This buildroot fork will produce a very light-weight and trimmed down toolchain, rootfs and kernel for the multiple targets, including the Raspberry Pi 2. Mainly focused on enabling all HTML5 features WebKit in multiple ports.
You will need to install some packages on your host machine, for e.g. on Ubuntu 12.04:
sudo apt-get install build-essential git subversion cvs unzip whois ncurses-dev bc mercurial
For host machines with kernel 3.8 or higher (e.g. Ubuntu 13.04) you can use the experimental F2FS filesystem:
sudo apt-get install build-essential git subversion cvs unzip whois ncurses-dev bc mercurial f2fs-tools
When creating a VM please allocate a minimal of 30GB disk space.
git clone git://github.com/metrological/buildroot.git
or
git clone https://github.com/metrological/buildroot.git
followed by
cd buildroot
Select a browser distribution for Qt5WebKit (qtbrowser)
make rpi2_qt5webkit_defconfig
or for WebKit Wayland (wpe)
make rpi2_wpe_defconfig
If you want to add additional packages
make menuconfig
Start the build (NOTICE: Don't use the -j switch, it's set to auto-detect)
make
You will need to create two partitions on your sdcard and copy files to the appropriate partitons.
The first (boot) is a small W95 FAT32 (LBA) partition of about 100 MB in size.
Notice you will need to replace sdx in the following commands with the actual device node for your sdcard.
# run the following as root
mkfs.vfat -F 32 -n boot /dev/sdx1
mkdir -p /media/boot
mount /dev/sdx1 /media/boot
You will need to copy all the files in output/images/rpi-firmware and the kernel from output/images/zImage to your boot partition.
# run the following as root
cp output/images/rpi-firmware/* /media/boot
cp output/images/zImage /media/boot
sync
umount /media/boot
The second (rootfs) can be as big in size as you prefer, but with a 200 MB minimum. It should be formatted as ext4.
# run the following as root
mkfs.ext4 -L rootfs /dev/sdx2
mkdir -p /media/rootfs
mount /dev/sdx2 /media/rootfs
You will need to extract output/images/rootfs.tar to the partition, as root.
# run the following as root
tar -xvpsf output/images/rootfs.tar -C /media/rootfs # replace with your mount directory
sync
umount /media/rootfs
You can login to the system using ssh. The default password is set to root. It is configurable with make menuconfig.
ssh root@192.168.1.100 # replace with your ip address
