Regarding booting 440 gr board / ibm emac driver

Regarding booting 440 gr board / ibm emac driver

[Kiran Kumar.A]

Hello Benjamin,
This is kiran here. I'm working on 440GR (Yosemite) board to boot linux-2.6=
.13.4.
Everything works fine execpt for MAC address. I saw the code in arch/ppc/pl=
atforms/4xx/yosemite.c; the code to copy the MAC addr from board info struc=
ture seems to be in place. I am  using IBM emac driver written by you.
Linux boots up fine and  in the booting messages , I see that the MAC addr =
is displayed as all zeroes. Also, the ifconfig displays the MAC address as =
all zeroes.=20=20

Could you please throw some light on the same.=20
What could be the issue? Do we need to modify the driver for MAC address is=
sue??


regards,
kiran

First, check that the code which copies MAC address is actually 
executed. Second, check _what_ is being copied by this code. Maybe 
board info structure contains zeros.

No, you don't need to modify EMAC driver.

Don't use old code. Please use the current version.

Just use current code. You can find ready to  run  binaries  and  the
corresponding sources (git repository) on our server:

ftp://ftp.denx.de/pub/u-boot/images/amcc/yosemite/u-boot.bin
ftp://ftp.denx.de/pub/linux/images/amcc/yosemite/uImage
and http://www.denx.de/cgi-bin/gitweb.cgi?p=linux-2.6-denx.git
(git tag "DENX-2005-12-03-2208" or later).

Best regards,

Wolfgang Denk

Just a quick note, since you mentioned using 440GR (Yosemite): Yosemite is the 
eval board for the 440EP and Yellowstone is the eval board for the 440GR. 
Images for both boards are available at the site referenced by Wolfgang.
