 Setup build environment cd $WORK source poky/oe-init-build-env </li>

 Prepare default configuration files. cp $WORK/meta-renesas/meta-rcar-gen3/docs/sample/conf/<salvator-x|h3ulcb|m3ulcb>/linaro-gcc/mmp/*.conf ./conf/ cd $WORK/build cp conf/local-wayland.conf conf/local.conf

 Edit $WORK/build/conf/local.conf to enable/disable graphics and multimedia proprietary drivers support </li>

 Edit local.conf to choose machine extension variant </li>

For ULCB ADAS boards only:

  Edit local.conf to select special IO configuration: MACHINE_FEATURES_append = " h3ulcb-had" (use this append for ADAS HAD IO configuration) </li> </ol>

</li>

 Edit local.conf with evaluation packages requirements:   For Yocto v2.23.0 (to enable EVA_ prefix during packages install) DISTRO_FEATURES_append = " use_eva_pkg" </li> </ol> </li>

 Add layer meta-rcar bitbake-layers add-layer ../meta-rcar/meta-rcar-gen3-adas </li>

 Start the build

bitbake core-image-weston </li>

<li> 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. </li>

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

</ol>

OpenCV support
OpenCV version 2.4.11 is included in build by default. To disable Opencv add this line in your local.conf: DISTRO_FEATURES_remove = " opencv-sdk " To build with OpenCV 3.2, don't add the previous line, but provide preffered version 3.2 in local.conf: PREFERRED_VERSION_opencv = "3.2+git%"

OpenCL support
The following page describes how to enable OpenCL and Caffe support: R-Car/Boards/Yocto-Gen3/OpenCL

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-2.1.2.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-2.1.2.sh

Build BSP without network
After building BSP you may archive gits and download cache and proceed developing without network. Make sure that build that you completed online included all patches from step#4 of http://elinux.org/R-Car/Boards/Yocto-Gen3-ADAS#Building_the_BSP_for_Renesas_ADAS_boards Archive the following folders: cd $WORK/build tar cfj bsp.v2.23.0.tar.bz2 meta-linaro meta-openembedded meta-rcar meta-renesas poky build/downloads Unpack archive on machine without network access and proceed building starting from step#5 of http://elinux.org/R-Car/Boards/Yocto-Gen3-ADAS#Building_the_BSP_for_Renesas_ADAS_boards Before step #13 add this option to local.conf: BB_NO_NETWORK=1 mkdir build cd build tar xfj <path_to_archive>/bsp.v2.23.0.tar.bz2

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: <ol> <li> Setup a TFTP server.

Ubuntu
Install tftpd-hpa package along with tftp tools: sudo apt-get install tftp tftpd-hpa

Fedora
<ol> <li> Install necessary packages: sudo yum install tftp-server tftp tftp-server is a part of xinetd. See Fedora manual for more information. </li> <li> Enable TFTP server: sudo vi /etc/xinetd.d/tftp Set disable = no Save file and exit. </li> <li> Start xinetd: sudo systemctl start xinetd.service sudo systemctl enable xinetd.service </li> </ol>

</li>

<li> Copy Image and Image-r8a7795-h3ulcb.dtb (for ws2.0 silicon) 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-h3ulcb.dtb /srv/tftp/

Fedora
cp $WORK/build/tmp/deploy/images/h3ulcb/Image /var/lib/tftpboot/ cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb.dtb /var/lib/tftpboot/ </li>

<li> Verify that TFTP server is working. tftp localhost -c get Image && ls Image </li>

<li> Setup NFS server.

Debian/Ubuntu
<ol> <li> Install necessary packages: sudo apt-get install nfs-kernel-server nfs-common </li> <li> Start NFS server: sudo /etc/init.d/nfs-kernel-server start </li> </ol>

Fedora
<ol> <li> Install necessary packages: sudo yum install nfs-utils </li> <li> 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 </li> </ol> </li>

<li> Export root FS to NFS. (Change IMAGE and MACHINE to fit your build). <ol> <li> Unpack rootfs to a dedicated directory: IMAGE=weston MACHINE=salvator-x|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 </li> <li> Edit /etc/exports: sudo vi /etc/exports add /nfs/h3ulcb	*(rw,no_subtree_check,sync,no_root_squash,no_all_squash) /nfs/salvator-x	*(rw,no_subtree_check,sync,no_root_squash,no_all_squash) Save the file and exit. </li> <li> Force NFS server to re-read /etc/exports sudo exportfs -a </li> </ol> </li> <li> Verify that NFS is working. [builduser@buildmachine ~]$ showmount -e localhost Export list for localhost: /nfs/h3ulcb * /nfs/salvator-x * </li>

<li> Boot into U-Boot command prompt

<ol> <li> Connect to serial console over microUSB using minicom or picocom. </li> <li> Switch the board on or reset it. Press any key to stop U-Boot automatic countdown. </li> </ol> Refer to H3SK board page, M3SK board page, Salvator-X board page for more information. </li>

<li> 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. </li>

<li> Verify the connection over Ethernet from U-Boot: ping <your-computer-ip> You should see: => ping 192.168.1.2 ravb:0 is connected to ravb. Reconnecting to ravb ravb Waiting for PHY auto negotiation to complete.. done ravb: 100Base/Full Using ravb device host 192.168.1.2 is alive </li>

<li> Reset the board by pushing reset button Refer to H3SK board page, M3SK board page, Salvator-X board page for more information. </li>

How to prepare and boot from 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.

