Intergrate W5500 with an nRF54L15DK

[Timothy01]

I am working on a school project and need to set up SPI communication between a wiznet,W5500 and the nRF54L15DK. I can build and run my program but I am getting no responce when I ping the device. When looking over my prj.conf I have a warning associated to CONFIG_ETH_W5500=y that says 

CONFIG_ETH_W5500 was assigned the value y, but got the value n. Missing dependencies:

DT_HAS_WIZNET_W5500_ENABLED.

Here is the prj.conf

# Networking config
CONFIG_NETWORKING=y

# w5500 driver config
CONFIG_SPI=y
CONFIG_NET_L2_ETHERNET=y
CONFIG_ETH_W5500=y


# Network address config
CONFIG_NET_CONFIG_SETTINGS=y
CONFIG_NET_CONFIG_NEED_IPV4=y
CONFIG_NET_CONFIG_MY_IPV4_ADDR="192.168.101.52"
CONFIG_NET_CONFIG_PEER_IPV4_ADDR="192.168.1.1"

# choose RTT console or UART console
CONFIG_SERIAL=y
CONFIG_UART_CONSOLE=y
CONFIG_CONSOLE=y
CONFIG_USE_SEGGER_RTT=n
CONFIG_RTT_CONSOLE=n

# General config
CONFIG_LOG=y
CONFIG_LOG_DEFAULT_LEVEL=3
CONFIG_NET_LOG=y

Here is the overlay

&pinctrl {
    spi22_default: spi22_default {
        group1 {
            psels = <NRF_PSEL(SPIM_SCK, 2, 7)>,
                    <NRF_PSEL(SPIM_MOSI, 2, 6)>,
                    <NRF_PSEL(SPIM_MISO, 2, 8)>; 
        };
    };

    spi22_sleep {
        group1{
            psels = <NRF_PSEL(SPIM_SCK, 2, 7)>,
                    <NRF_PSEL(SPIM_MOSI, 2, 6)>,
                    <NRF_PSEL(SPIM_MISO, 2, 8)>; 
            low-power-enable;
        };
    };
};

// Enable wiznet W5500
&spi22 {
    compatible = "nordic,nrf-spim";
    status = "okay";
    pinctrl-0 = <&spi22_default>;
    pinctrl-1 = <&spi22_sleep>;
    pinctrl-names = "default", "sleep";
    cs-gpios = <&gpio2 9 GPIO_ACTIVE_LOW>;

    w5500: w5500@0 {
        compatible = "wiznet,w5500";
        label = "w5500";
        reg = <0>;
        spi-max-frequency = <8000000>;
        reset-gpios = <&gpio2 10 GPIO_ACTIVE_LOW>;
        int-gpios = <&gpio2 3 GPIO_ACTIVE_LOW>;
        status = "okay";
    };
};

// Enable UART for console output
&uart20 {
    status = "okay";
};

// Disable unused LEDS
&led0 {
    status = "disabled";
};

&led2 {
    status = "disabled";

Currently just trying to make the warning go away but also wondering why I can't ping the device.

Hi

It seems like you're using P2.03 for an int GPIO in your WIZNET overlay. This one is connected to SPI and not the P2 header on the nRF54L15 DK. You need to use the board configurator app to disable the external flash.

Additionally, I don't know the specifics of this module, but what voltage does the WIZNET run on?

For the warning, the configuration option DT_HAS_WIZNET_W5500_ENABLED is not user-configurable. This means that you cannot set this configuration yourself. It can only be configured internally, for example, by other configuration options or devicetree. In this case, it is set by W5500 being enabled in devicetree. Remove this from prj.conf, and the error will disappear.

Best regards,

Simon

Thank you for the reply.  As far as the W5500 I am using, it's uses 3.3V working power. I set up the board in the nRF connect for desktop to supply 3.3 V to Vdd. I also used the SPI set up called out in the nRF connect SDK intermediate lesson 5 exersice 1 from DevAcademy. My SPI interface is now up and I can ping the device.

Thanks,

Tim
