Hi Gilles,=

Thanks for your reply. Wit= h GDB I am able to run the application but it never hits configured breakpo= ints

and it takes little longer time to start applic= ation. I tried changing priority of tasks, but it didn't help.

=

In my application program I have not configured any interrupts a= nd completely dependent on Linux drivers.

If I do no= t use rt_task_sleep() my program does not work correctly. I tried to suspen= d each task instead of

using rt_task_sleep and = resume them in shadow task but some how it did not work .

<= div>'rt_task_set_mode(0,XNRRB ,NULL)' didn't return any error = , but when I tried with T_RRB parameter

instead of XNRRB it failed.

Best Regards,

Sanjay

What happens when you try and= debug with gdb?

First, the application should wait interrupts and = react upon them, not
do any polling, this should normally leave some tim= e for Linux to run if
the system is well dimensioned.

I do not think round-robin is what you want: = it will not let linux run.
rt_task_set_mode probably returns an error wh= en you use XNRRB, because
it does not expect this bit to be set.
