mbr vs. blank?https://devzone.nordicsemi.com/f/nordic-q-a/45732/mbr-vs-blankIn the 15.3 SDK I see different IDE projects setting under peripheral &quot;mbr&quot; directory and the &quot;blank&quot; directory.

(since MBR is used to update the bootloader/softdevice).<br />Thank you.</p> <div class="LTRStyle" style="direction:ltr;display:none;text-align:left;" id="WidgetFloaterPanels"> <div style="display:none;" id="WidgetFloater"> <div id="WidgetLogoPanel"><span id="WidgetTranslateWithSpan"><span>TRANSLATE with </span></span> <span id="WidgetCloseButton" title="Exit Translation">x</span></div> <div id="LanguageMenuPanel"> <div class="DDStyle_outer"><span class="DDStyle" id="__LanguageMenu_header">English</span> <div style="left:0;position:relative;text-align:left;"> <div style="position:absolute;"> <div class="DDStyle" style="display:none;" id="__LanguageMenu_popup"> <table id="LanguageMenu" border="0"> <tbody> <tr> <td><a href="#ar">Arabic</a></td> <td><a href="#he">Hebrew</a></td> <td><a href="#pl">Polish</a></td> </tr> <tr> <td><a href="#bg">Bulgarian</a></td> <td><a href="#hi">Hindi</a></td> <td><a href="#pt">Portuguese</a></td> </tr> <tr> <td><a href="#ca">Catalan</a></td> <td><a href="#mww">Hmong Daw</a></td> <td><a href="#ro">Romanian</a></td> </tr> <tr> <td><a href="#zh-CHS">Chinese Simplified</a></td> <td><a href="#hu">Hungarian</a></td> <td><a href="#ru">Russian</a></td> </tr> <tr> <td><a href="#zh-CHT">Chinese Traditional</a></td> <td><a href="#id">Indonesian</a></td> <td><a href="#sk">Slovak</a></td> </tr> <tr> <td><a href="#cs">Czech</a></td> <td><a href="#it">Italian</a></td> <td><a href="#sl">Slovenian</a></td> </tr> <tr> <td><a href="#da">Danish</a></td> <td><a href="#ja">Japanese</a></td> <td><a href="#es">Spanish</a></td> </tr> <tr> <td><a href="#nl">Dutch</a></td> <td><a href="#tlh">Klingon</a></td> <td><a href="#sv">Swedish</a></td> </tr> <tr> <td><a href="#en">English</a></td> <td><a href="#ko">Korean</a></td> <td><a href="#th">Thai</a></td> </tr> <tr> <td><a href="#et">Estonian</a></td> <td><a href="#lv">Latvian</a></td> <td><a href="#tr">Turkish</a></td> </tr> <tr> <td><a href="#fi">Finnish</a></td> <td><a href="#lt">Lithuanian</a></td> <td><a href="#uk">Ukrainian</a></td> </tr> <tr> <td><a href="#fr">French</a></td> <td><a href="#ms">Malay</a></td> <td><a href="#ur">Urdu</a></td> </tr> <tr> <td><a href="#de">German</a></td> <td><a href="#mt">Maltese</a></td> <td><a href="#vi">Vietnamese</a></td> </tr> <tr> <td><a href="#el">Greek</a></td> <td><a href="#no">Norwegian</a></td> <td><a href="#cy">Welsh</a></td> </tr> <tr> <td><a href="#ht">Haitian Creole</a></td> <td><a href="#fa">Persian</a></td> <td></td> </tr> </tbody> </table> </div> </div> </div> </div> </div> <div id="CTFLinksPanel"><span id="ExternalLinksPanel"><a id="HelpLink" title="Help" href="https://go.microsoft.com/?linkid=9722454" rel="noopener noreferrer" target="_blank"> </a> <a id="EmbedLink" title="Get this widget for your own site"></a> <a id="ShareLink" title="Share translated page with friends"></a> </span></div> <div id="FloaterProgressBar"><span id="ProgressFill"></span></div> </div> <div style="display:none;" id="WidgetFloaterCollapsed"><span>TRANSLATE with </span></div> <div style="display:none;" id="FloaterSharePanel"> <div id="ShareTextDiv"><span id="ShareTextSpan"> COPY THE URL BELOW </span></div> <div id="ShareTextboxDiv"><!--a id="TwitterLink" title="Share on Twitter"> <img id="TwitterImg" /></a> <a--> <a id="EmailLink" title="Email this translation"></a> </div> <div id="ShareFooter"><span id="ShareHelpSpan"><a id="ShareHelpLink"></a> </span> <span id="ShareBackSpan"><a id="ShareBack" title="Back To Translation"></a> Back</span></div> </div> <div style="display:none;" id="FloaterEmbed"> <div id="EmbedTextDiv"><span id="EmbedTextSpan">EMBED THE SNIPPET BELOW IN YOUR SITE</span> <a id="EmbedHelpLink" title="Copy this code and place it into your HTML."></a> </div> <div id="EmbedTextboxDiv"></div> <div id="EmbedNoticeDiv"><span id="EmbedNoticeSpan">Enable collaborative features and customize widget: <a href="http://www.bing.com/widget/translator" rel="noopener noreferrer" target="_blank">Bing Webmaster Portal</a></span></div> <div id="EmbedFooterDiv"><span id="EmbedBackSpan">Back</span></div> </div> </div><div style="clear:both;"></div>RE: mbr vs. blank?https://devzone.nordicsemi.com/thread/180207?ContentTypeID=1Thu, 04 Apr 2019 08:35:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b80d13bc-2967-46e1-936a-b5cf64ce4163J&#248;rgen Holmefjord<p>Hi,</p> <p>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 <a href="https://devzone.nordicsemi.com/tutorials/b/getting-started/posts/nrf52840-dongle-programming-tutorial">this tutorial</a> 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.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
