Posted on May 17, 2011 at 13:45You've switched to USART1, but you're still setting up the pins for USART2.  USART1 should be on PB6/PB7.  If you want to use PA2/PA3, I think you have to use USART2.

Posted on May 17, 2011 at 13:45You're using USART2, but you're enabling the clock for USART1.  Try this instead:   RCC_APB1PeriphClockCmd(RCC_APB1Periph_USART2, ENABLE);
