Hi,I need help! 

I am using DE2 board's WM8731 to do a wireless voice transfer system.The sending part sends sound,and the receiving part receives sound. 

I download the .sof to the fpga and run the software in the sdram,and it works well.so I want to program it into cfi flash. 

I programed the software into cfi .I set the cpu reset address to the cfi. 

 

first I programmed .pof into the epcs16,but when I reset it,it doesn't run ; 

then I download the .sof into the fpga, and it runs well. 

what is wrong with it ?Is there anything error? 

Is there anything difference between the .sof and the .pof? 

 

besides,I want to program the hw and sw to cfi flash. 

the cfi flash is 4M,its base address is 0x800000 ,end address is 0xbfffff; 

how should I set the offset of the hw and sw? 

 

I need help! thank you.
