there are several 'small print' need to know things about the platform
flash, check all errata and answer records. you are enabling compress in
bitgen options right? there are problems with the compress done by the
platform flash, check the platform flash /impact user guide.

sorry I dont know the direct answer. I do know there are issues, also some
issues are related to some date codes only so check all relevant materials,
if nothing helps open webcase, ie the usual path.well as WebCase support is
now done from China I doubt if that brings anything.

For me the platform flash are on DO NOT USE list. I just have worked with
them so I know something about them - like details of the programming what
is still not published (and will never be) by Xilinx. Had to reverse the
algorithm from SVF files
