Yocto versions

Poky-2.4.3 is supported with Yocto v3.21.0.
Specific commit of meta-openembedded is required.

Host PC

Ubuntu 16.04 LTS (64bit) is recommended as OS. 32bit version is not supported.

Preliminary steps

  1. Please get the proprietary package for R-Car M3N from the your company's distributer.
  2. Install required packages
    Ubuntu and Debian 
    sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
     build-essential chrpath socat libsdl1.2-dev xterm python-crypto cpio python python3 \
     python3-pip python3-pexpect xz-utils debianutils iputils-ping libssl-dev

    Refer to Yocto Project Quick Start for more information.

Building the BSP for R-Car Starter Kit Pro(M3N)

Build using script

  1. Directory Structure 
    |--build.sh
`--proprietary
   `-- <Proprietary package for R-Car M3N>
  2. Build script(build.sh) 
    #!/bin/bash

TARGET_BOARD=m3nulcb

# Create a directory and switch to it
mkdir ${TARGET_BOARD}
cd ${TARGET_BOARD}
WORK=`pwd`

# Clone basic Yocto layers in parallel
git clone git://git.yoctoproject.org/poky &
git clone git://git.linaro.org/openembedded/meta-linaro.git &
git clone git://git.openembedded.org/meta-openembedded &
git clone git://github.com/renesas-rcar/meta-renesas &
# If you use Kingfisher, below is also necessary
#git clone git://github.com/CogentEmbedded/meta-rcar.git &

# Wait for all clone operations
wait

# Switch to proper branches/commits
cd $WORK/poky
git checkout -b tmp 7e7ee662f5dea4d090293045f7498093322802cc
cd $WORK/meta-openembedded
git checkout -b tmp 352531015014d1957d6444d114f4451e241c4d23
cd $WORK/meta-linaro
git checkout -b tmp 75dfb67bbb14a70cd47afda9726e2e1c76731885
cd $WORK/meta-renesas
git checkout -b tmp ad3a8cfee5b6a6fab17cf1c6e5af851eaec75bd7
# If you use Kingfisher, below is also necessary
#cd $WORK/meta-rcar
#git checkout -b v3.21.0 remotes/origin/v3.21.0

# Populate meta-renesas with proprietary software packages
cd $WORK/meta-renesas
sh meta-rcar-gen3/docs/sample/copyscript/copy_proprietary_softwares.sh -f $WORK/../proprietary

cd $WORK
source poky/oe-init-build-env $WORK/build

#cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/${TARGET_BOARD}/poky-gcc/bsp/*.conf ./conf/.
#cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/${TARGET_BOARD}/poky-gcc/gfx-only/*.conf ./conf/.
cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/${TARGET_BOARD}/poky-gcc/mmp/*.conf ./conf/

cd $WORK/build
cp conf/local-wayland.conf conf/local.conf

# If you use Kingfisher, below is also necessary
#bitbake-layers add-layer ../meta-rcar/meta-rcar-gen3-adas

bitbake core-image-weston
  3. build 
    ./build.sh

If the build completes successfully, all the necessary files are generated in a following directory: 

  1. ./<target_board_name>/build/tmp/deploy/images/<target_board_name>

Build using 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 git://git.linaro.org/openembedded/meta-linaro.git
git clone git://github.com/renesas-rcar/meta-renesas
    If you use Kingfisher, below is also necessary. 
    git clone git://github.com/CogentEmbedded/meta-rcar.git
  3. Switch to proper branches/commits 
    cd $WORK/poky
git checkout -b tmp 7e7ee662f5dea4d090293045f7498093322802cc
cd $WORK/meta-openembedded
git checkout -b tmp 352531015014d1957d6444d114f4451e241c4d23
cd $WORK/meta-linaro
git checkout -b tmp 75dfb67bbb14a70cd47afda9726e2e1c76731885
cd $WORK/meta-renesas
git checkout -b tmp ad3a8cfee5b6a6fab17cf1c6e5af851eaec75bd7
    If you use Kingfisher, below is also necessary. 
    cd $WORK/meta-rcar
git checkout -b v3.21.0 remotes/origin/v3.21.0
    Another versions are not tested for compatibility.
    Legacy BSP instruction can be found here R-Car M3NSK Yocto Gen3 legacy
  4. Please get the proprietary package for R-Car M3N from the your company's distributer. And copy them to $WORK/proprietary folder.
  5. Populate meta-renesas with proprietary software packages. 
    export PKGS_DIR=$WORK/proprietary
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
source poky/oe-init-build-env $WORK/build
  7. Prepare default configuration files. 
    cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/m3nulcb/poky-gcc/mmp/*.conf ./conf/
cd $WORK/build
cp conf/local-wayland.conf conf/local.conf
  8. If you use Kingfisher, add layer meta-rcar. 
    bitbake-layers add-layer ../meta-rcar/meta-rcar-gen3-adas
  9. Start the build 
    bitbake core-image-weston
