ESP32 exception decoding

Hi All,

Need your help in finding the issue that is causing the program to crash randomly.

I can see the stack trace in the output window as well as the exclamation button, but clicking it is not showing the source code details where the crash is happening.


Here are some details of the setup
MCU - ESP-WROOM-32 (nodemcu-32s)
Visual Studio 2022
VisualMicro version 2022.611.2204

I have attached the Exception data. Please take a look.

Thanks for the detail, please enable the settings shown at the top of the page, and perform a Build > Clean, then a build, and attach the complete build output so we can replicate your environment.

Please also supply the ELF file from the build folder for your project.

Hi Simon,

Thanks a lot for responding. Build output and .elf file are attached. Please remove .txt extension from the .elf file before using it.

Regards,
Rahul

Thanks for the detail, the exception appears to be decoded as far as it can be with the tools provided by espressif in the Arduino Board Package, as there is no stacktrace output when it crashes.

From the Load Prohibited error shown, an illegal address in memory is being accessed, and from the address shown (EXCVADDR: 0x801e2d5c) it is highly likely to be an uninitialized pointer or it has become corrupted (shown in the doc linked above).

If you disable the Debug: Serial option (set it to Debug: Off), does this make any difference to the issue?
