TMS570LC4357: Difference between _getCPSRValue_ and _get_CPSR?

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

Why is the FreeRTOS port generated by HALCoGen using _getCPSRValue_() instead of _get_CPSR() in the the implementation of pxPortInitialiseStack? What is the difference between these two functions? This information cannot be found in any manuals.

To be clear _get_CPSR is document, but _getCPSRValue_() not.

Hi,

The _get_CPSR is one of the intrinsics defined in TI ARM compiler. You can use either _get_CPSR() or _getCPSRValue_() in your code if you use TI ARM compiler to compile your project.

The _get_CPSR() may not be defined in other compiler, so the _getCPSRValue_() can be used to read CPSR value.
