Zedboard No HDMI Output after 10 minutes

Hello!
I am working on a project with zedboard . I need to output images to the monitor via HDMI interface . I download a demo zedboard-oob-design from official website and run linux on zedboard successfully.The images can be output via hdmi successfully,but it can only work for about 12 minutes.There will be no HDMI output after 12 minutes,but I can still control OLED and LEDs on the terminal.I need the board keep displaying images via hdmi for at least 30 minutes.I don't know how to work around it . I really need your help!Thanks a lot!

Regards,
Xiao Yuan

The ZedBoard OOB Linux image is supplied by Digilent so you would need to contact them to find out why the HDMI interface turns off after 10 minutes, but I did verify that it does. I checked with the reference design suggested by Bryan above and the HDMI display does not time out after 10 minutes, so the timeout is related to the Digilent Linux implementation.

You might also want to consider using another Linux implementation for the ZedBoard. There are both Linux and HDMI reference designs posted here: http://zedboard.org/support/design/1521/11

You might also want to take a look at the Silica Architech Yocto Linux community project for Zedboard:
