TPS65987DDJ: Windows 19H2 HLK test failure

Part Number: TPS65987DDJ

Hi, everyone,


We're designing PC using TPS65987DDJ,
OS: Windows 10 (19H2)
Base FW: F807.12.37

and now, we've faced the problem about HLK test:

Fail:  UCSI Power Direction Role command - Reset on PPM-Reset
Fail: UCSI GetPDOs, partner Source Capabilities

Have you heard concerned problems?


By the way, we passed same test by our product using TPS65987DDH.

OS: Windows 10 (19H2)

Base FW: F707.10.05

So we wonder if there're any countermeasure uncontained in DDJ FW against 19H2 HLK test.

Best Regards,

    Hi Maurice,

    Would you be able to share your UCSI test logs for each failure? Also, if you have a logic analyzer, could you capture the I2C communication between the EC and our PD controller during these commands? Finally, if you could share a CC capture between the port under test, and the UCSI tester during each of these UCSI tests. Having these three pieces of information should help us solve the issue.

    Hi, Adam-san,

    >Would you be able to share your UCSI test logs for each failure?

    > Also, if you have a logic analyzer, could you capture the I2C communication between the EC and our PD controller during these commands?

    I sent your colleague Yone-san these log files (HLK, I2C, USBPD)

    about these 2 failure:

    Fail:  UCSI Power Direction Role command - Reset on PPM-Reset
    Fail: UCSI GetPDOs, partner Source Capabilities

    So please confirm these files.

    About HLK log file, this software is available.

    Please click the link "Windows HLK, version 1903".

    Best Regards,
