"update.img" file saved, and the USB storage device must be in FAT32 format.

When starting the Device, the system automatically check if there is a USB storage device
connected and if there is any upgrade file, and if yes and the check result of the upgrade file is
correct, the system will upgrade automatically. The Uboot upgrade can avoid the situation that
