blinking red led - 2 times then pause

Featured Replies

Hello, 

I currently installed Opi0 plus2 h3_Debian_stretch_next_4.14.78 but when I boot up my device, red led blinks 2times then pause and repeating again.
What does it mean? 
I have never seen this blinking red led behaviour in previous Armbian releases.

I have more than 10 differnt devices with armbian running - and this is the normal "Hearbeat" blinking code for a running Operating System.
Maybe they swapped the green for the red led ;)

 

You could check this (maybe with a different LED-name) - here from a NanoPi Neo Core2:
 

more /sys/class/leds/nanopi:red:pwr/trigger

 

none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd

You could switch that LED off with:

echo 'none' > /sys/class/leds/nanopi:red:pwr/trigger

That default LED behaviour was changed. Most likely upstream. But board works, right?

yes, it seems board works.
