Cyclon IV active serial configuration failed

Hi,

Sorry i am confused with the following explanation. Can you please elaborate on it?

the main problem was the *.jic file generation.

I have excepted that if I select a new configuration device, the default settings would work.

The Default Options/Boot info was set to Little endian instead of Big endian .

But I have still the problem than sometimes the configuration is not working.

Then i delete the db and the incremental_db folder in the project folder, recompile all and regenerate the jic file.

After that it works again.

I guess there is a problem during compilation or in the *.jic file generation.

So you meant that the recompile JIC file is not working fine until you deleted the DB folder and incremental_DB folder in quartus project? This is weird.

Thank You.
