Thank you. R2S has a built in eMMC and USB. The only way to get a new image is to boot from USB but it seems like I have to manually load the image in u-boot. Is the u-boot script (boot.txt) for the build somewhere in GitHub?

Have you tried all of the gxm dtb files? Per the instructions (https://forum.armbian.com/topic/33676-installation-instructions-for-tv-boxes-with-amlogic-cpus)

@maxsub I was not even aware, that boot from USB is a thing. The RV2 boots from SD via extlinux, here is the relevant uboot output.

i am trying to install armbian on a vorke z6 plus s912 amlogic box. As there is no S912 dtb, i tried using /dtb/amlogic/meson-gxm-t95z-plus.dtb with this iamge: Armbian_26.02.0_amlogic_s912-t95z-plus_trixie_6.18.15_server_2026.03.01.img.gz renamed u-boot-s905x-s912.bin to u-boot.ext After inserting and pressing the reset button, before applying power, i get into the recovery menu What dtb file or image can i use to get armbian running?

Depends on the image you are using. The image for 3 LTS should work for the 3 LTS. The image for the 3 (without lts) will not.
