I have been playing with RPI for some time now trying to get Hal2Arduino
working for a multi-task hobby cnc that I have built. Have software working for
xyza axis still need to hook up drivers and steppers. I know that linuxcnc is
not going to work as well as what Gene Haskett is doing but this is a hobby
machine. Still having trouble getting xyuv axis part of machine working have a
config file error to figure out.
But the reason why I responded to this post I have instructions on how
to create a minimal install for RPI image that will work on RPI2 or 3. Seems it
could help allot of people, so here it is.
Follow these direction in order to make a minamal Raspbian "Debian Jessie"
install
with a realtime kernel,(ver. 4.4.9-rt17) and Mate Desktop and Linuxcnc
sdcard will work with rpi2 or 3
Download Emlid image for sd card then extract from
https://files.emlid.com/images/emlid-raspbian-20160718.img.xz
# On Linux computer download Etcher to write image to sdcard at
https://etcher.io/
Download, extract and run Etcher
Select the archive file with image and sd card drive letter.
Click “Flash!”. The process may take a few minutes.

# RT-PREEMPT realtime kernel

# Extract files

So does the armhf build run in Raspian or are you using qemu or
something? AFAIK, standard Debian armhf code won't run on the RPi
because Raspbian uses a different ABI (due to the not-quite full
armhf compatible CPU on the original RPi).
It might be worth considering that Gene's experience seems to be
that LinuxCNC on the Pi runs less than flawlessly.
Indeed. I've only just started playing with the RPi3 and have already
hit some issues. I was hoping the GPU would be usable, but it looks
like there are still problems. I think the BBB (or an SoC+FPGA) is
probably a better choice if you don't need a native GUI, and if you
_do_ want a GUI a low-end x86 box is likely a much better choice.
I've ordered one of these x86 SBCs to play with and see if I can get
it talking to Mesa hardware via SPI:
http://up-shop.org/up-boards/2-up-board-2gb-16-gb-emmc-memory.html
...if it works out, it may be a good midway point between the ARM
based SBCs and a full x86 machine.
https://wiki.debian.org/RaspberryPi
Seems to suggest that armhf works on Pi >= 2.0
buildbot "sim" builds run with realtime on preempt-rt kernels.
Yeah, I should be able to use the armhf builds if I'm running stock
Debian (which works on the RPi 2 & 3). I started with Raspbian to see
what the "out-of-the-box" experience is like, and figure it's unlikely
I can tweak Debian to work better than Raspbian. I'm unclear what
Gene's running, but I'm guessing it's Debian armhf rather than
Raspbian.
Nope, raspian. From my /etc/apt/sources.list:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib
non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://archive.raspbian.org/raspbian/ jessie main contrib
non-free rpi
deb http://buildbot.linuxcnc.org/ jessie master-sim
deb-src http://buildbot.linuxcnc.org/ jessie master-sim
no debian in site other than whats been thru the raspian "filter".
