LS1028: could not attach to PHY

yuvarajesh_vall — Mon, 16 Mar 2020 09:35:07 GMT

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

Please provide:

1) connection schematics as searchable PDF

2) complete DTS

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.

Hi Fedor,

Sorry for dts file not attached. Please find the corrected and attached dts file.
