Other Parts Discussed in Thread: TM4C123BH6PZ

Hi,

Currently we are using the Tiva™ TM4C123BH6PZ without OS.

And we want to dump the stack information in the NMI, or FaultISR interrupt routine, and unwind it on PC.

Is TI have some existing tool or lib to support this requirement ?

If we need to do these by ourselves, any example or recommendation ?

B&R

It looks like we don't include any code for decoding the exception stack in TivaWare. I'm attaching a C file based on some code I hacked out of a testcase that you should be able to use as an example to get started. I've not compiled this exact file but I'm pretty sure it should work. Caveat emptor!

If you've not found it already, you may find this application note on exception debugging helpful too.

Hi Dave,

After refering your example, I made some modification, and it works.

As described in the doc you mentioned, to do a full stack unwinding is hard, and may not be necessory in most of cases.

Thanks for your help.
