I’m working on my jetson-xavier module based custom design board and stuck at usb configuration, need support.
My Hardware Design like this:
- USB0 (F12-F13) - USB2.0 Flash/Debug port (No Vbus & no Pd controller). Xavier should be device
- USB3 (G10-G11) - USB2.0 Interface to STM32, Xavier should be host & STM32 is device
- USB3.1 (K16-K17 & B16-B17) USB3.0 interface to Rock chip module (which as type C Phy)
Currently my device tree:

Can anyone spread some insight to configure device tree ?
Thanks,
