https://devzone.nordicsemi.com/f/nordic-q-a/35660/nrf52840-with-serial-nandHi there, I have found a similar thread that dates back from a year ago ( https://devzone.nordicsemi.com/f/nordic-q-a/29073/altering-qspi-address-mode ) but I would like to have an update. It seems that back then QSPI IP wasnt compatible in termsen-USTelligent Community 13Mon, 25 Jun 2018 13:37:09 GMThttps://devzone.nordicsemi.com/thread/137455?ContentTypeID=1Mon, 25 Jun 2018 13:37:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:60c327c7-9b40-4e86-89e1-9634c66dd970bjorn-spockeli<p>Hi Michael,</p> <p>As far as I know the answer in the thread you&#39;re referring to is still valid, i.e. the QSPI IP does not allow us to modify the addressing scheme to work with the&nbsp;&nbsp;MICRON Serial NAND protocol. Hence the possible workarounds is to use the&nbsp;SPIM3 peripheral which supports 32MHz or use the custom instruction feature of the QSPI, see&nbsp;<a title="Sending custom instructions" href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.ps/qspi.html?cp=2_0_0_5_18_5#custom_instructions">Sending custom instructions</a>.</p><div style="clear:both;"></div>
