Tizen ARM64 Development

This wiki page describes arm64 development status for Tizen 3.0. Only arm, i586, x86_64 are only supported before we added the arm64 architecture. At present, only common profile will support arm64 architecture. Mobile profile will support the arm64 architecture later.

Supported Hardwares

  • Common profile
    • QEMU
    • ARM Juno board
  • Mobile profile
    • TBD

Toolchain & ARM64 Packages

Toolchain

  • gcc
  • glibc
  • binutils

ARM64 Packages

  • crosswalk

How to run ARM64 Platform

ARM64 Kernel

  • Download linaro cross compiler
wget http://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux.tar.xz
tar xf gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux.tar.xz
ln -sf gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux gcc-linaro-aarch64
export PATH=~/gcc-linaro-aarch64/bin:$PATH

ARM64 Platform Image

  • The official snapshot image for arm64 is not published yet. But, we can make the image by editing an arm kickstart file.
wget http://download.tizen.org/snapshots/tizen/common/latest/images/arm-wayland/common-wayland-3parts-armv7l-odroidu3/tizen-common_20141107.2_common-wayland-3parts-armv7l-odroidu3.ks
cp tizen-common_20141107.2_common-wayland-3parts-armv7l-odroidu3.ks tizen-common-arm64.ks

  • Install the latest mic tool(>=0.26) to support arm64 correctly
mic --version
wget http://download.tizen.org/tools/pre-release/Ubuntu_14.04/all/mic_0.26_all.deb
sudo dpkg -i mic_0.26_all.deb
  • Generate an arm64 image
sudo mic cr loop -A aarch64 tizen-common-arm64.ks

Running an arm64 image on QEMU

Install qemu-system-aarch64 for emulating arm64 architecture

  • Download source from qemu repository
git clone http://git.qemu.org/git/qemu.git
  • Prerequisites for compiling qemu
sudo apt-get install libsdl-dev libcurl4-nss-dev libpixman-1-dev libfdt-dev libcap-dev
  • Compile qemu-system-aarch64
./configure --target-list=aarch64-softmmu --enable-modules --enable-system --disable-user --enable-kvm --enable-sdl --enable-curl --enable-virtfs --enable-fdt --enable-vhost-net
make -j4
sudo make install
  • Convert ext4 loop image to qcow2 image
qemu-img convert -O qcow2 rootfs.img rootfs.qcow2
  • Run qemu-system-aarch64 with tizen image
qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic -smp 1 -m 1024 \
	-drive file=mic-output/rootfs.qcow2,if=none,id=rootfs -device virtio-blk-device,drive=rootfs \
	-kernel ../linux/arch/arm64/boot/Image \
	-netdev user,id=unet -device virtio-net-device,netdev=unet \
