Hi Abhishek, I tried the baseline system without the L2 cache. I get the same error when I use the DerivO3CPU.
The command I'm using is 'build/X86/gem5.opt configs/full_system/run.py'. I have also tried with gem5.debug. run.py is same as the file available in this link: http://learning.gem5.org/book/part5/fs_config.html#running-a-full-system-simulation system.py is same as in the link except that I have modified it to use DerivO3CPU. Following are my modification: self.cpu = DerivO3CPU() self.mem_mode = 'timing' Thanks in advance for any suggestions.
