I have a Sunvell T9 tvbox with rk3328 processor 4/32. I downloaded the image LibreELEC-RK3328.arm-11.0.1-a1.img.gz but won't boot then i replaced the original dtb with armbian's rk3318-box.dtb,now the tvbox has sound and video with no problems. I hope this information can help to someone. Thanks for this excellent tool.
