ARMv7 Cubietruck LiPo-Battery

[Regenschein]

Good evening everyone,

I used cubian to some point, but as I am using arch on my usual computers, i like to have it on my cubietruck.
I just cant find any information on using a external akkumulator to power the CT without interruption.

Is there anyone who got this setup running safely. On cubian it was relatively easy to tell the board what to do with the battery.

This is what I find.
$this->bbcode_second_pass_code('', ''/sys/class/power_supply/battery': No such file or directory
')

Also all information regarding a battery relates to script.bin, but afaik ArchARM uses device tree. I hope someone can set me on the right path. I might have overlooked some stuff.

Thank you
