Change the "/" to "\" on IDF_PATH variable on your settings.
I just made a new setup on eclipse to check...
I used https://dl.espressif.com/dl/esp-idf-tools-setup-1.2.exe to install the openocd.
The setup work OK...ish...
Here is my setup:

I made an ESP32 debug template project for VsCode that work's just fine: https://github.com/botofancalin/Esp32_debug_template

https://raw.githubusercontent.com/botofancalin/Esp32_debug_template/master/img/Esp32_win_gdb_debug.jpg

You can use this template as a starting point for your project ...

That may be caused by some wrong environment variables or environment paths setup on Eclipse.

I was using Eclipse for build/debug software on ESP32 some time ago and i found it very hard and time consuming to set up a esp32 project on Eclipse.
Moving the project to a different PC is a headache too ...

The gdb response looks OK.
There must be something wrong on eclipse debug settings...
On step 6 from eclipse debug instructions, click "Browse" and select the xtensa-esp32-elf-gdb.exe on your PC

The command should be entered on command line.
The paths to gdb and openocd should be set on system environment variables.

As a alternative solution to eclipse, you can try Visual Studio Code.

Here is a quick start guide for debugging esp32 on VsCode:
https://github.com/botofancalin/Esp32_debug ...

I made a VsCode project template/tutorial that include debug settings and operation buttons:
Menuconfig, Build, Flash, Monitor, Clean.
https://github.com/botofancalin/Esp32_debug_template
The project name is named using project folder name.
So if you need your own project, just rename the folder ...

I made a template repository for esp32 debug on Windows 10 using VsCode:

https://github.com/botofancalin/Esp32_debug_template

You will find detailed setup instructions there.

The template contain the blink project.
You can extend your project from this template.

Thanks CalinB

I could not succed in debugging with FT2232HL...

Can you please tell me wiring for FT232 module ?


I will recommend FT2232HL since it have a bigger buffer so will be faster and more reliable.
Anyway, here it is the ft232 jtag connection diagram

Please note ...

Very Strange..

No one is using any debugger in this forum LOL.............


i use ft2232 debuggers with esp32:
- wrover kit with integrated ft2232hl
- custom made debugger using ft2232d
and never had any problem connecting to esp32 as long the setup was correct.

I posted the setup ...

ESP_igrr has asked like what output you are getting into OpenOCD console output while facing this issue. So that we can have idea like what can be issue into your case.

I was giving a solution to @salomonreinach problem on my post.
