JTAG Debugger

[arunbm123]

dear All

Please suggest a debugger for esp32.. Also send me a link from where I can buy

I purchased 3 debuggers from AliExpress FT2232 HL and Amazon and none of them are working with esp32

[arunbm123]

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 instructions on other forum: https://community.platformio.org/t/esp3 ... er/4541/20
If you follow those instructions, it should work just fine.

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 that you will have to change the debug cfg file to match the adapter you use.
By default, ESP32 is set to work with ft2232 chip (esp-wroom-32.cfg and esp32_devkitj_v1.cfg)

Hi Experts,
I am very new to ESP32 development desperately help on JTag setup. I spend my whole day in futile attempt and running on circles.
I will very much appreciate if someone who has use JTAG in Wrover kit under Windows OS can suggest some pointers

I am able to build various ESP32 samples and mostly use serial out for debug. Now I like to use JTAG and bought Wrover Kit for the sole purpose of ease of setup install so I can focus on code. I am able to load and get serialprint to work via all paths - Arduino IDE, Eclipse as well as Windows (I am using Windows 10) command line using msys32\mingw32 build environment.. if only I can get JTAG to work

I will very much appreciate your suggestions and Thank you very much

Details below-


I followed step-by-step setup guide as well as other posts (ex: https://www.ftdichip.com/Support/Docume ... s%2010.pdf) with no luck.

Steps:
1. When I connected the board via USB board both port shows up.
2. I added the 5 jumpers as suggested for JTag (see attached)
3. Run Zadig tool to reinstall the driver for interface 0 (see picture attached).
4. I installed OpenOCD tool
5. Run openccd tool as below but it keeps reporting device not found

There are no device/sensor attached to board and its running fine (I can see the serial print message from interface 1 of UART)

I am obviously missing somethings as this has been widely used with no issue. But I am not sure what is missing. I try to build openocd source under windows but run into many build issues there so stuck


My next attempt may be to switch to Linux and see I can get any better luck. I prefer Windows environment if I can make this work

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.

Thankyou CalinB,
Very much appreciate your help and information. I will try your suggestions again this weekend and update back

For now I have setup an Ubuntu system and jtag works seamlessly under bash shell with gdb debugger. I haven't try it under Eclipse but hope that will be no issue. I am considering moving to Linux now due to more friendly tool and environment even though I am not as verse with Linux yet

Very much appreciate your prompt help. You guys are awesome supporting and enabling the community of beginners and thank you for that
