You might try googling for:
linux-image-rpi2-rt_4.4.4-rt9-v7+-7_armhf.deb
Which will at least give you a kernel that will run it.
pin it. I can send that too.
The install is armbian jessie lite. Downloadable from the armbian site
LinuxCNC is the uspace version of 2.8-pre. Weird config, no PID's used
Works fine.
PM me, and I can send you what should be working configs IF you've
installed and wired up a pair of MPJA's 100 ppr a/b encoders to function
as hand wheels. This encoder is also available elsewhere, s/b under $25
a copy. Interface is a mesa 7i90HD, with 3 7i42TA's to protect the 3.3
volt 7i90HD from the noises. Spindle control is a 240 volt single ph
input 1.5 hp vfd, running an old (probably about 40 yo) 3 ph, 1 horse I
took off a scrapped air compressor.
But no use further cluttering this list, so PM me.

I've got jessie on an r-pi3b, and they call it an armhf. Running
xfce. Color depth could be better, 5,6,5 framebuffer IIRC, makes
about 7 frames a second, but would also be even slower. Just barely
fast enough to run LinuxCNC.
Could you give me a hint where to download a working image? I'm
struggling with RPi+LinuxCNC for ages, almost gave up that project.
