Hi @balbes150 Thank you for the great work you are doing. I could not make my device work with any of the dtb provided in the dtb directory. Interestingly my system booted without any dtb file. Both Debian stretch server and Ubuntu Xenial (Mate desktop) works without any dtb file. However, without dtb file it only shows 815MB ram (no wifi, no bluetooth). And provided sample video file plays slowly when full screen turned on. My Device: OTT M8S (Amlogic s812), 2GB RAM, 8GB ROM, BCM 4335 wifi. The version in the PCB written as: M8 V8_9 (20151031) Here are the UART output: original_android_fw_boot.txt without_dtb_ubuntu_mate.txt With DTB file: meson8m2_n200C_1G.txt meson8m2_n200C_2G.txt meson8m2_n200C_2G_LAN100.1.txt meson8m2_n200_2G.txt How can I activate 2 GB Ram enable Wifi (bluetooth not important) Improve HDMI performance (not important but highly interested ) Thanks in advance
