[Qemu-ppc] qemu emulates ppc e500 failed‏

[张磊]

Hi,guys,

I'm new to qemu. Now I'm trying to use qemu-system-ppc emulatoring powerpc e500 cpu (like freescale's P1020/P1010). But I faced some strange question.

Firstly I use Yocto making a kernel image and rootfs, and use command "qemu-system-ppc -M ppce500 -kernel uImage -initrd fsl-image-minimal-p1020rdb.ext2.gz -m 256M -nographic" to start linux,this step is ok and I entered linux. But when I want to put some files into qemu, I'm caught in. The net device is missing , so I add paramater "-net nic,model=e1000" (I have checked linux kernel's device driver ,I'm sure "e1000e: Intel(R) PRO/1000 Network Driver" is checked and loaded during startup ) and restart qemu, but the net device is missing too, I typed "ifconfig -a",linux shows below:

Because net is broken, so I tried to create a qcow2 image and start qemu with this image, but I cannot see it in linux on qemu.

Has anyone faced the same/familiar question like me ? Or anyone can help me solve this problem , give me some advices on this .

Thanks very much.
