Hi,

I'm trying to do a task slicing uning a clock module.

But when i execute the code i get this error :

Taskti.sysbios.knl.Task: line 365: E_spOutOfBounds: Task 0xc008920 stack error, SP = 0xc0059d0

I verified the task stack and it's above stackPeak as shown in the scrrenshot

The .c and .cfg are attached below :

Hi Youssef,

I'm suspecting you're trying to do some "time-slicing" scheduling. I presume you've already taken a look at the SYS/BIOS Users guide. It has a "Time-Slice Scheduling" section which looks very similar to the code you've attached.

You're getting a task stack overflow in your "eqTaskFxn" and it should be increased. (Notice that your high-priority task is also close to its peak).

Thanks TOM,

I increased the stack size and it works perfectly now.

Can anyone tell me how to increase the stack size for Hwi in CCS.

Hi Satyaprakash,

You can change the System stack size using XGCONF's Runtime view. System stack is used as the stack for Hwi and Swi.

Best,

Ashish
