+
+Build a R-Car M2 (porter) image
+-------------------------------
+
+### Software setup
+
+NOTE: These instructions are based on GENIVI wiki, [here](http://wiki.projects.genivi.org/index.php/Hardware_Setup_and_Software_Installation/koelsch%26porter). If these didn't work correctly especially around Renesas Binary Packages, please check there and updated instructions.
+
+#### Getting Source Code and Build image
+
+1. Create a directory for working, then go to there.
+ $ mkdir -p $HOME/ANYWHERE_YOU_WANT_TO_WORK_THERE
+ $ cd $HOME/ANYWHERE_YOU_WANT_TO_WORK_THERE
+ $ export AGL_TOP=`pwd`
+
+2. Get the meta data and checkout
+ $ git clone git://git.yoctoproject.org/poky
+ $ cd poky
+ $ git checkout df87cb27efeaea1455f20692f9f1397c6fcab254
+ $ cd -
+ $ git clone git://git.openembedded.org/meta-openembedded
+ $ cd meta-openembedded
+ $ git checkout 9efaed99125b1c4324663d9a1b2d3319c74e7278
+ $ cd -
+ $ git clone https://gerrit.automotivelinux.org/gerrit/AGL/meta-renesas
+ $ cd meta-renesas
+ $ git checkout bf30de66badcac7ef82d3758aa44c116ee791a28
+ $ cd -
+ $ git clone https://gerrit.automotivelinux.org/gerrit/AGL/meta-agl
+
+#### Obtain and Install Renesas Graphics Drivers
+
+1. Download packages from Renesas
+
+ The graphics and multimedia acceleration packages for the R-Car M2 Porter board
+ can be download directory from [here](http://www.renesas.com/secret/r_car_download/rcar_demoboard.jsp).
+
+ There are 2 ZIP files can be downloaded.
+ * Multimedia and Graphics library which require registeration and click through license
+ > r-car_series_evaluation_software_package_for_linux-*.zip
+ * Related Linux drivers
+ > r-car_series_evaluation_software_package_of_linux_drivers-*.zip
+
+2. Unzip the two downloads into a temporary directory.
+ $ cd $AGL_TOP
+ $ mkdir binary-tmp
+ $ cd binary-tmp
+ $ unzip PATH_TO_DOWNLOAD/r-car_series_evaluation_software_package_for_linux-*.zip
+ $ unzip PATH_TO_DOWNLOAD/r-car_series_evaluation_software_package_of_linux_drivers-*.zip
+
+ After this step there should be two files in binary-tmp:
+ * Multimedia and Graphics library
+ > R-Car_Series_Evaluation_Software_Package_for_Linux-*.tar.gz
+ * Related Linux drivers
+ > R-Car_Series_Evaluation_Software_Package_of_Linux_Drivers-*.tar.gz
+
+3. Copy the graphics acceleration drivers by shell script.
+ $ cd $AGL_TOP/meta-renesas/meta-rcar-gen2
+ $ ./copy_gfx_software_porter.sh ../../binary-tmp
+
+4. Copy the multimedia acceleration drivers by shell script.
+ $ cd $AGL_TOP/meta-renesas/meta-rcar-gen2
+ $ ./copy_mm_software_lcb.sh ../../binary-tmp
+
+#### Build from the Source code
+
+You can build a R-Car2 M2 (porter) image using the following steps:
+
+1. Export TEMPLATECONF to pick up correct configuration for the build
+ $ export TEMPLATECONF=$AGL_TOP/meta-renesas/meta-rcar-gen2/conf
+
+2. Run the following command:
+ $ cd $AGL_TOP
+ $ source poky/oe-init-build-env
+
+ Edit conf/bblayers.conf then remove this line.
+ ##OEROOT##/../meta-agl-demo \
+
+ (Optional) If you want to use multimedia accelerations, confirm your
+ conf/bblayer.conf has a entry of `meta-openembedded/meta-multimedia`
+ in BBLAYERS because packagegroup-rcar-gen2-multimedia needs some extra
+ packages there.
+
+3. (Optional) If you want to use multimedia accelerations, uncomment
+ manually 4 `IMAGE_INSTALL_append_porter` in conf/local.conf.
+ #IMAGE_INSTALL_append_porter = " \
+ # gstreamer1.0-plugins-bad-waylandsink \
+ # "
+
+ #IMAGE_INSTALL_append_porter = " \
+ # gstreamer1.0-plugins-base-videorate \
+ ...
+ #"
+
+ #IMAGE_INSTALL_append_porter = " \
+ # libegl libegl-dev libgbm-dev \
+ ...
+ # "
+
+ #IMAGE_INSTALL_append_porter = " \
+ # packagegroup-rcar-gen2-multimedia \
+ ...
+ # "
+
+ Also it is needed to uncomment this,
+ #MACHINE_FEATURES_append = " multimedia"
+
+ This `multimedia` enables meta-renesas's multimedia configuration.
+ The version of GStreamer1.0 which AGL distro use, will be changed
+ to 1.2.3 (meta-renesas prefers) from 1.4.1(meta-agl default) by this switch.
+
+4. Build the minimal image of AGL Distribution
+ $ bitbake agl-image-ivi
+
+### Deployment (SDCARD)
+
+NOTE: These instructions are based on GENIVI wiki, [here](http://wiki.projects.genivi.org/index.php/Hardware_Setup_and_Software_Installation/koelsch%26porter#Deployment_.28SDCARD.29).
