i:MX6 sabre lite power LED blinking

Hey guys,

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?

Greetz,

Chris

It could be that it is not receiving a steady 5V from its power source.

Do you have a known good 5v power adapter to try it with?, or can you measure how much power is going through the board?

otherwise it could be the PMIC
