Just a couple points.. I don't use Android on these devices, thus i don't support it.. (My Free time, is My free time. ;) ) The 4.1.x-ti kernel used by: http://www.2net.co.uk/android4beagle.html was really just a preview release. All the refinement and u-boot overlay enhancements were done on the: v4.4.x/v4.9.x/v4.14.x releases. So feel free to swap out the 4.1.x-ti with either 4.4.x-ti or 4.14.x-ti.. With the move to u-boot overlays: the version of u-boot became VERY important, the bootrom loads u-boot from the eMMC first.. So yeah, if the version of u-boot doesn't support overlays is installed to eMMC you have to nuke it. ;) 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.
