Embedded Linux

In the world of embedded Operative Systems Linux is King so we decided to leave you a series of introductory guides to start with the most typical topics, like Device Tree, Kconfig, Bootloader configuration and device drivers

Part 0: An small Introduction

Welcome! This training is intended to provide you with the theoretical knowledge and practical experience necessary to navigate the world of embedded Linux development. By the end you should "know enough to

Part 1: Board bring-up

As part of the training, you were given a BeagleBone Black. We will be using this board to run all the labs, and also just to have fun with it. By the end

Part 2: Bootloader configuration

In the previous module we generated a cross-toolchain that allows us to compile programs for the BeagleBone Black. We did this (almost) from scratch, in tune with the spirit of this training. In

Part 3: Kernel configuration

In this module we will focus on replacing the kernel image currently used by the BeagleBoard Black with one generated by ourselves. We will start with a completely clean copy of the Linux

Part 4: Device drivers

In this module we will learn about device drivers, which is how Linux (as well as other kernels) handles peripheral devices. We will go through the different categories of devices, how applications interact

Part 5: Device Tree

In this module we will touch on the concept of device trees, a data structure used by some operating systems (Linux among them) to describe the hardware components of the computer in an

Part 6: Root filesystems

In the second module we established that a Linux-based system is composed of three main pieces: the bootloader, the kernel and the root filesystem. So far, we have studied the first two, focusing
