Thank you for you answer.
I wanted to emulate under cortex-M3 because I need to exéutute an
executable who will install a kernel but only runs under cortex-M3, for
then realized fuzzing on this kernel.
But, I will try with freeRTOS.

Title:
qemu-system-arm segmentation fault with cpu cortex-m*
Status in QEMU:
New
Bug description:
I try to run an emulation with qemu-system-arm under a cpu cortex-m3
but any execution under the processor result by a segmentation fault.
My command is : qemu-system-arm -m 256 -M versatilepb -cpu cortex-m3
-kernel ~/qemu/wheezy/vmlinuz-3.2.0-4-versatile -initrd
~/qemu/wheezy/initrd.img-3.2.0-4-versatile -hda ~/qemu/wheezy/hda.img
-append 'root=/dev/sda1'
If a lauch the emulation without specifying a cpu equivalent to
cortex-m*, the vm opens up well and works but I absolutely need to run
it under cortex-m3.
Do you have any idea why I have this problem only with this type of processor
?
I also try with other boards different from versatilepb but I have the
same result.
I am under ubuntu 17 64bits during my test.
