Hi MX_Master,
So I've got linuxcnc up and running on my orange pi (installer script works extremely well, thank you for all your work on that) - I haven't actually connected it to driver/motors quite yet, but I ran the latency test and note that jitter/latency is still quite high.
Is this something I should be concerned about, or does the jitter/normal latency not matter so much given that stepgen can now run on the separate RISC core (ie: not shared with the main CPU/kernel)?

Latency values for these boards are all about 50-100 us. Old kernel and OS versions has a bit better values. But when we using a separated CPU core, these latency values can be ignored.

This is amazing news. I'm going to try things out properly with actual hardware very soon.
Is it just me, or does this make the orangepi's (or rather, the Allwinner H3/5/6 CPUs) kind of the ultimate platform in terms of cost vs performance for linuxcnc/machinekit?
I feel like this should be getting more attention

Enable the "partner" and "source code" repositories in the software sources, do an update and try to install again.

Try Armbian Buster and make
before project installation.
apt update & apt upgrade
before project installation.
