Thank you for providing details, however, your recent update does not
allow to unambiguously identify the software example you are trying to run. In
particular, the two software demos you mentioned, Router integration example and
CAN2CAN LLCE demo, belong to different software packages, each of them has it's own
list of dependencies and requires different build and startup procedures. They
cannot be combined together in any way.
For the reason explained above, the only, actually
very generic recommendation I can give based on the information you shared, is
to test your debug connection by clicking the "Test connection" button in the
debug settings window as shown below:

You can get to it by clicking the Debug Settings shortcut on the Dashboard:

Hope this helps,
