+ The Cross-Development Toolchain + + + The + Cross-Development Toolchain + consists of a cross-compiler, cross-linker, and cross-debugger + that are used to develop user-space applications for targeted + hardware. + This toolchain is created either by running the ADT Installer + script, a toolchain installer script, or through a + Build Directory + that is based on your Metadata configuration or extension for + your targeted device. + The cross-toolchain works with a matching target sysroot. + +
+ +
+ Sysroot + + + The matching target sysroot contains needed headers and libraries for generating + binaries that run on the target architecture. + The sysroot is based on the target root filesystem image that is built by + the OpenEmbedded build system and uses the same Metadata configuration + used to build the cross-toolchain. + +
+ +
+ Eclipse Yocto Plug-in + + + The Eclipse IDE is a popular development environment and it fully supports + development using the Yocto Project. + When you install and configure the Eclipse Yocto Project Plug-in into + the Eclipse IDE, you maximize your Yocto Project experience. + Installing and configuring the Plug-in results in an environment that + has extensions specifically designed to let you more easily develop software. + These extensions allow for cross-compilation, deployment, and execution of + your output into a QEMU emulation session. + You can also perform cross-debugging and profiling. + The environment also supports a suite of tools that allows you to perform + remote profiling, tracing, collection of power data, collection of + latency data, and collection of performance data. + + + + For information about the application development workflow that uses the Eclipse + IDE and for a detailed example of how to install and configure the Eclipse + Yocto Project Plug-in, see the + "Working Within Eclipse" section + of the Yocto Project Development Manual. + +
+ +
+ The QEMU Emulator + + + The QEMU emulator allows you to simulate your hardware while running your + application or image. + QEMU is made available a number of ways: + + + If you use the ADT Installer script to install ADT, you can + specify whether or not to install QEMU. + + + If you have cloned the poky Git + repository to create a + Source Directory + and you have sourced the environment setup script, QEMU is + installed and automatically available. + + + If you have downloaded a Yocto Project release and unpacked + it to create a + Source Directory + and you have sourced the environment setup script, QEMU is + installed and automatically available. + + + If you have installed the cross-toolchain tarball and you + have sourced the toolchain's setup environment script, QEMU + is also installed and automatically available. + + + +
+ +
+ User-Space Tools + + + User-space tools are included as part of the distribution. + You will find these tools helpful during development. + The tools include LatencyTOP, PowerTOP, OProfile, Perf, SystemTap, and Lttng-ust. + These tools are common development tools for the Linux platform. + + LatencyTOP: LatencyTOP focuses on latency + that causes skips in audio, + stutters in your desktop experience, or situations that overload your server + even when you have plenty of CPU power left. + + PowerTOP: Helps you determine what + software is using the most power. + You can find out more about PowerTOP at + . + OProfile: A system-wide profiler for Linux + systems that is capable of profiling all running code at low overhead. + You can find out more about OProfile at + . + For examples on how to setup and use this tool, see the + "OProfile" + section in the Yocto Project Profiling and Tracing Manual. + + Perf: Performance counters for Linux used + to keep track of certain types of hardware and software events. + For more information on these types of counters see + . + For examples on how to setup and use this tool, see the + "perf" + section in the Yocto Project Profiling and Tracing Manual. + + SystemTap: A free software infrastructure + that simplifies information gathering about a running Linux system. + This information helps you diagnose performance or functional problems. + SystemTap is not available as a user-space tool through the Eclipse IDE Yocto Plug-in. + See for more information + on SystemTap. + For examples on how to setup and use this tool, see the + "SystemTap" + section in the Yocto Project Profiling and Tracing Manual. + Lttng-ust: A User-space Tracer designed to + provide detailed information on user-space activity. + See for more information on Lttng-ust. + + + +
