+?README-AGL.md: The Automotive Grade Linux Distribution
+======================================================
+
+AGL is creating an automotive specific Linux distribution (AGL UCB)
+that unifies the software that has been written in a number of places already,
+such as GENIVI and Tizen IVI.
+
+The layer 'meta-agl' provides a minimal set of software
+to boot system of AGL Distribution. 'meta-agl' is the minimal
+core which is used build AGL profiles on top of it.
+
+The reference UI is part of 'meta-agl-demo'.
+
+Additional components like the security framework are part of 'meta-agl-extra'.
+
+The AGL community appreciates feedback, ideas, suggestion, bugs and
+documentation just as much as code. Please join the irc conversation
+at the #automotive channel on irc.freenode.net and our mailing list.
+

+Quick start guide
+-----------------
+(latest version here: https://wiki.automotivelinux.org/agl-distro/source-code)
+To build an image from 'meta-agl'
+
+1. Prepare repo:
+ > $ mkdir ~/bin
+ > $ export PATH=~/bin:$PATH
+ > $ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
+ > $ chmod a+x ~/bin/repo
+
+2. Get all layers:
+ > $ repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
+ > $ repo sync
+
+3. Check available targets and extensions, select target machine:
+ > $ source meta-agl/scripts/aglsetup.sh -h
+ > $ source meta-agl/scripts/aglsetup.sh -m porter
+
+4. Build agl-image-ivi
+ > $ bitbake agl-image-ivi
+
+To build the agl-demo-platform (as demo'ed @ALS) replace 3. and 4. with:
+3. Check available targets and extensions, select target machine:
+ > $ source meta-agl/scripts/aglsetup.sh -h
+ > $ source meta-agl/scripts/aglsetup.sh -m porter agl-demo [agl-appfw-smack] [agl-devel] [agl-netboot]
+
+4. Build agl-demo-platform
+ > $ bitbake agl-demo-platform
+Note: this uses more layers and not only meta-agl
+

+Build a QEMU image
+------------------
+
+You can build a QEMU image using the following steps:
+
+(latest version here: https://wiki.automotivelinux.org/agl-distro/source-code)
+To build an image from 'meta-agl'
+
+1. Prepare repo:
+ > $ mkdir ~/bin
+ > $ export PATH=~/bin:$PATH
+ > $ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
+ > $ chmod a+x ~/bin/repo
+
+2. Get all layers:
+ > $ repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
+ > $ repo sync
+
+3. Check available targets and extensions, select target machine:
+ > $ source meta-agl/scripts/aglsetup.sh -h
+ > $ source meta-agl/scripts/aglsetup.sh -m qemux86-64
+
+ Alternatively, to enable the reference UI feature ('agl-demo'):
+ > $ source meta-agl/scripts/aglsetup.sh -m qemux86-64 agl-demo
+
+ Alternatively, to also enable also the security framework ('agl-appfw-smack'):
+ > $ source meta-agl/scripts/aglsetup.sh -m qemux86-64 agl-demo agl agl-appfw-smack
+
+ Alternatively, to also enable debugging tools ('agl-devel') and the network-boot (nbd) capabilities ('agl-netboot'):
+ > $ source meta-agl/scripts/aglsetup.sh -m qemux86-64 agl-demo agl agl-appfw-smack agl-devel agl-netboot
+
+4. Build agl-image-ivi
+ > $ bitbake agl-image-ivi
+
+ or alternatively, if you enabled the 'agl-demo' feature:
+ > $ bitbake agl-demo-platform
+
+ - If you want to run QEMU directly as VM in Virtual Box or your other favorite VM software then add this line to your "conf/local.conf" file.
