Just a quick update ... I've now setup our board to boot entirely from NAND (UBoot -> Kernel -> UBIFS) so that I'm no longer using NFS (just to isolate any issues there). I am still *unable* to get a connection on either Ethernet port. *HOWEVER* ... I *can* ping my board from another PC on the network:- mpfj@mpfj-nanobone:~/uboot/u-boot$ ping 10.0.101.111 -c 5 PING 10.0.101.111 (10.0.101.111) 56(84) bytes of data. 64 bytes from 10.0.101.111: icmp_req=1 ttl=64 time=0.692 ms 64 bytes from 10.0.101.111: icmp_req=2 ttl=64 time=0.551 ms 64 bytes from 10.0.101.111: icmp_req=3 ttl=64 time=0.462 ms 64 bytes from 10.0.101.111: icmp_req=4 ttl=64 time=0.409 ms 64 bytes from 10.0.101.111: icmp_req=5 ttl=64 time=0.344 ms --- 10.0.101.111 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 3998ms rtt min/avg/max/mdev = 0.344/0.491/0.692/0.123 ms So I can't ping *out*, but I can ping *in* !! Note that I've only tried this ping test to/from eth0 ... I'll setup another box on the correct IP range so I can also test eth1. I've added my boot log below.
