I am getting this error when generating code with AUTOSAR Blockset for AUTOSAR Adaptive:

"Error:The storage class of the signal connected to 'Output Port 1' of 'autosarTestMdl/Subsystem/Event Receive' is global, thus the generated code is not reusable. Consider using storage class 'Auto', setting Code interface packaging to 'Nonreusable function', or setting Multi-instance code error diagnostic to 'None' or 'Warning'"
How to fix it?

Currently the only option to resolve this is mentioned in the error message itself. The diagnostic option cannot be set to None or Warning using the Configuration UI, which is why you need to use the Simulink API:

set_param(bdroot,'MultiInstanceErrorCode','None')
