[U-Boot] AT91SAM9263 Board with DM9161A

[Josef Baumann]

Hi,

I designed a new AT91SAM9263 Board using the schematics of the Atmel 
AT91SAM9263-EK EVAL Board. I have a problem in the ethernet path. 
Running auto negotiation (Davicom DM9161A PHY) creates a connection with 
100MBit/Half - Duplex. With the original Atmel Board Full duplex  is 
possible. I tried this with U-Boot 2008/10 and Linux 2.6.24. TFTP from 
Host to our Board is ok, PING from Board to Host too, but not from Host 
to our Board.  Reading back the auto-negotiation advertisment register 
(ANAR 0x04) shows 0x00a1, when writing 0x01c1 before. What's wrong?

best regards

Josef Baumann
