Schooner, That was running an image from Robert C Nelson to test out the fixes in a new kernel. I have an image that has been running OK except for horrendous boot times. I updated the kernel with 4.19.19-bone-rt-r21 and now I get this: machinekit@beaglebone:~$ machinekit MACHINEKIT - 0.1 Machine configuration directory is '/home/machinekit/machinekit/configs/ARM.BeagleBone.Xylotex' Machine configuration file is 'Xylotex.ini' Starting Machinekit... Warning - /usr/libexec/linuxcnc/rtapi_app_posix not setuid 'sudo make setuid' missing? rtapi_msgd command: /usr/libexec/linuxcnc/rtapi_msgd --instance=0 --rtmsglevel=1 --usrmsglevel=1 --halsize=524288 rtapi_app command: /usr/libexec/linuxcnc/rtapi_app_posix --instance=0 /usr/bin/realtime: line 237: /usr/libexec/linuxcnc/rtapi_app_posix: No such file or directory rtapi_app startup failed; aborting halcmd: cant connect to rtapi_app: -1 (uri= uuid=a42c8c6b-4025-4f83-ba28-dad21114744a): rtapi_rpc(): reply timeout
So can you tell did I choose the wrong kernel??? I used this from elinux: 4.19.x All BeagleBone Variants + RT sudo /opt/scripts/tools/update_kernel.sh --bone-rt-kernel --lts-4_19 Alan > On Feb 12, 2019, at 11:11 PM, [email protected] wrote: > > Check what is installed. > > The error re not setuuid is misleading, the main question is why are you > trying to use rtapi_app_posix, it should be rt-preempt > On 2/13/2019 12:19 AM, Condit Alan wrote: >> Robert, >> >> I tried updating the kernel first on my other image, but when I tried to >> start machinekit I got a message unable to setuid need sudo makesetuid.
