Altera TSE driver and example program for lwIP (1.3.2)

Dear billa:

My board can ping it,But I meet another qusetion,I want to use the udp protocol to send and receive message!Unfortunately I can't send.I want to use the board acts as client and send the message to computer.maybe my code lose someting important,could you help me check it?

waiting for your reply,thank you very much!

here is my code:

/*

* Simple lwIP 1.3.1 example program.

*

* Expects no Operating System (NO_SYS=1)

*

* lwIP initialization and optional DHCP and WEB server support can be

* enabled by setting# defines described below.

*

* You must plug in your board's MAC address below before compiling!

*

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

I cannot unstand why? this example use UC/OS???

Billa I meet this problem,can anyone help me?thanks

waiting for your reply,thank you!

HI

I met this problem,how can i solved?can you give me some advices?which path may i chose?

Dear Daixiwen

how does this error happen?can you give some advices?

Hi,billa

cannot insert breakpoint 0 is my problem!

I use quartus 9.0 and nios 9.0&#65292;and I use this example to build the project http://www.alteraforum.com/forum/showthread.php?t=23787&page=3

now I can ping the board,but I can not use UDP to send the packget&#65292;so I try to debug step by step,and set the breakpoint at function udpsend().(see in picture1)As I seeing the flow,when it return,until to the function udp_sendto_if() ,pointout wrong(see in picture 2),this problem makes me truble,a week,could you give me some advices.

best wishes to you,waiting for your reply.thank you!

Please stop sending the same question multiple times. It won't get you more answers.

I rarely use the debugger so I can't be of much help here. For starters is 0xe11fc a valid program address, i.e. an address in your main RAM region?

IF the address is complete bogus, it could indicate a memory corruption or a head/stack collision.

Hi BillA (and others !),

Really big thanks for your lwip port on altera.

I have succefully implemented the webserver template with lwip on a bemicro SDK from arrow.

I have a question because i don't know how to do it :

actually i have my sgdma Tx and sgdma Rx mapped on a DDR ,

the same DDR where the CPU data an instruction is mapped.

Now imagine i want to use an onchip ram for sgdma tx and sgdmarx instead of DDR.

(but CPU still mapped to DDR)

I tried direclty but this is not working.

if you have any idea .

thanks

I haven't had much luck getting this to port on the BemicroSDK... do you have any pointers on the changes you needed to make to get it to work?

This kind of error typically means the hardware definition is wrong. Something is wrong with memory, clocks, speeds or something. In the past I've told people that have problems with this example to get a standard Altera example running - like Simple Socket Server as-is on your hardware (create app and BSP with that template). If the Simple Socket Server won't run, this lwIP example will never run either. It's pretty hard to test and debug software with unstable hardware.

If an Arrow FAE will comp me a BemicroSDK kit or if you want to send me one, I'll get lwIP running on it. I don't use Cyclone IV at work so have no access to this kit (nor the need to ask the boss to get me one). You will have to get lwIP hooked into the TSE driver used on the IV and configure lwIP for accessing the PHY. Not trivial if you've not done an lwIP port, and it even might not be so trivial if you have. :)
