Bootstraping and image for Erle-Brain

Image you'd like to create a File System image to develop for Erle-Brain in your local machine. How would you do that without having to start from one of our own images.

That's exactly what would be covered here.

Creating the image

mkdir ~/vivid
qemu-debootstrap --arch=armhf vivid ~/vivid/

Mounting the images

apt-get install qemu-user-static
sudo cp /usr/bin/qemu-arm-static ~/vivid/usr/bin/
sudo mount -o bind /dev ~/vivid/dev
sudo mount -o bind /proc ~/vivid/proc
sudo mount -o bind /sys ~/vivid/sys

Next comes the magic. This registers the ARM executable format with the QEMU static binary. Thus, the path to qemu-arm-static has to match where it is located on the host and slave systems:

echo ':arm:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00:\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff:/usr/bin/qemu-arm-static:' > /proc/sys/fs/binfmt_misc/register

chroot into it:

chroot ~/vivid