+
+#### Instructions on the host
+
+1. Format SD-Card and then, create single EXT3 partition on it.
+
+2. Mount the SD-Card, for example `/media/$SDCARD_LABEL`.
+
+3. Copy AGL root file system onto the SD-Card
+ 1. Go to build directory
+ $ cd $AGL_TOP/build/tmp/deploy/images/porter
+ 2. Extract the root file system into the SD-Card
+ $ sudo tar --extract --numeric-owner --preserve-permissions --preserve-order \
+ --totals --directory=/media/$SDCARD_LABEL --file=agl-image-ivi-porter.tar.bz2
+ 3. Copy kernel and DTB into the `/boot` of the SD-Card
+ $ sudo cp uImage uImage-r8a7791-porter.dtb /media/$SDCARD_LABEL/boot
+
+4. After the copy finished, unmount SD-Card and insert it into the SD-Card slot of the porter board.
+
+#### Instructions on the host
+
+NOTE: There is details about porter board [here](http://elinux.org/R-Car/Boards/Porter).
+
+NOTE: To boot weston on porter board, we need keyboard and mouse. (USB2.0 can be use for this)
+
+##### Change U-Boot parameters to boot from SD card
+
+1. Power up the board and, using your preferred terminal emulator, stop the board's autoboot by hitting any key.
+
+ > Debug serial settings are 38400 8N1. Any standard terminal emulator program can be used.
+
+2. Set the follow environment variables and save them
+ => setenv bootargs_console console=ttySC6,${baudrate}
+ => setenv bootargs_video vmalloc=384M video=HDMI-A-1:1024x768-32@60
+ => setenv bootcmd_sd 'ext4load mmc 0:1 0x40007fc0 boot/uImage;ext4load mmc 0:1 0x40f00000 boot/uImage-r8a7791-porter.dtb'
+ => setenv bootcmd 'setenv bootargs ${bootargs_console} ${bootargs_video} root=/dev/mmcblk0p1 rw rootfstype=ext3;run bootcmd_sd;bootm 0x40007fc0 - 0x40f00000'
+ => saveenv
+
+##### Boot from SD card
+
+1. After board reset, U-Boot is started and after a countdown, ...
+ Linux boot message should be displayed. Please wait a moment.
+2. Then weston is booted automatically, and weston-terminal appears.
+
+3. Have fun! :)
+
+4. (Optional) This is how to test and play multimedia contents with acceleration.
+
+ 1. Boot porter without mouse and keyboard, it avoid to boot weston automatically.
+ For now, when running weston, V4L2 deosn't work correctly, so we have to
+ stop weston first (GST plugin `waylandsink` also doesn't work correctly for now).
+
+ 2. Execute these instructions:
+ $ export LD_LIBRARY_PATH="/lib:/usr/lib:/usr/local/lib:"
+
+ # Set the mixer
+ $ amixer set "LINEOUT Mixer DACL" on
+ $ amixer set "DVC Out" 10
+
+ $ modprobe -a mmngr mmngrbuf s3ctl uvcs_cmn vspm fdpm
+
+ $ media-ctl -d /dev/media0 -r
+ $ media-ctl -d /dev/media0 -l '"vsp1.2 rpf.0":1 -> "vsp1.2 uds.0":0 [1]'
+ $ media-ctl -d /dev/media0 -l '"vsp1.2 uds.0":1 -> "vsp1.2 wpf.0":0 [1]'
+ $ media-ctl -d /dev/media0 -l '"vsp1.2 wpf.0":1 -> "vsp1.2 lif":0 [1]'
+ $ media-ctl -d /dev/media0 -V '"vsp1.2 rpf.0":0 [fmt:AYUV32/1920x1080]'
+ $ media-ctl -d /dev/media0 -V '"vsp1.2 rpf.0":1 [fmt:AYUV32/1920x1080]'
+ $ media-ctl -d /dev/media0 -V '"vsp1.2 uds.0":0 [fmt:AYUV32/1920x1080]'
+ $ media-ctl -d /dev/media0 -V '"vsp1.2 uds.0":1 [fmt:AYUV32/640x480]'
+ $ media-ctl -d /dev/media0 -V '"vsp1.2 wpf.0":0 [fmt:AYUV32/640x480]'
+ $ media-ctl -d /dev/media0 -V '"vsp1.2 wpf.0":1 [fmt:ARGB32/640x480]'
+ $ media-ctl -d /dev/media0 -V '"vsp1.2 lif":0 [fmt:ARGB32/640x480]'
+
+ # in caes R-Car M2 (HDMI - DU1 - vspd0)
+ $ modetest -M rcar-du -s 10@8:1280x720@AR24 -d -P '8@19:640x480+100+200@XR24' &
+
+ After these command, Test pattern will show on display connected to
+ porter's HDMI port.
+
+ Then, you can play H264(MP4) movie like these,
+ $ gst-launch-1.0 filesrc location=./sample.mp4 ! qtdemux name=d d. ! \
+ queue ! omxh264dec no-copy=true ! v4l2sink device=/dev/video1 \
+ io-mode=userptr d. ! queue ! faad ! alsasink device=hw:0,0
