Could you please check in the part which adds the new option and the <br>
code which opens the file.<br>

The TCP stream you saved with nc from the target consists of struct <br>
rtems_record_item_32. In the code above you read struct client_item <br>
items. This cannot be right. When you don't know which content a file <br>
has, please ask.<br></blockquote>typedef struct {<br> uint32_t event;<br> uint32_t data;<br><div>} rtems_record_item_32; </div><div><br></div><div>Okay. Raw file contents have this structure. It means raw file will only contain event and data in binary format. How should I get it's corresponding ns and cpu values.</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

You have to change this code here:<br>
<br>
while ( true ) {<br>
int buf[ 8192 ];<br>
ssize_t n;<br>
<br>
n = recv( fd, buf, sizeof( buf ), 0 );<br>
if ( n >= 0 ) {<br>
rtems_record_client_run( &ctx, buf, (size_t) n );<br>
} else {<br>
break;<br>
}<br>
}<br>
<br>
First you should refactor the code and move the TCP relates stuff into <br>
separate functions. </blockquote><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> </blockquote><div>The command line should like this right?</div><div>./build/misc/rtems-record --input=<file> | head </div></div><br clear="all"><div><br></div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><font size="4"><b>Ravindra Kumar Meena</b></font>,<div><span style="color:rgb(102,102,102)">B.
