I will see what I can do.

The time is getting very quickly when I replace
"status = rtems_task_wake_after(task_index * 5 *
rtems_clock_get_ticks_per_second());"
with
"status = rtems_task_wake_after(task_index * 5);"
Though it goes very quickly. That was how I make sure ticker is
working and do not wait too much as for the case now.
When I used FAST_IDLE mode, I did not get output from ticker.exe. I
have configured or1ksim to run at 100MHz (10 ns) from sim.cfg and
added a definition for that at or1ksim.h which is used from uart.h
driver.

Yes, I am trying to debug with Sebastian's solution you provided.
Hopefully I'd find the bug soon.

Thanks,
