Hi Gilles,
 = ;    Thanks for your reply. I am using 'rt_task_sleep( 100us)' at the end of every task to let Linux task run= .
With this I am able to run my application program = , but I am not able to debug using 'GDB'. Also is there any
better way to allow Linux task run instead of using 'rt_task_sleep'= ? My application has got 5 different task of
equal priority and I want to run these in Roun= d Robin fashion , I used 'rt_task_set_mode(0,XNRRB ,NULL)'
to enable Round Robin scheduling mode, but task are not getting exec= uted in Round Robin fashion.
Am I missing somet= hing ? Please help=0A me.

Thanks & Best Regards,
Sanjay

It is a b= it hard to answer without seeing any code, but there is a
simple remark = we can make: rt_task_yield does not "allow execution of
other tasks", rt= _task_yield only allows execution of tasks with same
priority as the cur= rent task. Your real-time tasks have to let Linux run
from time to time = if you want the serial port and graphic display to run
correctly, and in= order to do this they have to get suspended,
rt_task_yield will definit= ely not do that.
