Hi everyone, I would need to run a simulation of gem5 in Full System emulation with RISCV architecture with a simple C program. I therefore tried to use the --bare-metal option.
So, I tried to run the following command:
./gem5/build/RISCV/gem5.opt ./gem5/configs/example/riscv/fs_linux.py --kernel=test —bare-metal
where “test” is a compiled program written in C:
#include <stdio.h>
int main(void){
unsigned int r = 1337;
printf(“Hello World! %d\n”, r);
while (1) { }
}
and compiled with the following command: riscv64-unknown-linux-gnu-gcc --static test.c -o test
but gem5 returns me the following error:
gem5 Simulator System. https://www.gem5.org
gem5 is copyrighted software; use the --copyright option for details.

How can I fix it?
Is it correct to use the bare-metal option? Or can I do it some other way?
Does the C program need any dependencies?
