https://devzone.nordicsemi.com/f/nordic-q-a/35197/pstorage_init-hangs-no-sdHi I am trying (for the first time) to deal with flash. Hence, I started by a simple app, without BLE/SD (blinker) The problem is that, the first API call pstorage_init hangs dont know why... #include &lt;stdbool.h&gt; #include &lt;stdint.h&gt; #includeen-USTelligent Community 13Tue, 12 Jun 2018 07:05:50 GMThttps://devzone.nordicsemi.com/thread/135669?ContentTypeID=1Tue, 12 Jun 2018 07:05:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5a15de14-fd85-4887-a683-30fa0ea45d71run_ar<p>I think you must have misunderstood <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/compatibility_matrix/ic_rev_sdk_sd_comp_matrix.html?cp=2_1_3_2">the matrix</a>. nRF52832 rev 2 is compatible with Softdevice v6, and SDK v15.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/135256?ContentTypeID=1Thu, 07 Jun 2018 21:00:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7bafa123-e783-4b95-8892-7e3191d5d57bAlex Co<p>uC rev 2... according to compliance matrix... only the sdk 6 samples work well. </p> <p>Ok, I missed Specifics and limitations of the sdk implementation</p> <p>Understood!

Anyway, pstorage needs the SD api&#39;s to function so you cannot use it without the sd. Documentation for <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk51.v9.0.0/lib_pstorage.html?cp=4_0_11_3_13_4#pstorage_implement_specifics">sdk9 here</a>. (Unfortunately I do not have aonline documentation for sdk 6, but it should be roughly the same)</p><div style="clear:both;"></div>
