Hello,
In my board(MPC8248) i have u-boot-1.1.2 configured with FCC1 as configured ethernet port. i m able to download the kernel and ramdisk image from tftpboot. and after that i usually configure the ethernet port by assiging ips eth0:192.168.33.64 and eth1:192.168.174.231 ,subnet mask:255.255.255.0 and default gateway :192.168.32.47 eth0 and 192.168.174.47 eth1.
an after that i enable lo (ifconfig lo 127.0.0.1) option in kernel.
Now My requiremnt is to have both the ethernet port to be working physically. so i ping to both board ips(192.168.33.64 & 192.168.33.66). But what i found out is if FCC1 is configured as eth port at u-boot time then pinging will work untill FCC1 eth cabel is connected to RJ45 port.ie. cable connected at FCC2 port doesnot have any effect. and it seems to be both the port is dependent on the FCC1 port only.
Can anybody suggest what might be the issue?
