I am trying to build a model on simulink for Arduino Uno. When i run the simulation it runs fine, but when i try to build the model it gives me an error.

Have you contacted Technical Support with the MathWorks? It could be a bug and they can let you know if there are any known fixes.

Hi Akshay,

Just want to make sure you are following the right procedure of downloading the generated code onto the board. Can you follow the steps in this video and try ?

Cheers, Abhishek

Answer 2

[Samuel Ignatius]

Hello I have the same problem on Windows 8.1, MATLAB R2015b. However, I don't have a problem connecting Arduino to MATLAB, but this problem occurs even if I run the example code.

Answer 3

[Walter Roberson]

In the case posted above:

The file C:\Users\Saaranga\Documents\MATLAB\untitled_grt_rtw\untitled.obj already exists and its permissions do not permit it to be written to. Delete the file and try again.
