I tried to connect the tv by cvbs(avout) in android and it output the black screen. Only HDMI output work. How can I configurate the video output to cvbs?
You can read this file to use cvbs : android/device/softwinner/dolphin-common/AWDocument/firmware/H3 sys_config.fex使用配置说明V1.1.pdf
Good morning everyone, I'm new to this forum and recently aquired a nanopi M1, I'm from Venezuela and I hope we all can develop our projects succesfully. I'm interested in use CVBS an linux and android, Can you help me?, I saw the answer with the link but I couldn't open it, Can you give me the exact location of the file please?
Good afternoom, If I'm right, You are talking about the H3 microcontroller datasheet, at the section that talks about video output it refers to a MUX that controls wich output is enabled, I think CVBS is the option 1 (the one that is not enabled by default), so you need to change the configuration file from 0 to 1 in order to activate the CVBS output.
