Why FEC and SCC1 can not work at the same time?

Hello,every one
    Hello Wolf gang thank you for help!my ramdisk problem has passed!I use linux-2.4.4-2002-02-14 kernel and all is ok!but I dont understand why linux-2.4.18 is not ok.


Now I meet a new problem! it is very strange!
I want to use FEC(100M) and SCC1(10M) interface,but they can not work together.
     When I use ppcboot with CONFIG_SCC1_ENET defined , boot linux ,then SCC1 is ok,when I ping FEC (I config it ip address is 192.168.2.221) it displayed messaged "time out".
     When I use ppcboot with CONFIG_FEC_ENET  defined,  boot linux ,then FEC is ok, when I
ping SCC( I config it ip address is 192.168.1.198) it displayed messaged also "time out".

Can you someone give help?thank you in advanced! the following is the linux output:

Current config is PPCboot with SCC1 ,the result is eth0 can work but eth1 is bad!

Zhongqx,

Probably there some is initialization missing/misconfigured both in FEC
and SCC enet drivers for your board. Main candidates are I/O pins
configuration and/or clock selection.

It might look like I'm doing nothing, but at the cellular level I'm
really quite busy.
