CC3120: MSP432E401 + CC3120

Part Number: CC3120
Other Parts Discussed in Thread: CC31XXEMUBOOST, UNIFLASH, SYSCONFIG, , CC3135, CC3300, CC3301

HI TI,

I need to connect via wifi to a MSP432 similar to:
www.ti.com/.../CC3120BOOST
Option 1: CC3120BOOST + CC31XXEMUBOOST + MSP-EXP432P401R.
Basically I need to get it to a single bar that integrates it.

I don't understand why CC31XXEMUBOOST is necessary. I see that CC31XXEMUBOOST is a USB to UART 6 port USB transceiver board.

Thanks Very much! Best Regards!

    Hi,

    CC31XXEMUBOOST is not mandatory, but it is good to have. It can be used for uploading content of SPI flash at CC3120BOOST using Uniflash software. Using Uniflash you can upload ServicePack, webfiles or User files. CC31XXEMUBOOST good for RF testing using radio tools also. For mode details see swra569 and swru469.

    Hi Jan, 

    Sincerely, thanks very much!

    I have read the documentation you shared with me, but I still have some questions.

    I would not like to have connectors on my PCB to plug the CC31XXEMUBOOST.
    Can you suggest me a SPI programmer to program the serial flash directly (other than CC31XXEMUBOOST)?
    I think that to load the firmware image via UART only CC31XXEMUBOOST can be used. Because the Sysconfig will not recognize another USB-UART transceiver. Is it so?

    Can you suggest me some simple alternative for a small custom hardware.
    Of course I can always leave the necessary pins accessible and connect them to the CC31XXEMUBOOST via jumper cables.

    Thanks very much. best regards.

    Hi,

    If you don't want to another connector at your PCB, you may consider programming CC3120 directly from your dost MCU (if you have enough resources) using sl_FsProgram() API. Another option can be using EMBEDDED-PROGRAMMING (CC3X20EMBEDDEDPROG).

    You can use any SPI flash programmer with capability to program Macronix SPI flash at CC3120BOOST. I think TI guys tested with Totalphase Cheetah SPI.

    With CC3120 you cannot use Sysconfig image creator, but stand alone Uniflash software. You can set COM port for Uniflash via parameter, but issue will be reset (nHIB) control. Maybe you can control pins via power_on_com.py and power_off_com.py, but I never tested with CC3120.

    Btw ... what is reason for selecting CC3120? Maybe for new project may to be better CC3301 or CC3300. Be aware, that CC3120 and CC3135 have limitation in usage of the EAP security.
