STM32F407 clock setup using registers

[rohitkumarkv07]

Hello, 

I ty to configure the clock setup of stm32f407 board using registers .

But I am not getting the values of Registers in the SFR while debugging.

Since I am enabling the GPIOD in the AHB1ENR registers but still I am not getting the value during the debug.

Try using CubeMX to generate the setup you require, then extract the register values from that.

This is my code for stm32f407 board for the clock setup using registers. can you look at this and help me with this.

[Andrew Neil]

You haven't showed the code for your Mcu_InitClock() function.

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

Then debug your code against the Cube code.

Just on a question of style why:

Mcu_ConfigType Mcu_ConfigSet[1]=
{
		{
				&PWR_ConfigSet[0],
				&Mcu_ClockConfigSet[0],
				&FLASH_ConfigSet[0]
		}
};

instead of just

Mcu_ConfigType Mcu_ConfigSet[1]=
{
		{
				PWR_ConfigSet,
				Mcu_ClockConfigSet,
				FLASH_ConfigSet
		}
};
