Unfortunately this devkit has an external USB-serial converter (CP2102N) connected to the USB port, not the built-in USB_SERIAL_JTAG peripheral of the C3.
You have the following options for JTAG debugging:
- connect a USB breakout cable (such as this one) to GPIO18 and GPIO19.
- move two resistors (R1 and R4 -> R2 and R3, see screenshot of the schematic below) on the PCB to route the USB lines to USB_SERIAL_JTAG
- burn the efuse to make JTAG pins available directly on GPIOs, then attach a JTAG adapter such as ESP-Prog.
I would recommend the first option as you don't need to make any permanent changes to the devkit.

I'd like to run C and assembly level debugging in Eclipse using this product https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32c3/esp32-c3-devkitm-1/index.html
I played a lot but only the code upload is working (I tried in Arduino)
I have installed the latest ESP-IDF tool
OpenOCD shows the following error:
C:\Espressif\frameworks\esp-idf-v5.3.1>openocd -f board/esp32c3-builtin.cfg Open On-Chip Debugger v0.12.0-esp32-20240318 (2024-03-18-18:26) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : only one transport option; autoselecting 'jtag' Info : esp_usb_jtag: VID set to 0x303a and PID to 0x1001 Info : esp_usb_jtag: capabilities descriptor set to 0x2000 Info : Listening on port 6666 for tcl connections Info : Listening on port 4444 for telnet connections Error: esp_usb_jtag: could not find or open device!

I tried it in both on Linux and Windows 11
Will help when we change the eFuse and using external JTAG?
Please help.
