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)

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

Eclipse IDE Yocto Plug-in Overview
• Eclipse IDE Yocto plug-in is provided by Yocto Project• Eclipse user friendly environment that enables GUI access to ADT
and Yocto resources− Cross compilation− Development, execution and debug− Advanced Linux tools support (oprofile, perf, lttng)− Linux application development support, including autotools− Integrated QEMU support− Yocto specific configuration (Yocto build directory and metadata parsing)− Support for standalone and Yocto build system support− User friendly interface for creating a new Yocto Project BSP

TM
External Use 10
Embedded Linux Application Development (1)
• Create the project• Start QEMU simulator• Configure debug settings• Debug and other tools (perf)
TM
External Use 11
Embedded Linux Application Development (2)
Create the project• New Project -> C/C++/ C Project
− Yocto Project ADT Autotools− Yocto Project ADT CMake
• Inherit all Yocto configurations− Toolchain− Build flags (-mcpu, -m32…)− sysroot
TM
External Use 12
Embedded Linux Application Development (3)
Launch QEMU• Run->External Tools -> External Tools Configurations
− qemu <ppc603e> executable automatically added by Yocto Plugin− Qemu inherits all the configurations from Yoct (settings, scripts)
TM
External Use 13
Embedded Linux Application Development (4)
Configure Debug Settings• Debug Configurations -> C/C++ Remote Application
− Application elf− Connection to target (qemu) New Connection
• Select TCF protocol for connection to target• Set IP address of the qemu• Browse target (qemu) capabilities
− Debugger cross gdb from yocto :
/opt/poky/1.4.1/sysroots/…/powerpc-poky-linux-gdb
TM
External Use 14
Embedded Linux Application Development (5)
Debug and other tools• gdb based debug• Debug application on qemu• Enable other tools
− Perf− Oprofile− Lttng− System Tap
• Root console for running
other tools (perf)
TM
