Converter Tool Tutorial</title><shortdesc>This topic describes the Central Repository Converter (<codeph>CenRepConv</codeph>)

<section id="GUID-D103CC8D-6871-46D1-B41E-85F5632324DC"><title>Overview</title> <p>The <codeph>CenRepConv</codeph> is an
emulator based tool. The <codeph>CenRepConv</codeph> tool can be used to convert
binary files to text files for debugging. The central repository initialisation
files are used to register the repositories with central repository. The initialisation
files can be either in text or binary format, although binary format is recommended
for better efficiency. For example, the loading time of a repository with
2000 settings on a H2 development board is 41ms for binary files and 485ms
for text files. </p> <p>The tool uses the file extension to identify the fomats. <codeph>TXT</codeph> is
used for the text file extension and <codeph>CRE</codeph> is used as the binary
file extension </p> </section>

<li id="GUID-DE6793EF-7069-55AD-AEF2-5EFED65BD209"><p> <codeph>output_path</codeph> –
Optional, default is <codeph>C:\</codeph>. Note that if the user specifies
the output filename, then the extension must be .cre and the filename must
match the &lt;repository_uid&gt; of the input file. </p> </li>
<li id="GUID-AA6CB0CD-8931-588F-B27A-E7EC60576B5D"><p> <codeph> -nowait</codeph> option
should be used when CentRepConv is invoked as part of an automated process
such as from a build script. It instructs CentRepConv not to wait for user
acknowledgement. Without this option the tool will wait for up to 30 seconds
for acknowledgement </p> </li>
