So I tried what you said. For the disk: I compiled Android from source, dropped all the relevant files from different Android file systems into one big ext2 file system mounted at '/'. As for the kernel: I followed the instructions here to compile the kernel : http://www.linux-arm.org/LinuxKernel/LinuxAndroidPlatform as you told me. I notice I need to rename the disk image to ael-arm.ext2 and the kernel to vmlinux.arm for fs.py to load the kernel and disk image correctly. After doing so, and changing the M5_PATH to point to the appropriate files, I am still unable to boot it in Full System. Here is what happens: 1. I first run ARM_FS using the kernel I built from http://www.linux-arm.org/LinuxKernel/LinuxAndroidPlatform ( specifically I use the uImage file that the build generates) . The file system is generated by compiling Android from source and aggregating files. It says vmlinux.arm could not be loaded. I am not sure, but probably the kernel image is not expected to be a uImage ( which is created from the Linux kernel build) but rather something else ? Alternatively, is a separate bootloader file required ? 2. So I tried copying the ARM_FS full system files from http://www.m5sim.org/dist/current/arm/arm-system-2011-08.tar.bz2 and tried running that ( after renaming the kernel file in 'binaries' to vmlinux.arm and the disk image in 'disks' to ael-arm.ext2). It now fails with : fatal: system.membus has two ports with same range: system.bridge-portB system.diskmem-port0 @ cycle 0 [recvStatusChange:build/ARM_FS/mem/bus.cc, line 551] Memory Usage: 7391584 KBytes 3. I also tried the Android file system I created with the kernel taken from the gem5 site. That fails as well. Any help on this would be great.
