 AGL has been initially ported to Raspberry Pi 2 and 3 by Leon Anavi thanks to the existing knowledge for enabling hardware graphics acceleration in Wayland and Weston from the Tizen Project and GENIVI Development Platform.

+Follow the [[agl-distro:source-code|general steps for building AGL]], download master branch and set **raspberrypi4** (recommended) or **raspberrypi3** as a machine depending on the version and the model of your Raspberry Pi. Support for Raspberry Pi 2 has been deprecated in the latest AGL releases.
+====== Introduction: Building target AGL image with Yocto project ======
+The standard Yocto process is made of the following steps:
+  * Setting up your operating system.
+  * Setting up the build environment for R-Car BSP.
+  * Downloading the proprietary drivers and installing them in the build environment (if needed).
+  * Build the image.
+  * Boot using SD-CARD.
+    * Create an SD-CARD.
+    * Configure to boot on SD-CARD.
+    * Copy the image to the SD-CARD.
+    * Boot the board on it.
+For convenience, the resulting development images are made available [[https://download.automotivelinux.org/AGL/snapshots/master/latest/|Here]]
+If you want to bypass the build phase and quick boot the board, you can download the image tarball and the kernel then follow the installation procedure.
+===== Setting up your operating system =====
+The very first step is to ensure that your system can run the build system of the Yocto Project.
+**Important**: it only runs on Linux
+  * if your system is Windows© or iOS© you should use a virtualization solution (Virtualbox, VMWare ...) to run a Linux VM on your system.
+For AGL 2.1, Yocto Project 2.1, known as krogoth, has been selected for the BSP and build system.
+Reference data for configuring your system can be found in the Yocto documentation [[http://www.yoctoproject.org/docs/2.0/ref-manual/ref-manual.html#detailed-supported-distros|Here]]
+Here after an extract of this documentation for most common Linux distributions:
+  * The build system should be able to run on any modern distributions that has the following versions for:
+    * Python
+    * Git 1.7.8 or greater
+    * tar 1.24 or greater
+    * GCC, …
+=== Note: ===
+  * Python 2.7.3 or greater excluding Python 3.x, which is not supported.
+==== Ubuntu and Debian ====
+The essential and graphical support packages you need for a supported Ubuntu or Debian distribution are shown in the following command:
+<code>
+sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
+     build-essential chrpath socat libsdl1.2-dev xterm cpio curl
+</code>
+=== Note: ===
+  * Also note that for this tutorial, the utility 'curl' has been added to the list of packages to install.
+==== Fedora ====
+The essential and graphical packages you need for a supported Fedora distribution are shown in the following command:
+<code>
+sudo yum install gawk make wget tar bzip2 gzip python unzip perl patch \
+     diffutils diffstat git cpp gcc gcc-c++ glibc-devel texinfo chrpath \
+     ccache perl-Data-Dumper perl-Text-ParseWords perl-Thread-Queue socat \
+     SDL-devel xterm curl
+</code>
+==== OpenSUSE ====
+The essential and graphical packages you need for a supported OpenSUSE distribution are shown in the following command:
+<code>
+sudo zypper install python gcc gcc-c++ git chrpath make wget python-xml \
+     diffstat texinfo python-curses patch socat libSDL-devel xterm curl
+</code>
+==== CentOS ====
+The essential and graphical packages you need for a supported CentOS distribution are shown in the following command:

+===== Setting up the build environment =====
+In the following, your top level directory is noted as “AGL_TOP”.\\
+For example, we will set AGL_TOP to point to a directory “$HOME/workspace_agl”:
+<code>
+export AGL_TOP=$HOME/workspace_agl
+mkdir -p $AGL_TOP
+</code>
 ===== Prepare Repo Tool =====
-AGL Uses the Repo tool for managing repositories. First you need to setup layers of AGL. You can use the commands below to prepare Repo:

 ====== Troubleshooting ======
-Due to a known bug in the upstream of meta-rust the Yocto/OE recipe for rust-cross may fail while building RVI SOTA Client or another application written in the Rust programming language. Until the complete resolution of the issue the workaround is to disable all use of the CXX11 ABI by applying the following lines to **conf/local.conf**:
+===== Extended attributes MUST be copied =====
+**IMPORTANT, The extended attribute set during image construction MUST be copied to the SD card.**
+When using tar to create the SDcard, it is a common error to not copy the extended attributes. Find below instruction for using tar.
+Verify that **tar** version is 1.28 or newer:
+<code>
+tar --version
+tar (GNU tar) 1.28
+[snip]
+</code>
+If it is not the case, a native up-to-date version of tar is also generated while building AGL distribution:
+<code>
+tmp/sysroots/x86_64-linux/usr/bin/tar-native/tar --version
+tar (GNU tar) 1.28
+[snip]
+</code>
+To copy Automotive Grade Linux (AGL) files AND EXTENDED ATRIBUTES onto the SDcard using tar the command is:
+<code>
+tar --extract --numeric-owner --preserve-permissions --preserve-order --totals \
+           --xattrs-include='*' --directory=DESTINATION_DIRECTORY --file=agl-demo-platform.....tar.bz2

+===== Disabling Homescreen in AGL 3.0.x CC release =====
+**Problem**: new installed applications are not available on Homescreen and even if started manually through afm-util, the application starts but no surface appears.
+**Answer**: this is due to IVI-Shell integration with Qt and Homescreen.
+To disable IVI-Shell and revert to the "plain old" weston desktop, you can follow the 4 steps below:
+  * Modify ///etc/xdg/weston/weston.ini// and comment the line mentioning IVI-shell. For example on Porter board:
+<code>
+           [core]
+           backend=drm-backend.so
+           #shell=ivi-shell.so
+           ...
+</code>
+  * modify ///usr/lib/systemd/user/afm-user-daemon.service// and comment the line specifying QT Wayland backend:
+<code>
+           ...
+           #Environment=QT_WAYLAND_SHELL_INTEGRATION=ivi-shell
+           ...
+</code>
+  * disable Homescreen services:
+<code>
+           # systemctl disable HomeScreenAppFrameworkBinderAGL.service
+           # systemctl disable HomeScreen.service
+           # systemctl disable InputEventManager.service
+           # systemctl disable WindowManager.service
+</code>
+  * Reboot your target and you should then be able to start apps on the standard weston screen using afm-util
