RZ-G/Boards/Yocto 2.0

This page contains information on building a Yocto 2.0 based Linux BSP for the Renesas RZ/G1E and  Renesas RZ/G1M Starter Kit boards. Click here for instructions on building a Yocto 1.6.1 BSP.

Supported Linux Host distributions
Yocto 2.0 (Jethro) is compatible with various Linux Host distributions - Ubuntu 14 and 15, Debian 7 and 8, Fedora 21 and 21 and others. For a complete list of the supported distributions see the Supported Linux Distributions section of the Yocto 2.0 Reference Manual. Please use one of the distributions on that list, e.g. Ubuntu 14.04 LTS.

Preliminary steps
  Install the required host packages: Ubuntu and Debian sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \ build-essential chrpath socat Fedora sudo dnf 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 \ findutils which Refer to Yocto Project Quick Start for more information. 

Download the proprietary Multimedia and Graphics evaluation libraries for RZ/G from Renesas: https://www.renesas.com/en-us/software/D6000548.html Download the related kernel drivers as well: https://www.renesas.com/en-us/software/D6000544.html You should have something like this: $ ls -1 RZG_Series_Evaluation_Software_Package_for_Linux-yyyymmdd.tar.gz.zip RZG_Series_Evaluation_Software_Package_of_Linux_Drivers-yyyymmdd.tar.gz.zip 

Download the helper scripts that will set up the build environment: 

 Unpack the script files: $ tar -xvf Rzg_scripts_yocto2.0.tar.gz rzg_bsp_setup_yocto2.0.sh rzg_demos_setup_yocto2.0.sh 



Setting up a new build directory
These steps need to be executed only once for a new build directory. For subsequent builds in the same directory skip this section and go straight to Building a BSP.  Create a build directory and switch to it: export WORK= mkdir $WORK cd $WORK 

Copy the downloaded multimedia and graphics zip files and the setup scripts to the build directory. You should have something like this: $ ls -1 rzg_bsp_setup_yocto2.0.sh rzg_demos_setup_yocto2.0.sh RZG_Series_Evaluation_Software_Package_for_Linux-yyyymmdd.tar.gz.zip RZG_Series_Evaluation_Software_Package_of_Linux_Drivers-yyyymmdd.tar.gz.zip 

 Execute the script rzg_bsp_setup_yocto2.0.sh: This will clone all necessary repositories, switch to the proper branches/commits, copy files as necessary, etc. ./rzg_bsp_setup_yocto2.0.sh </li> </ol>

Building a BSP
Warning! Yocto builds require a lot of disk space (up to 100 GB). Make sure you have got enough before starting the build.  Go to your build directory: export WORK=<path-to-your-build-directory> cd $WORK </li>

 Initialize the build environment: Note that this command is executed from the $WORK folder and it changes the current folder to $WORK\build source poky/oe-init-build-env </li>

 Copy the proper default configuration files (bblayers.conf and local.conf) depending on the target board. Currently two boards are supported - 'skrzg1m' (RZ/G1M Starter Kit) and 'skrzg1e' (RZ/G1E Starter Kit). Note: At this point the current folder should be $WORK/build cp ../meta-renesas/meta-rzg1/templates/ /bblayers.conf ./conf cp ../meta-renesas/meta-rzg1/templates/ /local.conf ./conf/local.conf You can edit the file local.conf, e.g. to enable/disable graphics and multimedia proprietary drivers support. </li>

 Start the build

bitbake core-image-weston 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. </li>

 Bitbake has generated all the necessary files in ./tmp/deploy/images directory. 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. </li>

 You can now boot the RZ/G1E or RZ/G1M Starter Kit boards over TFTP and NFS. You can also boot from microSD but note that the microSD slot is recognized as mmcblk1. </li> </ol>

Adding QT to the BSP
This section describes how to add Qt 5.6 to the base BSP built by the previous steps.  Clone the meta-qt5 layer: cd $WORK git clone https://github.com/meta-qt5/meta-qt5.git </li>

 Switch to the proper branch/commit. cd $WORK/meta-qt5 git checkout -b tmp c1b0c9f546289b1592d7a895640de103723a0305 </li>

 Add the build layers 'meta-qt5' and 'meta-rubby' to the file $WORK\build\conf\bblayers.conf: ${TOPDIR}/../meta-qt5 \ ${TOPDIR}/../meta-openembedded/meta-ruby \ </li> 

Add the desired Qt packages to the variable IMAGE_INSTALL. You can do that by modifying the file $WORK\build\conf\local.conf like this: IMAGE_INSTALL_append = " \   qtbase \    qtbase-fonts \    qtbase-plugins \     qtdeclarative \    qtdeclarative-qmlplugins \    qtdeclarative-plugins \    qtquick1 \    qtquick1-qmlplugins \     qtquick1-plugins \    qtwayland \    qtwayland-plugins \    qtbase-examples \ " </li> </ol>

Building the Renesas demos
This section describes how to build a couple of demo BSPs for the Renesas RZ/G boards. The demo BSPs extend the base BSP described in previous sections. Please make sure you have executed the preliminary steps as well as the steps in section Setting up a new build directory. There is no need to build the base BSP or to add the Qt framework manually, as the following steps will do that. 

 Execute the script rzg_demos_setup_yocto2.0.sh: This will clone all necessary repositories, switch to the proper branches/commits, etc. cd $WORK ./rzg_demos_setup_yocto2.0.sh </li>

 If this is a new terminal session, initialize the build environment: Note that this command is executed from the $WORK folder and it changes the current folder to $WORK\build source poky/oe-init-build-env </li>

<li> Copy the configuration files for the desired demo BSP and RZ/G board. The two available demos BSPs are 'hmi-demo' (contains various multimedia and video streaming apps) and 'qt-hmi-demo' (contains demos from the Qt framework). cd $WORK/build cp ../meta-rzg-demos/meta-rzg1/<demo_folder>/template/ /bblayers.conf ./conf cp ../meta-rzg-demos/meta-rzg1/<demo_folder>/template/ /local.conf ./conf </li>

<li> Build the BSP. The demo BSPs support only the Wayland/Weston environment, X11 is not supported: bitbake core-image-weston </li> </ol>
