Changing memory initialization file without recompiling

[Altera_Forum]

Hi all, 

 I got use SOPC builder and specified a "your_image.hex" as the memory initialization file for the on-chip memory. May I know are there any ways to change the content of the hex file without recompiling the whole project ? Each time I change the content I need to recompile again for it to work. Thank you in advance.

Yes, for the debug you can use the "In system memory editor" described here : http://www.altera.com/literature/hb/qts/qts_qii53012.pdf 

 You select the target memory, then import relevant data file and write it to the embedded RAM and it's done !

Too bad that method doesn't support Nios II on-chip memory and only works on certain megafunctions. Are there other ways?

 quartus_cdb --update_mif <your quartus project name>.qpf quartus_asm <your quartus project name>.qpf  Will generate new programming files with up to date memory initialization files.

this should be the same as going to Processing => Update Memory Initialization File, then running the Assembler (if you're a GUI user).
