SDIO with STM32U575

Hello everyone!

I'm working on a project using an STM32U575 microcontroller, and I need to manage an SD card (read, write, etc.) via SDIO in 1-bit mode, but without using FreeRTOS.

I noticed that FatFs is not natively supported for this MCU in STM32CubeMX, and the recommended alternative is FileX, which is tightly integrated with FreeRTOS.

However, due to project constraints, I cannot use an RTOS. So I'm trying to manually integrate FatFs into the project, but I'm running into some difficulties with the integration and compatibility.

I was wondering:

  • Has anyone already done this kind of integration?
  • Is it possible to use FileX in standalone mode, without FreeRTOS?
  • Do you have any examples, documentation, or code references for using FatFs or FileX standalone on STM32U5 series?

Any help, advice, or shared experience would be greatly appreciated.

Thank you in advance and have a great evening!

Stefano
