Hi,
I am currently using tds2sx for development, and the VSDK version is 03-06-00-00. I want to realize the Ethernet switch function of GMAC_SW module in Linux. The schematic diagram of Ethernet hardware connection is shown in the figure.
I tried the following：
１）In devicetree, I discribe the mac like this:
&mac {
status = "okay";
slaves = <2>;
active_slave = <0>;
pinctrl-names = "default", "sleep";
pinctrl-0 = <&rgmii1_default>;
pinctrl-1 = <&rgmii1_sleep>;
dual_emac;
};
&cpsw_emac0 {
phy_id = <&davinci_mdio>, <0>;
phy-mode = "rgmii";
dual_emac_res_vlan = <1>;
fixed-link {
speed = <100>;
full-duplex;
};
};
&cpsw_emac1 {
phy_id = <&davinci_mdio>, <2>;
phy-mode = "rgmii";
dual_emac_res_vlan = <1>;
fixed-link {
speed = <100>;
full-duplex;
};
};
&davinci_mdio {
status = "okay";
bcm89811: ethernet-phy@0 {
reg = <0>;
br_master;
};
ksz9031: ethernet-phy@1 {
reg = <1>;
};
};
2) Select the relevant option in the driver
CONFIG_TI_KEYSTONE_NETCP=y CONFIG_TI_KEYSTONE_NETCP_ETHSS=y CONFIG_TI_KEYSTONE_NETCP_PA_CORE=y CONFIG_TI_KEYSTONE_NETCP_PA=y CONFIG_TI_KEYSTONE_NETCP_PA2=y CONFIG_TI_DAVINCI_EMAC=y CONFIG_TI_DAVINCI_MDIO=y CONFIG_TI_DAVINCI_CPDMA=y CONFIG_TI_CPSW_PHY_SEL=y CONFIG_TI_CPSW_ALE=y CONFIG_TI_CPSW=y CONFIG_TI_CPTS=y CONFIG_TI_CPSW_PHY_SEL=y CONFIG_TI_CPSW_ALE=y CONFIG_TI_CPSW=y CONFIG_TI_CPTS=y
３）LINUX starts normally, and the startup log is as follows

5. Set the ip1 address of pc1 to 169.254.188.9, and the IP address of PC2 to 169.254.188.10
The ping test on PC1 shows that both 169.254.188.1 and 169.254.188.2 can be connected
On PC2, the ping test showed that 169.254.188.1 and 169.254.188.2 could not be connected
PC1 and PC2 cannot be connected
6, So, If I want PC1 and PC2 to connect, how do I modify my device tree and driver?
Thanks!
