Its a shame, and I'd like to use the board on my CNC router.
I understood some of the reasons for the MachineKit fork, but always
thought it was unfortunate that there had been a fork in the first place.
I really would prefer to use LinuxCNC on the BBB, but would need an
idiot's guide to installation.
I have just managed to buy an 8Gb Pi 4 and had hoped to run LinuxCNC
into my 7i96S for my small CNC lathe.
I would be disappointed if LinuxCNC on the Pi is not currently being
supported.

Apparently not ATM, my rpi4 running buster has not received a uspace
update, just the docs for about 90 days now. And my comments about it
have been ignored. Bullseye never did build, the python in bullseye was
too new. Soo I'm limping along with what I have. I did do a git clone
of the recently announce kernel 6.5-rc4-rt, did an very simple make
menu-config to set as much of the rt stuff as I could find and built it
without any complaints, but have not investigated what it would take to
make it run here. I have other irons in the fire to tend to. The last
time I did that, the non-compressed tarball was about 28 megs. No clue
what it might be with all the changes since:
Linux rpi4.coyote.den 4.19.71-rt24-v7l+ #1 SMP PREEMPT RT Thu Feb 6
07:09:18 EST 2020 armv7l GNU/Linux
3.7 years ago now.
I'm curious. I have one of the original Xylotex boards. The link to
this web site implies there's a newer version along with a link to 4GB
BeagleBone Image for MachineKit which I have read hasn't been
supported for years.

My BBBs (3 of them) are all sitting in a box unused. This includes
things like LCD displays, CAN bus capes etc. I had thought about
adding the BBB with CNC to my Gingery Lathe which currently is
controlled by my Electronic Lead Screw product.
What is the status in general with the BBB and MachineKit or LinuxCNC.
Should I just put my stuff on EBAY?
I ask because I also have a 1GB Pi4 with a MESA 7i92H as a desktop
play toy. I think the 1GB is a bit small for LinuxCNC but so far it
has worked. I'm not sure whether support for LinuxCNC on the PI4 has
also gone by the wayside?
So if someone had a BBB and a cape, installs a version of LinuxCNC
(MachineKit) do they run into what appears to happen often now with
trying to upgrade and unknown web links?

It's a replacement for the sysfs interface for gpio (which hal_pi_gpio
uses, for example).
There is an article about it here:
https://lloydrochester.com/post/hardware/libgpiod-intro-rpi/
I have a working-but-slow demo here:
https://github.com/LinuxCNC/linuxcnc/commit/15138feb4a1a811a7b61a6605
55d78b85bdcf86c
(later commits in that branch are not working at all at the moment)
to use the BBB output from gpioinfo above:
loadrr hal_gpio inputs=P8_25,P8_24 outputs=P8_10,P811
