iMX RT1177 ENET driver

[nguyenmthien-GiN]

Hi all 😃
I am trying to bring up the ENET driver for a iMX RT1177 board. Currently we are able to send Ethernet frames but not able to receive them. Can anyone have a look whether our DTS/Kconfig is correct?

Our relevant DTS configs:

&enet_mac {
	status = "okay";
	pinctrl-0 = <&pinmux_enet_mac>;
	pinctrl-names = "default";
	phy-handle = <&enet_phy>;
	phy-connection-type = "rmii";
	zephyr,random-mac-address;
};
 
&enet_mdio {
	/delete-node/ phy@0;
	status = "okay";
	pinctrl-0 = <&pinmux_enet_mdio>;
	pinctrl-names = "default";
	enet_phy: enet_phy@1 {
		compatible = "ethernet-phy";
		reg = <1>;
		status = "okay";
	};
};
 
&enet_ptp_clock {
	pinctrl-0 = <&pinmux_enet_ptp>;
	pinctrl-names = "default";
	status = "okay";
};
 
&enet {
	status = "okay";
};

The Pin controls are:

pinmux_enet_mac: pinmux_enet_mac { /* Eth100 */
    group0 {
        pinmux =
        <&iomuxc_gpio_ad_18_enet_crs>, // crs
        <&iomuxc_gpio_disp_b2_09_enet_rx_er>; // rx_er
        drive-strength = "high";
        bias-pull-down;
        slew-rate = "fast";
    };
    group1 {
        pinmux = <&iomuxc_gpio_disp_b2_06_enet_rdata00>, //rdata00
        <&iomuxc_gpio_disp_b2_07_enet_rdata01>; //rdata01
        drive-strength = "high";
        slew-rate = "fast";
        input-enable;
    };
    group3 {
        pinmux = <&iomuxc_gpio_disp_b2_02_enet_tdata00>,
                    <&iomuxc_gpio_disp_b2_03_enet_tdata01>,
                    <&iomuxc_gpio_disp_b2_04_enet_tx_en>;
        drive-strength = "high";
        slew-rate = "fast";
    };
    group4 {
        pinmux = <&iomuxc_gpio_ad_29_enet_ref_clk>;
        drive-strength = "high";
        slew-rate = "fast";
    };
};
 
pinmux_enet_mdio: pinmux_enet_mdio {
    group0 {
        pinmux = <&iomuxc_gpio_ad_32_enet_mdc>,
                <&iomuxc_gpio_ad_33_enet_mdio>;
        drive-strength = "high";
        slew-rate = "fast";
    };
    group1 {
        pinmux = <&iomuxc_gpio_ad_20_gpio9_io19>; // ETH100_nRST
        drive-strength = "high";
        slew-rate = "fast";
        input-enable;
    };
    group2 {
        pinmux = <&iomuxc_gpio_disp_b2_08_gpio11_io09>; //ENET_nINT
        drive-strength = "high";
        slew-rate = "fast";
        input-enable;
    };
};
 
pinmux_enet_ptp: pinmux_enet_ptp {
};

Our Kconfigs are:

config NET_L2_ETHERNET
	default y # No cache memory support is required for driver
 
config ETH_NXP_ENET_RMII_EXT_CLK
	default y

Hi @nguyenmthien-GiN ,
I also saw on Discord that you are bringing up a custom board. I suggest you compare with a working board like the MIMXRT1170-EVK. Then you can compare the Kconfig and devicetree settings. It would also help to use a debugger and step through the code on both boards to see how they differ.

Let us know what you find. Best regards
