The following installation steps assume a clean platform build.  Modifying
the installation paths or relying on existing cygwin installations may require
updating paths and environment variables, neither of which are covered here.

In order to build and install executables for the Imote platform, you need to
download and install the following pieces of code.  Details on each are
provided below.

    - TinyOS v1.1.7
    - NesC v1.1.2
    - Imote platform v1.1.7
    - Gnu gcc cross compiler v3.2
    - ADS tool chain v1.2


TinyOS v1.1.7
  While the imote platform will work with most versions of TinyOS, the current
  release has been specifically tested using version 1.1.7.  If you have an
  older version of TinyOS please upgrade before installing the Imote platform
  code.  TinyOS v1.1.7 can be obtained from sourceforge or the TinyOS web site
  at http://www.tinyos.net/download.html

  Follow the install instructions on the web site to install TinyOS


NesC v1.1.2
  NesC v1.1.2 extends the multi-platform support using the .platform file.
  This is required for the imote platform to properly compile and load its
  executables.  If you have an older version of NesC, please upgrade to v1.1.2
  The NesC upgrade is available via rpm.  You can down load the rpm from:

  http://www.tinyos.net/dist-1.1.0/tinyos/windows/nesc-1.1.2a-1.cygwin.i386.rpm

  Once you have the rpm, you can install it by switching to the download
  directory in a cygwin window and executing the following command:

  $ rpm -Uvh nesc-1.1.2a-1.cygwin.i386.rpm


Imote platform v1.1.7
  The imote platform is available from two sources, sourceforge or the TinyOS
  web site.  Sourceforge will contain the latest released CVS tree, and the
  TinyOS web site has a rpm for a recent release.  There have been access
  problems when using sourceforge's CVS repository from behind a firewall so
  cvs updates may not be possible from some locations.  The two methods for
  obtaining the imote platform code are described below:


  Method 1 - CVS from Sourceforge
    You need to get two directory trees from Sourceforge.  Change directories to
    the root of your TinyOS tree.  If you've followed the instructions to this
    point that should be in /opt/tinyos-1.x

    From the root, execute the following two commands:
  
    $ cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/tinyos co tinyos-1.x/beta/platform/imote

    $ cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/tinyos co tinyos-1.x/contrib/imote


  Method 2 - RPM from TinyOS web site
    Download the contrib-imote rpm from the TinyOS web site.  Change to the
    download directory and execute the following command:

    http://www.tinyos.net/related/contrib-imote-1.1.7-1.cygwin.i386.rpm

    $ rpm -ivh contrib-imote-1.1.7-1.cygwin.i386.rpm

    This will install both the .../contrib/imote and .../beta/platform/imote
    trees.

  Note that the beta/platform/imote directory is similar to the tos/platform/*
  directories in that it contains the platform specific code.


Gnu gcc cross compiler v3.2
  The gcc cross compiler used by NesC is available via rpm on the TinyOS web
  site at 

    http://www.tinyos.net/dist-1.1.0/tools/windows/arm-thumb-elf-gcc-3.2-1.cygwin.i386.rpm

  This rpm contains the 3.2 version of gcc available from the gnu web
  site configured to build an ARM executable on a x86 platform.  After you
  have downloaded the rpm, change directories to the download directory and
  execute the following command:

  $ rpm -ivh arm-thumb-elf-gcc-3.2-1.cygwin.i386.rpm


ADS tool chain v1.2
  The final step of the build process requires use of the ADS tool chain's
  linker.  A CD containing the ADS tool chain is available from the arm web
  site at www.arm.com

  Follow the directions for installing the ADS tool chain.

You are now ready to build and install an imote executable.  Change directories
to /opt/tinyos/contrib/imote/apps/Blink and execute the following command:

make install imote

This should build an imote executable which blinks the red LED at 1 second
intervals.
