Hi

So it seems there is now something new...

Please to post

Code: Select all

ls -l /sys/devices/platform/leds-ns2l/leds
ls -l /sys/devices/platform/leds-ns2l/leds/*/*

and also

Code: Select all

ls -l /sys/class/leds
ls -l  /sys/class/leds/*
ls -l  /sys/class/leds/*/*

[fvdw]

:thumbup indeed so driver (leds-ns2l) seems to be loaded, proven by the line lrwxrwxrwx 1 root root 0 2018-01-01 12:01 driver -> ../../../bus/platform/drivers/leds-ns2l in this ouptut

I was already the case in kernel 8 but kernel 9 is little more sophisticate so lets continue with that for the moment
The probing of the driver gives no output if succesfull therefor no sign of it in dmesg

Anyhow, in folder /sys/devices/platform/leds-ns2l/leds there should be a folder (kernel #9) with name srn21c:white:sata0
In that folder several files should be present enabling us to change settings of the led

As I see Jocko already asked to post the content of that folder,
interesting will be the content of the file
/sys/devices/platform/leds-ns2l/leds/trigger
You can get content by using for example this command

Code: Select all

cat /sys/devices/platform/leds-ns2l/leds/trigger
