Open Cores MAC with a Nios II processor

Has anyone incorporated the Open Cores MAC into a Nios II design? I am working with a Nios II Evaluation board (Cyclone EP1C12) and used MaCo's Wishbone to Avalon conversion (www.maco-engineering.de) so that I could add the device in Quartus II. The design is compiled, but now I am working on software, and the drivers do not support the TDK 8Q2120C on board. Has anyone found/written a driver for the TDK? If not have you addapted it to another PHY and have any tips?

Thanks,

Jon

    I am useing the OpenCores MAC. An SOPC builder compatible version was included in a Linux development kit from Microtronix. The Stratix development board was equipped with TDK8Q2120, and I have sucessfully run Linux on that board.

    Hi,

    I am trying to set up a web server using Nios Development Board 1 running APEX20K200EFC484-2X soft-core processor. I have donwloaded the OpenCores Ethernet MAC core from MACO Engineering.

    I would like to built by own a Ethernet PHY module using National Semiconductor's DP83865 PHY. I got the schematic for the module DBGIG1 which supports Altera Cyclone and Stratix. But I am not sure whether it is also compatible with Altera Apex20KE.

    Anyone can provide me schematics of suitable Ethernet PHY circuit and if possible the reference designs in Quartus BDF file? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

    Also, I tried using the OpenCores Ethernet MAC Cores in SOPC Builder and when I generate it, the compilation fails when it comes to compilling the igor.c file in the lib folder. It has incompatible declarations with igor.h such as :

    In igor.h, we have "

    int nr_igor_reset(void *hardware_base_address, ns_plugs_adapter_storage *adapter_storage, ns_plugs_network_settings *s);

    "

    But in igor.c , they use ---------

    int nr_igor_reset(r32 hardware_base_address, ns_plugs_adapter_storage *adapter_storage, ns_plugs_network_settings *s)

    {

    r32 e = hardware_base_address;

    Instead of void *, it uses r32 ( an undefined type).

    then I included in the igor.h , the following:

    typedef unsigned char r8;

    typedef unsigned short r16;

    typedef void r32;

    But i noticed that there are some functions in igor.c which has type int for hardware_base_address, such as:

    int nr_mii_dump_registers(r32 hardware_base_address, ns_plugs_adapter_storage *adapter_storage)

    {

    int e = hardware_base_address;

    How should I solve this problem?Please , anyone, please enlighten me.

    Thank you very much,

    Yours sincerely,

    Makoto

    Thank you very much
