Hi 

Im using CrossStudio for ARM and I opened some example provided by ZMDI found in  IDT_ZWIR45xx-Software-Rev1p9p1971_SWR_20160408, namely ADC Input example project.

 

I can not build the project . 

 I get the following errors:

Checking project status

  These functions are now supplied in [thumb_]crt0.s - add local definitions

  void __heaplock() {}

  void __heapunlock() {}

  void __printflock() {}

  void __printfunlock() {}
