TPS65983B: TPS65983B Fails GRL PD Tests

Part Number: TPS65983B


We currently have a product failing the following PD tests at GRL:

TDA.2.2.3 BMC PROT SEQ DRSWAP: DUT fails to accept DR_SWAP to DFP when DUT is Sink/UFP. Sends wait when reject was expected.

TDA.2.3.1.2 POW SRC LOAD CP ACC: The SourceCap counter is not reset to 0 as it should after PR_SWAP.

TDA.2.3.2.2 POW SRC TRANS CP ACC: Same reason as 2.3.1.2

I have found a couple of similar issues, if not exact same issue in these forum posts:

TPS65983B: TPS65983B Does Not Pass Thunderbolt 3 (TB3) PD Testing !!! - Interface forum - Interface - TI E2E support forums

TPS65983B: TPS65983B certification issue in GRL C2 - Interface forum - Interface - TI E2E support forums

It appears that Intel should be aware of these issues and issue a waiver, but they have only responded on whether I have consulted TI.

Can you confirm that these failures are indeed known issues?

I can provide project file, GRL reports, etc. if needed.
