How to configure the existing LLC resonant converter demo model for TI C2000 based on available model

Thank you for this, Ahmed! I was able to configure the PLECS model to accommodate the TI F28069 LaunchPad. Here is the file for your reference. I was able to run the model offline.

That being said, I am now trying to connect to the TI F28069 LaunchPad via the External Mode where I now experience this problem as shown here in the attached picture.

My initial assessment is the 90MHz system clock of the TI F28069 LaunchPad but I would appreciate any clarification on the matter. Thank you very much!

Edit: Is connecting to external mode necessary for HIL testing in the first place?
