Using EPCS64 Device with DE0 nano Board

Hi,

I would like to use EPCS64 Device to store FPGA images and NIOS II 
software. For that purpose, in Qsys I add Altera Serial Flash 
Controller.
My design complies with no problem and the image of the FPGA 
configuration is done with success using the programmer tool of Quartus.

Then i used eclipse to develop my software part, But when i use the 
Flash Programmer to create an image of  NIOS II .elf file and then load 
it in the EPCS64, i get error that says that CIF flash is not fond.

I don't know if i used the correct Flash controller.

Could anyone help me about this issue?

Thanks.

Best regards
