My experience is that a frame in a single buffer description is always sent twice, which never happens when more than one buffer is available. You can also prepare the frame to be transmitted to be chained in 2 buffer descriptions (eg. IP part in first and UDP etc. part in second). which shoud stop it happening.<BR /><BR />If you find another solution, please also let us know!!<BR /><BR />Regards<BR /><BR />Mark Butcher<BR /><BR /><A href="http://www.uTasker.com" rel="nofollow" target="_blank"><IMG src="http://www.uTasker.com/uTaskerLogoSS.jpg" /></A><P>Message Edited by mjbcswitzerland on <SPAN class="date_text">2007-02-06</SPAN><SPAN class="time_text">07:28 PM</SPAN></P></BODY></HTML> Wed, 07 Feb 2007 03:26:18 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Ethernet-problem-M52233demo-send-double-messages/m-p/144612#M2968 mjbcswitzerland 2007-02-07T03:26:18Z
