Hi All,
I’m using a rock compute on a CM3 board and the Ubuntu Server 20.04 image.
but I cannot access the SPI bus ?
When looking in dev directory I see no SPI bus, gpio and i2c is there.
When do I need to do to enable the SPI bus ?
also there is no boot/uEnv.txt file to add any overlays?
Any help would be great!.
