Coolwatcher program does not open gdb launcher

I want to use the gdb launcher found in the Coolwatcher program. When I click the gdb launcher from the Tool tab, I get a “failed to detect chip” error.

could you please tell us the module type and firmware version?

Any resolution on this? I am facing the same issue with EC200UCN, SDK version EC200UCNAAR03A02M08_OCPU
