I'm getting the identical symptom using the Board Update Portal of a CycloneIV Eval board. I'm entering the following into the NIOS2 Cygwin shell (exactly as instructed by the Altera html served by the Eval board - except reset vector is changed to match my QSYS):

elf2flash --base=0x08000000 --end=0x8ffffff --reset=0x09720000 --input=./myfile.elf --output=myfile_sw.flash --boot/$sopc_kit_nios2/components/altera_nios2/boot_loader_cfi.srec --verbose

There are no errors or warnings, and the .flash file generated is 2 words for a total of 32 bytes. (my input .elf file is 1.2kB )

Does anyone have a solution or idea what's happening? Thanks.
