You need to use the QSPI peripheral if you want XIP.</p> <p>However, note that the external flash device can be an SPI flash, as long as you use the QSPI peripheral and the external flash supports QSPI peripherals.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/541557?ContentTypeID=1Mon, 07 Jul 2025 06:41:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:12564824-2309-43ec-9a18-e12d15a917c5Turbo J<p>XIP only works with the QSPI peripherial. This is a hardware limitation on NRF chips, look into the datasheet for details.</p><div style="clear:both;"></div>
