There is no "pruss driver", the UIO driver used to talk to the PRU is part of the kernel source. The prussdrv library used to facilitate controlling the PRU was written by TI, and I think I initially got it from github somewhwere (likely in the old BeagleBone PRU support files repo). The version I use has been pulled into the Machinekit source tree, see the files with "prussdrv" in the name: https://github.com/machinekit/machinekit/tree/master/src/hal/support/pru -- Charles Steinkuehler char...@steinkuehler.net -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
