[Tinyos-host-mote-wg] [Tinyos-2.0wg] TinyOS 2.0 Pre-release 1

[Kristin Wright]

On behalf of the TinyOS 2.0 Working Group, I am pleased to announce
TinyOS 2.0 Pre-release 1.

TinyOS 2.0 has been designed by a  working group
( http://www.tinyos.net/scoop/special/working_group_tinyos_2-0 )
comprised of companies and institutions hailing from three continents.
 A primary 2.0 design goal was to maximize TinyOS' platform
portability,a goal that led to the adaption of the 2.0 Hardware
Abstraction Architecture (HAA). All of the TinyOS 2.0 design is
described in the TinyOS Extension Protocol (TEP) documents linked from
the TinyOS Working Group page (see link above).

TEP   2: Hardware Abstraction Architecture
TEP 101: ADC
TEP 102: Timers
TEP 103: Permanent Data 
TEP 104: Radio Physical Layer
TEP 105: Radio Link Layer
TEP 106: Schedulers and Tasks 
TEP 107: Boot Sequence
TEP 108: Resource Arbitration
TEP 109: Sensorboards

In addition to the design changes described in the above TEPs, 2.0
also includes infrastructure changes. The directory structure has been
modified to enhance platform portability and ease of use, and TinyOS
2.0 requires Tinyos-Tools 1.2 as well as NesC 1.2.

Note that there is little documentation in PreRelease1 other than the
TEPS above and has
limited functionality. Nevertheless, it is targeted at everyone from
early-adopters to the simply-curious who want to get a taste of what
is to come.

PreRelease1
------------------------------------------------------------------------------
PreRelease1 is a subset of what will become the full 2.0 release.
PreRelease1 includes platform support for mica2 and sample
applications built using a new TinyOS component architecture (OSKI).

Installation:
Please see http://www.tinyos.net/tinyos-2.x/doc/html/upgrade-tools.html 
for how to upgrade from a 1.x environment to a 2.x environment.
upgrade-tools.html also explains how to maintain  1.x and  2.x trees
simultaneously.

Known problems:
You might need to use the '--noscripts' option to uninstall
tinyos-tools. We have seen at least one case of the tinyos-tools rpm
hanging on uninstall. If rpm hangs after installing tinyos-tools,  you
can kill it with the task manager.

The CC1000 radio stack currently has some reliability problems; we
expect to address these in an upcoming 2.0 prerelease.
