Cyclon IV active serial configuration failed

Hi

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.

Do you have an idea what the problem could be?
