eth0: Could not attach to PHY

Hi All,
i have a board with MPC8555 processor
uboot version 1.1.6
linux kernel 2.6.19-rc5
ltib version: 6.2.2-sv
gcc 3.4.3

it boots successfully
i want to upgrade my linux kernel to 2.6.27
i upgraded the following:
ltib version 8.1.2-sv
gcc 4.1
linux kernel 2.6.27
& i kept the uboot with the same version 1.1.6

the kernel booting stucks as follows:

******************************************************************************

i have seen this error message across the mailing list but i reached nothing,
i m sure the dts is correct since i boot kernel version 2.6.19-rc5 successfully
i did not change the dts & ikeep it
is there any hint to solve this bug?

thanks in advance for ur help

You probably need to add an mdio node to your device tree and add a phy-handle to the ethernet node. See powerpc/boot/dts/mpc8555cds.dts for an example. (Look at the mdio@25520 and ethernet@24000 nodes)

Hello wael,

[...]

Here is your problem. For some reason, your network driver couldnt find the PHY ... Maybe there is something changed between 2.6.19-rc5 and 2.6.27.

and so, there is no network device ...

I have no 85xx board, but maybe following commit is something for you:

gianfar: Convert gianfar to an of_platform_driver

Does the same for the accompanying MDIO driver, and then modifies the TBI configuration method. The old way used fields in einfo, which no longer exists. The new way is to create an MDIO device-tree node for each instance of gianfar, and create a tbi-handle property to associate ethernet controllers with the TBI PHYs they are connected to.

If you have a board which is not an evaluation board please check you phy address.

first of all,thanks Heiko for ur reply.
but i m afraid that i understand nothing from ur answer, can u give me the steps to do ur suggestion?

is ur suggestion is about to change the device tree of my board? Here is the dts file of my board, if so what are the modifictions i have to do to execute ur suggestions

Change compatible to "gianfar-mdio".

"fsl,gianfar-mdio"

Hi
The device tree format has changed from linux-2.6.24. You need to port the U-Boot to the latest version. Even I faced the same issue.
