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.

This part needs to be fixed ... since new u-boot auto detect HDMI / VGA and set output accordingly. I do detecting in first boot script and if you haven't plug HDMI at first boot, than it fix output to VGA.

Now you need to enable HDMI for kernel manually.

bin2fex /boot/script.bin /boot/script.fex
nano /boot/script.fex # screen0_output_type = 3 
fex2bin /boot/script.fex /boot/script.bin
reboot

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
