Hi

I am working on the NX Xavier module. I have been trying to get spi0 to show up in the folder /dev through the device tree. It hasn’t showed up.

A few months back, a colleague of mine mentioned that he had to use jetson-io.py to see the spi device in /dev. He was using your custom image on an NX dev kit module and it wasn’t shown either.

Can you provide guidance on how to get the spi0 to show up in /dev. Why did jetson-io.py have to be used to enable the SPI in /dev.

Thanks
Malcolm
