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](http://lists.linuxfoundation.org/mailman/listinfo/automotive-discussions)

Packagegroups
-------------
AGL Demo Platform's package group design:
Top-level packagegroup,
> packagegroup-agl-appfw (all packages for demo platform)
This package group can contain sub-package groups like these.
> packagegroup-agl-appfw-graphics (for graphics subsystem)
> packagegroup-agl-appfw-agl (for AGL App Fw subystem)
> ...
The "packagegroups-agl-appfw-*" will contain packages for application and
frameworks.

Build a QEMU image
------------------
You can build a QEMU image using the following steps:

$ export TEMPLATECONF=/full/path/to/meta-agl-demo/conf
2. Run the following command:
$ source poky/oe-init-build-env
3. Build the full image of AGL Demo Platform and applications
$ bitbake agl-demo-platform
4. Run the emulator
$ cd $BUILD_DIR/tmp/deploy/images/qemex86-64
$ PATH_TO_POKY/poky/scripts/runqemu qemux86-64 bzImage-qemux86-64.bin \
agl-demo-platform-qemux86-64.ext3
For large screen:
$ PATH_TO_POKY/poky/scripts/runqemu qemux86-64 bzImage-qemux86-64.bin \
agl-demo-platform-qemux86-64.ext3 \
bootparams="uvesafb.mode_option=1280x720-32"
5. Some weston samples are available from weston terminal.
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 5f0d25152bac2d3798663a4ebfdd2df24060f153
$ cd -
$ git clone git://git.openembedded.org/meta-openembedded
$ cd meta-openembedded
$ git checkout 853dcfa0d618dc26bd27b3a1b49494b98d6eee97
$ cd -
$ git clone https://gerrit.automotivelinux.org/gerrit/AGL/meta-agl
$ cd meta-agl
$ git checkout 56eb51bfe05a1dd7c3c49cb7465ed83b0a072c78
$ cd -
$ git clone https://gerrit.automotivelinux.org/gerrit/AGL/meta-renesas
$ cd meta-renesas
$ git checkout c28172567a6325f5692e5d33b1ae1c1e64e59ddf
$ 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. Extract 2 tar archives
$ tar xf R-Car_Series_Evaluation_Software_Package_for_Linux-*.tar.gz
$ tar xf R-Car_Series_Evaluation_Software_Package_of_Linux_Drivers-*.tar.gz
4. Copy 2 files manually
1. Locate `EVA_r8a7791_linux_sgx_binaries_gles2.tar.bz2` in the Multimedia and Graphics library deliverable and copy it into the BSP layer.
$ cd $AGL_TOP
$ cp <path_to_file>/EVA_r8a7791_linux_sgx_binaries_gles2.tar.bz2 \
meta-renesas/meta-rcar-gen2/recipes-graphics/gles-module/\
gles-user-module/r8a7791_linux_sgx_binaries_gles2.tar.bz2
2. Locate `SGX_KM_M2.tar.bz2` in the related linux drivers deliverable and copy it into the BSP layer.
$ cp <path_to_file>SGX_KM_M2.tar.bz2 \
$ meta-renesas/meta-rcar-gen2/recipes-kernel/gles-module/gles-kernel-module
#### 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
3. 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](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-demo-platform-porter.tar.bz2
3. Copy kernel and DTB into the `/boot` of the SD-Card
$ sudo cp uImage uImage-r8a7791-porter.dtb /media/$SDCARD_LABEL
4. After the copy finished, unmount SD-Card and insert it into the SD-Card slot of the porter board.
#### Instructions on the host
NOTE: There is details about porter board [here](http://elinux.org/R-Car/Boards/Porter).
NOTE: To boot weston on porter board, we need keyboard and mouse. (USB2.0 can be use for this)
##### Change U-Boot parameters to boot from SD card
1. Power up the board and, using your preferred terminal emulator, stop the board's autoboot by hitting any key.
> Debug serial settings are 38400 8N1. Any standard terminal emulator program can be used.
2. Set the follow environment variables and save them
=> setenv bootargs_console console=ttySC6,${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! :)
