I'm wondering if the STM32U5 firmware package will be extended?! I wanted to use the SDMMC and the FMC(LCD) interface but it seems that a few things are missing for it.

SDMMC: I can't select DMA for SDMMC in STM32Cube

FMC/LCD: Is there a BSP-library for easier lcd-interaction planed?

Hello @Matthias Guthörl​ and welcome to the STM32 Community :)

You'll probably want to review the examples within STM32CubeU5 MCU package:

• \STM32Cube_FW_U5_Vx.x.x\Projects\STM32U575I-EV\Examples\SD\SD_ReadWrite_DMALinkedList

• \STM32Cube_FW_U5_Vx.x.x\Projects\STM32U575I-EV\Examples\BSP
• UM2298 STM32Cube BSP drivers development guidelines

Hi @Imen DAHMEN​ 

Thanks for the Information and the links. Unfortunately I wasn't able to port the BSP example from the Evaluation Board to my Nucleo U575ZI-Q yesterday. I think I need to dive deeper into it :)

Is there any (detailed) information on how F(S)MC works (which parameter does what, how to set it up properly, etc). I think its documentation is very poor - at least I didn't find a good documentation to it yet.

I'm really having trouble understanding on how to set the timings and addresses properly to get a (smoothly) running FMC connection between my Nucleo board and the LCD screen.

Thanks in advance! :)
