STM32H745 Disco example with eMMC + FatFs not working (FR_DISK_ERR).

Hi,

I try to run "FatFs_Shared_Device" example which supposed to demonstrate FatFs and eMMC.

I keep getting FR_DISK_ERR.

Has anyone ever encountered this issue?

I understood it supposed to work without any modification to the example.

Thanks guys

Hello @ABen .1​ ,

Welcome to our ST Community :)

Can you please provide the version of the package used?

Thanks in advance.

I've had the examples working in the past. ​The eMMC needs formatting as I recall, but that would give a different error.

Yeah you are right, the eMMC need to be formatted. I get the error "FR_DISK_ERR" when I try to create a partition using "f_mkfs". I also tried to "f_mount" but getting the same error.

The board is new and the example downloaded from STM32CubeMX.

Did this exact example work for you @Community member​ ?

Thanks!

Sure.

STM32Cube_FW_H7_V1.9.0

Is this issue fixed or still existing ?

I have ordered 1 unit of the STM32H745I-DISCO and my application include FreeRTOS and FATfs

Do you have the example code for stm32f4 with eMMC(iNAND 7250 SD) in 4-bits?
