This page provides information related to building a custom Linux image (i.e “Linux From Scratch”) using individual open source components. The flow is documented through a series of sub-pages that take you step by step through the process of creating the software images and booting up a system.

Table of Contents

Introduction

Xilinx Open Source Linux is an open source project where key components are made available to users via two mechanisms:

1. The Xilinx Git contains U-Boot, ARM Trusted Firmware, Linux kernel, GDB, GCC, libraries and other system software

2. This Xilinx wiki contains documentation meant to guide the use of those software components

The software found in the Xilinx Git enables customers and partners with frequent updates to essential software, for inclusion within their own products, and development systems or tools.

Setting Up Your Development Environment

• Installing and Using Git
  Xilinx maintains a public Git tree for each of its open source projects.This page will give you the information you need to start using those trees.

• Installing the Xilinx Tools
  The installation includes the tools that are required to build your design, the Linux kernel and U-Boot.

• Zynq & ZU+ Emulation with QEMU
  Xilinx has created a Zynq & Zynq UltraScale+ MPSoC QEMU. Linux has been the primary test platform for QEMU. This page describes how to get started with QEMU quickly.

• Fetch Sources

• Build FSBL

• Build Device Tree Compiler (DTC)

• Build PMU Firmware

• Build Arm Trusted Firmware (ATF)

• Build U-Boot

• Build and Modify a Root File System

• Build Device Tree Blob

• Build Linux Kernel

• Prepare Boot Image

• Prepare Boot Medium

• Setup a Serial Console

• Additional Information: Build Qt and Qwt Libraries
