Armada 3720 alike Board - no PHY devices found by mii info, no ping

Hello list,

I work with a variant of Marvell Armada 3720 board. Recently I upgrade Uboot version from 2017 to 2023.07. As a result PING command failed Original version of 2017 reports on mii info command PCPE>> mii info PHY 0x01: OUI = 0x5A985, Model = 0x2A, Rev = 0x06, 100baseT, HDX Whilst my new 2023 can not find PHY devices

I made minimal changes to configuration and Device tree files. Compilation passed, I loaded Uboot using Uart and it successfully reached PCPE prompt So I tried to test network . Ping correctly reports it uses eth1@neta40000 as output interface (exactly as v2017 does), but ping failed

I did not touch at all PHY and ethernet related definitions, leaving them exactly as it was.

Please advise what to look for.

I do not know how to send full DTS file to list, please instruct me. Meanwhile I do copy-paste. Here snipped of DTSI file --------------------------------------------------------------------------------------------------------- comphy: comphy@18300 { compatible = "marvell,mvebu-comphy", "marvell,comphy-armada-3700"; reg = <0x18300 0x28>, <0x1f300 0x3d000>; mux-bitcount = <4>; max-lanes = <3>; }; -------------------------------------------------------------------------------------------- Here the relevant part of DTS file: &comphy { phy0 { phy-type = <COMPHY_TYPE_SGMII1>; phy-speed = <COMPHY_SPEED_1_25G>; };

phy1 { phy-type = <COMPHY_TYPE_PEX0>; phy-speed = <COMPHY_SPEED_2_5G>; };

phy2 { phy-type = <COMPHY_TYPE_USB3_HOST0>; phy-speed = <COMPHY_SPEED_5G>; }; };

&eth0 { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&rgmii_pins>, <&smi_pins>; phy-mode = "rgmii"; phy_addr = <0x2>; fixed-link { speed = <1000>; full-duplex; }; };

&eth1 { status = "okay"; phy-mode = "sgmii"; phy_addr = <0x1>; fixed-link { speed = <1000>; full-duplex; }; };
