    Nothing error logs found during writing.

    Below is one of my test case.

    root@beagleboard:~# upk
    updateing kernel...
    flush storage...
    root@beagleboard:~# cat bin/upk
    #!/bin/sh

    echo "updateing kernel..."
    cp -f /mnt/nfs/t/uImage /media/mmcblk0p1/

    echo "flush storage..."
    sync
    root@beagleboard:~# diff /mnt/nfs/t/uImage /media/mmcblk0p1/uImage
    Binary files /mnt/nfs/t/uImage and /media/mmcblk0p1/uImage differ
    root@beagleboard:~# umount /media/mmcblk0p1
    root@beagleboard:~# mount -t vfat /dev/mmcblk0p1 /media/mmcblk0p1
    root@beagleboard:~#
    root@beagleboard:~#
    root@beagleboard:~# diff /mnt/nfs/t/uImage /media/mmcblk0p1/uImage
    Binary files /mnt/nfs/t/uImage and /media/mmcblk0p1/uImage differ


    Thanks,
