ls1028 switch doesn't work

afterdream — Thu, 26 Aug 2021 05:39:34 GMT

hi，

My ls1028 hardware sets the switch‘s four port as sgmii-2.5G，setting the serdes1 sgmii-2.5 by rcw=7777

but，running the order “ifconfig -a”，I cannot find swp0 swp1 swp2 swp3

and，the path /sys/bus/pci/devices/0000:00:00.5/net/ doesn't exit，not having swp0-3 also

That's why？

May I missed some other software configuration？

tks！

For Kernel configuration, please refer to the following.

CONFIG_MSCC_OCELOT_SWITCH=y

CONFIG_NET_DSA_MSCC_FELIX=y

CONFIG_FSL_ENETC_MDIO=y

For dts configuration, please refer to mscc_felix_ports device node definition in arch/arm64/boot/dts/freescale/fsl-ls1028a-qds-7777.dts in Linux Kernel source code.

fragment@1 {
target = <&mscc_felix_ports>;
__overlay__ {
port@0 {
status = "okay";
phy-handle = <&slot1_sxgmii0>;
phy-mode = "2500base-x";
};

port@1 {
status = "okay";
phy-handle = <&slot1_sxgmii1>;
phy-mode = "2500base-x";
};

port@2 {
status = "okay";
phy-handle = <&slot1_sxgmii2>;
phy-mode = "2500base-x";
};

port@3 {
status = "okay";
phy-handle = <&slot1_sxgmii3>;
phy-mode = "2500base-x";
};
};
};

hi，

几个问题请假一下：

（1）ls1028 enetc的port2 和 switch port4内部是mac2mac连接的，但是fsl-ls1028a.dtsi中，为什么使用的fixed link不一样呢？

（2）通过dmesg查看启动log，发现dsa交换机在注册的时候出错，难道enetc port2在连接switch port4存在问题，这个一般是什么问题？

[    3.319766] 000: fsl_enetc 0000:00:00.2 eth1: error -22 setting up slave phy
[    3.320131] 000: mscc_felix 0000:00:00.5: Failed to register DSA switch: -22
[    3.320488] 000: mscc_felix: probe of 0000:00:00.5 failed with error -22

（3）enetc port2接口模式需要设置吗
