Error while generating AUTOSAR code from the model

• Exported Function 'MainModel/Input' has a periodic rate but it is not associated with a timing event in its mapped runnable 'Input'. The 'Sample time' of block 'MAinModel/Input' must be set to -1.

I am getting this error when trying to generate AUTOSAR code from my model. The model sample rate is 0.002 so I can't change back to -1 here.

How to associate timing event in the mapped runnable ?

Hi,

You can follow these steps to associate a timing event in the mapped runnable and resolve the error you are encountering:

1. Open your model in the Simulink editor.
2. Go to the "Model Explorer" pane by clicking on the "View" tab and selecting "Model Explorer".
3. In the "Model Explorer" pane, navigate to the "AUTOSAR" section and expand it.
4. Locate the mapped runnable named "Input" that corresponds to the "MainModel/Input" block.
5. Right-click on the mapped runnable and select "Properties" from the context menu.
6. In the "Properties" dialog box, navigate to the "Events" section.
7. Click on the "+" button to add a new event.
8. In the "Add Event" dialog box, select the "TimingEvent" option.
9. Set the "Period" property to the desired value that matches the sample rate of your function (e.g., 0.002 seconds).
10. Click "OK" to close the dialog box and save the changes.
11. Generate the AUTOSAR code again, and the error should be resolved.

Hope it helps!

Thanks a lot! The errors were gone. But when I try to refresh it on code mapping editor to reflect all updated information, I'm getting this error:

Invalid Simulink object handle

What does that indicate?I don't get the meaning.

Hi,

It may be possible that when you made changes to your Simulink model after opening the code mapping editor, the object handle being referenced in the code mapping editor is no longer valid. Ensure that you have saved your Simulink model and try refreshing the code mapping editor again.

I see, thanks for your feedback, I tried that way as well but the same issue continue. However, I tried change in my model by changing runnables, now it's working as expected and generated the code. Thank you!
