Hi all, 


I am trying to run a web server in MPC5748G Devkit. For this, I need a TCP/IP stack for which I have selected lwIP. I am yet to select the RTOS to be used. Considered candidates are FreeRTOS and eCOS.


lwIP can run on bare metal without having any operating system. I got an lwIP package ported for MPC5748G EVB from this community - MPC5748G ENET . It works perfectly in EVB and I can run an http webserver on it successfully.


Now I have to take this to Devkit. The relevant difference between the EVB and Devkit are:

1. EVB supports MII (by default) and Devkit supports only RMII.

2. EVB has dp83848c as the phy controller whereas Devkit has KSZ8081RNACA as the phy.


The ported lwIP package has the driver for dp83848c. I need the driver for KSZ8081RNACA.


Does anybody have this driver? Has anyone tried to execute lwIP in Devkit?
