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