TMS320F28388D: Debugging CM without reloading CPU1 and CPU2

Arjan Oskam

Part Number: TMS320F28388D

Hello there,

I'm working on a project with F28388D where applications for CPU1 and CPU2 are developed in Matlab/Simulink (C2000 Support Package), and the CM application in CCS (v12.3.0) with C code.

When debugging the CM code, I also have to load (program into flash) the *.out files of CPU1 and CPU2 (built with Simulink), and then manually start them running (F8 Resume) before running and debugging the CM.

This is working just fine, however programming the *.out files into CPU1 and CPU2 flash memory takes a relatively long time, and isn't really necessary when there are no changes. Is it possible to create a debug configuration that skips programming CPU1/CPU2, and just lets me start the applications that were already programmed in flash memory? Then I would only need to load the CM application when starting a debugging session.

Thanks and kind regards,
Arjan

Hello Arjan,

see this thread:

Hi Andy,

Thanks for the link. I had already tried "Load symbols only", but not that other option. So in summary, what I needed to change in the Debug Configuration was:

On the Program tab choose "Load symbols only" for CPU1 and CPU2.
On the Target tab, select "Program/Memory Load Options" and check the option "Restart the target on symbol load as well as a program load".

Working fine now, much faster!

One follow-up question: Is it also possible to let CPU1 and CPU2 start automatically AFTER loading the CM?

Kind regards,
Arjan

In CCS you have the configuration to auto run after code load which you can enable and remove the halt option. But this will start running as soon as code is loaded.

Yes I tried that, but as you said, it starts running right after the code is loaded. I need it to start running after the last core (CM) is loaded.

I was hoping for some kind of scripting option, but I will manage manually for now.

Thanks and kind regards,
Arjan
