440GP "Ebony" boot problems

440GP "Ebony" boot problems

[Andriy Korud]

Hi,
I'm trying to boot original 440GP "Ebony" board wiath original IBM ROM
Monitor:
...
	440GP 1.18 ROM Monitor (02/11/02)
...

However I've discovered that it requires special image in KDI (Kernel
Downloadable Image) format. And it seems that the only way to make such
image is to use 'mkimage' utility from LynuxWorks which is not widely
available :-)
Can anybody help me with this?

thanks in advance,

P.S. For some reason I cannot replace ROM Monitor with U-Boot on this
board.

Huh? I'm away from my Ebony right now, so I cannot check which 
OpenBIOS version it has but I never heard about KDI. 

Image generated by the `make bzImage` in 2.4 or 2.6 official 
kernel should be bootable on Ebony with original IBM firmware.

Why do you think IBM firmware requires LynuxWorks special image? This 
sounds like a nonsense, frankly.

I also thought similar, but:

- make bzImage within stock 2.6.9 gives me zImage.elf
- when trying to boot Ebony with it I have:

Booting from [EMAC0] Ethernet 0   ...
Sending bootp request ...


Loading file "zImage.elf" ...
Sending tftp boot request ...
Not a valid boot image file

And I'm completely lost with this :-)

You should use arch/ppc/boot/images/zImage.ebony, not zImage.elf

Correct OpenBIOS image has "\0RPO" at the beginning.

Thanks,
the problem was buggy OpenBIOS v 1.18 (problems with EMAC).
After upgrading to 1.19 everything works fine.

thanks,
