Booting Issue of EDGE V Pro Board

Hi

We have Khadas EDGE-V V13 Board. we have loaded the Edge_Pie_V191227 image on it and try to boot it but It’s just get rebooted and not able to see anything on External Screen Over HDMI except Khadas Logo.

Red LED Stays Solid for Few Seconds then White LED Blink Couple of time and then RED LED Turns off and Turn on again.

Can you guide me on what happened to the board and how we can solve it? We have not tried to boot using SD Card, If you can guide me for the steps for how to boot prepare the SD Card and boot from it I Can Try from it as well.

Board was working before but all of a sudden this happens and since then not able to boot it.

Thanks

What did you do to it?
