lpc2378 and ethernet dp83848 problem

hi,
i am using a lpc2378 board with the ethernet PHY chip dp83848i,
And also i am using the sample code provided by keil for ethernet transmission..
In that code Tx_only part is working fine...
But in Rx_bouce, the interrupt which is to be generated when a packet is recieved by the lpc2378 from PHY, is not getting generated.And also the voltage of the signal out of PHY is 1.8volts with spikes at a range of 3.3v
In the Tx_only program we got the data out from lpc2378 at 3.3v
Dont know what the problem is!!!! why recieve part is not working!!!!!
Please Some one help me out...
its urgent.. THANKS IN ADVANCE..

  • Thank you for the response. This may not be possible since we are not sharing these ENET_RXD0 & ENET_RXD1 pins with any other function. Also, i wanted to clarify that this is the RMII output of PHY which is coming to LPC2378 at ENET_RXD0 and ENET_RXD1.Could there be any problem on the PHY chip side?
