no return from rtems_task_wake_after

[Samuel Bitton]

Yes I had checked that the ticks were increasing ok (did a few calls to CPU_usage_Dump) and did see the nnumber of ticks since last reset increasing all right. That's why I'm kind of stuck and wandering what else may be going wrong.

It is clock driver not timer driver.  The timer driver is only used by 
the tmtests.

It sounds like you are not getting clock ticks.  See if you are calling 
rtems_clock_tick.

If you can break and look at variables, check out 
_Watchdog_Ticks_since_boot.
If it is zero, then you aren't getting a tick.
