Unable to configure Ethernet_LDD (Processor Expert) in MII mode to send raw packets.

Hi All,     I am trying to implement an ethernet driver for sending raw packets using processor expert, and I found the Ethernet example in the freescale folder "C:\Freescale\CW MCU v10.5\MCU\CodeWarrior_Examples\Processor_Expert\Kinetis\TWR-K60N512\Ethernet". This essentially sends a packets and receives it in the tower board itself using internal loopback, to check if the transmission and reception are working properly. It is configured to use RMII interface. I need to configure it so that it works in MII mode. I changed the processor expert configuration for Ethernet_LDD for operation in LDD mode, changed the on board clock input to the PHY in TWR-SER board from 50MHz to 25 MHz, and tried to run it. The Frames are not being transmitted, and the interrupts and events are not even getting triggered even once even though they are all triggering in RMII mode. Is there something I have missed? I am attaching the Ethernet_LDD configurations for Processor Expert for RMII and MII. It would be great if someone could point out if there is a mistake in my configuration.



Thanks in Advance,
