      My project is based on reference project firmware CYPD3120-40LQXI_dp_dongle it partly works except the power charging.


      Below is the diagram. Before Samsung is plugged in the USB-C the MOSFET switch is off so when Samsung is plugged in the USB-C the Dp-to-HDMI converter and USB hub start working. But Samsung is a power source.


      I can use one of the GPIO P1.0 or P1.1 to turn on/off the MOSFET switch. I would like to turn on the MOSFET switch to charge the Samsung from the dc/dc power supply. Could you please tell me how I can send a command to Samsung to change to power sink?
