I have configured simple USART transmit and receive interrupt....It is working fine with othe pins for e.g PB6 and PB7.....but if I used Pa2 and Pa3 it's is neither transmitting nor receiving....What may be the problem ......

I am attaching the file

The code is initializing USART1, PA2 & 3 are for USART2

Read the manual more carefully, if you have an STM32F030x8 it's USART2, for x4 and x6 devices it's USART1
