[http://git.yoctoproject.org/cgit/cgit.cgi/poky/tag/?id=yocto-1.6.1 Poky-1.6.1] is supported. Specific commit of meta-openembedded is required.
+
Two versions of Yocto are supported - 1.6.1 and 2.0. Yocto 1.6.1 builds a BSP based on Linux kernel 3.10 and Yocto 2.0 builds a BSP based on kernel 4.4. This page contains the instructions for building Yocto 1.6.1. <br/>
 +
<br/>[http://elinux.org/RZ-G/Boards/Yocto_2.0 Click here for instructions on building Yocto 2.0].
 +
 
 +
<br/>[http://git.yoctoproject.org/cgit/cgit.cgi/poky/tag/?id=yocto-1.6.1 Yocto-1.6.1 (Daisy)] is compatible with various Linux distributions - Ubuntu 12, 13 and 14, Debian 7, Fedora 19 and 20 and others. For a complete list of the supported distributions see the [http://www.yoctoproject.org/docs/1.6.1/ref-manual/ref-manual.html#detailed-supported-distros Supported Linux Distributions] section of the Yocto 1.6.1 Reference Manual. Please use one of the distributions on that list, e.g. Ubuntu 14.04 LTS.
 +
 
 +
== Quick steps ==
 +
To get started, pull the https://github.com/renesas-rz/meta-renesas tree.
 +
 
 +
Update bblayers.conf by adding the the meta-renesas and meta-rzg1 layers. e.g.:
 +
 
 +
        BBLAYERS ?= " \
 +
                <path to layer>/poky/meta \
 +
                <path to layer>/poky/meta-yocto \
 +
                <path to layer>/poky/meta-yocto-bsp \
 +
                <path to layer>/meta-renesas \
 +
                <path to layer>/meta-renesas/meta-rzg1 \
 +
        "
 +
 
 +
Specify the associated machine in local.conf:
 +
 
 +
        MACHINE ?= "<supported board name>" (skrzg1m skrzg1e)
 +
 
 +
Setup be build environment using the 'oe-init-build-env' script in Poky:
 +
 
 +
        $ source poky/oe-init-build-env
 +
 
 +
Build the target file system image using bitbake:
 +
 
 +
        $ bitbake core-image-minimal
 +

== Exporting Toolchains ==
 +
Before exporting a toolchain/SDK, the steps in [[#Building the BSP for the Renesas RZ/G1 Starter Kit Boards|Building the BSP for the Renesas RZ/G1 Starter Kit Boards]] must be executed (up to running bitbake) to prepare the proper recipe environment. There is no need to actually build the BSP, but if it is already built the $WORK/build directory can be reused.
 +
<ol>
 +
<li>Configure the target architecture for the SDK. Edit $WORK/build/conf/local.conf and make sure the SDKMACHINE variable is correctly set:
 +
<pre>
 +
SDKMACHINE ?= "i686" (or " x86_64")
 +
</pre>
 +
</li>
 +
<li>Build the SDK using bitbake:
 +
<pre>
 +
cd $WORK/build
 +
bitbake core-image-weston-sdk -c populate_sdk
 +
</pre>
 +
The SDK is distributed as a single script file that is located in $WORK/build/tmp/deploy/sdk/poky-eglibc-x86_64(or i686)-core-image-weston-sdk-cortexa7hf-vfp-neon-toolchain-1.6.1.sh
 +
</li>
 +
<li>Install the toolchain. Copy the toolchain script to the host build machine and run it:
 +
<pre>
 +
sudo ./poky-eglibc-i686-core-image-weston-sdk-cortexa7hf-vfp-neon-toolchain-1.6.1.sh
 +
</pre>
 +
By default the toolchain is installed under /opt/poky/poky1.6.1
 +
</li>
 +
<li>Prepare the environment by sourcing the proper script. This step needs to be executed in a new terminal window, not the one used to build the SDK:
 +
<pre>
 +
source /opt/poky/1.6.1/environment-setup-cortexa7hf-vfp-neon-poky-linux-gnueabi
 +
</pre>
 +
If building kernel, drivers or u-boot, disable the LDFLAGS variable by running:
 +
<pre>
 +
export LDFLAGS=””
 +
</pre>
 +
</li>
 +
<li>The SDK is ready to use. E.g. for make-based projects you can run 'make', or you can invoke gcc directly:
 +
<pre>
 +
$CC (Your source code).c
 
</pre>
 
</pre>
 
</li>
 
</li>

This page contains information on building and running Yocto on the Renesas RZ/G1E and Renesas RZ/G1M Starter Kit boards.

