Hi,what does the err info mean?

Hi all,

When I compile a project in NiosII IDE(shipped with QuartusII 4.2),there too often comes

out a err message:

Error hello_world *** [E:/files/My_module_try_nios/Nios_sim/dummy_file] Error 2

And I did find out this so-called "dummy_file" and it's just an empty file without anything.

So could any one tell me why this err comes out and what leads to this err?

Thanks so much!

Regards,

Don

    I don't know why? Maybe it is like the "dummyfile" in linux.

    You can try:

    1. create a dummyfile manually

    2. re-generate in SOPC with Enable "simulation with modelsim"

    Hi

    Its just something wrong in your code. NIOS Editor aka Eclipse tends to do that sometimes. Try starting from a helloworld project and copying your code instead of a blacnk project.

    just my two cents

    http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif oops, you did use hello_world.

    could you please check the following?

    (1) did you save the file after modification, The IDE does not auto-save neither does it notify the user

    (2) if it still does`nt work , just restart IDE and it works sometimes for me

    regards

    as for what problem you posted above, i have meeted it also.in my opinion,it had to do with the version of the software.because afger i tried to update my quartus to version 5.0,meanwhile,i work it smoothly without the problem you had meeted.

    good luck
