From: Yogesh Chaudhari on 30 Nov 2009 05:00 Hello, I am running linux kernel with rt patch on embedded board based on lite5200 eval board. From linux-2.6.31 release, in which the mdio patch has gone inside, �the fec ethernet does not come up on this board. I get the following message at startup: mpc52xx MII bus: probed mdio_bus f0003000: error probing PHY at address 1 After the bootup if I try to do a ifconfig I get the message: net eth2: of_phy_connect failed If I change the value of reg in dts file (lite5200.dts) to 0 then this ethernet comes up. However upto this kernel version, this was not required. Ethernet does not come up on board with original lite5200.dts file phy0: ethernet-phy@1 { �� � � � � � � � � � � � � � � �reg = <1>; �� � � � � � � � � � � �}; Ethernet comes up on board with this change phy0: ethernet-phy@1 { �� � � � � � � � � � � � � � � �reg = <0>; �� � � � � � � � � � � �}; Please let me know, if there is any change needed to resolve this or if this is a known issue on this platform. The .config is below.

This change in reg value was not required till 2.6.31. It is only after this version that the change is needed.

I have checked that the mpc52xx fec driver was changed from 2.6.31 version but I am not able to point where this error is coming up from and how changing the reg value in dts (which is not required till previous versions) is solving this. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
