Build 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 || exit cd build WORK=`pwd` echo $WORK  Clone basic Yocto layers: cd $WORK 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 git clone git://github.com/CogentEmbedded/meta-rcar.git 

 Switch to proper branches/commits   For Yocto v2.23.1 cd $WORK/poky git checkout -b tmp yocto-2.1.3 cd $WORK/meta-openembedded git checkout -b tmp 55c8a76da5dc099a7bc3838495c672140cedb78e cd $WORK/meta-linaro git checkout -b tmp 2f51d38048599d9878f149d6d15539fb97603f8f cd $WORK/meta-renesas git checkout -b tmp 7acbf5e2f99c59478adbc73c6a40d314589a3009 cd $WORK/meta-rcar git checkout -b v2.23.1 remotes/origin/v2.23.1   For Yocto v3.6.0 cd $WORK/poky git checkout -b tmp 16e22f3e37788afb83044f5089d24187d70094bd cd $WORK/meta-openembedded git checkout -b tmp 6e3fc5b8d904d06e3aa77e9ec9968ab37a798188 cd $WORK/meta-linaro git checkout -b tmp 30f0f5e158ba29c4b1ccfdd66f0368726e4179e0 cd $WORK/meta-renesas git checkout -b tmp 2f1825ea51179e3a7dbffead879a309d3b04494b cd $WORK/meta-rcar git checkout -b v3.6.0 remotes/origin/v3.6.0   Another versions are not tested for compatibility. Legacy BSP instruction can be found here R-Car Kingfisher legacy 

 This step is only for Yocto v2.23.1. Apply Linaro-GCC patch file: cd $WORK/meta-renesas export PATCH_DIR=meta-rcar-gen3/docs/sample/patch/patch-for-linaro-gcc patch -p1 < ${PATCH_DIR}/0001-rcar-gen3-add-readme-for-building-with-Linaro-Gcc.patch unset PATCH_DIR   Unzip downloaded proprietary driver modules to $WORK/proprietary folder. You should see the following files:   For Yocto v2.23.1 $ ls -1 $WORK/proprietary R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-20170828.zip R-Car_Gen3_Series_Evaluation_Software_Package_of_Linux_Drivers-20170828.zip </li>  For Yocto v3.6.0 $ ls -1 $WORK/proprietary/*.zip R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-20180326.zip R-Car_Gen3_Series_Evaluation_Software_Package_of_Linux_Drivers-20180409.zip </li> </ol> </li>

 Populate meta-renesas with proprietary software packages. export PKGS_DIR=$WORK/proprietary cd $WORK/meta-renesas sh meta-rcar-gen3/docs/sample/copyscript/copy_evaproprietary_softwares.sh -f $PKGS_DIR unset PKGS_DIR </li>

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

 Prepare default configuration files.   For Yocto v2.23.1 [m3ulcb] cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/m3ulcb/linaro-gcc/mmp/*.conf ./conf/ [h3ulcb] cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/h3ulcb/linaro-gcc/mmp/*.conf ./conf/

cd $WORK/build cp conf/local-wayland.conf conf/local.conf </li>  For Yocto v3.6.0 [m3ulcb] cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/m3ulcb/poky-gcc/mmp/*.conf ./conf/ [h3ulcb] cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/h3ulcb/poky-gcc/mmp/*.conf ./conf/

cd $WORK/build cp conf/local-wayland.conf conf/local.conf </li> </ol>

 Edit $WORK/build/conf/local.conf to enable/disable graphics and multimedia proprietary drivers support </li>

 Edit local.conf with evaluation packages requirements:   For Yocto v2.23.1 and later (to enable EVA_ prefix during packages install) DISTRO_FEATURES_append = " use_eva_pkg" </li> </ol> </li>

