Is it possible for you to enable low-level debugging and pass omapfb.debug=1 omapdss.debug=1 in your bootargs? This would show the Framebuffer and DSSDBG prints. We would get an idea if kernel is getting stuck in DSS/OMAPFB. Let me know if you any help in enabling debug prints. Also one more suggestion/ question, are you seeing a hang if DSS is not enabled in kernel? -Thanks, Mayuresh > > Have the HDMI on your setup worked in any (prebuilt) image?
