Hello
Thanks a lot Evangelos for directing me how to write a script for linux on
sparc. I wanted to share it, for everyone's benefit and probable correction.
(See in the end).
When I execute this file, it generates the flexus_test_warmup easily,
however when I try
./create-initial-flexpoints TraceFlex
it gives the following error.
=======================================================================================
./create-initial-flexpoint TraceFlex

More than one simulator binary is built. Don't know which one to use.

=======================================================================================
When I compile for x86, everything till run-timing-jobs is fine. I fear that
in prepare-test-app-v9, the file says:
run-command-file "serengeti-6800-system.include" #we have modified this file
and moved it to the local directory
I am not sure, what this modifcation should be for sunfire-6500 case, so I
have directly included the cashew-common.simics (instead of writing three
run-command-file).
Can you kindly help me with this? I am using simics 3.0.31, is it that a
proper version of simics (3.0.27, 3.0.30 etc) is required for -ma to run or
some other error? I will be grateful for the help.
