Hi Dave,

It looks like I am not in luck, qemu still can't run successfully.
I recompiled the qemu from linaro qemu tree and executed below
instructions in order.

1. open window A, run below cmd.
xjiang@xjiang-desktop:~/work/qemu$ sudo qemu-system-arm -M 
realview-pbx-a9 -m 1024 -kernel zImage-cortex-a9 -serial 
telnet::4444,server -append "console=earlycon console=ttyS0 
console=ttyAMA0 earlyprintk root=/dev/nfs 
nfsroot=10.1.6.6:/home/gjiang/work/ti_sitara_am35xx-standard-glibc_std 
ip=10.1.6.8:10.1.6.6:10.1.6.1:255.255.255.0" -net nic,vlan=0 -net 
tap,vlan=0,ifname=tap0,script=no,downscript=no
QEMU waiting for connection on: telnet:0.0.0.0:4444,server

2. open another window B, telnet to port 4444.
xjiang@xjiang-desktop$ telnet localhost 4444
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

3, Then in window A, "VNC server running on `127.0.0.1:5901'" is appeared,
so I open terminal service client, set the computer name to 127.0.0.1:5901
and selected vnc protocol. But after I clicked connect I can't see any 
infos,
and the window named as "TightVNC: QEMU" is totally black.

Are there something wrong in above instructions? or there are other 
necessary
cmds which I have missed? Thanks in advance!

Xiao
