Hi guys,

I was hoping to have gotten some form of comment by now...

Can anyone help out here, please?

Now, I'm seeing these boot messages:

f0010d40:00 not found
eth0: Could not attach to PHY
IP-Config: Failed to open eth0
IP-Config: Device `eth0' not found.

Previous mailing list discussions suggest that I use the correct PHY,
which I am sure about because my 8272-based board only has the one PHY
ie. PHY0 with reg =3D <0x0>.

Note the relevant parts of my Device Tree below. Currently, our PHY
attributes eg. 'auto-negotiate' are not changeable, so we aren't
actually using MDC+MDIO even the MDC+MDIO lines exist. Also, the PHY
interrupt line is not wired up. Hence the PHY0 interrupts field is <0
8> (or should it be removed altogether?).

I am usig FCC2.

What might I need to change to get the ethernet driver working?
