Build Yocto image
 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`  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 git clone git://github.com/CogentEmbedded/meta-rcar.git 

 Switch to proper branches/commits   For Yocto v3.9.0 cd $WORK/poky git checkout -b tmp 342fbd6a3e57021c8e28b124b3adb241936f3d9d cd $WORK/meta-openembedded git checkout -b tmp dacfa2b1920e285531bec55cd2f08743390aaf57 cd $WORK/meta-linaro git checkout -b tmp 75dfb67bbb14a70cd47afda9726e2e1c76731885 cd $WORK/meta-renesas git checkout -b tmp fd078b6ece537d986852cb827bd21e022a797b2f cd $WORK/meta-rcar git checkout -b v3.9.0 remotes/origin/v3.9.0   For Yocto v3.13.0 (Note: https://elinux.org/R-Car/Boards/Yocto-Gen3#Known_issues_and_limitations (No.3)) 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 00f70f062aace04c051fa92d3cd7b887718fc313 cd $WORK/meta-rcar git checkout -b v3.13.0 remotes/origin/v3.13.0 

 Please get the proprietary package for R-Car M3N from the your company's distributer. And copy them to $WORK/proprietary folder. 

 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 $PKGS_DIR unset PKGS_DIR 

 Setup build environment cd $WORK source poky/oe-init-build-env </li>

 Prepare default configuration files.  cp $WORK/meta-rcar/meta-rcar-gen3-adas/docs/sample/conf/m3nulcb/poky-gcc/mmp/*.conf ./conf/ cd $WORK/build cp conf/local-wayland.conf conf/local.conf </li>

 Add layer meta-rcar : bitbake-layers add-layer ../meta-rcar/meta-rcar-gen3-adas </li>

 Start the build

bitbake core-image-weston </li> </ol>
