I have trying different example codes in simuling for android.

" Code generation information file does not exist. "
What does the error mean?

The issue was with path. The path was too long for the model to execute. I have shortened the path ,now the model works fine.

By default, I work in the Downloads folder, but anything with a short name, preferebly without space in the path would do, to be on the safe side.
Additional problems can be backup services, like OneDrive, which can sause the same issue - hence I use Downloads folder, as that is not backed up.

I solved this problem by setting the workspace path to the same path as my Simulink file.

It's a mystery to me why Simulink doesn't automatically set the correct path and you have to manually do it in 2023.

For me it was the space character somewhere in the path.

I have tried for the above mentioned example.
The model executed with warnings.
But when I try to do with other examples, again the same error occurs.

I also faced the same problem. However, the fix for me was that I was using the wrong programming cable (some usb cables are just for power not for programming)

I had this problem from long time. There is problem with matlab version 2022b and 2023 onwards. They dont set automatically the path which sometimes cuase this error. I opted to 2021 matlab, there you will have communication interface option to select SERIAL. I simply select this and now working. TI Launchpads the solution with problems :)

Hey, I'm facing the exact same issue with the F28335 control card. I wish to generate PWM pulses to a DC DC converter.
You mentioned that the issue is with the path not being set automatically. May I know the path to which file you are talking about here? If you can mention that, maybe I can try adding that and check if it works.

The path itself doesnt resolve it. You need to make sure your simulink file and workspace path is same. It can be accessed from the top ribbon of main window of matlab (command prompt area)

In Model settings,choose Gnerate code only.

Go to the examples given in add ons - c2000 block set. There you will get the accurate solution.

Had the same issue on windows 2022b. For me, it was a permissions issue. Running MATLAB as an administrator fixed it.
