https://devzone.nordicsemi.com/f/nordic-q-a/28947/what-does-qspi-activate-task-doWhat does the QSPI controller inside the nRF52840 do when the ACTIVATE task is started? Does the ACTIVATE task result in communications with the external QSPI part such as some kind of handshaking such as QPSI part identification?

I have reported it internally, and we will add timeout or some other recovery solution in future releases. If you do not want to change the driver yourself to add a timeout, you can setup the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.ps/wdt.html?cp=2_0_0_38#concept_ywz_4xw_sr">watchdog timer peripheral</a> to recover from such situatuions. This will trigger MCU reset, but at least you get out of the blocking loop.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
