Ethernet data send and receive problem in AM1808 processor with LAN8710 PHY

Other Parts Discussed in Thread: AM1808, SN74LVC1G125

Hi,

I have custom board of AM1808 with external LAN8710 PHY connected on MII interface.

I am using linux-2.6.37-psp04.04.00.01 linux kernel and smsc-LAN8710 PHY (smsc.c) driver included in kernel.

I can see interface up in response of ifconfig command, once I give static IP to interface and try to ping with other network but ping is not working.

Please suggest your input.

Regards,

Jignesh

    Hi All,

    One more observation I am adding in to this forum.

    We use same kernel image (of custom board) on L138 EVM and able to get DHCP IP address.

    In EVM we can see MDC line of phy is connected to MAC MDIO_CLK threw SN74LVC1G125 Buffer (having BUFF_EN connected to GPIO2[6]).
    But in our custom board it is connected directly.
    Is it causing problem ?

    Regards,
