  1. Embracing Embedded Environments for Development Success By : Mark Recoskie

  2. Embedded Systems • Small • Special purpose • Solid state • Low power • Less expensive

  3. PC versus Embedded Device Embedded Device • embedded processor • small-med applications • low cost • little or no integration effort required • purpose built, solid state, more reliable • small in size • embedded development environment – different skill set required PC • x86 processor • small-med-large applications • greater cost • greater integration effort (cards & drivers, choosing components and building PC) • stigma – PC not as reliable as a proprietary PBX • large in size • familiar development environment

  4. Considerations • Processor • Memory • Cost of the unit • Special hardware integration • Software tools

  5. Development Differences • Why is development different? • Cross compile (Host  Target) • Different tools and libraries • Dependencies and packages • File systems • Optimizations • Debugging • Special skill set required

  6. “Building a gcc / glibc cross-toolchain for use in embedded systems development used to be a scary prospect, requiring iron will, days if not weeks of effort, lots of Unix and Gnu lore, and sometimes willingness to take dodgy shortcuts.” - Dan Kegel : a Google software engineer

  7. Embedded Development Environments • What are they? • Usually consist of a set of tools and framework • Installed on a independent computer • Most are a toolchain + Buildroot concept • Examples, • OpenWrt • PADS • Astfin • BAPS • AADK • Scripts

  8. Embedded Dev Suites (cont’d) • Various levels A) Toolchain (gcc, scripts, etc.) B) Buildroot concept (on top of toolchain) C) Buildroot+ (GUI, package manager) • Assembly line for code

  9. The Process • Automation is the word • 1) Selection • 2) Compilation • 3) Preparation • 4) Commitment • 5) Debugging

  10. The Process (cont’d)

  11. Benefits of Embedded Development Environments • Much less technical knowledge of an embedded environment is required • Much less setup time • Consistent and reproducible • Portable mechanism from machine to machine • Automation

  12. Summary • A good Embedded Development Environment is essential • Getting easier and easier to adopt • Embedded development is just different development – not harder
