1 meta-agl, the Yocto layer for Automotive Grade Linux Distribution
2 =================================================================
4 The yocto layer 'meta-agl' provides a minimal set of software
5 to boot system of AGL Distribution.
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.

46 There are 3 layers in top-level `meta-agl`.
48 `meta-ivi-common` is a layer which contains common packages to AGL
49 Distribution and other platforms for In-Vehicle Infotainment system.
50 > meta-agl/meta-ivi-common
52 `meta-agl` is a layer which contains AGL common and middleware packages.
55 `meta-agl-bsp` is a layer which contains required packages to boot AGL
56 distribution on an emulated machine(QEMU).
57 > meta-agl/meta-agl-bsp
62 AGL package group design:
64 * packagegroup-agl-core*
66 These are for making image ``agl-image-minimal`` which is small image just
67 capable of allowing a device to boot.
69 Subsystem should maintain packagegroup-agl-core-[subsystem].bb which should
70 hold sufficient packages to build ``agl-image-minimal``.
72 * packagegroup-agl-ivi*
74 These are for making image ``agl-image-ivi`` which is baseline for IVI profile
75 of AGL distro. 'Baseline' means Service Layer and Operating System Layer defined
76 in AGL Spec v1.0. I think this is the same as GENIVI baseline.
77 All packages which belong to AppHMI and Application Framework should be put
78 into ``meta-agl-demo``.
80 * packagegroup-ivi-common*
82 These are for picking up some packages from GENIVI/Tizen/Others. The layer of
83 ``meta-ivi-common`` has no image to build, all packagegroups are aggregated
84 to ``packagegrou-ivi-common-core' and it is included by images,
85 ``agl-image-ivi.bb`` and ``agl-demo-platform.bb``.
90 * QEMU (x86-64) - emulated machine: qemux86-64
91 * Renesas R-Car Gen2 (R-Car M2) - machine: porter
93 Supported Target of bitbake
94 ------------------------
96 * `agl-image-ivi` The baseline image of AGL Distributions
98 * `agl-image-minimal` For internal use to develop distribution (experimental)
99 * `agl-image-weston` For internal use to develop distribution (experimental)
101 Supposed Directory Trees of Layers to build
102 -------------------------------------------
122 You can build a QEMU image using the following steps:
124 1. Export TEMPLATECONF to pick up correct configuration for the build
125 > $ export TEMPLATECONF=/full/path/to/meta-agl/meta-agl/conf
127 2. Run the following command:
128 > $ source poky/oe-init-build-env
130 3. Build the minimal image of AGL Distribution
131 > $ bitbake agl-image-ivi
134 > $ PATH_TO_POKY/poky/scripts/runqemu agl-image-ivi qemux86-64
137 > $ PATH_TO_POKY/poky/scripts/runqemu agl-image-ivi qemux86-64 bootparams="uvesafb.mode_option=1280x720-32"
139 5. Some weston samples are available from weston terminal.
141 Build a R-Car M2 (porter) image
142 -------------------------------
146 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.
148 #### Getting Source Code and Build image
150 1. Create a directory for working, then go to there.
151 $ mkdir -p $HOME/ANYWHERE_YOU_WANT_TO_WORK_THERE
152 $ cd $HOME/ANYWHERE_YOU_WANT_TO_WORK_THERE
153 $ export AGL_TOP=`pwd`
155 2. Get the meta data and checkout
156 $ git clone git://git.yoctoproject.org/poky
158 $ git checkout df87cb27efeaea1455f20692f9f1397c6fcab254
160 $ git clone git://git.openembedded.org/meta-openembedded
161 $ cd meta-openembedded
162 $ git checkout 9efaed99125b1c4324663d9a1b2d3319c74e7278
164 $ git clone https://gerrit.automotivelinux.org/gerrit/AGL/meta-renesas
166 $ git checkout bf30de66badcac7ef82d3758aa44c116ee791a28
168 $ git clone https://gerrit.automotivelinux.org/gerrit/AGL/meta-agl
170 #### Obtain and Install Renesas Graphics Drivers
172 1. Download packages from Renesas
174 The graphics and multimedia acceleration packages for the R-Car M2 Porter board
175 can be download directory from [here](http://www.renesas.com/secret/r_car_download/rcar_demoboard.jsp).
