SDCard with SPI doesn't works for nRF5340

[warcomeb-am]

Hi, 

I am trying to use the SDCARD with nRF5340 and I have some problems. The first is this. The second one is the following:

I created a new workspace and a new project based on fat_fs example without any modifications. The configuration of overlay is the following

&spi2 {
    status = "okay";
    compatible = "nordic,nrf-spim";
    //sck-pin = < 44 >;
    //miso-pin = < 43 >;
    //mosi-pin = < 42 >;

    group1 {
        psels = < NRF_PSEL(SPIM_MOSI, 1, 10) >,
               < NRF_PSEL(SPIM_MISO, 1, 11) >,
               < NRF_PSEL(SPIM_SCK, 1, 12)>;
    };

    cs-gpios = < &gpio1 9 GPIO_ACTIVE_LOW >;
    sdhc0: sdhc@0 {
        compatible = "zephyr,mmc-spi-slot";
        reg = < 0x0 >;
        status = "okay";
        label = "SDHC0";
        spi-max-frequency = < 4000000 >;
    };
};

The project compile, but in the trace is present the following line:

CMake Warning at C:/Users/x/ncs/v2.1.2/zephyr/CMakeLists.txt:831 (message):
  No SOURCES given to Zephyr library: drivers__disk

And, when I programming the chip, the three SPI pins is low and no signal is present (I checked with logic analyzer)!

I don't know what is the issue, but I suppose is the line mentioned before.

I am using win, with 2.1.0 SDK.

Hi Macro,

Thank you for contacting DevZone at NordicSemi.

I have been assigned this ticket, and I will look into this case.

Can you please send in your minimal project.

It will help me reproduce the error and debug more into it.

Thanks,

Naeem

Hi Naeem Maroof ,

Thanks for your reply.

In attach you can find the zip of the minimal project.

Hi Macro,

Thank you for sending zip file.

How are you connecting your SDCard?

Are you sure you card is connected to the correct pins?

Also, goes the chip-select signal need to be active-low?

You can try with active-high to do an experiment (after confirming connections to the correct pins).

Hi Naeem,

We are connecting the SDCard by wire. It is not a beautiful solution, but it just for prototype (the final PCB arrive very soon!).

Yes, I am sure the pin is connected to SDCARD, I checked with multimeter.

Yes, the CS need to be active-low, anyway I have tried with active-high but nothing change.

The three pin of SPI is always low, and the CS is always high. I check the signals with logic analyzer (SALEAE).

Are you sure that the previous line that appear during compilation is not important?

Hi Macro,

Thank you for being patient.

I am sorry that I overlooked that warning. Yes, it could a related thing along with correct connections and configurations of the SDCard.

I tried to find more about resolving that drivers__disk warning, but it looks like some configuration missing / conflict issue.

Following this thread (Fat_FS_Sample_Error) and found that the same code is working in 1.9.1 but giving different issues in 2.1.0.
