Hello Liming,<br />Yes this check is only done for '.h' files. Cf the bit of code from the same file:<br /><br />if os.path.splitext(F)[1] in ('.h'):<br />&nbsp; self.NamingConventionCheckIfndefStatement(FileTable)<br /><br />I think this is normal, the format of the initial 'ifndef' needs to be formatted as 'Name_', but not necessarilly all the other 'ifndef' in the file.<br />I added the arm copyright two times, I will submit a v2 if the patch goes forward.<br /><br />Regards,<br />Pierre
