Trying to understand how a boot loader handles initrd/initramfs/ramdisk ...
I'm currently porting linux to a proprietary board, ARM based, which
already runs a -again- proprietayre monitor. Under this monitor,
to avoid re-doing everything, i've also written a linux boot loader,
which starts to work.
My machine is diskless, screen less, ... only a serial line for the moment.
I'm using kernel 2.6.4, cross-compiled on an intel linux box.
I encounter a few troubles with initrd and related stuff .
What i want to do is create my own file system (root) and make a ramdisk
with it, and use it right after booting with no other operation.
I've the gzipped ext2 image of this directory/file tree flashed on my board,
so i though it would be a good candidate to give it as an initrd image,
but i do not succeed yet to make it work and do not understand a few things :
checking if image is initramfs...it isn't (ungzip failed); looks like an initrd
But i don't even now what an initramfs is !? :confused:
Seems to be a new stuff in 2.6 kernel, but where is there a documentation on that ?
Thanks for any help, doc , links on these
