DP83640: Linux Device tree node definition

Robert Henson

Part Number: DP83640
Other Parts Discussed in Thread: AM3352, TPS65910

We are trying to use a DP83640 PTP transceiver with an AM3352. The AM3352 has linux kernel version 4.4.32 and device tree is V1.

Can anyone point me to an example of how to configure device tree such that am3352 MAC will recognize DP83640?

we are getting these messages in dmesg that indicate it's not seeing the PHY

[ 1.250012] davinci_mdio 4a101000.mdio: davinci mdio revision 1.6
[ 1.256163] davinci_mdio 4a101000.mdio: detected phy mask fffffffd

[ 1.292993] cpsw 4a100000.ethernet: cpts: overflow check period 850

And these messages that indicate the PHY is not present

Hi Robert,

Thank you for getting in touch with us.

Here is an example driver we have developed for DP83640 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/phy/dp83640.c

Hi Gokul,

I think the issue we are having is with the node definitions in the device tree. I believe the driver is ok. With that said, I went ahead and replaced the one I had with the one you supplied. It did not change the behavior. I am able to access the PHYTER using mdio-tool and verified that reading registers 0x02 and 0x03 provide PHY_ID of 0x20005ce1 so, I think the driver is working ok.

But, as the snippets from dmesg above show, in the first snippet line 4 indicates the correct driver being used. And in the second snippet, line 4 identifies the correct PHY (based on PHY_ID) but the very next line indicates PHY not found. and I researched line 6 and err -19 indicates "device not present". so I really feel it is our device tree that is not correct.

Do you have any information on device tree set up for DP83640 PHYTER? (note our device tree is V1)

Thank you!

Robert Henson

Hi Robert,

The AM3352 team is better to answer your question. Let me loop in them to answer your question.

Hi,

Which TI SDK are you using? Could you please attach the DTS file and if possible the portion of the schematic schematic that shows the CPSW and the PHY?

Best Regards,

Schuyler

TI SDK is 4.4 I believe and dts is below and schematic is attached

Any other information you need besides the below?

Hi,

One suggestion is to try defining the ethernet1 node in the davinci_mdio node. For example, the two nodes would have this heirarchy. I am just showing the node names and not the full node elements.

&davinci_mdio {

ethphy1: ethernet-phy@1 {

};

Best Regards,

Schuyler

I modified the dts file to embed the ethernet node within the davinci_mdio node as follows

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

ethphy1: ethernet-phy@1 {
  compatible = "NatSemi,DP83640";
  device_type = "ethernet-phy";
  reg = <1>;
  dp83640,perout-pins = <2>;
  dp83640,extts-pins = <3 4 8 9 10 11>;
  dp83640,calibrate-pin = <1>;
  status = "okay";
  };

};

The errors in dmesg are still the same as what is posted above.

specifically

[ 1.266475] cpsw 4a100000.ethernet: No slave[1] phy_id, phy-handle, or fixed-link property

and

Hi,

The DT node looks good. Could you please attach (not cut and paste) the complete boot log? Also after booting could you please attach the output of ethtool eth0 please?

Best Regards,

Schuyler

Hello Robert

Schuyler is out of office for the next 2 weeks. Looks like he missed addressing this post earlier.

I will see if this can be assigned to someone else, but chances are this may need to wait till late first week of July. We regret the delay

Regards

Mukul

Hi,

The boot log shows that the PHY is reporting not found but ethtool is reporting that eth0 has a link at 100Mbps detected. Are you connected to a network and obtaining an ip address from a DHCP server?

The earlier boot shows the PHY being identified as a national semiconductor and now only this ID 0x20005ce1 is being printed. What is the expected PHY ID of the PHY on the board?

Best Regards,

Schuyler

0x20005ce1 is the correct PHY ID for the DP83640 PHYTER

0 Robert Henson over 3 years ago in reply to Robert Henson

Prodigy 10 points

we are connected to a network (with a DHCP server) but we are not obtaining an IP address

The PHY is establishing the link layer connection. However, scoping the bus from the processor to the PHY shows no activity on the data lines or data available line.

0 Schuyler Patton over 3 years ago in reply to Robert Henson

TI__Mastermind 40690 points

Hi,

Does the PHY clock lines show any activity? This could be a pin mux issue. Was the pin mux tool used for creating the DTS pin mux for cpsw port in use?

What does "ethtool -S eth0" show? This shows the MAC statistics. This command will list counts for RX errors, packets TX/RX counts etc. The first checkpoint is that Ideally we expect the TX frame count to be non-zero to show packets being sent. What you have measured though says that the count will likely be zero.

If the pin mux is incorrect no data will be sent or received. It looks like the MDIO is working as expected since it indicates a link and link speeds.

Best Regards,

Schuyler

Hi Schuyler, Thank you for the reply!!!

I did not use a pin mux tool. I "inherited" a partially complete DTS file and modified it following the pin mux config as defined in the AM3352 data sheet.

Currently the Pin Mux for cpsw looks like

               pinctrl-single,pins = <

Hi,

The MAC level statistics confirm your observation on the bus. The first thing to look at is that the TX frame count is zero. Are you seeing any NETDEV watchdog timeouts?

Could you please post ifconfig -a?

Best Regards,

Schuyler

Hi,

I am not sure what to recommend next. Could you please post a scope capture of the tx clock line between the MAC and the PHY?

Also please remove the cable and use ethtool to verify the link goes down and then plug in the cable and verify the link is re-established?

Best Regards,

Schuyler
