ESP32-C6 builtin USB-JTAG - unable to start debug session

Postby scottv » Thu Feb 01, 2024 9:28 am

Hi

I have a custom board that is using ESP32-C6 chip and there is connected builtin USB-JTAG to USB socket to allow debugging but it doesn't work. Openocd reports error on this stage:

In the attachment I am sending an log from VSCode's Ouput->ESP-IDF view when openocd logs level was set to 3.

Tools and versions that I am using:
IDE: VSCode
ESP-IDF extension: 1.7.0
ESP-IDF: v5.2-beta1
Open On-Chip Debugger v0.12.0-esp32-20230921 (2023-09-21-13:41)

The debug session in VSCode is configured to use esp-debug-adapter. Configuration was taken from those tutorials:
https://github.com/espressif/vscode-esp ... bugging.md
https://github.com/espressif/vscode-esp ... BUGGING.md

Config files looks like this:
