This is the address of the instructions that cause exceptions. Does anyone here have the .S file of the output binary that has been causing exceptions? That file is absolutely necessary to get an idea of which function is actually triggering exception.
Random resets are power supply issue most of the time. But seems like something else here, I am not able to reproduce this issue.
Feel free to send me the binary files + your ESP8266 system config info on firstname.lastname@example.org so that I can check the binaries out. A .S file is much appreciated!
By the way, if you are breadboarding with ESP8266, do watch out for ground loops. A ground loop on a breadboard will mess your system if there are RF components involved.
Sent you the mail with the binaries that i've tried. Ensured no ground loops are there.
