TMS320F28069M: C2000 microcontrollers forum

Hi,

If I want to generate a heavy .hex for my device, how can I increase the "weight" of my file?

I tried creating an empty array, but without any results; somebody have any other tip I can use?

    Initialize the array ...

    volatile const long bigArray[10000] = { 0 };

    Thanks and regards,

    For the source file that defines bigArray, please follow the directions in the article How to Submit a Compiler Test Case.

    Thanks and regards,

    The linker removes bigArray because it is never read or written by any function in the program.  Add some code that reads and/or writes to bigArray.  Or, you can force the tools to keep it by adding this pragma ...

    Fullscreen
    1
    2
    #pragma RETAIN(bigArray)
    volatile const long bigArray[10000] = {0};
