I am trying to run a simple hello world program in FS mode (ARM ISA) following these steps:
$ wget http://www.m5sim.org/dist/current/arm/aarch-system-2014-10.tar.xz $ tar xf aarch-system-2014-10.tar.xz $ mkdir tmpdir $ sudo mount -o loop,offset=32256 disks/aarch64-ubuntu-trusty-headless.img tmpdir $ cd tmpdir $ cd etc/init $ sudo cp /home/iiitd/Desktop/tty-gem5.conf . $ cd.. $ cd sbin $ sudo cp /home/iiitd/gem5/util/m5/m5 . $ cd .. $ sudo mkdir benchmark $ sudo cp /home/iiitd/Desktop/mine/hello6 benchmark $ cd.. $ sudo umount tmpdir $ echo "export M5_PATH=/home/iiitd/full-system-2014" >> ~/.bashrc $ source ~/.bashrc $ cd gem5 $ build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/iiitd/full-system-2014/disks/aarch64-ubuntu-trusty-headless.img --script=./home/iiitd/a.rcS In another terminal: $ cd gem5/util/term $ ./m5term localhost 3457 ==== m5 slave terminal: Terminal 0 ==== Freeing unused kernel memory: 292K (806aa000 - 806f3000) request_module: runaway loop modprobe binfmt-464c Starting init: /sbin/init exists but couldn't execute it (error -8) Starting init: /etc/init exists but couldn't execute it (error -13) request_module: runaway loop modprobe binfmt-464c Starting init: /bin/sh exists but couldn't execute it (error -8) Kernel panic - not syncing: No working init found.

In the newly downloaded binaries, there is no file called "vmlinux.aarch32.ll_20131205.0-gem5". So, I think I have to change the dtb and kernel names in FSConfig.py into appropriate one. But, I am not sure which dtb and kernel shall we use. I tried with the following with no success: In FSConfig.py: default_dtbs = { "RealViewEB": None, "RealViewPBX": None, "VExpress_EMM": "armv7_gem5_v1_16cpu.20170426.dtb", "VExpress_EMM64": "vexpress-v2p-ca15-tc1-gem5_4cpus.20170426.dtb", } default_kernels = { "RealViewEB": "vmlinux.arm.smp.fb.2.6.38.8", "RealViewPBX": "vmlinux.arm.smp.fb.2.6.38.8", "VExpress_EMM": "vmlinux.vexpress_gem5_v1.20170426", "VExpress_EMM64": "vmlinux.vexpress_gem5_v1_64.20170426", } Thank you. -- Mitali Sinha, PhD Scholar, IIIT Delhi
