hi I'm porting dp83tc811 on mdm9607 (linux3.18),but it can not work when ping pc and mdm9607,

my step:

1:

  • Hi,

    Few questions:

    1. Do you see link up with Link Partner ?
    2. What is the interface on MAC you are using ?

    Can you try doing a MAC loopback to confirm MAC interface with Phy is looking good ?

    Regards,
    Geet

    hi 
    hi loopback is ok ,when looback failed ,The tx of the phy on our hardware connects the rx of the CPU,The rx of the phy on our hardware connects to the tx of the CPU.loopback is Ok after changing the connection mode-----The tx of the phy on our hardware connects the tx of the CPU,The rx of the phy on our hardware connects to the rx of the CPU.but in normal mode ,ping pc and mdm9607,it's still failed,pls give me some advices

    Hi,

    You mentioned loopback is OK. Just to be clear here,

    1. Phy was configured in MII Loopback.
    2. Packets were trasnmitted from CPU.
    3. All the packets were recieved back to CPU.


    Next thing we need to check is analog interface on the line side.

    1. Do you see Link-UP when connected to Link Partner Phy ?
    2. Can you configure the Link Partner Phy in Reverse loopback and send packets from the CPU ? and check whether MAC is able to recieve the packets back ?

    hi now the mdm9x07 can ping to pc

    1:insmod /usr/lib/modules/qcom_emac.ko 
    2:echo 1 > /proc/sys/net/ipv4/conf/eth0/arp_ignore 
    3:ifconfig eth0 
    4:ifconfig eth0 -arp 
    5:ifconfig eth0 down 
    6:ifconfig eth0 hw ether 00:80:48:BA:d1:30 
    7:ifconfig eth0 up 
    8:ethtool -s eth0 autoneg off speed 100 duplex full 
    9:ifconfig eth0 192.168.255.10 
    i must add : 
    echo 1 > /proc/sys/net/ipv4/conf/eth0/arp_ignore and 
    :ifconfig eth0 -arp 
    otherwise ping is failed,this why?

    and in linux3.18

    in dp8ctc811.c

    must change phy_write_mmd to phy_write_mmd_indirect

    and change phy_read_mmd to phy_read_mmd_indirect.

    in dp83811_driver must add .read_status = genphy_read_status,

    We will take an note of above information and inform linux driver team. Let me know if any other additional help you need.
