Required packages

  1. Download evaluation version of proprietary graphics and multimedia drivers from Renesas.
    To download Multimedia and Graphics library and related Linux drivers, please use the following link:
    Download two files:
    • R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-20220121.zip
    • R-Car_Gen3_Series_Evaluation_Software_Package_of_Linux_Drivers-20220121.zip

    Graphic drivers are required for Wayland. Multimedia drivers are optional.
  2. Install required packages
    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 \

    Refer to Yocto Project Quick Start for more information.

Building the BSP for CCPF-SK

What is different between "MMP" and "MMP-dist".

  • MMP is minimal BSP which contains GFX/MMP evaluation package.
  • MMP-dist is MMP + some additional packages(For debug, development, benchmark, and so on).
  • MMP-dist release package(core-image-weston-release) is distributed on R-Car/Boards/CCPF-SK/GettingStarted
  • BSP is minimal BSP without GFX/MMP evaluation package.

Manual steps for building MMP


  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
    git clone https://github.com/renesas-rcar/meta-renesas-ccpf
  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 c5b39adbabdb8fd51517cf37190552b8fb57d062 # <-- 2023/01/18 updated
    cd $WORK/meta-renesas-ccpf
    git checkout -b tmp 09dd815616cce3a2bdcf8906c0d21403df8b93bd
    Another versions are not tested for compatibility.
  4. Create $WORK/../proprietary folder, then download proprietary driver modules to it.
    See also Required_packages
    You should see the following files:
    $ ls -1 $WORK/../proprietary/*.zip
  5. Populate meta-renesas with proprietary software packages.
    export PKGS_DIR=$WORK/../proprietary
    cd $PKGS_DIR
    unzip -qo R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-20220121.zip 
    unzip -qo R-Car_Gen3_Series_Evaluation_Software_Package_of_Linux_Drivers-20220121.zip
    cd $WORK/meta-renesas
    sh meta-rcar-gen3/docs/sample/copyscript/copy_proprietary_softwares.sh -f $PKGS_DIR
    unset PKGS_DIR
  6. Setup build environment
    cd $WORK
    TEMPLATECONF=$PWD/meta-renesas-ccpf/meta-rcar-gen3/docs/sample/conf/<h3ulcb|m3ulcb>-ccpf-sk/mmp/ \
        source poky/oe-init-build-env ${WORK}/build
  7. Start the build
    bitbake core-image-weston
  8. 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 4704 tasks of which 31 didn't need to be rerun and all succeeded.
    and the command prompt should return.
  9. Bitbake has generated all the necessary files in ./tmp/deploy/images directory.
    You can verify its content:
    bash $ ls -1 `find ./tmp/deploy/images/h3ulcb/ -maxdepth 1 -type l -print`
    Image is a Kernel image, *.dtb is a blob file, core-image-<image_type>-<board_name>.tar.bz2 is the rootfs, modules-<board_name>.tgz are kernel modules.
  10. You can now proceed with Running Yocto images

fan control

To use the fan control function, RL78 needs to be updated.

Temperature fan speed
less than 35 degrees 0%
above 35 degrees and below 50 degrees 50%
above 50 degrees 100%

This function can be stopped by "systemctl stop ccpfsk-fancontrol".
