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

Host PC
Ubuntu 16.04/20.04 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/application/automotive/r-car-h3-m3-h2-m2-e2-documents-software
 * 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.
 * 1) Install required packages
 * Refer to Yocto Project Quick Start for more information.
 * Refer to Yocto Project Quick Start for more information.
 * Refer to Yocto Project Quick Start for more information.

Using build script

 * 1) Directory Structure
 * 2) Build script(build.sh)
 * 3) build
 * target_board_name is "h3ulcb" or "m3ulcb".
 * If the build completes successfully, all the necessary files are generated in a following directory:
 * target_board_name is "h3ulcb" or "m3ulcb".
 * 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:

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
 * Another versions are not tested for compatibility.
 * Legacy BSP instruction can be found here R-Car Kingfisher Yocto Gen3 legacy
 * 1) Create $WORK/../proprietary folder, then download proprietary driver modules to it.
 * See also Required_packages
 * 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) Add layer meta-rcar
 * 2) Start the build
 * 3) 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--.tar.bz2 is the rootfs, modules-.tgz are kernel modules.
 * 1) You can now proceed with running Yocto images

DTS overlay
Since the meta-rcar supports the DTS overlays then you can test option periferals without recompilation. Ex) => ext4load mmc 0 0x48080000 /boot/Image; ext4load mmc 0 0x48000000 /boot/r8a77951-ulcb-kf.dtb Ex1) test CN11 => ext4load mmc 0 0x48040000 /boot/ulcb-kf-cn11.dtbo Ex2) test SD card(CN47) instead WiFi => ext4load mmc 0 0x48040000 /boot/ulcb-kf-sd3.dtbo Ex3) test Most => ext4load mmc 0 0x48040000 /boot/ulcb-kf-most.dtbo => fdt addr 0x48000000; fdt resize 8192; fdt apply 0x48040000 => booti 0x48080000 - 0x48000000
