If you don't actually have a BeBoPr board, you're starting with about the worst example configuration you could choose. The BeBoPr was designed for the original BeagleBone (White) and uses a device tree overlay that conflicts with the eMMC and HDMI pins (as you've found). I'd recommend starting with a more current configuration targeting the BeagleBone Black that uses the universal overlay (which is easier to modify than having to craft your own custom device tree overlay). Try loading the CRAMPS example configuration. It will work fine even if you don't have an actual CRAMPS board, you will just have to either wire a normally-closed ESTOP switch between P8.26 and P8.17, or modify the HAL file to bypass the external switch: https://github.com/machinekit/machinekit/blob/master/configs/ARM/BeagleBone/CRAMPS/CRAMPS.hal#L224 There are already two PWM outputs configured, and you can add more if you need. -- Charles Steinkuehler [email protected] -- 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.
