7. Umount the SD to ensure all the data has been saved to SD Card.
[root@COMX-P2020 root]# umount /dev/mmcblk0p1
[root@COMX-P2020 root]# umount /dev/mmcblk0p2
8. Add U-boot code to the SD Card.
 This step is not necessary if the user doesn't want to boot from the SD Card.
 To boot from the SD Card, the user must make sure that P2020 must be version
2.0 or above or it can not boot from the SD Card.
 To boot from the SD Card, the user must fdisk and format the partition at SD Card
as above steps at first. The first partition of SD must be FAT16, and its size must
less than 2GB.
 Please run following command:
[root@COMX-P2020 root]# umount /dev/mmcblk0p1
[root@COMX-P2020 root]# umount /dev/mmcblk0p2
[root@COMX-P2020 root]# cd /boot_format/
