Can't send data through the USART Tx Pin in the STM32F411E-Disco Board

I am trying to Initialize and send data through PA3 (USART2_TX). When i connect the pin to a Serial to USB module to see the data sent on the terminal (CoolTerm) I get an error and doesnt' work. I set the baud rate based on that I have an 8MHz crystal on the board and still nothing is working. What is wrong in the code?

1. void USART2_Write(int ch){
3. while(!(USART2->SR & 0x0080)) {} // Wait on TXE
4.  
5. USART2->DR = (ch & 0xFF); // Then send
6. }

I edited the code but there is a still a problem. I get the following error in CoolTerm "103 BreakCondition". I search and I found out that it is usually due to Hardware detected a break condition. Usually due to a signal rate mismatch. Is it a problem with the baud rate ?

You might want to add comments about the pins, clocks and expectations.

Baud rate looks to be ~9600 baud from 8 MHz APB1

AFR[1]= 0x00000070; // Is NOT PA2

AFR[0] = (AFR[0] & 0xFFFFF0FF) | 0x00000700; // PA2:AF7
