Following this thread https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1346702/tms320f28p650dk-xbar_regs, the C2000Ware has been updated including the __attribute__((noblocked)) in the f28p65_xbar.h but during compilation the #1173-D unknown attribute "noblocked" warning appear:

A solution has already been proposed by a user but it seems that it was not included in the C2000Ware update. How can i resolve this?

Hi Mattia,

Let me check with the experts and let you know.

Can you give me more details if you faced this issue while running any c28 examples in SDK?

Thanks

Hi, I faced this issue in my own project, unfortunately i did not find an example that uses the XbarRegs struct.

Hi Mattia,

Can you please use latest CCS v20.2 and check this if you are still facing this issue.

CCSTUDIO IDE, configuration, compiler or debugger | TI.com

If you are still facing this issue, we can plan to add in the upcoming release.

Thanks

Hi Mattia,

Can you also confirm with the below change, are you able to resolve the warning.

#ifdef CPU1

#ifdef __TMS320C28XX__

extern volatile struct XBAR_REGS XbarRegs __attribute__((noblocked));

#endif

#ifdef __cplusplus

}

#endif /* extern "C" */

#endif

Thanks

Hi,

i will not use CCS v20.2, we are too deep in the project and the IDE change is too much of a step at this point for us
