hi,
 
i have problems with the IBM EMAC with 2.6.12.2 (the driver worked with
2.4.25)
running on ppc405EP octobus board. Cross compiled on x86 using the eldk-3.1
toolchain
 
any hints ?

I think you'd need to be more explicit about what "problems" means.
Hard to give hints with what you have here.

hi,

when you read the output I have pasted there you can see the following =
(also
in my origninal mail)
eth0: IBM emac, MAC 00:00:00:00:00:00

eth0: Found Generic MII PHY (0x00)

eth1: IBM emac, MAC 00:00:00:00:00:00

eth1: Found Generic MII PHY (0x01)


I think that this MAC addresses are crap (sorry if not formulated =
clearly
enough for you ;)
am I wrong ?

cheers, peter

Looks like your board platform file is not copying the MAC addresses into the 
ocp struct. Take a look at bubinga_setup_arch() in platforms/4xx/bubinga.c. 
Here ibm_ocp_set_emac() is used to copy the addresses.

Best regards,
Stefan

Are you sure that you?ve configured your ethernet driver? There is no MAC
address defined. And the PHY address is really located at 0x0 or 0x1? If not
you have also to configure the offset from which address the PHY routine
start in your board specific files like for OCOTEA reference board in
linux-2.6.12/arch/ppc/platforms/4xx/ocotea.c

Best regards,

David

No, you're not wrong.  My brain just didn't parse that as a problem with
the emac code itself.

Anyway, I think David and Stefan have pointed you in the right
direction.

Yep, he's got to configure the driver properly for his platform.
