USB port is not working after successfully flashing the Jetson module with Custom Carrier board

Hi Nvidia,

I am using Jetpack version 6.1 L4T r36.4.3.
We are using Jetson 64Gb Industrial module with Custom Carrier Board. There we are using USB type A port for Flashing the Module as well as general purpose USB.
After successful flashing of module the USB port is not working at all even after restart.

We have only 1 USB in our schematics which is Type A.

here is the serial log from debug port-

any help will be appreciated.

Thanks,

You need to update the device tree for USB part.

Refer to below document:

Jetson AGX Orin Platform Adaptation and Bring-Up — NVIDIA Jetson Linux...

Hi WayneWWW,
thanks for the suggestion on this issue. We followed this and able to get the USB port up and working.
One minor concern is that we aren’t sure if the USB3.x interface signals are active or not. The USB test tool is not giving reliable results.
We have one observation as below in the device tree -
devicetree.zip (38.4 KB)

I am not sure about the below line what it does in USB3-
nvidia,usb2-companion = <0>;

thank you,

usb3 port cannot have just usbSS lane. You have to have usb2 data lane coming out with the SOM directly.

In your block diagram, that is usb2-0, so give 0 to nvidia,usb2-companion
