Removing VTOR_PRESENT warning once I added CMSIS library

[Roger]

Hi,

Some time ago I could add CMSIS library with the help of @Rakshith (see the post here). His instructions were clear and since then I can run projects with the CMSIS library included. Now, what I want to do is to understand and remove the warning that I get every time I compile my projects with CMSIS.

The warning I receive says "__VTOR_PRESENT not defined in device header file; using default".

As far as I know, PSoC projects don't include a <device.h> header, but a <project.h>. And I am not sure if I have to modify something there or what exactly I have to do to get rid of this warning.

Thanks for comprehension and time.

Hi @Roger,

Have you tried to modify the define "__VTOR_PRESENT"?

Have you tried to re-generate the files and check if the warning occurs or not?

Hi @Roger ,

The Vector Table Offset  Register (VTOR) is present in ARM cortex M3  processors (which is used in PSoC 5LP).

In order to remove this warning, you can either provide the '#define __VTOR_PRESENT  1' in the file 'core_cm3_psoc5.h'. above the '#include <core_cm3.h>' This file is present in the following path
<project path >\Generated_Source\PSoC5\core_cm3_psoc5.h

You can alternatively set this define in the project build settings as well in the following manner:
Build Settings > Compiler > PreProcessor Definitions

I would recommend the 2nd method, as every time you clean and rebuild the project, the Generated_Source folder will be refreshed and you may lose any modifications you have done in the same.
