I have an Nvidia ORIN AGX developer kit and I am unable to access the SPI interface. I am running Ubuntu 20.04 and I have updated the Jetpack version to 5.0.2-b231. I have run the jetson-io.py utility and enabled the spi pins. My python program crashes trying to access the SPI bus device (…" can’t open file…"). I noticed that /dev directory does not list spidev*. I think this is the source of my problem. Why is spidev* not listed in the /dev directory? I need help on how to install/enable the SPI bus. Suggestions? What am I missing? THANKS!
You need to load the spidev driver by below command first.
sudo modprobe spidev
