Dear All:Hi Sachin, Our Quick Start guide has been updated to reflect the addtional arguments required by the poky-qemu script; see the end of: http://www.yoctoproject.org/docs/yocto-quick-start/yocto-project-qs.html and let me know if you are still having issues. I realize you've been having troubles with this and I'd like to help right them. Thanks, Scott -- Scott Garman Embedded Linux Distro Engineer - Yocto Project |

I want to run linux on powerpc on qemu. My host machine is running Fedora13. For that i have downloaded following from yocto project website. Disk Image: yocto-image-minimal-qemuppc-0.9.rootfs.ext3 Kernel Image : zImage-2.6.34-qemuppc-0.9.bin Toolchain: yocto-eglibc-i586-powerpc-toolchain-sdk-0.9.tar.bz2 I have installed toolchain in /opt/poky I have also copied Disk "yocto-image-minimal-qemuppc-0.9.rootfs.ext3" and "Kernel Image : zImage-2.6.34-qemuppc-0.9.bin" in the /opt/poky directory To run qemu i am using following commands [sachin@sachinlinux poky]$ source environment-setup-ppc603e-poky-linux [sachin@sachinlinux poky]$ poky-qemu qemuppc zImage-2.6.34-qemuppc-0.9.bin yocto-image-minimal-qemuppc-0.9.rootfs.ext3 In order for this script to dynamically infer paths to kernels or filesystem images, you either need bitbake in your PATH or to source poky-init-build-env before running this script So i am not able to run poky-qemu command. Please suggest what to do next. Regards Sachin On Thu, Nov 25, 2010 at 2:49 AM, Scott Garman <scott.a.garman@...> wrote:

Zhang, Jessica
Kumar,
I just download the exact same set on my Ubuntu 10.04 (I know
many people are using F13, so I'm sure it's a pretty stable distro for
Yocto to be run on) and everything works, here's my output:
