HRTimer at STM32H743 (Nucleo board) runs half speed of full clock

Hello,

I have faced quite interesting problem when i try to obtain the pwm out on the Nucleo board. I use CubeMx to config and I set the HRTimer clock as cpu_clock (480 MHz) . When I run the code, I only get the half clock frequency driven pwm out (240 MHz) even I had no prescaler (no division selection) . I assume that the resulting maximum clock frequency of HRTimer is 240 MHz.

What should be wrong with my application, what am I missing ?

Thanks and regards,

DH..
