ESP backtrace decoding from remote serial data

[robpat]

Hello all,
We have a system with 2x EST8266 modules, the slave modules appears to crash after 7 or so hours of running, the error gives me a backtrace code and the system constantly reboots until it is manually power cycled.
I am logging the serial data onto an sdcard at a remote location, so cannot use the ESP decoder in Visual Studio code.
Is there a way to decode the backtrace code from a txt file?

Here is the serial data info:
Backtrace: 0x40083e61:0x3ffbf54c |<-CORRUPTED

ELF file SHA256: dd99327f2e20cd10

Any help with be greatly appreciated!

Here are instructions for an esp32, but the 8266 has a similar xtensa-lx106-elf-addr2line binary. It will be in ~/.arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/<version>/bin, or a similar structure in .platformio. You will need the exact elf file that was compiled into the firmware.

Thank you for the help

I installed the tasks.json and can run backtrace in VScode.

"

It looks like I do not have "xtensa-esp32-elf-addr2line", should this be part of an ESP library I have installed already?

Aha, I managed to run this in powershell.


0x3ffbf54c: port_IntStack at ??:?

and

0x40083e61: panic_abort at /home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/esp_system/panic.c:408

Now I just need to work out how to understand the output
