the same thing...
i burn this image again
https://users.armbian.com/jock/web/rk3318/Armbian_23.08.0-trunk_Rk3318-box_bookworm_edge_6.3.13_minimal.img.xz
then after updates (apt update && apt full-upgrade -y)
i found that there is no file rk3318-box.dtb in the /boot/dtb/rockchip folder
i copied rk3318-box.dtb to this location https://drive.google.com/drive/folders/1cXGTblufMjlu-I2aH3hPjgUcU3DzfVQt?usp=sharing
I just copied rk3318-box.dtb from original image (after fresh install), then after update before reboot copied it to boot folder, don't know if it's right or not...
hardware: H96 Max RK3318_V1.4
