Hi,
I have an Alix-1E-Board (running voyage linux 0.9.2) and an expansion board labeled „DECT Extention 10400112-00“ (it’s a board with eight LEDs).
I can write into the LEDs control files by typing “echo 1 /sys/class/leds/alix\:1/brightness” but nothing happens. Withal I can’ find the three LEDs at the Alix-board.
So I tried to control the eight LEDs on the expansion board. After typing “echo ‘0’ > /sys/class/gpio/export” I get the error message : “write error: No such device”. (The files export and unexport are existing). Nothing else happens.
I think (I hope) the expansion board is o.k.: After voyage linux has been booted the third LED is shining permanently.
This is what I have done yet:
cd /usr/src
apt-get install build-essential
apt-get install linux-headers-$(uname -r)
module-assistant prepare
ln -s /usr/src/linux-headers-3.10.11-voyage/ /lib/modules/3.10.11-voyage/build
apt-get -y install leds-alix-source
tar -xvjf leds-alix.tar.bz2
cd /modules/leds-alix/
make
make -C /lib/modules/`uname -r`/build SUBDIRS=/usr/src/modules/leds-alix modules

depmod -ae
WARNING: -e needs -E or -F
What can I do?
Do I have to install a gpio driver? How can I do that?
Best regards
Elmo
