Can't Parse Core Dump with esp32_rom.elf

[priisen]

Hi All,

I have a core dump and elf file but espcoredump.py fails when using esp32_rom.elf (from https://dl.espressif.com/dl/esp32_rom.elf):

Code: Select all

paul@gfi:~/Downloads$ espcoredump.py info_corefile -c core1629 -t b64 -r esp32_rom.elf svp2.elf 
espcoredump.py v0.4-dev

    sec.sh.sh_flags) for sec in self._model.sections]
KeyError: 1044

I get this error with or without the -r option. Only deleting, renaming or moving the esp32_rom.elf file elsewhere fixes it (then there's no ROM symbols). Any way to get the ROM symbols?


Cheers

Seems like this is fixed in ESP-IDF 4.4.

Are there any other forums or sites or support channels where ESP32 issues can be resolved?
