Sequre S60P USB-PD selection

Open kabel42 opened this issue 3 weeks ago • 3 comments

Describe the bug

Software does not select higher Voltage after PD negotiation

To Reproduce Plug Iron in USB-PD Supply -> PD-Debug list Voltages but Iron only selects 5V

Expected behavior Iron selects Voltage that allows for max Power Sequre FW selects 20V

Details of your device:

  • Device: Sequre S60P
  • Release: v2.22D.442DBD98
  • Power adapter being used: Lenovo 65W

Additional context The check in https://github.com/Ralim/IronOS/blob/dev/source/Core/Drivers/FS2711.cpp#L180 can never be true for the voltage/current combinations of my supply. tip_resistance is fixed at 2 Ohm PD-Debug reports: 5V 3A -> 1 Ohm < 2 Ohm -> Ok 9V 3A -> 3 Ohm > 2 Ohm -> not used 15V 3A -> 5 Ohm > 2 Ohm -> not used 20V 3A -> 6 Ohm > 2 Ohm -> not used
