Hi all,

I will configure HSE_VALUE = 8000000 and defined

#define HSE_VALUE    ((uint32_t)8000000)

#define PLL_M      8

#define PLL_Q      7

#define PLL_N      336

#define PLL_P      2

And I defined line option : -DHSE_VALUE=8000000

My stm32f3-discovery connected to PC via (USB to COM) (FTDI - FT232) use UART4 and PIN PC10&PC11(TX & RX) and GND, but the Terminal on PC will received wrong !

How I passed this error?
