Introduction
This page contains information on building and running Yocto on:
 * Infotainment Carrier Board For R-Car Starter Kit(Kingfisher)

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.

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:
 * https://www.renesas.com/us/en/solutions/automotive/rcar-download/rcar-demoboard.html
 * Download two files:
 * R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-20190722.zip
 * R-Car_Gen3_Series_Evaluation_Software_Package_of_Linux_Drivers-20190722.zip
 * Graphic drivers are required for Wayland. Multimedia drivers are optional.
 * 1) Install required packages
 * Ubuntu and Debian
 * Fedora
 * Refer to Yocto Project Quick Start for more information.

Build using script
This example is for Kingfisher with H3ULCB board. If you use other board, you need to modify the script.
 * 1) Directory Structure
 * 2) Build script(build.sh)
 * 3) build
 * If the build completes successfully, all the necessary files are generated in a following directory:
 * 1) build
 * If the build completes successfully, all the necessary files are generated in a following directory:
 * If the build completes successfully, all the necessary files are generated in a following directory:

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.
 * 1) Clone basic Yocto layers:
 * 2) Switch to proper branches/commits (2020/02/20 updated)
 * Another versions are not tested for compatibility.
 * Legacy BSP instruction can be found here R-Car Kingfisher Yocto Gen3 legacy
 * 1) Download proprietary driver modules to $WORK/proprietary folder
 * You should see the following files:
 * 1) Populate meta-renesas with proprietary software packages.
 * 2) Setup build environment
 * 3) Prepare default configuration files.
 * NOTE: extra configuration examples are available in the following directory:
 * 1) (Edit $WORK/build/conf/local.conf to enable/disable graphics and multimedia proprietary drivers support)
 * 2) Edit local.conf with evaluation packages requirements:
 * 3) Add layer meta-rcar
 * 4) Start the build
 * 5) 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:
 * and the command prompt should return.
 * 1) Bitbake has generated all the necessary files in ./tmp/deploy/images directory. You can verify its content:
 * 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.
 * 1) You can now proceed with running Yocto images
 * 1) Edit local.conf with evaluation packages requirements:

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:

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:

Build with LVDS panel(CN49)
Yocto v3.13.0 or later supports the following LVDS panels. How to select:
 * Add following option to local.conf:

Build with CN11
CN11 is available on kigfisher board + R-Car Starter Kit Premier(H3) only. CN11 and CN29/48(CMOS/CSI) share the same R-Car SoC pins and CN29/CN48 is used by default. In order to use CN11 instead CN29/48(CMOS/CSI), add following option to local.conf:

Build SDK
Refer to Build SDK on the Yocto-Gen3 page.

Running Yocto images
Refer to Running Yocto images on the Yocto-Gen3 page. [NOTE]
 * DTB filename for Kingfisher contains suffix "-kf".
