I have found this answer:
"I have had that happen to other customers before. You are using a Micron Config device not an Intel EPCQ512. Your Micron device will work fine and is supported.
It has a NVCR non- volatile configuration register that needs the correct value in it. If you use Quartus( JTAG) it will write to that register and set it in the correct mode, so after you touch it once with the Quartus programmer it should work fine.
If you just program the flash with the bin file without having the register setting the mode correctly chances are you will fail configuration because the default mode of the Micron(3 bit addressing.) is different than the default EPCQ device which is 4 bit addressing
You can have your manufacturing also write to that NCVR register when they write the Bin.
You may want to the read the register of a system that works so you know exactly the value to write to it."
So is it because of config register of Flash IC?
