Hi,

yes you can do this. First what kind of flash you are using? if I have the sof and the Hex (code) I can create a JIC or POF file to program the flash. Then you can update the code only (HEX). BTW you must notice that changing in Qsys design requires re-compiling the design and updating the Code based on the new .sopcinfo file. If you just need to change the software (HEX) it is OK no nee to recompile the design on Quartus.

Regards,

    Hi,

    Thanks for the fast answer,

    I know when I change the qsys file I need to recompile, But in my case I change only the HEX (C Source in NIOS).

    I have this flash memory: W25Q32JVSSI.

    Please guide me how to load the changing of the hex file only.

    Best Regards,
