Booting Ebony-evb with u-boot and linux-devel-sourcetree from Denx

Booting Ebony-evb with u-boot and linux-devel-sourcetree from Denx

[Markus Bernauer]

Hi all,

I am trying to boot my Ebony-evb with u-boot and a kernel image generated
from devel-sourcetree from Denx. It seems to me like the kernel image simply
ignores the parameters handed over by u-boot. I also found some earlier
threads
that  support my thoughts. Unfortunately I am bound to u-boot and I am
not able
to switch back to the native bootloader that comes with the evb. Has anyone
already a system up and running booted by u-boot? At first it does not
matter whether
the root filesystem comes from flash or over nfs. Any hints would be
appreciated.

Thanks in advance

Markus

If somebody has time to support u-boot properly, I'd be happy to apply
the patch to the ebony port.  The current port relies on OpenBIOS since
it gathers the MAC addresses from the defined VPD space.  Some people
run with u-boot/ebony, but I gather they just hack the MAC address
code and use the kernel cmdline option.

It would be nice if somebody submitted a patch to make it u-boot
friendly, it's just not high on my TODO list.

We also were trying to get this to work, however, the ebony setup ignores
the uboot parameters...so, unless you modify the code, you're stuck with
this...

However, you could configure the kernel with boot parameters hard
coded...that's what we are currently doing.
