Hi,
Below is the info of my binary file which I have followed for simple.py
execution.
*>arm-linux-gnueabi-gcc myhello.c -o myhello-arm -static*
*>file myhello.armmyhello-arm: ELF 32-bit LSB executable, ARM, EABI5
version 1 (SYSV), statically linked,
BuildID[sha1]=88f5968edf2205e9debda59908a7ac233fb8ad94, for GNU/Linux
3.2.0, not stripped*
So, is this compatible with GEM5-based architecture?
I think may be EABI5 is not supporting.
Thanks
- Ikram

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.

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.
