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,