$ 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

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:
 * 1) setenv bootargs 'rw root=/dev/mmcblk1p1 rootfstype=ext3 rootwait consoleblank=0 log_buf_len=1M'
 * 2) ext2load mmc 0:1 0x48080000 /boot/Image
 * 3) ext2load mmc 0:1 0x48000000 /boot/Image-r8a7795-h3ulcb.dtb
 * 4) booti 0x48080000 - 0x48000000'

Example of U-Boot environment variables: baudrate=115200 bootargs_emmc=rw root=/dev/mmcblk0p1 rootfstype=ext3 rootwait bootargs_nfs=rw root=/dev/nfs rootwait ip=dhcp bootargs_sd0=rw root=/dev/mmcblk1p1 rootfstype=ext3 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 bootcmd_nfs=set bootargs ${bootargs_nfs};bootp 0x48080000 Image;tftp 0x48000000 ${dtb};run booti_cmd bootcmd_sd0=set bootargs ${bootargs_sd0};ext2load mmc 0:1 0x48080000 /boot/Image;ext2load mmc 0:1 0x48000000 /boot/${dtb};run booti_cmd bootdelay=3 booti_cmd=booti 0x48080000 - 0x48000000 dtb=Image-r8a7795-h3ulcb.dtb ethact=ravb ethaddr=2E:09:0A:00:BE:11 fdt_high=0xffffffffffffffff initrd_high=0xffffffffffffffff stderr=serial stdin=serial stdout=serial ver=U-Boot 2015.04 (Sep 23 2016 - 13:45:29) Environment size: 1092/131068 bytes

Flashing firmware
In case you have absolutely new R-Car H3 or M3 board, you need to update firmware. Please refer to page R-Car H3SK or R-Car M3SK for the instructions on flashing firmware.

SurroundView GPU version
<ol> <li> Clone and build sv-utest application (see the README.md file as well): git clone https://github.com/CogentEmbedded/sv-utest.git cd sv-utest . <SDK_INSTALL_PATH>/environment-setup-aarch64-poky-linux mkdir build cd build cmake -DSV_TARGET_PLATFORM=GEN3 ../ make </li> <li> Copy the resulted binaries on rootfs. As example, for SD card: mkdir /home/root/sv sudo cp sv-utest/bin/sv-utest /usr/bin/ sudo cp sv-utest/libs/gen3/libsv.so /usr/lib/ sudo cp -r sv-utest/resources/* /home/root/sv/ </li> <li> See the manual for instructions R-Car Surround View manual on how to run and use SurroundView application. In short: cd /home/root/sv sv-utest -v /dev/video0,/dev/video1,/dev/video2,/dev/video3 </li> <li> By default 1280x800 resolution is used for cameras, but you can change it with --camres option: sv-utest -v /dev/video0,/dev/video1,/dev/video2,/dev/video3 --camres 1280x1080 </li> </ol>

SurroundView IMR version
<ol> <li> Save mesh object file from the GPU SurroundView: after calibartion and sphere adjusting are done, press S, then "=" on the main 3d view to save mesh file. Mesh object file name is "meshFull.obj" in the current working directory of SurroundView. </li> <li> Clone and build imr-sv-utest application (see the README.md file as well): git clone https://github.com/CogentEmbedded/imr-sv-utest.git cd imr-sv-utest . <SDK_INSTALL_PATH>/environment-setup-aarch64-poky-linux mkdir build cd build cmake -DIMR_TARGET_PLATFORM=GEN3 ../ make IMR SuroundView executable stored ../bin directory. </li> <li> It's need to generate png files with car model images before running IMR SurroundView. Copy executable "gen" from "prebuilt/GEN3" directory to the H3 board. Example of generation png files with car (avalaible only for Gen3): ./gen -w -h -c -o -s -m \ -l -S -d ./gen -w 1920 -h 1080 -c 0x404040FF -o ./data/model -s 8:32:8 -m Car.obj -l 1.0  -S -0.2:-0.10:0.2:0.10 </li> <li> Run the IMR SurroundView with the generated png files: For 4-cameras environment: ./imr-wl -f uyvy -v /dev/video0,/dev/video1,/dev/video2,/dev/video3 -w 1280 -h 800 -W 1920 -H 1080 \ -r /dev/video4,/dev/video5,/dev/video6,/dev/video7,/dev/video4,/dev/video5,/dev/video6,/dev/video7 -m ./data/model \ -M meshFull.obj -X 1920 -Y 1080 -S -0.30:-0.10:0.30:0.10 -g 1.0 -s 8:32:8 For 8-cameras environment: ./imr-wl -f uyvy -v /dev/video0,/dev/video1,/dev/video2,/dev/video3 -w 1280 -h 800 -W 1920 -H 1080 \ -r /dev/video8,/dev/video9,/dev/video10,/dev/video11,/dev/video8,/dev/video9,/dev/video10,/dev/video11 -m ./data/model \ -M meshFull.obj -X 1920 -Y 1080 -S -0.30:-0.10:0.30:0.10 -g 1.0 -s 8:32:8 Run "./imr-wl -h" for options explanation. </li> </ol>

