Hello:
I want to use m5 checkpoint for my simulation.
But the way of using checkpont confused me.
Would checkpoint support TimingSimpleCPU ?
First run, I entered command:
./build/ALPHA_FS/m5.fast ./configs/example/fs.py -n1
and then entered "m5 checkpoint" and "m5 exit" in OS.
Second run, I entered ./build/ALPHA_FS/m5.fast ./configs/splash2_fs/run.py
-n1 -r1 -t
but can not restore checkpoint. Error messenge show up below.

Would the problem come up by my wrong way? or could anyone tell me how do I
solve the problem?
Thanks.
