Buildroot
Buildroot is a set of Makefiles and Patch (Unix), patches that simplifies and automates the process of building a complete and bootable Linux environment for an embedded system, while using Cross compiler, cross-compilation to allow building for multiple target platforms on a single Linux-based development system. Buildroot can automatically build the required cross-compilation toolchain, create a root file system, compile a Linux kernel image, and generate a boot loader for the targeted embedded system, or it can perform any independent combination of these steps. For example, an already installed cross-compilation toolchain can be used independently, while Buildroot only creates the root file system. Buildroot is primarily intended to be used with small or embedded systems based on various computer architectures and instruction set architectures (ISAs), including x86, ARM architecture, ARM, MIPS architecture, MIPS, PowerPC and RISC-V. Numerous architectures and their variants a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Embedded Operating System
An embedded operating system (EOS) is an operating system designed specifically for embedded computer systems. These systems aim to enhance functionality and reliability to perform dedicated tasks. When the multitasking method employed allows for timely task execution, such an OS may qualify as a real-time operating system (RTOS). Overview Embedded operating systems are integral to consumer electronics such as cameras and mobile phones. Additionally, they power automotive electronics, aiding in functions like cruise control and navigation. Moreover, they are essential for factory automation infrastructure. Everyday applications of EOS include office automation devices such as image scanners, photocopiers, and wireless access points. Home automation systems, including security systems, also depend on EOS. Design Embedded systems comprise a processor and corresponding software.

Toolchain
A toolchain is a set of software development tools used to build and otherwise develop software. Often, the tools are executed sequentially and form a pipeline such that the output of one tool is the input for the next. Sometimes the term is used for a set of related tools that are not necessarily executed sequentially. A relatively common and simple toolchain consists of the tools to build for a particular operating system (OS) and CPU architecture; consisting of a compiler, a linker, and a debugger. With a cross-compiler, a toolchain can support cross-platform development. For building more complex software systems, many other tools may be in the toolchain. For example, for a video game, the toolchain may include tools for preparing sound effects, music, textures, 3-dimensional models and animation Animation is a filmmaking technique whereby still images are manipulated to create moving images. In traditional animation, images are drawn or painted by hand on tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Make (software)
In software development, Make is a command-line interface software tool that performs actions ordered by configured dependencies as defined in a configuration file called a ''makefile''. It is commonly used for build automation to build executable code (such as a program or library) from source code. But, not limited to building, Make can perform any operation available via the operating system shell. Make is widely used, especially in Unix and Unix-like operating systems, even though many competing technologies and tools are available, including similar tools that perform actions based on dependencies, some compilers and interactively via an integrated development environment. In addition to referring to the original Unix tool, Make is also a technology since multiple tools have been implemented with roughly the same functionality including similar makefile syntax and semantics. Origin Stuart Feldman created Make while at Bell Labs. An early version was completed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
