DM8168 EVM eth1 giga interface problem

Other Parts Discussed in Thread: PMP

Hi,

 

I'm using DM8168 DDR3 EVM Rev-C with daughter board (TMDXVSDC8168) and ezsdk 5.02.01.59.

My app's main function is receving data from eth0 and save it to SATA HDD and retransmitting to eth1.

eth0 is work well with gigabit ethernet, but eth1 is not.

When I boot EVM eth1 connected to a gigabit port, no data transmission occurred.

At this time I unplug the eth1 cable and plug to a 100M port, data transmission is occurred.

After data transmission is occurred, I connect eth1 to a giga port again, data transmission is work-well.

 

When EVM is booted with eth1 connected 100M port, all data transmission is no porblem.

More exactly explan is;

When boot eth1 with giga port, I check ifconfig command, some ethernet packets are received from eth1.

But, no data is transmitted from my app, also no ping reponse to eth1 from outside.

At this time, I run 'ifconfig eth1 down' and the EVM is hangged.

Before EVM is hannged, I do unplug eth1 cable from giga port and replug it to giga port again,

no data transmission.

 

Help me.

    Can you provide kernel boot logs with eth1 connected with 1G and 100M.

  • Dear Mugunthan V N,

     

    Thank you for your reply.

     

    Before attaching the logs, I tell some more information.

    After posting this question, I tested the other daughter board rented by my local distributer.

    I got the same result, so this problem might be related with kernel.

     

    with regards

    Hyunho Youn

     

    Log 1. boot with giga-port

    Please apply the patch below to enable giga bit tx clocking for the phy.

    http://arago-project.org/git/projects/linux-omap3.git?p=projects/linux-omap3.git;a=commit;h=3228b1d8e5270ee56002e7f59d839ed8b6b85606

    with regards

    Mugunthan V N

  • Mugunthan V N

     

    Thanks you very much.

    My problem is solved by the patch.

     

    regards,

    Hyunho Youn

  • Mugunthan V N,

      Do I understand correctly:

    1. This patch configures the PHY chip to output 125mhz clock on the tx_clk line when it is in giga bit mode?   
    2. To operate in Gigabit mode, the EMAC requires clock pulses on tx_clk line.  Does it matter frequency signal it gets?
    3. In my case (custom hardware), it only operates in gigabit mode, so the tx_clk signal is not attached to anything.  Do you think hooking the tx_clk input to any clock would be sufficient to work around the problem?

    Thanks,

      Ryan

  • Hi,

      To follow up.  Feeding the TX_CLK pin with just about any clock does allow the chip to enter Gigabit mode.  We have it hooked to a 13.5mhz timer output pin of Davinci.  So, this works if you only need gigabit mode. 

    Ryan

     

  • Hi,

     

    I tested my app on 8168 EVM.

    And I did not fix or change HW. I did apply the patch to kernel source.

    After kernel patch, 100M/Giga ethernet connection is working well. (switching 100M/Giga is ok)

    I'm not HW engineer, so I have nothing to tell you about HW.

     

    Regards.

  • Hi,

      I'm glad the patch works for you.  From my understanding the patch works only for the EVM board, or probably any using the LSI ET1011 Gigabit PHY.  For my situation, we are using a different PHY (Micrel KSZ9021GN), which does not work with the patch.  My PHY does not have an option to output a clock on tx_clk lines when in gigabit mode.  So, I'm trying to find an alternative solution.  As I mentioned, at minimum we can hook the tx_clk line to a clock (instead of the PHY) and use only Gigabit mode.  I've verified this hack.  I'm still searching for a solution which allows 10/100/1000 Mbps operation.

    Thanks,

      Ryan 

  • Hi, Ryan!

    We have same PHY (KSZ9021GN) chip as you and it didn't work on our custom board not in any mode. (At u-boot stage I see error message: WARN: emac_send_packet: No link) But from u-boot command line I can read/write PHY registers (mii). Do you have any decision of your problem? May be it is help to me too. Thank you.

  • Hi Mugunthan

    we also meet problem about net,

    we develop using dvrrdk 2.80 dm816x evm board,

    the problem is that if we connect 8168 board with PC through switch or router ,link is up and stability,

    if we connect PC and 8168 board directly ,the link is up and down all the time

    Print like
    Link is up

    Link is down ,

    and we test 4 Pc, only one is works well, other 3 Link is up and down all the time

    So how can net link not stability ?

    best regards

    xavier 

  • hi Vladimir

    But from u-boot command line I can read/write PHY registers (mii).

    ==> could you tell me how to do that ??

    Thanks...

  • Hi, Jack!

    You should use mii command from u-boot. If it is not enabled - add in your board config file this macro and rebuild u-boot:

    #define CONFIG_CMD_MDIO
    #define CONFIG_MII
    #define CONFIG_CMD_MII

    Example of using:

  • hi Vladimir,

    great thanks fro your reply.

    I got the same result as yours.

    And I want to got following, because I have two port and I just want to use the second port...how could I do that??

    Current device: 'GENERIC @ 0x02'

  • Hi, Jack!
    Sorry, but I can't tell you more exactly, because I don't work with two ports simultaneously. I suppose that you need set current MII device via command mii device <devicename>, and your PHY must have a different MDIO addresses. In command mii read <addr> <reg> you can try using different MDIO addresses of PHY.
