Respected, Steve, I am using the simple commands described on the gem5 website with the linux kernel also downloaded from gem5 website. I am doing it for ARM. build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/junaid/ gem5/disks/arm-ubuntu-natty-headless.img Is there any detailed CPU model in this? Ruslan, Are you also building the system for ARM?
