What is the difference between kenel overlay (device tree) and u-boot overlay? Are they the same thing?
I have succeeded with u-boot overlay. How do I get the kernel overlay (dtb_overlay) to load successfully? I add my uEnv.txt for loading kernel overlay(dtb_overlay). 2020년 9월 14일 (월) 오후 6:26, 어지수 <[email protected]>님이 작성: > I send uEnv.txt to you. > I success but i have a question > > Are uboot_overlay and dtb_overlay the same? > > > 2020년 9월 14일 (월) 오후 6:16, 어지수 <[email protected]>님이 작성: > >> I have some questions. >> Are dtb_overlay and uboot_overlay_addr4 the same thing? >> Are uboot_overlay and dtb_overlay the same? >> >> thank you for a lot help >> regards >> jisu >> >> 2020년 9월 12일 (토) 오전 3:15, Robert Nelson <[email protected]>님이 작성: >> >>> On Fri, Sep 11, 2020 at 12:30 PM debian <[email protected]> wrote: >>> > >>> > Could i use overlay (Device Tree) in BeagleBone AI? >>> > Could i know how to use overlay (DT) in BeagleBone AI? >>> > >>> > First, I dont know to modify uEnv.txt ? >>> > I don't know what to edit in uEnv.txt. >>> > >>> > Can I know which part I need to fix? >>> >>> Either start with this image (unless you need xorg) >>> >>> >>> https://rcn-ee.net/rootfs/bb.org/testing/2020-09-07/buster-iot/am57xx-debian-10.5-iot-armhf-2020-09-07-4gb.img.xz >>> >>> Here is the list of overlays: >>> >>> >>> https://github.com/beagleboard/BeagleBoard-DeviceTrees/tree/v4.19.x-ti-overlays/src/arm/overlays >>> >>> Regards, >>> -- >>> Robert Nelson >>> https://rcn-ee.com/ >>> >>> -- >>> For more options, visit http://beagleboard.org/discuss >>> --- >>> You received this message because you are subscribed to a topic in the >>> Google Groups "BeagleBoard" group. >>> To unsubscribe from this topic, visit >>> https://groups.google.com/d/topic/beagleboard/-7xASl-oqic/unsubscribe. >>> To unsubscribe from this group and all its topics, send an email to >>> [email protected]. >>> To view this discussion on the web visit >>> https://groups.google.com/d/msgid/beagleboard/CAOCHtYi9NwNJNOQbkZLCJk_-LApGN-VRTVPQuuzTtuTX10sNew%40mail.gmail.com >>> . >>> >> -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
