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..

Thanks for your reply.. I will verify the Pins and Let you know.

kindly clarify whether a RMII signal of 3.3v is essential at the input of LPC2378 to generate the recieve interrupt. or what is the minimum voltage level needed to recognize a valid data.
Thanks in advance, Gayathri.k
look for holes near the track.
look for volts leaking away.
That will be clearly stated in the Datasheet!
Thank you so much for all your replies.. we got it working. Actually the problem is, there was a solder bridge shorting RX_D1 and RX_D0, which was pulling the voltage of the data down.
Thanks and Regards, Gayathri.k
