Please don't top post.

Sorry!

AFAIK the model won't open the xterm until something reads or writes the
related serial port. So if you haven't configured your console correctly
then they may never show up.

What is your hypervisor command line (in the DTS)?

You could also try using CONFIG_EARLY_PRINTK=fastmodel when building
Xen.

Hi Ian,

It still doesn't appear. I download xen-4.4 (also try xen-4.3.0) and compile it with this script:

xiaoguang@dophine:~/works/arm/xen/xen-4.3.0$ cat compile-xen.sh

CONFIG_EARLY_PRINTK=fastmodel 

CONFIG_DTB_FILE=/home/xiaoguang/works/arm/xen/vexpress-v2p-ca15-tc1.dtb 

make -C xen XEN_TARGET_ARCH=arm32 CROSS_COMPILE=/usr/bin/arm-linux-gnueabi-

And I run it with this command:

xiaoguang@dophine:~/works/arm/xen$ cat start-xen.sh 

model_shell ~/ARM/FastModelsPortfolio_8.2/examples/FVP_VE/Build_Cortex-A15x1/Linux64-Release-GCC-4.4/cadi_system_Linux64-Release-GCC-4.4.so xen-4.3.0/xen/xen -C motherboard.flashloader0.fname=zImage

Is there anything else I have to do to configure the console? I don't know what this means on wiki:

console=dtuart dtuart=myserial 

Thanks!

Xiaoguang
