Eclipse History and Overview

• Donated by IBM to open source community in NOV
  2001
• An open development platform and a community
• Multi-platform GUI for anything and nothing in
  particular
• Java plug-in architecture
• Governed by Eclipse Public License (EPL)
• Initially implemented as a Java integrated
  development environment (JDT)
• Eclipse foundation formed in JAN 2004
• Many language and software development focused
  plug-ins and environments
• Major sub-projects coordinated releases every
  June

Eclipse has grown up!

Key Eclipse Projects for embedded

• CDT C/C Development Toolkit
• C/C source code editor and indexer
• Syntax highlighting and object browsing
• Build management
• Binary parsing
• Native support for GCC/GDB
• RSE Remote Systems Explorer
• Consistent interface across multiple targets
• Many connection mechanisms
• Filesystem management
• Process management
• Shell (and terminal) access

6
Installing and Updating Eclipse

• eclipse.org/downloads
• Updating and finding plug-ins

7
Step 1 Setting up a Target

• Install RSE plugin
• Setup SSH server on target
• Open Remote Systems Explorer Perspective
• Create SSH Only RSE connection
• Open integrated shell on target
• Perform file management tasks on target

8
Step 2 Building an application

• Open C/C Perspective
• Create new Managed Make C project
• Open build setting and preface compiler command
  line name with architecture name
• i.e. armv6_gcc
• Build application

9
Step 3 Deploying an application

• Open RSE perspective
• Drag-and-drop binary from Local system to target
• Open integrated remote shell
• Run application from shell

10
Step 4 Debugging an application

• Setup launch configuration (Run Run)
• Select target connection (exported by RSE)
• Login to target through shell
• Start gdbserver on target
• Specify gdb remote connection and port in
  .gdbinit
• Open Debug Perspective
• Debug application

Working Examples

• MontaVista DevRocket 5.0
• Edit-Compile-Debug automation
• Application Analysis
• Memory Usage Analysis
• Memory Leak Detection
• Performance Profiling
• System Analysis
• Performance Profiling
• Trace Visualization
• Filesystem Creation

12
Future (interesting) Initiatives

• DSDP Device Software Development Project
• Umbrella project focused on improving embedded
  development
• RTSC Realtime System Components
• TI led project to support DSPs and 16-bit
  microcontrollers
• TCF - Target Communications Framework
• One protocol to rule them all
• Debugging, monitoring, analysis, and test tools
• DD - Device Debugging
• Extensible Debugger Services Framework for better
  integration

13
Summary

• Eclipse is quickly becoming the de-facto standard
  for embedded Linux Integrated Development
  Environments
• CDT is mature enough (now) to support
  cross-compilation and debugging and to handle
  larger projects
• RSE makes target management easy
• Embedded focused features and integration is
  improving all the time
• Its time to give it a try!
