I tried to reflash my SPI FLASH memory with the DOS program supplied by XILINX (I don't remember the name of the DOS program) and get an error saying the synchronization word is missing.
How can I include this synchronization word?
No synchronization word in prom file (XILINX)?

In my .mcs file it says in the beginning rows:
:020000040000FA :10000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF00 :10001000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF0 :10002000AA9930A100072000316109EE33213C0F6D
^^^^^^here
But the xspi complains about a missing synchronization word. Isn't the AA99 the synchronization word for a Spartan-3A (on the last pasted row)?
Is it only that xspi is incompatible with recognizing this?
I hade to use the -skip_syncword_check option on xspi so it could download the bitfile to the spi flash. But is is safe?
