Hello List, some more infos. For me it looks that SetSysClockSource or other functions in stm32f1_clk.c are broken. In case of the stm32f10C-eval (STM32F107VC) the value of new_sysclk is 180MHz. SystemCoreClockUpdate calculate a sys_clock of 225MHz. Later the Stm32UsartSetSpeed get a apbclock of 112.5MHz. Therefore the USART produce only stupid characters on the terminal.
