Hi,

well - they should be aware of, as this already has been reported some posts ago in the forum and I also had a support request on this. We could hope, they'll fix it in SP1. As part of my service request, ALTERA gave me a workaround (if you need both, v9.1 and compressed *.pof):

* generate uncompressed bitstream

* start manually File => Convert Programming Files

* Select your's project *.sof and check "Compression" (select *.sof and Properties)

* check the “Disable AS mode CONF_DONE error check” option from the Bitstream Generation Advanced Option Utility (Advanced)

This generates a compressed file, that configures the CycloneII, but for me this would be too much manual work and I think I'd revert to v9.0 SP2 in case I would need a compressed file too (my Hardware EP2C8 and EPCS4 works fine w/o compression)

CU, CS
