If your board shipped with an older version of the OB J-Link firmware, the legacy driver will be required to interface with the board. The firmware will be updated automatically afterward to no longer require the legacy driver.</span></p> <p><span>Regards,<br />Amanda H.</span></p><div style="clear:both;"></div>
