    Building the BSP for Renesas H3 Starter Kit, M3 Starter Kit

    NOTE: to have ADAS View and HAD Solution kits supported follow instructions: R-Car Yocto Gen3 ADAS

    Build using script

    This example is for H3ULCB board.
    If you use other board, you need to modify the script.

    1. Directory Structure
      |--build.sh
      `--proprietary
         |--R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-20190722.zip
         `--R-Car_Gen3_Series_Evaluation_Software_Package_of_Linux_Drivers-20190722.zip
      
    2. Build script(build.sh)
      #!/bin/bash
      
      #Set the target board
      TARGET_BOARD=h3ulcb
      #TARGET_BOARD=m3ulcb
      
      # Create a directory and switch to it
      mkdir $TARGET_BOARD
      cd $TARGET_BOARD
      WORK=`pwd`
      echo $WORK
      
      # Clone basic Yocto layers in parallel
      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 &
      
      # Wait for all clone operations
      wait
      
      # Switch to proper branches/commits
      cd $WORK/poky
      git checkout -b tmp 7e7ee662f5dea4d090293045f7498093322802cc
      cd $WORK/meta-openembedded
      git checkout -b tmp 352531015014d1957d6444d114f4451e241c4d23
      cd $WORK/meta-linaro
      git checkout -b tmp 75dfb67bbb14a70cd47afda9726e2e1c76731885
      cd $WORK/meta-renesas
      git checkout -b tmp 70d47c56f04a7ee78597770b88de68a59c56a4aa
      
      # Populate meta-renesas with proprietary software packages
      cd $WORK/meta-renesas
      sh meta-rcar-gen3/docs/sample/copyscript/copy_evaproprietary_softwares.sh -f $WORK/../proprietary
      
      cd $WORK
      source poky/oe-init-build-env $WORK/build
      
      #cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/${TARGET_BOARD}/poky-gcc/bsp/*.conf ./conf/.
      #cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/${TARGET_BOARD}/poky-gcc/gfx-only/*.conf ./conf/.
      cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/${TARGET_BOARD}/poky-gcc/mmp/*.conf ./conf/
      
      cd $WORK/build
      cp conf/local-wayland.conf conf/local.conf
      echo 'DISTRO_FEATURES_append = " use_eva_pkg"' >> $WORK/build/conf/local.conf
      
      bitbake core-image-weston
      
    3. build
      ./build.sh
      
      If the build completes successfully, all the necessary files are generated in a following directory:
      ./<target_board_name>/build/tmp/deploy/images/<target_board_name>
      

    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.
      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 git://git.linaro.org/openembedded/meta-linaro.git
      git clone git://github.com/renesas-rcar/meta-renesas
      
    3. Switch to proper branches/commits (2020/07/10 updated)
      cd $WORK/poky
      git checkout -b tmp 7e7ee662f5dea4d090293045f7498093322802cc
      cd $WORK/meta-openembedded
      git checkout -b tmp 352531015014d1957d6444d114f4451e241c4d23
      cd $WORK/meta-linaro
      git checkout -b tmp 75dfb67bbb14a70cd47afda9726e2e1c76731885
      cd $WORK/meta-renesas
      git checkout -b tmp 70d47c56f04a7ee78597770b88de68a59c56a4aa  # <= 2020/07/10 updated
      
      Another versions are not tested for compatibility.
      Legacy BSP instruction can be found here R-Car Yocto Gen3 legacy
    4. Download proprietary driver modules to $WORK/proprietary folder
      You should see the following files:
      $ ls -1 $WORK/proprietary/*.zip
      R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-20190722.zip
      R-Car_Gen3_Series_Evaluation_Software_Package_of_Linux_Drivers-20190722.zip
      
    5. 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
      
    6. Setup build environment
      cd $WORK
      source poky/oe-init-build-env $WORK/build
      
    7. Prepare default configuration files.
      cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/<h3ulcb|m3ulcb>/poky-gcc/mmp/*.conf ./conf/
      cd $WORK/build
      cp conf/local-wayland.conf conf/local.conf
      
    8. (Edit $WORK/build/conf/local.conf to enable/disable graphics and multimedia proprietary drivers support)
    9. Edit local.conf with evaluation packages requirements:
      DISTRO_FEATURES_append = " use_eva_pkg"
      
    10. Start the build
      bitbake core-image-weston
      
    11. 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.
    12. Bitbake has generated all the necessary files in ./tmp/deploy/images directory.
      You can verify its content:
      $ ls -1 `find ./tmp/deploy/images/h3ulcb/ -maxdepth 1 -type l -print`
      ./tmp/deploy/images/h3ulcb/core-image-weston-h3ulcb.cpio.gz
      ./tmp/deploy/images/h3ulcb/core-image-weston-h3ulcb.ext4
      ./tmp/deploy/images/h3ulcb/core-image-weston-h3ulcb.manifest
      ./tmp/deploy/images/h3ulcb/core-image-weston-h3ulcb.tar.bz2
      ./tmp/deploy/images/h3ulcb/Image
      ./tmp/deploy/images/h3ulcb/Image-h3ulcb.bin
      ./tmp/deploy/images/h3ulcb/Image-r8a7795-es1-h3ulcb.dtb
      ./tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb-4x2g.dtb
      ./tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb.dtb
      ./tmp/deploy/images/h3ulcb/modules-h3ulcb.tgz
      ./tmp/deploy/images/h3ulcb/u-boot.bin
      ./tmp/deploy/images/h3ulcb/u-boot-elf-h3ulcb.srec
      ./tmp/deploy/images/h3ulcb/u-boot-elf.srec
      ./tmp/deploy/images/h3ulcb/u-boot-h3ulcb.bin
      