177 There are 2 ZIP files can be downloaded.
178 * Multimedia and Graphics library which require registeration and click through license
179 > r-car_series_evaluation_software_package_for_linux-*.zip
180 * Related Linux drivers
181 > r-car_series_evaluation_software_package_of_linux_drivers-*.zip
183 2. Unzip the two downloads into a temporary directory.
187 $ unzip PATH_TO_DOWNLOAD/r-car_series_evaluation_software_package_for_linux-*.zip
188 $ unzip PATH_TO_DOWNLOAD/r-car_series_evaluation_software_package_of_linux_drivers-*.zip
190 After this step there should be two files in binary-tmp:
191 * Multimedia and Graphics library
192 > R-Car_Series_Evaluation_Software_Package_for_Linux-*.tar.gz
193 * Related Linux drivers
194 > R-Car_Series_Evaluation_Software_Package_of_Linux_Drivers-*.tar.gz
196 3. Copy the graphics acceleration drivers by shell script.
197 $ cd $AGL_TOP/meta-renesas/meta-rcar-gen2
198 $ ./copy_gfx_software_porter.sh ../../binary-tmp
200 4. Copy the multimedia acceleration drivers by shell script.
201 $ cd $AGL_TOP/meta-renesas/meta-rcar-gen2
202 $ ./copy_mm_software_lcb.sh ../../binary-tmp
204 #### Build from the Source code
206 You can build a R-Car2 M2 (porter) image using the following steps:
208 1. Export TEMPLATECONF to pick up correct configuration for the build
209 $ export TEMPLATECONF=$AGL_TOP/meta-renesas/meta-rcar-gen2/conf
211 2. Run the following command:
213 $ source poky/oe-init-build-env
215 Edit conf/bblayers.conf then remove this line.
216 ##OEROOT##/../meta-agl-demo \
218 (Optional) If you want to use multimedia accelerations, confirm your
219 conf/bblayer.conf has a entry of `meta-openembedded/meta-multimedia`
220 in BBLAYERS because packagegroup-rcar-gen2-multimedia needs some extra
223 3. (Optional) If you want to use multimedia accelerations, uncomment
224 manually 4 `IMAGE_INSTALL_append_porter` in conf/local.conf.
225 #IMAGE_INSTALL_append_porter = " \
226 # gstreamer1.0-plugins-bad-waylandsink \
229 #IMAGE_INSTALL_append_porter = " \
230 # gstreamer1.0-plugins-base-videorate \
234 #IMAGE_INSTALL_append_porter = " \
235 # libegl libegl-dev libgbm-dev \
239 #IMAGE_INSTALL_append_porter = " \
240 # packagegroup-rcar-gen2-multimedia \
244 Also it is needed to uncomment this,
245 #MACHINE_FEATURES_append = " multimedia"
247 This `multimedia` enables meta-renesas's multimedia configuration.
248 The version of GStreamer1.0 which AGL distro use, will be changed
249 to 1.2.3 (meta-renesas prefers) from 1.4.1(meta-agl default) by this switch.
251 4. Build the minimal image of AGL Distribution
252 $ bitbake agl-image-ivi
254 ### Deployment (SDCARD)
256 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).
258 #### Instructions on the host
260 1. Format SD-Card and then, create single EXT3 partition on it.
262 2. Mount the SD-Card, for example `/media/$SDCARD_LABEL`.
264 3. Copy AGL root file system onto the SD-Card
265 1. Go to build directory
266 $ cd $AGL_TOP/build/tmp/deploy/images/porter
267 2. Extract the root file system into the SD-Card
268 $ sudo tar --extract --numeric-owner --preserve-permissions --preserve-order \
269 --totals --directory=/media/$SDCARD_LABEL --file=agl-image-ivi-porter.tar.bz2
270 3. Copy kernel and DTB into the `/boot` of the SD-Card
271 $ sudo cp uImage uImage-r8a7791-porter.dtb /media/$SDCARD_LABEL/boot
273 4. After the copy finished, unmount SD-Card and insert it into the SD-Card slot of the porter board.
