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. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1728448 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. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1728448/+subscriptions
