Do you have a working Linux kernel with a working network interface ? The Linux and U-Boot macb driver and PIO configuration is very close, and if you manage to make it work under Linux you'll probably have little trouble finding out the problem. > Olimex was kind enough to make Uboot nandflash build working with there > board, And deliver sources I cant compile, due to an error: Hardware > float vs software float.

Does the board send anything at all ? Try sniffing the net wire (using tcpdump for example). Also, what cross chain are you using ? I have seen strange network errors when using recent compilers which after investigation were -Os optimisation errors. (using the latest CodeSourcery toolchain for example). > Is there someone out there how has the MII mode working? If I'm correct, Olimex has. So closer inspection of their code may reveal some information.
