I forgot to mention that the debugger says that the CPU catched a hard
fault exception.

>> Hi!

>> I've ran a debugger an its seems that its trying to do a contexts switch.
>> The GPIO test example works just fine I get this output on the serial

>>  What to do/where to go? I've just started using ARM MCUs.
>> Here is the github repo: https://github.com/blaisehorvath/RIOT I've
