Interface demo is not functioning

Other Parts Discussed in Thread: OMAP3530

Good day! I'm trying to run interface demo from EVM board. I'm going to /opt/dvsdk/omap3530, run loadmodules.sh and then:

root@arago:/opt/dvsdk/omap3530# ./interface
Demo interface started at level 0.
<3>omapfb omapfb: enable overlay failed
omapfb omapfb: enable overlay failed

The program does not exit, but I see nothing on LCD screen. Any ideas?

P.S. Decoding demo works just fine both for LCD and DVI.

Make sure you have 'omapfb.rotate=1 omapfb.rotate_type=1 omap_vout.vid1_static_vrfb_alloc=y' in your bootargs variable within U-boot as shown in the GSG, if you don't have these in there you will get the error you mention.

I have Graphics SDK demo that requires no rotation, so I have to take those two rotating stuff out. Then I got overlay failed message when running interface demo (But using DVI output, it worked fine). Any suggestions on how I can have one setup to be able to run both demos? Thanks.
