Yes, I am considering to purchase UDOO x86, however if working on raspi3 why not? why wasting more money which I can spend for other equipment..
Mr Sebastian Kuzminsky just make for jessie i386 not amd64 I've built new RTAI kernel packages for Debian Jessie, using Linux 3.16.7 and RTAI 5.0-test1, and I'm soliciting wider testing. There are no debian packages of LinuxCNC for this new platform yet, but the branch "rtai-5" in our git repo works on it. In order to test it, you need to install Jessie (i386) using the regular debian.org installer, add "debhttp://linuxcnc.org jessie base" to your sources.list, install the linux-image and rtai-modules packages from there, and reboot. Then build the rtai-5 branch of linuxcnc and let it rip. I've moved my CNC Bridgeport with this combination of software and it seems to be working well. -- Sebastian Kuzminsky I am expecting image for rasbian jessie includes rtai and linuxcnc.
