Debug problem with ESP32-C3-Mini-1U-H4

[M0nEmb]

Hello everyone!

This is my first post, because I am starting to develop with ESP. I'm trying to debug with a custom board with ESP32-C3-MINI-1U-H4 (single core). Maybe it's a very simple question but I'm not able to debug (I'm using Eclipse IDE).

I have a usb connected to the GPIO18 (USB_D-), GPIO19 (USB_D+) and GND pins. With this I am able to flash and monitor the chip. I have read that the board has a USB-JTAG built-in but I am not able to debug.

I have also tried to connect an ESP-PROG board to the GPIO4-GPIO7 pins but I can't debug either (burning DIS_USB_JTAG eFuse as explained in next doc https://docs.espressif.com/projects/esp ... ure-efuses).

I get next error when trying to run opencd with ESP-PROG connected:

Code: Select all

openocd -f board/esp32c3-ftdi.cfg

Returned:

Can anyone help me? Thanks!
