[SOLVED] XBMC blocks GPIO usage

[hpeter]

Hi guys,

I'm using XBian 1.0 Beta 1.1 on a Raspberry Pi (Model B Rev. 2) and searched the FAQ, tried iRC and asked for help on G+ without any outcome. With a 433MHz transmitter connected to the GPIOs on the board I like to control my power sockets. This works flawless if XBMC isn't running. But somehow XBMC seems to use the GPIOs too. While it's running I cannot emit my signals like XBMC is blocking my request for some reason. Is there any implementation or applied patch which I have to disable within the media center software to control the GPIOs?

My last thought was, that there may be a timing problem since XBMC uses the CPU excessively.

Thanks in advance,
Peter
