Hi,

We are trying to get linux 2.6.33 to work on the movidis x16 board. Main thing
missing is the addresses of the PHYs. Does anyone know those ?
Unfortunately I don't have physical access to the board so I can't just look
for the PHY components being used.

Thanks,

Peter.


Do you mean the Movidis x19 ?

Maybe. AFAIK ours is called x16, and uses a cavium octeon CN3860 chip.

We have 2 of these in our lab. They are running the old 2.6.21.7  from
the CnUsers 1.8.1  tool chain.
They are currently being used by other developers for some application
testing, but I can grab the serial console boot-up messages and send
them to you, if the PHY info is in there.

That would be helpful. Otherwise you could also try running ethtool on all the
interfaces. That should give you the PHY address as well.


I just found one of these. Current theory is that the PHY addresses are 0-7

I don't think the PHY numbers are printed anywhere.

You are right, it is called an x16. My memory is failing me, I should have looked at the machine first.

from dmesg:

cavium-ethernet: Cavium Networks Octeon SDK version 1.8.1, build 294
Interface 0 has 4 ports (RGMII)
Interface 1 has 4 ports (RGMII)
Interface 2 has 4 ports (NPI)

looks like the PHYAD field has what you are loohing for,

You may want to re-map the interfaces so that they show up in a sane order, there is a cluster of 8 ethernet ports, 4 per row. Right now on our boxes , eth0 shows up on the bottom row, second from the right.
