Help Configuring SPI in Device Tree for Jetson Orin NX (16GB)

I have already tested the SPI lookback test it is working. but when I try to check this

Do you mean that the SPI loopback work on your board? (i.e. you can receive what you send)
If so, then it is good for you to work with SPI interface on Orin NX.

@KevinFFF

Check pinmux for SPI if the same as following
$  sudo cat /sys/kernel/debug/tegra_pinctrl_reg | grep -i spi

It is expected since Jetpack 5 does not have that node.
