I have binary that run on Arm Thumb cpu, in embedded devive that not running Linux.
When I tried to run bimwalk or file ,and even open it with Ida ,but they didn't find out that this binary run on Arm processor.
I succeed open it with Ida only when I look on the Cpu board and find out this is Arm.
Is there any tool(without look on Cpu board) that can find out know which processor is for to binary?
Binwalk has this feature but you need to enable it explicitly:
-A, --opcodes
Scan target file(s) for common executable opcode signatures
A project which explicitly tries to determine an architecture of a given binary is cpu_rec from Airbus.
Please note that both solutions can only handle a small set of processors: binwalk has a short list of hardcoded opcode sequences and cpu_rec relies on a small corpus of training files. If your binary uses unusual instructions or processor it might be not recognized.
