Hi Dhivya,
I understand that you are getting an error regarding storage class compatibility in Code mappings. This can occur if you are using different code mappings settings for parent model and referenced model. The expected behaviour for different storage classes for signals across Model Reference Boundary is mentioned in the following link : https://www.mathworks.com/help/rtw/ug/storage-classes-for-parameters-and-signals-used-in-model-blocks.html#f1129274.
In order to change the storage class you have to use the Code Mappings Editor. Please refer to the following steps:
- Navigate to Apps tab and select the Embedded Coder app. This will open up a C Code tab.
- On the C Code tab, select Code Interface > Default Code Mappings. This will open the Code Mappings window.
- Under the Data Defaults section, you can change the storage class of External parameters to "ExportedGlobal" or "ImportedExtern".
You can view the setting in the image given below:
In order to change this setting programmatically, you may refer to the following code:
cm = coder.mapping.api.get('myModel'); % Use your model name instead of myModel
setDataDefault(cm,'ExternalParameterObjects ','StorageClass','ImportedExtern');
You may refer to the following link for more information on the Code Mappings Editor for C: https://www.mathworks.com/help/ecoder/ref/codemappingseditorc.html
