[SOLVED] LED1 on Debian

[morind79]

Hi All,

I use the latest Debian image from the Wiki (Release .
I see the LED1 blinking, so I wanted to remove this. I edited /etc/rc.local but I see this :

Code Select Expand


chmod 777 /dev/disp  /dev/cedar_dev /dev/ump  /dev/mali
echo 1008000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

echo 408000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

#./opt/led_blink.sh&

#startx&
#/etc/init.d/lightdm start

exit 0


As far as I know the blinking script is already commented out.
So why LED1 is still blinking, it is blinking 2 times very quicly, then wait for 1sec and so on...

Any ideas ?

Best regards
Denis

Hi!

You can change it in the FEX file, search for 'heartbeat' in it.

More info:
1) see your available LED triggers: $ zcat /proc/config.gz | grep -i trigg
2) https://www.kernel.org/doc/Documentation/leds/leds-class.txt
