Thank you for your interest! As you said, I tried other DTB files. meson8b-odroidc1.dtb The display is finally ON! But the network is dead. meson8b-mxq.dtb The display output is still dead. But the network works, so I can access SSH. So I changed DTB to DTS and tried to fix it. But there's an error message like the picture below. Can you give me some advice? There is an error even if I don't fix the file and just do a two-way conversion. DTB -> DTS -> DTB

Does anyone know this board? I bought it from TAOBAO in China. It has S805 CPU. SD Card Write Armbian_21.02.0-trunk_Aml-s812_bullseye_current_5.10.0_.img and meson8b-mxq.dtb, the network works, but the screen does not appear. (At Armbian_5.67_Aml-s805_Debian_stretch_default_3.10.108_desktop_20181207.img & meson8b-mxq.dtb, Display screen on.) Someone helps the screen appear on Debian Bullseye. Or I'd appreciate it if you could help me install the Retropie & Lakka.
