Introduction to Toolchains in Embedded Systems
Usually toolchains are used in the embedded world for cross-compiling, which means creating a program on a host which will eventually run on a different kind of target – therefore there is a need to create it with a specific compiler, linker, debugger etc.
Understanding Toolchains in Maven
A Toolchain is a preconfigured object that Maven plugins can use for tool configuration retrieval (location and other information). With jdk toolchain, for example, instead of being stuck with the JDK used to run Maven, all plugins can use the same other JDK instance without hardcoding absolute paths into the pom.
Overview of GNU Toolchain in Linux
The GNU Toolchain is a set of programming tools in Linux systems that programmers can use to make and compile their code to produce a program or library. The toolchain contains GNU m4, GNU Make, GNU Bison, GCC, GNU Binutils, GNU Debugger and the GNU build system. Let’s understand these tools one by one in detail.
Object-Oriented Concepts in Programming
What does "none Eabi" mean? arm-none-eabi is the toolchain we use in this class. This toolchain targets the ARM architecture, has no vendor, does not target an operating system (i.e. targets a "bare metal" system), and complies with the ARM EABI.
How do you call a class? To call a class method, put the class as the first argument. Class methods can be can be called from instances and from the class itself. All of these use the same method. The method can use the classes variables and methods.
What is an object in Java? A Java object is a member (also called an instance) of a Java class. Each object has an identity, a behavior, and a state. The state of an object is stored in fields (variables), while methods (functions) display the object’s behavior. Objects are created at runtime from templates, which are also known as classes.
