 I am using nRF52832 with sdk15.3 SES 
 I need to use DFU. 
 Buttonless DFU 
 need to program the controller without the wire connection. 
 Can you explain how DFU works and any tutorial or steps to follow to work with SES.

&lt;p&gt;I have created the micro_ecc_lib_nrf52.a&lt;/p&gt;
&lt;p&gt;using minGW&lt;/p&gt;
&lt;p&gt;Can you tell me. the step i followed is ok or not ?&lt;/p&gt;
&lt;p&gt;1. Downloaded and Install &lt;strong&gt;GNU Arm Embedded Toolchain latest version :&lt;/strong&gt; &lt;a href="https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads"&gt;here&lt;/a&gt;&lt;strong&gt; &lt;br /&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;2. changed the GNU_INSTALL_ROOT and GNU_VERSION&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&amp;nbsp; like this&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/6765.10.png" /&gt;&lt;/p&gt;
&lt;p&gt;3. Download and and unzip the micro-ecc folder&lt;/p&gt;
&lt;p&gt;in&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/2148.11.png" /&gt;&lt;/p&gt;
&lt;p&gt;4. Execute msys.bat file from &lt;strong&gt;C:\MinGW\msys\1.0&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;5. moved to my folder ,in my case &lt;/p&gt;
&lt;p&gt;&lt;strong&gt;cd /f/1.nRF52/nRF5_SDK_current/external/micro-ecc/nrf52hf_armgcc/armgcc/&amp;nbsp;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;make&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;the file has created &lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;&lt;img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/2161.12.png" /&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Now I build the secure folder example &lt;/strong&gt;my case&lt;/p&gt;
&lt;p&gt;F:\1.nRF52\nRF5_SDK_current\examples\dfu\secure_bootloader\pca10040_ble\ses&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;

&lt;p&gt;I got Python2.7 in windows 10.&lt;/p&gt;
&lt;p&gt;The thing While installing Python2.7. need to check this&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x240/__key/communityserver-discussions-components-files/4/53045.1.png" /&gt;&lt;/p&gt;
&lt;p&gt;link of the page is &lt;a href="https://www.codeooze.com/coding/python-2715-windows-install/"&gt;here.&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;after this in cmd prompt&lt;/p&gt;
&lt;p&gt;i have run the cmds like&lt;/p&gt;
&lt;p&gt;python&lt;/p&gt;
&lt;p&gt;python -V&lt;/p&gt;
&lt;p&gt;pip&lt;/p&gt;
&lt;p&gt;pip list&lt;/p&gt;
&lt;p&gt;python -m pip install --upgrade pip&lt;/p&gt;
&lt;p&gt;pip install -U setuptools&lt;/p&gt;
&lt;p&gt;pip install nrfutil&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/3630.2.png" /&gt;&lt;/p&gt;

&lt;p&gt;what is this description shows. is it works only upto JAN2020?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/6170.4.png" /&gt;&lt;/p&gt;
&lt;p&gt;Is this right?&lt;/p&gt;
&lt;p&gt;what is the next step to get into DFU&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Buttonless DFU with SES</title><link>https://devzone.nordicsemi.com/thread/202345?ContentTypeID=1</link><pubDate>Mon, 05 Aug 2019 08:43:15 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d7e46fc1-7381-4656-854a-d8cb1cccff56</guid><dc:creator>Ali Rumane</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;I used DFU example on Windows 10 with python 2.7 some time before and it worked well.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
[quote userid="74103" url="~/f/nordic-q-a/50096/buttonless-dfu-with-ses/202271"]&lt;p&gt;Is that DFU secure bootloader need Ubuntu / Linux OS support?&lt;br /&gt;&lt;/p&gt;&lt;p&gt;&lt;/p&gt;[/quote]
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I don&amp;#39;t think it should be an issue and should work well with Windows 10.&lt;/p&gt;
&lt;p&gt;If you don&amp;#39;t use python for any other purpose, uninstall python 3 and keep only python 2.7 as it is mentioned in prerequisites to use python 2.7.&lt;/p&gt;
&lt;p&gt;&lt;pre class="ui-code" data-mode="text"&gt;Prerequisites
To install nrfutil from source the following prerequisites must be satisfied:

1.  Python 2.7 (2.7.10 or newer, not Python 3)
2.  pip
3.  setuptools (upgrade to latest version): pip install -U setuptools&lt;/pre&gt;&lt;/p&gt;
&lt;p&gt;After installing python 2.7 and nrfutil, try running the example and if it doesn&amp;#39;t work please add the logs generated so that we may know what the issue is.&lt;/p&gt;
&lt;p&gt;Regards&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Buttonless DFU with SES</title><link>https://devzone.nordicsemi.com/thread/202271?ContentTypeID=1</link><pubDate>Sun, 04 Aug 2019 11:00:23 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b4079ecf-6b1b-460d-a18b-469b87d5315e</guid><dc:creator>Sunil vignesh</dc:creator><description>&lt;p&gt;My Query is have i Windows 10. I have download the nrfutil.exe from &lt;a href="https://github.com/NordicSemiconductor/pc-nrfutil/releases"&gt;here&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;While i run the exe file, within a few seconds the exe file closed.&lt;/p&gt;
&lt;p&gt;During this i have not installed any version of Python.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;After that I have installed Python 2.7.12&lt;/p&gt;
&lt;p&gt;but running the CMD and enter python it when to store to install Python 3.7&lt;/p&gt;
&lt;p&gt;I am not understanding.&lt;/p&gt;
&lt;p&gt;Is that DFU secure bootloader need&lt;/p&gt;
&lt;p&gt;Ubuntu / Linux OS support?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Buttonless DFU with SES</title><link>https://devzone.nordicsemi.com/thread/202270?ContentTypeID=1</link><pubDate>Sun, 04 Aug 2019 09:09:33 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:c5b0dc3b-cddb-46d3-a405-9808dc78de7c</guid><dc:creator>Sunil vignesh</dc:creator><description>&lt;p&gt;If I use nrfutil.exe &lt;/p&gt;
