HWi Stack Overflow w/ HWi stack at 3192?!?!?!?

Edward Averill

I'm having a really strange issue with SYS/BIOS and the Hwi/Swi stack.

In the app.cfg, SYS/BIOS Basic Runtime Options, Runtime Memory Options, I have the System stack size set to a ludicrous 3192.. and yet, I'm getting "Hwi stack overflow" errors randomly in my application! When the app crashes, I use the ROV to check each tasks stack and they're all well under their allocated sizes, so I'm pretty sure none of my tasks are misbehaving...

Does anyone have any idea what might cause this? I'm out of ideas...

Hi Ed,

The system stack and Task stack are 2 separate entities. If you're getting a "Hwi stack overflow" error, then it most likely has nothing to do with your Tasks. Can I see your cfg file where you set your system stack size and create your Hwis. Also can I see the your Hwi functions?

Thanks,

Moses

Good morning! I just chased the issue down.. one code path was calling a function that had too many automatics for an interrupt context, so I fixed tht and boom, problem gone.
