AM335X: RGMII and RMII PHY configuration

Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3358

Hi

I would like to know if the CPSW configuration support two different PHY mode on the same CPSW ?

Our Hardware engineer connected the Atheros 8031 and SMSC LAN8710 to our Sitara processor.

/var/log/dmesg:[    1.220301] davinci_mdio 4a101000.mdio: phy[2]: device 4a101000.mdio:02, driver SMSC LAN8710/LAN8720
/var/log/dmesg:[    1.220315] davinci_mdio 4a101000.mdio: phy[4]: device 4a101000.mdio:04, driver Atheros 8031 ethernet

I am trying to configure the DTS in order to have both PHY working, one on ETH0 and one on ETH1 but I dont know how to proceed.

I have reused the cpsw_emac section of the am335x-evm-sk and the Atheros started to work, but for the SMSC LAN8710 I used the cpsw_emac section of the bone-common.dtsi and I dont see link on eth1

is there some one which can guide me about those two questions ?

1. Is this design can work ?

2. if Yes, how the cpsw_emac DTS section should look like ?

3. How the pin definition cpsw_default: should look like ?

4. Is the dual_emac mode has to be enabled ?

thanks in advance

    Hi,

    From your log file excerpt it seems that both PHYs register correctly on the MDIO. There are several things to check:
    1. The RMII interface needs external 50MHz clock.
    2. Pinmux configuration.
    3. eth1 needs to be brought up manually.
    4. Dual EMAC mode has to be enabled depending on your intended use case.

    Yes thank you.

    Just for confirmation, you're saying thRGMII and RMII on the same CPSW,

    Actually I have this in my DTS:

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

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

&cpsw_emac0 {
    phy_id = <&davinci_mdio>, <4>;
    phy-mode = "rgmii-txid";
    dual_emac_res_vlan = <1>;
};

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

    and somehow things started to work.

    root@linux:~# mii-tool -v eth1
eth1: negotiated 1000baseT-HD flow-control, link ok
  product info: vendor 00:01:f0, model 15 rev 1
  basic mode:   autonegotiation enabled

    And pinmux conf remaint the same:

    is it making sense ???

    Well, this shows both ports in RGMII mode.

    Hi,

    I am still stuck with this issue. My setup is as following:

    On ETH0 of the AM3358 I have the Atheros AR8031 and it works properly with no packet LOSS - connected in mode RGMII
    On ETH1 of the AM3358 I have SMSC LAN8710 connected in MII mode - with PACKET LOSS.

    - Can CPSW can handle two PHY working in different mode ? RGMII and MII ?
    - Secondly, in the SITARA Pinmux, I dont see a MII for ETH1, for example:
    PIN GMPC_A0 permits this mode: [GPMC_A0/GMII2_TXEN/RGMII2_TCTL/RMII2_TXEN/GPMC_A16/PR1_MII_MT1_CLK/EHRPWM1_TRIPZONE_INPUT/GPIO1_16].
    This PIN is connected to TXEN of the PHY, so the unique MII moe I can see is MODE1 meaning GMII2_TXEN, is it a correct assumption ?
    - Third, only when the PINs of SMSC are configured RGMII both PHY are working, but with PACKET LOSS on the SMSC, when I configure the cpsw_emac1 in phy-mode = "mii" no one of them is working, in term of Linux OS things seems to be OK, but no traffic is outgoing netheir incoming.

    So I am trying to figure out what is wrong in my configuration, why I select MII mode for cpsw_emac1, and why RGMII work for it (partly, since I am seeing some packet loss).


    Below my DTS:

    cpsw_default: cpsw_default {
    pinctrl-single,pins = <
    //RGMII Atheros
    /* Slave 1 */

    Hi,

    I need help to debug my issue.

    I have read dozen of threads on configuring RGMII and MII on U-boot and DTS in the TI forum, I have tried all of them, nothing is helping.

    My issue is as following:

    Our board is based EVMSK for everything except the ETH1 which is SMSC LAN8710 (used in the design of BBB).

    My DTS is as following:

    cpsw_default: cpsw_default {
            pinctrl-single,pins = <
                /* Slave 1 */

    &cpsw_emac1 {

        phy-mode = "mii";
      };

    The result is that I see LINK UP on  eth1 but no ping and no traffic is getting out neither received and suddenly the KERNEL reports a WARNING which also made ETH0 not working anymore.

    [  677.197982] device eth1 left promiscuous mode

    So, I need guidance to debug and how to check the validity of the PHY, it can be in u-boot or Linux, I have debugged the PHY register in both of them the issue remain the same.

    I almost sure the issue is somewhere in the hardware design, but I need your help to find the root cause.

    BTW, Strangely, when I declare "rgmii" for the ETH1, things starts to work but some packets are dropped..... very strange, the PHY is physically configured and connected using MII.....I am lost !

    Any direction, advice is welcome ,

    thank you very much in advance.

    Reviewing the latest DTS file and pin mux it appears that everything is setup correctly. I will need to discuss with a HW apps team member about the schematic setup.

    Could you please post your current Linux boot log as an attachment?
    After a reboot do not use eth0, run a few ping commands and then please capture the following ethtool commands and post as an attachment:
    - ethtool eth1
    - ethtool -S eth1
    Which Linux SDK are you using?

    The kernel Warn you are seeing appears to be that eth1 is not able to send packets. Most likely the issue that eth0 is ceasing to function is that all the TX descriptors are blocked on eth1 waiting to be sent. Something looks to be blocking the packets from leaving the mac.

    Monday is a holiday here so please be aware a response may not come until at least tuesday.

    One of our HW engineer found my mistake: TCLK had to be defined as INPUT and not OUTPUT

    WRONG:  0x58 (PIN_OUTPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a6.gmii2_tclk */

    the right configuration is:
                0x58 (PIN_INPUT_PULLUP | MUX_MODE1)    /* gpmc_a6.gmii2_tclk */

    the full Pinmux for MIi2 is:


                0x78 ( PIN_INPUT | MUX_MODE1 ) /* (U18) gpmc_be1n.gmii2_col */
                            0x70 ( PIN_INPUT | MUX_MODE1 ) /* (T17) gpmc_wait0.gmii2_crs */
                            0x74 ( PIN_INPUT_PULLUP | MUX_MODE1 ) /* (U17) gpmc_wpn.gmii2_rxer */

                /* Slave 2 */
                0x40 (PIN_OUTPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a0.GMII2_TXEN */
                0x44 (PIN_INPUT_PULLUP | MUX_MODE1)    /* gpmc_a1.GMII2_RXDV */

                0x48 (PIN_OUTPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a2.gmii2_td3 */
                0x4c (PIN_OUTPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a3.gmii2_td2 */
                0x50 (PIN_OUTPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a4.gmii2_td1 */
                0x54 (PIN_OUTPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a5.gmii2_td0 */

                0x58 (PIN_INPUT_PULLUP | MUX_MODE1)    /* gpmc_a6.gmii2_tclk */
                0x5c (PIN_INPUT_PULLUP  | MUX_MODE1)    /* gpmc_a7.gmii2_rclk */

                0x60 (PIN_INPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a8.gmii2_rd3 */
                0x64 (PIN_INPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a9.gmii2_rd2 */
                0x68 (PIN_INPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a10.gmii2_rd1 */
                0x6c (PIN_INPUT_PULLDOWN | MUX_MODE1)    /* gpmc_a11.gmii2_rd0 */

    thanks for your help  !
