DM9000A Hanging !!

Hi,

--- Quote Start ---

When I try to configure eth0, after having given eth0 a sane MAC address, the system hangs:

ifconfig eth0 up

same story with

ifconfig eth0 192.168.0.190

At first, please check the access timing of DM9000A. When I set these values according to the Wiki's recommendation,

  Slave Adressing : Registers
    Units : ns
    Setup : 0
    Read Wait : 40
    Write Wait : 40
    Hold : 0

the eth0 would not respond, but the system did not freeze. Now I set these values like

  Slave Adressing : Registers
    Units : ns
    Setup : 10
    Read Wait : 10
    Write Wait : 10
    Hold : 10
 

with 100MHz system clock.
