?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.

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! :)
