toolchain

''' A toolchain refers to a collection of software tools that are used to build and compile software for a specific target platform. This collection typically includes a compiler, linker, assembler, debugger, and other utilities necessary for software development.

In the context of embedded systems and cross-compilation, a toolchain is crucial because it allows developers to compile code on one architecture (like a PC) for another architecture (like an ARM-based embedded device). This is often necessary in embedded systems development, where the target device may not have the resources or capabilities to compile software directly on itself. '''

Crosstool-NG

''' Crosstool-NG is a popular open-source tool that helps in building cross-compilation toolchains. It's designed to simplify the process of creating toolchains for various target architectures, making it easier for developers working on embedded systems or cross-platform projects. '''

Crosstool-NG

$ git clone https://github.com/crosstool-ng/crosstool-ng.git
$ cd crosstool-ng
$ git checkout crosstool-ng-1.25.0

Run bootstrap to setup the environment

$ ./bootstrap

Run configure to check all dependency

$ ./configure --enable-local

make to generate the Makefile for croostool-ng

$ make  

ct-ng list-samples to list all microcontrollers supported

./ct-ng list-samples | grep [microcontroller]

ct-ng to configure the microcontroller used

./ct-ng [microcontroller]

ct-ng menuconfig to configure toolchain

./ct-ng menuconfig

ct-ng build to build and get your toolchain

./ct-ng build

After build
