USB0 host test mode on Jetson Xavier NX

USB0 interface on Jetson Xavier NX is device mode,But I want to use usb2.0 Host Mode test on usb0,How can I do?

Hi

USB0 on Jetson Xavier NX is as device mode because it can’t supply VBUS to external.
USB0 can config as host mode, But you need supply power to external USB device by other way.
Please refer to the below document for porting USB host mode.

Hi

You could also do USB eye-diagram measurement when USB0 in device mode.

I just only want to use host test mode on USB0,So I don’t need VBUS because there won’t be any devices connected to the module in test mode,Isn’t it

it’s fine, So you need config it following adaptation guide…
