I used vendor-provided am335x-boneblack-4dcape-43t.dts file to generate dtb, you can download compiled blob here. The system running on demo is gpiokeys branch of my git repo: . Patch against -head is here.

If you’re interested only in LCD screen - it’s supported by -head but you’ll need to either add device gpiobacklight to BEAGLEBONE kernel config or enable LCD backlight manually using gpioctl: gpioctl -f /dev/gpioc1 18 1. gpiokeys is somewhat more complex thing and still WIP, there are some pieces missing in HEAD I had to hack around to make them work. And I haven’t started research on touchscreen yet.
