The problem: if TIM2 is used prior to my code, then it gets stuck at a certain point, even though all the registers are properly set.* Here is the configuration of TIM2 registers when it works fine:(gdb) x/21 $TIM2_BASE0x40000000: 0x00000001 0x000000...

I'm using a Nucleo-G474RE to measure a signal via ADC1.ADC measures are triggered by TIM2, then transferred via DMA1 into a large buffer (60KB).When the buffer is full an interrupt is generated and I give the DMA another 60KB buffer.After that, every...

The code itself is fine (it works as intended, it's Nuttx by the way, and it simply sets the CC1R a few hundreds counts after the current counter and then idles). There should be an interrupt but obviously it never comes.Something is clearly not rese...

Thank you for your answer.I've edited my message to make it more readable.Shouldn't those hidden registers be cleaned too by a reset via RCC?If not, is there any way to start from a fresh configuration?The code does trigger an update event via the UG...

Thanks a lot for your quick answer.Indeed, I missed the CKMODE bits. Setting DIV2 allows me to go higher as expected, without changing the look of the output much.Setting DIV1 however produces a slightly ugly output, regardless of the sampling time.I...
