meta-agl-demo, the Yocto layer for DEMO platform of Automotive Grade Linux

The yocto layer 'meta-agl-demo' provides a demo platform and applications of AGL Distribution.

AGL is creating an automotive specific Linux distribution that unifies the software that has been written in a number of places already, such as GENIVI and Tizen IVI.

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.

For infomation for subscribing to the mailing list automotive-discussions For information about AGL Distribution, see the AGL Distribution For information abount Getting started with AGL here For information about contributing to the AGL Distro here

Packagegroups

AGL Demo Platform's package group design:

  • packagegroup-agl-demo-platform

This is for making image 'agl-demo-platform' which is full image for IVI profile of AGL distro.

As meta-agl's design of packagegroups, agl-demo-platform.bb contains only packagegroup-agl-demo-platform and packages of DEMO apps.

packagegroup-agl-demo-platform has 4 packagegroups in it, packagegroup-agl-core, packagegroup-agl-ivi, packagegroup-agl-ivi-common-core, and packagegroup-agl-appfw.

  • packagegroup-agl-appfw*

These packagegroups contains packages for application framework of AGL Distro. Subsystem should maintain packagegroup-agl-appfw-[subsystem].bb which should hold sufficient packages for application framework of AGL Distro.

Subsystems also can maintain their own packagegroups under appropriate recipes-*/.

For example, Qt5 has 2 packagegroups in meta-agl-demo, packagegroup-agl-appfw-native-qt5 and packagegroup-agl-demo-qt-examples which are under recipes-qt/.

The packagegroup-agl-appfw-native-qt5 is included by packagegroup-agl-appfw-native because Qt5 belongs to native application framework of AGL Distro.

The packagegroup-agl-demo-qt-examples is added to local.conf if needed because they are not mandatory for AGL application framework and AGL Demo Platform.

Downloading the Source

You can use repo tool to get all layers which are needed to build AGL Distribution.

  1. Installing Repo. Make sure you have a bin/ in your $HOME and it's included in your $PATH. $ mkdir ~/bin $ export PATH=~/bin:$PATH

Download the repo tool. $ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo $ chmod a+x ~/bin/repo

  1. Preparing download. Create an empty directory to hold all recipes and build environment. You can make it as any name you like. $ mkdir WORKING-DIRECTORY $ cd WORKING-DIRECTORY

  2. Getting all layers. $ repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo $ repo sync

Build a QEMU image

You can build a QEMU image using the following steps:

  1. Set up environment: You can specify any name for directory which storing all stuffs to build. $ source meta-agl/scripts/envsetup.sh qemux86-64 [BUILD_DIR]

  2. Build the full image of AGL Demo Platform and applications $ bitbake agl-demo-platform

2a. 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"

2b. The Weston IVI-Shell always gets built ; it will not be started, however, unless you specify the following in your "conf/local.conf" file :

IMAGE_INSTALL_append = " \ weston-ivi-shell-config \ " or you manually overwrite the "/etc/xdg/weston/weston.ini" file with a correct one.

  1. Run the emulator. The path for the emulator (runqemu) was added during the envsetup. $ cd tmp/deploy/images/qemex86-64 $ runqemu bzImage-qemux86-64.bin agl-demo-platform-qemux86-64.ext3

For large screen: $ runqemu bzImage-qemux86-64.bin agl-demo-platform-qemux86-64.ext3 \ bootparams="uvesafb.mode_option=1280x720-32"

To extend the amount of memory, add to runqemu: qemuparams="-m 512"

To separate console from VGA screen (to avoid corrupt screen while booting), add to runqemu: serial

or use the virtual disk in Virtual Box from this location: tmp/deploy/images/qemux86-64/agl-demo-platform-qemux86-64.vmdk

  1. Some weston samples are available from weston terminal.

Build a R-Car M2 (porter) image

Obtain and Install Renesas Graphics/Multimedia 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.

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

These 2 files from Renesas should be store in your download directory in $HOME. (e.g. $HOME/Downloads) If not, envsetup.sh in below will stop and show some instruction, then please follow it.

Build from the Source code

You can build a R-Car2 M2 (porter) image using the following steps:

  1. Set up environment: You can specify any name for directory which storing all stuffs to build. $ source meta-agl/scripts/envsetup.sh porter [BUILD_DIR]

  2. (Optional) 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'.

  1. (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.

  1. Build the full image of AGL Demo Platform and applications $ bitbake agl-demo-platform

Deployment (SDCARD)

NOTE: These instructions are based on GENIVI wiki, here.

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

  4. Go to build directory $ cd $AGL_TOP/build/tmp/deploy/images/porter
  5. 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-demo-platform-porter.tar.bz2

  6. Copy kernel and DTB into the /boot of the SD-Card $ sudo cp uImage uImage-r8a7791-porter.dtb /media/$SDCARD_LABEL/boot

  7. After the copy finished, unmount SD-Card and insert it into the SD-Card slot of the porter board.

Instructions on the target board

NOTE: There is details about porter board here.

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.

  1. 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 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

Deployment (TFTP/NFS)

NOTE: These instructions are based on Embedded Linux Wiki, here. 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
  2. Install necessary packages $ sudo apt-get install tftp tftpd-hpa
  3. 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

  4. 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

  5. set NFS server

  6. Install necessary packages $ sudo apt-get install nfs-kernel-server nfs-common
  7. 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
  8. 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.
  9. Restart nfs service $ sudo service nfs-kernel-server restart
  10. 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 sh-thd-430987335390 sys tmp usr var
