"eth1: Could not attach to PHY" on MPC8349e-MITX

[Timur Tabi]

The Freescale MPC8349e-MITX reference board has two TSECs, the second
of which (eth1) is attached to a Vitesse 7385 5-port switch.

Using the latest U-Boot, Kernel, and device tree, I cannot bring up
eth1.  When I try, I get this message:

[root@tintin root]# ifconfig eth1 up
0:01 not found
eth1: Could not attach to PHY
SIOCSIFFLAGS: No such device

Unfortunately, I don't even know what this means.

I believe my network configuration is correct.  Here's what ifconfig
says about eth1:

eth1      Link encap:Ethernet  HWaddr 00:E0:0C:00:8C:02
          inet addr:192.168.2.141  Bcast:192.168.255.255  Mask:255.255.0.0
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Base address:0x4000

eth1 does work in U-boot, so I know it can be made to work (and I know
the 7385's firmware is uploaded), I just don't know what needs to be
done in Linux.

Timur,

is it possible that the PHY adress doesn't match the one specified in
the dts ?

regards,
Andre

What part of the DTS contains the PHY address?  I have this:

	mdio@24520 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "fsl,gianfar-mdio";
		reg = <0x24520 0x20>;

		/* Vitesse 8201 */
		phy1c: ethernet-phy@1c {
			interrupt-parent = <&ipic>;
			interrupts = <18 0x8>;
			reg = <0x1c>;
			device_type = "ethernet-phy";
		};
	};

	enet1: ethernet@25000 {
		cell-index = <1>;
		device_type = "network";
		model = "TSEC";
		compatible = "gianfar";
		reg = <0x25000 0x1000>;
		local-mac-address = [ 00 00 00 00 00 00 ];
		interrupts = <35 0x8 36 0x8 37 0x8>;
		phy-connection-type = "mii";
		interrupt-parent = <&ipic>;
		/* Vitesse 7385 isn't on the MDIO bus */
		fixed-link = <1 1 1000 0 0>;
		linux,network-index = <1>;
	};

[PATCH] powerpc/83xx: Enable FIXED_PHY in mpc834x_itx and mpc83xx defconfigs

[Anton Vorontsov]

This is needed so that Vitesse 7385 5-port switch could work on
MPC8349E-mITX boards.

The FIXED_PHY driver isn't enabled in the defconfig. Following
patch should fix the issue.

^^^ That one. The Vitesse 7385 isn't on the MDIO bus, so the fixed
link (drivers/net/phy/fixed.c) driver is used for this ethernet port.

Your PHY is not on the MDIO bus, i.e. can not be programmed or queried.
Maybe your kernel lacks the mdio-less configuration ?

applied to merge.

Guys, can you put a [for 2.6.28] or something if a patch is intended  
for .28.. this way I hopefully pay a bit more attention.
