Dear all, I have another issue which results in joint 0 following errors. My hypothesis is that the PRU is not running as hal-meter shows position-cmd being input to the hpg.stepgen but position-fb stays unchanged. The cape was detected during boot. I have sucessfully used GPIO pins but the PRU does not seem to work.
I have observed the same problem using v4.14 with Preempt RT on Strech and with v3.8 xenomai on Jessie. Now I'm running out of ideas what to check and try :-( Pastebins of the ini, hal and bbio files as well as the logs are located as pastbin links below hoping that some wise guy can help me resolving this. BTW: Having worked with Linux as user for some time but being fresh to ARM Boards and the BBB I have been taking notes of my endeavor getting this to work. While I value that everything is written down somewhere I feel that improved documentation (howto) would attract more users to machinekit. I would sign up for cleaning this up and putting this somewhere if you think such a writeup is helpful. My scribbles are here: https://pastebin.com/WFKXMsx9 I would plan to add u-boot overlays and cover the hardware side of things since I'm using a prototype cape + few optocoupler modules + 3.3 -> 5V level shifters to build a machinekit hardware cape BR and thanks and happy new year, Malte Shell output of: export DEBUG=5; machinekit interkrenn.ini https://pastebin.com/wgxE8eD2 Relevant part of /var/log/linuxcnc.log https://pastebin.com/GyWM6muP My ini file (not simplified i.e. there are axes defined in there that are not mapped in the hal files) https://pastebin.com/jRvjfmRw My Hal file (simplified/stipped version which shows the issue): https://pastebin.com/txFHiNar My bbio file (simplified/stipped version which shows the issue): https://pastebin.com/zA4dyCg2 machinekit@beaglebone:~/mk_ik/config$ uname -a Linux beaglebone 4.14.79-ti-rt-r84 #1 SMP PREEMPT RT Tue Nov 13 20:33:45 UTC 2018 armv7l GNU/Linux machinekit@beaglebone:~/mk_ik/config$ cat /proc/cmdline console=ttyO0,115200n8 bone_capemgr.uboot_capemgr_enabled=1 root=UUID=94daacb3-de67-41a5-8087-c68a02c7e893 ro rootfstype=ext4 rootwait uboot_detected_capes=cape-universal, coherent_pool=1M net.ifnames=0 quiet -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
