TPS65987DDJ: Windows 19H2 HLK test failure

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.

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".

Hi, Adam-san,

Thank you for your reply.

We've solved these 2 problem by EC.

So I'll close this topic.

Thank you for your cooperation.

Best Regards,
