+# Raspberry Pi Zero 2 W
+
+
+## Prerequisites
+
+* [extra2000/xilinx-toolkit v3.x image](https://github.com/extra2000/xilinx-toolkit)
+* SDCard with at least 4GB.
+* Digilent Analog Discovery 2 for accessing serial console through UART pins.
+
+
+## Building
+
+Allow source files to be mounted into container:
+```
+chcon -R -t container_file_t project
+```
+
+Create container:
+```
+podman run -it --rm \
+    --network=host \
+    --userns="keep-id:uid=1000,gid=1000" \
+    -v ${PWD}/project:${PWD}/project:rw \
+    --workdir ${PWD}/project/yocto/rpizero2-w \
+    --security-opt label=type:xilinx_toolkit_podman.process \
+    localhost/extra2000/xilinx-toolkit:latest \
+    bash
+source layers/poky/oe-init-build-env build
+```
+
+Check dependencies:
+```
+bitbake -p ros-core
+```
+
+Build:
+```
+bitbake ros-image-core
+```
+
+Flash to SD card:
+```
+bzcat project/yocto/rpizero2-w/build/tmp/deploy/images/raspberrypi0-2w-64/ros-image-core-humble-raspberrypi0-2w-64-*.rootfs.wic.bz2 | sudo dd bs=4M iflag=fullblock oflag=direct status=progress of=/dev/sdX; sudo sync
+```
+
+
+## Testing
+
+Insert SD card and power on Raspberry Pi Zero 2 W. Access serial console and login with `root` user. Then, follow [Testing](common/testing.md) instructions.
+
+
+## Cleaning Up
+
+To clean build:
+```
+rm -rf project/yocto/rpizero2-w/build/{sstate-cache,tmp}
+```
+
+
+## Known Issues
+
+When entering ROS2 environment using command:
+```
+source /etc/profile.d/ros/setup.bash
+```
+
+there will be errors such that:
+```
+Usage: head [OPTIONS] [FILE]...
+head: invalid option -- 'c'
+```

+# This file is your local configuration file and is where all local user settings
+# are placed. The comments in this file give some guide to the options a new user
+# to the system might want to change but pretty much any configuration option can
+# be set in this file. More adventurous users can look at local.conf.extended
+# which contains other examples of configuration which can be placed in this file
+# but new users likely won't need any of them initially.
+#
+# Lines starting with the '#' character are commented out and in some cases the
+# default values are provided as comments to show people example syntax. Enabling
+# the option is a question of removing the # character and making any change to the
+# variable as required.
+
+#
+# Machine Selection
+#
+# You need to select a specific machine to target the build with. There are a selection
+# of emulated machines available which can boot and run in the QEMU emulator:
+#
+#MACHINE ?= "qemuarm"
+#MACHINE ?= "qemuarm64"
+#MACHINE ?= "qemumips"
+#MACHINE ?= "qemumips64"
+#MACHINE ?= "qemuppc"
+#MACHINE ?= "qemux86"
+#MACHINE ?= "qemux86-64"
+#
+# There are also the following hardware board target machines included for
+# demonstration purposes:
+#
+#MACHINE ?= "beaglebone-yocto"
+#MACHINE ?= "genericx86"
+#MACHINE ?= "genericx86-64"
+#MACHINE ?= "edgerouter"
+#
+# This sets the default machine to be qemux86-64 if no other machine is selected:
+MACHINE ??= "raspberrypi0-2w-64"
+
+#
+# Where to place downloads
+#
+# During a first build the system will download many different source code tarballs
+# from various upstream projects. This can take a while, particularly if your network
+# connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
+# can preserve this directory to speed up this part of subsequent builds. This directory
+# is safe to share between multiple builds on the same machine too.
+#
+# The default is a downloads directory under TOPDIR which is the build directory.
+#
+#DL_DIR ?= "${TOPDIR}/downloads"
+
+#
+# Where to place shared-state files
+#
+# BitBake has the capability to accelerate builds based on previously built output.
+# This is done using "shared state" files which can be thought of as cache objects
+# and this option determines where those files are placed.
+#
+# You can wipe out TMPDIR leaving this directory intact and the build would regenerate
+# from these files if no changes were made to the configuration. If changes were made
+# to the configuration, only shared state files where the state was still valid would
+# be used (done using checksums).
+#
+# The default is a sstate-cache directory under TOPDIR.
+#
+#SSTATE_DIR ?= "${TOPDIR}/sstate-cache"
+
+#
+# Where to place the build output
+#
+# This option specifies where the bulk of the building work should be done and
+# where BitBake should place its temporary files and output. Keep in mind that
+# this includes the extraction and compilation of many applications and the toolchain
+# which can use Gigabytes of hard disk space.
+#
+# The default is a tmp directory under TOPDIR.
+#
+#TMPDIR = "${TOPDIR}/tmp"
+
+#
+# Default policy config
+#
+# The distribution setting controls which policy settings are used as defaults.
+# The default value is fine for general Yocto project use, at least initially.
+# Ultimately when creating custom policy, people will likely end up subclassing
+# these defaults.
+#
+DISTRO ?= "poky"
+# As an example of a subclass there is a "bleeding" edge policy configuration
+# where many versions are set to the absolute latest code from the upstream
+# source control systems. This is just mentioned here as an example, its not
+# useful to most new users.
+# DISTRO ?= "poky-bleeding"
+
+#
+# Package Management configuration
+#
+# This variable lists which packaging formats to enable. Multiple package backends
+# can be enabled at once and the first item listed in the variable will be used
+# to generate the root filesystems.
+# Options are:
+#  - 'package_deb' for debian style deb files
+#  - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
+#  - 'package_rpm' for rpm style packages
+# E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
+# We default to rpm:
+PACKAGE_CLASSES ?= "package_rpm"
+
+#
+# SDK target architecture
+#
+# This variable specifies the architecture to build SDK items for and means
+# you can build the SDK packages for architectures other than the machine you are
+# running the build on (i.e. building i686 packages on an x86_64 host).
+# Supported values are i686, x86_64, aarch64
+#SDKMACHINE ?= "i686"
+
+#
+# Extra image configuration defaults
+#
+# The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
+# images. Some of these options are added to certain image types automatically. The
+# variable can contain the following options:
+#  "dbg-pkgs"       - add -dbg packages for all installed packages
+#                     (adds symbol information for debugging/profiling)
+#  "src-pkgs"       - add -src packages for all installed packages
+#                     (adds source code for debugging)
+#  "dev-pkgs"       - add -dev packages for all installed packages
+#                     (useful if you want to develop against libs in the image)
+#  "ptest-pkgs"     - add -ptest packages for all ptest-enabled packages
+#                     (useful if you want to run the package test suites)
+#  "tools-sdk"      - add development tools (gcc, make, pkgconfig etc.)
+#  "tools-debug"    - add debugging tools (gdb, strace)
+#  "eclipse-debug"  - add Eclipse remote debugging support
+#  "tools-profile"  - add profiling tools (oprofile, lttng, valgrind)
+#  "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
+#  "debug-tweaks"   - make an image suitable for development
+#                     e.g. ssh root access has a blank password
+# There are other application targets that can be used here too, see
+# meta/classes/image.bbclass and meta/classes/core-image.bbclass for more details.

