I'm working on designing a web server application using Nios II Processor for Cyclone 10 GX board. I understand the Quartus pro versions no longer supports Flash Programmer GUI in the Eclipse IDE.
I'm aware of converting my .sof file along with .hex file into a .jic file using Quartus programmer and storing it in the EPCQ flash memory.
But as I was going through Nios II Flash Programmer guide, it explains using sof2flash and elf2flash utilities to generate .flash files from the Command Line.
Could anyone please tell me the difference between these two ways?
elf file is the software project image (Eclipse)
sof file is hardware project image (Quartus)
Thus, sof2flash and elf2flash is converting software image and hardware image to an S-record file.
