The only example I know about is this one: nios ii udp offload example (http://www.alterawiki.com/wiki/nios_ii_udp_offload_example)

Thank you, Daixiwen.

I'll try to adjust the example to my DVK board and will report the results.

My aim is to use UDP so I believe the example could help me.

Hi,

I looked thru the example, but it is hard to use.

I am new to the SOPC Builder, NIOS II IDE, but have done the first steps using them.

Unfortunately the example prepaired in SOPC Builder is then transformed to be used in the bash shell.

And no source files for SOPC Builder are left. More over the software example is not full I believe.

The essence of the example is clear, but it is not clear what to do -

I use another board and didn't work with the bash shell.

Is it possible to transform somehow the example back to the SOPC Builder environment?

Any advices??

I used this example before under Windows with Quartus 12.1. It's full and nothing is missing there. I think, I just needed to modify required Quartus version in build script "create-this-project.sh" manually. By default it's "EXPECTED_QUARTUS_VERSION="Version 9.0 Build 235". After that magic script creates everything you need to get started.

Hi linas,

Thank you for your test.

My aim is to fulfil my own project not only to examine the example.

So I began to study texts in the IP folder - there the components are written in Verilog.

I found quite everything.

The only issue is I don't know how to use the bash shell.

So I am to become familiar with it.

After changing expected Quartus Version to the needed one you go (in Windows) to Start-> ... -> Altera xxx -> Nios II EDS xxx -> Nios II xxx Command shell. You have thing similar to MS-DOS, with cd <folder_name> and cd .. (go one folder up) navigate to script location. Then type ./create-this-project.sh and it runs. You don't need deep knowledge on that to get started.

Thank you, linas,

The operations you described I'd already tried to fulfil.

My issue essence is that I don't know commands used in the bash shell nor its scripts.

I can guess how to change pins assignment.

But so far I can not check that components and connections of another board will suit for my the Altera Cyclone III Starter Board.

That's why I must study commands and scripts of the bash shell.

Hi,

I compiled the example. My problem was not in the Quartus II version but in correct paths to necessary files assignment.

So though compilation finished I did not get necessary files such as for flash downloading.

It's a preliminary compilation done without any adjustment of the example to suite for my board.

I'll inform you of the results when I fulfil the last operation.

Hi linas,

My compilation of the example using Quartus 9.0 was successful unless only .sof was created due to the Web Edition I guess.

But when I tried to do the same using Quartus 12.1 Build 177 (Web Edition too) there was such a result:

Strings from the bash window:

Info: save_system test_sys_sopc

Error: set_parameter cpu setting_shadowRegisterSetsPresent false: null

set_parameter cpu setting_numShadowRegisterSets 1: null

set_parameter cpu setting_eicPresent false: null

set_parameter cpu setting_autoAssignNumShadowRegisterSets true: null

SOPC Builder was created successfully…

SOPC Builder was NOT generated successfully…

Error in build_and_generate_sopc_system…

Unfortunately I don't know why in the previous version of Quartus this error was not found but in this version was.

I don't know the destination of the parameter 'cpu setting_shadowRegisterSetsPresent'.

After I tried to comment it out the next error was displayed

Error: set_parameter cpu setting_numShadowRegisterSets 1: null ... and so on

I know that the last Quartus versions use the Qsys instead of SOPC Builder. These both systems are similar more over in the Qsys windows one can see many mentions of the SOPC Builder. So hardly it is the reason of the error found.

You wrote your experience in using Quartus 12 was successful.

Could not you advise why my experiment was not.
