SPI Ports
SPI device nodes in Linux can be identified as follows:
$ ls /sys/bus/acpi/devices/8086228E\:01/physical_node/spi_master/spi2/
device power spi-SPT0001:01 statistics subsystem uevent
Installing ACPI overrides to enable SPI in userspace
By default, no SPI device is created for user access by default. To enable access to SPI from userspace you should add an ACPI override on the kernel
- Download this tar.gz file and uncompress it.
- Enter in the extracted directory and type in a terminal:
$ sudo ./install_hooks && sudo acpi-add spidev*
- Reboot the system
Now you should see the SPI devices under /dev
$ ls /dev/spi*
/dev/spidev2.0
