how to program the .elf file into the flash

use jtag to download the .elf into the ssram and run, use the command:

nios2-download -g *.elf , succeed.

but if i want to download the .elf file into the flash and run , use this command , system generates message:

downloaded 62kb in 1.4s(44.2kb/s)

verifying 0c000000 (0%)

verify failed between address 0xc000000 and 0x c00f54b

leaving target processor paused.

i have to use nios2 IDE. import the project, tools/flash programming/. this is too troublesome.

who can tell me how to download the .elf file into the flash using command line method. thanks.

    I don't have the DE2. But as far as I know, you need to use the "flash programmer" to download elf or sof files to flash via JTAG.

    In your sopc system, a cfi flash controller is needed as well.
