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
