You keep looking in the wrong direction. You are porting the I-pipe
patch to a new board, do not you think that it is your port that has a
problem rather than the tools you use to test it?
The latency task is waiting for the timer to fire, and it does not. So,
there is something wrong with the way you handle the timer. Check
__ipipe_mach_set_dec
and
__ipipe_mach_acktimer
