problem with the board.

the DCA1000 is powered with 5V 3A supply and all SW are set correctly.

however, the 5V_led remains blinking red and the board is not detected.

could this indicate a power issue, and should i change to another Board?
