Help me out with some talking points! :)

[1] So you want to make your own image files? Grab my modified
version of Robert C Nelson's build scripts from github:
https://github.com/cdsteinkuehler/omap-image-builder
Make sure
for hardware motion control, but it probably wouldn't take
much to turn the PRU into an EPP controller and talk to something like
a 7I43 using hostmot2. Hmm

Now you just have to setup LinuxCNC and run it. Make sure you
have X11 forwarding enabled, or have set the DISPLAY variable to
point to an open X server
LinuxCNC in a good light.
...and thanks for the link to the manuals! I've been crawling through
the integrator and HAL docs, but I somehow forgot about the users guide!

as usual, writes are cheap and reads are expensive.
Note the latency issues disappear if you're using PRU direct inputs,
but that restricts the I/O allocations quite a bit.

This appears to only work under Precise+ (no u-boot for Lucid, it

a formal

don't have a good feel for the project history or personalities
involved.

I particularly like the acceleration control in LinuxCNC. It
seems smoother than the Arduino code.
