Can somebody suggest me any disassembler for Atmel AVR 8-bit microcontrollers? There are opensource projects for this?
Can somebody suggest me any disassembler for Atmel AVR 8-bit microcontrollers? There are opensource projects for this? See screenshots, read the latest customer reviews, and compare ratings for 8051 Disassembler under win10. Download this app from Microsoft Store for Windows 10.

Thanx.

[plug]IDA Pro supports AVR disassembly[/plug]:
As for opensource, AVR GCC package includes a port of objdump, including disassembling functionality.

Digging deeper with the dfx trashy parks. You can also use avr-objdump, a tool part of the avr-gcc toolset ( http://www.nongnu.org/avr-libc/ ). Ex:
Nch express scribe. where
<avr architecture>
is found on http://www.nongnu.org/avr-libc/user-manual/using_tools.htmluser1443332user1443332
Lots of platforms (AVR also) but Microchip (which you didn't need either) is missing.
Big plus is that it is web based.

AVRDisassembler is an open source (MIT) AVR / Arduino disassembler written in .NET Core (which means it can run on Windows, Mac, Linux). Apart from writing the disassembly to stdout, it can also emit a JSON dump (for interopability, analysis purposes).
Disclaimer: I am the author of said library.

Waht you want to disassembly (code or hex file)? If you are coding with Atmel studio it has tool for disassemble, when you coding.
Disassemblers
- Run project (if you haven't debugging tool, use simulator, it has not meaning);
- Then pause;
- Than CTRL + ALT + D will disassemble your project.Also assembly is written in .lss file too, in debug folder of your project.

Exe Disassembler
I'm using avrdisas by Johannes Bauer. It works with dumped flash, rather than the .hex file or ELF.
Compiling the following :
Asce 7 10 pdf download. produces listing:
extracting the flash contents with:
gives:
e001 bb07 9701 f7f1 9ab0 cffc
disassembly:
and this works for me, even if the endian-ness does not match the listing and I would need to resolve 0x17 back to DDRB etc.
