Part Number: TPS65988
Hi,
I've tried the FRS procedure with the phone that currently does not support it and our Bus-powered HUB implementation.
I was expected to see any PD FRS request is sent from PD to the phone or phone FRS reject answer while the Charger disconnection.
Unfortunately, when I disconnect the charger from Port2, the Phone connected to Port1 (in Sink mode/Charging), just disconnected from the USB due to the VBUS drop to low
and power up again in the Source mode after ~300-500msec.
Please see attached :

- PD FW state machine traces
- PD SW pjt & bin
- PD Parser traces and log
Thanks
