<h3>CULflash</h3>
<ul>
  <code>CULflash [fhem-device|none]; &lt;TYPE&gt;</code> <br>
  <br>
    Download the firmware from a nightly SVN chekout and flash the
    hardware.
    Currently the CUL is supported with its versions:
    CUL_V2, CUL_V2_HM, CUL_V3, CUL_V3_ZWAVE, CUL_V4.<br>
    If the fhem-device is none, than the inserted device must already be in the
    flash-mode.<br>
    <b>Note:</b>for flashing the CUL dfu-programmer has to be installed in the
    path, this is already the case with the Fritz!Box 7390 image from
    fhem.de<br>

    Example:
    <ul>
    <code>CULflash CUL CUL_V3<br>
          CULflash none CUL_V3</code>
    </ul>
    Note: the message "dfu-programmer: failed to release interface 0." is
    normal on the FB7390.
</ul>

<h3>CULflash</h3>
<ul>
  <code>CULflash [fhem-device|none]; &lt;TYPE&gt;</code> <br>
  <br>
    L&auml;dt die spezifizierte Firmware von fhem.de und programmiert das
    angeschlossene Ger&auml;t.
    Z.Zt unterst&uuml;tzt wird das CUL und folgende Versionen:
    CUL_V2, CUL_V2_HM, CUL_V3, CUL_V3_ZWAVE, CUL_V4.<br>
    Falls als fhem-device none angegeben wurde, dann muss sich das
    angeschlossene Ger&auml;t bereits in flash-mode befinden.<br>
    <b>Achtung:</b>F&uuml;r CUL flashen muss dfu-programmer installiert und im
    Pfad auffindbar sein, das ist der Fall bei dem Fritz!BOX 7390 Paket von
    fhem.de<br>

    Beispiele:
    <ul>
    <code>CULflash CUL CUL_V3<br>
          CULflash none CUL_V3</code>
    </ul>
    Achtung: die Meldung "dfu-programmer: failed to release interface 0." ist
    auf der FB7390 "normal".
</ul>
