Linux communicate with lwip on the TM4C129EXL by RAW API

Hi, I am trying to communicate with LWIP on the launchpad, I found that the website could be set up by lwip and running over the ethernet, so I am thinking whether I could have a little program running on PC or Linux that can communicate with the LWIP. 

My objective is trying to use the launchpad to enable a firmware update over ethernet, just passing the firmware to the SD card and reboot, the launchpad installed the new firmware through SD card.

Any suggestion is welcome.

Thanks

Shan

    Hello Shan,

    The enet_lwip examples uses the locator API's so that the device can be queried.

    Hi, Amit, Thanks for your reply, I have looked into locator API,  its description said :

    //! This function prepares the locator service to handle device discovery

    //! requests.  A UDP server is created and the locator response data is

    //! initialized to all empty.


    I am trying to make it running a lwip on Linux and communicate with lauchPad using Raw API, so I can transfer data from linux to launchpad. I knew it is not related to TI product, but I am just trying to get some info, any software that can capture and send packets? I have tried with the Lwip website, no answer, I am trying a better luck here.

    can you help me to ask your colleague?  Any help will be appreciated.

    Thanks

    Hello Shan,

    If it is about some off the shelf software, then I am not aware of one.
