			<description>&#60;p&#62;I'll get the weight and confirm that at the post office.&#60;br /&#62;
The weight of the board and envelope would be around 120 grams. According to royal mail, for the cheapest option to mail this to switzerland it would take 3 pounds. &#60;/p&#62;
&#60;p&#62;So with shipping, 10 pounds per board.&#60;br /&#62;
Both boards, 17 pounds as the postage difference isn't that much.&#60;/p&#62;
&#60;p&#62;Would you only be interested in one?&#60;/p&#62;
&#60;p&#62;My personal mail is &#60;a href=&#34;mailto:bubulindo@gmail.com&#34;&#62;bubulindo@gmail.com&#60;/a&#62;, let me know if you're interested.&#60;/p&#62;
&#60;p&#62;There is one on eBay for 10 pounds... 0 bids after a week. So I decided to try other ways to sell it.&#60;br /&#62;
If you feel more comfortable doing this through eBay I can list it and you purchase through there. &#60;/p&#62;
&#60;p&#62;Let me know by mail. :)

			<description>&#60;p&#62;ala42, thanks for the patch, that is much appreciated. However I already added DFU_LEAVE support some weeks ago, and it was pushed to git early this week. Funny enough another request for it came up on the (brand new) dfu-util mailing list yesterday: &#60;a href=&#34;http://lists.gnumonks.org/pipermail/dfu-util/2012-September/000002.html&#34; rel=&#34;nofollow&#34;&#62;http://lists.gnumonks.org/pipermail/dfu-util/2012-September/000002.html&#60;/a&#62;&#60;/p&#62;
&#60;p&#62;To not introduce a dozen of new command options for DfuSe only, the DfuSe extended commands are instead added as modifiers to the -s argument, for example: &#60;em&#62;dfu-util -s 0x8004000:leave -D file.bin&#60;/em&#62;&#60;/p&#62;
&#60;p&#62;Any testing is very welcome, especially of the &#34;unprotect&#34; and &#34;mass-erase&#34; modifiers, since I do not have hardware to test those.
&#60;/p&#62;</description>

			<description>&#60;p&#62;I also could not find your offer on Ebay, neither on co.uk nor on .com.&#60;/p&#62;
&#60;p&#62;&#38;gt;I could need one of these for testing dfu-util...&#60;br /&#62;
Well, this is a bit of topic, but here is the patch needed for dfu-util to take a STM32F4 out of boot mode, as the --reset option does not work. For the AeroQuad32 project kha and I have added the -L option (leave) which downloads 0 bytes to leave boot mode. This method is listed in the STM application note AN3156, see &#34;5.5 Leave DFU mode&#34;.&#60;br /&#62;

			<description>&#60;p&#62;Hello, &#60;/p&#62;
&#60;p&#62;I bought these when they were launched, but they've been gathering dust in the shelf as I've enrolled in a project management degree and haven't had time to play with these. &#60;/p&#62;
&#60;p&#62;I'm currently in the UK and seeing that these are sold at 9,96 from Farnell I'm willing to sell each for 7 pounds plus shipping. One is still intact as I bought it to have enough for Farnell to send it to me and the other still has the original program installed as the tests I did were all done on the RAM memory. &#60;/p&#62;
&#60;p&#62;I tried eBay, but there's one sitting there without anyone touching it. :(
&#60;/p&#62;</description>
