Hi, My mpc8270 board use three ehternet ports at FCC1,FCC2,FCC3.it is work well at FCC1.When I use port FCC2, I found out the u-boot is not receiving packets (It's sending correct packet when i use ethereal for sniffing). When trying "ping", it generated an ARP packet first, the other host replied with , but the board never seems to receive it(set printf at function fec_recv() /cpu/mpc8260/ether_fcc.c ).all three ethernet fcc ports initiailze is same.Do I miss something?thank you for your suggestion,my config file config FCC port parameter as follow:

Hi Jie,
I don't have any good insights, but some things to try: * Are you sure, positive, double checked and had a co-worker check that your clock input for FCC2-Rx is configured properly? 1) Which CLK input is used? 2) The port/pin configuration initialization in u-boot? 3) Your hardware (traces) actually connect the right pins?
* Does FCC3 work?
* If you turn off CONFIG_NET_MULTI and only use FCC2, does it work?
* If you turn off CONFIG_NET_MULTI and only use FCC3, does it work?
Good luck, gvb
