EK-TM4C1294XL: Cant get the IP address of the Connected Launchpad

Part Number: EK-TM4C1294XL

Hi Everyone,

I am fairly new to microcontrollers but I have to use EK-TM4C1294XL for Serial to Ethernet(S2E) conversion as a part of my project. For S2E coversion as you might know a project named enet_S2E already exists in the library, I managed to built the project and run it without errors. The enet_s2e application hosts an embedded web server that provides a convenient configuration interface and to access that I need the IP address of the device(EK-TM4C1294XL)

To talk to the Launchpad I am using TeraTerm, for that I am using serial to TTL, RS232. When I run the serial to Ethernet application it shows on the TeraTerm terminal that its acquiring IP address but its never able to acquire it. My question is that how I can acquire the IP address ? Am I doing something wrong ?

I have attached a screenshot of CCS and TeraTerm terminal. I have also added a picture of the setup, how I connected all the cables.

Any of help of advice would be highly appreciated. Thank you

  • The enet_s2e example uses UART0 which is connected to the PC by the virtual COM port associated with the USB debugger connections and the on-board EMAC and PHY which is connected to the RJ45 connector on the bottom of your picture. You must connect the EK-TM4C129XL Launchpad to an Ethernet switch or hub so that it can obtain an IP address from the DHCP server. The connection you show to UART4 is not necessary.
  • Thank you Bob. It worked after I connected Ethernet to a switch.

    Now I am able to do Telnet but what I really want to do is to send packets using IP header. EK-TM4C1294XL is connected to a switch and the device I want to talk to is also connected to the same switch.

    So my question is that, is there any way of specifying the destination IP? Is there any other way of solving above mentioned problem ?

    Thank you

    Any help or advice on this would be very much appreciated
