With MDK-ARM toolchain, a simple putchar function executes a SWI and activates  
a low level putchar function.  
You have to redirect the low level to your own implementation of these functions. 
 
To guarantee that no functions using the semihosting SWI are included in your  
application, either: 
 
1. Ensure that the MicroLib option is checked since the microlib does not support 
semihosting 
or  
2. Use 
- IMPORT __use_no_semihosting_swi from assembly language 
- #pragma import(__use_no_semihosting_swi) from C.

 - Low-density Value line devices are STM32F100xx microcontrollers where the  
   Flash memory density ranges between 16 and 32 Kbytes. 
 - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx  
   microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. 
 - Medium-density Value line devices are STM32F100xx microcontrollers where 
   the Flash memory density ranges between 32 and 128 Kbytes.   
 - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx  
   microcontrollers where the Flash memory density ranges between 32 and 128 Kbytes.
