TDA4VM: MCU RGMII PHY connection

Part Number: TDA4VM

Hi TI members,

We are connecting TDA4 to a Marvell clause 45 PHY through MCU RGMII on our custome board.

After setting fixed-link in linux device tree, we can see the speed is 1000 and duplex is full using ethtool.

However, we still cannot ping to PC.

And, the phytool, which works fine without fixed-link, cannot read the correct register value.

Below is part of our device tree.

Is there any setting we missed?

&davinci_mdio {
        phy0: ethernet-phy@0 {
                reg = <2>;
                ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>;
                ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
        };
};

&cpsw_port1 {
    
        phy-mode = "rgmii-rxid";
        phy-handle = <&phy0>;

        fixed-link {
                speed = <1000>;
                full-duplex;
        };
    
};

Hi,

When using fixed-link, you don't have to give phy properties.
Could you test by removing "phy-handle"?

Vishal

Hi Vishal,

Thank you for the reply.

I removed phy-handle but the situation seems to be the same.

I also tried changing phy-mode from "rgmii-rxid" to "rgmii", but it still didn't work.

&cpsw_port1 {
        phy-mode = "rgmii";

        fixed-link {
                speed = <1000>;
                full-duplex;
        };
};

If I set compatible to "ethernet-phy-ieee802.3-c45", I cannot even see eth0 in linux.

&davinci_mdio {
        phy0: ethernet-phy@2 {
                compatible = "ethernet-phy-ieee802.3-c45";
                reg = <2>;
                ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>;
                ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
        };
};

Here are some question:

1. Is it normal that SMI fails when using fixed-link?

2. If I want to specify which phy driver should be used in the device tree,

should I configure the "compatible"?

Best regards,

Eric Chen

Hi Eric,

Sorry, forgot to ask you this initially.
'fixed-link' is used when doing MAC to MAC connection, is that what you are trying to achieve?

Hi Vishal,

I tried to modified the phy driver (drivers/net/phy/marvell.c) based on 88Q2122 API and used "compatible" to specify the driver,

but the link of phy is still not up.

Ethtool shows the interface is up, but the transceiver is internal, I am not sure if this is normal.

Can you try testing 100 Mbps mode.

0 Eric Chen9 over 5 years ago in reply to Vishal Mahaveer

Hi Vishal,

Thank you for the reply.

We tried to connect SoC to a Marvell PHY, which I believe is MAC-to-PHY.

So, we should use phy-handle instead of fixed-link and specify the driver in the phy subnode, right?

If it is, here is a problem.

Without fixed-link, the clock we measured at TDA4 side is 25MHz, not 125MHz for RGMII,

is this caused by the uncompleted auto-negotiation with PHY?

Best regards,

Eric Chen

Hi Vishal,

In Marvell's document, the PHY can only be set in 1000Base-T1 mode,

but we change the hardware setting and now the clock from PHY is 25MHz.

Here is the situation:

1. The registers of PHY shows that link status of PMA/PMD and PCS are up.

2. The registers of TDA4 shows that the RGMII link is up.

root@j7-evm:~# devmem2 0x46000030
/dev/mem opened.
Memory mapped at address 0xffffa3640000.
Read at address  0x46000030 (0xffffa3640030): 0x00000003

3. When I ping from PC to TDA4, PHY can get data from PC, but TDA4 cannot receive data.

4. When I ping from TDA4 to PC, PHY cannot get data from TDA4.

Below is the device tree setting now.

&davinci_mdio {
        phy0: ethernet-phy@2 {
                reg = <2>;
        };  
};

&cpsw_port1 {
        phy-mode = "rgmii-id";
        phy-handle = <&phy0>;
};

Could you check the stats registers?

Hi Vishal,

I checked all the registers of MCU_CPSW0_STAT0 and MCU_CPSW0_STAT1,

the values are all 0x00000000 without exception.

Hi Eric,

Let me check and get back if we support clause45 PHYs in Linux.

Vishal

0 Eric Chen9 over 5 years ago in reply to Vishal Mahaveer

Hi Vishal,

Is there any update?

Though the Marvell PHY uses clause 45, it also support clause 22 to access MMD registers.

I am now checking if the driver works fine and will also update the status here.

Best regards,

Eric Chen

TI__Mastermind 33360 points

Hi Eric,

We don't have support for Clause 45 PHY in TI driver, it should be used in C22 mode if the PHY supports it.
So this dts property "ethernet-phy-ieee802.3-c45" will not work.

Could you share the full boot log without this compatible field?

Vishal

Hi Vishal,

Sorry for replying so late, I've been working on SGMII recently.

With some modification to PHY driver, the RGMII PHY works fine now.

Thank you for all the support.

Best regards,
