F29H850TU: Core 3 stuck in free-running state

Part Number: F29H850TU

Core 3 stuck in free-running state when attempting to connect it to load symbols

I am using"Project-less Debug" Workflow on CCS 

  1. Build the combined project (the one that includes binaries for all cores).

  2. In the Project Explorer, right-click your .ccxml target configuration file and select Start Project-less Debug.

  3. In the Debug window, manually connect to CPU1 first.

  4. Load the Program (.out) onto CPU1.

  5. Run CPU1 until it hits the ESTOP or the point in the code where it initializes the other cores.

  6. Only then connect to CPU3 and select Run > Load > Load Symbols.
