As the other suggestion said, you need the DTB for the system you are emulating too. This is how ARM systems work these days. I suspect you want the file: ./usr/lib/linux-image-3.16.0-4-armmp/vexpress-v2p-ca9.dtb If you decide to emulate the a15 vexpress (which many examples use I have noticed, although perhaps more if doing kvm on an actual arm) you would want ./usr/lib/linux-image-3.16.0-4-armmp/vexpress-v2p-ca15-tc1.dtb instead. -- Len Sorensen
