What's the confusion?

Have you tried using CubeMX ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hello @HA2375- 

You can start your project with STM32CubeMX for graphical clock setup.

So, in the Pinout & Configuration view, access the RCC mode panel to enable required clocks, and check the clock setup in the "Clock Configuration" tab.

Make sure to follow the hardware recommendations for crystal placement and board layout described in the User Manual of your board.