275 #### Instructions on the host
277 NOTE: There is details about porter board [here](http://elinux.org/R-Car/Boards/Porter).
279 NOTE: To boot weston on porter board, we need keyboard and mouse. (USB2.0 can be use for this)
281 ##### Change U-Boot parameters to boot from SD card
283 1. Power up the board and, using your preferred terminal emulator, stop the board's autoboot by hitting any key.
285 > Debug serial settings are 38400 8N1. Any standard terminal emulator program can be used.
287 2. Set the follow environment variables and save them
288 => setenv bootargs_console console=ttySC6,${baudrate}
289 => setenv bootargs_video vmalloc=384M video=HDMI-A-1:1024x768-32@60
290 => setenv bootcmd_sd 'ext4load mmc 0:1 0x40007fc0 boot/uImage;ext4load mmc 0:1 0x40f00000 boot/uImage-r8a7791-porter.dtb'
291 => setenv bootcmd 'setenv bootargs ${bootargs_console} ${bootargs_video} root=/dev/mmcblk0p1 rw rootfstype=ext3;run bootcmd_sd;bootm 0x40007fc0 - 0x40f00000'
294 ##### Boot from SD card
296 1. After board reset, U-Boot is started and after a countdown, ...
297 Linux boot message should be displayed. Please wait a moment.
298 2. Then weston is booted automatically, and weston-terminal appears.
302 4. (Optional) This is how to test and play multimedia contents with acceleration.
304 1. Boot porter without mouse and keyboard, it avoid to boot weston automatically.
305 For now, when running weston, V4L2 deosn't work correctly, so we have to
306 stop weston first (GST plugin `waylandsink` also doesn't work correctly for now).
308 2. Execute these instructions:
309 $ export LD_LIBRARY_PATH="/lib:/usr/lib:/usr/local/lib:"
312 $ amixer set "LINEOUT Mixer DACL" on
313 $ amixer set "DVC Out" 10
315 $ modprobe -a mmngr mmngrbuf s3ctl uvcs_cmn vspm fdpm
317 $ media-ctl -d /dev/media0 -r
318 $ media-ctl -d /dev/media0 -l '"vsp1.2 rpf.0":1 -> "vsp1.2 uds.0":0 [1]'
319 $ media-ctl -d /dev/media0 -l '"vsp1.2 uds.0":1 -> "vsp1.2 wpf.0":0 [1]'
320 $ media-ctl -d /dev/media0 -l '"vsp1.2 wpf.0":1 -> "vsp1.2 lif":0 [1]'
321 $ media-ctl -d /dev/media0 -V '"vsp1.2 rpf.0":0 [fmt:AYUV32/1920x1080]'
322 $ media-ctl -d /dev/media0 -V '"vsp1.2 rpf.0":1 [fmt:AYUV32/1920x1080]'
323 $ media-ctl -d /dev/media0 -V '"vsp1.2 uds.0":0 [fmt:AYUV32/1920x1080]'
324 $ media-ctl -d /dev/media0 -V '"vsp1.2 uds.0":1 [fmt:AYUV32/640x480]'
325 $ media-ctl -d /dev/media0 -V '"vsp1.2 wpf.0":0 [fmt:AYUV32/640x480]'
326 $ media-ctl -d /dev/media0 -V '"vsp1.2 wpf.0":1 [fmt:ARGB32/640x480]'
327 $ media-ctl -d /dev/media0 -V '"vsp1.2 lif":0 [fmt:ARGB32/640x480]'
329 # in caes R-Car M2 (HDMI - DU1 - vspd0)
330 $ modetest -M rcar-du -s 10@8:1280x720@AR24 -d -P '8@19:640x480+100+200@XR24' &
332 After these command, Test pattern will show on display connected to
335 Then, you can play H264(MP4) movie like these,
336 $ gst-launch-1.0 filesrc location=./sample.mp4 ! qtdemux name=d d. ! \
337 queue ! omxh264dec no-copy=true ! v4l2sink device=/dev/video1 \
