For enabling SPI support for Jetson Nano please use this patch. This path cover all Jetson nano boards (eMMC and SDcard only).
SPI devices after adding patch are available on /dev/spidev0.0 and /dev/spidev0.1 (as generic spidev devices). You can use spidev_tet tool and shortcut MOSI/MISO pins to test if communication is working as expected.
Note: some extension boards with SPI chips maybe will not work due to the level shifters which are assembled on 40 pin header. For more info look at: 40 pin header considerations
