?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.

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=ext4;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! :)
### 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! :)
