Hi CY Friend,
My customer has build a pcb of type c to dp dongle, but the aux and sbu has no signal. HPD line is 3.3V.
Can you give some suggestions on what we can do?
Is this observed even when connected to a Type-C notebook that supports DP and DP configure command is ACK'ed by dongle?
AUX lines are isolated using internal mux by default and connected only on DP configure success.
