Hello, I am using HDMI 7" display with usb (i2c) touchscreen. When i plug the usb touch to the standard USB everything works, but i would like to use the micro USB OTG. I reconfigured the usb otg in script.bin to make it similar to standard USB:
[usbc0]
usb_used = 1
usb_port_type = 1
usb_detect_type = 0
usb_id_gpio = port:PH04<0><1><default><default>
usb_det_vbus_gpio = port:PH05<0><0><default><default>
usb_drv_vbus_gpio = port:PB09<1><0><default><0>
usb_restrict_gpio = port:PH00<1><0><default><0>
usb_host_init_state = 1
usb_restric_flag = 0
usb_restric_voltage = 3550000
usb_restric_capacity = 5
[usbc1]
usb_used = 1
usb_port_type = 1
usb_detect_type = 0
usb_drv_vbus_gpio = port:PH06<1><0><default><0>
usb_restrict_gpio =
usb_host_init_state = 1
usb_restric_flag = 0
But it is not working. The screen is blinking about each 5 seconds and on the dmesg there messages like that:
