Part Number: AM5708
Tool/software: Linux
HI ALL:
Just now we develop a custom am5708 board.
But There is some issues about the CPSW, It can not work.
Our network diagram is like below:
AM5708 chip CPSW(emac0) ----> Nothing.
AM5708 chip CPSW(emac1) ----> RTL8201CP.
We use MII mode between the CPSW(emac1) and the RTL8201CP chip.
Now the MDIO bus can read the RTL8201 chip and can get the Link info such as:
cpsw 48484000.ethernet eth1: Link is Up - 100Mbps/Full - flow control rx/tx
However we can not get the ip address from the router when using the udhcpc tool.
We also used the Oscilloscope to measure the mii1_txen, mii1_txd[3:0] singal, while test no signal.
So Anyone can help us.
Our devicetree is below:
&mac {
status = "okay";
dual_emac;
};
&cpsw_emac0 {
phy-handle = <&phy0>;
phy-mode = "mii";
dual_emac_res_vlan = <1>;
};
&cpsw_emac1 {
phy-handle = <&phy1>;
phy-mode = "mii";
dual_emac_res_vlan = <2>;
};
We use Processor 4.3 sdk
Thanks
regards
