The model that you are trying to run in External mode does not match the application running on your target. Rebuild the model, run it on your target, and start External mode simulation again.

Everytime i try to simulate my model in external mode i get this error. I dont have an idea which changes are made in my code between deploying to hardware and the start of the simulation. Is there any chance to detect these changes with some kind of workspace comparison e.g?

Could this happen because i use global variables?

Hi,

Which hardware are you using? Do you have this issue with simple models as well? If it is specific to your model, could you share the model?

[Pascal Viertel]

Im using a raspberry pi 3B V2. Simple models work perfectly but unfortunately im not allowed to publish my actual model since its a university project. I read from this error a few times via google search and i dont think it is model specific.

Hi,

Could you try cleaning up all the files related to the model on the Raspberry Pi and MATLAB as mentioned below. Save the model before deploying and relaunch the model in External Mode and then check if you are facing the same error

1. Go to the home directory in Raspberry Pi, delete all folders and files generated corresponding to the model 2. In MATLAB Current Browser, delete the slprj and all generated project and .elf files corresponding to the model.

Also, check out the below MATLAB answer.

Thank you for answering my question. Unfortunately ive done anything you told me to do in the past already, and it didnt help.
