I managed to connect the Nucleo G474RE microcontroller, but I still get an error saying that it cannot connect to GDB. I did the same on the Nucleo F303RE microcontroller, and everything worked fine, connecting without any issues.
I would be very grateful for any help.

Thank you for your post! It is possible to use the ST TSP without installing any additional external tools. If you are still experiencing the connection issue, you could check if you are using any external tools under PLECS->Preferences->Coder by clicking on the icon next to “ST”.
