Hi,

I'm trying to write on a SD card using STM32L152RE Nucleo platform. It doesn't have a dedicated interface for SD communication. Though, I try to do it through SPI3.

I must say that it is the first time I try to do that and examples (either are they for stm32l152rd or another platform using pipeline) I found doesn't help much. If someone could show me some useful codes or documentation.

Thanks

I've attached my drivers. I used CubeMX to get the file system. Then, I implemented user_diskio and microSD by looking at examples and documentation. My program hangs after f_mount in main.c
