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

I tried to put JLINK Open SDA and it doesn t work either.

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.

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,
