2011-09-21 10:19:27 Problems with phy (micrel 8051)

Hello

I've got a problem regarding the ethernet connection of my custom board based on bf526-ezkit. As phy I'm using the micrel 8051MNL (mii mode).

If I interrupt the boot-sequence and use the u-boot ping everything works fine.

I'm also loading my uImage.ext2 via tftp successfully, what leads me to the conclusion, that my hardware design works. But after the kernel has booted, I'm not able to ping any host (beside localhost) anymore. Below follows my boot-sequence.
