hi all:
we designed a board.In our board, the MGBE UPHY6 port is directly connnct to switch BCM89586M with 10Gbe speed.it has some error. the 156.25M crystal oscillator works normally.
here is our dts file:
ethernet@6810000 {
compatible = “nvidia,nvmgbe”;
status = “okay”;
nvidia,disable-aspm-states = <0x0>;
nvidia,uphy-gbe-mode = <1>;
nvidia,phy-iface-mode = <0>;
nvidia,mac-addr-idx = <0>;
nvidia,pause_frames = <0>;
phy-mode = “10gbase-r”;
nvidia,max-platform-mtu = <16383>;
fixed-link {
speed = <10000>;
full-duplex;
};
here is the result of “sudo dmesg” | grep 681
