No CFI table found

On board I have changed device from EP2C5 to EP2C8

2 flash address pins were reassigned as devices are not pin compatible.

Because of these I have newly carried out Flash Flow in Board descriptor defining the Flash interface for the board.

When i try to program the flash it gives message as

No CFI table found at address 0x00000000

Is this related to target board change or reason for this is something else.

Earlier when the device was EP2C5 Flash was getting programmed.

Please advise.

Thanks and Regards
