LS1028: could not attach to PHY

Hi, 

I have a problem with connecting to Ethernet(SGMII and RGMII) in our custom board based on LS1028.

Please find the output from connecting to SGMII and RGMII below:

root@root:~# ip link set up eth0
[ 344.709641] net eth0: could not attach to PHY
ip: SIOCSIFFLAGS: No such device

root@root:~# ip link set up eth1
[ 397.709310] net eth1: could not attach to PHY

ip: SIOCSIFFLAGS: No such device

The eth dts configuration:

&enetc_port0 {
phy-handle = <&sgmii_phy0>;
phy-connection-type = "sgmii";

mdio {
#address-cells = <1>;
#size-cells = <0>;
sgmii_phy0: ethernet-phy@2 {
reg = <0x2>;
max-speed = <1000>;
// interrupt-parent = <&gpio1>;
// interrupts = <25 IRQ_TYPE_EDGE_FALLING>;
};
};
};

&enetc_port1 {
phy-handle = <&rgmii_phy0>;
phy-connection-type = "rgmii";

mdio {
#address-cells = <1>;
#size-cells = <0>;
rgmii_phy0: ethernet-phy@1 {
reg = <0x1>;
max-speed = <100>;
// interrupt-parent = <&gpio1>;
// interrupts = <25 IRQ_TYPE_EDGE_FALLING>;
};
};
};

kernel configuration:

# ethernet mdio
CONFIG_FSL_ENETC=y
CONFIG_FSL_ENETC_MDIO=y
CONFIG_FSL_ENETC_VF=y
CONFIG_FSL_ENETC_PTP_CLOCK=y
FSL_ENETC_HW_TIMESTAMPING=y

# Ethernet Gigabit PHY TI
CONFIG_DP83867_PHY=y

# CONFIG_IPV6 is not set

# TSN switch
CONFIG_TSN=y
CONFIG_ENETC_TSN=y

# Microsemi PHY
CONFIG_NET_VENDOR_MICROSEMI=y
CONFIG_MICROSEMI_PHY=y

# Felix Switch
CONFIG_MSCC_OCELOT_SWITCH=y
CONFIG_MSCC_FELIX_SWITCH=y
CONFIG _MSCC_FELIX_SWITCH_TSN=y
CONFIG_MSCC_FELIX_SWITCH_PTP_CLOCK=y

is my devicetree and kernle configuations okay?

Thank you for your help in advance

regards,

Uvi

Hi Fedor,

Thank you for your reply.

1) I am not allowed to send the schematics. Our hardware developer tested again with the board(PHY connections). it seems good. 

2) Please find the dts file below:

It is always reasonable to provide files as attachments and not inline.

Provided DTS seems to be incomplete - it lacks at least one closing "}".

Please try to generate LSDK composite firmware as described in the Layerscape Software Development Kit User Guide.
