I have used control card tmsf2808 and working on digital power kit.

I would like to know what these error means.

    Arun,

    Your attachment does not have the complete project/all of the files required for us to try building it. In any case, it looks like you are importing a CCS 3.3 project (as I see a .pjt file in your attachment) into CCSv5 and building. If so, please make sure there were no issues during import and also that all required sources are added or linked to the project. If you look at the .pjt file you can see which source files are used in the project.

    The linker errors you are seeing is because main.c is referencing these symbols but the linker is not able to find definitions for them in any of the object files or libraries. A majority of those symbols are typically defined in the GlobalVariableDefs.c for your device. Make sure that C file is included in your project and getting built. There may still be a symbol or two coming from another source file so make sure you double-check that all required source files and libraries are properly set up.
