I thought I'd test the latest LE for my Rockchip box (LibreELEC-RK3328.arm-9.80-nightly-20200107-eda06b1-box.img.gz), but the image doesn't contain .dtb nor extlinux file (only system and kernel files). Without it, the system won't even boot. It was the same case with the earlier image I tried out from a few days ago.
Why is that? What am I doing wrong?
