They can. > eth0: CPM ENET Version 0.2 on SCC1, 00:d0:93:00:12:34 > eth1: FEC ENET Version 0.2, FEC irq 3, MII irq 4, addr 00:d0:93:80:12:34 Please be aware that both interfaces use the same MAC address. This is ok as long as you don;t try to connect bioth to the same subnet. > VFS: Mounted root (ext2 filesystem). > Freeing unused kernel memory: 40k init > init started: BusyBox v0.60.2 (2002.07.18-17:16+0000) multi-call SIOCADDRT: > Net > work is unreachable > > ******(What reason ? when this message output?) Well, it makes little sense to guess how you ifconfig'ed the interfaces, please provide more information. My bet is that you tired to run both ethernet ports in the same network, and that you're experiencing a conflict caused by two identical MAC addresses.
