The following error occurred during deployment to your hardware board: Could not connect to specified Arduino board. Verify that the board is connected to your host, and that the host COM port number set in the model matches the COM port number in Windows. To change the host COM port number in the model, click 'Simulation ', click 'Model Configuration Parameters'... In the dialog that opens, select the 'Hardware Implementation' pane, click 'Target hardware resources > Host-board connection' and set the COM port number. To find out the COM port number in Windows, open Device Manager and open your board in the COM ports group.

If you tried those instructions and are getting the same error, try the Set host COM port option to Automatically in the same pane area after resetting the Arduino board.
