problem with IAR code

STP
Offline

Hello
I wrote a program in IAR. The program has an error when executing the following line.

UART1_SendData8("A");

The complete program file is available below.
I would be grateful if you could tell me the mistakes of my code.

it is very short code and the error occurs in the last line
and microcontroller modell is STM8S003F3

         UART1_SendData8("A");
         var = UART1_ReceiveData8();


 	
}

    the error occurs in line 52 and error massage is : Error while running C/C++ Compiler

    Hi STP,

    Thanks for your post in Arm forum but as you are using the compiler from IAR, I would suggest you contact IAR.

    Kind regards
