Cyclone3: Flash programmig via JTAG

hi......

if i understand you have a project with soc system running.......

you need to write a .sof and .elf in your cfi_flash .....ok???

to write you need to convert the .sof and .elf in .flash files

at nios2 command shell and in your project directory you need to do

sof2flash --input=(your.sof) --output=(name.flash) --offset=(initial offset) --verbose

your.sof = your project

name.flash = the file generated

initial offset = this is the offset of the flash memmory ...this is a data sheet parameter , i use 0x10000 at my flash

and write your.flash

nios2-flash-programmer --base=(your flash base addres) your.flash --verbose

this write the .flash

to convert the .elf

elf2flash --after=(your.flash) --input=(your.elf) --output=(nios.flash) --boot=bootLoader_cfi.srec

the bootloader file is at your quartus directory -> /altera/11/IP/ALTERA/NIOS2_IP/ALTERA_NIOS2/bootloader_cfi.srec

remember to set up your RESET VECTOR in qsys

write at nios2 command shel is very fast...

cheers
