Since I don't have a Pi yet, I am trying to emulate one with qemu. Here is the command line I'm currently trying: qemu-system-arm -cpu arm1136-r2 -m 256 -M versatilepb -serial stdio -hda freebsd-pi-20121130.img.gz It tells me "Kernel image must be specified". How can I get a kernel image to satisfy this request? Many thanks to the people performing this work, and also the beagleboard and beaglebone work! I hope to live long enough to see the day these platforms are promoted to tier 1 status in FreeBSD! -- George Mitchell
