OpenOCD debug issue

Hello!
Trying to debug ESP32 simple blink app, no luck so far. Console output:

I'm at tip of `master` and I'm having this _EXACT_ same issue.

Debugging has always worked for me.

I tried rolling back to `4.4.1` and `4.3.3` but no luck. I've been pulling my hair out all weekend.

Here is my exact log:

```

So partly issue resolution can be found in https://github.com/espressif/openocd-esp32/issues/223
openocd-esp32-win32-0.11.0-esp32-20211220-1339-g187c87957 version

But there is another problem now: After application uploading debug output looks like this:

Code: Select all

Info : esp32.cpu0: Debug controller was reset.
Info : esp32.cpu0: Core was reset.
Info : esp32.cpu0: Debug controller was reset.
Info : esp32.cpu0: Core was reset.
Info : esp32.cpu0: Debug controller was reset.
Info : esp32.cpu0: Core was reset.

and finally I choose the correct configuration - ESP-IDF GDB OpenOCD Debugging, with default settings - all worked out well.
