Questions arising from burning QT system to development board with TF card

Qt_HuangZiHan

I started the development board by burning the QT system with TF card. When HyperTerminal started Uboot mode, this statement appeared (my PC is Windows 7 64 bits):Unknown command '-sdfuse' - try 'help'。
Input instruction

iTOP-4412 # -sdfuse flash bootloader u-boot-iTOP-4412.bin
Unknown command '-sdfuse' - try 'help'
iTOP-4412 # - sdfuse flash bootloader u-boot-iTOP-4412.bin
Unknown command '-sdfuse' - try 'help'

@Qt_HuangZiHan "-sdfuse" - this looks like a parameter and not a command. If sdfuse is a command then remove - in front of it.
Can you explain what you are using? What documentation/tutorial you are refering to?

I am using the TF card to burn the QT system. The PC terminal is Windows 7 64 bits.I first divide the TF card into four zones, and then copy four Ubantu mirrors on the PC side.Then connect the TF card to Ubantu.Then execute ". / mkuboot / dev / sdx" on the command line of Ubantu, so that a TF card that can be burned is successfully written.But this problem arises when Hyper Terminal starts Uboot mode.
The parameters of the development board are as follows:
CPU：Exynos4412，Quad core Cortex-A9，basic frequency is 1.4GHz-1.6GHz
This is my development board.

This development board company's website, manuals are all Chinese board, I do not know where to start.
