emac driver broken in 2.6.12.2 ?
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 ? emac: IBM EMAC Ethernet driver, version 2.0 Maintained by Benjamin Herrenschmidt benh at kernel.crashing.org 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) cheers, peter - Supercomputing Systems AGphone: +41 (0)43 456 16 31 Peter Fercherfax:+41 (0)43 456 16 10 Technoparkstrasse 1 email: peter.fercher at scs.ch CH-8005 Zuerich url:http://www.scs.ch http://www.scs.ch/ - -- next part -- An HTML attachment was scrubbed...

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

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 -Original Message- From: Josh Boyer [mailto:jwboyer at jdub.homelinux.org] Sent: Montag, 19.

Message emac: IBM EMAC Ethernet driver, version 2.0 Maintained by Benjamin Herrenschmidt benh at kernel.crashing.org eth0: IBM ema c, 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) 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 -- next part -- An HTML attachment was scrubbed...

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. josh

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