[SOLVED] Alix LED Support for Arch

I've bought an Alix 2D13 to experiment with it.

Installation an serial console work perfect but I have problems controlling the leds.

For Debian based systems there is documentation for an kernel module named leds-alix, unfortunately it isn't inside our kernel. Compiling the module from its sources doesn't worked.

modprobe: ERROR: could not insert 'leds_alix': Unknown symbol in module, or unknown parameter (see dmesg)

[ 1831.962904] leds_alix: module license 'unspecified' taints kernel.

[ 1831.963808] leds_alix: Unknown symbol led_classdev_register (err 0)

Controlling the leds via gpio also don't work.

Anyone an Idea or perhaps an solution?. I think i'm not the only one with an alix.

hmm, you might need to rebuild the drivers

I've build (make and make install) it a few minutes previously on the same system where I have tried to load the module.

I used these sources: http://archive.ubuntu.com/ubuntu/pool/u … rig.tar.gz

Can you show your build and insmod commands?
I just tried it myself, it all works well after adding #include "linux/module.h" to the .c file.

make V=1 CC=alix-gcc KERNEL_VERSION=3.4.8 KERNEL_DIR=$ALIX/linux/src/linux-3.4.8

(scp leds-alix.ko to the target)

insmod /lib/modules/3.4.8/kernel/drivers/leds/leds-alix.ko

It's not Arch there and I have a much older board (2C3) but I don't think it makes any difference.

The include was missing, now the make command in the Makefile which is included in the archiv is working.

I can load the module and its working fine.

Thanks.
