This isn't an issue anymore.. Make sure your *.dtbo is under /lib/firmware then run: sudo update-initramfs -uk `uname -r` to make sure the *.dtbo get's copied to the intrd. (it'll still read it from the /lib/firmware) otherwise, dmesg | grep cape 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.
