5.20.6.3 Uboot Upgrading

Under the root directory in the USB storage device, there must be "u-boot.bin.img" file and
"update.img" file saved, and the USB storage device must be in FAT32 format.

Make sure the USB storage device is inserted; otherwise the upgrading cannot be performed.
When starting the Device, the system automatically checks whether 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 you have to
upgrade tTFTP when the Device is halted.
