Sof2flash

I'm trying to convert .sof file in .flash file for EPCS .

I'm using this command:

sof2flash --input=.... --output=.... --offset=0x.... --epcs

I have this question: if I try to change offset I can see the same .flash file as output.

Change just only first row.

I don't understand why. Somebody know how run epcs offset for sof2flash?

BYE

    I'm afraid I don't have an answer for you but you're not the only one. I've just come across exactly the same problem trying to do the same thing! :(

    edit to add -

    I am using the following command: 

    sof2flash --epcs --input=hw.sof --output=hw.flash --offset=0x300000
    and I am using the 7.2 version (fully licensed) of the Quartus tools

    Hi Andrew,

    this question is a little bit strange. i don't understand why there are these problems. I didn't try but there are differences if I use WEB free quartus and NIOS II versions? versions.

    With .flash I have to program epcs but not directly but with EPCS controller so my HOST MICRO, with SPI connection, program EPCS.

    I have to know some important details.

    Bye
