FatFs Application for STM32H745I-DISCO not working properly

[simosilva]

SETUP: The board : STM32H745I-DISCO IDE: Keil uVision 5.28a

Describe the bug: The Application, once compiled both for CM4 and CM7 and flashed on the discovery, does not work properly.

The terminal prints the following lines:

[CM7]:  Creating FileSystem...
[CM7]:    FileSystem Created successfully!
[CM4]:       starting FatFs operation....
[CM7]:      writing on 'cm7.log'
[CM4]:      opening 'cm4.log' for writing...
[CM7]:  'cm7.log' '34' bytes written...
[CM4]:        Error!!
[CM7]:  Error!!

Checked the two codes and seem identical, the error came when CM4 try open the file with the f_open (line 147 of the main.c). Please resolve this bug thanks.

How To Reproduce simply download, compile and flash the firmware from https://github.com/STMicroelectronics/STM32CubeH7/tree/v1.9.0/Projects/STM32H745I-DISCO/Applications/FatFs/FatFs_Shared_Device ( v1.9.0 tagged repo)
