Not able to interface SD card with nrf52840dk_nrf52840

I have created the sample_fs project from subsys/fs/sample_fs. I have not made any changes to the project. I have built it and flashed it onto a nrf52840dk. But I'm getting errors.

*** Booting nRF Connect SDK v3.5.99-ncs1-1 ***

[00:00:00.255,706] <err> main: Storage init ERROR!
[00:00:00.261,413] <err> fs: fs mount error (-5)
Error mounting disk.
[00:00:00.268,859] <err> fs: fs not mounted (mp == 0x20000000)

i tried check the code to see which spi pin it is using but i couldnt find it so i assumed it is spi0 and gave the connections according to the device tree file for spi0. How do I choose the spi? Also i have seen in so
i am using v2.6.1 for both toolchain and nrf connect sdk in VS code.

    i removed this

    partition = <&storage_partition>;
    disk-name = "SD";
    /* cache-size == page erase size */
    cache-size = <4096>;
    }; 

    from the overlay cause it was saying sd card already initialised

  • I was using 3.3V as input instead of 5V. Changing that fixed it. Im sorry i didnt check all of this before hand
