Hi friends,

            I am new for this platform and Looking for your Guidances !!..

   I start working on AM335x_starter_kit. I am able to boot Kit with uSD-card which I got  with Starter kit, but when

   I prepare new uSD-card using pre-build  images which I got with Development kit by running using "create-sdcard" script. I am not able to boot board with this card. Getting below message.


Using SDKv05.05.

In uSD-card Boot partition MLO, uImage,u-boot.img are present

In uSD-card root partition root file system is present.

But while inserting it on board it is not responding. Only "ccccccccccc"  string is appears.

    Vishal,

    The CCCCCCCCC output in the serial console means that no boot source was found and the board is waiting to boot from UART. The only reason for this I can think of is that something is wrong with your SD card.

    Do you run the create-sdcard.sh script with sudo from withing the <sdk_dir>/bin/ folder? Does everything complete correctly with no error messages?

    I know I suggested this in your other thread about the AM335x GP EVM, but can you try with a different SD card?

    Have you tried with a later version of the SDK? Version 05.05.00.00 is very old and I'm not familiar with its problems.

    Best regards,
    Miroslav

    hi Miroslav,

         I tried same with other card also but fail to get any thing on minicom.

         One more thing I observe when I am running "setup.sh" after creating SD card using

         given script. I am getting following message


    /////////////////////////////////////////////////////MSG///////////////////////////////////////////////////////////////////////////

    -------------------------------------------------------------------------------
    This step will set up the u-boot variables for booting the EVM.
    Becuase the not all AM335x devices have a NAND, the u-boot variables will
    be stored in uEnv.txt on the boot partition. U-boot will read this
    file on boot.

    Autodetected the following ip address of your host, correct it if necessary
    [ 10.217.16.117 ]

    Select Linux kernel location:
     1: TFTP
     2: SD card

    [ 1 ] 2

    Select root file system location:
     1: NFS
     2: SD card

    [ 1 ] 2


    This SDK supports both the AM335x EVM and the BeagleBone/EVM-SK.
    A BeagleBone/EVM-SK has been detected as attached to your host system
    Are you wanting to configure u-boot for this device?  An
    answer of 'n' will configure u-boot for the AM335x EVM instead
    (y/n) y
    The boot partition doesn't appear to be mounted on the host.
    If you're using a virtual machine, please ensure it has been imported to Linux
    Please ensure the boot partition is mounted and run setup.sh again.
    Press Enter to exit
