SPI on QSPI pins (NRF52840 DKhttps://devzone.nordicsemi.com/f/nordic-q-a/114223/spi-on-qspi-pins-nrf52840-dkHi there, I am using the NRF52840DK development board as a learing experience. I have used the EXCERCISE8 on the Nordic learning program and created a SPI driver for a simple device. This works when the pins are NOT linked to QSPI pins.

If SW6 nRF_ONLY position is required the flash links to those pins SB10-SB15&nbsp;must all be&nbsp;broken (disconnected).</p><div style="clear:both;"></div>RE: SPI on QSPI pins (NRF52840 DKhttps://devzone.nordicsemi.com/thread/499777?ContentTypeID=1Mon, 26 Aug 2024 13:25:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5c3df8f6-5cbe-434c-8026-6e45bea87853RichardPa<p>I have checked the configs .. SPI is configured on the correct pins - QSPI is disabled - but yet, I get no data on MOSI and CS.&nbsp;&nbsp; Clock works as its not on a QSPI pin.</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1724678563267v1.png" alt=" " /></p> <p></p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1724678628597v2.png" alt=" " /></p><div style="clear:both;"></div>
