Usb3.0 port of Jetson orin nano devkit

I used Jetpack6.0DP. I was going to enable Orin nano’s USBSS2, but after flashing to the board, the device tree did not update and USB3.0 did not work properly.
Modify the file directory is:
Linux_for_Tegra/source/hardware/nvidia/t23x/nv - public/tegra234 - p3768-0000. dtsi
tegra234-p3768-0000.txt (4.8 KB)

The generated file directory is:
boot/tegra234-p3768-0000+p3767-0000.dtb
tegra234-p3768-0000+p3767-0000.txt (163.9 KB)

The following two files are modification files, and the generated files are converted to dts files

Was your bring up fine on jetpack5?

I don’t suggest to bring up custom board on jetpack6 as this is developer preview. The document is also not ready for this part either.

I switched back to jetpack5. But the generated file usb3-2 does not have phandle.Is there any problem with this?

You should clarify how you generate your file out.

Hi,What I do with this part of the file is compile and transfer it to the destination folder.
./nvbuild.sh -o $PWD/kernel_out
and
sudo cp -rf kernel_out/arch/arm64/boot/dts/nvidia/* /home/microtnt/nvidia/Linux_for_Tegra/kernel/dtb/

So dose that phandle exist in the dtb under kernel_out or not?

Hi, as shown in my picture above, there is no phandle.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Is this still an issue to support? Any result can be shared?
