https://devzone.nordicsemi.com/f/nordic-q-a/121109/problem-interfacing-at25xe321d-with-qpsiHi there, I am trying to interface at25xe321d with QSPI but it always end up returning zeros. Please find attached code and dts file for reference.

From the code snippets you posted it appears you have implemented your own driver using the nrfx HAL. Please try the spi_flash (project path: /zephyr/samples/drivers/spi_flash/) and see if you get the same result with this sample which uses the QSPI NOR driver from Zephyr. If this also fails,&nbsp;please try&nbsp;lowering the clock frequency to 1M and change from quad to single line read/write (fastread/pp) to help rule out other issues.</p> <p>Thanks,</p> <p>Vidar</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/533947?ContentTypeID=1Mon, 05 May 2025 14:22:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1e3bedc4-60c0-4d9c-995d-e86f938926d3Moh<p>Hi, Any update regarding my ticket?
