This error originates from Code Composer Studio and not from MATLAB. There are two different versions of Code Composer Studio for C6xxx and C5xxx families of boards. For the boards from the C6xxx family, you need to have Code Composer Studio for C6000 series and for the boards from the C5xxx family, you need to have Code Composer Studio for C5000 series. If you have only one of these Code Composer Studio IDEs and try to open a project file for a board from other family, Code Composer Studio throws this error:
The build tools for this project cannot be found
You may get this error even though you have both the Code Composer Studio IDEs for the C6000 and C5000 series. For example, if you try to load the $MATLAB\toolbox\ccslink\ccsdemos\ccstutorial\ccstut_54xx.pjt project file which is a sample project file provided with MATLAB Link for Code Composer Studio (where $MATLAB is the root MATLAB directory), you may get the same error message as mentioned above if you do not have the drivers for the C54xx family of boards.
In order to avoid the above error message, please make sure that you have the proper version of Code Composer Studio IDE as well as the necessary drivers for the board that you are using.
