What version of Simics are you using? And which version of GEMS? And
please list all commands you're issuing to Simics.

Dear all,
I have created a checkpoint using the command write-configuration
<filename>. Later when I try to read from the checkpoint using
simics> read-configuration barnes-ocean-4p.check , I get the
following message

Moreover when I did a list-objects, I got the following output

I also tried modifying ruby.C and simics/interface.C (if(phys_mem0 =
NULL) phys_mem0 = SIM_get_object("phys_mem")) . But still I am facing
the same error. I would really appreciate it, if any one could help me
out.
Thank you for your time.
Regards,
Avinan
