It seems that Documenation ( Reference Manual) is not very clear on this point for all of you ! :-[ [ This message was edited by: STOne-32 on 18-01-2008 11:27 ]

I found that if the RCC_APB2Periph_AFIO option is used in the RCC_APB2PeriphClockCmd, the GPIO_PinRemapConfig should not be used with

GPIO_Remap_USART2 and GPIO_Remap_SPI1. Hence, I commented them as follows: // GPIO_PinRemapConfig(GPIO_Remap_USART2, ENABLE); // GPIO_PinRemapConfig(GPIO_Remap_SPI1, ENABLE);
