i've tried elf2flash, which does let me attach the bootloader, but then when I try the following command I get an error:
nios2-elf-objcopy --input-target srec --output-target ihex sw.flash sw.hex
error ":Interleave must be positive"

You've put the options here with two dashes before, but I bet you've only got one on your command line. That is, your command has the option -input-target rather than the option --input-target, so the nios2-elf-objcopy command thinks it's the interleave option. There's the same error in the official Altera knowledge base article.
