You might try googling for:
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.
