Hi,I want to use an STM32H743 for sampling one TIM.CNT and one ADC channel synchronously and store the data of both peripherals in array buf_adc[5000] and buf_timcnt[5000]. Therefore I want to use the DMAMUX request generation and use LPTIM2 as trigg...

Serial connection is fine. It really seems to be a DMA problem.

I will check again if the serial connection, where is send data to the pc is fine. Maybe that's a problem

Thank you for answering :). At lower speeds it fails as well.You can see the output from the two buffer which should have the values from TIM12.CNT.Do you have any idea what went wrong here? It looks like a puzzle.

Is synchronous data sampling of TIM.CNT and ADC.DR with 6 MHz possible with the usage of DMA1 & DMA2 on an H743?
