Tool/software:
Hello TI Team,
We have used DP83TC814R-Q1 PHY with AM64xx CPU.
Our DTS Configuration looks like below:
&cpsw_port1 {
/*bootph-all;*/
status = "okay";
phy-mode = "rgmii-rxid";
phy-handle = <&cpsw3g_phy1>;
// fixed-link {
// speed = <100>;
// full-duplex;
// };
};
&cpsw3g_mdio {
bootph-all;
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&cpsw_mdio0_pins_default>;
cpsw3g_phy1: ethernet-phy@0 {
reg = <0x0>;
ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>;
ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
// fixed-link {
// speed = <100>;
// full-duplex;
// };
};
};
With this configuration, we are able to see the CPSW is able to identify which PHY is connected. And link also we are able to detect.

If you can see the signal quality is also good, but we are not able to receive any packets.

If you look at the dts configuration we have kept fixed link mode configuration at 2 places. We tried to configure at respective place as well as at both place, but it is not working.
Kindly share some insights what can be changed to get this working.
With regards,
