The maximum allowed internal clock for the device STM32F446RE is 180 MHz. The nucleo board has an external crystal of 8 MHz. Using this and a code I obtained from a university website, I attempted to change the system clock to 180 MHz using the PLL.(...

Thank you for replying.I could observe that the 8 MHz crystal oscillates but it doesn't reach OSC_IN pin of MCU. Maybe because of broken PCB tracks as you mentioned. I'm not sure though. So I decided to use the High Speed Internal(16 MHz) clock as th...
