CCS/BOOSTXL-CC3135: Programming Device and SPI Connection with MSP432E401Y

Part Number: BOOSTXL-CC3135
Other Parts Discussed in Thread: CC3135, CC31XXEMUBOOST, MSP432E401Y

Tool/software: Code Composer Studio

Hi all,

To preface these questions, I am an absolute beginner to Code Composer Studio, TI products, and embedded programming in general.

1. When I connect my BOOSTXL-CC3135 to my laptop, the Resource Explorer Home Page on Code Composer Studio does not detect the device, despite the fact that the LEDs on the module light up. Do I absolutely need the CC31XXEMUBOOST to directly develop onto the CC3135, or is there a way I can do so without it?

2. I am currently trying to figure out how to interface my CC3135 (slave) and MSP432E401Y LaunchPad MCU (master) with SPI on Code Composer Studio. I found the "spi_master_legacy_polling" and "spi_master_legacy_interrupt" examples in Resource Explorer for the MSP432, but I could not find any SPI slave examples for the CC3135, both on Resource Explorer or anywhere else online. Does anyone know where I could find SPI slave example code for the CC3135? 

Thanks for your help!

    Hi Alec,

    The CC3135 device is a network processor only. It does not have an application MCU or a debugger on the BoosterPack. You must use this BoosterPack with a MCU, such as the MSP432, to run an application. The CC31XXEMUBOOST contains a debugger to enable flashing CC31xx BoosterPacks.

    The easiest way to flash required servicepacks, user files, and network configuration settings is with the CC31xxEMUBOOST. There is a way to use the debugger on another LaunchPad for flashing, but you will need jumper wires.

    The CC3135 requires a host driver layer on the MCU that works over the SPI peripheral. The Wi-Fi Plugin already supports this for the MSP432E4. Please start with the SimpleLink Academy for CC3135: http://dev.ti.com/tirex/explore/node?node=AHBlESkkFD5ButyeyFMytw__s6qGmnm__LATEST

    Best regards,
