Hello!

How can i debug "HWI Exception" error? Then it's happens, i can only see in debugger disassembly of HWI Exception handler (Break at address "0x1001bbd4" with no debug information available, or outside of program code)

I want to see call stack, that cause this error. Or other information, that can help me to find the root reason of this error.

My experience is that you typically get HWI Exception" error if the MCU tries to run code from outside the code space. This typically happen if you have a NULL pointer somewhere. I would start by checking all the pointers you use in function calls to see if they are defined.

i've already tried. My project contains 10k strings of code, threads, interrupt handlers, timers with callbacks... So it's a hard task
