I was trying to build a Simulink model into Arduino Mega 2560 but got an error as follows:-
"Error occurred while executing External Mode MEX-file 'ext_comm': ExtGetTargetPkt() call failed while checking target pkt header. Component:Simulink | Category:Block diagram error Error occurred while executing External Mode MEX-file 'ext_comm': ExtSetTargetPkt() call failed on CLOSE. Ensure target is still running"
Please tell me what is wrong with my model... I have attached my model and error message on diagnostic viewer with this question.

I ran the model in your attached file without any error messages when I disabled the overrun detection option. I got the same error message when I enabled overrun detection option at 1K Hz sampling time - Error:Error occurred while executing External Mode MEX-file 'ext_comm': ExtGetTargetPkt() call failed while checking target pkt header.
Hopefully that helps. If not, I would recommend slowing the sampling time both on the block and at the model level to 100 Hz or 1 Hz. If that also does not work, please reach out to MathWorks Technical support and they should be able to assist you with this.