Yocto versions and supported Linux distributions

Two versions of Yocto are supported - 1.6.1 and 2.0. Yocto 1.6.1 builds a BSP based on Linux kernel 3.10 and Yocto 2.0 builds a BSP based on kernel 4.4. This page contains the instructions for building Yocto 1.6.1.

Click here for instructions on building Yocto 2.0.


Yocto-1.6.1 (Daisy) is compatible with various Linux distributions - Ubuntu 12, 13 and 14, Debian 7, Fedora 19 and 20 and others. For a complete list of the supported distributions see the Supported Linux Distributions section of the Yocto 1.6.1 Reference Manual. Please use one of the distributions on that list, e.g. Ubuntu 14.04 LTS.

Quick steps

To get started, pull the https://github.com/renesas-rz/meta-renesas tree.

Update bblayers.conf by adding the the meta-renesas and meta-rzg1 layers. e.g.: 

       BBLAYERS ?= " \
               <path to layer>/poky/meta \
               <path to layer>/poky/meta-yocto \
               <path to layer>/poky/meta-yocto-bsp \
               <path to layer>/meta-renesas \
               <path to layer>/meta-renesas/meta-rzg1 \
       "

Specify the associated machine in local.conf: 

       MACHINE ?= "<supported board name>" (skrzg1m skrzg1e)

Setup be build environment using the 'oe-init-build-env' script in Poky: 

       $ source poky/oe-init-build-env

Build the target file system image using bitbake: 

       $ bitbake core-image-minimal


Preliminary steps

  1. Download proprietary graphics and multimedia libraries and drivers from Renesas. Evaluation version of the libraries is available at
    https://www.renesas.com/en-us/software/D3016958.html
    and the drivers can be downloaded from
    https://www.renesas.com/en-us/software/D3017598.html
    The Graphic packages are required for X11 and Wayland. Multimedia drivers are optional.

  2. Install required packages:
    Ubuntu and Debian 
    sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
     build-essential chrpath socat libsdl1.2-dev xterm

    Fedora 

    sudo yum install gawk make wget tar bzip2 gzip python unzip perl patch \
     diffutils diffstat git cpp gcc gcc-c++ glibc-devel texinfo chrpath \
     ccache perl-Data-Dumper perl-Text-ParseWords perl-Thread-Queue socat \
     SDL-devel xterm

    Refer to Yocto Project Quick Start for more information.

Building the BSP for the Renesas RZ/G1 Starter Kit Boards

  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. 
    export WORK=<path-to-your-build-directory>
mkdir $WORK
cd $WORK
  2. Clone the 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
  3. Switch to proper branches/commits: 
    cd $WORK/poky
git checkout -b tmp yocto-1.6.1

cd $WORK/meta-openembedded
git checkout -b tmp dca466c074c9a35bc0133e7e0d65cca0731e2acf

cd $WORK/meta-linaro
git checkout -b tmp 8a0601723c06fdb75e62aa0f0cf15fc9d7d90167

    Other versions are not tested for compatibility.

