Macronix NOR Flash not worked on power up with Cyclone 5

I am using the Macronix NOR Flash(MX25L12872FM2I-10G) with Cyclone 5 just to store some configurations required during power on the system. Previously I am using Micron NOR flash. The reason behind not functioning of Macronix NOR Flash with Cyclone 5 was dummy cycle.

But my questions are below:

1. How these both Micron and Macronix NOR flash working with Cyclone 4?

2. How Micron NOR Flash works with 12 dummy cycles with cyclone 5 as the Device selected in Quartus programmer is "EPCQ"?

3. Why Micron NOR Flash works with 8 Dummy Cycles with cyclone 5 as the device selected in Quartus programmer is "EPCS"?

All the failures happen on powering up the system.

All the JIC files (With Device selection "EPCS" / "EPCQ") are programmed successfully and even the read back (verify) test was successfully passed in the Quartus Programmer tool.
