DFSDM Trigger enabled in CubeMX, but register not set

[mo_krauti]

I am trying to set up DFSDM on an stm32h753zi using the AMC1306 delta sigma modulator. I have enabled TIM8 as a trigger:

But in the registers I see, that JEXTEN is not set to external rising edge (0x1). Instead it is set as disabled (0x0).

After the CubeMX generated initialization I added:

HAL_DFSDM_FilterInjectedStart_DMA(...);

Do you have any ideas what might be causing this?

Seems like the 

HAL_DFSDM_FilterInjectedStart_DMA(...);

call fails, I need to investigate further.
