I use the controlsuite routine 2837X_RFFT，the .cmd file is "F2837x_D_FPU_RFFT_lnk.cmd ", but if I want to load program to flash to ensure my program is still exist when I restart the power, and I also want to use the FPU, how to config the .cmd file?

    Hi,

    The cmd file "F2837x_D_FPU_RFFT_lnk.cmd " already supports FLASH configuration.

    Please select one of the below CCS project build configuration based on your need
    1) FLASH_FASTRTS or
    2) FLASH_TMU0_TABLES

    to program to FLASH. You need not add any additonal linker command file to the project.

    Please let me know if you need any other information.

    Thanks,
    Katta

    Hi Tianyi,

    1) FLASH_FASTRTS : This build configuration uses FPU Fast RTS library to perform some floating point arithmetic operation faster
    2) FLASH_TMU0_TABLES : This build configuration makes use of Twiddle factor tables stored in memory with TMU support enabled


    Based on this description, you can decide to use the suitable build configuration according to your application.
