DP83867IS: Cannot go to LINK status after eth0 up under 1000Mbps

Chase Jeong
Mastermind 7645 points
Part Number: DP83867IS

Hello TI experts,

my customer made their own PCB with DP83867IS, and they have some problems now.

first they had a trouble with test their own PCB, so they deleted "PHY_1000BT_FEATURES" in device driver, and connected their PCB to PC using LAN cable.

and they succeed with 100Mbps communication.

After those step, they restored "PHY_1000BT_FEATURES" again in device driver.

they succeeded with eth0 up, and going to LINK status. but PC side presents 100Mbps link, and DP83867IS side presents 1000Mbps link.

and it seems that these 2 module communicate with 100Mbps.

is there any check points that can solve this problem? (register setting or device driver, or other things)

I attach 2 register dump files. It is dumped after "ifconfig eth0 [ip addr] up" command, before connecting cable. after connecting cable, it does not work as 1Gbps.

    Hi Chase,

    You should not be modifying the driver structure to force speeds. Instead, use register writes to disable auto-negotiation and select the desired speed in register 0x0000. Please restore the driver to its original state.

    You said the PHY is advertising 1000Mbps as desired, but the PC side is only advertising 100Mbps. The expected outcome, then, is that the devices will link up in 100Mbps. You must set the PC side to advertise 1Gbps if you would like them to auto-negotiate to 1Gbps. Is there something preventing you from doing this?

    Thanks,

    David

    Dear David,

    Thank you for your support.

    I think the setting in register 0x0000 is right, because i confirmed 0x1140 in register dump file. (it is set as 1000Mbps.)

    and I will ask to my customer to check PC side for something wrong.

    And here are more question.

    1. Could you guide me about your test procedure for 1000Mbps communication?

    2. Is there something wrong in the register dump which disables 1000Mbps communication?

    Best regards,

    Chase

    Dear David,

    Here is one more request, could you review the schematic of DP83867?

    we want to know if there are any points to concern about this issue.

    Best regards,

    Chase

    Dear David,

    Here is the feedback from my customer.

    PC side which you asked is okay, 1000Mbps communication confirmed when connected with other PC.

    so please review the schematic, and check the register dump, and provide a test procedure. Thanks.

    Best regards,

    Chase

    Hi Chase,

    Please send me a register dump with the device linked up in 100Mbps. 

    For test procedure, try connecting the DP83867 with several other link partners, including another DP83867. Try with auto-negotiation on and also manually forcing 1000Mbps on both sides of the link.

    I will review the schematic and provide feedback within 5 business days.

    Thanks,

    David

    Hi Chase,

    Here are my comments regarding the schematic:

    1. Power supply decoupling is inadequate. Please ensure the power pins have the capacitors according to section 10 of the datasheet, and that the caps are placed as close to the pins of the PHY as possible. I cannot see the VDDIO or VDDA1P8 LDOs in the images you sent.

    2. Does MDIO have a 2.2k pullup resistor?

    3. JTAG pins (20-23) should be left floating if unused. 

    4. The magnetics used are not compliant with the requirements listed in section 9.2.1.1 of the datasheet. See note (1) "Each center tap on the side connected to the PHY, must be isolated from one another and connected to ground via a decoupling capacitor (0.1 µF recommended)."

    I believe fixing the above issues will solve your problem. 

    Thanks,

    David
