So I am doing a lot of reading and research on this and came across this example when trying to research an answer for an exception I am getting in my project.
Do any of you know if I write something like this

uint_32 SP = 0;
#define ReadStackAddress() { asm volatile( "mov.n SP, A1); }

can call ReadStackAddress() that I could possibly do some logic to walk this stack to determine the full stack trace for NONOS SDK?

Before I go down this road I wanted to see if anyone knows this is possible without RTOS?

Here is a pretty solid example of code that touches on the stacktrace: https://gitlab.fai.utb.cz/jurenat/Espru ... d4c9da81c0

Writing this, now I see that the stack context may shift upon encountering an exception. Is that what you are talking about? Can you share how you proceeded and what have your findings been?

Beware! I know less than I give away.
