== Build SDK ==
 +
* After building BSP you may build SDK:
 +
*: <syntaxhighlight lang="text">bitbake rcar-image-gateway -c populate_sdk</syntaxhighlight>
 +
* After build finished the SDK installation script may be found in following path:
 +
*: <syntaxhighlight lang="text">tmp/deploy/sdk/poky-glibc-x86_64-rcarimage-gateway-aarch64-spider-toolchain-3.1.11.sh</syntaxhighlight>
 +
* Install SDK by run the following command and follow instructions on the screen:
 +
*: <syntaxhighlight lang="text">sudo ./poky-glibc-x86_64-rcar-image-gateway-aarch64-spider-toolchain-3.1.11.sh</syntaxhighlight>

=== Preparing SD card ===
 
=== Preparing SD card ===
 +
<span style="color:#ff0000">'''WARNING!''' These steps will erase the SD card completely. In short, all files will be lost.</span><br/>
 +
Follow these steps on the host machine:
 +
# Partion your SD card to set 1 partition and ID=83 (Linux)
 +
#: Make sure the SD card doesn't contain any important files.
 +
#: <syntaxhighlight lang="bash">
 +
$ fdisk /dev/mmcblk0
 +
-> d
 +
-> n
 +
-> p
 +
-> 1
 +
-> t
 +
-> 83
 +
</syntaxhighlight>
 +
# Format this partition to ext4
 +
#: <syntaxhighlight lang="bash">
 +
$ mkfs.ext4 /dev/mmcblk0p1
 +
</syntaxhighlight>
 +
# Mount this partition on your host to any directory and upack the rcar-image-gateway-s4sk-proto.tar.bz2 into mounted folder.<br/>
 +
#: <syntaxhighlight lang="bash">
 +
$ mount /dev/mmcblk0p1 /mnt
 +
$ cd <your_yocto_build_directory>
 +
$ tar xfj build/tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.tar.bz2  -C /mnt
 +
</syntaxhighlight>
 +
#: NOTE: probably you need to be a root user, hence use "sudo"
 +
=== Configure U-Boot to boot from SD card ===
 +
* Proper U-Boot command to boot from SD:
 +
*: <syntaxhighlight lang="text">
 +
# setenv bootargs 'console=ttySC0,921600 rw root=/dev/mmcblk0p1 rootwait cma=560M'
 +
# ext4load mmc 0:1 0x48080000 /boot/Image

# ext4load mmc 0:1 0x48000000 /boot/r8a779f0-s4sk-prototype.dtb

# booti 0x48080000 - 0x48000000

    Software Revision
    Yocto Project 3.1.11
    aarch64-poky-linux-gcc (GCC) 9.3
    Kernel Ver 5.10.41
    Userland 64/32bit 64
    U-Boot 2020.10
    Renesas Yocto BSP v5.18.0 (R-Car SDK v3.9.0)

    Host PC

    Ubuntu 20.04 LTS (64bit) is recommended as OS. 32bit version is not supported.

    Supported BSP

    • Linux (this page)
    • Xen (here)

    How to build

    Installation of required tools and libraries

    Ubuntu is used as Linux Host PC since Yocto Project Quick Start specifies Ubuntu as one of the distributions. You need to install the required packages as follows. 

    sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat cpio python3 python3-pip python3-pexpect \
xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa \
libsdl1.2-dev pylint3 xterm libarchive-zip-perl

    Build script

    1. Build script(build.sh)

    Manual steps

    2022/12/27 updated

    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 https://github.com/renesas-rcar/meta-renesas
    3. Switch to proper branches/commits 
      cd $WORK/poky
git checkout -b tmp 74b22db6879b388d700f61e08cb3f239cf940d18
cd $WORK/meta-openembedded
git checkout -b tmp 814eec96c2a29172da57a425a3609f8b6fcc6afe
cd $WORK/meta-renesas
git checkout -b tmp a634d930d30af39eec68c9fc82ce113c74775c25
    4. Setup build environment 
      cd $WORK
source poky/oe-init-build-env $WORK/build
    5. Prepare default configuration files. 
      cp $WORK/meta-renesas/meta-rcar-gateway/docs/sample/conf/s4sk-proto/poky-gcc/bsp/*.conf conf/ ./conf/
cd $WORK/build
    6. Start the build 
      bitbake rcar-image-gateway
    7. 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 4956 tasks of which 5 didn't need to be rerun and all succeeded.
      and the command prompt should return.
    8. Bitbake has generated all the necessary files in ./tmp/deploy/images directory.
      You can verify its content: 
      $ ls -1 `find ./tmp/deploy/images/s4sk-proto/  -maxdepth 1 -type l -print`
./tmp/deploy/images/s4sk-proto/Image
./tmp/deploy/images/s4sk-proto/Image-s4sk-proto.bin

      Image is a Kernel image, r8a779f0-s4sk-prototype.dtb is a blob file, rcar-image-gateway-s4sk-proto.tar.bz2 is the rootfs, modules-s4sk-proto.tgz is kernel modules.

    Build SDK

    • After building BSP you may build SDK: 
      bitbake rcar-image-gateway -c populate_sdk
    • After build finished the SDK installation script may be found in following path: 
      tmp/deploy/sdk/poky-glibc-x86_64-rcarimage-gateway-aarch64-spider-toolchain-3.1.11.sh
    • Install SDK by run the following command and follow instructions on the screen: 
      sudo ./poky-glibc-x86_64-rcar-image-gateway-aarch64-spider-toolchain-3.1.11.sh

    Note: Please see the Known issues & Restrictions chapter.

    How to boot

    Loading kernel and rootfs via SD card

    This section describes steps that are necessary for preparing and booting from SD card.

    Preparing SD card

    WARNING! These steps will erase the SD card completely. In short, all files will be lost.
    Follow these steps on the host machine:

    1. Partion your SD card to set 1 partition and ID=83 (Linux)
      Make sure the SD card doesn't contain any important files.
      $ fdisk /dev/mmcblk0
-> d
-> n
-> p
-> 1
-> t
-> 83
    2. Format this partition to ext4 
      $ mkfs.ext4 /dev/mmcblk0p1
    3. Mount this partition on your host to any directory and upack the rcar-image-gateway-s4sk-proto.tar.bz2 into mounted folder.
      $ mount /dev/mmcblk0p1 /mnt
$ cd <your_yocto_build_directory>
$ tar xfj build/tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.tar.bz2  -C /mnt
      NOTE: probably you need to be a root user, hence use "sudo"

    Configure U-Boot to boot from SD card

    • Proper U-Boot command to boot from SD: 
      # setenv bootargs 'console=ttySC0,921600 rw root=/dev/mmcblk0p1 rootwait cma=560M'
# ext4load mmc 0:1 0x48080000 /boot/Image
# ext4load mmc 0:1 0x48000000 /boot/r8a779f0-s4sk-prototype.dtb
# booti 0x48080000 - 0x48000000
    • Example of U-Boot environment variables: 
      baudrate=921600
bootargs=root=console=ttySC0,921600 rw root=/dev/mmcblk0p1 rootwait cma=560M
bootcmd=ext4load mmc 0:1 0x48080000 /boot/Image; ext4load mmc 0:1 0x48000000 /boot/r8a779f0-s4sk-prototype.dtb; booti 0x48080000 - 0x48000000
bootdelay=2
bootm_size=0x10000000
fdtcontroladdr=bbf45160
loadaddr=0x58000000
platform=r8a779f0
