T1024 ehernet interface doesn't up

[kriptonus]

Hi everyone!

I've tried to compile an image for the t1024 based board. For the building I've used a Buildroot tools and fresh kernel 6.1.44. But ethernet interfaces doesn't up although

 ip a

show me a list of interfaces

give me an error

Is it true that the MDIO is not configured correctly?  I use a device tree from kernel source, Uboot has been kept from previous image (kernel version 3.12.27). I've loaded a new rootfs, dtb and uImage into ram and ran from there.

ethtool show me the next:

Is there some tricks to use ethernet on T1024?

I tried to compile new image from QorIQ SDK 2.0, but it has a very old tools and stopped with a lot of errors.

Please modify the dts file arch/powerpc/boot/dts/fsl/t1024rdb.dts according to your custom board. Please modify "reg" values to your real PHY addresses at mdio@fc000  and mdio@fd000.

fman@400000 {
enet0: ethernet@e0000 {
phy-handle = <&xg_aqr105_phy3>;
phy-connection-type = "xgmii";
sleep = <&rcpm 0x80000000>;
};

enet1: ethernet@e2000 {
sleep = <&rcpm 0x40000000>;
};

enet2: ethernet@e4000 {
phy-handle = <&rgmii_phy2>;
phy-connection-type = "rgmii";
sleep = <&rcpm 0x20000000>;
};

enet3: ethernet@e6000 {
phy-handle = <&rgmii_phy1>;
phy-connection-type = "rgmii";
sleep = <&rcpm 0x10000000>;
};

mdio0: mdio@fc000 {
rgmii_phy1: ethernet-phy@2 {
reg = <0x2>;
};
rgmii_phy2: ethernet-phy@6 {
reg = <0x6>;
};
};

xmdio0: mdio@fd000 {
xg_aqr105_phy3: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c45";
reg = <0x1>;
};
sg_2500_aqr105_phy4: ethernet-phy@2 {
compatible = "ethernet-phy-ieee802.3-c45";
reg = <0x2>;
};
};
};

Thanks a lot. I've solved the issue.