8 Camera Demo (GPU + IMR version)
Demo application demonstrates surround view with pre-defined viewpoints on Renesas boards with 4 additional cameras for mirror replacement purposes. First additional camera works as driver monitor.

<ol> <li> Save mesh object file from the GPU SurroundView: after calibartion and sphere adjusting are done, press S, then "=" on the main 3d view to save mesh file. Mesh object file name is "meshFull.obj" in the current working directory of SurroundView. </li> <li> Clone and build 8-cam-imr-gpu-sv-utest application (see the README.md file as well): git clone https://github.com/CogentEmbedded/8-cam-imr-gpu-sv-utest.git cd 8-cam-imr-gpu-sv-utest . <SDK_INSTALL_PATH>/environment-setup-aarch64-poky-linux mkdir build cd build cmake ../ make Demo executable "sc" stored ../bin directory. </li> <li> It's need to generate png files with car model images before running IMR SurroundView. Copy executable "gen" from "prebuilt/" directory to the H3 board. Example of generation png files with car (avalaible only for Gen3): ./gen -w -h -c -o -s -m \ -l -S -d ./gen -w 1920 -h 1080 -c 0x404040FF -o ./data/model -s 8:32:8 -m Car.obj -l 1.0  -S -0.2:-0.10:0.2:0.10 </li> <li> Copy resources files to directory where application will be runned from "resources/". Copy libdrivermonitor.so and libsv.so from "lib/" directory to rootfs. Copy "resources/adas-utest" directory to /usr/share on rootfs. </li> <li> Run the application: ./sc -W 1920 -H 1080 -m ./data/model -M meshFull.obj -X 1920 -Y 1080 -g 1.0 -b 0x000000 -c config.txt -S -0.20:-0.1:0.20:0.1 -s 8:32:8 </li> <li> To control application with SpaceNav start SpaceNav daemon: spacenavd command. There are 5 widgets on the main screen: main 3d SurroundView screen, DriverMonitor camera, right, left and rear mirror replacement cameras.

To change focus on widget press right button on SpaceNav. To change zoom and view on mirror replacement cameras rotate SpaceNav joystick, when widget is in focus. To hide Driver Monitor camera and mirror cameras press and hold left button on joystick, when widget is in focus. To switch to IMR demo press left button on SpaceNav joystick, when main 3d SurroundView in focus. To get back from IMR demo press left button again. To rotate view in IMR demo use joystick or touchscreen.

Camera demo for VIN-IMR-DRM capture pipe
Unit test application demonstrates IMR-DRM usage on systems that have no GPU (r8a7797). The test application name is 'utest-cam-imr-drm'. The unit test is provided in sources and built within yocto. <ol> <li> The unit test is located on rootfs for core-image-minimal build (tested on V3MSK). To launch the application issue the following command with 4 cameras connected: $ utest-cam-imr-drm </li> </ol> NOTE: unit test assumes use of 4 cameras at resolution 1280x1080 To use other then 4 amount of cameras, then modify CAMERAS_NUMBER definition in source code (meta-rcar/meta-rcar-gen3-adas/recipes-bsp/utest-apps/files/utest-cam-imr-drm.tar.gz) To use other resolution use parameters 'h' and 'w': $ utest-cam-imr-drm -w 1280 -h 800

Camera low level tests
It is possible to run low level tests to validate LVDS cameras. The test application name is 'capture'. The 'capture' is provided in sources and build within yocto. <ol> <li> The test examples are located on rootfs path: $ ls -1 /usr/share/tests/ test_lvds_2cameras_on_display1920x1080.sh test_lvds_4cameras_on_display1920x1080.sh test_lvds_8cameras_on_display1920x1080.sh test_lvds_camera_0-3.sh test_lvds_camera_0.sh test_lvds_camera_4-7.sh test_lvds_camera_4.sh </li> </ol>
