eth0 link is not ready in mx6q

pepsitha

 Hi all,
 
I meet a problem. In my customer board, referenced from sabreauto-ai board, the eth0 link is not ready. could some one give me some advice? I really confused for some days. the log is as below:
====log below======
root@sabreauto_6q:/ # eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=1:01, irq=-1)
ADDRCONF(NETDEV_UP): eth0: link is not ready
====log end========
when I input "busybox ifconfig", it print log as below:
root@sabreauto_6q:/ # busybox ifconfig                                        
eth0      Link encap:Ethernet  HWaddr 1E:ED:19:27:1A:B3 
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

it seems that no ip address is obtained.
However, If I use FSL official Sabreauto-AI referenced board with the same internet wire, it is ok and the board can access internet normally. log is as below:
root@sabreauto_6q:/ # eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=1:01, irq=-1)
ADDRCONF(NETDEV_UP): eth0: link is not ready

compared with official referened board, my customer board cannot print the log in red. we have not changed ethnet module, it follows offcial referenced board. could you give some advices please? Any advices are appreciated.. thx a lot.
