Hi Gilles,

Thanks for your reply. With GDB I am able to run the application but it never hits configured breakpoints

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

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

If I do not use rt_task_sleep() my program does not work correctly. I tried to suspend each task instead of

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

'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 time 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 when you use XNRRB, because
it does not expect this bit to be set.
