uClinux on MicroBlaze: Can't ping now

Hi everyone,

I've followed the instructions from John Williams and Jason Wu, and finally got uClinux-kernel booted on my Spartan-3E-Starter-Kit

However, there's no boot message on the terminal, I got just a login prompt when the kernel started: uclinux-auto login:

Anyway, the kernel still works. Then I tried to test the networking and followed the instructions here

There's no problem to ping it self. But I can't ping my PC, which is connected to the Eva-Board using crossover cable. There's even no ARP packets received. It seems that the RX- and TX-pins are not connected to the FPGA. Did I miss something?

Any help is appreciated.
