Hi all,
I have configured and built qemu with device tree support.
qemu-version: 0.13.50
I have built kernel image (uImage) for bamboo using powerpc-440 toolchain.
kernel-version: 2.6.37-rc6+
When I try to run this command,
# qemu-system-ppcemb -nographic -m 128 -M bamboo -kernel uImage -append ""
I get the following output and qemu just hangs there:
Trying to read privileged spr 947 3b3 at 00001028
Trying to read invalid spr 62 03e at 00000778
Has anyone tried to emulate bamboo with qemu before ?
Thanks,

In 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.
I am also using
<http://www.landley.net/aboriginal/downloads/binaries/cross-compiler-powerpc-440fp.tar.bz2>"cross-compiler-powerpc-440fp"
from the aboriginal project
(http://www.landley.net/aboriginal/downloads/binaries/) to build the
kernel image :).
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...
Yes, qemu supports ppc440(bamboo).
$ 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
What kernel .config are you using for the bamboo kernel?
Rob
I am using arch/powerpc/configs/44x/bamboo_defconfig.
Thanks,