+ > IMAGE_FSTYPES += "vmdk"
+
+5. Run in the emulator
+ > $ runqemu agl-image-ivi qemux86-64
+ > or
+ > $ runqemu agl-demo-platform qemux86-64
+
+ For a large screen:
+ > $ runqemu agl-image-ivi qemux86-64 bootparams="uvesafb.mode_option=1280x720-32"
+
+ To extend the amount of memory, add to runqemu:
+ qemuparams="-m 512"
+ > $ runqemu agl-image-ivi qemux86-64 qemuparame="-m 512" bootparams="uvesafb.mode_option=1280x720-32"
+
+
+ To separate console from VGA screen (to avoid corrupt screen while booting),
+ add to runqemu:
+ serial
+ > $ runqemu agl-image-ivi qemux86-64 bootparams="uvesafb.mode_option=1280x720-32" serial
+
+ **Or use the virtual disk in Virtual Box from this location:**
+ > tmp/deploy/images/qemux86-64/agl-demo-platform-qemux86-64.vmdk
+
+6. Some weston samples are available from weston terminal (click top left icon).
+ Check the folder `/opt/AGL/ALS2016`.
+
+Build a R-Car M2 (porter) image
+-------------------------------
+
+### Software setup
+
+NOTE: You will need to download the matching binary driver package from renesas.
+ As of this writing, the version from 20151228.
+ The main URL to retrieve these is:
+
+ - https://www.renesas.com/en-eu/solutions/automotive/rcar-demoboard.html
+
+ As of this writing, the necessary libary and driver packages linked to
+ by above site are:
+ - The subpage for the library is:
+ - https://www.renesas.com/en-eu/software/D3017410.html (registration/login required)
+
+ - The sub-page for the driver is:
+ - https://www.renesas.com/en-eu/media/secret/solutions/automotive/rcar-demoboard/R-Car_Series_Evaluation_Software_Package_of_Linux_Drivers-20151228.zip
+
+ !!! The files need to be in `${HOME}/Downloads` ( `$XDG_DOWNLOAD_DIR` ) !!!
+
+#### Getting Source Code and Build image
+
+(latest version here: https://wiki.automotivelinux.org/agl-distro/source-code)
+To build an image from 'meta-agl' only:
+
+1. Prepare repo:
+ > $ mkdir ~/bin
+ > $ export PATH=~/bin:$PATH
+ > $ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
+ > $ chmod a+x ~/bin/repo
+
+2. Get all layers:
+ > $ repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
+ > $ repo sync
+
+3. Check available targets and extensions, select target machine:
+ > $ source meta-agl/scripts/aglsetup.sh -h
+ > $ source meta-agl/scripts/aglsetup.sh -m porter
+
+ Alternatively, to enable the reference UI:
+ > $ source meta-agl/scripts/aglsetup.sh -m porter agl-demo
+
+ Alternatively, to also enable also the security framework:
+ > $ source meta-agl/scripts/aglsetup.sh -m porter agl-demo agl agl-appfw-smack
+
+ Alternatively, to also enable debugging tools and the network-boot (nbd) capabilities:
+ > $ source meta-agl/scripts/aglsetup.sh -m porter agl-demo agl agl-appfw-smack agl-devel agl-netboot
+
+4. (optional) edit conf/local.conf )* see below
+ > $ vi conf/local.conf
+
+5. Build agl-image-ivi
+ > $ bitbake agl-image-ivi
+
+ or alternatively, if you enabled the 'agl-demo' feature:
+ > $ bitbake agl-demo-platform
+
+
+)* :
+
+ 4 . Optional edits to conf/local.conf
+
+ * 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` MACHINE_FEATURES enables the meta-renesas's specific multimedia configuration.
+ The version of GStreamer1.0 which AGL distro will use is changed
+ to 1.2.3 (meta-renesas prefers it) over 1.4.1 (meta-agl default)
+ by this switch.
+
+* If you want to install various Qt5 examples, add below
+ configuration to your local.conf.
+> IMAGE_INSTALL_append = " \
+> packagegroup-agl-demo-qt-examples \
+> "
+> PACKAGECONFIG_append_pn-qtbase = " examples"
+>
+> IMPORTANT NOTE:
+> To run examples with wayland-egl plugin,
+> use ``LD_PRELOAD=/usr/lib/libEGL.so <command>``.
+> If not, programs should not launch by error,
+> 'EGL not available'.
+
+
+### Deployment (SDCARD)
+
+#### Instructions on the host
+
+1. Format SD-Card and then, create single EXT4 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/$SDCARD_LABEL/boot
+
+4. After the copy finished, unmount SD-Card and insert it into the SD-Card slot of the porter board.
