The BeagleBone is currently using software step/dir, generated by the PRU and running with a 10 uS update rate that I hope to reduce to 1 uS or less when I get to tweaking for speed. There's currently no PCI or PCIe slot to hook a Mesa card to the BeagleBone 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.
