CCS/BQ79600-Q1: Connections for bq79600 ans tms570ls1224

Part Number: BQ79600-Q1
Other Parts Discussed in Thread: TMS570LS1224, BQ79600EVM

Tool/software: Code Composer Studio

Hai,

Currently i am working on BQ79600 for bring up, I am unable wake up bq79600 using SPI interface, Please Help me with connections from mcu to (TMS570ls1224) to bq79600.

Please let me know if any sample code with uart is avalible for bq79600

Thank You,

M. Poorna Chandu

  • Hi Poorna,

    Please see section 4.3 "Connecting the BQ79600EVM to TMS570 LaunchPad" of the BQ79600EVM user's manual. Latest is available on the Web: https://www.ti.com/lit/pdf/sluuc57 

    There are a couple of resistors that need to be populated, and other 2 that need to be depopulated when using SPI to be able to plug-in the EVM to the LaunchPad. These steps are defined in section 4.3 of the latest user's manual. 

     Regarding the UART code, this should be available on MySecure by the end of the week. 

    Best regards,

    Leslie

  • Hai Leslie,

    We populated the resistors as mentioned in the user manual, but unable to wake up the Bq79600

    Can u please mention the steps to follow to check from my side

    Please tell me from when the Sample code of Bq79600 will be available in mysecure(with uart interface)

    Thank You,

    M. Poorna Chandu

  • Hi Poorna,

    The sample code should be available already. Please let me know if you don't see it.

    Have you configured the jumpers on the board for SPI configuration? If you sent me a picture of your board, I can check it for you to make sure everything is setup correctly.

    Once you do that, next step would be to check the signals to see if the wake up pulse is being received correctly. For this, please probe RX pin and nCS pin with an oscilloscope or logic analyzer when you send the wake up pulse, and share the plot.

    Regards,

    Leslie
