Hi,
First of all, you do not need to edit the script file to run a workload!!!
You can run the workload (you hello world program) just by passing it as
an argument in your command line. It is not a good idea to modify simple.py
just to run your program. Assume you have multiple programs you need to
test them in Gem5. Is it correct to modify the simple.py every time you
need to run the simulation? Absolutely no.
The simple.py has multiple arguments you can pass them in your command
line, one of them the target binary program, i.e., hello world program.
The following command line will start gem5 (x86 arch) with default
configuration to run a hello program that is located on a particular path.
*./build/X86/gem5.opt configs/example/se.py -c ~/Desktop/hello*
This cross-compiler "
*aarch64-linux-gnu-gcc" generates a 64 bit binary, what is your Gem5-based
architecture? Is it aarch 64? I prefer to simply compile the hello world
program just like Cross-compiler hello.c -o hello , without other
arguments. *
*Please could you provide us with info about your architecture and binary
file (just type in linux terminal $> file hello) to know is it compatible
with the target Gem5-based architecture. *
