1 meta-agl-demo, the Yocto layer for DEMO platform of Automotive Grade Linux
2 ==========================================================================
4 The yocto layer 'meta-agl-demo' provides a demo platform and applications
7 AGL is creating an automotive specific Linux distribution that unifies
8 the software that has been written in a number of places already,
9 such as GENIVI and Tizen IVI.
11 The AGL community appreciates feedback, ideas, suggestion, bugs and
12 documentation just as much as code. Please join the irc conversation
13 at the #automotive channel on irc.freenode.net and our mailing list.

55 AGL Demo Platform's package group design:
57 * packagegroup-agl-demo-platform
59 This is for making image 'agl-demo-platform' which is full image
60 for IVI profile of AGL distro.
62 As meta-agl's design of packagegroups, ``agl-demo-platform.bb`` contains
63 only ``packagegroup-agl-demo-platform`` and packages of DEMO apps.
65 ``packagegroup-agl-demo-platform`` has 4 packagegroups in it,
66 ``packagegroup-agl-core``, ``packagegroup-agl-ivi``,
67 ``packagegroup-agl-ivi-common-core``, and ``packagegroup-agl-appfw``.
69 * packagegroup-agl-appfw*
71 These packagegroups contains packages for application framework of AGL Distro.
72 Subsystem should maintain ``packagegroup-agl-appfw-[subsystem].bb`` which
73 should hold sufficient packages for application framework of AGL Distro.
75 Subsystems also can maintain their own packagegroups under appropriate
78 For example, Qt5 has 2 packagegroups in ``meta-agl-demo``,
79 ``packagegroup-agl-appfw-native-qt5`` and ``packagegroup-agl-demo-qt-examples``
80 which are under ``recipes-qt/``.
82 The ``packagegroup-agl-appfw-native-qt5`` is included by
83 ``packagegroup-agl-appfw-native`` because Qt5 belongs to native application
84 framework of AGL Distro.
86 The ``packagegroup-agl-demo-qt-examples`` is added to local.conf if needed
87 because they are not mandatory for AGL application framework and AGL Demo
93 * QEMU (x86-64) - emulated machine: qemux86-64
94 * Renesas R-Car Gen2 (R-Car M2) - machine: porter
96 Supported Target of bitbake
97 ------------------------
99 * `agl-demo-platform` The full image of AGL Demo Platform and applications
101 Supposed Directory Trees of Layers to build
102 -------------------------------------------
123 Downloading the Source
125 You can use repo tool to get all layers which are needed to build AGL Distribution.
127 1. Installing Repo. Make sure you have a bin/ in your $HOME and it's included in your $PATH.
129 $ export PATH=~/bin:$PATH
131 Download the repo tool.
132 $ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
133 $ chmod a+x ~/bin/repo
135 2. Preparing download. Create an empty directory to hold all recipes and build environment. You can make it as any name you like.
136 $ mkdir WORKING-DIRECTORY
137 $ cd WORKING-DIRECTORY
139 3. Getting all layers.
140 $ repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
146 You can build a QEMU image using the following steps:
148 1. Set up environment: You can specify any name for directory which storing all stuffs to build.
149 $ source meta-agl/scripts/envsetup.sh qemux86-64 [BUILD_DIR]
151 2. Build the full image of AGL Demo Platform and applications
152 $ bitbake agl-demo-platform
154 3. The Weston IVI-Shell always gets built ; it will not be started, however, unless you specify the following in your "conf/local.conf" file :
156 IMAGE_INSTALL_append = " \
157 weston-ivi-shell-config \
160 or you manually overwrites the "/etc/xdg/weston/weston.ini" file with a correct one.
162 4. Run the emulator. The path for the emulator (runqemu) was added during the envsetup.
163 $ cd tmp/deploy/images/qemex86-64
164 $ runqemu bzImage-qemux86-64.bin agl-demo-platform-qemux86-64.ext3
167 $ runqemu bzImage-qemux86-64.bin agl-demo-platform-qemux86-64.ext3 \
168 bootparams="uvesafb.mode_option=1280x720-32"
170 5. Some weston samples are available from weston terminal.
173 Build a R-Car M2 (porter) image
174 -------------------------------
176 #### Obtain and Install Renesas Graphics/Multimedia Drivers
178 1. Download packages from Renesas
180 The graphics and multimedia acceleration packages for the R-Car M2 Porter board
181 can be download directory from [here](http://www.renesas.com/secret/r_car_download/rcar_demoboard.jsp).
183 There are 2 ZIP files can be downloaded.
184 * Multimedia and Graphics library which require registeration and click through license
185 > r-car_series_evaluation_software_package_for_linux-*.zip
186 * Related Linux drivers
187 > r-car_series_evaluation_software_package_of_linux_drivers-*.zip
189 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.
191 #### Build from the Source code
193 You can build a R-Car2 M2 (porter) image using the following steps:
195 1. Set up environment: You can specify any name for directory which storing all stuffs to build.
196 $ source meta-agl/scripts/envsetup.sh porter [BUILD_DIR]
198 2. (Optional) If you want to install various Qt5 examples, add below
199 configuration to your local.conf.
200 IMAGE_INSTALL_append = " \
201 packagegroup-agl-demo-qt-examples \
203 PACKAGECONFIG_append_pn-qtbase = " examples"
206 To run examples with wayland-egl plugin,
207 use ``LD_PRELOAD=/usr/lib/libEGL.so <command>``.
208 If not, programs should not launch by error,
211 3. (Optional) If you want to use multimedia accelerations, uncomment
212 manually 4 `IMAGE_INSTALL_append_porter` in conf/local.conf.
