The default configuration on this board, on Type-C connector, is: - Dual Power Role (DRP), so set power-role to "dual"; - Vbus limited to 500mA, so set power-opmode to "default" (it means 500mA in USB 2.0). power-opmode is used to reconfigure the STUSB1600 advertising of current capability when its NVM is not in line with the board layout. On stm32mp15xx-dkx, Vbus power source of STUSB1600 is 5V_VIN (so add the vin fixed 5V regulator too). So power operation mode depends on the power supply used. To avoid any power issues, it is better to limit Vbus to 500mA on this board. ALERT# is the interrupt pin of STUSB1600. It needs an external pull-up, and signal is active low. USB OTG controller ID and Vbus signals are not connected on stm32mp15xx-dkx boards, so disconnection are not detected. Without DWC2 usb-role-switch: - if you unplug the USB cable from the Type-C port, you have to manually disconnect the USB gadget: echo disconnect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect - Then you can plug the USB cable again in the Type-C port, and manually reconnect the USB gadget: echo connect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect With DWC2 usb-role-switch, USB gadget is dynamically disconnected or connected.
