"System ID" problem with "Run as Hardware"

Hi, everyone,

I'm not expert with nios and i beg your help.

Recently I updated my software from quartus 8.1 and Nios IDE 8.1 to Quartus 9.1 and nios EDS 9.1 (sp1)

Recompiled a quartus project and created new projects in EDS (i had problems with 'convert' from IDE to EDS) and everything worked well.

Today I`ve tried new older quartus project to do the same. Everything compiled well, but when I try 'Run as Hardware' or 'Debug as hardware', on 'Tarjet connection' USB-blaster is updated correctly, but System ID and Timestamp indicates N/A. Obviously, trying to donwload fails.

If I check 'Ignore...' download doesn't fail in 'cheching system ID', but do in writing on ram.

It doesn't happen with the first project, so the usb blaster is ok.

When i try with the old project (sof in quartus 8.1) and new nios projects (elf in EDS 9.1) everything is correct. But only recompiling with quartus 9,1 (and also nios within the sopc builder) the error appears. Only my first converted project works well.

¿Any idea or suggestion?

thanks

    Finaly I have a good project. I think it's something with the quartus compilation and my PC: a setting, preference, option or something like that that is uncontrolled.

    To solve the problem I started from the beginning, with the simplest project, adding the componens one by one, compiling, creating a nios program and trying.
