Managing Leds on a Lacie 2big Nas

I am triyng to get control of the leds on a lacie 2big NAS with no luck.
My /sys/class/leds folder is always empty.
Any suggestion?

Do you know if the Kernel has gpio-leds support or there is a specific module to be loaded with modprobe?

Thanks

That's because you are using the GF Home DTB. The LED definitions are different.

There is no need to modprobe anything.

Please do what I asked:

Hi bodhi,
I was not albe to connect serial console to run the test you asked.

In any case, since that post I switched to the nas2big.dts instead of GF one.
I succeed compiling (forcing the output) a working version without the known issue of the controller of ethernet port that didn't allow to show the Lacie box on the network. Attached there is the dts and dtb I normally use.

This version allow to manual control the fan but it seems to me the kernel miss the coretemp module to check the cpu temp. I would like to create a script that control the fan rpm in conjunction with the cpu and HDD temp (drivetemp module is available with modprobe).

Currently, I cannot manage the leds event in the dts/dtb file correctly listed in the /sys/class/leds folder.

Also attached, dmesg of my system.

That will make it harder for me to help.

This kernel has kirkwood_thermal (for 6282 SoC such as this NAS and the Dell Kace M300). So check it,

cat /sys/class/hwmon/hwmon0/name
cat /sys/class/hwmon/hwmon0/temp1_input

expect output

kirkwood_thermal
<current CPU temperature>

(If hwmon is not populated, modprobe kirkwood_thermal. And I think you only need to do it once).

To do it manually in the script, you can use the /sys/class/hwmon/hwmon0/temp1_input.

To make it automatic, install fancontrol.

Boot back to sysvinit and check the /sys/class/leds again to see if they are populated.

Nevermind. I've found that the current kernel 6.9.6 does not have the LED control for this box. While other Kirwood boxes are OK with the normal LED control, this Lacie 2Big NAS actually needs an addition driver configuring in. I will look into that in the next release.

Thanks Bodhi!
That sounds great!
