Opencores MAC 10/100 Driver

Hi Everyone

Please feel free to use these files and/or comment on them. I've written them as a driver for the opencores mac solution. I have been using them with the lwip web server example that comes with the nios II installation and they seems to work.

I've attached a zip file with three files in it:

OpenCores_Ethernet_MAC_regs.h - contains the definitions of the registers inside the opencores MAC component.

OpenCores_Ethernet_MAC.c and the matching h file is the actual driver.

I've used these files in conjuction with files that come with the Nios installation, which I can't post here for obvious reasons. What I did was to make a copy of the altera_avalon_lan91c111 directory, name it accordingly and replace the file in the HAL\inc and HAL\src as well as the regs file in the inc directory with the file I've attached. I hope this helps someone.

Nir

    hello

    regarding question number 1, you are right and the mentioned h file should be included.

    regarding question number 2: i have not tested this code with ucos, so i can't say if it works and how.

    Hi Manish

    You should find it under your installation path, but in case you don't here is the one I have.

    I think i have my PHY file almost completed, but I have one last problem that I can't solve. How do I determine the Physical address of my PHY? I looked on my data sheet but all i can find is data on the 5 pins that control it saying that it supports 32 address (2^5). Is there set default for all these devices, or is this an arbitrary number since I only have 1 PHY device and 1 MAC device?

    //edit: I found on an ST data sheet (I'm using a TDK) that the register values are obtained on power on/reset by latching the address pins. Is this standard for all PHYs?

    Thanks,

    Jon

    you can get the alt_ethernet_dev.h from the lwIP.zip file available in the ip download section.

    @Nir:

    Nir,

    Do you know if this driver works with uCLinux or does it already have a driver?

    Thanks,

    Wade

    http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif Hello all & Nir

    Please take in mind that the S/W Auto negotiation process with the STE100 assumes that the STE100 device is Hardware configured (resistors pull-up & down). to enable auto negotiation at 100/10 Mbit full duplex (without H/W configuration) ANA and 100CTR registers should be modified before Autonegotiation restart.

    Thanks for everything

    We this work fine for us
