I have agx xavier on hand, it’s official kit,.
run ubuntu 18.04,
kernel version 4.9.140-tegra,
use SDKmanager 4.3.
There is already one /dev/spidev0.0 on system, and I configure with this cmd ‘sudo /opt/nvidia/jetson-io/jetson-io.py’, now the /dev/spidev0.0 working fine.
Now I want add new spidev on system, like /dev/spidev0.1, use chip select signals for control,no relevant information found,what should I do?
