I can't help with the other platforms, but for ppce500, make sure you have CONFIG_PPC_QEMU_E500 enabled in the kernel (and that it's an e500 build, of course), pass either uImage or vmlinux (not zImage) to -kernel, and specify the desired cpu type on the QEMU command line (using -cpu) to match the type of kernel you built. 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 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
