    <p>Pu,</p>
    <p>  If the *.idf file has errors in it then TRNBuild won't be able
      to create the *.b18 file. Could you please send the *.idf file to
      your distributor so that they can have a look at the cause of the
      errors? If you aren't sure who to contact please email me directly
      and I will point you in the appropriate direction.<br>
    </p>
    <p>thank you in advance,</p>
