Peripheral Ethernet[edit | edit source]
The ethernet interface is made available through the i.MX93 eqos interface which should be initialized on the device tree.
Device tree configuration[edit | edit source]
Here below is an example of device tree configuration used on standard DAVE's kit for the AURA SOM:
From imx93-aura.dtsi :
&eqos {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_eqos>;
phy-mode = "rgmii-id";
phy-handle = <ðphy1>;
status = "okay";
mdio {
compatible = "snps,dwmac-mdio";
#address-cells = <1>;
#size-cells = <0>;
clock-frequency = <5000000>;
ethphy1: ethernet-phy@7 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <7>;
eee-broken-1000t;
};
};
};
...

Accessing the peripheral[edit | edit source]
AURA SOM provides the network interface mapped as eth0.
