Introduction

Embedded Linux development for any single board computer (SBC) or embedded development board typically involves integration of -

• Kernel
• Boot loader
• System libraries and
• Third party applications (if needed).

Before chosing to develop the Embedded Linux system, make sure there is Linux and open source boot loader like U-boot support for SoC.

Requirements

The following hardware required to develop an Embedde Linux system.

• Raspberry Pi Model B
• A laptop / desktop with Ubuntu Linux
• An HDMI cable
• A HDMI capable monitor or TV
• An USB keybord
• A good broadband connection

Why Raspberry Pi

Raspberry Pi has extensive Linux and U-boot support. There are official Linux distributions from Debian, Ubuntu and others. Learning and developing is easy when there is quite a large community of developers and tinkerers to get help.

Learning path

Consider following list of articles as a table of contents or the overview of the learning path.

• Building a cross toolchain
• Cross compiling U-boot bootloader
• The boot sequence
• Setting up Ethernet communication
• Cross-compile and load Linux kernel
• Generating minimal file system with busybox
• Install Linux kernel modules in busybox filesystem
• Network boot your Raspberry Pi 3B
• System configuration and startup
