How to build

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 gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat cpio python3 python3-pip python3-pexpect \
xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa \
libsdl1.2-dev pylint3 xterm libarchive-zip-perl

Build script

  1. Build script(build.sh)
    #!/bin/bash
    
    WORK=`pwd`/s4sk_proto
    s4sk_proto
    META_RENESAS_COMMIT=b3745d99266782e38a9b627ba207537c180f43e3
    
    mkdir -p ${WORK}
    cd ${WORK}
    
    git clone git://git.yoctoproject.org/poky
    git clone git://git.openembedded.org/meta-openembedded
    git clone https://github.com/renesas-rcar/meta-renesas
    
    # Switch to proper branches/commits
    cd $WORK/poky
    git checkout -b tmp 74b22db6879b388d700f61e08cb3f239cf940d18
    cd $WORK/meta-openembedded
    git checkout -b tmp 814eec96c2a29172da57a425a3609f8b6fcc6afe
    cd $WORK/meta-renesas
    git checkout -b tmp ${META_RENESAS_COMMIT}
    
    cd $WORK
    source $WORK/poky/oe-init-build-env build
    cp $WORK/meta-renesas/meta-rcar-gateway/docs/sample/conf/s4sk-proto/poky-gcc/bsp/*.conf conf/
    
    bitbake rcar-image-gateway
    
  2. build
    ./build.sh
    
    If the build completes successfully, all the necessary files are generated in a following directory:
    ./s4sk_proto/build/tmp/deploy/images/s4sk-proto/
    

Manual steps

  1. Create a directory and switch to it
    Warning! Yocto builds require a lot of disk space (up to 100 GB). Make sure you have got enough before starting the build.
    mkdir build
    cd build
    export WORK=`pwd`
    
  2. Clone basic Yocto layers:
    cd $WORK
    git clone git://git.yoctoproject.org/poky
    git clone git://git.openembedded.org/meta-openembedded
    git clone https://github.com/renesas-rcar/meta-renesas
    
  3. Switch to proper branches/commits
    cd $WORK/poky
    git checkout -b tmp 74b22db6879b388d700f61e08cb3f239cf940d18
    cd $WORK/meta-openembedded
    git checkout -b tmp 814eec96c2a29172da57a425a3609f8b6fcc6afe
    cd $WORK/meta-renesas
    git checkout -b tmp b3745d99266782e38a9b627ba207537c180f43e3
    
  4. Setup build environment
    cd $WORK
    source poky/oe-init-build-env $WORK/build
    
  5. Prepare default configuration files.
    cp $WORK/meta-renesas/meta-rcar-gateway/docs/sample/conf/s4sk-proto/poky-gcc/bsp/*.conf conf/ ./conf/
    cd $WORK/build
    
  6. Start the build
    bitbake rcar-image-gateway
    
  7. 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 4956 tasks of which 5 didn't need to be rerun and all succeeded.
    
    and the command prompt should return.
  8. Bitbake has generated all the necessary files in ./tmp/deploy/images directory.
    You can verify its content:
    $ ls -1 `find ./tmp/deploy/images/s4sk-proto/  -maxdepth 1 -type l -print`
    ./tmp/deploy/images/s4sk-proto/Image
    ./tmp/deploy/images/s4sk-proto/Image-s4sk-proto.bin
    ./tmp/deploy/images/s4sk-proto/modules-s4sk-proto.tgz
    ./tmp/deploy/images/s4sk-proto/r8a779f0-s4sk-prototype-s4sk-proto.dtb
    ./tmp/deploy/images/s4sk-proto/r8a779f0-s4sk-prototype.dtb
    ./tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.manifest
    ./tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.tar.bz2
    ./tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.testdata.json
    ./tmp/deploy/images/s4sk-proto/u-boot-elf-s4sk-proto.srec
    ./tmp/deploy/images/s4sk-proto/u-boot-elf.srec
    ./tmp/deploy/images/s4sk-proto/u-boot-initial-env
    ./tmp/deploy/images/s4sk-proto/u-boot-initial-env-s4sk-proto
    ./tmp/deploy/images/s4sk-proto/u-boot-s4sk-proto.bin
    ./tmp/deploy/images/s4sk-proto/u-boot.bin
    
    Image is a Kernel image, r8a779f0-s4sk-prototype.dtb is a blob file, rcar-image-gateway-s4sk-proto.tar.bz2 is the rootfs, modules-s4sk-proto.tgz is kernel modules.

How to boot

Loading kernel and rootfs via SD card

This section describes steps that are necessary for preparing and booting from SD card.

Preparing SD card

WARNING! These steps will erase the SD card completely. In short, all files will be lost.
In order to prepare you SD card, follow these instructions on host machine:

  1. Partion your SD card to set 1 partition and ID=83 (Linux)
    Make sure the SD card doesn't contain any important files.
    $ fdisk /dev/mmcblk0
    -> d
    -> n
    -> p
    -> 1
    -> t
    -> 83
    
  2. Format this partition to ext4
    $ mkfs.ext4 /dev/mmcblk0p1
    
  3. Mount this partition on your host to any directory and upack the rcar-image-gateway-s4sk-proto.tar.bz2 into mounted folder.
    $ mount /dev/mmcblk0p1 /mnt
    $ cd <your_yocto_build_directory>
    $ tar xfj build/tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.tar.bz2  -C /mnt
    
    NOTE: probably you need to be a root user, hence use "sudo"

Configure U-Boot to boot from SD card

  • Proper U-Boot command to boot from SD:
    # setenv bootargs 'console=ttySC0,921600 rw root=/dev/mmcblk0p1 rootwait'
    # ext4load mmc 0:1 0x48080000 /boot/Image
    # ext4load mmc 0:1 0x48000000 /boot/r8a779f0-s4sk-prototype.dtb
    # booti 0x48080000 - 0x48000000
    
  • Example of U-Boot environment variables:
    baudrate=921600
    bootargs=root=console=ttySC0,921600 rw root=/dev/mmcblk0p1 rootwait
    bootcmd=ext4load mmc 0:1 0x48080000 /boot/Image; ext4load mmc 0:1 0x48000000 /boot/r8a779f0-s4sk-prototype.dtb; booti 0x48080000 - 0x48000000
    bootdelay=2
    bootm_size=0x10000000
    fdtcontroladdr=bbf45160
    loadaddr=0x58000000
    platform=r8a779f0
    stderr=serial@e6540000
    stdin=serial@e6540000
    stdout=serial@e6540000
