Ethernet disabled by default on the Orin NX?

Just making sure that I’m not missing anything, but the Orin NX devkit + L4T seems to come with the ethernet disabled?

In platform/t23x/common/kernel-dts/t234-common-cvm/tegra234-cvm-p3767.dtsi

   ethernet@6810000 {    
       status = "disabled";

And none of my ethernet devices are enabled in the default device tree:

p2-orin:/proc/device-tree$ cat eth*/status

Should I just flip that to “okay” or is there a different device tree I should be using? I’m using the p3509 devkit


ethernet@6810000 is for 10GbE network which is not supported on Orin NX so of course it is set to disabled.

What is your method to flash p3509 devkit? My etherent is fine with this setup.

I flashed it with L4T using the initrd method described in the docs. Copy pasted the commands as-is

sudo ./tools/kernel_flash/ --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p \
"-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nx-devkit-16gb internal

There is no ethernet device under /proc/device-tree that has status = “okay”

Could you let me know which Ethernet device should be the one that is enabled so I can find it in the device tree files?



No, you don’t need to do anything with device tree because your flash command is wrong.
jetson-orin-nx-devkit-16gb is not for your setup.

Please use p3509-a02+p3767-0000.conf instead.
