Unlike 3.8 where the eMMC/HDMI where separate *.dtbo's, we haven't seperated them out 'yet' in 4.1.x... For right now, use the custom dtb file: am335x-boneblack-overlay.dtb (this has hdmi/eMMC disabled) 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.
