    I'm assuming that you are not using DSP/BIOS (let me know if you are).

    Here are the steps that you would need to do to convert your application to flash boot:

    1) Update the memory map in the cmd file: add FLASH and boot sections. For example:

     

       MEMORY
    {
        vecs:          o = 00000000h   l = 00000200h
        boot:          o = 00000200h   l = 00000200h
        IRAM:          o = 00000400h   l = 0000FA00h
        CE0:           o = 80000000h   l = 01000000h
    }

    2) Add the boot section that you are going to place your secondary boot loader at the cmd file. For example:

     

    SECTIONS
    {
        "vectors"   >       vecs
        "bootload"  >       boot
        .cinit      >       IRAM
        .text       >       IRAM
        .stack      >       IRAM
        .bss        >       IRAM
        .const      >       IRAM
        .data       >       IRAM
        .far        >       IRAM
        .switch     >       IRAM
        .sysmem     >       IRAM
        .tables     >       IRAM
        .cio        >       IRAM
    }

    3) Add your secondary boot loader code to the project that will load the program from FLASH to IRAM.

    4) recompile your project and burn it into the flash

    Please see the document Creating a Second-Level Bootloader for FLASH Bootloading on C6000

    You can just create it if you want.

     No, as I explained in my previous post. The changes are in bold.
