In the case that the AM335x USB controller is always in host mode and the peripheral IC is powered separately (so negligible current draw), is there any reason using a logic gate to drive USB_VBUS high wouldn't work? What are the benefits of using a power switch IC to drive VBUS? T...

OTG 功能下,需要根据USB ID 脚去进行Device/Host 模式的切换;如果需要支持NULL 模式(既不加载Device 也不加载Host 驱动), 那么还需要VBUS 状态检测引脚。 涉及到的主要改动点: 代码语言:javascript 复制 在sys_config.fex,修改如下配置: usb_port_type配置为2,即OTG模式。
