</span>I can't help with the other platforms, but for ppce500, make sure you have<br>
CONFIG_PPC_QEMU_E500 enabled in the kernel (and that it's an e500 build, of<br>
course), pass either uImage or vmlinux (not zImage) to -kernel, and specify<br>
the desired cpu type on the QEMU command line (using -cpu) to match the type<br>
of kernel you built. I recommend using e500mc rather than older e500 because<br>
then you get standard floating point which your RFS may depend on.<br>
<br>
Also note that this target will have a serial port for output, not a display,<br>
so configure QEMU appropriately with -serial for how you want to access that.<br>
<br>
If you need more help (especially with other PPC platforms) I suggest the<br>
