Hello all,

  I'm a new user of stm32f4, and I'm trying to write on a 2GB uSD card from Transcend through a 4bits SDIO and FatFs. I'm using the code provided by CubeMX and the example from UM1721. In this manual, it's explained that we have to provide our own diskio interface. But I don't understand how to write this, what do I need to do ? Then what do I really need in all these functions / libs provided to read / write my uSDCard ? Thanks Nathan MARIN #fatfs #stm32 #sdio

Hi Nathan MARIN,

I recommend you to start form FatFs running applications under the STM32F4 cube firmware package STM32Cube_FW_F4_V1.11.0\Projects\STM324x9I_EVAL\Applications\FatFs-Syrine –
