MATLAB: Do I get errors when building a model for the TI DSK C6711 Board using the TI Developers Kit 1.2 (R12.1)

codecomposerdeveloperkitlinkrtdxstudio

Why do I get errors when building a model for the TI DSK C6711 Board using the TI Developers Kit 1.2 (R12.1)?

I have a very simple Simulink model that runs fine. When I try building the model to the C6711 Target, however, I get the following error message from Code Composer Studio:

 undefined                        first referenced

One reason that you might be getting this error is because you do not have the DAC and ADC C6711 Blocks in your model. You should have these blocks in your model, even if you are not using them, in order to avoid the errors above.

MATLAB: Do I get errors when I try to build the Simulink model containing RTDX blocks using the C6701 simulator in the Code Composer Studio

Due to limitations in the simulator, you cannot use the CCS IDE simulator to build models containing RTDX blocks. You will need to have the actual board, the C6701 EVM or the C6711 DSK, in order to be able to use the RTDX blocks.

If you are still interested in using the RTDX blocks with the simulator, we offer the following suggestions.

NOTE: We have not fully tested and qualified this process and therefore we do not officially support this process.

To test using the simulator with RTDX blocks:

1. Please use the demo model 'c6701evmagc' as a reference to build your model containing RTDX blocks.

2. In the Code Composer Studio project, please replace the file:

 $TI\c6000\rtdx\lib\rtdxe.lib

with the following file:

 $TI\c6000\rtdx\lib\rtdxsim.lib

where $TI is the directory where Code Composer Studio is installed. (e.g. $TI can be: D:\Applications\ti).

3. Now build your model again

Once again, we are not aware of what issues or problems may arise if you use this process, and therefore you will have to troubleshoot it on your own.

MATLAB: Do I get an “entry point symbol _c_int00 undefined” error when building the model with Target Support Package TC2 3.1 (R2008b)

This can happen if the model's setting for Byte Order (aka Endianess) under "Simulation Configuration -> Hardware Characteristics" is incorrectly set to "Big Endian". If you change this to "Little Endian", the code should build successfully.

Note that Target Support Package TC2 3.1 (R2008b) supports the C2000 series chip in "Little Endian" mode only.
