Hi,

In my code i have added one loop which doesn't do anything in my task function. like below

void task1fxn()

{

semaphore_pend();

for(j=0;j<25000;j++);

semaphore_post();

}

If my for loop iteration value is 20000 while running code  didn't see any issue. But if loop iteration value is 25000 facing below error while running the code

To see more exception detail, use ROV or set 'ti.sysbios.family.c64p.Exception.enablePrint = true;'
xdc.runtime.Error.raise: terminating execution

can any body help me to resolve this issue? why it misbehaving if i just change the loop iteration value from 20000 to 25000.

I am using CCS version as  Version: 5.3.0.00090.
