OK here are the test results: machinekit@beaglebone:~$ cat /sys/kernel/realtime 1 machinekit@beaglebone:~$ cat /boot/config-4.19.23-bone-rt-r23 | grep CONFIG_PREEMPT_RT_FULL=y CONFIG_PREEMPT_RT_FULL=y machinekit@beaglebone:~$ uname -a Linux beaglebone 4.19.23-bone-rt-r23 #1stretch PREEMPT RT Tue Feb 19 17:12:46 UTC 2019 armv7l GNU/Linux machinekit@beaglebone:~$
I am getting some errors on the Axis screen but I am running inside without a controller attached. However, that said, it boots with no problem and starts machinekit. So I guess the next step is to take the BBB back out to the shop and try running the machine! Schooner, you said rtapi.c tests for cat /boot/config-4.19.23-bone-rt-r23 | grep CONFIG_PREEMPT_RT_FULL=yes but that test failed, I looked at the config and saw that CONFIG_PREEMPT_RT_FULL was set to “y” not “yes”. Did you really mean “yes” or is “y” OK?
