STM32F767 clock frequency configuration

Hi everyone,

Using the STM32 -F767 board with freertos, and the CubeMX we are trying to change the clock speed via the clock configuration tab in order to lower the power consumption.

After changing the HCLK to the desired speed (32MHz) or any other speed, generating the code, and running the application, I can see that the variable SystemCoreClock is indeed changing from the default value of 16000000 to the desired clock speed after calling SystemClock_Config function.

But still, the power consumption is staying very high and is not suitable for the consumption we should get with a clock speed of 32MHz.

Any ideas on how to approach this issue?

Thanks!
