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.

[NADIA EL GUELOUI]

Hello, can you tell me which path you are talking about? Are you talking about the path of the simulink model? can you explain me the solution please because I have the same problem.

Thank you

你好，我也想请问一下，这个路径是什么路径，我该如何缩短？很希望你能回复我

I'm using stm32 code gen adb changing the location (path) of the ioc file solved this for me.

[Akshay Gugnani]

Can you please tell me how to do that ?

[Mike MacNeil]

Had same issue. I had to copy the folder with my model to location with shorter path.

Incredible that this is an issue,

The limitation imposed by Windows 10 has been 260 characters including drive letter and colon.

Windows has an Insider Preview that raises the limit, that you could potentially test out; see https://mspoweruser.com/ntfs-260-character-windows-10/

This is not a MATLAB limit, this is a Windows limit.

先不要点Simulink,就是在打开matlab内个界面，然后你看新建和打开的下面有一串文件地址，小文件夹图标从左往右点第三个，然后你就可以选择路径了，你直接选择你把simulink之后内个文件的路径直接选进去就可以了，亲测有效。

Can you please try building corresponding example model once?

To launch the example model, please execute below commnd in MATLAB command window:

>> androidGettingStartedExample

[Shaw]

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