STM32L4R9 CubeMX - SDMMC + DMA

Hey, 

i tried to setup my STM32L4R9 with CubeMX v4.25.0 as followed:

- FreeRTOS

- FatFS

- SD Card

- DMA Support

unfortunately i noticed that the DMA-Interrupt tab does not show up in the SD-Card settings. I tried it with other STM32 MCUs where it showed up instantly. 

Is there anything i can do/configure to activate the DMA-Interrupt feature for the L4R9 in CubeMX? I saw there is an demo project with my requirements for the L4R9 on the eval board.. but would love to have it in CubeMX too! 

Regards

Hi Kevin, 

For L4+ series, the SDMMC has its own internal DMA that's why there is no DMA request
