2 Ethernet port operating in a PPC405EP system
Hi all, Sorry for such long e-mail. I am now working on a STB project, and our board is a IBM PPC405EP with 2 ethernet ports. U-Boot 1.0.0 and linux 2.4.20 (from MontaVista) is used and update is not recommended. Each ethernet port has a RTL8021CP PHY connected. Under u-boot environment, only 1 ethernet port is operating. But sometimes the port is not able to PING other PCs within the same subnet. Also some modifications are made (under bd_t) to let linux kernel fetch 2 different MAC address when boot into linux kernel. Error log (U-Boot): ## snip ## Hit any key to stop autoboot: 0 = setenv ipaddr 10.6.64.343 = setenv ipaddr 10.6.64.34 = ping 10.6.64.128 ENET Speed is 100 Mbps - FULL duplex connection the board holds here about several seconds ping failed; host 10.6.64.128 is not alive ## snip ## Under linux environment, 2 ethernet ports are operating. But sometimes only ethernet 1 is operating (by running a udhcpc, from busybox-v1.00-pre8); sometimes both are not operating. When ethernet 1 is operating (can fetch a IP address from DHCP server, say 10.6.64.111), then I assigned a static IP address (say, 192.168.1.120) and let the board PING to different subnets at the same time. But the ethernet 2 cannot PING out while ethernet 1 is operating ...