      Image is a Kernel image, *.dtb is a blob file, core-image-weston-h3ulcb.tar.bz2 is the rootfs, modules-h3ulcb.tgz are kernel modules.
    13. You can now proceed with running Yocto images

    Build SDK

    • After building BSP you may build SDK:
      bitbake core-image-weston -c populate_sdk
      
    • After build finished the SDK installation script may be found in following path:
      tmp/deploy/sdk/poky-glibc-x86_64-core-image-weston-aarch64-toolchain-*.sh
      
    • Install SDK by run the following command and follow instructions on the screen:
      ./tmp/deploy/sdk/poky-glibc-x86_64-core-image-weston-aarch64-toolchain-*.sh
      
    • setup environment variables for each compilation on each Host PCs
      cd (Your working directory)
      source /opt/poky/2.4.3/environment-setup-aarch64-poky-linux
      export LDFLAGS=””
      ${CC} (Your source code).c …..
      

    Running Yocto images

    Linux kernel can be booted from microSD card or from TFTP. Root FS can be mounted from micro SD card or via NFS.

    Combination of board and dtb file

    Please refer to here .

    Loading kernel via TFTP and rootfs via NFS

    Follow these steps to setup working TFTP and NFS server:

    1. Setup a TFTP server.
      Ubuntu
      Install tftpd-hpa package along with tftp tools:
      sudo apt-get install tftp tftpd-hpa
      
      Fedora
      1. Install necessary packages:
        sudo yum install tftp-server tftp
        
        tftp-server is a part of xinetd. See Fedora manual for more information.
      2. Enable TFTP server:
        sudo vi /etc/xinetd.d/tftp
        
        Set
        disable = no
        
        Save file and exit.
      3. Start xinetd:
        sudo systemctl start xinetd.service
        sudo systemctl enable xinetd.service
        
    2. Copy Image and Image-r8a7795-h3ulcb.dtb (for ws2.0 silicon) and/or Image-r8a7795-h3ulcb-4x2g.dtb (for RTP0RC77951SKBX010SA03(DDR 8GiB)) and/or Image-r8a7795-es1-h3ulcb.dtb (for ws1.1) from $WORK/build/tmp/deploy/images/h3ulcb/ to TFTP server root.
      Ubuntu
      cp $WORK/build/tmp/deploy/images/h3ulcb/Image /srv/tftp/
      cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-es1-h3ulcb.dtb /srv/tftp/
      cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb.dtb /srv/tftp/
      cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb-4x2g.dtb /srv/tftp/
      
      Fedora
      cp $WORK/build/tmp/deploy/images/h3ulcb/Image /var/lib/tftpboot/
      cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-es1-h3ulcb.dtb /var/lib/tftpboot/
      cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb.dtb /var/lib/tftpboot/
      cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb-4x2g.dtb /var/lib/tftpboot/
      
      Which version is my H3SK board?
    3. Verify that TFTP server is working.
      tftp localhost -c get Image && ls Image
      
    4. Setup NFS server.
      Debian/Ubuntu
      1. Install necessary packages:
        sudo apt-get install nfs-kernel-server nfs-common
        
      2. Start NFS server:
        sudo /etc/init.d/nfs-kernel-server start
        
      Fedora
      1. Install necessary packages:
        • sudo yum install nfs-utils
          
      2. Enable and start nfs server:
        sudo systemctl enable rpcbind.service 
        sudo systemctl enable nfs-server.service 
        sudo systemctl enable nfs-lock.service 
        sudo systemctl enable nfs-idmap.service
        sudo systemctl start rpcbind.service 
        sudo systemctl start nfs-server.service 
        sudo systemctl start nfs-lock.service 
        sudo systemctl start nfs-idmap.service
        
    5. Export root FS to NFS. (Change IMAGE and MACHINE to fit your build).
      1. Unpack rootfs to a dedicated directory:
        IMAGE=weston
        MACHINE=h3ulcb|m3ulcb
        NFS_ROOT=/nfs/${MACHINE}
        sudo mkdir -p "${NFS_ROOT}"
        sudo rm -rf "${NFS_ROOT}"/*
        sudo tar -xjf "${WORK}/build/tmp/deploy/images/${MACHINE}/core-image-${IMAGE}-${MACHINE}-*.tar.bz2" -C "${NFS_ROOT}"
        sync
        
