Esp32 , OpenOCD ,JTAG Error

[arunbm123]

hello friends

I am debugging esp32 using external JTAG and openoCD
I am using NODEMCU esp32
I am getting following error, Please give me some solution what to do ?
I am able to see JLINK in my device Manager in Windows.

$ bin/openocd.exe -s share/openocd/scripts -f interface/jlink.cfg -f board/esp-wroom-32.cfg

Error: No J-Link device found.

Windows needs to be configured to use the WinUSB (generic) driver for the J-Link, or it won't be able to see it.

We have similar instructions for the FTDI USB chip on the WROVER-KIT board:
https://docs.espressif.com/projects/esp ... ml#windows

In the case of the JLink, you need to use the same Zadig tool to change the JLink's driver to WinUSB.

(The FTDI has two interfaces, because it does both serial and JTAG, but the JLink USB device probably only has one.)

hi
As per your post I configued WinUSB

now I am getting this error..// Hope I am using correct target and interface..I am using NodeMcu esp32 development Kit

Sounds like you're missing a connection between VTref (pin 1 on the 20-pin JTAG connector of the Jlink) and the 3.3V power supply of the ESP32. Make that connection and it should start to work.

[arunbm123]

yes you are Right...loose connection

Now its giving this error

Have a look at my blog to see how to setup jtag in Sloeber (eclipse)

hello Friends

Thanks to all who supported me.

I am able to debug in ecilpse and as well as on Commad Line.

This issue was solved by connecting power line of esp32 to segger jTag.

Thanks
Arun
