I have tested the N25Q512A11G1240E (instead EPCQL-512) with an ARRIA10 configured in AS mode and it works well with the Quartus 15.1 after the .jic file generation.

That's fascinating. Apart from the voltage level difference, there shouldn't be any algorithmic or (conceptual) wiring differences between your design and mine.
Would you mind describing the programming sequence, any non-default device settings you may be using in Quartus, and perhaps a screen grab of the relevant bit of the schematic?
Then maybe we can get to the bottom of this issue and save everyone having to buy over priced EPCQ chips in future.
Thank you
