 I&amp;#39;m trying to run fatfs example in sdk. I only changed the spi pin numbers. What is wrong with that? 
 
 
 Here is RTT screen. 
 My schematic is; CS-------------P0.08 MOSI----------P0.06 SCK-----------P0.05 MISO----------P0.00

&lt;p&gt;Ok. I recommend (like @awneil suggests)&amp;nbsp;you try this out with a development kit or something similar to narrow down the sources of the problem. If the example works using a development kit, there is likely an issue with your custom board. If it doesn&amp;#39;t work using the DK, there&amp;#39;s a software issue. This will give us a much better starting point to work from.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;

&lt;p&gt;As &lt;a href="https://devzone.nordicsemi.com/members/simonr"&gt;Simonr&lt;/a&gt; said, the first thing to do is to test the application with default pin assignments on a Dev Kit - that way you have a known-good reference to work from&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: NRF52832 FatFs "Disk initialization failed"</title><link>https://devzone.nordicsemi.com/thread/172139?ContentTypeID=1</link><pubDate>Wed, 20 Feb 2019 14:24:53 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:375e7775-1b8d-4b5c-be35-a721b008fe06</guid><dc:creator>bariserbay</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I&amp;#39;m using this breakout board and there is no level converter. Standart sd card working on 3.3V.&lt;/p&gt;

&lt;p&gt;Does the SD card socket boardhave level converters for use with 5V boards? If it does the Fatfs example won&amp;#39;t work unless you power it using a 5V source.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;

&lt;p&gt;I&amp;#39;m using custom board of NRF52832. I&amp;#39;ve checked all default spi&lt;/p&gt;
&lt;p&gt;ports pin configurations but there is no match with default pin&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span&gt;configurations&amp;nbsp;with this board.&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span&gt;I&amp;#39;m waiting your advice.&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;The RTT states that you can&amp;#39;t initialize your disk. Have you tried with the default pin configurations so you are sure that it is the pin config that is wrong here? Only thing I can think of being wrong with the pin configs is that P0.00 is by default used as a pin for the optional crystal (XL1), and that it might be set as that somewhere. Can you try changing just that P0.00 to something else to confirm whether that is the problem or not?&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Simon&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
