[gem5-users] Re: ARM and opening a file
If this works on x86, the chances are good that the system call implementations are fine since they're likely the same between the two, but there could be some glue (flag translation, which system calls that are hooked up) which is different. You should try enabling the system call DPRINTF flags (--debug-flags on the command line) to see what system calls are being called, and what they're returning. If a system call which isn't implemented is being called, there should be a message about it from gem5.

Hey Majid, Are you running in FS or SE mode? If you're running in SE mode, I don't find this too surprising as not all System calls are currently supported. Kind regards, Bobby -- Dr. Bobby R.
