Dear Fakhrul,

thanks for asking.

We are waiting for the new hardware. However, we are bound to use a 256 Mb ISSI flash with this Cyclone IV due to some other things stored in this flash as well, which require a large capacity flash.

Since the flash is connected to a microcontroller as well, we will try to configure the flash to boot in 3-bytes addressing mode and in that case the Cyclone IV "should be" able to boot from it.

We may need your assistance, therefore, I would like to request you keep this thread open until we reach some conclusion.

Best regards,

Adnan
