[SOLVED] JTAG DEBUGGING

[chris007]

I am trying to understand how to perform some debugging.
I use Win10, Eclipse, and ESP PROG and the following kit: https://www.esp32.com/viewtopic.php?t=12307
I am followinf this : https://docs.espressif.com/projects/esp ... debugging/ and https://docs.espressif.com/projects/esp ... ure-target assuming I should use "interface/ftdi/esp32_devkitj_v1.cfg"

Yet I get an error as follow:

C:\Users\c\.espressif\tools\openocd-esp32\v0.10.0-esp32-20190313\openocd-esp32\bin>openocd -f interface/ftdi/esp32_devkitj_v1.cfg

Error: no device found
Error: unable to open ftdi device with vid 0403, pid 6010, description '*', serial '*' at bus location '*'


I have not changed anything to the ESP PROG firmware.

EDIT: I have flashed with Zadig software and it partially solved the first error

I have now updated the ESP PROG with winUSB driver.
My new error is now
C:\Users\c\.espressif\tools\openocd-esp32\v0.10.0-esp32-20191114\openocd-esp32\bin>openocd -f interface/ftdi/esp32_devkitj_v1.cfg

Since I updated the Winusb driver with Zadig for DUAL RS232-Hs (Interface 1) and DUAL RS232-Hs (Interface 0), I don't see any allocated COM PORT to the ESP Prog in the Windows Device Manager. I only see that in the USB Peripheral "Dual RS232-HS" x 2

EDIT: Here problem while invoking openocd. Need to ask interface + board
