TX2-NX has no spi node under /etc directory

I’m working on one design which changing NX to TX2-NX. with NX the SPI interface works fine, but with TX2-NX, I cannot see spi node (like spidev0.0, spidev0.1 etc) under /etc directory. I checked the dts file is normal, and when I configure the 40 pin header by jetson-io.py, it works and spi signal can be shown. any hints are appreciated. thanks in advance.

Need loader spidev driver by below command.
Also the spidev*.* should be at /dev instead of /etc

sudo modprobe spidev

Thanks, it works, yes that was a tpyo, /dev is the right dir name.
