 Description   

C66 of AM273 does not run as expected or display proper execution status when part of a multi-core group. The issues observed (so far) are:

While in a multi-core group:

  • resume command issued at the group level should run all cores and the GUI indicated all cores are running. In actuality, the C66 is never executed (though the status in the Debug view says otherwise).
  • selecting the C66 explicitly and issuing a resume command will execute the C66
  • when issuing a restart command when the C66x is explicitly selected, the Debug view indicates the C66x is running but it is actually halted at main.

These issues only occur once the C66 is added to a multi-core group AND a group level resume command is issued. Once the C66 gets in this state, the status issue will persist even if it is ungrouped. The debug session must be restarted for the issue to go away.

There are no issues with other cores in the group like R5.
