Boot is a common term used to indicate startup and other related processes.
Uboot is a proprietary term, indicating a software named uboot.

Question

I have a project like this. I need to burn boot. bin first and then uboot. bin. What is the problem? I have introduced two boot programs. I don't know why?

Answer

That is, you have a boot code before uboot. This code should be related to hardware.
However, I remember that most of these boards should be fixed directly without rewriting. Of course, the advantage of not curing is that it can be modified. The price is that if this part is broken, it may be necessary to go to the dedicated writing machine.
