Hi everyone, I am trying to get MachineKit running on a Snickerdoodle Black dev board from Krtkl. My goal is to eventually get mksocfpga running and build a 3D printer controlled remotely via MachineFace.
I managed to compile MachineKit from source, and am trying to start it using the 5i25-zynq configuration (I don't actually have a bitstream to program the FPGA yet, just trying to get MK running). Starting from the command line, MachineKit errors out because the rtapi app gets terminated due to "stack smashing". Output to from the terminal is as follows: MACHINEKIT - 0.1 Machine configuration directory is '/home/snickerdoodle/machinekit/./configs/hm2-soc-stepper' Machine configuration file is '5i25-zynq.ini' Starting Machinekit... *** stack smashing detected ***: rtapi:0 terminated halcmd: cant connect to rtapi_app: -1 (uri= uuid=a42c8c6b-4025-4f83-ba28-dad21114744a): rtapi_rpc(): reply timeout E: 17-10-20 11:16:04 dangling 'DEALER' socket created at hal/utils/halcmd_rtapiapp.cc:281 io started halcmd: cant connect to rtapi_app: -1 (uri= uuid=a42c8c6b-4025-4f83-ba28-dad21114744a): rtapi_rpc(): reply timeout halcmd: the rtapi:0 RT demon is not running - please investigate /var/log/linuxcnc.log E: 17-10-20 11:16:11 dangling 'DEALER' socket created at hal/utils/halcmd_rtapiapp.cc:281 halcmd loadusr io started halcmd: cant connect to rtapi_app: -1 (uri= uuid=a42c8c6b-4025-4f83-ba28-dad21114744a): rtapi_rpc(): reply timeout The lines starting with "halcmd:" are repeated until MK finally cleans everything up and quits. Operating system is Ubuntu 16.04, running an rt_preempt kernel that I compiled from source. Running "uname -a" gives "Linux snickerdoodle 4.9.0-rt1-snickerdoodle-68568-gfc719c0-dirty #1 SMP Tue Oct 10 19:54:36 MDT 2017 armv7l armv7l armv7l GNU/Linux".

Git log shows: commit 15d5a3f6b1ac1760d3ec68c853b5c1e2e0101533 Merge: d88049e def2443 Author: Bas de Bruijn Date: Fri Oct 13 09:53:46 2017 +0200 Interestingly, I have to "export FLAVOR=rt-preempt" in the shell before attempting to start machinekit, or else it tries to load rtapi_app_posix, which I did not compile. If anyone can point me towards a solution and help me get MachineKit running, I would be very grateful.
