Hello, I'm trying to port U-Boot 2010.09 to Cogent CSB737 board. It has an ATMEL At91SAM9263 uC and a SMSC LAN8700 PHY. U-Boot already runs quite well, but with networking it has problems.
U-Boot detects the PHY and is able to send packages over LAN, but do not receives any packages. What could be the problem?
