tse_mac with dp83848 phy in MII interface

[Altera_Forum]

Hi 

 I am trying to make a design with a triple speed ethernet MAC from Altera work. I am using a National DP83848 PHY and the small 10/100 version of the MAC.Currently I have this problem:  when I run the nichestack init, I get this output:   InterNiche Portable TCP/IP, v3.1  Copyright 1996-2008 by InterNiche Technologies. All rights reserved.  prep_tse_mac 0 prepped 1 interface, initializing... [tse_mac_init] INFO : TSE MAC 0 found at address 0x00000400 INFO : PHY National DP83848C found at PHY address 0x1f of MAC Group[0] INFO : PHY[0.0] - Automatically mapped to tse_mac_device[0] INFO : PHY[0.0] - Restart Auto-Negotiation, checking PHY link... INFO : PHY[0.0] - Auto-Negotiation PASSED INFO : PHY[0.0] - Restart Auto-Negotiation, checking PHY link... INFO : PHY[0.0] - Auto-Negotiation PASSED INFO : PHY[0.0] - Checking link... INFO : PHY[0.0] - Link established INFO : PHY[0.0] - Speed = 100, Duplex = Half OK, x=0, CMD_CONFIG=0x01000000 MAC post-initialization: CMD_CONFIG=0x05000603 [tse_sgdma_read_init] RX descriptor chain desc (1 depth) created IP address of et1 : 0.0.0.0 Created "Inet main" task (Prio: 2) Created "clock tick" task (Prio: 3) DHCP timed out, going back to default IP address(es) Simple Socket Server starting up   at the same time DP83848 is very hot? Could someone give me the golden tip to get this running?I would really appreciate your reply!

Actually you're printout is exactly as it should be. I don't see anything amiss at all.

Other than your DHCP timeout. Is it supposed to be getting the IP address via DHCP (you have it connected to a DHCP server)? 

 You might consider changing the static IP address from 0.0.0.0 to something useful.  Jake

hi jakobjones 

i have connected to a dhcp server and once i change a useful ip(e.g 192.168.1.102) i get the following out: InterNiche Portable TCP/IP, v3.1  Copyright 1996-2008 by InterNiche Technologies.

this " IP address of et1 : 0.1.1.102" why is it different from what i defined?

[Altera_Forum]

There is a bug in the macro that converts the defines to an IP address. I think some parenthesis are missing. There is a thread about that in the Nios forum.

hi Daixiwen 

thank you very much.i almost spent two weeks to solve this problem.i expect my system can receive and transmit data packets.what should i do next?thanks again!

hi 

yesterday i can ping my board(cyclone III EP3C10+SRAM+FLASH+PHY),but now it always show "request timed out ".

[Altera_Forum]

You should install something like Wireshark on your PC to see what is sent and received on the Ethernet link. Then use some SignalTap probes on the MII interface to see if the packets are correctly sent/received.

Hi Daixiwen 

I still can not ping my board(which I designed on my own). Pin assignment is also distrubution of my own.I'm a student and this is my first time use FPGA.can you help me check it ?please

[Altera_Forum]

Did you try Wireshark and SignalTap as I suggested in my last message?

[Altera_Forum]

I am working on a similar system. I have gone over the user manuals and such but it is not clear how to set up the software to run on the nios and use the TSE mac. All I want to be able to do is send out packets over the ethernet. How do you "run the interniche init".

[Altera_Forum]

The easiest way to start is to use the Simple Sockets Server design example in the IDE and modify it to suit your needs. Just use the standard sockets API to send/receive packets.

"DHCP timed out, going back to default IP address(es)" 

is does not matter,you could not be troubled by this,you only to set the MAC address by yourself,if the PC can ping,there is nothing to bother~then you can use hyperterninal of pc to view application layer transmition.
