DM6437 NDK -"NO PHY CONNECTED" error

I have compiled NDK example (helloworld) successful,but when run the helloworld.out, stdout windows showed "NO PHY CONNECTED".

The version of  NDK which i installed is 2.0,stack architecture is different from old version of NDK.I have read porking NDK to different PHY guideline,but I still don't  understand where to modify the NDK source files.

I came to find that "NO PHY CONNECTED" was caused by the EmacPoll(), EmacPoll() called _HwPktPoll(), _HwPktPoll() check the mdioStatus which is generated by MDIO_timerTick..Although i connected the PC to DM6437,but I watch the MDIO_timerTick(), PHYSTATE is always PHYSTATE_MDIOINIT, so the RetVal is always PHY_ERROR.

thank u for answer,
