Intermittent CC3200 Crashing

Other Parts Discussed in Thread: CC3200-LAUNCHXL, CC3200

A bit of information about my setup

Service Pack 1.0.0.1.1

CC3200-LaunchXL v3.2

CCS v6.0.1.40

CC3200 SDK V 1.0.0

I've been having intermittent issues with the CC3200 code crashing every few minutes to few hours. Each time the code crashes, the debugger seems to wind up in either the FaultISR() function, or the prvTaskExitError() function. I have one task alongside the SimpleLink task (imagine something similar to the Out Of Box example that comes with the SDK

Reading the comments surrounding both of the functions, it says that state is preserved for inspection, What should I be looking at?

What usually causes these issues?

What are good ways to avoid/diagnose intermittent issues like this?

Thanks in advance for the help

Hi Moyerman,

Could you try to increase the task stack size just to be sure that the stack is not overflowing and causing the issue?

You could also enable the FreeRTOS feature to determine stack size used.

Best regards,

Naveen,

I have bumped up the stack size from 2048 to 3500, and it seems to run better, but it's hard to tell with a problem like this. I am using the TI-RTOS, not the FreeRTOS. Do you know of a way to view the usage with that?

Thanks

If you're using CCS you might try the RTOS Object Viewer. When paused in debug mode select <TOOLS> from the menu. You'll see <RTOS Object View> as an option. Specifically for tasks it will show allocated stack size and stack peak. Also check your linkage editor map to make sure you aren't bumping up against the boundaries assigned for storage and allow a little extra for testing if there's any question. Hope this helps. I had similar issues and usually it ends up being something simple - of course it always is once you've figured it out.

d'oh! Maybe I am using FreeRTOS. I thought the example was based off the TI RTOS, but it looks like it's pulling in FreeRTOS files during build. Where/how is this stack analyzer that you'd spoken of?

It's built into the menu of CCS. When you're in debug mode use the options listed and you should find it.
