Continuation from [Debug][Keil][STM32CubeIDE] How to debug Keil's STM32 project in STM32CubeIDE? (Part 1)

Now get back to the target Keil's project and select all following settings.
If you haven't created STM32CubeIDE's project from your Keil's project yet, then follow these two blog entries:

Now is the hardest step. You need to search for "arm-none-eabi-gdb.exe" file in your version of STM32CubeIDE - unfortunately the full path is needed.
Mine was as presented in the picture below:


I noticed several problems with loaded image by OpenOCD. I suggest not to check "Load image" option.




At this point perhaps OpenOCD is not working locally at your PC. The following error can appear then.


I suggest to use Keil to program FLASH. You can do so from STM32CubeIDE - use Build Target approach and "program_flash" command.
The picture below presents effect of FLASH programming command. It uses Keil's project settings. Of course your board needs to be powered on and connected through a debugger/programmer.


Now start OpenOCD in separate CMD window in a place where you created debug config file for a dummy STM32CubeIDE's project for the same MCU, as an example below:

Copy/paste content:

"openocd.exe" "-c" "gdb_port 3333" "-f" *.cfg"

Click to expand...

Run debug once again:


OpenOCD should detect incoming connection now:


The final effect of debugging Keil's project inside STM32CubeIDE is presented on following pictures:
