I tried to enable SPI in Userspace using the procedure described on the site with the following results:
danny@danny-ODYSSEY-X86J4105:~/Downloads/spi-enable$ sudo acpi-add spidev* -- generating spidev1.0.asl -- generating spidev1.1.asl Added 2 asl files Update initramfs... update-initramfs: Generating /boot/initrd.img-5.4.0-40-generic I: The initramfs will attempt to resume from /dev/nvme0n1p2 I: (UUID=cf460e99-6a0f-431f-9e96-dfd2943a1bfd) I: Set the RESUME variable to override this. update-initramfs: Generating /boot/initrd.img-5.4.0-26-generic I: The initramfs will attempt to resume from /dev/nvme0n1p2 I: (UUID=cf460e99-6a0f-431f-9e96-dfd2943a1bfd) I: Set the RESUME variable to override this. Done danny@danny-ODYSSEY-X86J4105:~/Downloads/spi-enable$ sudo ls /dev/spi* ls: cannot access '/dev/spi*': **No such file or directory**
Apparently the SPI devices are not created in the /dev directory. Any advice how to proceed?
