Thanks, DushyantIn my Aboriginal Linux project (http://landley.net/aboriginal) I have a config that builds a ppc440 cross compiler and builds a root filesystem and kernel with it, but the kernel .config is bog standard 32 bit PPC (mac99 board I think). It boots and runs, gives you a shell prompt, but occasionally misbehaves you try to do anything fancy with it. Yes, qemu supports ppc440(bamboo).Last I checked, the bamboo board was implemented for KVM not QEMU, and QEMU didn't have a ppc440 processor emulation. But that was over a year ago, things could easily have changed... $ qemu-system-ppcemb -M ? Supported machines are: mpc8544ds mpc8544ds bamboo bamboo ref405ep ref405ep taihu taihu mac99 Mac99 based PowerMAC g3beige Heathrow based PowerMAC (default) prep PowerPC PREP platform I am using arch/powerpc/configs/44x/bamboo_defconfig.What kernel .config are you using for the bamboo kernel? Rob Thanks, Dushyant |
