Hi,
I can boot the full system ARM+RUBY with following commands
./build/ARM/gem5.fast configs/example/fs.py
--machine-type=VExpress_GEM5_V1 --kernel
/home/khilji/gem5/m5/system/binaries/vmlinux.aarch32.ll_20131205.0-gem5
--disk-image /home/khilji/gem5/m5/system/disks/linux-aarch32-ael.img
--dtb-filename
/home/khilji/gem5/m5/system/dtb/vexpress.aarch32.ll_20131205.0-gem5.4cpu.dtb
--num-cpus=4 --cpu-type=timing --mem-size=512MB --ruby --num-dirs=2
--garnet-network flexible --topology Mesh --mesh-rows 2 --numa-high-bit=28
and the linux terminal shows following

And this message appears.
fatal: Unable to find destination for addr 0x1c020000 on system.iobus
Actually, this is the unused space in realview.py memory map for
VExpress_GEM5_V1. How can I connect this unused space some where on iobus.
Any suggestions please
best regards,
