After I update Jetpack4.3, I found the USB cannot work. Then I search the developer forums and found some topic about this issue.
I follow the topic to modify my device-tree and flash into my carrier board. But the usb3.0(type-A) cannot work. Only the OTG(microUSB) can work in device mode. My customer carrier board’s usb lane mapping is same as official carrier board. I have no idea now. Could you kindly help me solve this problem ?
