Today all images boot with cape-univeral enabled, so if your overlay needs specific pins, you need to tell it to disable them.. Or jsut disable: enable_uboot_cape_universal=1 in /boot/uEnv.txt If that still doesn't fix your problem, please run this script and report it's output so we can help debug.. sudo /opt/scripts/tools/version.sh 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.
