Opencores MAC 10/100 Driver

[Altera_Forum]

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

Hi everyone 

 Somebody braught to my attention that the zip file I've posted does not contain an STE100P.h file that one of the source files include. Initially It actually didn't include this file, since I used the STE100P phy chip in my project, but you can use different chips to do the same job. However, since there is no prevention for me to post this file as well, here is an ammended zip file with the STE100P.h file in it.  Sorry for that  Nir

Hi nir, 

 I use Mtx Cyclone Dev.Board, and the OpenCores MAC 10/100 Core can be used on board.  But I do not know clearly how to implement the simple_socket_server project by using the Mac and your driver under Nios II IDE.  Can you give me some detailed information or guide?  Thank you very much.

Hi everyone, 

 I'm using a Cyclone board with an Opencores MAC 10/100 IP ver. 2.0 and a National DP8847 PHY.  I wrote the application using nir's driver, but when I run it the driver stucks when accessing the MAC MODE register: the sthio instruction does not return.  Any idea about what could be wrong with my design ?  Thanks a lot

[Altera_Forum]

Sorry, this is also a test, 

forgot it

Hi LiangYi 

 What kind of PHY chip do you have on the Mtx board ?  Nir

[Altera_Forum]

Hi nir, 

 The PHY on my Mtx.board is TDK 78Q2120-64T.  LiangYi.

Hi 

 The driver I've written works with the ST PHY chip called ST100P. If you want it to work with your device, you'll need to create a file similiar to the ST100P.h file for you device, in which you should define the device's registers. YOu also need to make sure you perform any required changes to make Opencores_Ethernet_Mac.c configure the phy chip correctly (look in read_phy, write_phy and configure_phy functions as in any ither function you think may need a change.  I hope this helps.  Nir

[Altera_Forum]

I will try it. 

 Thank you very much.

This is defined in file "OpenCores_Ethernet_MAC.h"  Here is the code excerpt from file "OpenCores_Ethernet_MAC.h" # ifndef __ucosii__ # include <stdlib.h># include <stdio.h># include "alt_types.h"# include "system.h"# include "alt_ethernet_dev.h" . . . .    2) In case of ucosII is there, I couldn&#39;t understand from dev structure is initialized. in following macro. Also how routines for initializing Ethernet Ip and Recive Data from interface are initialized if this dev structure is not initialized?    # else  # define OPENCORES_ETHERNET_MAC_INIT(name, dev)  # define OPENCORES_ETHERNET_MAC_INSTANCE(name, dev)  # endif /* __ucosii__ */

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&#39;t say if it works and how.  Nir

Hi Manish 

 You should find it under your installation path, but in case you don&#39;t here is the one I have.  Nir

Sorry for that.

I think i have my PHY file almost completed, but I have one last problem that I can&#39;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&#39;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

[Altera_Forum]

Hello Jon 

  I have to work with TDK PHY.   Can you send me TDK files?     Thanks, Ilya

[Altera_Forum]

Hello all 

  Unfortunately I didn&#39;t find "alt_ethernet_dev.h" file and couldn&#39;t download it.  I&#39;ll appreciate somebody&#39;s help.   Thanks, Ilya

[Altera_Forum]

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

 @Nir: Thank you very much... i get an error because my bus width is 16, how do i get it to 32?

[Altera_Forum]

Nir, 

 Do you know if this driver works with uCLinux or does it already have a driver?  Thanks,  Wade    --- Quote Start ---  originally posted by nir@Jan 4 2005, 04:49 PM hi everyone  please feel free to use these files and/or comment on them. i&#39;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&#39;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&#39;ve used these files in conjuction with files that come with the nios installation, which i can&#39;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&#39;ve attached. i hope this helps someone.  nir <div align='right'><{post_snapback}> (index.php?act=findpost&pid=3675)  --- quote end ---    --- Quote End ---

Hi everyone, 

where can I download the ip core?   Is it www.opencores.org?   Thanks! http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/laugh.gif

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 Avi
