Unable to Run Arduino Nano on External Mode

https://www.mathworks.com/matlabcentral/answers/502313-simulink-unable-to-upload-to-arduino-nano-3-0-linux

From Here onward it works for the simulink, but I am unable to run in external mode and try to "Monitor and Tune"

Deploying the code onto the arduino works. And even on an Arduino Uno it works. But I run into this issue on Nano

This is the error I am getting. I've tried the method used here but it doesn't work.

Hi Jason,

Please contact MathWorks Technical Support.

I am having the same problem with my arduino uno (clone). I have tried to change the baudrate that has been told but it did not work , im still getting the same error as you do. Have you found any solution ?

I have faced a similar issue (though I do not rememeber the error message): the code was ok to be build and deployed but could not run with the tune&monitor mode. I found out it was a memory issue: Tune & Monitor add too much code to be supported by the Atmega368p. I upgraded to an arduino Due and it worked fine.
