Problem in using S-function builder for changing the frequency of arduino uno in Simulink

I'm currently working on communication Arduino with simulink (R2023a) but i'm receving this error whenever i'm using this S-function builder block to change the freqncy of the Arduino

I tried to make the file path of Simulink the Matlab file but the error still

same issue, solved?

As per my understanding, you’re trying to change the frequency of Arduino using the S-function builder block but unable to do so. The error message you're encountering suggests that the code generation information file required for the S-function builder block does not exist. This file is typically generated during the code generation process and is necessary for successful compilation.

To resolve this issue, you can try the following steps:

1. Check if the code generation settings are correct. Ensure that the code generation options have been set correctly in the Simulink model. Make sure that all the required paths are specified correctly, and no conflicts exist in the interface code.

2. Make sure you have selected the appropriate options in the S-function builder block and provided the necessary information such as the Arduino board type, library paths, and custom code if required.

3. Re-check that the MATLAB file path in Simulink is set correctly. Go to the MATLAB File menu in Simulink and select Set Path. Make sure that the necessary folders containing the required libraries and files for Arduino communication are included in the MATLAB path.

4. Check if there are any missing or incorrect library or header file references in your Simulink model. If you have added any custom libraries or header files, make sure that the file paths are correct.

5. Verify that your Arduino board is properly connected and recognized by your computer. Ensure that you have installed the necessary drivers and that the Arduino board is selected as the target device in the Arduino support package settings in Simulink.

If none of the above solutions work, please provide more details about your setup, the specific steps you have followed and any additional error messages or warnings you have encountered.