  4. Edit the file $WORK/meta-linaro/meta-linaro-toolchain/recipes-devtools/gcc/gcc-linaro-4.8.inc to adjust the source URL for the Linaro toolchain (add 'archive' right after the base url): 
    -SRC_URI = "https://releases.linaro.org/${MMYY}/components/toolchain/gcc-linaro/${BASEPV}/gcc-${PV}-${RELEASE}.tar.xz \
+SRC_URI = "https://releases.linaro.org/archive/${MMYY}/components/toolchain/gcc-linaro/${BASEPV}/gcc-${PV}-${RELEASE}.tar.xz \
  5. Clone the Renesas BSP layer: 
    cd $WORK
git clone https://github.com/renesas-rz/meta-renesas
  6. Switch to a known tag: 
    cd $WORK/meta-renesas
git checkout -b tmp certified-linux-v1.0.0
  7. Download the proprietary libraries from
    https://www.renesas.com/en-us/software/D3016958.html
    and related kernel drivers from https://www.renesas.com/en-us/software/D3017598.html
  8. Create an install folder for the proprietary libraries: 
    cd $WORK
mkdir proprietary

    Copy the downloaded proprietary libraries into this new folder, e.g.: 

    cp ~/Downloads/RZG_Series_Evaluation_Software_Package* $WORK/proprietary
  9. Unzip the proprietary libraries, e.g.: 
    cd $WORK/proprietary
unzip RZG_Series_Evaluation_Software_Package_for_Linux-20151202.tar.gz.zip
unzip RZG_Series_Evaluation_Software_Package_of_Linux_Drivers-20151202.tar.gz.zip

    You should see the following files: 

    $ ls -l $WORK/proprietary
total 4.3M
-rw-rw-r-- 1 builduser builduser 3.1M Dec 06 10:25 RZG_Series_Evaluation_Software_Package_for_Linux-20151202.tar.gz
-rw-rw-r-- 1 builduser builduser 1.2M Dec 06 10:25 RZG_Series_Evaluation_Software_Package_of_Linux_Drivers-20151202.tar.gz
  10. Populate the meta-renesas layer with graphics and multimedia drivers: 
    cd $WORK/meta-renesas/meta-rzg1
./copy_gfx_software_<board>.sh ../../proprietary
./copy_mm_software_lcb.sh ../../proprietary
  11. Setup build environment: 
    cd $WORK
source poky/oe-init-build-env
  12. Prepare default configuration files: 
    cd $WORK/build
cp ../meta-renesas/meta-rzg1/templates/<board>/bblayers.conf ./conf

    For weston/wayland: 

    cp ../meta-renesas/meta-rzg1/templates/<board>/local-wayland.conf ./conf/local.conf

    For X11: 

    cp ../meta-renesas/meta-rzg1/templates/<board>/local-x11.conf ./conf/local.conf

    Edit local.conf to enable/disable graphics and multimedia proprietary drivers support. The H264 encoder library is not enabled by default, in order to enable it uncomment the following line:
    DISTRO_FEATURES_append = " h264avcenc_lib"

  13. Start the build
    For weston/wayland: 
    bitbake core-image-weston

    For X11: 

    bitbake core-image-x11

    Building the 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.

  14. Bitbake has generated all the necessary files in ./tmp/deploy/images directory.
    You can verify its content: 
    $ ls -lh `find ./tmp/deploy/images/skrzg1e/ -maxdepth 1 -type l -print`

    uImage is the kernel image, uImage-r8a7745-skrzg1e.dtb is the device tree file, uImage+dtb is the combined kernel and device tree image, core-image-weston-skrzg1e.tar.bz2 is the rootfs, modules-skrzg1e.tgz are the kernel modules.

  15. You can now boot the RZ/G1E or RZ/G1M Starter Kit boards over TFTP and NFS

Running the Yocto image

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 servers:

  1. Setup a TFTP server:
    Ubuntu and Debian
    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 uImage and the dtb file from $WORK/build/tmp/deploy/images/<board>/ to the TFTP server root.
    Note 1: The instructions here use separate kernel and dtb files. See section Loading kernel and rootfs from microSD card for using the combined kernel+dtb image
    Note 2: On Ubuntu/Debian the TFTP server root may be under /srv/tftp instead of /var/lib/tftpboot

    RZ/G1E Starter Kit board: 
    cp $WORK/build/tmp/deploy/images/skrzg1e/uImage /var/lib/tftpboot/
cp $WORK/build/tmp/deploy/images/skrzg1e/uImage-r8a7745-skrzg1e.dtb /var/lib/tftpboot/

