Y0g1

hi 

i was trying to interface sd card with nrf9160 in segger emstudio. i was following the ticket Reading SD card on nRF9160dk - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com) but no output message is printing on terminal all the settings are same as discussed in ticket. please guide me for solving the issue.

    Ok, and what error code do you get? Did you try using the samples found under ncs/zephyr/samples/subsys/fs/fat_fs?

    zephyr\lib\libc\minimal\include\errno.h gives the following description of error -5

    #define EIO 5		/* I/O error */

    Here is what I get from the output, when running on nRF9160DK without a SD card reader:

    How have you connected your SD card to the board?

    What pins are you using? Please make sure to use pins that are not controlled by the board controller.

    If you are using pins controlled by it, have you configured the board controller?

    Have you verified correct output to pins in your overlay? Please measure the output on the pins connected to your SD card to verify functionality using a oscilloscope. 

    Kind regards,
    Øyvind

    i am not using the kit we designed a custom pcb which includes the sd card so not role of the kit controller settings i think.
