TMS320F28379D: Can Eclipse navigate to library code.

Hello Cameron,

WhiteNoise said:

Firstly is my assumption right and "s_sin.c" does contain the implementation called when using sin() ?

I would hazard to say yes, although the best way to find out is running an example and stepping into the function in a separate project (you may need to use the Disassembly window to assembly step-into the function).

Secondly how do I tell Eclipse to navigate to this code when I hit F3 but not have it try to rebuild the library ?

I will let a CCS expert speak on how to make sure CCS behaves this way.

Hello Cameron,

Please see:

Thanks

Debug confirmed it was indeed implimented in "s_sin.c", thanks for the tip Omer.

Checking the link now Ki.

Ki that article didn't address my problem. Eclipse can step through the library code while debugging on a device, however when not debugging Eclipse can't F3 and jump to definition.

Hi Ki,

If I add the paths does this not then lead to the problem that CCS will try and compile the the library code again ?

I think this is the setting page you are referring to :

However there is no option to add *.c files:

You just need to specify the additional directory for the indexer to parse. You do not specify individual files. You'll also likely need to set it for both the C and C++ settings.

Thanks

ki

So I just select the "Include Directory" option and point it at the root directory that contains the library C files ?

That's correct.

I have added the directories as suggested (snip attached of how I added them). I enabled the "Treat as built-in" option as the Eclipse documentation says the following about it;

 The directories are added for "TI GNU C" and "TI GNU C++", I also tried "TI Assembly" for the hell of it but it made no difference.

The indexer log file confirms it is using them and the index has been rebuilt.

Local Include Search Path (option -iquote):
   C:\ti\ccs1250\ccs\tools\compiler\ti-cgt-c2000_22.6.1.LTS\lib\src
   C:\ti\C2000Ware_5_00_00_00\driverlib\f2837xd\driverlib

However still no joy going from my sin() call to the implementation with F3.

Any more suggestions ?

I gave this a try and I ran into the same issue. I also try playing around with the "paths and symbols" settings with no luck. If I link the whole source folder to the project then it can find it but of course we don't want that.

I'll need to see what limitation there is that is preventing the proper indexing

Understood, many thanks for the continued effort !

Note that there are several known issues with the indexer so if the issue is specific to the indexer then we may not be able to do much to fix it. We'll take a look to see where the issue lies.

Absolutely understood. In trying to fix this I have already stumbled across reports of similar long time unfixed indexer issues in Eclipse. Hopefully they were just similar and this issue can be fixed, fingers crossed.

Please note that active development on Eclipse/CDT has slowed these days as it is a dated environment. There is much more active work done with Eclipse Theia. Also note that CCS is moving away from Eclipse IDE to Eclipse Theia IDE. The next major CCS release will be based on Theia IDE. Because of this, we are deprecating support for CCS Eclipse/CDT issues. 

I have installed Theia and it appears to have the same problem, I also can't find the equivalent of where to add extra indexer paths.

Yes, the indexer performance in CCS Theia is not yet at par with CCS Eclipse. We still have some work to do with CCS Theia.

OK, please let me know if you find a resolution for Eclipse/CDT in the meanwhile.

Will do.
