Runtime Stack Checking not working

Hi - I'm running C++ code on a Max10 and booting from the UFM. Everything works well enough, however, I'm trying to search for a hard to find bug. In the process of doing this, I thought I'd enable runtime stack checking. I did this by following the embedded developers guide.

 

I have enabled "runtime stack checking" and also enabled "instruction related exceptions" in the BSP. However, when I do this, the device stops booting properly - it never leaves alt_main(). It appears to continuously trigger a 'trap' exception while trying to configure the system clock timer (sys_clk_timer). However - this works fine if "runtime stack checking" is left turned off.

 

Has anyone experienced something similar?

Hi,

Can you share the BSP settings?

Sure thing. Here is "settings.bsp" renamed as "settings.xml" to allow it to be uploaded to the forum.

Thanks! Some more info that might be useful: if I remove the system clock from the BSP but leave runtime stack checking enabled, it works fine also.

I think I've found the answer. I'm using the vectored interrupt controller. Seciont 37.5.6 the Embedded Peripherals IP User Guide version 19.2 (page 452) states:

 

"The VIC does not support runtime stack checking feature (hal.enable_runtime_stack_checking) in the BSP setting."

 

That is most likely the reason then.
