Hi; I've cc'd the main qemu-devel list and Andrew Baumann who contributed the rpi2 support. I know there are still some missing pieces to be added later but I forget the details. > Host 'uname -a' output: > Linux user-Precision-M4700 3.19.0-49-generic #55~14.04.1-Ubuntu SMP Fri Jan > 22 11:24:31 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux > > Qemu version (via apt-get) 2.5.50 > > > > I have been trying lately to get an emulation going with the raspi2 machine. > I admit that this is my first encounter with trying to use qemu, so perhaps > some of my attempts have been naive in their approach.
