Tool/software:

Hi Team

I am working TM4C1294 EVK where I could able to up the Ethernet with the demo codes like enet_io 
but when i put the same code in actual project board (TM4C1294NCPDT) ethernet not getting even the it is not enumerating in the laptop
As of now hardware connection have been verified 
can you please suggest any changes to be made in code for the controller (TM4C1294NCPDT) 


please help me to solve this issue

    Another problem in this chips there is no MAC programmed So i program the mac using Uniflash  tool Whether it may cause any problem in working of the Ethernet ?

    Yes, you must have the MAC address in order run Ethernet applications. If you have successfully programmed the MAC address then they are stored in USER0 and USER1 registers. Why don't you verify if the MAC address is programmed by checking the USER0/USER1 registers. See below screenshot. Of course, you can use Uniflash to read these two registers too. Confirm if the values stores at these registers match what you programmed. If the registers are programmed  and the Ethernet example still does not work on your custom board then you need to check your board for the Ethernet interface. Compare your Ethernet interface schematic with the TM4C129 System Design Guideline at section 4.1. Make sure you have the correct connections between the PHY, transformer, ESD diode and RJ45 and all the resistors are of correct values. The RBIAS pin must be properly connected to ground through a 4.87k resistor.

    Any changes to be made in this lwipopts.h file ?

    There is no need to change lwipopts.h file if you are running the same example. 

    I will suggest you use WireShark to check traffics between the MCU (acting as a server on enet_lwip example) and the client (the browser running on your PC). First capture Wireshark by running the example on the LaunchPad so you have a good reference to compare with.
