[Gems-users] Problems starting simics after loading ruby

[Crispin <crigore@xxxxxxxxxx>]

Hi there.

As stated in the subject of the mail I'm having problems to continue
with the simics simulation after loading the ruby module. Following, I
paste the log of the execution:

I have searched for this error on the list, and I haven't found anything
about it. The input file "entrada-simics" contains the following:

The checkpoint is a valid checkpoint that we have used on other works.
If it helps, I'm also using a script that sets the following environment
vars:

************************************************************************************

Does someone know what's going on?

Thanks, sincerely.
