SDMMC1 and LTDC on STM32H725/35

[TRadd.1]

When configuring SDMMC1 in STM32CubeIDE, I get a warning that it conflicts with LTDC (RGB888). SDMMC2 does also conflict. Can someone guide me, how to resolve this conflict?

[TDK]

Warning can be ignored. It's letting you know you won't be able to use both at the same time.

[TRadd.1]

But I need to use both at the same time.

Switch the chip to a bigger package with more pins.

[TRadd.1]

176 pin package gives the same warnings for SDMMC1 and SDMMC2 in conflict with LTDC.

[TDK]

4 bit SDMMC1 and LTDC RGB888 do not conflict with each other.

The only conflict is with other modes of SDMMC1, which is why the message is a warning and not an error.
