NO CFI TABLE FOUND AT ADDRESS 0x00000000

Hi friends,

I am fresher & new to this platform.

In our project, intel 16 Mbyte 128p3oB CFI flash is used.

I configured FPGA, but while downloading the software through NIOS II,I am getting an error which implies,no cfi table found at base address of flash given in SOPC builder'.

In command mode,I tried this command

nios2-flash-programmer --base=0x00000000 --debug

it is showing 0xFF for all locations.(but from user guide,i noticed,it should show CFI/Query table(i saw some query table in data sheet too)).

Previously,in simple designs,i had successfully flashed the program.

if override file should be written,then send me the link,where i can learn about it & how to proceed.

Plz,reply how to resolve this problem?
