Ethernet initialization trouble

Altera_Forum · ‎05-17-2011

Hi all,

I am using Quartus II 10.1,Nios IDE 10.1 and a custom board,based heavily on Arria II development board.Currently i am trying to setup a GigE connection.I have a heavy suspicion on PHY working state and/or hardware connection,since i don't see blinking leds of rx/tx and 1000 link.As offered here in the forum on similar occasions,first of all,i should test the connection with simple socket server program.I am using RGMII connection.I have tried both the regular and RGMII versions of simple socket server program.This is the output that i get from the console :

prep_tse_mac 0

Can't read the MAC address from your board (this probably means

that your flash was erased). We will assign you a MAC address and

static network settings

Please enter your 9-digit serial number. This is printed on a

label under your Nios dev. board. The first 3 digits of the

label are ASJ and the serial number follows this.

Any help on resolving/understanding the issue would be welcome .

Thank You

First of all make sure all PHY pins are correctly driven; in particular check reset and clock signals.

Then you can probe or Signaltap the mdio interface in order to see if PHY is "alive" and if it answers to hal driver requests.

This is a simple two wire serial interface. See page 4-42 of TSE user guide for more info.

That's what I have. Is a November 2009 version; probably you have a different one.

Search the contents for "MDIO" or "PHY Management"
