Got 2 questions: 
 1.Why does each example project contain blank/mbr/slxxx folders? in these folders they all have a copy of the same project. 
 Does that mean the project in blank does not contain an mbr? if</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 18 Dec 2019 08:06:52 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/55746/why-does-each-example-project-contain-blank-mbr-slxxx-folders" /><item><title>RE: Why does each example project contain blank/mbr/slxxx folders?</title><link>https://devzone.nordicsemi.com/thread/226028?ContentTypeID=1</link><pubDate>Wed, 18 Dec 2019 08:06:52 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:9a040d9f-b139-4baf-a1ac-e9ff8f3099c8</guid><dc:creator>Amanda Hsieh</dc:creator><description>&lt;p&gt;Hi,&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Q1.&amp;nbsp;&amp;nbsp;Why does each example project contain blank/mbr/slxxx folders? in these folders they all have a copy of the same project. Does that mean the project in blank does not contain an mbr? if so how does the code boot on DK?&lt;/p&gt;
&lt;p&gt;&lt;span&gt;A: The MBR - Master Boot Record is used to allow safe update of bootloader on the chip. The MBR is included on the nRF52840 Dongle, as this device contains a bootloader to allow programming applications through the USB port. Please see&amp;nbsp;&lt;/span&gt;&lt;a href="https://devzone.nordicsemi.com/tutorials/b/getting-started/posts/nrf52840-dongle-programming-tutorial"&gt;this tutorial&lt;/a&gt;&lt;span&gt;&amp;nbsp;for more details. Blank directory is used for devices that does not require a MBR/bootloader, for instance the nRF52 DK and nRF52840 DK. BLE examples require a softdevice, and the directories will be named s1xx/s2xx/s3xx, depending on which chip is used and which protocols are supported in the example.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Q2.&amp;nbsp;In segger, there&amp;#39;s solution hierachy and there&amp;#39;s project hierachy. What are the relationships between &amp;quot;solution&amp;#39; and &amp;quot;project&amp;quot;? Why the right-click options show differenct settings when you clicked on &amp;quot;solution&amp;quot; vs &amp;quot;projects&amp;quot;?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;A: Please see&amp;nbsp;&lt;/span&gt;&lt;span&gt;&lt;a href="https://studio.segger.com/index.htm?https://studio.segger.com/ide_project_system_overview.htm"&gt;https://studio.segger.com/index.htm?https://studio.segger.com/ide_project_system_overview.htm&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Q3. the options page contain &amp;#39;common&amp;#39;, &amp;#39;release&amp;#39; and &amp;#39;debug&amp;#39;.&amp;nbsp;what are they and why are they grouped under &amp;quot;public configurations&amp;quot; and &amp;quot;private configurations&amp;quot;?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
