SDMMC not working on H7 controller

Hello
I have created a new controller using STM32H743.
I added SD card for flight log and used SDMMC1 interface.
But my controller does not recognize SD card.
I formatted SD card to FAT32 and mounted it on Pixhawk6C. It works fine on Pixhawk6C.
There is no problem with SD card.
Can’t use SDMMC1 interface on STM32H743? Can only use SDMMC2?

I have a similar problem that has been bothering me for a long time. I would like to ask if you have solved it now.
