Altera TSE driver and example program for lwIP (1.3.2)

Hi!

Enyone can explain me how to execute the points 26 - 39 of the lwIP 1.3.2 Altera TSE driver for lwIP 1.3.2 ReadMe in NiosII 9.1 EDS?

The points are:

26. Select C/C++ Build

27. Select General

28. Add Include Path ${workspace_loc:/altera.components/Nios II Software Packages/altera_iniche/UCOSII/inc}

29. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include}

30. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include/ipv4}

31. Select Configuration Release from the pull-down

32. Select Preprocessor

33. Add Undefined Symbols: LWIP_NOASSERT

34. Add Undefined Symbols: LWIP_ERROR

35. Select General

36. Add Include Path ${workspace_loc:/altera.components/Nios II Software Packages/altera_iniche/UCOSII/inc}

37. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include}

38. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include/ipv4}

39. Select Configuration Debug from the pull-down

Sorry, but I'm new and thanks for help!

Well, you need to do step 25 and you'll see "C/C++ Build" mentioned in step 26.

25. right-click project lwip_nios_ii_example and select properties

Thank you for your reply Bill!

The point 25 is obvious, but after i don't know shere include this paths:

28. Add Include Path ${workspace_loc:/altera.components/Nios II Software Packages/altera_iniche/UCOSII/inc}

29. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include}

30. Add Include Path ${workspace_loc:/lwIP_NIOS_II_Example/lwIP/src/include/ipv4}

Under C/C++ option there are many options, and I think that the correct one is the "Path and Symbols". But there are many tabs, like "Includes", "Library path", "References", ... Which is the correct one?!

And then: where I can find the "Configuration Release" form point 31:

31. Select Configuration Release from the pull-down?

And why the points 27-30 are egual to points 35-38?

Thanks!!! Have a nice day!

Stay on "Tool Settings" tab.

Use General for Nios II Compiler

You'll see Include paths. Use the Add button.

31. Select Configuration Release from the pull-down?

--- Quote End ---

Right above the tabs in this same dialog.

--- Quote End ---

Because you need the include paths for Debug and Release builds.

Thank you - you do the same. :)

Hi guys.

I am still trying to use the example, which has been uploaded by BillA (thank you very much), but i am in trouble. Finally,i know the port number to connect.But, as i understand,this example is low-level example.I mean,that the packets, which i catch, i catch them not on Transport layer(TCP, UDP).I catch them on IP layer or even ARP.

Is it correctly?

Another question. As i understand, i catch the packet in "ethernetif_input" function and i am trying to watch with breakpoints the content of packet, but i do not see nothing.

What am i doing not correctly?

Thanks,Slava.

You're welcome (for the example). You catch the packets you want by specifying the callback. For example, if you call tcp_recv you will be called back with data as it arrives from the connection on the pcb. There is also udp_recv and raw_recv if you want those callbacks. raw has to be enabled with a# define and only it will allow seeing all packets. I've never had reason to use this.

If you put breakpoint on:

ethhdr = p->payload;

and it doesn't stop here, then you are not receiving packets. Run in Debug build and look at the PHY output messages to be sure the PHY initializes OK. If you get through that, I would expect the TSE to be OK but if it won't breakpoint you're not getting any packets. You should see broadcast packets at all times so if you're on a network you should see packets without doing anything. If you are direct to a PC I still think you see a few broadcasts.

Hi!

Many thanks to Bill for useful example and step-by-step pass-throw. I successfully compiled lwIP_NIOS_II_Example in EDS 10.0. A couple of minor issues I faced with:

1) steps 25-40. I tried to set paths and symbols through the GUI, but this didn't work. The workaround was to edit lwIP_NIOS_II_Example/Makefile manually. Also, to get “INFO” output like in Readme.txt ALT_DEBUG must be defined for lwIP_NIOS_II_Example_bsp project.

2) TSE-related components in SOPC must have standard names: 'tse_mac', 'sgdma_tx', 'sgdma_rx' and 'descriptor_memory'. If different names are used the code successfully compiles, but does not function.

Without any modifications the example runs on DBM3C40 devboard (Cyclone III + Marvell 88E1119R PHY) at 100Mbit. It gets address via DHCP and serves nice html page from port 80.

Unfortunately the board hangs at DHCP stage if I plug it into 1000M network. The output is following:

INFO : TSE MAC 0 found at address 0x00002000

INFO : Multi Channel = No

INFO : MDIO Shared = No

INFO : MAC Type = 10/100/1000 Ethernet MAC

INFO : MAC Address = 0x00002000

INFO : MAC Device = tse_mac_device[0]

ERROR : MAC Group[0] - No PHY connected!

ERROR : PHY[0.0] - No PHY connected! Speed = 100, Duplex = Full

Waiting for link...OK

Waiting for DHCP IP address...

I suspect that 1000M operation or autonegotiation must be configured somehow, but I have zero experience in Ethernet development and don't know how to move on. Any help will be appreciated.

Thank you in advance,

Igor

Thank you for your reply.regarding to second question: it works exactly as you have described.

Regarding to the first question:

As i understand, i must to specify the callback function.

At which stage do i must to do it?

In your code(example),as i uns=derstand, i must to insert reading function where i put stars.Is it correct?

// Process lwIP timer dependent code

if(lwipProcessTimerFlag)

lwipProcessTimers();

// Poll lwIP for incoming packets.

ethernetif_input(&alteraTseNetif);

Where i puted the stars, do i must to specify the callback function?

In altera_avalon_tse.h try changing the# define for ALTERA_CHECKLINK_TIMEOUT_THRESHOLD to 5000000

I think perhaps it's timing out before it negotiates? You can also try increasing the other timeouts in this header file (in the same location of the file).

This http code in this example is also an example that shows how to handle the callback from accept and how to set the tcp_recv. It also shows how to process received data. You should model any code that will make a connection and send and receive data like this one does.
