Part: STM32L4R5ZIT6I would like to use TIM2 to increment 3 other timers at different times:TIM2 is incrementing from an external clock and rolling over at a set period.1. TIM2 rollover would increment TIM52. TIM2 Compare 1 would increment TIM13. TIM2...

I can no longer use breakpoints. When I insert 1 I get the banner complaining about too many breakpoints. I've cleared debug configurations, breakpoints, restarted, but the problem persists. I even went to the debugger console and inserted a single b...

Thankyou for your insights and patience. I managed to get what I wanted. The two external connections were the key: My configuration is different as I'm using ETR with trigger polarity inverted:

I connected unused channels from each timer to see it operation visibly. The compare 3 and 4 have the same values that compare1 and compare2 have for TIM2. The ARR match and counter rollover should be what triggers TIM5. By looking at the waveforms f...

I have tried every possible combination in Cube and everything always happens at the same time, the rollover point. All three counters increment at the same time. One useful trick I did find out was to pause the debugger which stops the main program....

Macros seem to be a problem in general. I set a breakpoint on line 4 with the BLACK_HOLE() macro and I get multiple breakpoints. This represents the extracted code under examination:#define BLACK_HOLE(reason) system_failure(reason) if (m == 0) BLAC...

Version: Version: 1.14.1Custom board with STM32L4R5ZIT-6 microCustom OS.I've isolated the issue. It has to do with a macro that is used to create an atomic region of code. The breakpoint somehow decides that multiple breakpoints are necessary.Here is...

TIM2 as a sequencer for TIM5, TIM1 and TIM8

one breakpoint creates multiple breakpoints and debugging fails

Sometimes LPTIM2 does not start when using one shot mode. I see this happened 4 years ago to another user and their question went unanswered. So I'll try. (STM32L4R5ZIT6)