213 #IMAGE_INSTALL_append_porter = " \
214 # gstreamer1.0-plugins-bad-waylandsink \
217 #IMAGE_INSTALL_append_porter = " \
218 # gstreamer1.0-plugins-base-videorate \
222 #IMAGE_INSTALL_append_porter = " \
223 # libegl libegl-dev libgbm-dev \
227 #IMAGE_INSTALL_append_porter = " \
228 # packagegroup-rcar-gen2-multimedia \
232 Also it is needed to uncomment this,
233 #MACHINE_FEATURES_append = " multimedia"
235 This `multimedia` enables meta-renesas's multimedia configuration.
236 The version of GStreamer1.0 which AGL distro use, will be changed
237 to 1.2.3 (meta-renesas prefers) from 1.4.1(meta-agl default) by this switch.
239 4. Build the full image of AGL Demo Platform and applications
240 $ bitbake agl-demo-platform
242 ### Deployment (SDCARD)
244 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).
246 #### Instructions on the host
248 1. Format SD-Card and then, create single EXT3 partition on it.
250 2. Mount the SD-Card, for example `/media/$SDCARD_LABEL`.
252 3. Copy AGL root file system onto the SD-Card
253 1. Go to build directory
254 $ cd $AGL_TOP/build/tmp/deploy/images/porter
255 2. Extract the root file system into the SD-Card
256 $ sudo tar --extract --numeric-owner --preserve-permissions --preserve-order \
257 --totals --directory=/media/$SDCARD_LABEL --file=agl-demo-platform-porter.tar.bz2
258 3. Copy kernel and DTB into the `/boot` of the SD-Card
259 $ sudo cp uImage uImage-r8a7791-porter.dtb /media/$SDCARD_LABEL/boot
261 4. After the copy finished, unmount SD-Card and insert it into the SD-Card slot of the porter board.
263 #### Instructions on the host
265 NOTE: There is details about porter board [here](http://elinux.org/R-Car/Boards/Porter).
267 NOTE: To boot weston on porter board, we need keyboard and mouse. (USB2.0 can be use for this)
269 ##### Change U-Boot parameters to boot from SD card
271 1. Power up the board and, using your preferred terminal emulator, stop the board's autoboot by hitting any key.
273 > Debug serial settings are 38400 8N1. Any standard terminal emulator program can be used.
275 2. Set the follow environment variables and save them
276 => setenv bootargs_console console=ttySC6,${baudrate}
277 => setenv bootargs_video vmalloc=384M video=HDMI-A-1:1024x768-32@60
278 => setenv bootcmd_sd 'ext4load mmc 0:1 0x40007fc0 boot/uImage;ext4load mmc 0:1 0x40f00000 boot/uImage-r8a7791-porter.dtb'
279 => setenv bootcmd 'setenv bootargs ${bootargs_console} ${bootargs_video} root=/dev/mmcblk0p1 rw rootfstype=ext3;run bootcmd_sd;bootm 0x40007fc0 - 0x40f00000'
282 ##### Boot from SD card
284 1. After board reset, U-Boot is started and after a countdown, ...
285 Linux boot message should be displayed. Please wait a moment.
286 2. Then weston is booted automatically, and weston-terminal appears.
290 4. (Optional) This is how to test and play multimedia contents with acceleration.
292 1. Boot porter without mouse and keyboard, it avoid to boot weston automatically.
293 For now, when running weston, V4L2 deosn't work correctly, so we have to
294 stop weston first (GST plugin `waylandsink` also doesn't work correctly for now).
296 2. Execute these instructions:
297 $ export LD_LIBRARY_PATH="/lib:/usr/lib:/usr/local/lib:"
300 $ amixer set "LINEOUT Mixer DACL" on
301 $ amixer set "DVC Out" 10
303 $ modprobe -a mmngr mmngrbuf s3ctl uvcs_cmn vspm fdpm
305 $ media-ctl -d /dev/media0 -r
306 $ media-ctl -d /dev/media0 -l '"vsp1.2 rpf.0":1 -> "vsp1.2 uds.0":0 [1]'
307 $ media-ctl -d /dev/media0 -l '"vsp1.2 uds.0":1 -> "vsp1.2 wpf.0":0 [1]'
308 $ media-ctl -d /dev/media0 -l '"vsp1.2 wpf.0":1 -> "vsp1.2 lif":0 [1]'
309 $ media-ctl -d /dev/media0 -V '"vsp1.2 rpf.0":0 [fmt:AYUV32/1920x1080]'
310 $ media-ctl -d /dev/media0 -V '"vsp1.2 rpf.0":1 [fmt:AYUV32/1920x1080]'
311 $ media-ctl -d /dev/media0 -V '"vsp1.2 uds.0":0 [fmt:AYUV32/1920x1080]'
312 $ media-ctl -d /dev/media0 -V '"vsp1.2 uds.0":1 [fmt:AYUV32/640x480]'
313 $ media-ctl -d /dev/media0 -V '"vsp1.2 wpf.0":0 [fmt:AYUV32/640x480]'
314 $ media-ctl -d /dev/media0 -V '"vsp1.2 wpf.0":1 [fmt:ARGB32/640x480]'
315 $ media-ctl -d /dev/media0 -V '"vsp1.2 lif":0 [fmt:ARGB32/640x480]'
317 # in caes R-Car M2 (HDMI - DU1 - vspd0)
318 $ modetest -M rcar-du -s 10@8:1280x720@AR24 -d -P '8@19:640x480+100+200@XR24' &
320 After these command, Test pattern will show on display connected to
323 Then, you can play H264(MP4) movie like these,
324 $ gst-launch-1.0 filesrc location=./sample.mp4 ! qtdemux name=d d. ! \
