Installation of required tools and libraries
Ubuntu is used as Linux Host PC since Yocto Project Quick Start specifies Ubuntu as one of the distributions. You need to install the required packages as follows.
sudo apt-get install -y gawk wget diffstat texinfo chrpath socat \ libsdl1.2-dev python-crypto checkpolicy python3-git python3-github \ bzr pigz m4 lftp openjdk-8-jdk git-core gnupg flex \ bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib \ libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev \ ccache libgl1-mesa-dev libcap-ng-dev libxml2-utils xsltproc unzip \ python-clang-6.0 gcc-7 g++-7 bc python3-pyelftools python3-pip \ python3-crypto libpixman-1-dev libcap-dev device-tree-compiler libffi-dev \ python-dev libgit2-dev ninja-build curl

Manual steps
- Install moulin
pip3 install --upgrade pip export PATH="$PATH:${HOME}/.local/bin" pip3 install --user git+https://github.com/xen-troops/moulin
- Build
mkdir build-xen cd build-xen export WORK_XEN=`pwd` curl -O https://raw.githubusercontent.com/renesas-rcar/meta-xt-prod-devel-rcar-gen4/s4sk-mp-1.0/prod-devel-rcar-s4sk.yaml moulin prod-devel-rcar-s4sk.yaml --ENABLE_DOMU=yes ninja
- Building image can take up to a few hours depending on your host system performance.
After the build has been completed successfully, you should see the output similar to:NOTE: Tasks Summary: Attempted 2734 tasks of which 1752 didn't need to be rerun and all succeeded.

How to boot
Micro SD card(32GB or more) boot
WARNING! These steps will erase the SD card completely. In short, all files will be lost.
Follow these steps on the host machine:
NOTE: probably you need to be a root user, hence use "sudo". And "mmcblk0" should be adapted to your environment (eg., sdb or sdc).
- Delete all the partitions in the SD card. Below is an example for one partition, repeat the process for all the remaining partitions in the SD card if exists.
Ex) $ fdisk /dev/mmcblk0 Command (m for help): d Partition number (2-4, default 1): 1 (number of the first partion) Partition 1 has been deleted.
- Divide the SD card into three partions and set ID=83(Linux) for each.
Ex) $ fdisk /dev/mmcblk0 Command (m for help): n Partition type p primary (0 primary, 0 extended, 4 free) e extended (container for logical partitions) Select (default p): p Partition number (1-4, default 1): 1 (number of the first partion) First sector (2048-62333951, default 2048): <Hit Enter key> Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-62333951, default 62333951): +9G (Size of the first partion) Created a new partition 1 of type 'Linux' and of size 9 GiB. Partition #1 contains a ext4 signature. Do you want to remove the signature? [Y]es/[N]o: n Command (m for help): t Selected partition 1 Hex code (type L to list all codes): 83 Changed type of partition 'Linux' to 'Linux'.
- Repeat the above commands for the second and third partitions by changing the partition number to 2 and 3.
- Format each partition to ext4
$ mkfs.ext4 /dev/mmcblk0p1 $ mkfs.ext4 /dev/mmcblk0p2 $ mkfs.ext4 /dev/mmcblk0p3
- Write images to partitions of SD card
$ mount /dev/mmcblk0p1 /mnt $ cp ${WORK_XEN}/yocto/build-dom0/tmp/deploy/images/generic-armv8-xt/Image /mnt $ cp ${WORK_XEN}/yocto/build-dom0/tmp/deploy/images/generic-armv8-xt/uInitramfs /mnt $ cp ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/r8a779f0-s4sk-xen.dtb /mnt $ cp ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/xen-uImage /mnt/ $ cp ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/xenpolicy-s4sk /mnt $ cp ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/boot-emmc.uImage /mnt $ sync $ umount /mnt $ mount /dev/mmcblk0p2 /mnt $ tar jxf ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/rcar-image-minimal-s4sk.tar.bz -C /mnt $ sync $ umount /mnt $ mount /dev/mmcblk0p3 /mnt $ tar jxf ${WORK_XEN}/yocto/build-domu/tmp/deploy/images/s4sk/rcar-image-minimal-s4sk.tar.bz2 -C /mnt $ sync $ umount /mnt

Tips
Writing an image to Micro SD using the dd command
This frees you from confusing Micro SD partitioning, formatting, and other procedures.
- build (See R-Car/Boards/S4SK/Xen-Hypervisor#How_to_build)
./build.sh
- or
ninja
- Generated the "full.img" file
ninja image-full
ls build.ninja full.img prod-devel-rcar-s4sk.yaml yocto
- Writing the "full.imge" to Micro SD
dd if=full.img of=/dev/mmcblk0
- Boot
setenv initrd_high 0xffffffffffffffff setenv bootargs setenv bootcmd 'run bootcmd_sdcard' setenv bootcmd_sdcard 'run sdcard_xen_load; run sdcard_dtb_load; run sdcard_kernel_load; run sdcard_xenpolicy_load; run sdcard_initramfs_load; bootm 0x48080000 0x84000000 0x48000000' setenv sdcard_dtb_load 'ext4load mmc 0:1 0x48000000 xen.dtb; fdt addr 0x48000000; fdt resize; fdt mknode / boot_dev; fdt set /boot_dev device mmcblk0' setenv sdcard_initramfs_load 'ext4load mmc 0:1 0x84000000 uInitramfs' setenv sdcard_kernel_load 'ext4load mmc 0:1 0x7a000000 Image' setenv sdcard_xen_load 'ext4load mmc 0:1 0x48080000 xen' setenv sdcard_xenpolicy_load 'ext4load mmc 0:1 0x7c000000 xenpolicy' run bootcmd
NFS boot
- Install some packages for NFS boot on Host PC (See R-Car/Boards/Yocto-Gen3/v5.9.0#Loading_kernel_via_TFTP_and_rootfs_via_NFS)
- Copy and decompress the some files and rootfs on Host PC
Ex) $ mkdir -p /srv/tftp/s4/rootfs_xen/dom0 /srv/tftp/s4/rootfs_xen/domd /srv/tftp/s4/rootfs_xen/domu $ export NFS_ROOT=/srv/tftp/s4/rootfs_xen $ cp ${WORK_XEN}/yocto/build-dom0/tmp/deploy/images/generic-armv8-xt/Image ${NFS_ROOT}/dom0 $ cp ${WORK_XEN}/yocto/build-dom0/tmp/deploy/images/generic-armv8-xt/uInitramfs ${NFS_ROOT}/dom0 $ cp ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/r8a779f0-s4sk-xen.dtb ${NFS_ROOT}/dom0 $ cp ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/xen-uImage ${NFS_ROOT}/dom0 $ cp ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/xenpolicy-s4sk ${NFS_ROOT}/dom0 $ tar jxf ${WORK_XEN}/yocto/build-domd/tmp/deploy/images/s4sk/rcar-image-minimal-s4sk.tar.bz -C ${NFS_ROOT}/domd $ tar jxf ${WORK_XEN}/yocto/build-domu/tmp/deploy/images/s4sk/rcar-image-minimal-s4sk.tar.bz2 -C ${NFS_ROOT}/domu
