While it worked great for many years, just too many device-tree api changes over the years.. Our 5.10.x-ti branch has direct support for the BB-BONE-4D4C-01-00A1.dts: https://git.beagleboard.org/beagleboard/linux/-/blob/5.10/arch/arm/boot/dts/overlays/BB-BONE-4D4C-01-00A1.dts , thus it's already built for this lcd. The other trick, the Black defaults to built-in hdmi.. Another board has shipped that's the Black without an HDMI. "BeagleBone-Green", so in u-boot force fdtfile=am335x-bonegreen.dtb and apply the BB-BONE-4D4C-01-00A1.dtbo overlay.. Regards, -- Robert Nelson https://rcn-ee.com/
