Thanks, I thought about something like that. I also changed the boot.cmd to: setenv bootargs console=tty1 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1920x1080p60 panic=10 consoleblank=0 enforcing=0 loglevel=1

Hi, is there a way to enable HDMI output for a cubietruck? During boot I get some display output till "starting kernel" than the screen gets black.
