Enabling SPI on Jetson Nano 2GB

I have used Jetson IO to configure the 40 pin header in the Nano 2GB for SPI1 (LT: 32.4.4).
I was wondering if there are any SPI libraries that are provided that can be used to test the connection, modify word length, speed, etc.? I noticed that spidev is not in the native SD card image.

Thanks!

For the dev spi node you need to enable it by the jetson-io.
Also you can search the SPI relative topic to get more information.
