Hello, my name is Pavel, and I will be supporting your case, the image you attach looks like the debug probe works fine but this does not find the MCU maybe this is in an unknown state, I recommend doing an erase of a flash.

You could try these options depending on the firmware of your debug probe and try the "erase flash action" option.

Best regards,
Pavel

Hello, thanks for being clear, I understand now, so It's seeming like the debug cannot access to the MCU, could you try with the NMI SW1 down?

Then use the GUI.

Best regards,

Pavel

I found the fix!!!! I configured PTC4 as a GPIO, but the default config is OPEN SDA Clock Pin.
