Thanks for all your inputs folks.
Forcing the switch to operate in 100mbps mode on the said port and then
connecting the ROACH1 has solved the problem now.
I am super stumped by the problem - this board worked for close to 10 years
auto-negotiating and decided not to, last Friday!
Cheers,

Ramesh,
I've never actually gotten a ROACH to talk directly to a server. The
auto-negotiation in the NIC is not great.
You pretty much need a switch in-between. Which is why Jason recommended
using an old 100Mbps switch.
Regards,
James

Yeah, but as I say, this never fixed the 1Gbps problem anyway. Was a weird

I just tried this by putting a spare network interface on to 100mbps and also
forcing the ROACH1 eth0 to 100mpbs - this did not help. Looks like the ethernet
device on the ROACH1 is dead.
I used mii-tool to force 100mbps operation:
root@roach:~# mii-tool -F 100baseTx-HD eth0
root@roach:~# mii
Dear Ramesh,
Here is the link you can download and write the image to the SD card. If
possible use the 2GB SD card which is shipped along with the board.

Hi Indrajit,
Useful to know - I believe I do have our original ROACH1 image somewhere,
therefore I will try what you suggested.
Thanks!

Just to add to what Jason has said, older 100 Mbps switches are easy enough
to pick up secondhand on eBay and such, depending on where you are. They're
quite cheap.

Dear Ramesh Karuppusamy,
This kind of issues we faced several times, We use to do re-write the SD
card image. Then it gets resolved. If you want the image for the roach1
I can provide the same. Then you can copy your BOF and run your code.

This actually wouldn't work anyway (we tried it). Something is broken in that

Thanks Jason, I thought about it.
Since we are running the ancient Debian Etch on this unit, I have no access to
ethtool, with which I understand that you can switch to 100mpbs. Is there any
other way to force 100mbps operation?

Can you try it with a 100mbps link partner? ROACH1's PHY was notoriously fickle
at 1Gbps. We never did get to the bottom of it, even with Nat.Semi's support,
and switched PHYs on ROACH2.

Dear All,
I hope you are all staying healthy.
The gigabit ethernet on our ~10 year old ROACH1 board went silent all of a
sudden this morning. The ethernet port show no activity (the yellow LED
flickers very occasionally). On booting the unit off the SD card, and manually
bringing up the interf
