Part Number: TM4C1294NCPDT

I'm looking for some LwIP UDP server or client example based in FreeRTOS.

Does anyone have any tips? I'll appreciate any help...

Thanks,

    Hello Richard,

    Our Ethernet expert is out of office currently but will be able to comment on this later this week.

    Thanks, Ralph.

    Is TivaWare_C_Series-2.2.0.295, which includes LwIP-1.4.1, ready to use the Netconn API?

    I've seen some old posts saying that it's only possible to use the Raw API.

    Hello Richard,

    I am not sure 'only possible' is accurate. We only have example projects and such with Raw API in TivaWare, but I am not aware if there is a specific issue with using Netconn/Socket API.

    My colleague has done some initial investigations into FreeRTOS / lwIP so I want to defer to his current findings on this topic, he should be back tomorrow.

    Best Regards,

    I've seen some old posts saying that it's only possible to use the Raw API.

    For lwIP to use the Netconn API, a RTOS must be also present. With RTOS, both RAW and Netconn API can be used per lwIP documentation. With that said, we currently do not have any examples and support for using lwIP Netconn API. The examples we have in TivaWare library all use Raw APIs without RTOS.  Support for lwIP Netconn+RTOS may be something for us to look at but we don't have a timeline at this moment.
