LS1043A FMan-RGMII-PHY Interface Issue

[j_wallace]

Hi Experts.

We have a custom LS1043A rev1.1 custom board which has RGMII1 connected to a Marvell PHY (88e1512). The PHY 25MHZ clock is generated by a dedicated oscillator. u-boot on this board is based on LSDK1806. The interface is not working. ping always fails. I replaced the PHY driver with SDK2.0 driver and now ping works but tftp tranfer hangs with timeout error. There is another Ethernet chip connected to PCIe but it is not used for now so don't care. 

Has anyone experienced such a behaviour?

Thanks.

Hello j_wallace,

Linux Kernel in LSDK 1806 has already provided driver for Marvell PHY 88e1510, you could boot the target board to go to Linux to do more verification. If the networking interface works normally, please modify PHY driver in u-boot according to Linux Kernel source code drivers/net/phy/marvell.c.

Please configure CONFIG_MARVELL_PHY in Linux Kernel configuration file, in the dts file, please modify the dts file as the following.

ethernet@e4000{

               phy-handle = <&rgmii_phy1>;

               phy-connection-type = "rgmii-txid";

}

mido@fc000 {

                rgmii_phy1: ethernet-phy@1 {

                                reg = <0x0>;

                }

        ... ...

 };

Have a great day,
TIC

Hi, thank for your response

1) The RGMII interface is not working at Linux level too. It looks like the problem is at RX side. If I ping my worstation I can see in Wireshark that the workstation is responding but my LS1043A board is not seeing the reply. Also I saw that the RGMII interface is taking the I210 MAC address while I set another one in the device tree. I tried to change "phy-connection-type" to "rgmii-id" but it does not work better.

&fman0 {    

    ethernet@e4000 {
        phy-handle = <&rgmii_phy1>;
        phy-connection-type = "rgmii-txid";
        local-mac-address = [00 04 9F 04 03 CA];
    };

    mdio@fc000 {
        rgmii_phy1: ethernet-phy@0 {
            reg = <0x0>;
        };        
    };   
};

2) So far, the LSDK1806 Linux kernel hangs on our custom board so I'am running a kernel.org one:

pub/scm/linux/kernel/git/leo/linux - Git at Google

I have already set CONFIG_MARVELL_PHY

3) FM1@DTSEC9 is not used on our board. Should I explicitly disable It in u-boot?

Best regards

[j_wallace]

I managed the LSDK1806 Linux kernel to boot on my custom LS1043A board but same behaviour. ping fails though the request successfully reaches the remote host.

We are facing similar issue with our card.  have u able to resolve the issue. Kindly help.

Hello j_wallace,

Please configure MAC addresses in u-boot environment as the following.

eth1addr=00:e0:0c:00:a9:01
eth2addr=00:e0:0c:00:a9:02
eth3addr=00:e0:0c:00:a9:03
eth4addr=00:e0:0c:00:a9:04
eth5addr=00:e0:0c:00:a9:05
eth6addr=00:e0:0c:00:a9:06
eth7addr=68:05:ca:0f:14:06
ethaddr=00:e0:0c:00:a9:00

Please use mdio command under u-boot to read PHY register Rx status information.

mdio read <phydev> [<devad>.]<reg> - read PHY's register at <devad>.<reg>

Have a great day,
TIC
