  Suggest to use LOG_printf() function, which is intended for debug and status print-out during
real-time operation. 
  Yes it is accessible from C code.

  Any function can also be accessed from asm code, but this is more difficult and not
recommended unless you have a
  specific reason and you are an advanced, experienced DSP developer.

It sounds like you are trying to call pintf()
