deb http://buildbot.linuxcnc.org/ jessie master-sim Working quite well and as stable as a block of granite these days. With a pinned rt-preempt kernel, the rest of it is kept uptodate from the armbian repo's a couple times a week, and I've not experienced the local event throwaway in 2 or 3 months. Maybe one of the updates has fixed it? However arm64 has not been added to the buildbot to my knowledge as Sebastian has not found an affordable arm64 industrial rated board to add to the buildbot farm, as of maybe 6 weeks ago when I last asked. > deb http://buildbot.linuxcnc.org/ jessie scratch-rtpreempt > deb-src http://buildbot.linuxcnc.org/ jessie scratch-rtpreempt > Umm, thats new. Is it 2.7 something or master based? I don't have a 2.7.build on any of my machines, master seems more stable. > > arm build only exist in wheezy and jessie > there are no arm anything files in newer or older builds > i think I can edit this webpage > but the maintainers ought to know it just doesnt exist > Right, no arm64 yet. That I know of, so I've figured on building it myself if the pi dies. But the gpio setup on the rock64 is different, and the spi driver (rpspi.ko) is conditionally built to run ONLY on a pi3b, so thats the first thing that has to be fixed as it runs 40x faster that any linux spi driver. So there are several roadblocks before a rock64 will actually move a machine, and that driver is the biggest one. That I suspect will take a coder well above my pay grade to fix. There is a bit of code about that can simulate a parport on the rock64's gpio, which can in turn drive the 7i90 interface, but no clue if its fast enough to compete with the faster (it writes 32 bit packets to the 7i90 at 41 megabaud, reads 32 bit packet responses at 25 megabaud) this driver can do on the pi. Thanks and take care, TomP. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
