Tutorial on uboot commands

Postby balanga » Wed Nov 01, 2017 12:00 pm

Can anyone recommend a tutorial on uboot commands and how uboot works in general?

I am aware of this site:-

https://www.denx.de/wiki/DULG/UBootCommandLineInterface

but that is more for reference than a tutorial.

I don't know of a good tutorial. I tend to work from a mixture of the denx web site. Then in uboot itself using "help" and "printenv". These last two will show most of what you need to understand.

What you soon learn, that that each uboot has different amounts of the *full* uboot installed. So not everything described on denx is typically installed. So as such a tutorial would be a bit hard to do, probably half the commands wouldn't work on half the boards ...

Well that's unfortunate. Thanks for the insights nonetheless.
