I configured USART1 to PA9/10. And I want to use PB6/7 to GPIO.
First I initial the USART1 function(using PA9/10), and works well(putchar works well). But when I initial PB6/7 to GPIO by GPIO_Init() function, USART1 function does not work at this moment.
PB6/7 can be configured USART1 also. I think something is related this.

Please help me.
