Unable to write to Simulink cache file 'C:\modelname.slxc' because you do not have write permission for the file.

when I am trying to generate c code from my model, I encounter this error, how to resolve this?

Is your current directory C:\ ?

[Tejas]

yes, the directory is C, all my models are saved in C.

I mean C:\ itself not somewhere inside of the C drive.

You would get this error if your current directory is C:\ itself. Your current directory needs to a directory that you have write access to.

Thanks, this issue is resolved by setting the right path, was not on the right path before.

but after doing this encounter other problem, when try to generate c code

The function call input associated with inport 'modelname' has been configured use the name 'trial ' as the method name during code generation, which is not a valid identifier. Change the name of the signal associated with this inport or the name of the inport so that it is a valid identifier name.

which name I need to change, the function name? still not clearly understand this.

[Walter Roberson]

Edit the signal name so that it is no longer "trial " and is instead "trial" (no trailing space)

[Tejas]

I see, I changed it and now it's working; finally I am able to generate the code.

Thanks a lot for your quick feedbacks.

How did you changed the directory?

[Tejas]

Just go to your MATLAB home page, and change the folder where your model is saved..

like this example: there is a folder icon with green arrow --> just change that to the folder where your simulink model is saved... that will change to right directory..
