[U-Boot-Users] Re: What does the Kernel get from U-boot ?

Hello Booters, Just a quick newbie-style question: what is passed between U-boot and the kernel? Just the bootargs env variable or is there any other (more intimate http://news.gmane.org/img/smilies/smile.png%22%3E relationship

between the two? What I am asking is,

what does the kernel get from U-boot aside from the location of the root filesystem? I guess the answer is 'nothing', but if it turns out there is more, I'd like to know =)

Hello Federico,

I think I can answer your question, but I need a bit more information first.

What U-boot passes to the linux kernel is architecture-dependent, as so many things are in this world. What kind of system are you working with?
