Dear Grant,
Are you sure that the ethernet interrupt are correclty handled? It seems to me
that the oak board never answers.
Have you ever serviced correctly a interrupt on the PPC403?
Interrupt handling on the PPC403 is very different from other PPC-architectures.
If you have HW-debug possiblity through the JTAG, try to break on external interrupt
at address 0x500 and step through the interrupt code to verify that it works correctly.
Other idea: Do you need a byte swapping to set the controller TCP/IP-address/ethernet
adresses?
