Compiler/TM4C1292NCPDT: ROM functions does not have any occurence

Part Number: TM4C1292NCPDT


Tool/software: TI C/C++ Compiler

On my code, when I use ROM functions, it does not have any occurrence. I believe this is the reason that my code does not execute. It builds ok and it debugs ok but the board seems to be blank. I have added TARGET_IS_TM4C129_RA0 and PART_TM4C1292NCPDT and included the driverlib. It only happens to this project. On other projects, it works fine.

    Hello Emem,

    For one, you should be using MAP_ functions rather than ROM_ functions so DriverLib will direct the firmware to use either ROM or updated DriverLib functions. To do this you need to include the rom_map.h file.

    For two, there is not a lot of detail to go on here. Can you provide details on what your list of #include files are, what ROM API's you are calling, and screenshots of what your CCS project property pages look like for the following pages:
    - Project Properties -> Build -> ARM Compiler -> Include Options
    - Project Properties -> Build -> ARM Linker -> File Search Path

    You can attach Screenshots by clicking 'Use Rich Formatting' and finding the picture symbol on the post box toolbar.

    Here is a screenshot of my timer.c code

    And here are the include options and file search path. 

    The weird thing though is I used the same timer.c file in another project and it worked ok. I already checked that my build settings were the same.

    Here is a screenshot of the timer.c file in another project.

    Note that the text is also a different color, which implies that ccs is recognizing them as different syntax. The first one (pink) being functions and the second one (blue green) being others.

    Also, if I hover over the ROM function on the second picture, it shows the macro declaration but not on the first.

    Hello emem,

    On your include options where you manually added the link for C/ti/TivaWare.../driverlib, you should not have the DriverLib portion. It should just link to the entire TivaWare folder. That's how all our example projects are setup. I think that would be the source of the problem because it is likely trying to access C/ti/TivaWare.../driverlib/driverlib/rom.h which wouldn't exist.

    You mentioned "I have added TARGET_IS_TM4C129_RA0 and PART_TM4C1292NCPDT" - just want to make sure you meant that you added these to the Predefined Symbols list in the project properties right?

    And yes I would expect the text to be a different color when it is setup correctly. You also should be able to hit F3 and have it bring you to the function definition in ROM.h.
