Hi, everyone
I'm trying to connect ethernet with AT91SAM9260.
My board uses DM9161A as a ethernet transceiver.
The u-boot ethernet initialization routine runs auto-negotiation,
it works fine. Ethernet controller of AT91SAM9260
(MACB0) receives Auto negotiation completion bit
from DM9161A status register.
But status registor of DM9161A returns "Invalid link status",
so u-boot prints "eth0 link down".
When does the "invalid link status" situation happen?
How can I fix this problem?
I connected the ethernet with PC by cross ethernet cable.
Thanks in advance.
Best Regards,
J.Hwan Kim
