CCS/TM4C1294NCPDT: Effects of changes in device, TivaWare Library, and CodeComposer compiler, over the past 2 years.

Other Parts Discussed in Thread: CODECOMPOSER

Tool/software: Code Composer Studio

Hi, We have been using this chip for 2 years and I recall at one point learning that the rom_map.h file in the TivaWare Library could change depending on the Revision of the device.  Can you let me know if the file, that is, the functions contained in the ROM has changed in the past 2 years.

Also, I noticed there is a more recent CodeComposer than the one we are using.  Can you describe what changes there are in it and how that may affect software that was written 2 years ago.

Thanks,

Brian

    Brian,

    I am not sure which version of Code Composer Studio or the TI ARM compiler you are currently using. In general changes to the Code Composer Studio environment will not have an impact on your application. Changes to the compiler on the other hand can. In general our compiler for Cortex M is pretty mature so there would not have been a huge amount of change there. We have introduced new utilities (objcopy, objdump...) but that would not have an impact on your build. Each version of the compiler will contain an Open_Defects.htm and a Closed_defects.html that will show you the history of issues fixed and open issues.

    If you do run into an issue you can always configure your project to use the compiler that you are currently using. In fact the project will be set to use that version and if the newer version of CCS is able to find it then it will automatically use that version.

    I am not familiar with the rom_map.h file. However the last release of TivaWare was 2.1.4.178 just over 2 years ago. So if that is the one you have then there would be no change.


    Regards,
    John

    Thank you John.  Good to hear everything is stable and hasn't changed much.  I think we will be ok.

    Regards,
