Load a .pof in flash using PFL in command line

Hello,

I'd like to program my flash using a .pof file and the parallel flash loader as described here in the application note : http://www.altera.com/literature/an/an478.pdf

This is working, and I'd like to do the same in command line (only the programmer part). By the way, is it possible to see what is executed in quartus gui ?

My tries with quartus_pgm are ok but I don't manage to "attach flash device" with my .pof file ...

I also did some experiments with nios flash programmer but it only accepts sof file and I need to use my .pof file which is encrypted !

Thanks for your help!
