command line .hexout compression

Hi, 

 

I'm having a hard time generating a compressed .hexout file out of an .sof. I've looked into the shell scripting manual of the quartus_cpf utility, did everything "by the book" - to my understanding - and I still get the full size .hexout file. Could you help me see what I do wrong? 

 

This is what I do: 

 

quartus_cpf -c source.sof target.hexout --option=optionfile  

 

where optionfile is a text file containing the following line: 

compression=on  

 

The command gets accepted but the resulting size of the .hexout is unchanged. 

 

Performing the conversion in Quartus GUI with "compressed" option results in a .hexout file of about 40% the size of the one I get in command line. 

 

What do I do wrong? 

 

Thanks!

Got it... the correct option is  

 

bitstream_compression=on.
