TIM1 break interrupt not firing

[bolurian]

Hi,

I am configuring TIM1 to generate interrupt via MX and I can see that the ISR for TIM1 break is added to the code.
But the interrupt never triggers. I know that break from comparator does happen, but no interrupt!

Does anyone know what could be wrong?

Did you set the NVIC?

Hello, did you eventually manage to get Break interrupts?

I see the same problem in STM32G431 TIM8.

I can generate all other events interrupts, but cant see neither BREAK nor BREAK2.

I get both breaks flags raised, but no pending interrupts from TIM8.

Something is missing.

Read out and check/show content of TIM8 registers.

Generic "interrupt does not fire" checklist here.

What can I say!? RTFM!!!!

Timer has more than 1 interrupt lines.

And!!! Lines are often muxed with it's own or other IPs interrupt lines, when connected to NVIC.

It is different for each timer (T1/T8/T20).

Pay attention to NVIC settings when expect to use certain interrupts!!!

Confusing design, though ... 

Eh ...
