Hi, sadly no. I gave up getting only the address right before the hard fault handler. at least that gives some indication. If you search for fruity mesh on git hub and go to the beta branch, you wil☺ find my last version of that code, I think. If you manage to get it to work I am still interested ☺️

Hi Marius,

I am facing the same problem and was wondering if you were able to figure it out.

Thanks,

Wael

I managed to get a basic stacktrace by using _Unwind_Backtrace from unwind.h together with -funwind-tables. But sadly, this doesn't seem to be able to unwind the stacktrace past an Interrupt Service Routine. So, when the HardFaultHandler is called, i am not able to get the stacktrace. But this would be one of the most important places in my code where I would want a stacktrace. Any Ideas?
