Using ll_sdmmc.c with eMMC

I’m working on a project with the STM32L4 on a custom board. We want to access a eMMC to store acquired data. First, we used the HAL_sd.c library, but since it’s not compatible with eMMC, we now want to use the lowlevel ll_SDMMC.c.

But somehow the initialization does not work, and we can’t write to the card. Is there some example code concerning the ll_SDMMC, especially on how to configure the clocks? Or has someone done this before and could provide us with some code?


Thanks in advance
