quartus_map.exe Exception: Access Violation

Moin,

OK, Ryscs shot in the dark hit the target - in other words: When i delete the db/ directory, im able to compile my design again. It's also running on Hardware, (=i can download & run Software on the NIOS). If i open the SOPC again and rebuild it, even with no changes i'll get the same Access Violation again during the compile of the whole system. If i delete db/ before compiling, everything will work fine again.

This behaviour is just on one particular project, on others in QII6.1 everything is ok (so far). I assume, something in an input file of SOPC got broken, which causes something in the db/- director to be lethal for quartus_map.exe if SOPC was running before.

I'm pretty lucky, that i'm currently doing just the first steps and so the time i waste with this kind of effects is just within days, not months :rolleyes: and also switching the QII-Version is still possible. But i want to keep this time as short as possible and start concentrating of the specific problems of my design - there'll be more than enough of it, but a stable Designsoftware is mandatory first.

In the past, i've never dared to migrate a project from one Version of quartus to another - i've yet faced enough problems without doing so :) - so i also won't do in the future.

I'll try to install 7.1SP1 - it'll take some days because of an evil combination between the huge files (no standalone SP1 available for Web Edition) to download, our firewall at work (eating up large downloads), slow download at home and a to small USB-Stick for passing the file(s) unsplit. :)

But i've no good feeling at all with this, when i have a look e.g. at here:

In my design there will be a few (2-4) self-made SOPC components, so i'll have to expect similar effects :( At least those components do not yet exist outside of my brain, so i might still hope things won't get to ugly because components are done from scratch in the same QII Version.

I've already faced the same problem (...Pausing target processor: not responding....) with 7.1 as rjackal does with 7.1SP1, which caused me to step back to 6.1. and in opposite to other people, i'm not a huge supporter of java language - there are just to many examples, where introducing java resulted in huge, slow and bad behaving software.

Cheers
