TMS320F280049: connect only debug configuration does not work when using a flash program.

Hi Neil.

Please see the below video:

Note that the Debug Configuration can be configured to load symbols for multiple cores by using the "Device" drop-down option in the "Program" tab

Thanks

Ki,

thank you for the info.  I tried this but it still did not work. I have 3 device tabs, I tried setting all three to load symbols only. 

See settings below:

Here is what the debugging session looks like when the program is loaded into flash and then debugged (this way works):

Here are each of the tabs you show above and the settings that I used (which do not work):

Here is what happens when I use this setup to debug the program:

It does look like symbols of some sort were loaded.

Can you check to see if the symbols were successfully loaded to all the desired cores by using the Modules view:

When I connect to the modules view it is empty-- no out file, no symbols.   When I flash the code using the original debug config, the symbols load in the modules view (and debugging works)

I assume that I should be loading the same symbol file as was used to load the flash code?  Would I need to compile it for RAM and use that symbol file instead?

Thank you,

Neil

That is correct. 

What version of CCS are you using?

sorry, I missed this.  I am running 10.3 on a Mac

Which version of macOS? Are you using Big Sur?

yes. 11.4

There is a known issue with CCS 10.3.x and Big Sur where sometimes views are not refreshing properly. I can also see the issue where the Modules view is blank when loading symbols only in the debug configuration. But the symbols are actually loaded and I can source step and so forth. If you bring up the context menu in the Modules view and select "Find", the symbol file should appear in the Modules view.

Ki,

In the module menu I now see symbols, However, I can't step the code.  As soon as I launch, I see this in the debug window:

The debugger seems to point to some assembly instruction and step and run do not work.  Could the fact that I do not use c_int00 as my entry point symbol be the issue?  I use "code_start".  

Another option is I could try to compile the code for RAM instead of FLASH.  Would this help? (Its not as convenient but it is possible)
