Can't get Launchxl-F280049C to download simulink code

Hi

Just made a very simple model to flash led on launchxl-f280049C appears to compile but will not download

Checked com port that device manager shows,

XDS110 Class Application/User UART (COM8)

XDS110 Class Auxiliary Data Port (COM5)

Pushed reset button Led 4/5 flash green and red Ti logo comes up then ADCINA5 is displaying atod sampling.

Q. What do I need to check to get matlab to download models to this board?

U:\ECE\UofC Projects\R_D441\2020\Matlab\F280049\R2019b\flash_led_ert_rtw>exit 0
