Iam trying to run multicore DFB application on my arm based device.
I have modprobed fusion.ko, created the /dev/fusion nodes and also did
"mount tmpfs /dev/shm -ttmpfs "
I configured DFB thus:
./configure
--host=arm-linux --build=i386-linux --target=arm --srcdir=`pwd`
--prefix=$PREFIX --libdir=$PREFIX/lib --libexecdir=$PREFIX/libexec
--include=$PREFIX/include --disable-x11 --enable-debug --disable-voodoo
--disable-mmx disable-see --disable-sdl --enable-jpeg --enable-png
--enable-gif --enable-freetype --enable-fbdev --disable-video4linux
--disable-video4linux2 --with-gfxdrivers=none
--with-inputdrivers=linuxinput --enable-multi
When I run
[r...@bb bin]# ./arm-dfbmaster

so when run this:

Questions:1. video-phys - Is it the physical address of /dev/fb/0?, why do I
need to provide that?
2. Why do I get the "No layers available"?
