  • 1. MeeGo on Development Boards Alison Chaiken alchaiken@gmail.com Nokia Mobility Solutions 5/24/2011
  • 2. Notable Dev Boards in use by aMeeGos BeagleBoard XM X1 Cortex A8 with SGX530 GPUPandaboardX2 Cortex A9 with SGX540 GPU ST-Ericsson Snowball X2 Cortex A9 with Mali GPU
  • 3. Prototyping possibilities Gumstix Overo X1 Cortex A8 with SGX530 GPUAtom N450 Mini-ITXSingle core, “integrated graphics” Variscite AM35 Freescale iMX53 QuickStart X1 Cortex A8 600 MHz, CAN bus X1 Cortex A8 1 GHz, SATA
  • 4. Different approaches● TI has put a great deal of effort into development hardware but less into SDK ● No TI “app store”● Intel has put great effort into the MeeGo SDK ● AppUp online store accepts “components” as well as user-facing apps● Gumstix is explicitly aimed at prototypers● ST Ericsson, Freescale just getting started
  • 5. Why does MeeGo care about dev boards?● Encourage interest in MeeGo platform − Education and science markets● Enable startups and small businesses to develop prototypes of H/W products● Ease development of H/W-intensive S/W (using sensors)● Potential to create accessory market of MeeGo-compatible devices
  • 6. Problems● Atom development boards are expensive ($1400) unless purchaser is part of “seed board” program ($149) ● Compatible tools (JTAG) also more expensive● MeeGo 1.2 ABI for ARM not backwards-compatible with 1.1 (softfp → hardfp break)● Device driver support spotty● Uneven toolchain support and documentation● Product lifetime and availability not always clear
  • 7. Questions Does MeeGo for Who are the current microcontrollers users and what are make sense? their plans? What features does MeeGo lack to support H/W that startups and small businesses need? What features do existingWhat relationship should dev boards lack? WhatMeeGo have with Yocto, Linaro, accessories?OpenEmbedded, Buildroot?
