Embedding Linux in an EPROM

Nov 4, 1999 — by LinuxDevices Staff — from the LinuxDevices Archive — 2 views

Introduction

This article describes one way to run Linux in an embedded system with no hard disk. The application I describe is an Operator Interface in a monitor and display system developed by Boeing Flight Test. The airborne environment requires something fairly rugged, and must withstand common power interruptions. To meet these requirements we decided to build the operator interface without a hard disk.

Overview

The basic concept used is to boot from a solid state disk (SSD) in EPROM, copy a root file system from EPROM to a ram disk, load the operator interface software from a host and run. This article focuses on the details of how the system works, and on development techniques used.
