Linux raspbmc 3.10.24 #2 PREEMPT Mon Dec 23 05:18:12 UTC 2013 armv6l GNU/Linux

Version 3.10 has known issues with the spi device. The GPIOs won't get switched from I/O Ports to SPI.

I downloaded following sourcecode
http://pi.cs.man.ac.uk/download/switchPinCtrl.c

compiled it

and run it

afterwards I tested the spi again

./spidev_test
workes!
