doggedly 0 Posted September 15, 2021 I was very happy to hear that ASUS took the HDMI cec more seriously than in the first generation, where the cec was only for the S version. But what next? How to control HDMI from a shell? How to read the status with the shell? In the case of other distributions, e.g. ODROID, I met a fantastic solution and it was possible to control HDMI cec signals, for example in this way: echo 0x40 0x04> / sys / class / cec / cmd the above command turned on the screen. Will I get a ready and working solution for Tinkerboard 2? Share this post Link to post Share on other sites
