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.

device connected and 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.
