Dear Gem5 Users,
I am trying to run a 64-bit full system simulation. I execute the
following command :
./build/ARM/gem5.opt -r -d test configs/example/fs.py
--kernel=/PATH/Gem5_Dev/system/binaries/vmlinux.aarch64.20140821
--machine=VExpress_EMM64
--dtb-file=/PATH/Gem5_Dev/system/binaries/vexpress.aarch64.20140821.dtb
--disk-image=linaro-minimal-aarch64.img --script=./script.sh
The contents of the script.sh file are the following:
#!/bin/bash
echo "HELLO WORLD"
ls
m5 exit
The simulator boots up fine, although it takes some reasonable time.
However neither the "echo" command is executed nor the "ls". At the
end the simualtion terminates because of the m5 exit instruction.
The output of the simout is the following:
**** REAL SIMULATION ****
warn: Existing EnergyCtrl, but no enabled DVFSHandler found.
info: Entering event queue @ 0. Starting simulation...

Exiting @ tick 51080808874500 because m5_exit instruction encountered
and the last lines of the system.terminal are:

Any idea why I cant execute any bash command on the simulator. I have
also tried the -b option and the results are the same.
