RTOS/EK-TM4C129EXL: CC3120BOOST - Wi-Fi Enabled IoT Node not working

Part Number: EK-TM4C129EXL

Tool/software: TI-RTOS

Hello,

I just received 2 test kits:
EK-TM4C129EXL and C3120BOOST.

Im trying to test the TIDM-TM4C129XWIFI example but I'm not able. I know this example is for the EK-TM4C1294XL and not exactly for my launchpad but from what I have checked, the boards and the processors for that application are "identical".

I can compile the project (several warnings in the compilation) and program the EK-TM4C129EXL. But it gets stuck in the void function HttpSetup () on the LOOP_FOREVER () line; located in main.c. Follow the attached project.

wifi_node_station_tirtos.zip

Regarding the C3120BOOST I can't program it. I'm connecting it to BoosterPack1 in the launchpad. Is there any change that should be made to the card or can I not program it through this card? Follow the attached error print.

Here are the versions of the software I'm using:

CCS: 8.3.0.00009
UNIFLASH: 4.6.0
TI-RTOS: 2.4.0.10 (INCLUDED TivaWare_C_Series-2.1.1.71b)
CC3100SDK_1.3.0
XDCtools: 3.31.1.33

  • Hello Vinicius,

    The issue isn't with the TM4C device difference. The issue is with the CC31xx device difference. The TI design is for the CC3100, but you are using the CC3120. From what I see, the software for these are not completely interchangeable.

    We do not have a design or software for the CC3120. Instead I would recommend you look at the latest SimpleLink offerings. The MSP-EXP432E401Y LaunchPad should be a better fit if I remember right.

    Best Regards,

    Hello Ralph,

    Thanks for your answer! What a dumb mistake =/

    Is there a workaround hardware to comunicate with cc3120boost or a wi-fi hardware that is compatible with EK-TM4C board? I quickly saw that MCUs are very similar (MSP and TM4C) in this particular aplication

    If I use the MSP-EXP432E401Y LaunchPad will it work directly with cc3120 or do I need anything else like CC31XXEMUBOOST?

    By the way why or when do I need the CC31XXEMUBOOST?

    Regards!

    Hello Vinicius,

    It's not all hardware issues, the SDK for the CC3100 and CC3120 are different. We have the CC3100 working with TM4C, but not the CC3120 SDK because that is part of our SimpleLink portfolio and TM4C is not a part of SimpleLink.

    The MSP-EXP432E401Y + CC3120 SDK should work together but you can cross check with the WiFi guys at this forum: e2e.ti.com/.../968

    The CC31XXEMUBOOST was used as an adapter between our older EVMs which had EM headers to work with LaunchPads that have BoosterPack headers only. You won't need it.

    Best Regards,
