Is there a disassembler for Nios II ELF files?

Hi bkucera,

Use objdump with the -D option.

Take a look at your linker command file, use objdump ... and you might want to

generate a map file as well.

Great, objdump is what I was looking for. Where is my linker command file, and how do I generate a map file? Thanks!

Look in your system library path. E.g. for a debug build:

xxx\Debug\system_description\generated.x

Pass the -Map option to the linker:

$ nios2-elf-ld [OTHER OPTIONS] -Map app.map

Use -Wl,-Map -Wl,app.map for gcc.

Hi,

There is another possibility:

If you are looking for a debugger which directly reads in the ELF file than we can provide a commercial product. This debugger shows besides the opcode and the corresponding disassembled mnemonics also the program flow and cycle count information (per instruction or accumulated over time), and many more features.

You can download this product from www.adveda.com, you can use it for two weeks (license is time limited).

Regards,

Thanks all of you!

It's very kind of you!

I'm from china, and there are few people using NiosII, so I feel alone!:(

Now, I won&#39;t feel alone anymore, because I find my home!:) http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/laugh.gif

Thanks again!
