The ARM full system files are going through a bit of a transition on the website at the moment. You can compile boot.arm from the system/arm directory in the gem5 repository and a more extensible set of disk images, kernels, etc should be ready by the end of the week.

I made a new, larger .img disc image and copied over the base system files from the included ael-arm.ext2. I also modified the paths in configs/common/Benchmarks.py to point to the correct .img upon bootup. However, when I run it, I get the following error: command line: ./build/ARM_FS/gem5.opt configs/example/fs.py Global frequency set at 1000000000000 ticks per second info: kernel located at: /dist/m5/system/binaries/vmlinux.arm fatal: Could not read bootloader: /dist/m5/system/binaries/boot.arm @ cycle 0 [ArmSystem:build/ARM_FS/arch/arm/system.cc, line 66] Memory Usage: 408828 KBytes I didn't make any changes to the binaries from the included example. I also do not see a boot.arm file in the binaries folder, but there isn't one included in the original example on the website and that one booted fine. Is there something that I am missing?

If you use a .ext2 file gem5 expects it to just be a ext2 disk image without the partition table. You'll want the prior not the latter and to name it with a .img extension. That will use a a compact flash controller in the system instead of mapping the disk into flat memory.

I created a larger disk image using the "gem5img.py" script and mounted both the new larger disc image and the original disc image to my host system.
