[Gumstix-users] Confused about uImage, ramdisk.img, rootfs.img, and can't make ramdisk.img

[Stephen M. <mo...@st...>]

 

I'm trying to boot from compact flash, and am trying to build my own files
to load.

 

Using buildroot, I can build the uImage and the rootfs.img, but can't figure
out how to build the ramdisk.img.

 

I also don't really understand what is in the ramdisk.img, is that a subset
of what is in rootfs.img?

And we boot using the kernel in uImage, against the ramdisk, and then switch
the root to rootfs?

 

In buildroot, who do I ask it to make a ramdisk.img, is that the ext2 option
or something else in targets?
