  • Hi

    What kind of hardware are you using? 

    Have you ensured that the SD card is correctly connected to the nRF52 device?

  • Hi

    Have you tried to scope the SPI lines to see if there is any communication happening between the nRF52 and the SD card?

  • Hi 

    Which Zephyr version are you using?

    Is it a tagged release, or the master branch?

    I have a SD card laying around and will try to reproduce your issue tomorrow. 

    Best regards
