V831 为什么OTG还是不能开机自动切换到HOST呢？

[ubuntu]

                usbc0:usbc0@0{
                        usb_port_type = <1>;
                        usb_detect_type = <0>;
                        usb_detect_mode = <0>;
                        usb_id_gpio;
                        usb_det_vbus_gpio;
                        usb_drv_vbus_gpio;
                        usb_host_init_state = <0>;
                        status = "okay";
                };

***usb_port_type ***：

0 device only
1 host only
2 OTG

[ubuntu]

usb_host_init_state = <0>;

改为

usb_host_init_state = <1>;

搞定了！

usb_host_init_state：

In host only mode, host port initialization state; 0 do not initialize; 1 initializatie USB
