I recommend using e500mc rather than older e500 because then you get standard floating point which your RFS may depend on. Also note that this target will have a serial port for output, not a display, so configure QEMU appropriately with -serial for how you want to access that. If you need more help (especially with other PPC platforms) I suggest the qemu-...@nongnu.org mailing list. -Scott hey i tried what you said, ./ppc-softmmu/qemu-system-ppc -M ppce500 -kernel /home/powerpc/linux-4.4.1/vmlinux -initrd /home/busybox-1.21.0/rootfs.img.gz -append "root=/dev/ram console=ttyAMA0 rdinit=/sbin/init" -serial stdio -cpu e500mc an error displayed Qemu can't load kernel vmlinux other thing i didn't understand how i made sure that CONFIG_PPC_QEMU_E500 enabled in the kernel, what is the default configuration should i use? what's the e500 build ? regards marwa