    RZ/G1M Starter Kit board: 

    cp $WORK/build/tmp/deploy/images/skrzg1m/uImage /var/lib/tftpboot/
cp $WORK/build/tmp/deploy/images/skrzg1m/uImage-r8a7743-skrzg1m.dtb /var/lib/tftpboot/
  3. Verify that TFTP server is working. 
    $ tftp localhost 
tftp> get uImage
Received 3291623 bytes in 0.3 seconds

    If you get 'permission denied' errors, modify the file permissions to allow read access to everyone: 

    $ sudo chmod 444 /var/lib/tftpboot/uImage
  4. Setup NFS server
    Ubuntu and Debian
    1. Install necessary packages: 
      sudo apt-get install nfs-kernel-server nfs-common
    2. Start NFS server. This might fail because of no exports, in that case just run the command again after adding the exports: 
      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|x11|sato|directfb
MACHINE=skrzg1e|skrzg1m
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/skrzg1e	*(rw,no_subtree_check,sync,no_root_squash,no_all_squash)
/nfs/skrzg1m	*(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. 
    $ showmount -e localhost
Export list for localhost:
/nfs/skrzg1e *
/nfs/skrzg1m *
  7. Boot into U-Boot command prompt
    For the RZ/G1E Starter Kit board
    1. Make sure SW9 is on pin 1 side.
      Switch pin layout
    2. Connect to serial console over microUSB using minicom or picocom.
    3. Switch the board on or reset it. Press any key to stop U-Boot automatic countdown and go to U-Boot prompt.

    Refer to RZ/G1E Starter Kit board page for more information.
    For the RZ/G1M Starter Kit board

    1. TBD
  8. Configure Ethernet, TFTP, and kernel command line in U-Boot: 
    setenv ipaddr <board-ip>
setenv serverip <your-computer-ip>
setenv bootcmd 'tftp 0x40007fc0 uImage; tftp 0x40f00000 uImage-r8a7745-skrzg1e.dtb; bootm 0x40007fc0 - 0x40f00000'
setenv bootargs 'console=ttySC10,38400 ignore_loglevel rw root=/dev/nfs nfsroot=<your-computer-ip>:<nfs-path>,nfsvers=3 ip=<board-ip>:<your-computer-ip>::255.255.255.0:skrzg1e vmalloc=384M'
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 0x40007fc0 uImage; tftp 0x40f00000 uImage-r8a7745-skrzg1e.dtb; bootm 0x40007fc0 - 0x40f00000'
setenv bootargs 'console=ttySC10,38400 ignore_loglevel rw root=/dev/nfs nfsroot=192.168.1.2:/nfs/skrzg1e,nfsvers=3 ip=192.168.1.3:192.168.1.2::255.255.255.0:skrzg1e vmalloc=384M'
saveenv

    The last command writes the configuration to SPI flash. 

    => saveenv                                                                                                                                  
Saving Environment to SPI Flash...                                                                                                          
SF: Detected S25FL512S with page size 256 KiB, total 64 MiB                                                                                 
Erasing SPI flash...Writing to SPI flash...done

    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:

Loading kernel and rootfs from microSD card

Both kernel and root FS can be loaded from a microSD card. The approach requires only a console cable. No Ethernet connection is needed.

  1. Find a reliable microSD card with an adapter to fit your computer. 4 GB should be enough for the task.
  2. Plug the SD card into you computer. Locate the proper device for it, typically /dev/mmcblk0. Use 
    dmesg | tail

    to print latest messages if in doubt.
    WARNING! Be very careful. Do not select you root partition or any other device with important information. It may be destroyed!
    Double-check that device name is correct by mounting and examining it's content.

