Honored Contributorseveral elf files in flash
Hi all... How can I do to write several nios2 applications (elf files) sequentially in flash (without boot_copier) ? Is there a way to set a address where the programmer starts to write in flash...

--- Quote End --- Hello jdhar, thanks for your answer... The offset flag wasn't specified in the elf2flash help..... thanks... But I couldn't generate the flash without boot_loader... I want to write several applications in the flash, each one in determined address. My goal is to create a software that copy a determined application to exception area of a processor (there is 3 nios2) to be run. Therefore the boot_loader isn't necessary, but I don't know how to generate the .flash without it. Follow the command that Im using:
elf2flash --silent --input=myprogram --output=./myprogram.flash --sim_optimize=0 --base=0x00000000 --end=0x007fffff --reset=0x00000000 --boot=C:/altera/kits/nios2_51/components/altera_nios2/boot_loader_cfi.srec --ofset=0x00100000
