Debugging HWI error

Frank Walzer

Other Parts Discussed in Thread: SYSBIOS, CC3200

I am working on an application that has several HWI defined. In some cases I do receive the following error:

ti.sysbios.hal.Hwi: line 127: E_stackOverflow: ISR stack overflow.
xdc.runtime.Error.raise: terminating execution

There is no other info so I wonder how to find out what HWI/ISR caused this? Where can I see the stack data for HWI? I can't find that info in ROV.

Or any other tips on how to debug this? Obviously I am running an RT system that can't be stopped for test. Also my RTA/UIA options are limited as I am using AM335x.
Thanks for any help

Regards.

The Hwi stack size is determined by the Program.stack value in your .cfg file.

The Hwi stack size and usage are shown in the Task module ROV view as well as the Hwi module ROV view.

The simplest approach to resolving this error is to increase the size of the Program.stack value in your .cfg file until the problem goes away.

Once you've been able to eliminate the stack overflow, you can then use one of the ROV views to determine how much Hwi stack is actually required for your application.

I am having this same problem with a CC3200 right now. Where is the project's .cfg file located at?

Hi Jon,

The *.cfg file is the BIOS configuration file and is typically located within your project. Are you using TI-RTOS or SYS/BIOS?
