MATLAB: Am I unable to generate code if I specify a board string name that contains special characters during the Code Composer Studio setup for the Embedded Target for TI C6000 DSP

I am unable to generate code if I specify a board string name that contains special characters during the Code Composer Studio setup for the Embedded Target for TI C6000 DSP.

The name of my board contains characters such as "=", "%", "|", "'", "|", ":", and ";". I enter the name of my board in the Code Composer Studio setup and try to build my model using Real-Time Workshop. However, after doing this, the build process is not able to complete.

Several special symbols are not allowed in the Code Composer Studio board name string. These symbols cause various errors during code generation and/or corruption of your model's Real-Time Workshop Options. In particular, a recently-released emulator has a comma in its default board name. To work around the problem, rename your board in Code Composer Studio Setup. If your board is recognized by the board finder feature (via search by driver file name), your model will still work. If your models use "Manual" board selection, you must choose your board name again via Real-Time Workshop Options. The Embedded Target for TI C6000 DSP already handles spaces, which cause a similar problem. Spaces are replaced by underscores. The Embedded Target for TI C6000 DSP 1.1 (R13SP1) handles all these characters similarly.

First, make sure you correctly set up the C2000 Support Package by clicking the "setup" icon in the add-ons manager. This will take you through a series of steps to configure and locate installed TI products. This issue is most likely a result of MATLAB not being able to find a TI product such as TI C2000WARE. See the following link for short instructions on setting up the support package:

https://www.mathworks.com/help/supportpkg/texasinstrumentsc2000/ug/install-support-for-c2000-processors.html

Make sure the board is set up correctly in the Hardware Implementation tab of the model's Configuration Parameters. Make sure Code Composer Studio is correctly set up and configured for Embedded Coder.

If these steps do not resolve the issue, you can programmatically build and download the model:

>> open('ModelName.slx');
>> rtwbuild('ModelName')
>> command = 'C:\ti\ccsv7\ccs_base\scripting\examples\loadti\loadti -a -c=f28379D.ccxml ModelName.out';
>> [status1,cmdout1] = system(command);

Make sure to replace the model name and the path to loadti with the appropriate values. However, this will prevent running in external mode and communicating with Simulink, so it is best to fully investigate the previous options before using this workaround.

MATLAB: Do I receive an error in the CCS project setup process when generating code from a model that contains a DM642 EVM Video Capture and Video Display blocks in Simulink 6.2 (R14SP2)

The default memory model for TI C6000 Embedded targets is "Near_Calls_and_Data" as indicated in the TI C6000 compiler settings in the Real-Time Workshop Configuration Parameters dialog. For an algorithm only model, this provides the most efficient code execution. However, for DM642 EVM, addition of Video ADC / DAC blocks causes a link error with the default settings. Documentation on the Embedded Target for TI C6000 is missing information on setting the memory model configuration for models with DM642 EVM video capture and video display blocks.

Here is additional information:

When building a model with DM642 EVM Video Capture and Video Display blocks, this memory model should be set to "Far_Calls_and_Data" as follows:

1. Go to "Simulation -> Configuration Parameters -> Real-Time Workshop"

2. Select the TI C6000 Compiler option

3. Change the Memory Model to "Far_Calls_and_Data"
