I am using the following command parameters to run 4 core configuration:

command line: build/ARM/gem5.opt configs/example/fs.py
*--kernel*=vmlinux.aarch32.ll_20131205.0-gem5
*--dtb-filename*=vexpress.aarch32.ll_20131205.0-gem5.1cpu.dtb
*--disk-image*=ARMv7a-ICS-Android-video.SMP.nolock.img
*--script*=./configs/boot/hack_back_ckpt.rcS --frame-capture --caches *-n 4*
--cpu-type=arm_detailed --l1d_size=32kB --l2_assoc=16 --l2_size=2MB
--mem-size=2GB --*machine-type*=VExpress_EMM

But the above configuration boots 1 core. So I changed the dtb file to
follows:

--dtb-filename=vexpress.aarch32.ll_20131205.0-gem5.4cpu.dtb

But now I am getting following errors:

191396615500: system.cpu1.break_event: break event panic triggered
191396626000: system.cpu1.break_event: break event panic triggered
191396626500: system.cpu1.break_event: break event panic triggered
191396627000: system.cpu1.break_event: break event panic triggered
191396627500: system.cpu1.break_event: break event panic triggered

and the system is struck.

Can you please guide that what configuration to use for getting atleast 3
core up running.
