DE4 Simple Server Socket example

Hi, 

I have an Altera DE4 Development and Education Board. I’m using Quartus II 11.0. 

I’m trying to run “Simple Socket Server (RGMII)” example. 

This is the ‘Nios II Console’ output:

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.

Can you help me, please?

It seems your flash memory stored invalid ip and mac addresses. 

In your SSS project you should have a function named get_ip_add(). 

Try forcing *use_dhcp = 0 and momentarily set a well known static ip address. 

In the same file you should also find a get_mac_addr() function: force it returning a fixed mac address, not ff ff ff ff ff ff  

If everything works this way, debug into these functions in order to discover why you can't retrieve the correct addresses from flash.

Hi Cris72, 

thank you for your support. 

I already tried to do what you suggested me, but without success. 

I also tried to do a restore of the flash with the factory settings, but I have not succeeded.

Forgive me if these are stupid questions, but I don't know your expertise level with network and embedded systems: 

- are your sure the DE4 board is actually initializing with valid mac/ip addresses, as I said above? 

- did you try a simple ping before testing the telnet connection? 

- did you check your pc network configuration? did you configure the same subnet?

Hi Cris, 

- I'm not surethe DE4 is initialized with valid mac/ip addresses. In this regard, I tried to do a reset to factory settings but I did not succeed. 

- Yes, I tried pinging, but without success. 

- Yes, I modified the file simple_socket_server.h to assign static network parameters. 

 

BR, 

Umberto
