Hello All,
Currently I am having issues with the USB controller inside the device tree table for the AGX 64 GB Development Module not working. I was trying to migrate a USB device tree table I had functioning for L4T 35.4.1 to the L4T 36.3 but I can’t seem to get it to function correctly. I have been following the guide here with no luck: Jetson AGX Orin Platform Adaptation and Bring-Up — Jetson Linux Developer Guide documentation.
I am using a custom carrier board which has a single micro usb type b connector port instead of a usb type c port (J40 on NVIDIA carrier card dev kit)(Pins F12 and F13 on the AGX Module). When I boot up the module I can see that the usb port does work correctly during the UEFI splash screen and I can use the esc key to get into the settings with no problems which makes me feel that the hardware configuration is correct. It’s when the UEFI shell closes and enters the normal boot cycle (kernel boot up) I can see the the USB port turns off and won’t come back on.
This is the serial log I see when I connect to the debug serial port during a cold boot:
serial_log_L4T_36_3.txt (71.8 KB)
This is the dmesg:
dmesg_log_L4T_36_3.txt (54.7 KB)
This is the device tree file I have been modifying under the “/hardware/nvidia/t23x/nv-public” directory.

When I check the device tree table from the serial port I see the following:
root@ubuntu:/proc/device-tree/bus@0/i2c@c240000/ucsi_ccg@8/connector@0# cat data-role
host
root@ubuntu:/proc/device-tree/bus@0/i2c@c240000/ucsi_ccg@8/connector@0# cat label
USB-A
root@ubuntu:/proc/device-tree/bus@0/i2c@c240000/ucsi_ccg@8/connector@0# cat type
micro
If anyone could please help guide me on how to properly configure the ‘usb2-0’ port to be a host device that is a type A connection I would be highly appreciative!
