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,
Dushyant
    

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.

  

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...
  

What kernel .config are you using for the bamboo kernel?
