TMS320F28388S: CLA Halts When Attaching

Ed Sanders

Greetings,

I am using CCS 12.8.1 with a TMS320F28388S and trying to attach to both CPU1 and its CLA without disturbing the system. Both have the “Halt the target on a connect” option unchecked. When I attach to the running system, CPU1 continues running as expected. But CPU1_CLA1 halts. Is there any way to prevent that?

Thank you,

Hi Ed,

Do you have the CLA background task enabled? If not, then by nature the CLA is halted until one of the tasks get triggered since there is no main loop. Another thing you can check is if you have a __mdebugstop(); line somewhere that the debugger is hitting on the CLA core.

Best Regards,

Delaney

Hi Delaney,

No, this is not running the background task. And there are no MDEBUGSTOP instructions either. But there is an MSTOP instruction at the end of the task. I started observing where it stopped, and so far, it has always been at the MSTOP instruction. Is there any way to prevent that one from stopping it when I connect? Please note that this only occurs when the emulator connects. If I tell it to go, it won't stop on subsequent occurrences.

Thank you,
