simulink build for C2000 package

Hi, all:

These days I have met a very strange problem when using the embedded coder generation function for TMS320F28379D.

For a algorithm module packaged by S-function builder, the functional test has been past in the SIL loop. Then, I start the "Build, Deploy & Start" button to build and download the program to the 28379D device. But the test result failed, which have been verified in the external mode.

Then, I opened the project generated by Matlab with CCS manually, and build the project directly in CCS. With downloading the .out file generated by CCS, the test result passed!

I have found that size of the.out file generated by Matlab is different than that of CCS. So I didn't kown why this problem happened. My testing enviroment:

· Matlab R2019b,

· CCS V8.3.0

· ToolChain ti-cgt-c2000_18.12.2.LTS
