Hi,
I made a small change in arch/ppc/platforms/85xx/mpc8540*c . I changed the
phyid value of TSEC1 to 4 and TSEC2 to 5. And it started working.

RE: Gianfar eth driver on 8540 ppc - for 2.4 and 2.6 : different outputs -
i have made some progress.
Hi,
Finally i have reached a position, where the PHY is detected . Now i am
using kernel version 2.6.14.4 and the gianfar_driver and phy driver seem
to be ok
But my problem now is after the PHY is detected (correctly) I don't get
messages like Speed, Full or half duplex, link is up etc.
This means that the driver is not completely up, right ?
What might be the problem ?
I am loading gianfar driver as a loadable module, but the marvell and
generic phy driver are built into the kernel.
This is my output :
/ # ifconfig eth0 172.28.8.254 up
eth0: PHY is Marvell 88E1101/88E1111 (1410c62)
But after this no output, like Speed, etc.
I checked the code, this info is in a function , gfar_phy_change which
inturn is setup in a PHY change work queue called INIT_WORK. All of this
code is in
drivers/net/gianfar.c

This seems to me it is a old board from GDATECH . Data sheet not available

Can you quickly check if you have the right phy id written in your
platform file for your board?

Hi,
Downloaded 2.6.16.26 and booted up and got this :

I had enabled all the PHY devices in .config and also tried
only with Marvell phy enabled.

It looks like your 2.6.12 kernel isn't handling the PHY
correctly.
I'd recommend upgrading to something newer which has the
phylib
(can't remember which 2.6 that went into).
