在设备树里面,将dwc3 USB控制器配置成peripheral模式,系统启动的时候会将USB控制器设置为设备模式,并初始化gadget相关资源,若配置成了otg模式,则只会初始化gadget相关资源,不会将dwc3控制器切换为设备模式,此时dwc3控制器处于otg模式,需要切换为设备模式(只有处于otg模式才可以切换为主机或设备)。 // 切换为otg模式e...
1)首先根据"snps,dwc3"进行dts和driver的匹配,执行dwc3_probe() 在dwc3中先调用 dwc3_get_dr_mode()取得usb mode(dr_mode),这可以是otg、host或者device 3)然后调用 dwc3_core_init()初始化usb PHY interface和usb PHY,usb PHY的初始化参照第4节。 4)最后调用 dwc3_core_init_mode()初始化usb mode...
