I'm trying to get some output over the HDMI from my SABRE board but I'm not getting anything. I'm using a standard HDMI cable connected to a SAMSUNG HDMI monitor, no converters, and I've verified the monitor and the cable work just fine via another input source.


I'm using a 6SX SABRE SDB board... either rev C (SCH-27962 REV C) or A2 (700-27962 REV A2), there's two stickers on the back. On the LCD expansion port (J11) I've connected a Freescale HDMI Port Card (SCH-26673 REVC3/700-26673 REV F).


All the connections seem sound, but I never see anything on the display. I've built both the fsl-image-gui and the fsl-image-qt5 image (with framebuffer backend) but neither seem to output anything. I did some searching and thought it might be a problem with the boot args, another thread got me thinking about that, I tried updating my boot arguments to:


setenv mmcargs 'setenv bootargs console=${console},${baudrate} root=/dev/mmcblk2p2 rootwait rw video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'


but still no luck. How should I go about figuring out this issue? any thoughts?
