Esp stack tracing

Hello everyone! I got stuck at one project after trying to tracing the stack to find the error
Can someone help me with tracing this ?

Here’s the link of project’s .ini and .elf flies


ctx: cont
sp: 3ffffdd0 end: 3fffffc0 offset: 0190
3fffff60:  3ffee92c 00000001 3ffee838 40207490  
3fffff70:  3ffee92c 00000236 00000038 402052a8  
3fffff80:  3ffee92c 3ffee838 00000004 3ffeea58  
3fffff90:  3fffdad0 00000000 3ffeea18 402024d3  
3fffffa0:  3fffdad0 00000000 3ffeea18 4020553c  
3fffffb0:  feefeffe feefeffe 3ffe84f4 40100d01  


So what’s the stack trace?

You need to put (doc)

build_type = debug
monitor_filters = esp8266_exception_decoder 

in your platformio.ini, reflash, and start the serial monitor and observe the crash.

Thanks for the feedback , but i have solved the problem yet. My sketch was trying to write something in the RAM using pointers (exception 28). It was a “one character problem” but thanks a lot for the feedback
