Why do I receive a "WARNING: invalid compiler option --float_support=fpu32" message when trying to build my code with Target Support Package TC2 3.0 (R2008a)?

I am using Target Support Package TC2 3.0 (R2008a) to build and deploy code to a c2833x processor. Here is the output I see during the build process:

I notice that even though my code compiles fine, I still receive the warning message.

In addition to TI Code Composer Studio 3.3, there are four add-on packages that need to be installed in order for full Target Support Package TC2 support. They are

- Service Release 8 (3.3.77) for Code Composer Studio

- TI C2000 Code Generation Tools v5.0.0

- Spectrum Digital Driver Release 3.03.23

- TI DSP/BIOS 5.32 (for RTDX support)

All four packages can be downloaded at our Target Support Package TC2 requirements page here:

https://www.mathworks.com/help/releases/R2008a/toolbox/tic2000/index.html

For packages using more recent releases, refer to the following page:

https://www.mathworks.com/products/ti-c2000-microcontroller.html

After installing these packages, perform the following step to enable these components:

1. Open CCS, go to "Help->About->Component Manager->Build Tools->TMS320C28XX" and check "C2000 Code Generation Tools 5.0.0".

2. Still in the Component Manager, go to "Target Content(DSP/BIOS)->TMS320C28XX" and check "Texas Instruments DSP/BIOS <5.32.01>". Save, exit, and restart CCS.
