Sascha, thanks for your reply. As you suggested, I tried gem5 outside of WA. I also prepared a dtb file according to the instructions of this page ( http://www.gem5.org/Android_Marshmallow), which was more clear than the instructions of the Kitkat page.
So, I tried this: hossein@mercury:~/gem5$ build/ARM/gem5.opt configs/example/fs.py \ --kernel=/home/hossein/gem5_images/binaries/vmlinux-android \ --dtb-file=/home/hossein/gem5_images/binaries/vexpress-v2p-ca15-tc1-gem5.dtb \ --disk-image=/home/hossein/gem5_images/disks/android_image.img \ --os-type=android-kitkat But gem5 stops, showing this warning: warn: Kernel panic in simulated kernel The telnet session displays this at the end: VFS: Cannot open root device "sda1" or unknown-block(0,0): error -6 Please append a correct "root=" boot option; here are the available partitions: 0100 4096 ram0 (driver?) 0101 4096 ram1 (driver?) 0102 4096 ram2 (driver?) 0103 4096 ram3 (driver?) 0104 4096 ram4 (driver?) 0105 4096 ram5 (driver?) 0106 4096 ram6 (driver?) 0107 4096 ram7 (driver?) 0108 4096 ram8 (driver?) 0109 4096 ram9 (driver?) 010a 4096 ram10 (driver?) 010b 4096 ram11 (driver?) 010c 4096 ram12 (driver?) 010d 4096 ram13 (driver?) 010e 4096 ram14 (driver?) 010f 4096 ram15 (driver?)
