https://devzone.nordicsemi.com/f/nordic-q-a/61482/watchdogHi, I&#39;m using NRF_WDT and it works very good. I would like to investigate my project failures and I want to save some data when watchdog is expired. How can I catch the watchdog before it reset my application, so I will be able to save dataen-USTelligent Community 13Mon, 18 May 2020 12:14:57 GMThttps://devzone.nordicsemi.com/thread/250433?ContentTypeID=1Mon, 18 May 2020 12:14:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0e3790a8-0b9b-4279-a003-94a3b13ef0cbVidar Berg<p>Hi,</p> <p>You can enable interrupt for the WDT TIMEOUT event to get notified when the WD has timed out, see <span><a title="Watchdog reset" href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/wdt.html?cp=4_0_0_5_35_2#concept_b4n_xzw_sr">Watchdog reset. </a></span><span>The limitation is that you only get ~2 32KHz clock cycles inside the WDT interrupt handler before the reset is effectuated, so it&#39;s not giving you enough time to store information to flash. Instead you may try to store it to a &quot;non initialized&quot; section of RAM as my colleague Sigurd suggested in this thread: <a href="https://devzone.nordicsemi.com/f/nordic-q-a/30075/saving-the-location-of-watchdog-timeout">https://devzone.nordicsemi.com/f/nordic-q-a/30075/saving-the-location-of-watchdog-timeout</a> </span></p><div style="clear:both;"></div>
