how to port nios2 to stratix dsp s80 board?

Hello niosIIuser:

yes, there aren't any reference designs for S80 used for NiosII. there are only reference designs like DDC,QPSK and so on. In the nios application , I cann't add the cfi to device correctly. it's still the flash problem.My flash support the CFI,16bit device,but I can't open it with the Menory Test program,it's not the Nios II 1.0.1 problem,because the flash can't detect the "QRY" at all. I used

the SignalTapII Logic Analyzer tool to view the signal of address, data,chipselect and so on. In the word model, I see the address[21..0] is:000054h ,the data[15..0] is:0098h when I execute the command:

alt_write_flash_command_16bit_device_16bit_mode(flash->dev.base_addr, 0x55, QUERY_MODE);

I didn't know what's the reason.
