https://devzone.nordicsemi.com/f/nordic-q-a/87862/nrf-calendar-on-nrf-connect-sdk-crash-when-calling-irq-handlerHello, I am trying to implement the nrf5-calendar-example for the nrf connect SDK for the board nrf9160dk_nrf52840. I am able to compile the code for this board with the nrf connect SDK by changing some functions (strftime, mktime and localtime) as wellen-USTelligent Community 13Fri, 27 May 2022 10:13:00 GMThttps://devzone.nordicsemi.com/thread/369744?ContentTypeID=1Fri, 27 May 2022 10:13:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cd5b2502-f1c2-4ab2-b834-39ad9ef6f94dGaspard<p>Hello,<br /><br />Sorry for the delay. I was not really sure about the cause of the crash as i was only seeing the device rebooting every time the IRQ was called without any error displayed. <br />But, I now use the <a href="https://docs.zephyrproject.org/apidoc/latest/group__counter__interface.html">counter API</a> instead to measure time for the calendar and it works well for me. </p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/367933?ContentTypeID=1Sun, 15 May 2022 12:42:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0b0ebdb4-982c-4025-b6c7-c228c4a7df0fSusheel Nuguru<p>Not sure what kind of crash you get.