      2. Edit /etc/exports:
        sudo vi /etc/exports
        
        add
        /nfs/h3ulcb	*(rw,no_subtree_check,sync,no_root_squash,no_all_squash)
        /nfs/m3ulcb	*(rw,no_subtree_check,sync,no_root_squash,no_all_squash)
        
        Save the file and exit.
      3. Force NFS server to re-read /etc/exports
        sudo exportfs -a
        
    6. Verify that NFS is working.
      [builduser@buildmachine ~]$ showmount -e localhost
      Export list for localhost:
      /nfs/h3ulcb *
      /nfs/m3ulcb *
      
    7. Boot into U-Boot command prompt
      1. Connect to serial console over microUSB using minicom or picocom.
      2. Switch the board on or reset it. Press any key to stop U-Boot automatic countdown.
      Refer to H3SK board page, M3SK board page for more information.
    8. Configure Ethernet, TFTP, and kernel command line in U-Boot:
      setenv ipaddr <board-ip>
      setenv serverip <your-computer-ip>
      setenv bootcmd 'tftp 0x48080000 Image; tftp 0x48000000 Image-r8a7795-h3ulcb.dtb; booti 0x48080000 - 0x48000000'
      setenv bootargs 'ignore_loglevel rw root=/dev/nfs nfsroot=<your-computer-ip>:<nfs-path>,nfsvers=3 ip=<board-ip>:<your-computer-ip>::255.255.255.0:h3ulcb'
      saveenv
      
      Replace <board-ip> with the proper IP address for the board. Replace <your-computer-ip> with the IP address of your computer, where tftp and nfs servers are installed. Replace <nfs-path> with the exported path of the root FS.
      For example:
      setenv ipaddr 192.168.1.3
      setenv serverip 192.168.1.2
      setenv bootcmd 'tftp 0x48080000 Image; tftp 0x48000000 Image-r8a7795-h3ulcb.dtb; booti 0x48080000 - 0x48000000'
      setenv bootargs 'ignore_loglevel rw root=/dev/nfs nfsroot=192.168.1.2:/nfs/h3ulcb,nfsvers=3 ip=192.168.1.3:192.168.1.2::255.255.255.0:h3ulcb'
      saveenv
      
      You can also use
      dhcp
      
      command to obtain information from DHCP server.
      Note: You can always see the environment with printenv command. Refer to U-Boot manual for details.
    9. Verify the connection over Ethernet from U-Boot:
      ping <your-computer-ip>
      
      You should see:
      => ping 192.168.1.2

    Loading kernel and rootfs via eMMC/SD card

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

    Preparing eMMC/SD card

    In order to prepare you SD card, follow these instructions on 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.
      WARNING! These steps may erase the SD card completely. All files my be lost.
      $ fdisk /dev/mmcblk0
      -> d
      -> n
      -> p
      -> 1
      -> t
      -> 83
      
    2. Format this partition to ext3 (or ext4)
      $ mkfs.ext3 /dev/mmcblk0p1
      
    3. Mount this partition on your host to any directory and upack the core-image-weston-*.tar.bz2 into mounted folder. And Copy Image and Image-r8a7795-h3ulcb.dtb (for ws2.0 silicon) and/or Image-r8a7795-h3ulcb-4x2g.dtb (for RTP0RC77951SKBX010SA03(DDR 8GiB)) and/or Image-r8a7795-es1-h3ulcb.dtb (for ws1.1) from $WORK/build/tmp/deploy/images/h3ulcb/ to sd card /boot. In case of m3ulcb copy dtb from $WORK/build/tmp/deploy/images/m3ulcb/.
      $ mount /dev/mmcblk0p1 /mnt
      $ cd <your_yocto_build_directory>
      $ tar xfj  build/tmp/deploy/images/h3ulcb/core-image-weston-h3ulcb-*.rootfs.tar.bz2  -C /mnt
      $ cp $WORK/build/tmp/deploy/images/h3ulcb/XXXX.dtb /mnt/boot/
      
      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 'rw root=/dev/mmcblk1p1 rootwait'
      # ext2load mmc 0:1 0x48080000 /boot/Image
      # ext2load mmc 0:1 0x48000000 /boot/Image-r8a7795-h3ulcb.dtb
      # booti 0x48080000 - 0x48000000
      
      Note from user:
      When I created my image with mkfs.ext3, and booted with rootfstype=ext3, the kernel could not find mount the filesystem.
      The kernel boot gave an error message:
      "EXT4-fs (mmcblk1p1): couldn't mount as ext3 due to feature incompatibilities".
      I switched to 'rootfstype=ext4' in my bootargs, and the kernel booted OK.
    • Example of U-Boot environment variables:
      baudrate=115200
      bootargs_emmc=rw root=/dev/mmcblk0p1 rootwait
      bootargs_nfs=rw root=/dev/nfs rootwait ip=dhcp
      bootargs_sd0=rw root=/dev/mmcblk1p1 rootwait
      bootcmd=run bootcmd_sd0
      bootcmd_emmc=set bootargs ${bootargs_emmc};ext2load mmc 1:1 0x48080000 /boot/Image;ext2load mmc 1:1 0x48000000 /boot/${dtb};run booti_cmd
