Did you actually try /dev/spidev*? ps, you really should upgrade from: 4.1.38-bone-rt-r24 -> 4.4.x-bone-rt-ry As there was a lot of fixes in 4.4.x Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
