5CEFA5U19I7 + MX25L25635FZ2I-10G + Quartus 13.1，The Flash runs with some errors

Hello！ everyone，I had a problem with Flash recently

I used to use Cyclone V (5CEFA7F27I7N) with Quartus 13.1, and the flash I used is MX25L25635EZNI-12G, I add

[EPCS-C22019] # EPCQ256N (Eon-lead-free)

sector_size = 65536

sector_count = 512

to the nios2-flash-override.txt according to the online tutorial，

and then I use the NIOS flash programmer to Program my code to FLASH，it runs correctly after restart.

However, this time I changed the MX25L25635EZNI-12G to the MX25L25635FZ2I-10G (the Identifier of the two flash is all EPCS-C22019,so I don't need to change the nios2-flash-override.txt ),the FPGA I used is Cyclone V (5CEFA5U19I7N) all the rest of the configuration is the same, It didn't work! after I restart it had no code to run! I don't know why,

it's some problem with Flash or Quartus version?

do someone have some suggestion or have the same problem? I need your help! thank you!

the configuration of Quartus 13.1

    Does the second (new) device program successfully? - It should be obvious if it doesn't.

    Are you absolutely convinced you're programming the new part with the same configuration file? Sorry this sounds daft but it's happened (several times) on the forum before...

    Cheers,