+#   - 'buildstats' collect build statistics
+USER_CLASSES ?= "buildstats"
+
+#
+# Runtime testing of images
+#
+# The build system can test booting virtual machine images under qemu (an emulator)
+# after any root filesystems are created and run tests against those images. It can also
+# run tests against any SDK that are built. To enable this uncomment these lines.
+# See classes/test{image,sdk}.bbclass for further details.

+#
+# Interactive shell configuration
+#
+# Under certain circumstances the system may need input from you and to do this it
+# can launch an interactive shell. It needs to do this since the build is
+# multithreaded and needs to be able to handle the case where more than one parallel
+# process may require the user's attention. The default is iterate over the available
+# terminal types to find one that works.
+#
+# Examples of the occasions this may happen are when resolving patches which cannot
+# be applied, to use the devshell or the kernel menuconfig
+#
+# Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none
+# Note: currently, Konsole support only works for KDE 3.x due to the way

+# shutdown the build. If there is less than 100MB or 1K inodes, perform a hard abort
+# of the build. The reason for this is that running completely out of space can corrupt

+# with very exotic errors.

+# used to accelerate build time. This variable can be used to configure the system
+# to search other mirror locations for these objects before it builds the data itself.
+#
+# This can be a filesystem directory, or a remote url such as http or ftp. These
+# would contain the sstate-cache results from previous builds (possibly from other
+# machines). This variable works like fetcher MIRRORS/PREMIRRORS and points to the
+# cache locations to check for the shared objects.
+# NOTE: if the mirror uses the same structure as SSTATE_DIR, you need to add PATH
+# at the end as shown in the examples below. This will be substituted with the

+
+#
+# Yocto Project SState Mirror
+#
+# The Yocto Project has prebuilt artefacts available for its releases, you can enable
+# use of these by uncommenting the following lines. This will mean the build uses
+# the network to check for artefacts at the start of builds, which does slow it down
+# equally, it will also speed up the builds by not having to build things if they are
+# present in the cache. It assumes you can download something faster than you can build it
+# which will depend on your network.
