Timer interrupt failure - STM32G491

[famadeu]

Good afternoon,

I have a problem interrupting the TIM3 Timer, I inserted an output pin to make an alternation but no oscillation appears on the pin.

Source code attached.

I compared it with other examples and in my understanding everything seems to be fine. Would anyone have any idea what it could be?

Tks

Read out and check/post content of TIM and relevant GPIO registers.

Generic "interrupt does not fire" checklist here.
