2. About this Talk
• Target Audience
– Developers creating Eclipse-based development
products
• Embedded Linux
• Desktop Linux
• Non-Linux OS running IP-based services
– Developers needing tools to support their workflow
– End-users who need VNC features in their workspace
• Scope
– High-level overview
– No code
– Juggling and trivia games at the end
3. Agenda
• Convergence
• What is the TmL project
• TmL technologies
• TmL in a commercial product
• Demonstrations
• The Future of TmL
• Working with the TmL project team
• The Strength of Community
• Q&A
4. con·ver·gence
kuh n-vur-juh ns - noun

7. Eclipse DSDP
• A top-level project of Eclipse.org operating according to
its charter, conducting regular meetings, and operating
transparently
• Sub-projects focused on the needs of device software,
led by prominent companies in mobile and embedded
– Motorola (Tools for Mobile Linux, Mobile Tools for Java)
– Wind River (Device Debugging*, Target Management)
– Texas Instruments (Real Time Software Components)
– IBM (eRCP*)
– Fujitsu (Native Application Builder)
– Genuitec (the project formerly known as Firefly)
• Project leads committed to working within Eclipse
Foundation policies and collaborating on joint efforts in
the spirit of open source
* Moved to other top-level projects
8. DSDP/TmL
• Incubated in December 2006, driven
largely by Motorola, with contributions
from Montavista and Nokia
• Two releases to date (Oct 2008, Jan 2009)
• Release 0.3 on Galileo train
• Commercial-quality code being used in
products available today
9. TmL - The Big Idea™
TmL
Tools
The objective of the
Tools for Mobile Linux Tools Frameworks
project is to help create
a development
environment that allow
Development
developers to easily Environment
create applications for
mobile Linux devices.
Application
Mobile Linux
Devices
10. More Than Mobile
While TmL is focused on
enabling mobile developers
targeting Linux, the tools
and frameworks can be
used by all developers and
end users
12. Device Framework
• A framework for defining the types of
devices that can be simulated and/or
communicated
• A mechanism for defining the states of
execution and the transitions between
those states
14. VNC Viewer Plug-in
• An implementation of the VNC protocol as
a View inside Eclipse
• Any OS that implements the Remote
Frame Buffer protocol over TCP/IP can be
targeted
16. Protocol Framework
• A framework that takes the definition of a
client-server communication protocol from
a number of extensions
• Executes the handshaking and sends and
receives messages according to protocol
specification
18. /proc tools
• Tools for accessing diagnostic information
available in the /proc pseudo filesystem
19. Device Proxy
• A framework for exchanging data between
external sources and simulated devices,
where external sources can be
represented by Eclipse Views
• Reference implementation of GPS
• Early in the development phase
21. Commercial Adoption of TmL
• Current
– MOTODEV Studio for Linux (2008)
– MOTODEV Studio for WebUI (2008, 2009)
– Future MOTODEV Studio products
• Future
– Montavista
– Nokia
– You?
22. Demonstrations
• VNC Viewer plugin in Eclipse Galileo
showing Puppy Linux
– QEMU (ARM Emulator)
• MOTODEV Studio for WebUI 1.0
– Ganymede SR1
– Motorola Linux (aka MOTOMAGX) on
VMware™
25. The future of TmL
• Continue development of frameworks, protocols and
reference implementations
• Continue on coordinated releases (trains)
• Support the Android development community
• Recruit contributors and committers from companies that
have interest in mobile & embedded Linux
• Move some technologies out of TmL that have better fit
in other projects
• Working with other Eclipse projects on common tools
needs for all Linux targets
• Eventual goal of reaching maturity (v 1.0)
