General issue report

Greetings.

I'm trying to use the debug functionality of core dump in an ESP32 development board (ESP32 DevKit v1). I enabled the core dump "save in flash" option in the menuconfig, made a simple code that just run a while loop in main without blocking the task, so a reset will trigger, and then tried to read the core dump using the following command:

espcoredump.py -p COM4 dbg_corefile

For the record, I tried the same command but with the corresponding path to the firmware ".elf" that is generated when compiling the project.

But, I get the following error in the ESP-IDF terminal:

C:\Espressif\esp-idf\v4.4.6\esp-idf\components\espcoredump\espcoredump.py:2

# ESP-IDF Core Dump Utility

Any ideas what does this mean? I used a USB to UART converter with CP210x, CH340 and PL2303 chips, because I read in a post that the problem could be realted to the USB to UART converter, but it seems that it isn't.
