To support DRP, Power Data to 20V/5A, PR_Swap, Vconn_Swap.
We encountered three issues when connecting to U4 host(ASUS VivoBook S14)
- After PR_Swap (Sink -> Source), Rd still can be seen on CC.。
- After Vconn_Swap, building power contract with SINK port, TI 988DK seems not asserting PS_RDY and then result in Hard_Reset. (This seems only when enabling power data to 20V/5A, but it is not seen when 5V/3A mode.)
- After Vconn_Swap, Cable deosn't response to TI988DK's Source/VConn SOP’ packet. but Cable did respond to host's SOP’ packet.
Best,
Thomas
