    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>

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 https://github.com/renesas-rcar/meta-renesas
  3. Switch to proper branches/commits 
    cd $WORK/poky
git checkout -b tmp 424296bf9bb4bae27febf91bce0118df09ce5fa1
cd $WORK/meta-openembedded
git checkout -b tmp f2d02cb71eaff8eb285a1997b30be52486c160ae
cd $WORK/meta-renesas
git checkout -b tmp fd8ab2bb1b5ca98483c6f4aecf09a85c4d6bc016
    Another versions are not tested for compatibility.
    Legacy BSP instruction can be found here R-Car Yocto Gen3 legacy
  4. Apply patch to update meta-rcar(patch file: File:Update-meta-rcar-for-Yv510-20210531.patch.zip) 
    cd ${WORK}
curl -sO https://elinux.org/images/6/6a/Update-meta-rcar-for-Yv510-20210531.patch.zip
unzip -qo Update-meta-rcar-for-Yv510-20210531.patch.zip
cd ${WORK}/meta-renesas
patch -N -p1 < ../Update-meta-rcar-for-Yv510-20210531.patch
  5. Create $WORK/../proprietary folder, then download proprietary driver modules to it.
    See also Required_packages

    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

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.

Loading kernel via TFTP and rootfs via NFS

Follow these steps to setup working TFTP and NFS server:

  1. Setup a TFTP server.
    Install tftpd-hpa package along with tftp tools:
    sudo apt-get install tftp tftpd-hpa
  2. Copy Image and XXXX.dtb from $WORK/build/tmp/deploy/images/<board_name>/ to TFTP server root. 
    cp $WORK/build/tmp/deploy/images/h3ulcb/Image /srv/tftp/
cp $WORK/build/tmp/deploy/images/h3ulcb/XXXX.dtb /srv/tftp/
    Which version is my H3SK board?
  3. Verify that TFTP server is working. 
    tftp localhost << EOS
    get Image
    quit
EOS
ls Image
  4. Setup NFS server.
    1. Install necessary packages: 
      sudo apt-get install nfs-kernel-server nfs-common
    2. Start NFS server: 
      sudo /etc/init.d/nfs-kernel-server start
  5. Export root FS to NFS. (Change IMAGE and MACHINE to fit your build).
    1. Unpack rootfs to a dedicated directory: 
      IMAGE=weston
MACHINE=h3ulcb|m3ulcb
NFS_ROOT=/nfs/${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 dtb <your-dtb-file-name>
setenv bootcmd 'tftp 0x48080000 <path_to_Image>/Image; tftp 0x48000000 <path_to_dtb>/${dtb}; booti 0x48080000 - 0x48000000'
setenv bootargs 'ignore_loglevel rw root=/dev/nfs nfsroot=<your-computer-ip>:<nfs-path>,nfsvers=3 ip=<board-ip>:<your-computer-ip>::255.255.255.0:h3ulcb'
saveenv
    Replace <board-ip> with the proper IP address for the board. Replace <your-computer-ip> with the IP address of your computer, where tftp and nfs servers are installed. Replace <nfs-path> with the exported path of the root FS.
    For example:
    setenv ipaddr 192.168.1.3
setenv serverip 192.168.1.2
setenv dtb r8a77951-ulcb.dtb
setenv bootcmd 'tftp 0x48080000 /Image; tftp 0x48000000 /${dtb}; booti 0x48080000 - 0x48000000'
setenv bootargs 'ignore_loglevel rw root=/dev/nfs nfsroot=${serverip}:/nfs/h3ulcb,nfsvers=3,tcp ip=${ipaddr}:${serverip}::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
Using ethernet@e6800000 device
host 192.168.1.2 is alive
  10. Reset the board by pushing reset button
    Refer to H3SK board page, M3SK board page for more information.

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

WARNING! These steps will erase the SD card completely. In short, all files will be lost.
There two methods to prepare SD card. so, please select one of them.

Manual steps

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.
    $ 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-*.tar.bz2 into mounted folder.
    And Copy Image and XXXX.dtb from $WORK/build/tmp/deploy/images/<board_name>/ to sd card /boot. 
    $ mount /dev/mmcblk0p1 /mnt
$ cd <your_yocto_build_directory>
$ IMAGE=weston
$ MACHINE=h3ulcb|m3ulcb
$ tar xfj  build/tmp/deploy/images/${MACHINE}/core-image-${IMAGE}-${MACHINE}-*.rootfs.tar.bz2  -C /mnt
$ cp $WORK/build/tmp/deploy/images/${MACHINE}/XXXX.dtb /mnt/boot/
    NOTE: probably you need to be a root user, hence use "sudo"
Using bmaptool

Install bmaptool by following command: 

sudo apt install bmap-tools

ex.) case of '/dev/sdb': 

sudo bmaptool copy ./core-image-weston-m3ulcb.wic.xz /dev/sdb
Note:
It requires to be located both *.wic.xz and *.wic.bmap in same directory.
It doesn't required to contain partition number(ex. /dev/sdb1, /dev/mmcblk0p1, and so on), /dev/mmcblk0 or /dev/sdb and so on are correct
Log: 
bash $ sudo bmaptool copy ./core-image-weston-m3ulcb.wic.xz /dev/XXXX
bmaptool: info: discovered bmap file './core-image-weston-m3ulcb.wic.bmap'
bmaptool: info: block map format version 2.0
bmaptool: info: 199184 blocks of size 4096 (778.1 MiB), mapped 102471 blocks (400.3 MiB or 51.4%)
bmaptool: info: copying image 'core-image-weston-m3ulcb.wic.xz' to block device '/dev/XXXX' using bmap file 'core-image-weston-m3ulcb.wic.bmap'
bmaptool: info: 100% copied
bmaptool: info: synchronizing '/dev/XXXX'
bmaptool: info: copying time: 1m 6.8s, copying speed 6.0 MiB/sec

Note:

/dev/XXXX is differnet by host PC environment.
It can be checked by using 'fdisk -l'.

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/XXXX.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: 
    bootargs_emmc=rw root=/dev/mmcblk0p1 rootwait
bootargs_nfs=rw root=/dev/nfs nfsroot=192.168.1.2:/nfs/h3ulcb,tcp,v3 rootwait ip=dhcp
