I am using an STM32H743ZI and have been trying to get PWM output on timers3. I have been able to successfully obtain output for all of the pins/channels I require on timers2, and tim3_ch1_pc6 on timers3 works fine. However, tim3_ch3_pc8 and tim3_ch4_pc9 refuse to show any output on my logic analyzer. I have just been calling pwm_pin_set_cycles to test that the pins go high. Is there something going on in the background that I am possibly missing that could be causing this issue? Any help is greatly appreciated.
Here is a look at my overlay file:
