possible bug in clock generation

I am using cube 4.21 with a STM32F205 CPU.

I configured the clock to run at 120 Mhz (25Mhz crystal M=20, N 192, P 2) in the file system_stm32f2xx.c generated by cube, I have the following:

uint32_t SystemCoreClock = 16000000;

instead of

uint32_t SystemCoreClock = 12000000;

Hi

Castrignano.Adalgiso

,

• Did you have an issue to obtain the right system clock?

• SystemCoreClockvariable takes first theHSIvalue then is updated depending on user clock configuration

• souint32_t SystemCoreClock = 16000000; is right.

Hi,

You are right, 

SystemCoreClock = 16000000 is correct.
