Not able to interface SD card with nrf52840dk_nrf52840

[Kevin_0987654]

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.

Unmodified example code will store the data either in the code flash of the NRF52840 or in the QSPI NOR flash on the DK.

Check the finished dts (build dir / zephyr subdir) for details.

You will need quite a few changes in the overlay in order to enable SD SPI support, this will also set the spi peripherial used and the pins either directly or indirectly.

i saw this post devzone.nordicsemi.com/.../sd-card-error-using-fs_sample-zephyr-example-code and am facing the exact same error here is the output after making changes mentioned in this post.

Is that zephyr.dts? I can't see that your overlay changes have been applied to that. Did you make sure the overlay was included in the build?

[Kevin_0987654]

it is the default dts file that comes with sdk. After few changes in the overlay file

the is a proj_ext.conf in the samples and boards/nrf52840dk_nrf52840.conf, boards/nrf52840dk_nrf52840.overlay, boards/nrf52840dk_nrf52840_qspi.conf, boards/nrf52840dk_nrf52840_qspi.overlay. Im not using any of those in this build. it was getting included automatically but i removed them. Im using the device tree that came with the sdk without making any changes. same for pinctrl. im using v2.6.1 for both toolchain and sdk. I have made no changes to the code at all.

Can you also upload build/zephyr/zephyr.dts to see the dts after building?
