How to reference C code drivers in Simulink Project

I am trying to compile code for the TI C2000 TMS320F28377S Processor. When everything is Simulink code, everything I've got compiles fine.

However, I want to use the Sigma Delta Filter Module which there is no mathworks support for, so I am trying to reference the Control Suite Drivers for this peripheral. The question is, how do I do this and get things to link properly.

First I added the location of the driver files to my paths in the matlab workspace.

Second, I set up the Custom Code options as follows in the Model Configuration Parameters as shown below

When I compile this, I see the following output in the MATLAB console. The Report Generator gives perfect output, but when it goes to be compiled by Code Composer Studio there is a linker error.

<Linking> 

   undefined first referenced         
    symbol       in file              
   --------- ----------------         
   _SDFM     F2837xS_sdfm_drivers.obj 

error: unresolved symbols remain 
error: errors encountered during linking;

It appears that I am not linking the C files correctly. I am just trying to reference the "F2837xS_sdfm_drivers.h" and "F2837xS_sdfm_drivers.c" files from control suite into my simulink project. I then want to call the "Sdfm_configureData_filter" from the C files.

Any ideas on where I need to put these files for them to be referenced correctly or how I need to reference them in the custom code window?

Hello,

I would recommend creating an S-function with the device driver files. The following doc should be useful:
