Not sure anyone cares but to get the demo beagleboard-xM build with gnome working with gstreamer and cmem you have to allocate memory for the cmem.
All the examples give mem=99M@0x80000000 mem=384M@0x88000000 but this fails. I modified the loadmodules.sh to use memory above the kernel and not segment the memory allocated for the kernel. As a test I picked 400 meg as a random try. so optargs="mem=400M@0x80000000" I then altered loadmodules.ch modprobe cmemk allowOverlap=1 phys_start=0x99300000 phys_end=0x9a300000 \ pools=1x5250000,6x829440,1x345600,1x691200,1x1 above the 400M instead of attempting to put it in the middle like the examples. Works fine although I am wasting memory but tuning is easy... Hope that helps someone while I struggle with a custom build...
