Hi nvidia team:
I am using ETH3_MDC and ETH3_MDIO connect a 88q4364 T1 phy MDC and MDIO.
reference to 《Adaptation_and_Bringup_for_Jetson_AGX_Orin.pdf》use configuration #1
and enable
mdio configuration in dtsi file.
gbe3-enable-10g;
gbe-uphy-config = <22>;
nvidia,phy-iface-mode = <0>;
phy-handle = <&mgbe3_88q4364_phy>;
mdio {
#address-cells = <1>;
#size-cells = <0>;
compatible = “nvidia,eqos-mdio”;
mgbe3_88q4364_phy: ethernet_phy@3 {
compatible = “ethernet-phy-ieee802.3-c45”;
reg = <0x3>;
interrupt-parent = <&tegra_aon_gpio>;
interrupts = <TEGRA234_AON_GPIO(EE, 5) IRQ_TYPE_LEVEL_LOW>;
};
};
when use oscilloscope measure the ETH1_MDC and ETH1_MDIO,no signal output.
so my question is wheture need some configurations to enable MDC function ?
