I think wang baode means copy. Not link the code in RAM space.

Hello.

You can easily copy it using memcpy.

Take a look at this code snippet:

void romFunction (void)

{

     //Do your stuff

};

void main (void)

{

  uint8_t ramSpace[1000];

  memcpy (ramSpace,romFunction,1000); //Don't care if you copy more code than needed. After function return, no code will be executed

  void (*ramFunction)(void)=(void (*)(void))ramSpace;

  ramFunction();

}

Regards.
