Introduction to Yocto
• Yocto Project (https://www.yoctoproject.org/ )
 Open-source embedded Linux build system
 “It's not an embedded Linux distribution – it creates a custom one for you”
 Freescale – Yocto contributor
 Freescale SDK – Yocto based (Power Architecture® and ARM® technologies)
Yocto provides and integrated build environment
• User-friendly framework for creating Linux distribution
• Configure the target
• Build the toolchain: GCC, GCC-cross egblic, binutils
• Build the u-boot, kernel
• Build Linux User space applications

Application Development Toolkit (ADT)
• Yocto Project provides ADT tools
• Objective: provides a user-friendly way to build and develop
complete software stack
• ADT consists of the following:
− Architecture specific cross-toolchain
− QEMU
− User space tools
− Eclipse IDE Yocto Plug-in
• ADT can be used:
− Extending an Yocto build directory
• Yocto provides: cross-toolchain, QEMU and User space tools
− Stand alone (using ADT installer script)

ADT - Resources
− Yocto Project resources
− ADT Overview
• https://www.yoctoproject.org/tools-resources/projects/application-development-toolkit-adt
− ADT Manual
• https://www.yoctoproject.org/docs/current/adt-manual/adt-manual.html

Building Yocto
• Install Freescale Yocto SDK QorIQ-SDK-V1.5
• Configure build environment
$ source ./oe-init-build-env
• Build toolchain and root file system. Install toolchain
$ bitbake meta-toolchain
$ bitbake core-image-sato-sdk
$ cd tmp/deploy/sdk && source ./poky-eglibc-*.sh
• Gernerate qemu Rootfs
$ runqemu-extract-sdk <rootfs.tar.bz2> <destination>
• Yocto build provides:
− Complete distribution for target (linux, user space tools)
− Cross-toolchain
− QEMU
