hi georgios,

you must use the script.rcs in the statement --bootscript :
--bootscript = / path / script.rcS.

you must generate the script.rsS file for each application, for example for
the blackscholes application of parsec 3.0,

#! / Bin / bash
PARSEC_DIR = "/ home / parsec-3.0"
cd $ PARSEC_DIR
pwd
source ./env.sh
parsecmgmt -a run -p blackscholes -c gcc-hooks -i simsmall -n 2
m5 exit

and also you must integrate the application that you use on the linaro
image.

here is a link to generate your rcS script.

Ali.

I think bootrscript is just an arbitrary script that your must create
yourself to run the benchmark you want, or give you a shell.
It must be being used from the /init of that image to set the m5
readfile path, and then run it.
This kind of thing allows you to checkpoint at the end of boot, but
still run different scripts of your choice after the restore.

which is just a minimal setup that gives a shell, no init magic yet.

Hi,
I am new on gem5 and need your help. I am trying to run the

fs_bigLITTLE.py

(2 big, 2 little cores) but I take an error.
I understand that the error is on bootscript. By default the bootscript

the bootscript.rcS but I can not find this file in the gem5 folder. How

can

I export this file or where I can find it ?
