Hi,

I need to develope an interactive boot sequence software, where I need to have an option for enableing/disableing of peripherals before the start of acctual application code. And I need to implement this on TMS570 USB development kit using CCS console. Please let me know how to proceed and prove me if there ara any application notes.

    Ajay,

    You want this interactive mode to work when CCS is use to debug your application?

    If this is the case, CCS supports all standard I/O routine to print message to the console and enter data via the console.

    When the standard I/Os routine are used, a section named .sysmem is created and has to be mapped to your internal RAM via the linker command file.
    Here is an example of linker command file:

    MEMORY
    {
        VECTORS (X)  : origin=0x00000000 length=0x00000020
        FLASH0  (RX) : origin=0x00000020 length=0x0007FFE0
        FLASH1  (RX) : origin=0x00080000 length=0x00080000
        FLASH2  (RX) : origin=0x00100000 length=0x00080000
        FLASH3  (RX) : origin=0x00180000 length=0x00080000
        STACKS  (RW) : origin=0x08000000 length=0x00001500
        RAM     (RW) : origin=0x08001500 length=0x00026B00

    /* USER CODE BEGIN (2) */
    /* USER CODE END */
    }

    /* USER CODE BEGIN (3) */
    /* USER CODE END */


    /*----------------------------------------------------------------------------*/
    /* Section Configuration                                                      */

    SECTIONS
    {
        .intvecs : {} > VECTORS
        .text    : {} > FLASH0 | FLASH1 | FLASH2 | FLASH3
        .const   : {} > FLASH0 | FLASH1 | FLASH2 | FLASH3
        .cinit   : {} > FLASH0 | FLASH1 | FLASH2 | FLASH3
        .pinit   : {} > FLASH0 | FLASH1 | FLASH2 | FLASH3
        .bss     : {} > RAM
        .data    : {} > RAM

    /* USER CODE BEGIN (4) */

        .sysmem  : {} > RAM

    /* USER CODE END */
    }

    You can also have a look to the following thread for additional details:
