That would be expected... It shares pins are already muxed with the hdmi output.. So use one of the dtb= overrides in /boot/uEnv.txt dtb=am335x-boneblack-emmc-overlay.dtb or dtb=am335x-boneblack-overlay.dtb BBB compatibility issues: https://github.com/beagleboard/bb.org-overlays/blob/master/readme.md 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.
