The .flash file doesn't work in Arria IIGX development Kit

[Altera_Forum]

I have a problem when I used "sof2flash" to convert "factory_recovery\build_factory_source\bts_config.sof" to bts_config.flash.when used Quartus ii and Nios II EDS 9.0SP2,the problem is "The release of Nios II EDS 9.0sp2 tool "sof2flash" does not include support for Arria II GX". When I used QuartusII Nios II EDS 9.1sp1 and sp2 ,the problem is that .flash file's size is not same as your provided file bts_config.flash,and upload this .flash file into development kit,it didn't work. But upload your provided file bts_config.flash,it did work. 

 How should I do? thank you.

when you used sof2flash, did you include the --pfl, --programmingmode, and --optionbit flags?

[Altera_Forum]

no, as the user_guider file says 

sof2flash --offset=0x640000 --input=bts_config.sof --output=bts_config.falsh

not using the mentioned flags will cause the FPGA to fail configuration. take a look at the following solution:

Hi,  

I managed to create .flash file and burn the flash with new image successfully for once. After that, I repeat the process but the FPGA can't run. It is configured successfully though, but all the logic just can't run? Quite confused, same sof file I've used to configure by JTAG, works perfectly.
