Hi Scott,

A strange problem, so annoyed.

In Nios SDK Shell, I type command you say under my u-boot directory.

$elf2flash --base=0x0 --end=0x1fffff --input=u-boot --output=u-boot.flash --flash=U20

Respond : elf2flash: No reset address provided on the command line, and none found in the ELF file

Then, I add.

$elf2flash --base=0x0 --end=0x1fffff --input=u-boot --output=u-boot.flash --flash=U20 --reset=0x0

Respond: elf2flash: Boot copier file name required, error generating Flash file, exiting

I redo, add

$elf2flash --base=0x0 --end=0x1fffff --input=u-boot --output=u-boot.flash --flash=U20 --reset=0x0 --boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_cfi.srec

Respond: elf2flash: read error: File not found: c:/altera/kits/nios2/component/altera_nios2/boot_loader_cfi.srec

elf2flash: Error reading boot copier

Does elf2flash need all parameters?

My path C:\altera\kits\nios2\components\altera_nios2\boot_loader_cfi.srec is right, but elf2flash can not find the file. Why?