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

 Start the build

bitbake core-image-weston </li>

 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. </li>

<li> Bitbake has generated all the necessary files in ./tmp/deploy/images directory. You can verify its content: $ ls -1 `find ./tmp/deploy/images/m3ulcb/ -maxdepth 1 -type l -print` ./tmp/deploy/images/m3ulcb/core-image-weston-m3ulcb.cpio.gz ./tmp/deploy/images/m3ulcb/core-image-weston-m3ulcb.ext4 ./tmp/deploy/images/m3ulcb/core-image-weston-m3ulcb.manifest ./tmp/deploy/images/m3ulcb/core-image-weston-m3ulcb.tar.bz2 ./tmp/deploy/images/m3ulcb/Image ./tmp/deploy/images/m3ulcb/Image-m3ulcb.bin ./tmp/deploy/images/m3ulcb/Image-r8a7796-m3ulcb-kf.dtb ./tmp/deploy/images/m3ulcb/modules-m3ulcb.tgz ./tmp/deploy/images/m3ulcb/u-boot.bin ./tmp/deploy/images/m3ulcb/u-boot-elf-m3ulcb.srec ./tmp/deploy/images/m3ulcb/u-boot-elf.srec ./tmp/deploy/images/m3ulcb/u-boot-m3ulcb.bin Image is a Kernel image, *.dtb is a blob file, core-image-weston-m3ulcb.tar.bz2 is the rootfs, modules-m3ulcb.tgz are kernel modules. </li> <li> You can now proceed with running Yocto images </li> </ol>

After all these steps you can start working with boards and apps.

Build with MOST
MOST and GPS share the same R-CAR SoC pins and GPS is used by default. In order to use MOST one need to perform h/w modifications on KF board: move resistor from R661 -> R660 move resistor from R663 -> R662 And enable MOST in BSP by adding option to local.conf: KF_ENABLE_MOST = "1"

Build with SD3 (CN47)
SD3 and WIFI share the same R-CAR SoC resource and WIFI is used by default. In order to use SD on CN47 instead WIFI add following option to local.conf: KF_ENABLE_SD3 = "1"

Build SDK
After building image run this command to build SDK bitbake core-image-weston -c populate_sdk After build success the SDK installation script must appears in ./tmp/deploy/sdk directory: tmp/deploy/sdk/poky-glibc-x86_64-core-image-weston-aarch64-toolchain-2.1.3.sh To install SDK run this command and follow instructions on the screen: ./tmp/deploy/sdk/poky-glibc-x86_64-core-image-weston-aarch64-toolchain-2.1.3.sh

How to update of Sample Loader and MiniMonitor
New version: Sample Loader: V3.02 MiniMonitor: V3.02

Down load:

Why update?: ComEx Mechanical Specification: Durability: 30 mating cycles. This new version(V3.02) can update the firmware(*) while keeping Starter Kit(SK) and Kingfisher(KF) connected. (*)firmware: bootparam_sa0.srec, bl2-h3ulcb/m3ulcb.srec, cert_header_sa6.srec, bl31-h3ulcb/m3ulcb.srec, tee-h3ulcb/m3ulcb.srec, u-boot-elf.srec

How to update: <ol>

<li> Power off the KF and remove SK from KF </li> Turn off SW5 Remove SK from KF

<li> Set SW of SK as follows: </li> SW1:OFF SW6:OFF/OFF/OFF/OFF SW2:OFF/OFF/OFF/OFF

<li> Power on the SK (This means that you need to prepare a 5V AC-adapter for SK) </li> Press SW8 SCIF Download mode starts

<li> Send the following file from console(Ex: minicom): </li> type "ctrl+A S" and select upload method "ascii", then choose file for uploading the following file. Case of M3SK: BoardID_Writer_SCIF_64bit_ID=0x10(StarterKit-Pro_Rev1.0).mot Case of H3SK: BoardID_Writer_SCIF_64bit_ID=0x58(StarterKit-Premier_Rev1.0OB).mot

NOTE: Under Linux, if you got problem transferring this file, it may because of special character in its name.

Solution is to open a new terminal then manually launch the transfer with the following command with double quote around filename (Ex: serial link on ttyUSB0 for M3SK):
 * 1) /usr/bin/ascii-xfr -dsv "BoardID_Writer_SCIF_64bit_ID=0x10(StarterKit-Pro_Rev1.0).mot" > /dev/ttyUSB0

You can confirm the following log (Ex: M3SK): +-+ +-+ Product Code : R-Car M3 ES1.0
