problem with launchpad F28379D

I am trying to send pulses to gate driver my F28379D microcontroller, when I am press connected I receive this 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. ]

when I press Build I receive this error

[ > Compilation failure gmake: *** [ext_svr_c2000.obj] Error 1 C:\Users\User\Desktop\salah\TestMultilevelPulsesSSS_ert_rtw>echo The make command returned an error of 2 The make command returned an error of 2 C:\Users\User\Desktop\salah\TestPulsesSSS_ert_rtw>exit 1 Error(s) encountered while building "TestlPulsesSSS": ### Failed to generate all binary outputs.]

when I press Moniter sognal &tune parameter (external mode) is working but the problem the signal that I show in the oscilloscope not as from my simualtion, it seems it saving previos signal.

please I need to solve this issue

thanks
