    Attached document Pg 179 Section 7.5 has description of linker command file syntax.Even though document mentions C28x it is applicable to TI linkers in general

    I had got few application examples with EVM DM6467 board. I have imported led application project to CCS V5. Under properties of the project, I have used "DM6467.cmd" for led application. 

    I have converted "led.out" to "led.bin" through ccs compiler.

    I had put the "ubldavinci.bin" on nandflash of EVM DM6467 board using "nand_flash_writer.out" in CCS v5.2 and I have placed the "led.bin" under application block. this is not executing. Under "emulation mode" this application will work but under "nand flash boot mode" this application will not work. 

    The message seen under console while writing "ubldavinci.bin" and "led.bin" to nandflash are as follows:

    Hi Rajesh,
    The "led.out" file is required to debug the code and led.bin is required to flash into NAND flash/any media.

    Hi Titus,


    1.    I downloaded the UBL” flash-utils-dm646x.tar.gz”
    2.    Using Code Composer Studio V6.0, I generated “ublDaVinci.out” file.
    3.    I generated “ublDaVinci.bin” file using  Code Composer Studio V6.0
    4.    Using NAND flash Writer Utility available in the ” flash-utils-dm646x.tar.gz , I have downloaded “ublDaVinci.bin  file to NAND flash.
    5.    The “ublDaVinci.bin “ file generated by CCS V6 didn’t work.  Then I tried with CCS V5.7 to generate “ublDaVinci.bin “.  Still it didn’t work.
    6.    Then I tried with the utility programs available with the ” flash-utils-dm646x.tar.gz” to generate “ublDaVinci.bin “  file.   Referred “EVM6467T installation guide”.  This “ublDaVinci.bin “ file, I downloaded to NAND flash and it worked.
    7.    I am writing No OS based application programs, hence I would like to generate .bin files directly using CCS.
    8.    Could you please help me, why the .bin files generated by CCS is not working with NAND flash.
    Thanks,
    Rajesh
