Is it possible to run a non-linux compiled program on linux?

Question

linux

There is an At91 microcontroller, linux is understood on it (kernel version 2.6, no more details), and a program has been compiled for this microcontroller.
Is it possible to run this program from under linux or somehow in parallel?

Answer 1

At91 microcontroller, linux is understood on it

So you decide what the program is compiled for. Under a different hardware platform or software.
See if QEMU knows the right hardware platform.
