problem with TMS320F28379D LaunchPad.

Hi All, I am trying to give simple pulse output to GPIO to blink LED in F28379D Launchpad, but it does not work.

and received those error messages, first when I did connect and second error message when I did monitor & tune.

I followed the structure but did not solve it.

How to solve this issue? I am using MATLAB 2020A.

thanks in advance.

################# FIRST ERROR.

Error occurred while executing External Mode MEX-file 'ext_comm': Failed to connect to the target. A time-out occurred while waiting for the connection response from the target. Possible reasons for the time-out: a) The target is not switched on. b) The target is not connected to your host machine. c) The application for the model is not running on the target. You might have clicked the Stop button. If the Run button is not dimmed, click it. Otherwise, click the Build button, which downloads and runs your application on the target.
