Hi,

The problem is solved. I am able to mount the SD card.

I followed this thread https://devzone.nordicsemi.com/f/nordic-q-a/59430/nrf9160-sd-card-access-via-spi/242347#242347 and added CONFIG_SPI_NRFX_RAM_BUFFER_SIZE=8 in prj.conf file. It is working.

Thanks a lot for your help.

Thanks for the project. I checked it, but still that error shows. Can you tell me which SD card is being used and how it is connected. Now the drivers and program is same still that error is there, it means there might be the problem in SD card board. But this same breakout board is used to interface with nRF52840DK and with that it is working fine.

Hi,

I am using adafruit micro-sd breakout board and kingston micro sd card 8GB which is formatted to FAT32 Filesystem.

Connections are as follow:

SCK (Pin 11) -> CLK

MOSI (Pin 12) -> DI

MISO (Pin 13) -> DO

CS (Pin 10) -> CS

Picture of the setup:

I tested zephyr/tests/subsys/fs/multi-fs to check fatfs and it is working properly. It can create the directory and files on the RAM of nRF9160.

The error is coming from disk_access_init() function.

I checked the drivers and it looks correct. I checked the SD card commands, they are also correct. In previous version there was issue but it is fixed now for this version. Still that error comes.

So the problem is either in disk_access_spi_sdhc file or in the sd card. Because SPI is getting initialized.

Hello,

Attached is a working project using SPI3. The output is shown in the image.

&spi3 {
        compatible = "nordic,nrf-spim";
        status = "okay";
        sck-pin = <10>;
        mosi-pin = <11>;
        miso-pin = <12>;

        cs-gpios = <&gpio0 13 0>;

        sdhc0: sdhc@0 {
                compatible = "zephyr,mmc-spi-slot";
                reg = <0>;
                status = "okay";
                label = "SDHC0";
                spi-max-frequency = <24000000>;
        };
};

Let me know how it works for you!

Hello,

[quote user="Jagruti_N2A"]Instead of disk_access_spi_sdhc, can I use app_sdcard on nRF9160? I guess app_sdcard uses nrf legacy drivers. My collegue has used app_sdcard on nRF52840DK to interface with SD card. So is it possible to use with nRF9160DK instead of Zephyr drivers?[/quote]

The app_sdcard is a library from the nRF5 SDK. You can use this but will need to port to nRF9160.

Can you please provide more information about your setup? Can you take a picture to show how you have connected?

Have you ensured that the pins are correctly configured in the board controller? P0.13 on the board controller must be set to enable these pins.

To minimize editing the board controller, can you please route SPI3 to P0.10 - P0.13 instead? These are found on P19 and should be directly available.

Kind regards,
Øyvind

Hello,

I downloaded the merged.hex file which you provided and I think it is working. LED on SD card is continuously blinking which means it is continuously receiving the clock signal.

When I download my merged.hex file, LED stops working after 10-15sec indicating that SD card is not mounted and it stops receiving clock signal.

I compared both merged.hex files and they are different.

I am using the same ncs tag, overlay file and prj.conf file as yours. Still it is different.

I think in my program, spi is never initialized. Can you please guide me for this problem?

Yes I have connected the SD card.

OK I will not change the zephyr branch. I will try to ask in the Zephyr community. Thanks for the help.

[quote user="Jagruti_N2A"]Can you please provide your merged.hex file? So that I will check it on my DK. Thank you in advance.[/quote]

Yes, here is my merged.hex. devzone.nordicsemi.com/.../merged.hex

[quote user="oys"]Have you connected the SD card?[/quote]

I did not get a clear answer to this. How have you connected your SD card? As mentioned, I do not have access to an SD card at the moment.

[quote user="Jagruti_N2A"]They are also getting this same error. I tried with zephyr branch v2.2, but using it with ncs tag v1.2.0 shows error. So I am using v2.1.99-ncs1 zephyr. I don't know what else to try.[/quote]

There is no need to change the Zephyr branch from what is recommended in NCS. However, please note that this example is not made by Nordic, it is made by the Zephyr community and for another board than nRF9160. It may be worth a try to ask for help in the Zephyr community, e.g. this thread.

Thanks!

The error is still there. When I remove the overlay file, I get the same output like you. I am not understanding what is the problem. I referred to other questions likehttps://devzone.nordicsemi.com/f/nordic-q-a/57194/nrf9160-and-sd-card-example and https://devzone.nordicsemi.com/f/nordic-q-a/51379/fat-file-error. They are also getting this same error. I tried with zephyr branch v2.2, but using it with ncs tag v1.2.0 shows error. So I am using v2.1.99-ncs1 zephyr. I don't know what else to try.

For this example how the spi drivers are initialized I am not getting. Normally to use any drivers we use device get binding() function. For this example where it is done?

Is there any other way to interface SD card with nRF9160dk?

RE: Reading SD card on nRF9160dk

Øyvind — Fri, 20 Mar 2020 11:54:45 GMT

Ok, so I've tested here and I was able to remove the first error: spi_nrfx_spim: CS control inhibited (no GPIO device) I added CONFIG_GPIO = y to the top of prj.conf.

Have you connected the SD card? I am currently in my home office and do not have access to any SD cards or measuring devices.

What does your prj.conf look like?

RE: Reading SD card on nRF9160dk

Jagruti — Thu, 19 Mar 2020 16:38:05 GMT

One more thing is, this example is written for nrf52840_blip board. But I want to use fatfs library for nrf9160dk.

In the zephyr documentation it is written;

This sample can be built for an nrf52840_blip board. It requires both the nrf52840_blip.overlay and the dts_fixup.h for nrf52840_blip to work:

So that's why I added nrf9160_pca10090ns.overlay for the project and removed nrf52840_blip.overlay file

But I think the C Code should remain same as it is using FATFS library.

Is it ok to use this code and FATFS library for nrf9160dk? Are there any changes required to use it on nrf9160dk?

Hi,

SES is working properly with ncs tag v1.2.0

I tried few samples and it is working fine.

But the error is same as v1.0.0

*** Booting Zephyr OS build v2.1.99-ncs1  ***
[00:00:00.004,211] [0m<inf> spi_nrfx_spim: CS control inhibited (no GPIO device)[0m

Error mounting disk.
[00:00:10.008,789] [1;31m<err> fs: fs mount error (-5)

Why it always shows CS control inhibited (no GPIO device)? It means CS pin is not getting configured. I have defined the pin in overlay file.

Also, is there a reason for why you did not try git stash when you did git checkout v1.2.0? Be aware that a lot of bug fixes are included in the latest version

RE: Reading SD card on nRF9160dk

Did you remember to run west update after git checkout v1.1.0?
