-Y option is not available in the original binwalk (https://github.com/ReFirmLabs/binwalk)

What version of binwalk were you using?

OctavioGalland commented 2 years ago

@tosiara it works with Binwalk v2.3.3, it should also work with the version available in the latest Ubuntu's repos.

$ binwalk -Y ./Nebula300+_v12.01.01.37/Nebula300+__V12.01.01.37_en_NEX01.bin  # router firmware used in the presentation

Please let me know which version you are using and what output you are getting.

Got the same issue, found a solution.

From binwalk installation guide:

Binwalk's --disasm option requires the Capstone disassembly framework and its corresponding Python bindings:

$ sudo pip install capstone

-Y is an alias for --disasm. Option description is not shown when requirements are not satisfied.

Great! That is resolved, thanks!
