Apply memory sections for model functions

Hello,

I generated a C code which is compliant with AUTOSAR from a matlab model and I would like to insert memory sections for model data and functions, so I created a package containing the memory sections and in the configuration parameters : code generation -> memory sections I selected my package and for each category : Initialize / terminate , Exceution , shared utility , constants etc. I set the defined memory section. However After generating the code, I get only memory sections for the variables, shared utility and constants but not for the model functions : Initialize and Model step functions.

Does anyone have any idea how to set memory sections for model functions ?

Hello

Could you please tell me which version MATLAB you are using? Cuz I can't find code generation -> memory sections in my settings ( I'm using MATLAB 2021a now).

Hi Nour,

You have created an AUTOSAR package with memory sections for the model initialize and step functions. A possible approach is to use SwAddrMethods in AUTOSAR and set the MemSecFuncInitTerm property using the set_param API. The default behavior will suppress the use of memory sections for Initialize, Start, and Terminate functions. The following links can be referred to for more information:

Also, since you are generating C code only, you might have to use the Code Mappings Editor - C or the Embedded Coder dictionary in order to utilize this functionality.

I hope this helps you.
