First please visit Main R-Car Yocto Page and peform all necessary preparation steps like cloning repositories and copy binaries and config files. Then:   Clone demo layer and meta-qt5 git clone TBD git clone https://github.com/meta-qt5/meta-qt5.git cd $WORK/meta-qt5 git checkout -b tmp 6d9e2a6dfc21f7d9a3a11b4bcb426b5dfe6feaeb   Edit $WORK/meta-qt5/recipes-qt/qt5/qtmultimedia_git.bb for compatibility with current bitbake version -EXTRA_QMAKEVARS_PRE += "${@bb.utils.contains_any('PACKAGECONFIG', 'gstreamer gstreamer010', '', 'CONFIG+=done_config_gstreamer', d)}" +EXTRA_QMAKEVARS_PRE += "${@bb.utils.contains('PACKAGECONFIG', 'gstreamer', '', 'CONFIG+=done_config_gstreamer', d)}"   Add necessary layers to $WORK/build/conf/bblayers.conf ${TOPDIR}/../meta-renesas-quick-start \ ${TOPDIR}/../meta-qt5 \ ${TOPDIR}/../meta-openembedded/meta-ruby \ ${TOPDIR}/../meta-openembedded/meta-networking \   Please download and prepare necessary binaries form TBD   Build and install image as it's described in   Copy application surroundview into rootfs image   After all this steps you can start working with boards and apps.

Start Surroundview
As mentioned in R-Car/Boards/Stout:CPLD VIN and AVB Ethernet pins are routed thru configurable cpld. Thus before starting surround view application you should configure either VINs 0-3 either Ethernet AVB Warning! Using 4 VINs blocks sd card. You should not SD card for foot fs. You can use nfs instead.   Set new state of muxes four VINs configuration echo -n vin0_bt656_state > /sys/devices/mux.7/state echo -n vin1_bt656_state > /sys/devices/mux.8/state echo -n vin2_bt656_state > /sys/devices/mux.9/state echo -n vin3_bt656_state > /sys/devices/mux.10/state Set new state of muxes four AVB configuration echo -n avb_state > /sys/devices/mux.9/state </li>  Start surroundview ./surroundView_renesas_lvds.sh </li> </ol>
