LED control in Odroid C4

Hello everyone!
I have a HA installed on Odroid C4 (version 7.0 from official release) and by default the blue LED flashes in heartbeat mode which is kind of annoying. According to official Odroid documentation you can control it via sysfs. Unfortunately it doesn’t work.

First of all, there is only one subdirectory for /sys/class/leds/ which is blue:status

ls /sys/class/leds/
blue:status

But even this can’t be changed:

echo none > /sys/class/leds/blue\:status/trigger 
-bash: /sys/class/leds/blue:status/trigger: Read-only file system

So, how to change the default blue LED mode? Also I can’t find /etc/rc.local file to make these changes permanent.

hi, i did it, turned off the blue LED flash
