Bit of an update. I'm still stuck in the same issue. I re-flashed my BBB
with the latest image:
bone-debian-9.4-machinekit-armhf-2018-03-25-4gb
And I get the same problem. Either it can't insmod because it lacks
permission, or if I run as root, I get:
Creating machinekit directory
MACHINEKIT - 0.1
Machine configuration directory is
'/usr/share/linuxcnc/examples/sample-configs/pru-examples'
Machine configuration file is 'pru-stepper.ini'
Starting Machinekit...
/usr/libexec/linuxcnc/rtapi_msgd: FATAL - will not run as root
