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!
