Symbols DNUM / TSCL compiles, but show errors in CCS

Hello,

with updating CCSv6 to latest compiler (7.4.12) and SYS/BIOS (6.41.01.36) my program compiles, but the symbols DNUM / TSCL can't be resolved (see picture).
Symbols are declared as this:

extern cregister volatile unsigned int DNUM;
extern cregister volatile unsigned int TSCL;

Cleaning projects etc. doesn't help that CCS won't show the error.

Maybe someone can give advice here?

Best Regards,
Bernd

Bernd,

The errors you are seeing are semantic errors caused by the Indexer and not necessarily build errors - that is why the project builds fine.

The trigger and root cause for this issue was never entirely clear but there is evidence it may be due to using a workspace created with a previous release of CCS, or a corruption of the indexer data. A few threads explore this:

In any case, some ideas to workaround this are shown in the reference below:

I apologize for the inconvenience,

Hello Rafael,

thanks for that hint. Creating a new workspace and importing the project works fine!
