TMS320F280025: can not open memcpy function

Hi expert,

On F28034, we have another function

MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);

And we can open the define of this function in DSP2803x_GlobalPrototypes.h

However, in F280025, we provide another function, memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize);

And we cannot open it by right click the function and set open declaration.

Then I connect the device and single click into the code.

It can run into the memcpy.c file. And this file can find in

C:\ti\ccs1000\ccs\tools\compiler\ti-cgt-c2000_20.2.0.LTS\lib\src

So I want know these two questions:

1. Why can I not open the function since I include CCS resolution in my project? Does this(CCS resolution) only affect when running on device?
2. Does it safe if we cannot open the function in the project? Could you kindly help to explain the link method/process?

BR
