STM32F407 Mcu clock setup

Hello sir, I have developed MCU clock setup using two functions Mcu_init and mcu_initclock in stm32f407 board. 

Now I want to develop Distribute PLL and get PLL status. Can you help me out. 

I have attached my mcu.c here for your convinience.

#include "Mcu_Config.h"
#include "Mcu_Internal.h"
#include "Mcu_RegTypes.h"

    So is your other problem now resolved:

    If so, please mark the solution in that thread.

    This seems to be the same as your previous post:

    https://community.st.com/t5/stm32-mcus-boards-and-hardware/stm32f407-clock-setup-using-registers/td-p/663048 

    So, again, why not create a working setup using CubeMX - then take the required settings from that?

    Then debug your code against the Cube code.
