Getting core dump in with 2.0.15 ESP32-D0WD-V3

[eloebo]

Board

ESP32-D0WD-V3 audiokit

Device Description

Audiokit 2.2

Hardware Configuration

Default Audiokit

Version

latest master (checkout manually)

IDE Name

Arduino IDE

Operating System

Windows 11

Flash frequency

80MHz

PSRAM enabled

no

Upload speed

921600

Description

After new ESP board package 2.0.15 I got this problem. Since the default arduino behaviour is just to reboot and not show crashdump I cannot see in detail what went wrong.

Sketch

I use a precompiled library compiled with esp-idf which I include. (467kB)

Debug Message

E (331) esp_core_dump_flash: Core dump flash config is corrupted! CRC=0x7bd5c66f instead of 0x0

Other Steps to Reproduce

Suggestion: Add in the boot code to print out readable crashdump from flash from latest crash like:

I have checked existing issues, online documentation and the Troubleshooting Guide

we can not help just like that, going just by the info you gave. No code, you did not decode the backtrace with the exception decoder... all I can say so far is that you probably have corrupted heap

try erasing the flash and see if it works better

With the precompiled elf bootloaders and no solution like https://github.com/MathieuDeprez/ESP32_CoreDump_Arduino_1.0.6
the esp32 platform is not very accessable for arduino developers.

Giving up using esp32 for arduino

you do not need coredump in the logs above. You need the exception decoder to turn the backtrace into meaningful trace. And while we do not offer that specific thing, we do offer other ways to understand what is going on (JTAG, ExceptionDecorder)

I tried a J-link debugger but could not get connection to the cores either through esp-if tools (openocd and gdb running esp32.cfg with interface/jlink.cfg) or the one in arduino package (even worse, since could not connect to the debugger since some standard config with some ROOVER board)
Is ExeptionDecoder something that relies on HW or is it something in SW that could be added easily?

https://github.com/me-no-dev/EspExceptionDecoder it's software and runs in the Arduino IDE. Even if your project is not in the IDE, once you compile it, you can start the tool in the ide and point it to your project elf file. The rest will happen after you paste the backtrace

[me-no-dev]

there are other versions of it online that do not require IDE, but I can not say how well they work
