Runs on raspian. here is /etc/issue Raspbian GNU/Linux 8 \n \l > ...but with Jessie you could maybe run multiarch and get the official > armhf libraries running alongside the Raspbian ones? > No clue. Until an update over this past weekend, it just ran, but much of the /boot partition was updated, and now it will not boot at all. So I'm running on a re-install of raspi3-linuxcnc-hm2-rpspi-8GB.img Which I got from one of the developers as a .gz. I can make it available on my web page, but its 6Gb and small change so the transfer will take a while. Done, its in the opt/lathe-stf subdir of my web page. Put this image on a 16 or 32Gb u-sd card, then put the card in the pi and power it up. If it doesn't run raspi-config on bootup, open an LXterminal, and sudo raspi-config one of the first options is to expand the filesystems 2nd partition to take advantage of the whole card, choose that and have it do it. I also, while the LXTerminal is handy, change user pi's passwd to match yours so you don't have yet another password to remember. Then, because synaptic, when you install it, is locked down to root, and a sudo doesn't work, do a sudo passwd and set yourself a big long root password, but one you can remember. And just in case your wet ram is as old as mine, put a dymo label next to the pi with it on it. If the video doesn't fit the screen: sudo nano /boot/config.txt find the framebuffer size options and comment them out, hit ctl+o,return then ctl+x to exit nano. reboot for effect. EDID does work, but you might have to ascertain the monitors h & v size, go back into /boot/config.txt, uncomment those 2 framebuffer size lines and enter the proper sizes for your monitor. I am using HDMI cabling straight thru, but its my impression some hdmi->vga adapters will garble that EDID feedback. > >> I don't want to point him > >> this direction if it's not particularly stable, but he's > >> technically savvy enough to get over a few rough spots. > > > > Since I'm walking on new ground with this, Martinjack seems to have > > disappeared, its a somewhat lonely trail.