+
+#### Instructions on the target
+
+NOTE: There is details about porter board [here](http://elinux.org/R-Car/Boards/Porter).
+
+NOTE: To boot weston on porter board, we need keyboard and mouse. (USB2.0 can be use for this)
+
+##### Change U-Boot parameters to boot from SD card
+
+1. Power up the board and, using your preferred terminal emulator, stop the board's autoboot by hitting any key.
+
+ ``Debug serial settings are 38400 8N1. Any standard terminal emulator program can be used.**
+
+2. Set the follow environment variables and save them
+> => setenv bootargs_console console=ttySC6,${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
+
+ # Set the mixer
+> $ 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 case 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 this:
+
+> $ 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
+
+
+### Deployment (TFTP/NFS)
+
+NOTE: These instructions are based on Embedded Linux Wiki, [here](http://www.elinux.org/R-Car/Boards/Yocto#Loading_kernel_via_TFTP_and_rootfs_via_NFS). And a Debian (wheezy, ip: 192.168.30.70) is used as the host for this instructions.
+
+#### Instructions on the host
+1. Setup a TFTP server
+ 1. Install necessary packages
+ > $ sudo apt-get install tftp tftpd-hpa
+
+ 2. Go to build directory, and copy kernel and DTB into TFTP server root (default server dir: /srv/tftp)
+ > $cd $AGL_TOP/build/tmp/deploy/images/porter
+ > $ sudo cp uImage uImage-r8a7791-porter.dtb /srv/tftp
+
+ 3. Verify TFTP server is working
+ > $ ls uImage
+ ls: cannot access uImage: No such file or directory
+
+ > $ cd /tmp/
+ > $ tftp 192.168.30.70
+ > tftp> get uImage
+ > Received 3583604 bytes in 0.2 seconds
+ > tftp> q
+ > $ ls uImage
+ > uImage
+
+2. set NFS server
+ 1. Install necessary packages
+ > $ sudo apt-get install nfs-kernel-server nfs-common
+
+ 2. Go to build directory, and extract the root file system into a dedicated directory (here we use /nfs/porter)
+ > $ cd $AGL_TOP/build/tmp/deploy/images/porter
+ > $ sudo mkdir -p /nfs/porter
+ > $ sudo tar --extract --numeric-owner --preserve-permissions --preserve-order \
+ > --totals --directory=/nfs/porter --file=agl-demo-platform-porter.tar.bz2
+
+ 3. Edit /etc/exports
+ > $ sudo vi /etc/exports
+ Add
+ >
+ > /nfs/porter *(rw,no_subtree_check,sync,no_root_squash,no_all_squash)
+ >
+ Save the file and exit.
+
+ 4. Restart nfs service
+ > $ sudo service nfs-kernel-server restart
+
+ 5. Verify NFS server is working
+ > $ sudo mount -t nfs 192.168.30.70:/nfs/porter /tmp/
+ > $ ls /tmp
+ > bin boot dev etc home lib media mnt proc run sbin sys tmp usr var
+
+#### Instructions on the target board
+
+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 TFTP/NFS
+
+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 ipaddr <board-ip>
+> => setenv serverip <host-ip>
+> => setenv bootargs_console console=ttySC6,${baudrate}
+> => setenv bootargs_video vmalloc=384M video=HDMI-A-1:1024x768-32@60
+> => setenv bootcmd_net 'tftp 0x40007fc0 uImage; tftp 0x40f00000 uImage-r8a7791-porter.dtb'
+> => setenv bootcmd 'setenv bootargs ${bootargs_console} ${bootargs_video} ip=${ipaddr} root=/dev/nfs nfsroot=${serverip}:/nfs/porter,vers=3;run bootcmd_net;bootm 0x40007fc0 - 0x40f00000'
+> => saveenv
+
+ Replace <board-ip> with a proper IP address for the board, like 192.168.30.60.
+ Replace <host-ip> with the IP address of the host, here we use 192.168.30.70.
+
+##### Boot from TFTP/NFS
+
+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! :)
