Red LED blink on boot - watou - 06-04-2019
I had this board humming along for a good long while, and forgot about it for awhile. Now whenever I apply power, I get a quick red LED blink once a second, with no other feedback.
The board is stenciled:
A64-DB-2G-Rev B
2016-02-25
I've searched and not found any report of a red LED blinking on boot, only solid red LED.
Can anyone tell me if it's a board failure, corrupted microSD, failed PSU, anything else?
Your experience and help is very much appreciated!

To answer my own question, I found another power supply and was able to get the board going again, so without being 100% scientific about it, it looks like the power supply failed. Not being certain of the condition of the microSD card, I then replaced that as well. Hope this helps someone in the future!

Glad that you have discovered is power supply issue. I just plan to respond back the blink cause by power supply enter and release from self-protection mode.

Great information! Thank you for confirming that that PSU is definitely e-waste. Very happy to have the PINE64 running happily again.
