I try to disassemb some code for an Arduino DUE.
I moved the file avr-objdump.exe and the [filename].ino.elf to the same dir, and start the CMD.
After the command ".\avr-objdump -S [filename].ino.elf > disasm.txt" the program answer:
can't disassemble for architecture UNKNOWN!
I can't find any option to tell the disassembler to use a SAM3x8.
Can the disassembler only disassemble AVR?
KG_DK:
Can the disassembler only disassemble AVR?
That's what the name implies. Note that the DUE uses an ARM chip. Enable verbose output during compilation to see where the compiler etc. live, there's probably a disassembler as well, if not you can download one if you know the compiler.

Thank you, i will try to do that.
Can anyone tell me the name for the compiler in Arduino?
And for the assembler, if it has its own name?
The first lines in the dump is this, and I can't see anything telling me the name!

It's arm-none-eabi-gcc.
A quick Google search reveals that you can use arm-none-eabi-objdump.exe.

Thank you, I will try it now.
And it work excellent. 
Thanks you wery much.
