MASC/uCLinux On LEON3

Introduction

MicroController Linux (μCLinux) is a Linux operating system for embedded hardware systems without a memory management unit (MMU).

The LEON3 is a 32-bit VHDL processor core based on the SPARCV8 RISC instruction set architecture.

This project will involve synthesis and placement of a LEON3 processor onto a commercial off the shelf (COTS) field programmable gate array (FPGA), μCLinux will then be loaded to the FPGA.

System

• Ubuntu 8.10 running Sun VirtualBox Version 2.2.2 r46594.
• Virtual Machine running CentOS 5.3 i386, http://www.centos.org
• Download:
  • CentOS-5.3-i386-bin-1of6.iso

  • CentOS-5.3-i386-bin-3of6.iso
  • CentOS-5.3-i386-bin-4of6.iso

1. Obtain a desktop computer. Any desktop machine with a USB port, serial port, and internet connection should suffice. Install the host Operating System of Ubuntu 8.10, as well as the specified VirtualBox.
2. Download the CentOS distribution, specific .iso file listed above.
3. In VirtualBox, create a new virtual machine. Specific options used are described in CentOS_5.3_i366.xml.
4. When installing CentOS, install the following extras: "Development Libraries","Development Tools","Java Development","Legacy Software Development"
5. Login-name: 'centos' sans single quotes.
6. Once CentOS is installed: a. Applications->System Tools->Software Updater
7. We know have a fresh, updated operating system to begin the project.
