Getting started on SOPC

Hi All,

I am just starting to get into NIOS, and I thought that I start by going through the tutorials. I am currently going through the hardware tutorial for a Nios_HW_Tutorial_Stratix_1S10.

When I got to the stage of performing a "System Generation" in SOPC, it failes. The display output is not too helpful as the first error that it reported is a "not found", but does not indicate what it didn't find.

A copy of the output is shown below.

I was wondering if anyone has come across the same problem. I read through some of the documentation and I though having more than one installation of cygwin may cause this problem, I was not able to prove this.

Any ideas?

thanks,

Tehn Yit Chin

    Try a hello world program for the compile. Looks like just a C syntax error (can't tell the error really though). Try the line number it gives you to debug the code.

    Thanks for the advise., but I have resolved the problem. I discovered that the PC I was using for the tutorial is really messed up with about 3 version of cygwin installed on it. I suspect that this is what is confusing the SOPC.

    To cut a long story short, C: drive was wiped cleaned and everything was installed cleanly. The compilation was OK from then onwards.

    Thanks,

    hehe ya, I've had who knows how many versions installed over time on this computer, now I get blasted with windows error every time I open the Cygwin shell or compile with the NIOS II IDE (the file not recognized, do you want to replace it from you're window CD error message)

    That makes me wonder what Cygwin actually does to you're computer (I have no idea, not a linux guy)
