The question is: why is this value?</p> <p>According to S130_SDS (v2.0) table 27,&nbsp; the required memory resource is 104 KB and APP_CODE_BASE = 0x1B000. Therefore, it seems that nRFGo Studio takes APP_CODE_BASE for CLENR0.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/142792?ContentTypeID=1Fri, 03 Aug 2018 11:34:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c2d11da6-0a14-4fe7-8c1b-b70991ab644eH&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>Are you sure you&#39;re not reading the content with different byte endianess?</p> <p>If you reverse the byte order:</p> <p>00 b0 01 00 -&gt; 00 01 b0 00</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Håkon</p><div style="clear:both;"></div>
