Is it possible to use qemu with a arm raw image from an embedded device? The device does not use linux. Any links to documentation or general knowledge I can search with appreciated.  

thanks

I just humbly think it is likely possible...after all, Qemu never said
it is just for Linux based platform.....except for user mode
emulation.

Maybe. It depends on the emulated arm platform (qemu supports several of 
them)
load address and other factors.

The code is the documentation. Images are loaded from code in hw/arm_boot.c.
There you can see that qemu supports elf, u-boot and raw images.
Raw images are assumed to be linux images. That's the image loaded by the
"-kernel" parameter.

Depending on the platform, it is also possible to load (boot) roms.

Try parameter "-d in_asm" to see (in file /tmp/qemu) what qemu does
with your raw code.

If you are a programmer and willing to spend (a lot of) time,
the answer to your question is yes.

Cheers,
Stefan Weil
