Adding another SPI device to app overlay

[sleeper]

Hi,

below is my app overlay, this works and is used for SPI NOR Flash.

What i need to do is add another device to this SPI bus.

Its an accelerometer LIS2DH from STM. How do it change the app overlay to accommodate this new device on the same bus, but with different CS pin.

&spi0 {

    compatible = "nordic,nrf-spim";

    status = "okay";

    pinctrl-0 = <&spi0_sleep>;

    pinctrl-1 = <&spi0_default>;

    cs-gpios = <&gpio1 7 GPIO_ACTIVE_LOW>;

    spi_flash0:spi_flash0@0 {

        compatible = "jedec,spi-nor";

        reg = <0>;

//      irq-gpios = <&gpio0 21 0>;

        spi-max-frequency = <1000000>;

        label = "W25Q64JV";

        jedec-id = [EF 40 17];

        size = <0x4000000>;

    };

};

&pinctrl {

    spi0_sleep: spi0_sleep {

        group1 {

            psels = <NRF_PSEL(SPIM_SCK, 1, 4)>,

           <NRF_PSEL(SPIM_MOSI, 1, 3)>,

           <NRF_PSEL(SPIM_MISO, 1, 6)>;

   

//          low-power-enable;

        };

    };

   

    spi0_default: spi0_default {

        group1 {

            psels = <NRF_PSEL(SPIM_SCK, 1, 4)>,

           <NRF_PSEL(SPIM_MOSI, 1, 3)>,

           <NRF_PSEL(SPIM_MISO, 1, 6)>;

        };  

    };  

};

Also why do i get this warning ?

'label' is marked as deprecated in 'properties:' in C:/ncs/v2.4.0/zephyr/dts/bindings\mtd\jedec,spi-nor.yaml for node /soc/spi@40003000/spi_flash0@0.

The "label" dts property have been deprecated.
Use DT_NODELLABEL instead to get references to DTS nodes.
For example how this is done here: https://github.com/nrfconnect/sdk-nrf/blob/99d94faedc3db9cd640aac12ea3f8849c8ac9651/samples/cellular/lwm2m_client/src/sensors/light_sensor.c#L18

no sure what you mean....???

this is how i get device reference

static const struct device *flash =

    DEVICE_DT_GET(DT_NODELABEL(spi_flash0));

 

this is what the build reports in red

-- Found devicetree overlay: c:/Users/IMS_DEV/Documents/vscode/cdc_acm_composite/app.overlay
'label' is marked as deprecated in 'properties:' in C:/ncs/v2.4.0/zephyr/dts/bindings\mtd\jedec,spi-nor.yaml for node /soc/spi@40003000/spi_flash0@0.

That is becasue your DTS node still has the "label" property:

  spi_flash0:spi_flash0@0 {

        compatible = "jedec,spi-nor";

        reg = <0>;

//      irq-gpios = <&gpio0 21 0>;

        spi-max-frequency = <1000000>;

        label = "W25Q64JV";

        jedec-id = [EF 40 17];

        size = <0x4000000>;

    };

ok that sorted

should i worry about this build warning ?
