Hi,
I would like to create a project with CubeMX where I handle files on a SD card with FAT Fs file system using a STM32U5 mcu.
When I select the STM32U5 MCU in CubeMX the FATFS middleware is not available, while If I select other MCUs series like STM32F for example the FATFS Middleware is available.
I tried to find the FATFS software package to manually install it into CubeMX but I haven't found nothing.
Is FATFS middleware available for STM32US MCUs for CubeMX ?
Thanks for your help.

Thanks.

A complex system designed from scratch never works and cannot be patched up to make it work.

Thank you @Andrew Neil for linking that post.
From that discussion it seems like there is no intention from ST to support FATFS Middleware for STM32U5 MCUs in CubeMX at all am I right ?
If we want to use FATFS we need to get the source code from https://github.com/STMicroelectronics/stm32_mw_fatfs/tree/master include it in our projects and configure it manually ?
I do not want to use FileX in my project since it doesn't need to run with RTOS.

Hello @jacopokunak ,
In the STM32CubeU5 firmware, the file system has been migrated from FATFS to FileX.
I suggest that you to take a look at this POST in order to know more about it.
It demonstrates also how to develop a basic SD card file operations application.
Thanks.

@Mahmoud Ben Romdhane does FileX require the use of the Azure® RTOS, or can it be used standalone?

Following the FAQ link from that page, I got to this:
It's not very helpful to say, "refer to the relative ST Wiki page to get more information" when none of those Wiki pages exists!
