simple socket server example on cyclone II dev kit

Altera_Forum · ‎10-05-2009

Hi,

I want to use the simple socket server example with the cyclone II dev kit. I compiled it and then I run it. In the file simple_socket_server.h I defined the IP-adress like this:


#define IPADDR0 192# define IPADDR1 168# define IPADDR2 1# define IPADDR3 234
 
#define GWADDR0 192 # define GWADDR1 168 # define GWADDR2 1 # define GWADDR3 1 
 
#define MSKADDR0 255# define MSKADDR1 255# define MSKADDR2 255# define MSKADDR3 0

The IP-Adress of my PC is 192.168.1.1 with the same subnet adress. Then I connected the Board directly via Ethernet to my PC.

In the console I can read the following:

 
Your Ethernet MAC address is 00:07:ed:0f:b4:14
prepped 1 interface, initializing...
Created "Inet main" task (Prio: 2)
Created "clock tick" task (Prio: 3)
smsc91c111 Auto-negotiation: 100 Mbps, Full Duplex
SMSC ethernet Rev: 0x3392, ram: 8192
IP address of et1 : 0.1.1.234
DHCP timed out, going back to default IP address(es)
Simple Socket Server starting up
 Simple Socket Server listening on port 30
Created "simple socket server" task (Prio: 4)

But now I can't reach the board by a ping (icmp-request) and of course I can't connect via TCP to the board. I wonder why it says that the IP-adress is 0.1.1.234:

1. This is no valid ip-adress, because it includes a zero...

2. It's not the same as I defined it in simple_socket_server.h

Who can help? :)

Regards,

Stefan

P.S.: When I press "run" it takes ~5 minutes until it's really running...

Hello,

Idon't know what to say about your post but I can give you an example of I have done for Stratix 3 development board.

In the file simple_socket_server.h I defined the IP-adress like this:

IP: 137.57.123.58

GW: 137.57.123.200

MASK: 255.255.255.0

in my pc : IP: 137.57.123.55

MASK: 255.255.255.0

GW: 137.57.123.200

under cmd window : ping 137.57.123.58 -t

I hope this will be helpfull.

Best regards,

Jeremy.

hi jjeerreemmyy,

did you connect your board directly to the pc? did you use a special cable?

and what was the console output when you launch the application?

Altera_Forum · ‎10-05-2009

I connected the board with the "usb blaster cable" .

I used the example that uses triple speed ethernet. This example is included with the design kit but it's targetting cyclone ii family. However, you can use it I think.

So, to answer to your second question (if I well understood):

The output of the console was : " Reply from 137.57.123.58: bytes=32 time<1ms TTL=64 " .This show that the connection is established.

Regards,

Jeremy.

And no ethernet cable?

Yes sorry :)

And what was the console output in NIOS II IDE when you launched the application?

________

NIOS II IDE is very strange...

Sometimes there is a build error and sometimes not. Also if I don't change the code.

Anyhow, it's still not working and I don't know why...

Which version of Quartus are you using? In 8.0 there was a bug in the IP4_ADDR macro in network_utilites.c. It should have an extra pair of brackets, and should look like this:

#define IP4_ADDR(ipaddr, a,b,c,d) ipaddr = 
    htonl((((alt_u32)(a & 0xff) << 24) | ((alt_u32)(b & 0xff) << 16) | 
          ((alt_u32)(c & 0xff) << 8) | (alt_u32)(d & 0xff)))

Hey Daixiwen,

Yes, you were right. I added the brackets and then it worked. :)

Hi, I am trying to use simple socket server example on cyclone II dev kit.

It seems to work BUT :

when i send over 41 characters through ethernet (crossed câble) , dev kit goes to malfunction.

I receive random characters and communication hangs.

It is like there is too many characters. Too much work to do for Nios II + IP stack + microC/OS II.

Have you faced to this problem ?

Is there an example of Simple Socket server PLus (that enables FTP, TFTP, ...) for Cyclone II dev kit ?
