No, unfortunately that didn't work. After flashing this is what comes up on the openocd terminal:

... and gdb then fails as before (it does stop at main but 2 Ns and into hyperspace, as before)

Thanks, understood. It would be great if you could capture OpenOCD logs at debug level (-d 3 flag at command line) including the part where gdb is trying to connect, and submit an issue in openocd-esp32 repository, attaching the logs.

Hi,

Did you check with Linux System as well? If yes then would you please provide steps or link for that as well?

If you gets success to debug core using openOCD on ESP32 board then it will be great to share steps in details for same using Windows System

Hi, no, I haven't tried it on Linux, but there shouldn't be any major differences.

The steps that I took I have documented here: http://www.irelandupclose.com/customer/esp32/jtag/

I would really recommend getting it to work on the command line first (the link gives the steps).

I'm trying to get it to work on Sloeber (Eclipse-Arduino) at the moment, but no great success yet. If I do get it to work I will post the steps.

Ok. Thanks for Quick Response.

I will check with above link and will get back to you with results. Meanwhile, I am checking same for Linux System and will let you know if any update regarding that.

Error: esp32.cpu0: IR capture error; saw 0x1f not 0x01
Means that JTAG lines of the ESP32 are either not connected to the FTDI (via a jumper block on the lower right corner of the board, see https://docs.espressif.com/projects/esp ... up-options), or there is something else connected to the same lines that is interfering with JTAG (for example, an SD card).

Additionally, you also get errors like that if your program reconfigures the JTAG gpios (12-15) to some other function.

Hi,

We have tried using command line tool into Linux and Windows System and it works fine without any issue. We are able to debug and put some break points as well as per our requirement.

So, Let me know if anyone need any help regarding same.
