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
./build.sh
- If the build completes successfully, all the necessary files are generated in a following directory:
./s4sk_proto/build/tmp/deploy/images/s4sk-proto/
Manual steps
2022/12/27 updated
- 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 https://github.com/renesas-rcar/meta-renesas
- 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
- Setup build environment
cd $WORK source poky/oe-init-build-env $WORK/build
- Prepare default configuration files.
cp $WORK/meta-renesas/meta-rcar-gateway/docs/sample/conf/s4sk-proto/poky-gcc/bsp/*.conf conf/ ./conf/ cd $WORK/build
- Start the build
bitbake rcar-image-gateway
- Building image can take up to a few hours depending on your host system performance.
After the build has been completed successfully, you should see the output similar to:NOTE: Tasks Summary: Attempted 4956 tasks of which 5 didn't need to be rerun and all succeeded.
- and the command prompt should return.
- Bitbake has generated all the necessary files in ./tmp/deploy/images directory.
You can verify its content:$ 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 ./tmp/deploy/images/s4sk-proto/modules-s4sk-proto.tgz ./tmp/deploy/images/s4sk-proto/r8a779f0-s4sk-prototype-s4sk-proto.dtb ./tmp/deploy/images/s4sk-proto/r8a779f0-s4sk-prototype.dtb ./tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.manifest ./tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.tar.bz2 ./tmp/deploy/images/s4sk-proto/rcar-image-gateway-s4sk-proto.testdata.json ./tmp/deploy/images/s4sk-proto/u-boot-elf-s4sk-proto.srec ./tmp/deploy/images/s4sk-proto/u-boot-elf.srec ./tmp/deploy/images/s4sk-proto/u-boot-initial-env ./tmp/deploy/images/s4sk-proto/u-boot-initial-env-s4sk-proto ./tmp/deploy/images/s4sk-proto/u-boot-s4sk-proto.bin ./tmp/deploy/images/s4sk-proto/u-boot.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.
In order to prepare you SD card, follow these instructions on 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.
$ fdisk /dev/mmcblk0 -> d -> n -> p -> 1 -> t -> 83
- Format this partition to ext4
$ mkfs.ext4 /dev/mmcblk0p1
- 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 stderr=serial@e6540000 stdin=serial@e6540000 stdout=serial@e6540000
