Das U-Boot

Boot delay was an implementation that when you count down, like from four, six, four, three, two, one, and it'll start to full load.

You could break out of a system and get into the U-boot console, which used to be one of the attack methods, which we trained one year.

Then you can alter things in there and then continue the boot process to gain some level of access.

In this particular case, when it boots up and it hits the boot delay, if you hit the enter key, instead of breaking out into the U-boot console, it reboots.

So it

doesn't work.

If you want to do something specific, you have to halt it at a specific spot because memory is always changing.

The cool thing is the boot delay goes into a four-second count.

Let's see.

What is it, what is, what is that thing called? Uh, U-Boot.

Well, a lot of them run u-boot, and there's like three different ways for u-boot to inform the kernel about what device tree it should use.

And oftentimes you will see that like the vendor image ignores that and just sets it because the thing that u-boot thinks does not match what's actually on the hardware, which does not match what their special kernel version thinks needs to be there.
