NUCLEO-U5A5ZJ-Q - SDMMC but no FATFS in STM32CubeMX 6.13.0?

Jack3 · ‎2025-02-16

I am configuring a NUCLEO-U5A5ZJ-Q with SDMMC (1-bit) but no FATFS seems available in Middlewares in STM32CubeMX 6.13.0 for this board?

Has FATFS support dropped?

Hello @Jack3

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.

Hi Souhaib,

thank you very much, this is useful information!

Now I see "Azure RTOS FileX is a fully compliant FAT library for media storage and file system management."

However, I do not use RTOS in my application. Can it still be used in bare metal applications?
