<p>Release consists of the RTOS sources and three sample projects - see
<a class="reference" href="../index.html">Release description</a> for details. Each sample located in separate
folder. Structure of test project folder (folders are in brackets '[]'):</p>
<pre class="literal-block">
[Config] - linker scripts and other utilities
[Exe] - executable product[s]
[List] - listings and other temporary text files
[Obj] - objects and other intermediate files
[settings] - IAR IDE auxiliary files
[Src] - test project sources
slon.ewd - IAR IDE auxiliary file
slon.ewp - IAR IDE project
slon.eww - IAR IDE workspace
</pre>
<p><strong>slon</strong> is test project name.</p>
<p>Structure of the RTOS folder:</p>
<pre class="literal-block">
scmRTOS

<p>There is only one way provided to build any sample - <strong>IAR IDE</strong>.</p>
<p>Just launch IDE, open appropriate workspace (*.eww file), choose project target (RAM/Flash),
and build the project.
Default chip type, the sample project is targeted for is AT91SAM7S64. To alter chip type, three
settings has to be changed:</p>
<ol class="arabic simple">
<li>Project->Options->General Options->Target->Device</li>
<li>Project->Options->C/C++ Compiler->Preprocessor->Defined symbols (consult device.h for appropriate value)</li>
<li>Project->Options->Assembler->Preprocessor->Defined symbols (consult device.h for appropriate value)</li>
</ol>
<p>If user want to use his own build system <a class="footnote-reference" href="#id3" id="id2" name="id2">[1]</a> he has to specify the following
command-line options for various tools:</p>

<p>This release supports all AT91SAM7 devices, supported by version 4.30 of IAR EWARM. If user
has modern version of compiler and wants to use other AT91SAM7 family device, two files has to be
changed: <tt class="docutils literal"><span class="pre">device.h</span></tt> in Src folder and <tt class="docutils literal"><span class="pre">OS_Target_core.h</span></tt> in scmRTOS/ARM7 folder. Contence of those
files is simple enought.</p>
