Hi,

I works on the demoboard of sabreLite of Element14. I have made a software to play some video on hdmi with gstreamer. After the system has boot (on linux 3.0 with busy box), my software send audio and video signal through HDMI and it works fine. But after about 8 minutes, there no more signal on the hdmi, I can always use the console through UART and my software still run. When I try to restart an avi file with an audio channel, it tell me that "asoc: can't open platform imx-hdmi-soc-audio.0".

It seems that after 8 minutes the system put HDMI in sleep mode, how can I avoid that ?

Hi,

You can try consoleblank=0 in your bootargs. That should keep the display from "going to sleep".

I had the same issue initially, after applying that it never blanks.
