I just received the sabre lite board and followed the quickstart instructions to get everything set up.
When I plug in power the power LED D1 starts blinking (from the quickstart manual I was expecting it to be on all the time).
Also I do not receive any data over serial. The indicator LED for Rx on my serial adaptor blinks in the same frequency as the power indicator LED does.
I could not find anything about a blinking power LED in the documentation. Maybe someone here can point me in the right direction?
