I used Cubemx to configured the system clock to 180MHz. Why is the system clock in the generated project code...... 6 zeros...... 16MHz:grinning_face_with_sweat:? Can I change 16MHz to 180MHz?It simply changes the number after "SystemCoreClock" to 180000000？

MCU starts from an internal clock, when you get the external clocks and PLL running the value will be adjusted.​
