Dear Sirs

About TPS65982 configuration seting for Thunderbolt 3 application,

How to build TPS65982 SPI flash binary for Thunderbolt 3 application (for the following 2 case l)?

 

  1. 2 port TB endpoint design  (use INTEL AR 4C – 2 port TB)
    1. Bus power could provide 5V (LV) or 12V (HV) : power source
    2. Thunderbolt port  could swich up-stream / down-stream  (1-port up-stream / 1-port down-stream )
    3. DP port (1 port down-stream): DP source
    4. USB 3.1 Gen 2 (1 port down-stream): USB 3.1 source

 

  1. 1 port TB endpoint design (use INTEL AR 2C – 1 port TB)
    1. Bus power only accept the Host HV: power sink
    2. Thunderbolt port  only up-stream port

    Nat,
    Please try referring to the User's Guide for the TPS6598X-CONFIG Config Tool and follow-up if you have any questions after reading the document.

    Nat,

    In both cases, I suggest you start by using the "Load Defaults" option in the TPS6598X-CONFIG Config Tool. You will want to start by downloading the latest version of the tool from the website as it is updated frequently. As of writing this e2e post, the latest version is "slvc621g", v1p15 of the Tool using ver. 1p7p6 FW base image.

    You can either Load the TBT Dock from the TPS65982 configurations option:

    Or load the Intel Apex Creek, Bus-Powered Device External, or Bus-Powered Device Internal from the Reference Designs option:

    You will then want to modify the settings in each Tab on the left-hand side of the Tool to meet the needs of the application and match the HW on the PCB.