  3. Make sure the SD card doesn't contain any important files.
    WARNING! Next step may erase the SD card completely. All files my be lost.
  4. Format the card with one partition with EXT3 file system.
    TBD Update this page with a script which formats the card
  5. Copy root fs to the sd card: 
    SD=<path-to-your-device-partition>
SD_ROOT=/tmp/sd-tool
sudo umount "${SD}"
sudo mkdir -p "${SD_ROOT}"
sudo mount "${SD}" "${SD_ROOT}"
sudo rm -rf "${SD_ROOT}"/*
sudo cp "${BUILDDIR}/tmp/deploy/images/${MACHINE}/uImage+dtb" "${SD_ROOT}/boot/"
sudo tar -xjf "${BUILDDIR}/tmp/deploy/images/${MACHINE}/core-image-${IMAGE}-${MACHINE}.tar.bz2" -C "${SD_ROOT}"
sudo umount "${SD}"
  6. Insert the SD card into microSD slot on the board.
  7. Boot the board into U-Boot command prompt. Refer to section Boot into U-Boot command prompt


  8. Configure kernel command line in U-Boot:
    setenv bootcmd 'ext4load mmc 1:1 0x40007fc0 /boot/uImage+dtb; bootm 0x40007fc0'
setenv bootargs 'console=ttySC10,38400 ignore_loglevel rw rootfstype=ext3 root=/dev/mmcblk0p1 rootwait vmalloc=384M'
saveenv

    The last command writes the configuration to SPI flash. 

    => saveenv

Multiboot

U-Boot allows multiboot configurations. U-Boot can try different boot commands one by one until it finds the first working command. Use command line interface to configure u-boot. Dual source (MMC and NFS) boot configuration for the RZ/G1E Starter Kit board: 

setenv mkBootcmdMMC 'setenv bootcmd ext4load mmc 1:1 0x40007fc0 /boot/uImage+dtb\; bootm 0x40007fc0'
setenv mkBootargsMMC 'setenv bootargs console=ttySC10,38400 ignore_loglevel rw rootfstype=ext3 root=/dev/mmcblk0p1 rootwait vmalloc=384M'
setenv mkBootcmdTFTP 'setenv bootcmd tftp 0x40007fc0 uImage+dtb\; bootm 0x40007fc0'
setenv mkBootargsNFS 'setenv bootargs console=ttySC10,38400 ignore_loglevel rw root=/dev/nfs nfsroot=192.168.1.27:/nfs/skrzg1e,nfsvers=3 ip=192.168.1.107:192.168.1.27::255.255.255.0:skrzg1e vmalloc=384M'
setenv bootMMC 'run mkBootargsMMC; run mkBootcmdMMC; run bootcmd' 
setenv bootNET 'run mkBootargsNFS; run mkBootcmdTFTP; run bootcmd'
setenv bootcmd 'run bootMMC; run bootNET'

For the RZ/G1M Starter kit board mkBootcmdMMC, mkBootargsMMC, mkBootcmdTFTP and mkBootargsNFS should be changed to use the correct names.

Building QT

This section describes building Qt 5 for Renesas RZ-G boards. Both Qt 5.5 and 5.6 are supported

  1. Clone the meta-qt5 layer: 
    cd $WORK
git clone https://github.com/meta-qt5/meta-qt5.git
  2. Switch to the proper branch/commit.
    For Qt 5.6: 
    cd $WORK/meta-qt5
git checkout -b tmp c1b0c9f546289b1592d7a895640de103723a0305

    For Qt 5.5: 

    cd $WORK/meta-qt5
git checkout -b tmp 51b4620392aa9041d8512549bfa554bea368c5ea
  3. Cherry-pick a couple of poky patches to add contains_any: 
    cd $WORK/poky
git cherry-pick 17daa2ba6280304771c5fe52b94eb56f0c087490
git cherry-pick 8e0c54cd0e82ffe120f84f495101cd29e6fd06bf
  4. Qt 5.6 only: If building Qt 5.6, cherry pick a couple of additional poky commits: 
    cd $WORK/poky
git cherry-pick 1139cc4eef305fc14bc5db19a5f8729e7b3bf27a 
git cherry-pick 111af1d9138e7208200e48861be8f144a280b10e
  5. Qt 5.5 only: If building Qt 5.5, checkout the matching meta-renesas revision: 
    cd $WORK/meta-renesas
git checkout -b tmp 00649ea7ce956bd05dd3ed55fda8c66187a60236
  6. Add meta-qt5 and meta-rubby to bblayers.conf: 
      ${TOPDIR}/../meta-qt5 \
  ${TOPDIR}/../meta-openembedded/meta-ruby \
  7. Create your own configuration for Qt 5 by add the packages that you need to IMAGE_INSTALL: 
    IMAGE_INSTALL_append := qtbase ...

