1. Target board: STM32F407G-DISC1(MB997D)

2. Timer 1 and 4 configuration

3. Probing PE9 for OPM of TIM1

why 1st pwm is not working?

Is it impossible to use timer by this manner?

I found the cause that is working strangely. I did not think that FAST mode force PWM output. It is my mistake.

Solved the problem to uncheck Fast mode.
