I tried also with TIM4@STM32F405RTG6 . It shows the same behaivior. The CNT Register takes the value but the counter stops imediately and did not run again. Setting the CEN bit to 1 dont bring success.

What I have to be care for to restart the counter after loading the CNT Register ?

I assumed to reset and set the CEN bit will directly control the running mode.
