help for flash programming error!

Yes, I believe this is your problem:

$QUARTUS_ROOTDIR/bin/jre/bin/java.exe -jar $SOPC_KIT_NIOS2/bin/elf2flash.jar --f

lash=U3 --base=0x00000000 --end=0x80000 --reset=0x0 --input=hello_led_0.elf --ou

This will generate an S0 record in your flash file that specifies something like:

S01A000055333A30313A30303030303030303A3030303830303030A8

Which contains the string " U3:01:00000000:00080000"

So, the programmer wants to program a flash device named U3 that starts

at 0080_0000, but the flash file is for a device named U3 that starts at 0.

You can use the command line to convert your elf to binary, then convert

the binary to flash. When you create the flash file you can lie about the base

address ;-) ... or you can just update your programmer design.
