Hello,

I downloaded latest qemu 0.14.1, it should support realview-pbx-a9 board now
from
below cmd.
$ qemu-system-arm -M ?|grep Cortex-A9
realview-pbx-a9 ARM RealView Platform Baseboard Explore for Cortex-A9

Then I compiled a zImage from latest mainline with use
realview-smp_defconfig as config
file, but unfortunately qemu can't run with the image, I had tried the below
instructions.
1. qemu-system-arm -M realview-pbx-a9 -kernel zImage -initrd initrd.img
-nographic -append "console=ttyAMA0"
2. qemu-system-arm -M realview-pbx-a9 -m 1024M -kernel zImage -nographic
-append "root=/dev/nfs nfsroot=128.225.160.22:/home/work/rootfs rw
console=ttyAMA0 rdinit=/sbin/init" -net nic -net tap,ifname=tap0,script=no
Both instructions can't work, console is hang and no informations is
appeared.
so I am wondering if there are something wrong about the kernel, am I choose
the wrong
config file for realview-pbx-a9 board? Or the native mainline kernel can't
boot on
qemu? Any suggestions? Thanks a lot!

The command I use is:

sudo ./arm-softmmu/qemu-system-arm -M realview-pbx-a9 -m 1024 -kernel
thekernel -serial telnet::4444,server -append "console=earlycon
console=ttyS0 console=ttyAMA0 earlyprintk root=/dev/nfs
nfsroot=10.1.1.1:/armroot rw
ip=10.1.1.2:10.1.1.1:10.1.1.1:255.255.255.0:armqemu nfsrootdebug "
-net nic -net tap,ifname=tap0,script=no,downscript=no

and then telnet to port 4444 to get the console.

(I'm using the linaro qemu tree).

Hi Dave,

Thanks you very much, I will try it :)
