Embedded Coder Unable to connect to F280049C

John,

When I debug the code using CCS in F28069M it worked. When I generate the code using Matlab Simulink Embedded coder support package for TI C2000 it also works good.

When I debug the code using CCS in F280049C, it worked. But when I generate the code using Matlab Simulink using Embedded coder support package for TI C2000, it gives me the below error (only for F280049C).

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.
Embedded coder has support for F280049C still it gives error. 
Regards,
Nisha
