Thanks, I will start there.

Where do I get the rt library? (-lrt in makefile)?

cyclictest.c: In function `timerthread':
cyclictest.c:153: error: `SIGEV_THREAD_ID' undeclared (first use in this function)

Someone got this before but no solution on how to fix it.

Aparently I don't. It's set as IS_TICK_BASED. How does this affect the system?

Thanks,
