hyma Posted May 2, 2022 Share Posted May 2, 2022 (edited) Hi. I use Armbian 22.05 Jammy Kernel 5.17 on my rock 3a. The blinking blue is very annoying. How can i stop this LED? Edited May 2, 2022 by hyma 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted May 2, 2022 Share Posted May 2, 2022 path to trigger file for leds is different across board families so I don't know exactly about that board. Try something like this: root@pihole:~# find /sys -type f|grep led|grep trigger /sys/devices/platform/leds/leds/orangepi:red:status/trigger /sys/devices/platform/leds/leds/orangepi:green:pwr/trigger In this case these are the led trigger files from an Orange Pi One. Use cat on the trigger file to know which values are allowed, then echo one into the file like echo heartbeat > trigger 0 Quote Link to comment Share on other sites More sharing options...

Werner Posted May 2, 2022 Share Posted May 2, 2022 Then yours probably is not named with a color but with purpose. Simply try adjusting all of them and see what happens. You cannot do any harm doing so. My best guess would be the user-led ... 1 Quote Link to comment Share on other sites More sharing options...
hyma Posted May 2, 2022 Author Share Posted May 2, 2022 thx the user-led is correct path. i used "none" to turn off LED, it's work for me echo none > /sys/devices/platform/leds/leds/user-led/trigger 0 Quote Link to comment Share on other sites More sharing options...
