TMS320F28388S: Multi Core Debugging With CCS 12.8.1

Greetings,

                When we first started developing on the 388, we used CCS 10.4.2.  This worked well, and I was able to connect to Core 1 and the CM core simultaneously without disturbing the running system by using the following sequence:

1. In the Core 1 and CM Core projects, change the ccxml file to use a GEL file which does not modify or reset the running target.
2. In the Core 1 and CM Core projects, change the Properties->Debug to uncheck ‘Halt the target on a connect’ setting for the appropriate core.
3. In the Debug Configurations, choose the Core 1 configuration
4. In the Program tab, select ‘Load symbols only’.
5. Select the Target tab to double check the ‘Halt the target on a connect’ setting is unchecked.
6. In the Device dropdown, select Cortex_M4_0
7. Select Workspace, and choose the CM core’s project.
8. Select ‘Load symbols only’.
9. Select the Target tab to double check the ‘Halt the target on a connect’ setting is unchecked.
10. Click Debug.

Now we are using CCS 12.8.1, and I am trying to do the same type of connection and not disturb the running system.  I am successfully connecting to Core 1, but the connection to the CM core is causing that core to be reset and be stuck at address 0.

Is there an additional step which I need to do under CCS 12.8.1 to be able to do the debug?

Thank you,

Ed
