Connect LPC1768 to Ethernet via DP83848CVV

Dear All , I have designed a board based on LPC1768 and a DP83848CVV for Ethernet PHY interface. I have tested the connection with some libraries that using Keil Libraries such as - #include <RTL.h> - TCP_CM3.Lib - TCPD_CM3.Lib And its working fine. I can set an IP, connect to LPC1768 and send and receive data via LAN. But when I want to try using mbed Libraries like: - #include "mbed.h" - #include "EthernetInterface.h" And set an static IP for micro with following lines, I never get the reply from pinging the Microcontroller: “EthernetInterface eth; eth.init( "192.168.9.8", "255.255.255.0", "192.168.9.1" ); eth.connect();” I have used “TCPSocket_HelloWorld - main.cpp” project in mbed website but again it does not reply. I connected DP83848CVV as shown in bellow image to the LPC1768.

Could you please help me to find the problem? Thanks /media/uploads/epsdaq/new_bitmap_image_-2-.bmp
