    Hi Sankar,

    As per the offline discussion you were not able to get the rootfs under "dfu util -l".

    I tried to boot in dfu boot mode and set the dfu_alt_info to dfu_alt_info_emmc. I was able to see the rootfs interface.

    Can you elaborate on the problem here?

    Regards,

    Karan

    Flashing images to eMMC using DFU:

    come to u-boot command shell and execute following command
    U-Boot # setenv dfu_alt_info ${dfu_alt_info_mmc}
    U-Boot # dfu 0 mmc 0

    From host PC DFU will be detected and execute following command
    $ sudo dfu-util -l
    dfu-util 0.9
