Newby trying to get Ethernet going on MPC83xx series device.

[Dushara Jayasinghe]

Yes I now base it on mpc834x_mds.c and it works (almost) :-(

The devices are successfully probed, but I'm getting this error on the debug console:

[    7.119389] mdio at 24520:00 not found
[    7.161370] eth0: Could not attach to PHY
[    7.209600] IP-Config: Failed to open eth0
[    7.258879] IP-Config: Device `eth0' not found.

My mdio & Ethernet nodes are as follows (commenting out device_type below is an experiment)

		mdio at 24520 {
			/*device_type = "mdio";*/
			compatible = "fsl,gianfar-mdio";
			#address-cells = <1>;
			#size-cells = <0>;
			reg = <24520 20>;

			phy0: ethernet-phy at 0 {
				interrupt-parent = <&ipic>;
				interrupts = <3 8>;
				reg = <0>;
				device_type = "ethernet-phy";
			};
			phy1: ethernet-phy at 1 {
				interrupt-parent = <&ipic>;
				interrupts = <3 8>;
				reg = <1>;
				device_type = "ethernet-phy";
			};
		};

		enet0: ethernet at 24000 {
			cell-index = <0>;
			device_type = "network";
			model = "TSEC";
			compatible = "gianfar";
			reg = <24000 1000>;
			local-mac-address = [ 00 00 00 00 00 00 ];
			interrupts = <20 8 21 8 22 8>;
			interrupt-parent = <&ipic>;
			phy-handle = <&phy0>;
			linux,network-index = <0>;
		};

		enet1: ethernet at 25000 {
			cell-index = <1>;
			device_type = "network";
			model = "TSEC";
			compatible = "gianfar";
			reg = <25000 1000>;
			local-mac-address = [ 00 00 00 00 00 00 ];
			interrupts = <23 8 24 8 25 8>;
			interrupt-parent = <&ipic>;
			phy-handle = <&phy1>;
			linux,network-index = <1>;
			phy-connection-type = "gmii";
		};

Any clues as to where I should start looking?

BTW, I assume CCing all those who replied to me is accepted/expected conduct or should I avoid this and just write to the list?

Also is top posting ok? I haven't figured out how to enable '>' on bloody Microsoft Outlook, for incoming plain text messages.

Thanks again for all your help.

Probably better would be to check the board file for  mpc834x_mds.c

I mean just cross that you probe all the buses which are on the device.
What is fsl,pq2pro-localbus? Do u have such node in dts as the
mpc8349_itx has.
