<div>Hi,</div>
<div> </div>
<div>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).</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>I think (I hope) the expansion board is o.k.: After voyage linux has been booted the third LED is shining permanently.</div>
<div> </div>
<div> </div>
<div>This is what I have done yet:</div>
<div> </div>
<div>cd /usr/src</div>
<div>apt-get install build-essential</div>
<div>apt-get install linux-headers-$(uname -r)</div>
<div>module-assistant prepare</div>
<div>ln -s /usr/src/linux-headers-3.10.11-voyage/ /lib/modules/3.10.11-voyage/build</div>
<div>apt-get -y install leds-alix-source</div>
<div>tar -xvjf leds-alix.tar.bz2</div>
<div>cd /modules/leds-alix/</div>
<div> </div>
<div>make</div>
<div> make -C /lib/modules/`uname -r`/build SUBDIRS=/usr/src/modules/leds-alix modules</div>

<div> depmod -ae</div>
<div> WARNING: -e needs -E or -F</div>
<div> </div>
<div> </div>
<div>What can I do?</div>
<div>Do I have to install a gpio driver? How can I do that?</div>
<div> </div>
