https://devzone.nordicsemi.com/f/nordic-q-a/116382/is-the-mass-storage-example-in-the-nrf-sdk-compatible-only-with-qspiHello, I have a custom board with an nRF52833 and a W25Q512JVEIQ, which communicate over SPI (not QSPI). I successfully accessed the W25Q512JVEIQ (executed my own read and write commands). My next goal is to use the W25Q512JVEIQ external flash memoryen-USTelligent Community 13Fri, 15 Nov 2024 09:26:26 GMThttps://devzone.nordicsemi.com/thread/510634?ContentTypeID=1Fri, 15 Nov 2024 09:26:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c99e0179-2d12-496b-b6fe-8d8192102b26Vidar Berg<p>Hello,</p> <p>You should not have to make any code changes to test this sample on your board. It should be sufficient to add a devictree overlay similar to&nbsp;the&nbsp;nrf52840dk_nrf52840.overlay. The flash device shall be placed in one of your SPI nodes.&nbsp;</p> [quote user=""]My next goal is to use the W25Q512JVEIQ external flash memory as USB mass storage. I reviewed the <code>samples/subsys/usb/mass</code> sample and am trying to adapt it to my project. While researching an issue, I came across an old <a href="https://devzone.nordicsemi.com/support/add/While%20researching%20an%20issue,%20I%20came%20across%20an%20old%20discussion%20where%20it%20was%20mentioned%20that%20the%20nRF5%20SDK%20did%20not%20include%20any%20application%20for%20SPI%20flash">discussion </a>where it was mentioned that the nRF5 SDK did not include any application for SPI flash. Is this still true? In this example, <code>samples/subsys/usb/mass</code> uses QSPI. Can I switch to SPI and use it without issues[/quote] <p>SPI NOR is also supported in the nRF Connect SDK.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
