Hi Jalodi, Take a look at: https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-BONE-REPLICAP-00B1.dts Which is the only current 4.1.x/pru user.. make sure you boot with: dtb=am335x-boneblack-overlay.dtb To get the pru pins.. btw, Elias has a good image here: http://wiki.thing-printer.com/index.php?title=Kamikaze Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
