Console Example not working on ESP32-C6 (IDFGH-14116)

[UlissesUy]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

I compiled the example that illustrates the use of the console component (esp-idf/examples/system/console/advanced/) to create an interactive shell on an ESP chip. It compiles without problem and loads (flash) to the microcontroller without problem. But when I try to connect with idf.py monitor gets stuck. When I connect with Putty it doesn't show anything. I'm using ESP-IDF v5.3.1. and ESP-IDE development environment.
I've already searched and tried possible solutions but everything is still the same. Any ideas or suggestions? Thank you very much.
This is the message I get with idf.py:

Hi @UlissesUy
Which console output did you select in menuconfig before build? And which port are you monitoring? Also, which devkit are you using?

It looks like, you have flashed the console example for USB-UART console (which is the default for this example), you are monitoring JTAG port and using a devkit with only one port, being JTAG.

Hi Peter, thanks for your reply.
I am using FireBeetle 2 ESP32-C6 IoT Development Board. It has only one USB port. In menuconfig I used UART number 0. All settings are default.
Thanks a lot.

Looking at the dev board you are using, it seems there is no usb-uart converter, so just select JTAG console in menuconfig, and the example shall work just fine.

Either this, or, if you want to use JTAG port for debugging while running console application, you can implement a custom usb-uart console, by connecting an external UAB-UART converter to UART pins on you dev board and set the menuconfig accordingly, to which UART peripheral you have connected your external converter.
