Nothing error logs found during writing.

Below is one of my test case.

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

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

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