I have a 820-3476 board that is not working with my thunderbolt to hdmi adapter.
PPVIN_SW_TBTBST - 0v
PP15V_TBT- 0v
PP3V3_TBTLC - 3.3v
Q3080 is showing 15v on both the gate and source. Q3005 has 0v on the gate (TBT_A_HV_EN) which looks to be the reason why the gate of Q3080 is so high.
Why is TBT_A_HV_EN not being created. Does my thunderbolt adapter need to be plugged into a tv for TBT_A_HV_EN to be present?
