Linux/AM3352: DP83867 PHY configuration issue

Ildar Sadykov
Prodigy 120 points
Part Number: AM3352
Other Parts Discussed in Thread: TIDA-00204

Tool/software: Linux

Hi.

In our board used schematic (Scheamtic and PCB) from TIDA-00204 in case of RGMII PHY connections.

I read a lot of threads, but still can not confugre PHY in .dts file correctly (or, may be, trouble in somewhere else) and ethernet link not worked.

This is kernel log:

    Thanks for posting the DTS file, console log and ethool results. Looking at the console log and the DTS file for the mac interfaces, one PHY is answering at address 0. You have two PHYs configured and they both have the same PHY address, one of these has to change. Each mac interface PHY must be unique on the MDIO bus. Please review your PHY addressing and reply if that fixes your problem.

    &cpsw_emac0 {

    phy_id = <&davinci_mdio>, <0>; <--- the <0> is the phy address....
    .......
    };



    &cpsw_emac1 {

    phy_id = <&davinci_mdio>, <0>; <---- each mac has its own phy and the phy address must be unique.
    ......
    };

    Hi!
    Thank uoy for your answer.

    Yes, im tried it, but it also not worked:

    .dts piece:

    &mac {
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&cpsw_default>;
	pinctrl-1 = <&cpsw_sleep>;
	status = "okay";
};

&davinci_mdio {
	pinctrl-names = "default", "sleep";
	compatible = "ti,cpsw-mdio","ti,davinci_mdio";
	pinctrl-0 = <&davinci_mdio_default>;
	pinctrl-1 = <&davinci_mdio_sleep>;

    Also I was tried to set this configuration:

    &mac {
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&cpsw_default>;
	pinctrl-1 = <&cpsw_sleep>;
	dual_emac = <1>;
	status = "okay";
};

&davinci_mdio {
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&davinci_mdio_default>;
	pinctrl-1 = <&davinci_mdio_sleep>;
	ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
	ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
  ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
  ti,min-output-impedance;
	status = "okay";
};

&cpsw_emac0 {
	phy_id = <&davinci_mdio>, <0>;
	phy-mode = "rgmii-txid";
	dual_emac_res_vlan = <1>;
};

&cpsw_emac1 {
	phy_id = <&davinci_mdio>, <16>;
	phy-mode = "rgmii-txid";
	dual_emac_res_vlan = <2>;
};


    But effect was same: 

    After kernel bootlog line "Configuring network interfaces... " all LEDs on PHY turn off and after that I can start it only by "/etc/init.d/networking stop" and "/etc/init.d/networking start" and other posted above.

    Hi,
    Thanks for posting the interface statistics. These numbers here are concerning that are listed in the statistics. These can typically indicate board level or timing issues unfortunately. The RX CRC errors indicate something between the PHY and MAC and the RX Code errors also point to the PHY seeing Symbol issues and is reporting to the MAC the packet is missing a nibble or more.

    Rx CRC Errors: 2
    Rx Align/Code Errors: 120

    I will need to discuss with a fellow team member because in the davinci MDIO structure you have set a timing delay the PHY mode is required to rgmii-txid for AM335x devices. This could be a double delay by adding delay to the PHY too. Is the link partner showing issues with RX also? The problem though you are seeing looks to be on the receive side on your board.

    Best Regards,
    Schuyler

    Hi. Thank you for your answer

    I resolve the problem.

    It was a hardware+configuration problem.

    I change board (it was corrupted) and found a valid dts config file.

    Valid davinci_mdio device tree config for my "TIDA-like" board (delays may be wrong, because of now I operate only at 100Mb speed):

    &mac {
    pinctrl-names = "default", "sleep";
    pinctrl-0 = <&cpsw_default>;
    pinctrl-1 = <&cpsw_sleep>;
    dual_emac;
    status = "okay";
};

&davinci_mdio {
    pinctrl-names = "default", "sleep";
    compatible = "ti,cpsw-mdio", "ti,davinci_mdio";
    pinctrl-0 = <&davinci_mdio_default>;
    pinctrl-1 = <&davinci_mdio_sleep>;
    status = "okay";

    Hi,

    The fellow team member is out of the office today, we will discuss the timing selections for the PHY.

    Our team does not support the TI PHY that you are using so we will not be able to comment on the actual PHY settings. The rgmii-id will probably need to be rgmii-txid as that is the only mode supported by the AM335x for Gbps speeds.

    My colleague will need to see trace length data for the layout between the MAC and the PHY I believe, I could be wrong though. If you have that information could you please attach it to the post?

    Regards,
    Schuyler

    Thank you for your answer.

    Its interested, but both options "rgmii-txid" and "rgmii-rxid" not worked. Only "rgmii-id" provide a connection.

    Trase lengths:

    Wire Length, mm
    RGMII1_RXCLK 30.131
    RGMII1_RXCTRL 30.100
    RGMII1_RXD0 30.127
    RGMII1_RXD1 30.125
    RGMII1_RXD2 30.125
    RGMII1_RXD3 30.125
    RGMII1_TXCLK 29.966
    RGMII1_TXCTRL 30.767
    RGMII1_TXD0 30.029
    RGMII1_TXD1 29.938
    RGMII1_TXD2 29.932
    RGMII1_TXD3 29.972

    I was tested connection quality for 1Gbit speed and it have a problem: 

    Rx CRC Errors quantity is about 40 per minute (during file download)

    Rx Align/Code Errors quantity is about 35 per minute  (during file download)

    I was tried all availabled settings (connection was established with RX_DELAY value from 1.50ns to 3.75ns) and most "good" value is 3.25ns (Rx CRC Errors quantity is 25, Rx Align/Code Errors quantity is 30).

    Unfortunately, we havent oscilloscope which required with http://www.ti.com/lit/an/snla243/snla243.pdf and we cant measure RGMII Delay manually.

    Hi,
    Thanks for posting the trace lengths. We will post a review of the trace lengths tomorrow, I apologize for the delay.
    Regards,

    Hello,

    If I understand correctly, you now have successful 10/100Mb connections but 1000Mb still exhibits CRC and code align issues.

    This points to a timing issue on the interface. Did you perform a timing analysis of the interface prior to PCB layout? Your traces are very short @ ~1" so it may not be possible to meet the MAC+PHY setup and hold for Gigabit operation.
