eCos and Instruction Set Simulator

Hi,

I also need to test eCos on Nios and have no hardware. So I need to run it as Simulation.

Find below what I did so far.

I followed the tutorial which comes with eCOS installation and

Step 1

======

I created the eCos library and then I built it successfully

Step 2

======

I built the application from SDK shell with

make INSTALL_DIR=/cygdrive/e/altera/eCOS/test00_install

It produces some warning related to some command line options valid for C++ only, not for C.

Anyway it seems to work.

Step 3

======

Run IDE

File-> New->Project

Select: Alera NiosII->Advanced C/C++ Project, => Next

Name= ecos_hello

unselect 'UseDefaultLocation' checkbox

Location= E:\altera\eCOS => Next

select 'Make Builder' tab

unselect 'use default',

Build command= make INSTALL_DIR=/cygdrive/e/altera/eCOS/test00_install

=> Finish

I select 'ecos_hello' project

Project->Build Project

Console msg:

"make INSTALL_DIR=/cygdrive/e/altera/eCOS/prova00_install all

make: *** No rule to make target `all'. Stop."

Or should I skip the build process?

Thanx.

i investigate if ecos on nios could answer my needs.

however, i do my tests at home, where i haven&#39;t any hardware.

is it possible to make a small application and to run it on the instruction set simulator ?

when i try "run as...", i get :

| an internal error occurred during: "launching".

| java.lang.nullpointerexception

| ...

| org.eclipse.core.internal.jobs.worker.run(worker.java:66)

thanks,

Sorry, I forgot to say that I&#39;m using IDE version 5.1.

Do the examples provided with the package run as simulation (inside IDE, when there&#39;s no hardware)??????????????

Thanx.

I&#39;m afraid you&#39;re skiing off piste, the eCos port was only ever run and tested on real hardware. I&#39;m afraid you&#39;re the first to try it in the simulator, so I won&#39;t at all be surprised if you run into problems. I suspect by far the path of least resistance would be to get a board.
