TIM14 OC1 Trigger into TIM2 on STM32G071

[danielbathtub]

Hi, 

 

Has anyone managed to Trigger Timer 2(Combined PWM Mode, One-Pulse) with Internal Trigger 3(ITR3). The TIM14 OC1 waveform is the trigger. When I run Timer 14 in output compare mode, with an active level on match between Couner and CCR1. I cannot trigger the Timer nothing happens. If I go an manually trigger the timer, everything works.  Here is my Software to setup Timer 2 in Combined PWM Mode 2, on channel 2, One-Pulse Mode. 

 

Image on the left is the TIM2 code and imagine on the right code for Timer 14. I have verified this works by using the debugger and seeing that TIM2 is never enabled even if the OC1 Signal on Timer 14 goes high

hello @danielbathtub 
Can you share your .ioc file?

My Software doesn't rely on anything from Cube. 
I don't use the IOC file, and yes I did enable the peripheral clocks before running these routines. 

My experiment of using Cube I cannot achieve the above even with the IOC file

Settings look reasonable.

I don't have a 'G07x to try, but I'd try to toggle TIM14, perhaps in one of the PWM modes; maybe even in the debugger by forcing it high/low alternatively. Also, if there is some non-default APB prescaler, I'd try to use the default one, perhaps also try to run at the default clock settings altogether.
