Using ll_sdmmc.c with eMMC

Hi,

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

Best Regards

Maxim

Hi

‌,

Why don't you use the

http://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-configurators-and-code-generators/stm32cubemx.html

tool? It initializes peripherals depending on your need for the device you selected, and help you to configure correctly the clock settings. Then, you will be able to generate your initialization code.
