Hi Team, I have written a c code (hello world program) and compiled using the arm cross compiler. When I run the simple.py config file with new helloworld binary updated in simple.py file I am getting simulation failure. c code is as shown below: *#include <stdio.h>int main(int argc, char* argv[]) { // printf() displays the string inside quotation printf("Hello, World!"); return 0;}* ARM cross compiler used : *aarch64-linux-gnu-gcc* Below are the commands I used: *aarch64-linux-gnu-gcc -static -static-libgcc -static-libstdc++ myhello.c -o myhellobuild/ARM/gem5.opt configs/learning_gem5/part1/simple.py* Below is the error: gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 version 21.2.0.0 gem5 compiled Jan 24 2023 23:16:23 gem5 started Jan 24 2023 23:21:13 gem5 executing on ubuntu-linux-22-04-desktop, pid 156963 command line: build/ARM/gem5.opt configs/learning_gem5/part1/simple.py Global frequency set at 1000000000000 ticks per second warn: failed to generate dot output from m5out/config.dot build/ARM/mem/mem_interface.cc:791: warn: DRAM device capacity (8192 Mbytes) does not match the address range assigned (512 Mbytes) 0: system.remote_gdb: listening for remote gdb on port 7000 Beginning simulation! build/ARM/sim/simulate.cc:194: info: Entering event queue @ 0.

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. * On Tue, Jan 24, 2023 at 9:40 PM IKRAM via gem5-users <gem5-users@gem5.org> wrote: > Hi Team, > > I have written a c code (hello world program) and compiled using the arm > cross compiler.

Hi Ikram, It seems like your program is using a system call (#398) which has not been tested or implemented in gem5. This can be because of a newer version of the c library or compiler. One option is to ignore this system call and see if your program still works. As a reference you can look at how the other system call in your program is ignored (set_robust_list) in the gem5 source code here: "src/arch/arm/linux/se_workload.cc". -Ayaz On Tue, Jan 24, 2023 at 10:12 AM IKRAM via gem5-users <gem5-users@gem5.org> wrote: > Hi Team, > > I have written a c code (hello world program) and compiled using the arm > cross compiler.

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.
