ADAS Surround View Kit Documentation

Documentation is available at Renesas page. Start with User's Manual document

Tested peripherals

This extension board has been tested with I2C and avb cameras

System with LVDS cameras

Cameras:
IMI IMI Gen4 minicube automotive camera (OV10635, MAX9271)
maxim Maxim OV10635 camera
Fakra Wires

Pin-mux configuration

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 use the SD card for the rootfs. You can use nfs or a USB stick instead.

  1. Set new state of muxes four VINs configuration
    echo -n vin0_bt656_state > /sys/devices/mux.9/state
    echo -n vin1_bt656_state > /sys/devices/mux.10/state
    echo -n vin2_bt656_state > /sys/devices/mux.11/state
    echo -n vin3_bt656_state > /sys/devices/mux.12/state
    
  2. Set new state of muxes four AVB configuration
    echo -n  avb_state > /sys/devices/mux.11/state
    

Quick Start

Build image

First please visit Main R-Car Yocto Page and perform all necessary preparation steps like cloning repositories and copy binaries and config files. Then:

  1. Clone demo layer and meta-qt5
    git clone https://github.com/CogentEmbedded/meta-renesas-quick-start.git
    git clone https://github.com/CogentEmbedded/meta-qt5.git
    git clone https://github.com/CogentEmbedded/meta-clang.git
    
  2. Switch to proper branches/commits
    cd $WORK/meta-qt5
    git checkout r-car-gen2
    cd $WORK/meta-clang
    git checkout r-car-gen2
    
  3. Update conf files in $WORK/build/conf/
    cp meta-renesas-quick-start/docs/sample/conf/stout/* $WORK/build/conf/
    
  4. Build and install image
    bitbake core-image-weston
    

Boot with LVDS cameras

  1. Prepare SD card and copy next files to SD card root directory
    ./tmp/deploy/images/stout/core-image-weston-ramdisk-stout.cpio.gz.u-boot
    ./tmp/deploy/images/stout/uImage
    ./tmp/deploy/images/stout/uImage-r8a7790-stout-view.dtb
    
  2. Edit U-Boot environment configuration:
    setenv loadramdisk 'ext4load mmc 0:1 0x4C000000 /core-image-weston-stout.cpio.gz.u-boot'
    setenv loadkernel  'ext4load mmc 0:1 0x40007fc0 /uImage; ext4load mmc 0:1 0x40f00000 /uImage-r8a7790-stout-view.dtb'
    setenv setcpld 'cpld write 1 0x4966'
    setenv bootargs 'console=ttySC0,38400 ignore_loglevel rw root=/dev/ram rootwait ip=none vmalloc=384M'
    setenv bootramdisk 'bootm 0x40007fc0 0x4C000000 0x40f00000'
    setenv bootcmd 'run loadramdisk; run loadkernel; run setcpld; run bootramdisk'
    setenv bootmlow  0x41000000
    setenv bootmsize 0x0B000000
    saveenv
    

Boot with SD card and 1Gb network

  1. Prepare SD card
    sudo tar xvf ./tmp/deploy/images/stout/core-image-weston-stout.tar.bz2 -C <sdcard_mountpoint>
    
  2. Edit U-Boot environment configuration:
    setenv loadkernel  'ext4load mmc 0:1 0x40007fc0 /boot/uImage+dtb;'
    setenv setcpld 'cpld write 1 0x4164'
    setenv bootargs 'console=ttySC0,38400 ignore_loglevel rw root=/dev/mmcblk0p1 rootwait ip=none vmalloc=384M'
    setenv bootcmd 'run loadkernel; run setcpld; bootm 0x40007fc0'
    setenv bootmlow  0x41000000
    setenv bootmsize 0x0B000000
    saveenv
    
  3. After successfull boot, you will be able to use eth1 1Gb interface
    ifconfig eth1 up
    


Start Surroundview

After board successfully booted you will be able to run SurroundView application. See the manual for instructions R-Car Surround View manual on how to run and use SurroundView application. Example of usage with LVDS cameras:

cd /home/root/sv
sv-utest -v /dev/video0,/dev/video1,/dev/video2,/dev/video3

Example of usage with ethernet jpeg cameras ([] -- optional arguments):

cd /home/root/sv
sv-utest -i eth1 -m <mac1>,<mac2>,<mac3>,<mac4> -j /dev/video1 -f i420 [--proto <ethertype, default 0x88B5> --pdu_subtype <pdu subtype, default 0x2>]
