Can't start DMA request generator (using LPTIM) by STM32H7

[SeyyedMohammad]

The file has been appended. If the program runs well we must be able to see rng_temporary is changing. But it does not change from zero. Device is STM32H743VIT6 rev V. on STM32cubeIDE 1.10.1

I've also tried to run it with dma transfer complete event but this also doesn't make DMAgenerator to work.

Since I can't delete it, I will post the answer:

Because I've missed:

HAL_DMAEx_EnableMuxRequestGenerator (DMA_HandleTypeDef *hdma)
