Thank you for your answer. but the problem is that I can't really change of compiler. I am using m5sim to precisely simulate the executable obtained with this compiler (arm-elf-gcc v.4.2.2). I checked and it supports the EABI.
After some research I made today, I think the problem is more than the target code is not meant to run on Linux but rather on bare metal. Does that mean I will have to deal with the Full System implementation ARM_FS (which does not yet exist) ? I'm still confused with the steps made by m5sim at the beginning of the simulation and in particular the loading of the executable specified as 'workload' of the cpu in the pyhton config file. Is this the write way to specify the software I want to run on the CPU ? Is there an hidden bootloader somewhere ? Does the SE mode boot a Linux and then launch the 'workload' as a standard process ? I have had a hard time finding these information on the wiki or the web. ----- Original Message ----- From: "Ali Saidi" <sa...@umich.edu> To: "M5 users mailing list" <m5-users@m5sim.org> Sent: Wednesday, July 21, 2010 4:44:41 PM GMT +01:00 Amsterdam / Berlin / Bern / Rome / Stockholm / Vienna Subject: Re: [m5-users] Simulating software with ARM_SE The compiler you compiled your executable with is too old.