Building the Renesas demos

This section describes building the demos for Renesas RZ-G boards.

  1. Clone the meta-rzg-demos layer: 
    cd $WORK
git clone https://github.com/renesas-rz/meta-rzg-demos
  2. Checkout the proper meta-rzg-demos revision.
    For Qt 5.6: 
    cd $WORK/meta-rzg-demos
git checkout -b tmp certified-linux-v1.0.0

    For Qt 5.5: 

    cd $WORK/meta-rzg-demos
git checkout -b tmp 48b87fa9cb31c197e83fc643725402bf67fac8d0
  3. Copy the configuration files for the desired demo image. There are currently three images that can be built - 'hmi-demo', 'qt-hmi-demo' and 'doorphone'. 
    cd $WORK/build
cp ../meta-rzg-demos/meta-rzg1/<demo_folder>/template/<board>/bblayers.conf ./conf
cp ../meta-rzg-demos/meta-rzg1/<demo_folder>/template/<board>/local.conf ./conf

    4. When building the 'doorphone' demo from the 'certified-linux-v1.0.0' tag, there are a couple of manual steps that need to be done:
    1. Edit the file $WORK/meta-rzg-demos/meta-rzg1/common/recipes-qt/qt/qtbase_git.bbappend and uncomment the lines that apply the 'Disable DirectFB' patch: 

    -#SRC_URI_append += " \
-#	file://0001-Disable-DirectFB-automatic-detection-and-mark-it-dep.patch \
-#"
+SRC_URI_append += " \
+	file://0001-Disable-DirectFB-automatic-detection-and-mark-it-dep.patch \
+"

    2. Edit the file $WORK/build/conf/local.conf and enable the H264 encoder by uncommenting the following line:
    DISTRO_FEATURES_append = " h264avcenc_lib"

  4. Build core-image-weston: 
    bitbake core-image-weston

Exporting Toolchains

Before exporting a toolchain/SDK, the steps in Building the BSP for the Renesas RZ/G1 Starter Kit Boards must be executed (up to running bitbake) to prepare the proper recipe environment. There is no need to actually build the BSP, but if it is already built the $WORK/build directory can be reused.

  1. Configure the target architecture for the SDK. Edit $WORK/build/conf/local.conf and make sure the SDKMACHINE variable is correctly set: 
    SDKMACHINE ?= "i686" (or " x86_64")
  2. Build the SDK using bitbake: 
    cd $WORK/build
bitbake core-image-weston-sdk -c populate_sdk

    The SDK is distributed as a single script file that is located in $WORK/build/tmp/deploy/sdk/poky-eglibc-x86_64(or i686)-core-image-weston-sdk-cortexa7hf-vfp-neon-toolchain-1.6.1.sh

  3. Install the toolchain. Copy the toolchain script to the host build machine and run it: 
    sudo ./poky-eglibc-i686-core-image-weston-sdk-cortexa7hf-vfp-neon-toolchain-1.6.1.sh

    By default the toolchain is installed under /opt/poky/poky1.6.1

  4. Prepare the environment by sourcing the proper script. This step needs to be executed in a new terminal window, not the one used to build the SDK: 
    source /opt/poky/1.6.1/environment-setup-cortexa7hf-vfp-neon-poky-linux-gnueabi

    If building kernel, drivers or u-boot, disable the LDFLAGS variable by running: 

    export LDFLAGS=””
  5. The SDK is ready to use. E.g. for make-based projects you can run 'make', or you can invoke gcc directly: 
    $CC (Your source code).c
