Here is an example for all of you that are still stuck with the same problem.

In the example, you can find the project file for STM32CubeIDE and STM32CubeMX.

I'aware of the fact that the code is clumsy but it will give you an idea on how to set some of the parameters for the MCU.

The example works with SDIO 1 bit mode.

Few things to be aware of:

  • The code runs on a custom board where pull-up resistors of 10K are placed on the SD card pins :0693W00000AOMt6QAH.png

  • The SD card installed is 32GB, I first format the card with the PC and then plug it on the board. The first time f_open() gives an error, I reset the MCU and run the code again and from then on it works well, meaning I can create the file, write some text and read it back. Perhaps the time to set up the disk it too short the first time, I still have to debug it.
  • Be aware of the SD card that you are using, I have also been using a 16GB card without success, only to later find out the card was corrupted.

Hope it helps.

Once again, thanks to everybody for the answers, they have been of great help anyway.

Hello @DFres.1​ 

Have a look at the SDIO library code and the examples within STM32CubeF4 MCU package:

STM32Cube_FW_F4_V1.26.1\Projects\STM32F413H-Discovery\Applications\FatFs

You can follow the guide to import Cube projects from SW4STM32 to STM32CubeIDE:

Thank you for your prompt reply, I should have specified better the question.

What I am interested in, is the full project files including also the .ioc extension from CubeMX.

Meaning, the example starting from CubeMX to CubeIDE.

When you use C (not C++), you can generate the project with CubeMX, after generation is done, press open then the project will be imported to IDE and you can continue with IDE without using MX anmore. You can also import the project in IDE.

Hello @DFres.1​ ,

I have attached an SD card example with STM32CubeIDE.

I hope this help you.

Walid.

Thank you for your prompt reply Walid,

I have however tried your example but without any success. The board I am using is the Nucleo-F413ZH.

I would like to see all the MX configuration if possible

Even easier ... let's rely on example browsing import and feature ...

Either from welcome page or from File > Import > General > Import STM32Cube Example

I would like to see the MX configuration for clock settings and peripherals and then the code.

Unfortunately sounds no example supporting configuration
