encrypted+compressed .tff with quartus_cpf command line

Context :

Device Stratix3 - EP3SL200F1517 (+encryption)

QuartusII 9.2

Convert Programming File - graphic interface

I need to generate an encryted+compressed .ttf file with the command line "quartus_cpf", instead of using Convert Programming File graphical interface.

I use the following command :

quartus_cpf -c --option=<option file> --key <keyfile>:<keyid1>:<keyid2> <input_sof_file> <output_ttf_file>

with option file contenu : compression=on

The .ttf is generated, functionnal (and well encrypted) :) , but NOT compressed :mad: .

I have tried also this syntax (same resuts) :

quartus_cpf -c --key <keyfile>:<keyid1>:<keyid2> <input_sof_file> <output_ttf_file> -o <option file>

Rq : the option file (.txt file) is recognized (because error if renamed or suppressed), but the contenu seems to be ignored (no error if contenu = "compresion=on" or "toto") :cool: .

The encryption+compression is correctly done using Convert Programming File :) , but we really need to do it in command line...

Thanks for your help.

    I got the same issue here using quartus_cpf 9.0 on Linux RedHat. In my case, I need to generate a *.rbf file but it looks like the same problem with your *.ttf file.

    In the option file, the required setting is :

    BITSTREAM_COMPRESSION=ON

    not COMPRESSION=ON as stated in the documentation.

    Also, I need to append a carriage return character (Linux LF) after the string else the option is simply (and silently) ignored from quartus_cpf.
