Hello,

I am trying to build the full system simulation on ARM using
*arm-ubuntu-natty-headless.img *

on 14.04.1-Ubuntu


followed the instructions on this video :


https://www.youtube.com/watch?v=gd_DtxQD5kc&t=208s


I have set the path variable.


ga87fev@TUEISEC-Stu04:~/gem5$ echo *$M5_PATH*

/home/ga87fev/gem5/full_system_images/


and have these files in place at binaries and disks :


ga87fev@TUEISEC-Stu04:~/gem5/full_system_images$ ls

*binaries*  *disks*

ga87fev@TUEISEC-Stu04:~/gem5/full_system_images$ cd binaries/

ga87fev@TUEISEC-Stu04:~/gem5/full_system_images/binaries$ ls

*boot.arm*        *configs*
vexpress.aarch32.ll_20131205.0-gem5.4cpu.dtb  vmlinux.aarch64.20140821

boot_emm.arm    vexpress.aarch32.ll_20131205.0-gem5.1cpu.dtb
vexpress.aarch64.20140821.dtb                 *vmlinux.arm.smp.fb.2.6.38.8*

boot_emm.arm64  vexpress.aarch32.ll_20131205.0-gem5.2cpu.dtb
vmlinux.aarch32.ll_20131205.0-gem5

ga87fev@TUEISEC-Stu04:~/gem5/full_system_images/binaries$ cd ../disks/

ga87fev@TUEISEC-Stu04:~/gem5/full_system_images/disks$ ls

*arm-ubuntu-natty-headless.img*  *linux-arm-ael.img*

ga87fev@TUEISEC-Stu04:~/gem5/full_system_images/disks$


I am trying to run the following command and it fails.


ga87fev@TUEISEC-Stu04:~/gem5$ .*/build/ARM/gem5.opt configs/example/fs.py
--disk-image=/home/ga87fev/gem5/full_system_images/disks/arm-ubuntu-natty-headless.img*

*Could you please help me solve this error?*


Once this works, I want to try the inbuilt benchmarks.


Thank you for your help.
